Leeward Renewable Energy Development, LLC 5 Burns & McDonnell February 11, 2019 Weld County Department of Planning Services Mr. Chris Gathman Planner Ill 1555 N. 17th Avenue Greely, CO RE: Mountain Breeze and Panorama Wind Energy Facility; Response to Weld County Completeness Review Comments for PRE18.0289 Dear Mr. Gathman, Leeward Renewable Energy Development, LLC. (Leeward) is pleased to receive the Weld County Completeness Review Comments for the Mountain Breeze and Panorama Wind Energy Facility Project dated January 28, 2019. We reviewed the comments and respectfully submit our responses for your consideration. Weld County Department of Environmental Health 1. provide the well permit and the septic permit for the cedar creek building that will be used for an office. Include how many people will be using the office. Indicate that portable toilets will be used for construction workers. where will water for dust control be obtained? will there be odor from batch plants? if so, how will that be addressed? Provide answers in one document that is easily located. If you have any questions regarding these requirements — contact Lauren Light — Ilight anweldgov.com or (970) 400-2211 Response: a) Leeward has included the Cedar Creek well and septic permits for their operations and maintenance building in Attachment 1 of this document. b) Anticipated on -site employees at the Cedar Creek Operation and Maintenance Building are discussed on pages 5- 12 and 5-13 of the applications: During operation of the Wind Energy Facility, Leeward will have between 15 to 20 part-time, full-time, or contractor employees (e.g., site manager, operations manager, and operating technicians) on site who will be responsible for operating and monitoring the facility, including coordination of all scheduled maintenance as well as forced outages and equipment malfunctions. Leeward staff includes approximately 30 part-time, full-time, or contractor employees that currently maintain Cedar Creek I. If required, Cedar Creek I will expand their existing facilities to accommodate the increase in operation employees. Cedar Creek I will seek the authorizations necessary for any expansions. c) The construction contractor will utilize temporary portable toilets during construction. This is stated on page 5-33 of the application. d) Water for dust control is address on Page 5-33 of the application: During construction, water for the concrete batch plants, dust control, and drinking water will be obtained by the construction contractor from existing permitted sources. In addition, port -a -johns will be used at select locations in the Project during construction which will be used by wind farm employees, construction workers, and contractors. Page 1 of 4 e) Any odor generated from a concrete batch plant is anticipated to be temporary, localized, and have minimal impact on adjacent lands. Weld County Department of Planning Services 1. Previous 1041 projects involving powerlines have shown a corridor (say a 500 -foot wide area) for the transmission line — allowing some flexibility where the transmission line could be located within the corridor). I am processing a USR (USR18-0100) for a Public Service powerline where the applicant is doing this. The application indicates that all easements along the routes have not been acquired. I would advise the applicant to show a corridor to allow for some flexibility of alignment of the transmission line. Response: Leeward has updated and attached (see Attachment 2) the following figures to include a 500 -foot corridor representing the transmission line area: • Figure 2-1 • Figure 2-2 • Figure 2-3 • Figure 4 Leeward has also updated text in the application to reflect the 500 -foot transmission line corridor. Updated pages with modified text are included in Attachment 3 of this document. 2. I am unclear as to whether this is meant to operate as a single project/USR. The application lists two entities (Mountain Breeze and Panorama) — that will ultimately connect to separate substations? Does this intend to operate as one project? Or is the intent to sell and/or operate these as separate facilities? Response: Leeward Renewable Energy Development, LLC has leased the entire project area and developed it for purposes of wind generation. The facility is being developed/designed permitted to operate as one large facility. Leeward owns all three entities mentioned above along with the existing Cedar Creek Wind Farm which it has been operating since 2007. Mountain Breeze Wind, LLC and Panorama Wind, LLC were formed as subsidiaries of Leeward Renewable Energy Development, LLC. The facility will have some distinct differences such as separate interconnection points and power off take contracts. Due to these separate key project contracts and hence the likelihood that they will be financed separately Leeward concluded that this structure was best suited to finance the project by creating the separate project entities mentioned above. 3. Batch Plant/Laydown yards — How long does the batching facility intend to operate? (less than 6 months/more than 6 months?) — Once I have a timeline I will get clarification with our staff/my supervisors as to whether the batching facilities can be incorporated into this USR or needs a separate standard USR application. The application indicated up to 2 batch plants and 2-4 laydown yards. Two (2) laydown yards and batch plant are shown at the substation sites. Are any other laydown yards going to be added and do you have those locations? Also — if you have any specific information about # of construction trailers/conex containers association with construction (include with the application). In instances where we do not have this specific information — separate zoning permits (ZPMH) will be required for the trailers. Page 2 of 4 Response: a) The batch plants will operate for 6 months or less. b) One batch plant will be operated by each wind energy facility; one for Mountain Breeze Wind Energy, LLC and one for Panorama Wind Energy, LLC (see revised figures 2-2 and 2-3). c) Two laydown yards will be required; one for each facility. One laydown yard for Mountain Breeze Wind Energy, LLC and one laydown yard for Panorama Wind Energy, LLC (see revised figures 2-2 and 2-3). d) Leeward will have 2-3 temporary construction trailers and their Balance of Plant (BoP) contractor will have 3-4 temporary construction trailers. 4. Substations — Are the substations to be located on areas to be leased from property owners/or is it going to be owned by the applicant. Utility Service Facilities are required to be located on either a subdivision exemption lot (in the event of a lease) or a recorded exemption lot (in the event the applicant is purchasing the parcel). This can be processed in conjunction with the USR. However — I need some more detailed information as to where these two (facilities will be located). It is hard to pinpoint the proposed substation location on the large scale maps. Do you have a separate map/exhibit — showing the boundaries of the proposed substation sites? USR18-0100 — the last transmission line we did — provided a separate site map for the proposed substation site. Response: Leeward has executed lease agreements with landowners where substations are proposed (see revised Figures 2-2 and 2-3). Additionally, Appendix M of the application has several site specific figures for the substation locations. 5. Powerline endpoint — the application under project overview (page 1-3) — indicates that the transmission line will end at the Junction/Panorama Substation (or similar facility). I recommend removing (or similar facility) from the application. Unless you are going to build another substation in this vicinity — if so this would need to be specifically included in the application. Also (if you have any specific or at least general layout of the staging yard showing or at least describing the maximum number of job trailers and conex containers) at each site — I would include with the application. Response: a) Leeward has agreed to remove the language referencing "or similar facility" in the application. Revised application pages are include in Attachment 3 of this document. b) For construction job trailer information please see response 3-d above. 6. The application form has two signatures from parties not listed on the application. Please provide some form of corporate authorization or Statement of Authority indicating that they have authorization to sign the application on behalf of Leeward. Response: Leeward has provided the appropriate corporation authorization documentation for the application signatories in Attachment 4 of this application. 7. Once the application is determined to be complete (or close to be complete) — be sure to contact our County Attorney — Bob Choate — bchoate(a.weldgov.com. Because this a 1041 application — the County will need to reach an agreement with you specifying hearing dates for the Planning Commission and Board of County Commissioners. Response: John Wycheriey and Bob Choate have exchanged correspondence via telephone and email. Bob Choate provided a draft agreement for Leeward consideration on 2/1/2019 via email.

The Project is designated by Weld County as a Major Facility of a Public Utility, (1041), and a 1041 Permit is required from Weld County for the proposed Project. This application describes the Project and provides information required by the Weld County 1041 Regulations. The Applicant is requesting approval of a permit to conduct an Activity of State interest as authorized by Title 24, Section 65.1-501 of the Colorado Revised Statutes (CRS) and Chapter 2 I, Article i-111 of the Weld County Charter and County Code. The Activity of State Interest involves construction, operation, and maintenance of a Major Facility of a Public Utility as defined by Weld County Land Use Code 21-3-20, which is applicable to the Project even though the Applicant and the Project are not subject to regulation by the Colorado Public Utilities Commission. Leeward is a premier renewable energy developer based in Dallas, Texas whose parent Leeward Renewable Energy, LLC owns and operates over 1,700 MW of operating interests in 19 wind projects across nine U.S. states. Leeward and its predecessors have been developing and operating renewable energy projects since 2003 and has expertise and experience in development, energy markets, construction, financing, asset management, engineering operations and corporate functions. Leeward has also successfully developed and constructed projects with a wide range of offtakers ranging from some of the largest utilities in the country to regional and municipally owned utilities throughout the U.S. Leeward is actively developing opportunities to expand its energy portfolio through high return investments in the existing portfolio, mergers and acquisitions as well as greenfield development of wi nd, solar. and battery storage. Leeward Renewable Energy Development, LLC 1-3 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Approach to Site Selection 2.0 APPROACH TO SITE SELECTION 2.1 Wind Energy Facility The Project Area was selected based on several key developmental factors that include, but are not limited to, the wind resource in the area, environmental consideration for appropriateness, transmission characteristics, and economic considerations. Colorado is a leading state in wind energy generation in the United States, including Weld County in particular. An assessment of \kind speed was initiated on the neighboring Cedar Creek I Wind Farm, located adjacent to the west and south of the Project, in 1996 by the U.S. Department of Energy's Utility Wind Resource Assessment Program (UWRAP) to evaluate potential sites in Colorado. Of the 10 sites evaluated, the Cedar Creek I site had the highest average documented wind speed and it was determined the predominant winds coming from the northwest experience an increase in velocity as they encounter the hills that lie perpendicular to the winds. In addition, the National Renewable Energy Laboratory (NREL) Colorado 80 -Meter Wind Resource Map shows modeled average annual wind speed at 80 meters within the Project Area at 7.0 to 8.0 meters per second (m/s) (U.S. Department of Energy, 2010). Areas with annual average wind speeds around 6.5 meters per second and greater at 80-m height are generally considered to have a resource suitable for wind development. Leeward has been studying wind resources within the Project Area for 15 years and currently has three temporarily permitted 60 -meter met towers in the Project Area. This application requests authorization to construct up to 6 permanent met towers at approximately hub height. When operational, the Project will have a total of three permanent met towers at the Mountain Breeze Wind Energy Facility and three permanent met towers at the Panorama Wind Energy Facility. Two new substations will be required in order to centralize the power generated by the turbines then transport it offsite. In each case, the project -specific substation was centrally sited and will accommodate the turbine generation in that project area, as shown in Appendix A Figure 2-1. 2.2 Public Involvement Public involvement during the development stage of the Project helps identify the concerns related to the Project and is one of the most important factors in the energy facility siting process. Input from jurisdictions, agencies, and landowners has become a major focus in siting new utility and generation facilities. Public outreach and agency correspondence are included in Appendix B. To obtain the public's input, Leeward has conducted the following meetings: Leeward Renewable Energy Development, LLC 2-1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Transmission Facilities 3.0 TRANSMISSION FACILITIES Two new interconnection transmission lines, approximately 15- and 11 -miles in length (Transmission Facilities) will be required to export the electric power generated at the Project. For analysis purposes transmission line corridors of 500 -feet wide were created for which the transmission line and associated ROW will be located within. The corridors were created to provide flexibility for engineer design and sensitive resource avoidance. Both transmission line corridors were selected based on general locations for the Wind Energy Facility and on -site requirements, engineering, and electric system planning needs. The interconnection transmission line associated with Mountain Breeze Wind Energy Facility will be approximately 11 -miles long and 230 -kilovolts (kV), connecting to Junction Switch Yard or similar facility (Mountain Breeze Transmission Facility). The Mountain Breeze Transmission Facility analyzed three alternative alignments, these alternatives are shown in Appendix A Figure 2-1. The Preferred Alternative was selected based on interconnection considerations, land acquisition considerations, avoidance of environmental resources, and avoidance of other facilities (military and utilities) and is presented in the remainder of this application for analysis and request for approval from Weld County. Part of the transmission line will traverse lands which are currently part of the Cedar Creek Wind Energy Projects. Sub -easement agreements will be in place with the Cedar Creek Wind Energy Projects where required. The interconnection transmission line associated with Panorama Wind Energy Facility will be approximately 15 -miles long and 115 -kV, connecting to Redtail Substation or similar facility (Panorama Transmission Facility). The Panorama Transmission Facility analyzed two alternative alignments and these alternatives are shown in Appendix A Figure 2-1. The Preferred Alternative was selected based on interconnection considerations, land acquisition considerations, avoidance of environmental resources, and avoidance of other facilities (military and utilities) and is presented in the remainder of this application for analysis and request for approval from Weld County. Part of the transmission line will traverse lands which are currently part of the Cedar Creek Wind Energy Projects. Sub -easement agreements will be in place with the Cedar Creek Wind Energy Projects where required. Mountain Breeze and Panorama Transmission Facilities were determined based on the following criteria: • Shortest length between the proposed Project and the existing substation • Buffers surrounding the existing Cedar Creek I and Cedar Creek II turbines • Buffers surrounding existing buildings and residences • Buffers surrounding military infrastructure Leeward Renewable Energy Development, LLC 3-1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Transmission Facilities • Coordination with Colorado Parks and Wildlife to avail sensitive wildlife species The Mountain Breeze and Panorama Transmission Facilities locations are shown in Appendix A Figure 2-1. The routes were sited to have minimal impacts to area buildings and residences as well as to the existing Cedar Creek I and Cedar Creek I1 Wind Farm turbine arrays. To date, all easements along the routes have not been acquired. Leeward requests the ability to slightly modify the routes based on final Project design and easement acquisition. Final route easements and specific engineering design will be provided to Weld County prior to Project construction. Leeward Renewable Energy Development, LLC 3-2 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Wind Energy Basics 4.0 WIND ENERGY BASICS The basic components of a wind energy facility include the turbines, foundations, power collection system, and roads. Wind energy production includes the following five basic components, which are also shown in Appendix A Figure 2-1. 1. Electrical Power Generation — Wind blowing against the turbine blades causes the blades to rotate, which in turn rotates electrical generators that produce electricity. 2. Energy Transfer — The generated electricity is fed through cables within the tower to a base panel at ground level inside the tower. The electricity is then fed to a pad -mounted transformer located adjacent to the tower that increases (steps up) the power to a higher voltage of 34.5 -kV. 3. Collection System — The stepped -up power from the transformer is fed into a collection system. Power collection lines connect groups of wind turbines in the field to a substation. 4. Substation — At the substation, the voltage is increased to the same level as the utility grid so that it can be fed into the electrical transmission system. For the proposed Project, the voltage will be increased to 230 -kV for the Mountain Breeze Project and 115 -kV for the Panorama Wind Project. 5. Utility transmission — Electrical energy is sent through the transmission lines to utility distribution systems for delivery to customers. Two transmission lines, Mountain Breeze Transmission Facility, approximately 11 miles in length, and Panorama Transmission Facility, approximately 15 -miles in length, will interconnect the Project to the electric grid for delivery to customers. The Mountain Breeze Transmission Facility will tie into Junction Switch Yard similar substation and Panorama Transmission Facility will tie into Redtail Substation or similar Leeward Renewable Energy Development, LLC 4-1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.6.4 Type of Facility (21 -3-330.B.5.e) The elements of the Project include up to 140 wind turbines, access roads, electrical collection lines, substations, two transmission lines, an existing O&M facility, and associated supporting infrastructure and facilities. The Project also includes the following temporary construction facilities: concrete batch plant areas, staging and parking areas, and a construction office trailer complex. Leeward will have 2-3 temporary construction trailers and their Balance of Plant (BoP) contractor will have 3-4 temporary construction trailers 5.6.4.1 Wind Energy Facility Wind Turbines Wind turbines convert the kinetic energy of the wind into the rotational energy of a rotor and drivetrain. This energy is in turn converted into electrical power by industrial generators integrated within the wind turbine housing. An automated `pitch' system will control the speed of the rotor by turning the face of each rotor blade into or out of the wind. Modern wind turbines typically produce energy in a wind speed range of 3.1 to 25 meters per second or 7 to 56 miles per hour (mph). Power quality will be further accomplished through the use of power electronics, which convert generator output to achieve required output voltage and frequency control. An integrated wind speed and direction monitoring system works with a `yaw' motion control system to keep the face of the turbine presented into the wind. Leeward intends to use a GE 2.X platform turbine models for the Mountain Breeze Wind Project. The final model selected will be based on availability and the highest compatibility with the site requirements (i.e. cost efficiency, manufacturers' availability, optimization of wind, land resources setbacks, environmental concerns, etc.) will be provided to the County as a condition of approval. The wind turbine output possibilities for this Project will range from 2.3 -MW to 5.8 -MW. The Wind Energy Facility layout is designed to accommodate any of the wind turbine output possibilities. Appendix K provides representative wind turbine models under consideration for the Project. Table 5-lTable 5 1 is representative of the wind turbine options under consideration; however, the Project may opt to use a wind turbine or combinations of wind turbines not included in the list. Leeward Renewable Energy Development, LLC 5-8 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) facilitate crane travel and turning radii to facilitate deliveries of wind turbine components may be necessary. The proposed haul routes identified for the Project are detailed on Appendix A Figure 15. Following completion of construction, use of the improved and new access roads on private land will be limited to landowner and maintenance staff. Temporary road improvements such as shoulders on roads and expanded turning radii, and construction work areas (such as crane pads and erection areas) will be de -compacted and reseeded using an approved native seed mixture upon completion of construction. Both gravel and water will he required for road construction, concrete production, dust control, and other construction activities. These commodities may be provided from either existing, permitted off -site sources or newly developed and/or permitted on -site sources. If on -site water supplies or gravel pits will be developed, Leeward will comply with all local, state, and federal permitting requirements regarding development and use of such on -site sources. However, it is expected that the sources of water and gravel to be used for the Project will be similar to those used for the existing Cedar Creek i Wind Farm. Gravel and water required for construction \\ ill be obtained from existing permitted facilities . Section 5.9 (21-3- 330.C.2.g) provides a discussion of construction traffic routes and transportation considerations. Collection System A 34.5 -kV electrical collection system will gather the electricity from each wind turbine and route it to the interconnection substations. The majority of the collection system will be installed underground, typically along the rows of the wind turbines. Remaining portions will be installed aboveground. ty inu the rows of turbines together forming a "backbone" of the electrical collection system. Appendix A Figure 8 is an illustration of a typical installation structure that will comprise the overhead collection system for the Wind Energy Facility. The plot plan provided as Appendix A Figure 4 shows a representation of the collection system layout. At Project interconnection substations, voltage from the collection system will he ncreased from 34.5 -kV to 230 -kV or 115 -kV depending on transmission line capacity and interconnection site. From the Project interconnection substation, the above -ground Mountain Breeze Transmission Facility (230 -kV) or Panorama Transmission Facility (115 -kV) will connect the Project to the substations at Junction S\\ itch Yard and Redtail Substation (or similar substation) respectively. interconnection Substations The Project substations will include breakers, switching and metering equipment, and a 34.5/230 -kV or 34.5/115 -kV step-up transformers, which will increase the voltage from the 34.5 -kV collection system to the Mountain Breeze Transmission Facility (230 -kV) or the Panorama Transmission Facility (115 -kV). Both project substations will interconnect at existing larger substations already connected to the regional Leeward Renewable Energy Development. LLC 5-11 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) electric grid. The Mountain Breeze Wind Energy Facility will interconnect to the Junction Substation (SF similar facility) via the Mountain Breeze Transmission Facility. The Junction Substation will be upgraded or expanded to accommodate the needs of the Mountain Breeze Wind Energy Facility. The Panorama Wind Energy Facility will interconnect to the existing Redtail substation (or similar facility) via the Panorama Transmission Facility. All existing substation upgrades and/or expansions are anticipated to occur within the existing approximately 7 -acre Junction Substation (or similar facility) footprint or approximately 5 -acre Redtail substation footprint. If upgrades and/or expansions cannot occur within existing footprints, then the substation owners (Tri-State for Redtail substation and Cedar Creek 1 for Junction) will amend their existing USRs. The substations will have graveled parking areas to accommodate maintenance vehicles. To prevent access to high -voltage equipment, the substations will be surrounded by chain -link security fencing. A locked vehicle gate will be located at the entrances to the main facility and the substations. Key boxes will be provided for emergency personnel. A detailed site plan for the substations will be provided prior to construction. Meteorological Towers The Project currently has 3 temporary 60 -meter meteorological towers. Leeward is requesting approval for up to three permanent meteorological towers at the Mountain Breeze Wind Energy Facility and up to three permanent meteorological towers at the Panorama Wind Energy Facility that will be up to 90 -meters in height and will remain in place to study and monitor wind resources for the Project during its operation. These permanent meteorological towers will be as tall as the hub height of the selected wind turbine(s) and will provide data critical to assessing the performance of the Project and aid in short-term forecasting for the Project. The permanent meteorological towers will comply with applicable FAA requirements. O&M Building The existing, currently permitted Cedar Creek 1 Wind Farm O&M building \\ ill he used for the Mountain Breeze and Panorama Wind Energy Facility. The O&M building includes offices, spare parts storage, kitchen, restrooms, and a maintenance shop area. Potable water is obtained from an on -site permitted well. Wastewater from the building will he discharged to an on -site currently permitted domestic septic tank and drain field. During operation of the Wind Energy Facility, Leeward will have between 15 to 20 part-time, full-time. or contractor employees (e.g., site manager, operations manager, and operating technicians) on site who will be responsible for operating and monitoring the facility, including coordination of all scheduled maintenance as well as forced outages and equipment malfunctions. Leeward staff includes Leeward Renewable Energy Development, LLC 5-12 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) approximately 30 part-time, full-time, or contractor employees that currently maintain Cedar Creek I. If required, Cedar Creek I will expand their existing facilities to accommodate the increase in operation employees. Cedar Creek I will seek the authorizations necessary for any expansions. The operating plan will include a schedule of outages to facilitate routine inspections and maintenance on the wind turbine generators. Inspection and maintenance activities will involve inspecting wear and tear on components such as seals, bearings, and bushings; lubricating the mechanical systems; and evaluating control systems. Temporary Facilities Other temporary facilities will be required for the construction phase of the Project, including two concrete batch plants, located in the vicinity of the Mountain Breeze and Panorama substations, laydown areas for an equipment and construction management facility, crane paths and working pads, and staging areas for turbine delivery. The laydown areas will include a construction trailer (Leeward will have 2-3 temporary construction trailers and their Balance of Plant (BoP) contractor will have 3-4 temporary construction trailers), sanitation facilities, and fencing for security and safety. Drinking water will be trucked in by the construction contractor in compliance with Chapter 14 of the Weld County Code. The temporarily affected areas will be restored to pre -construction conditions, to the extent practicable, after construction has been completed. Re -vegetation and seeding will be completed in accordance with specific landowner agreements and approved Weld County seed mixes. 5.6.4.2 Transmission Line Facilities The Wind Energy Facility will have up to two transmission lines, the Mountain Breeze Transmission Facility (230 -kV) and Panorama Transmission Facility (115 -kV). Mountain Breeze Transmission Facility will be approximately 11 -miles in length, and Panorama Transmission Facility approximately 15 -miles in length, both of which will be within a permanent 180 -foot right-of-way. The Mountain Breeze Transmission Facility will interconnect to Junction Switch Yard, ' ' , within the southwest portion of Cedar Creek I Wind Farm (see Interconnection Substation discussion above in Section 5.6.41.). The Panorama Transmission Facility will interconnect to Redtail Substation, or similar facility, (see Interconnection Substation discussion above in Section 5.6.41.). Leeward requests a permit for the 180 - foot ROWs to construct the Mountain Breeze and Panorama Transmission Facilities. Leeward will design and construct the Transmission Facilities. Leeward's engineers, construction personnel and contractors will develop transmission systems that are reliable, safe, and effectively maintained. Leeward's Project development will minimize adverse environmental effects, while maintaining the Project's schedule. Leeward Renewable Energy Development, LLC 5-13 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) The structure specifications of the Transmission Facilities will be finalized prior to construction; however, they will likely consist of H -frame and guyed three -pole structures as engineering needs dictate, and they may be wood or steel. The two -pole H -frame structures will be approximately 100 feet in height. The two poles of the H -frame structure will be 20 feet apart. At angles of greater than 5 degrees, or at other locations where engineering needs dictate, guyed three -pole structures will be used. Guyed H -frame structures will be used at angles of less than 5 degrees. Structures will have a weathering finish. The pole spacing will be approximately 100 feet depending on terrain, existing obstructions, and the type of pole utilized. Final design specifications will be provided to Weld County prior to the start of construction (Table 5-2Table 5 2). Appendix A Figure 8 illustrates potential structure types for the Transmission Facilities.

The laydown areas will be located near an existing road and on previously disturbed areas to the extent practicable. One laydown yard will be located at each of the wind facility substations and the remaining . Final laydown yard locations will be are identified on ' Figures 2-2 and 2-3 located in Appendix A of this Application. Temporary facilities related to the Transmission Facilities will be restored to pre -construction conditions upon completion of construction. No permanent employees will be necessary for the Transmission Facilities. Preventative maintenance for the Transmission Facilities will include routine ground patrols. The purpose of patrols is to detect equipment requiring maintenance, repair, or replacement. In addition to regular patrols, special patrols are Leeward Renewable Energy Development, LLC 5-14 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Table 5-3: Representative Estimates for Impacts from the Wind Energy Facilities Project Facilities Description of and Approximate Acreage of Impacts Impacts Permanent Impacts Temporary Turbines Circular acre disturbance turbine site with 3- impact Each pedestal gravel around turbine ring it. is having approximately The of base 20 a total is diameter feet above set placed atop 0.08 -ground of a concrete 20 circumferentially acre. feet permanent and a turbine impacts 420 acres 11.2 acres Total Access roads 20 associated of -24 access -foot -wide with roads impacts construction roads gravel will surface be approximately 16-20 feet The wide Total access impacts road 242-291 acres 194-242 acres Collection lines A impact estimated used lines 50 -foot to corridor install construction for the the has equipment collection been impacts installation exception associated are of above all with temporary ground collection in junction nature, line with boxes the line collection impacts 606 acres <1 acre Total Meteorological (METS; Circular acre disturbance tower site with 0.75- Assumes fenced in area of 50 feet by 50 feet Towers permanent) MET tower 4.5 acres <1 acre Total impacts New Substations 20 acres acre switch a gravel site. yard pad up substation to will 10.0 acres be within constructed the 20 - The on substation new impacts 40 acres 10 acres Total Laydown 4) batch and concrete plants yards (2) (2- combination to six facilities 40 of acres. these will be associated construction.

The acreage of the permanent footprint of the facility (e.g., roads, turbine foundations, substations, O&M building, etc.) will be up to approximately 2,100 acres or less the 5 percent of the total site. Total acreage of the Mountain Breeze Transmission Facility ROW is up to approximately 240 acres of transmission line ROW. Total acreage of the Panorama Transmission Facility ROW is up to approximately 330 acres of transmission line ROW. For analysis purposes to provide flexibility for engineering design and sensitive resources avoidance, Leeward analyzed a 500 -corridor for the transmission. 5.6.10 Existing Land Use (21-3-330.B.5.1) Wind Energy Facility The existing land use within the Wind Energy Facilities is agricultural, including a mix of dryland farming and grazing, see Appendix A Figure 5. Residential buildings and outbuildings are scattered in low density throughout the Wind Energy Facility ,. There are adjacent lands to the lease lands included in the Wind Energy Facilities that area owned by U.S. Forest Service, Pawnee National Grasslands and U.S. Department of Defense (DOD; missile silos); these lands are not part of the Mountain Breeze and Panorama Wind Energy Facility. Land enrolled in the CRP program will maintain CRP status, with the exception of the permanent disturbance within the turbine tower and new access road footprints, which will either comply with allowed exclusions to the CRP program or will be withdrawn from the program with compensation paid to landowners by Leeward for lost CRP payments. Producing and abandoned oil and gas wells are shown on Appendix A Figure 6. No impacts to oil and gas wells will occur based on the indicative layout of the Wind Energy and Transmission Facilities. Current technology also allows access directionally further reducing the likelihood of impacts to these operations. In designing and micrositing the Wind Energy Facility. Leeward will comply with setbacks regarding placement of the wind turbines to provide adequate buffers to adjacent land uses. Table 5-6Table 5 6 provides a list of setbacks which Leeward will be committed to for the Wind Energy Facility. Leeward Renewable Energy Development, LLC 5-27 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 2. Construction timing constraints to avoid breeding seasons for certain species in some areas or for certain activities. 3. Additional study of potential impacts and species reaction to presence of the Wind Energy Facility. Prior to applying for building permit applications, final locations for facility components and final mitigation measures will be determined. Water bodies and wetland resources within the vicinity of the Project include intermittent and ephemeral streams and drainages, artificial paths, and small unnamed ponds. These occur in areas of low topography where surface run-off typically collects. These locations are not compatible with the desired locations for wind turbines, which are typically placed in areas of higher topography to capture the higher wind speed and density. Preliminary desktop assessment and mapping of the lakes, wetland resources. and features that could be considered for designation as "waters of the U.S." was conducted. According to mapped NWI and NHD datasets there are no waters of the U.S. located in areas with proposed facilities. All facilities associated with the Project have been sited to avoid or minimize impacts to these important resources. Field verification will be completed prior to construction for all areas with proposed facilities and where wetland and water body resources may occur to mini m i 7e impacts to water resources. If needed, Leeward will obtain the appropriate Nationwide Permit from the U.S. Army Corps of Engineers. There are no known socioeconomic constraints associated with the proposed Project. Transmission Facilities Based on criteria listed in Section 3 above, the Preferred Alternative for each of the Transmission Facilities was selected as shown on Appendix A Figure 2-1. The proposed routes minimally impacted area buildings and residences as well as the existing Cedar Creek I Wind Farm turhine arrays. Transmission facilities have been developed to minimize impacts to sensitive natural and human resources. Data for cultural, water, wildlife, ecology, and other resources was applied when the Transmission Facility locations were sited. Areas of sensitive habitats, water bodies, and wetlands have been avoided where possible. A number of golden eagle nests have been identified within the 10 -mile aerial survey area completed by Leeward in the spring and early summer of 2017 and 2018. To minimize disturbance to sensitive species, Leeward is working closely with USFWS and CPW to develop the Project facilities, protect important habitat and minimize impacts to species. Leeward Renewable Energy Development. LLC 5-31 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) There are no known socioeconomic constraints associated with the Project. The final Transmission Facility routes will follow the proposed indicative route as closely as possible but may be shifted based on the ability to acquire right-of-way easements from landowners. The final Transmission Facility routes and engineering details will be provided to Weld County prior to construction. The final Transmission Facility routes will avoid and minimize impacts to environmental and community resources. 5.8 Natural and Socioeconomic Environmental Impacts from Construction of the Wind Energy Facility (21-3-330.B.7) This section describes the impacts of the proposed Project on various environmental resources in Weld County and addresses the applicable requirements of 21-3-330 of the Weld County 1041 Regulations. For purposes of analyzing environmental impacts in this application, the Project Area is defined as the area within the Wind Energy Facility and Transmission Facilities that will be disturbed by construction, as shown on Appendix A Figure 2-1. 5.8.1 Land Use Existing land uses will continue uninterrupted for the majority of the land within the site boundary for the Wind Energy Facility and Transmission Facilities. Permanent impacts anticipated will include less than I percent of the Project area. Temporary impacts will include less than 5 percent of the Project area. Impacts will include footprints of turbines, access roads, substations, structures for the Transmission Facilities, and the collection system structures. Agricultural productivity will be minimally impacted as farming and grazing activities may continue up to the base of the wind turbines. Land use along the proposed Transmission Facilities will be minimally impacted and will continue to include a mix of agricultural and residential uses. Minimal effects to agricultural productivity will occur as a result of the Project. Further discussion of the impacts of the proposed Project on land use, including conformance with Land Use Plans, agricultural lands, use of existing ROW can be found below in Section 5.9.1. 5.8.2 Vested Water Rights No additional water rights are anticipated for the Project for this decision. The existing and permitted Cedar Creek I O&M building is the only anticipated facility requiring an on -site water well for long-term water supply. The volume of water use for the O&M building will be similar to the volume of a residence with water used for drinking, showering, toilets, etc. Leeward plans to use the existing Cedar Creek I O&M facility for O&M of the proposed Mountain Breeze and Panorama Wind Energy Facility. Any necessary expansion of the existing Cedar Creek I facility will be addressed by Cedar Creek I. Leeward Renewable Energy Development, LLC 5-32 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest - Application Requirements (21-3-330) Existing land uses will continue uninterrupted for the majority of the land within the site boundary for the Wind Energy and Transmission Facilities. Table 5-3Table 5 3 and Table 5-4Table 5 '1 provide anticipated permanent and temporary impacts which include footprints of turbines, access roads, substations, structures for the Transmission Facilities, and the collection system structures. Agricultural productivity will be minimally impacted as farming and grazing activities may continue up to the base of the wind turbines. Land use along the proposed Transmission Facilities will be minimally impacted and will continue to include a mix of agricultural and residential uses. During construction, water for the concrete batch plants, dust control, and drinking water will be obtained by the construction contractor from existing, permitted sources. Leeward will comply with all local, state, and federal permitting requirements and water rights processes regarding development and use of existing. permitted water sources. 5.9.1.1 Conformance with Land Use Plans The Weld County Code, Chapter 22, Comprehensive Plan, has been reviewed and the proposed wind farm is consistent with the intent of the Comprehensive Plan, including Land Use, Environmental Resources, and Natural Resources. The proposed wind farm supports Weld County's Alternative Energy Resources Goals and Policies (Sec. 22-5-140) and is consistent with the Economic Development Goals and Policies (Sec. 22-6-20). The current use of the site and the surrounding area is dryland farming, grazing and CRP land. The proposed use will not compromise the goals of agricultural land use or any other land use category. The Project will not impact effective and efficient delivery or place undue strain on adequate public facilities and services or other land use amenities. Areas of sensitive natural environments, including riparian areas, water bodies. and areas of potentially suitable habitat for threatened and endangered species are not prevalent on the proposed site for the wind energy facility. Impacts to environmental resources such as air, water, waste, noise, and public health will be minimal. Mitigation practices will minimise impacts from dust generation and waste products. An erosion control/stormwater management plan will be developed and implemented to prevent or minimize sediment entry to the drainages within the overall Project Area. During construction. vegetation may be removed and much of it will be reclaimed once the construction period is complete, a small amount of the Project will he subject to permanent impacts as shown in Table 5-3Table 5 3 and Table 5-4Table 5 /1. Similarly, wildlife ma) he temporarily displaced during construction but will be able to return to the site once the construction period ceases. Leeward Renewable Energy Development, LLC 5-34 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.13 Structural Alternatives (21-3-330.B.11) The dependency of a wind energy facility upon consistent wind speeds and appropriate topography determines the location of the Wind Energy Facility. Alternative types of energy generation facilities such as coal or natural gas are not considered as renewable resources and will not meet the objective associated with Amendment 37. Leeward considered feasible transmission line alignments and ultimately proposed an alignment that was economically sound and environmentally compatible with existing environmental conditions. The alignment also is compatible with future Weld County land use plans and acceptable to the jurisdiction it crosses. The proposed routes for the Transmission Facilities are located entirely in Weld County as shown in Appendix A Figure 2-1. The final transmission line routes will be provided to the County after final design is complete and prior to construction. The proposed route for the Mountain Breeze Transmission Facility will include approximately 11 miles of new single circuit 230 -kV transmission line construction and the Panorama Transmission Facility will include approximately 15 miles of 115 -kV transmission line construction. Both facilities will transmit power from the Project to the proposed interconnection sites at Junction Switchyard and Redtail Substation or similar facility. The ROW for the Transmission Facilities is 180 feet. The Transmission Facilities will cross numerous unnamed intermittent and ephemeral drainages. The routes were selected based on land acquisition issues and engineering and design goals. in general, areas of sensitive natural environments, including riparian area, water bodies, and areas of potentially suitable habitat for threatened and endangered species or species of concern will be avoided where possible. 5.14 Air and Water Pollution Impacts and Control Alternatives (21-3-330.B.12) 5.14.1 Air Pollution Impact and Control Weld County responds to air quality complaints through funding and authority from CDPHE which enforces state air quality regulations. in general, the primary sources of air emissions in Weld County include oil and gas exploration and productions, highway vehicles, biogenic sources, non -road mobile sources, construction and road dust, agriculture and other point sources (CDPHE, 2013). in 2013, there were 597,133 tons of air emissions in Weld County from all sources which equaled 17.7 percent of all sources of emissions in Colorado.

Leeward Renewable Energy Development, LLC 1-5 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Approach to Site Selection 2.0 APPROACH TO SITE SELECTION 2.1 Wind Energy Facility The Project Area was selected based on several key developmental factors that include, but are not limited to, the wind resource in the area, environmental consideration for appropriateness, transmission characteristics, and economic considerations. Colorado is a leading state in wind energy generation in the United States, including Weld County in particular. An assessment of wind speed was initiated on the neighboring Cedar Creek I Wind Farm, located adjacent to the west and south of the Project, in 1996 by the U.S. Department of Energy's Utility Wind Resource Assessment Program (U WRAP) to evaluate potential sites in Colorado. Of the 10 sites evaluated, the Cedar Creek I site had the highest average documented wind speed and it was determined the predominant winds coming from the northwest experience an increase in velocity as they encounter the hills that lie perpendicular to the winds. In addition, the National Renewable Energy Laboratory (NREL) Colorado 80 -Meter Wind Resource Map shows modeled average annual wind speed at 80 meters within the Project Area at 7.0 to 8.0 meters per second (m/s) (U.S. Department of Energy, 2010). Areas with annual average wind speeds around 6.5 meters per second and greater at 80-m height are generally considered to have a resource suitable for wind development. Leeward has been studying wind resources within the Project Area for 15 years and currently has three temporarily permitted 60 -meter met towers in the Project Area. This application requests authorization to construct up to 6 permanent met towers at approximately hub height. When operational, the Project will have a total of three permanent met towers at the Mountain Breeze Wind Energy Facility and three permanent met towers at the Panorama Wind Energy Facility. Two new substations will be required in order to centralize the power generated by the turbines then transport it offsite. In each case, the project -specific substation was centrally sited and will accommodate the turbine generation in that project area, as shown in Appendix A Figure 2. 2.2 Public Involvement Public involvement during the development stage of the Project helps identify the concerns related to the Project and is one of the most important factors in the energy facility siting process. Input from jurisdictions, agencies, and landowners has become a major focus in siting new utility and generation facilities. Public outreach and agency correspondence are included in Appendix B. To obtain the public's input, Leeward has conducted the following meetings: Leeward Renewable Energy Development, LLC 2-1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Approach to Site Selection • Leeward conducted a survey with private landowners near the existing Cedar Creek Wind facilities and near the proposed Project Area in November 2017. Leeward used the survey to gauge how well they have functioned within the local community as a wind operator. Leeward also assessed how receptive the local community was to additional wind facilities. The survey results were positive and supportive overall of Leeward and the additional wind facilities. • Leeward participated in a Pre -Application Meeting with the Weld County Department of Planning Services, including the Public Works, Health, Building, and Engineering Departments on November 16, 2017 at the Greely Administrative Offices. The purpose of the meeting was to address issues that Leeward should address in this 1041 Permit Application. A Pre -Application Review Request was submitted to Weld County Department of Planning Services on September 25, 2018 and a second pre -application meeting was held with the Weld County Department of Planning Services on October 18, 2018 (see Appendix B). • Agency outreach letters were mailed to 11 agencies, including Colorado Parks and Wildlife (CPW); Colorado Office of Archaeology and Historic Preservation (COAHP); Warren Air Force Base, Wyoming; U.S. Fish and Wildlife Service (USFWS); Colorado Ecological Services, Kimball County, Nebraska; Pawnee Fire Protection District; Nebraska Highway Superintendent; U.S. Forest Service (FS) — Pawnee National Grassland; New Raymer — Stoneham Fire Protection District, U.S. Army Corps of Engineers (USACE), and Laramie County, Wyoming Planning & Development Office. Response have been received from the Laramie County, Wyoming Planning & Development Office, Warren AFB, U.S. Army Corps of Engineers, and Pawnee National Grasslands. Copies of the correspondence are included in Appendix B. • Leeward has and continues to coordinate with several agencies as necessary and interest warrants. Coordination generally has included telephone and email correspondence. However Leeward has participated in several in -person meetings with USFWS and CPW as they have worked on developing the Project. • Leeward held an open house in Grover, Colorado at the Pawnee School Multipurpose Room, on October 2, 2018. There were 76 participants invited to the meeting, which included all landowners within 0.25 mile of the Project Area in Colorado. At this open house, all attendees were asked to fill out comment cards regarding their concerns and the only comment received was supportive of the Project. Appendix B provides a list of materials presented at the public open house and comments that were received. Leeward Renewable Energy Development, LLC 2-2 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Approach to Site Selection 2.3 Economics Leeward has an obligation to both its shareholders and customers to operate in a financially responsible manner. The Project provides the opportunity to commercialize one of the best wind resources in the state contributing to the renewable energy demand in the region. Furthermore, this Project will sell power to the regional utility, under a long-term Power Purchase Agreement (PPA). Leeward has entered into a long-term PPA on the Mountain Breeze Wind Project and is developing a long-term PPA(s) opportunity for the Panorama Wind Project. A summary of the Mountain Breeze Wind Energy Facility PPA is included in Appendix C. 2.4 Environmental Considerations Leeward evaluated a variety of environmental criteria during the siting process that included a review of existing wildlife habitat information, sensitive vegetation communities, water resources, culturally sensitive areas, and other resource concerns. Leeward has completed over a decade of environmental surveys and monitoring at their adjacent Cedar Creek I facility. This included several years of avian, bat, and other wildlife surveys. Recent environmental surveys for this Project included mapping of black - tailed prairie dog colonies to understand prey base for golden eagles in 2018, and 2 full years of raptor nest surveys during 2017 and 2018. Currently, Leeward has followed USFWS's Land -Base Wind Energy Guidelines (2012, WEG) and incorporated the results of their wildlife, wetland, and cultural studies into the project development. Facilities are sited to minimize impacts to identified resources. Leeward will continue to follow WEG and will incorporate their findings into Project development and operations where possible. Additional surveys will be conducted, as required, by Weld County and other regulatory requirements prior to construction. 2.5 Engineering Leeward's meteorologists and engineers are responsible for identifying the location of each individual wind turbine along with the associated access roads, power collection system, and other associated facilities within the proposed Project. Leeward plans to hire a professional engineering and construction company to design the foundations, roads, and substation facilities to ensure the Project is built safely, to code requirements, within budget, and scheduled timeframes. Engineering input is vital to ensure that construction and operation are reliable and safe, and that the facility can be effectively maintained. Engineering input is also important in minimizing adverse environmental effects, maintaining schedules, and meeting budget requirements. Leeward Renewable Energy Development, LLC 2-3 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Approach to Site Selection 2.6 Acquisition of Land Rights Obtaining the necessary land rights for access, construction, operation, and maintenance of the wind energy and transmission line facilities is required when siting new facilities. The land rights associated with the Project are in the form of a land lease and wind easement and transmission line agreements, therefore, the fee ownership does not change. Leeward has negotiated with landowners within the boundary of the Project to acquire the land rights necessary for construction and operations of the Project. Leeward currently has 100 -percent of the Mountain Breeze Wind Energy Facility leased and 100 -percent of the Panorama Wind Facility leased. Similarly, Leeward currently has 95 -percent of the Mountain Breeze Transmission Facility leased and 95 -percent of the Panorama Transmission Facility leased. The land leases that have been executed are recorded in Weld County, Colorado (see Appendix E for copies of existing Short Form Agreements of Land Leases and Wind Easements). Any outstanding leases that remain at the filing of this application will continue to be negotiated in good faith. All land will be under lease and copies of the lease agreements will be provided to the Weld County prior to construction. Leeward Renewable Energy Development, LLC 2-4 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Transmission Facilities 3.0 TRANSMISSION FACILITIES Two new interconnection transmission lines, approximately 15- and 11 -miles in length (Transmission Facilities) will be required to export the electric power generated at the Project. Both transmission line corridors were selected based on general locations for the Wind Energy Facility and on -site requirements, engineering, and electric system planning needs. The interconnection transmission line associated with Mountain Breeze Wind Energy Facility will be approximately 11 -miles long and 230 -kilovolts (kV), connecting to Junction Switch Yard or similar facility (Mountain Breeze Transmission Facility). The Mountain Breeze Transmission Facility analyzed three alternative alignments, these alternatives are shown in Appendix A Figure 2. The Preferred Alternative was selected based on interconnection considerations, land acquisition considerations, avoidance of environmental resources, and avoidance of other facilities (military and utilities) and is presented in the remainder of this application for analysis and request for approval from Weld County. Part of the transmission line will traverse lands which are currently part of the Cedar Creek Wind Energy Projects. Sub -easement agreements will be in place with the Cedar Creek Wind Energy Projects where required. The interconnection transmission line associated with Panorama Wind Energy Facility will be approximately 15 -miles long and 115 -kV, connecting to Redtail Substation or similar facility (Panorama Transmission Facility). The Panorama Transmission Facility analyzed two alternative alignments and these alternatives are shown in Appendix A Figure 2. The Preferred Alternative was selected based on interconnection considerations, land acquisition considerations, avoidance of environmental resources, and avoidance of other facilities (military and utilities) and is presented in the remainder of this application for analysis and request for approval from Weld County. Part of the transmission line will traverse lands which are currently part of the Cedar Creek Wind Energy Projects. Sub -easement agreements will be in place with the Cedar Creek Wind Energy Projects where required. Mountain Breeze and Panorama Transmission Facilities were determined based on the following criteria: • Shortest length between the proposed Project and the existing substation • Buffers surrounding the existing Cedar Creek I and Cedar Creek 11 turbines • Buffers surrounding existing buildings and residences • Buffers surrounding military infrastructure • Coordination with Colorado Parks and Wildlife to avail sensitive wildlife species Leeward Renewable Energy Development, LLC 3-1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Transmission Facilities The Mountain Breeze and Panorama Transmission Facilities locations are shown in Appendix A Figure 2. The routes were sited to have minimal impacts to area buildings and residences as well as to the existing Cedar Creek I and Cedar Creek H Wind Farm turbine arrays. To date, all easements along the routes have not been acquired. Leeward requests the ability to slightly modify the routes based on final Project design and easement acquisition. Final route easements and specific engineering design will be provided to Weld County prior to Project construction. Leeward Renewable Energy Development, LLC 3-2 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Wind Energy Basics 4.0 WIND ENERGY BASICS The basic components of a wind energy facility include the turbines, foundations, power collection system, and roads. Wind energy production includes the following five basic components, which are also shown in Appendix A Figure 2. 1. Electrical Power Generation — Wind blowing against the turbine blades causes the blades to rotate, which in turn rotates electrical generators that produce electricity. 2. Energy Transfer — The generated electricity is fed through cables within the tower to a base panel at ground level inside the tower. The electricity is then fed to a pad -mounted transformer located adjacent to the tower that increases (steps up) the power to a higher voltage of 34.5 -kV. 3. Collection System — The stepped -up power from the transformer is fed into a collection system. Power collection lines connect groups of wind turbines in the field to a substation. 4. Substation — At the substation, the voltage is increased to the same level as the utility grid so that it can be fed into the electrical transmission system. For the proposed Project, the voltage will be increased to 230 -kV for the Mountain Breeze Project and 115 -kV for the Panorama Wind Project. 5. Utility transmission — Electrical energy is sent through the transmission lines to utility distribution systems for delivery to customers. Two transmission lines, Mountain Breeze Transmission Facility, approximately 11 miles in length, and Panorama Transmission Facility, approximately 15 -miles in length, will interconnect the Project to the electric grid for delivery to customers. The Mountain Breeze Transmission Facility will tie into Junction Switch Yard or similar substation and Panorama Transmission Facility will tie into Redtail Substation or similar facility.

Leeward Renewable Energy Development, LLC 5-3 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.3.1 Surface Landowners (21-3-330.B.2.a) The names and addresses of all surface property owners within 1,320 feet (0.25 mile) of the Wind Energy Facility boundaries proposed to be physically disturbed are provided in Appendix D. The names and addresses of all surface property owners within 500 feet on either side of the centerline of the proposed alignments for the Transmission Facilities are also provided in Appendix D. 5.3.2 Access to the Proposed Site (21-2-330.B.2.b) Land leases and wind and transmission line easement agreements have been negotiated with landowners within the site boundary of the proposed Wind Energy Facility. An abbreviated version of this lease agreement (called Short Form Agreement of Land Lease and Wind Easement) has been recorded in Weld County and copies are provided in Appendix E. Access to the Wind Energy Facility will be on existing roads and newly constructed roads as necessary to access the Project. Access to the rights -of -way (ROWs) for the Transmission Facilities will occur primarily along existing roads or via overland access. New roads will be built only when necessary for construction or maintenance purposes. Existing private roads, county roads, and state highways will be used to access the transmission facility ROWs. 5.3.3 Real Property Interests (21-3-330.B.2.c) The 180 -foot wide easements containing alignments for the Transmission Facilities will be purchased from landowners in the form of a ROW agreement. A list of ROW easement agreements acquired as of application submittal is included in Appendix E. Remaining agreements, including agreements with interest holders (except mineral interests) will be obtained through good faith negotiations prior to construction. Leeward currently has 95 -percent of the Mountain Breeze Transmission Facility leased and 95 -percent of the Panorama Transmission Facility leased. A list of interest holders and utility companies in the area is included in Appendix D and Appendix F respectively. Leeward will obtain all necessary crossing permits from Weld County, interest holders, and utility companies for ROWs and facilities crossed prior to construction. 5.3.4 Mineral Interests (21-3-330.B.2.d) Mineral estate owners were identified by outside counsel pursuant to the requirements of C.R.S. §§ 24- 65-101 et seq ("Statutes"). The Statutes were reviewed and the offices of the Weld County Assessor and Weld County Clerk and Recorder were consulted by outside counsel (initially on October 15, 2018 and for confirmation on Leeward Renewable Energy Development, LLC 5-4 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) October 25, 2018) regarding the process for identifying mineral estate owners as described in the Statutes and within the Project Area. On October 16, 2018, outside counsel searched the Clerk and Recorder records from 1995 (even though this date pre -dates the Statutes, searches were started then for completeness) through October 16, 2018 for the Statutory notice request forms. Identified forms were downloaded, and the pertinent information was added to a notice spreadsheet based on the location of the pertinent property within the Project Area. Assessor Searches also were performed by outside counsel on October 16, 2018. All identified mineral estate owners were added to the notice spreadsheet. The initial searches were repeated to ensure accuracy. The process employed, and discussed above, was further discussed by Applicant and outside counsel with the Weld County Department of Planning Services on October 18, 2018 and by outside Counsel with the Weld County Attorney's office on October 24, 2018. Further, the Weld County Department of Planning Services provided the required form of certificate for Statutory notice on October 18, 2018, and outside counsel confirmed this form with the Weld County Attorney's Office on October 24, 2018. The searches were repeated on December 21, 2018 by a separate lawyer. The names and addresses of the mineral estate owners identified in the searches are listed in Exhibit A to the certificate attached to this application as December 28, 2018 (see Appendix D). Searches will be repeated and verified to ensure accuracy and notices given as required by the Statutes and by applicable County rules. Further, and related to potential mineral issues, Applicant and outside counsel have reviewed Colorado Oil and Conservation Commission (COGCC) information and consulted with the COGCC regarding the Project Area. On October 17, 2018, Applicant downloaded COGCC GIS data and mapped this data in the Project Area for the purpose of identifying any active or permitted wells in the Project Area. No active wells were identified, and the permits for any wells in the Project Area were at that time expired. Also, on November 1, 2018, outside counsel contacted the COGCC and reviewed the COGCC's webmap with a COGCC representative for the purpose of confirming the October 17, 2018 review. In all, Applicant and outside counsel confirmed no active mineral development or permitted mineral development in the Project Area. Further, and for the purpose of assessing potential issues, historical spacing orders for the Project Area were identified and reviewed by outside counsel on September 24, 2018, and these orders were later discussed with the COGCC. From this review, Applicant confirmed, based on the historic Project Area Leeward Renewable Energy Development, LLC 5-5 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) spacing rules and potential layouts, that more than sufficient land exists for both mineral and wind development, with limited if any interference between the two operations. 5.4 Section 1041 Permit Maps (21-3-330.B.3) 5.4.1 Vicinity Map Requirements (21-3-330.B.3.a - d) The Section 1041 Permit Vicinity Map (Appendix A Figure 3) is included in this application in a reproducible format. This map includes a vicinity view of the Project as shown on one sheet at a 1:54,000 scale. The permit map is consistent with the requirements of Section 21-3-330.B.3 and the relevant subsections. 5.5 Plot Plan (21-3-330.B.4) Appendix A Figure 4 provides a plot plan for the Project, including the Wind Energy Facilities and Transmission Facilities. The plot plan provides a layout of the Wind Energy Facilities, showing an indicative layout of turbines, electrical collection systems, and substations/facility areas. The collection system shown on Appendix A Figure 4 is only intended to show the connection between the disconnected turbine corridor segments, not the entire collection system. Turbine corridors are generally arranged in a northeast -southwest orientation, perpendicular to the primary wind direction, which is from the northwest. The indicative centerline and width of the Transmission Facilities are also included in Appendix A Figure 4. The wind resource assessment and engineering design of the Wind Energy Facilities is ongoing; therefore, the site layout is considered indicative and subject to micrositing changes. The final number of wind turbine generators and the number and location of turbine strings, access roads, and collection systems will be finalized based on the final wind turbine machine, but it will not exceed 140 turbines. Final micrositing of the Transmission Facilities is also ongoing and will result in minor changes to the final transmission facility alignments. Final transmission facility alignments will not exceed the estimated 11 -miles of 230- kV transmission line for the Mountain Breeze Transmission Facility and 15 -miles of 115 -kV transmission line for the Panorama Transmission Facility. Leeward is committed to complying with all local, state, and federal requirements for protecting sensitive environmental areas (wetlands, nesting areas, etc.) and cultural/archaeological resources. Once the design and layout are finalized, Leeward will submit final site plans showing detailed locations for all facilities as part of its building permit application and prior to construction. Leeward Renewable Energy Development, LLC 5-6 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.6 Other Information (21-3-330.B.5) The following sections outline additional items and information required in this application. 5.6.1 Present Use and Zoning (21-3-330.B.5.a) The Project Area is zoned Agricultural. This zoning classification is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production without the interference of other, incompatible land uses. There are no overlay zones applicable to the Wind Energy Facility area. The area is used for dryland farming and grazing. Several portions of farmland in the Project Area have been entered into the Conservation Reserve Program (CRP) under the U.S. Department of Agriculture's Farm Service Agency (FSA). If CRP lands are disturbed by the Project and it becomes necessary for them to be removed from CRP, then Leeward will compensate landowners for the lost CRP payments. In the CRP areas, the groundcover remains fallow and contains a mix of native prairie and invasive species. Other uses within the site include scattered residential properties and dispersed recreation such as hunting. Appendix A Figure 5 summarizes land use and cover within the Project Area. 5.6.2 Map Extent (21-3-330.B.5.b and 21-3-330.B.5.d) Appendix A Figure 11 provides the area within 10 miles from the Wind Energy Facility, as called for in 21-3-330.B.5.b.i for proposed power plant facilities. Appendix A Figure 11 also provides the area within 5 miles of the Transmission Facilities as required in 21-3-330.B.5.d. 5.6.3 Existing Transmission Lines and Pipelines and Other Major Facilities of a Public Utility (21-3-330.B.5.b(ii)) Appendix A Figure 6 provides utility information gathered to date from utility companies with infrastructure in the area. Appendix F contains a preliminary list of all utility companies that potentially have easements within the Project Area. These companies will be contacted by phone and/or by letter prior to final design of the Project. Appendix A Figure 6 shows all existing transmission lines of 115 -kV or greater for a distance of 2 miles beyond the identified Transmission Facility alternatives. Data gathered to date show that there are 2 transmission lines (115 -kV and above) within the two-mile vicinity of the identified Mountain Breeze and Panorama Transmission Line Facility alternatives. Leeward Renewable Energy Development, LLC 5-7 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.6.4 Type of Facility (21-3-330.B.5.e) The elements of the Project include up to 140 wind turbines, access roads, electrical collection lines, substations, two transmission lines, an existing O&M facility, and associated supporting infrastructure and facilities. The Project also includes the following temporary construction facilities: concrete batch plant areas, staging and parking areas, and a construction office trailer complex. 5.6.4.1 Wind Energy Facility Wind Turbines Wind turbines convert the kinetic energy of the wind into the rotational energy of a rotor and drivetrain. This energy is in turn converted into electrical power by industrial generators integrated within the wind turbine housing. An automated `pitch' system will control the speed of the rotor by turning the face of each rotor blade into or out of the wind. Modern wind turbines typically produce energy in a wind speed range of 3.1 to 25 meters per second or 7 to 56 miles per hour (mph). Power quality will be further accomplished through the use of power electronics, which convert generator output to achieve required output voltage and frequency control. An integrated wind speed and direction monitoring system works with a 'yaw' motion control system to keep the face of the turbine presented into the wind. Leeward intends to use a GE 2.X platform turbine models for the Mountain Breeze Wind Project. The final model selected will be based on availability and the highest compatibility with the site requirements (i.e. cost efficiency, manufacturers' availability, optimization of wind, land resources setbacks, environmental concerns, etc.) will be provided to the County as a condition of approval. The wind turbine output possibilities for this Project will range from 2.3 -MW to 5.8 -MW. The Wind Energy Facility layout is designed to accommodate any of the wind turbine output possibilities. Appendix K provides representative wind turbine models under consideration for the Project. Table 5-1 is representative of the wind turbine options under consideration; however, the Project may opt to use a wind turbine or combinations of wind turbines not included in the list. Leeward Renewable Energy Development, LLC 5-8 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Table 5-1: Representative Wind Turbine Type Characteristics for the Project Characteristics Turbine Options Under Consideration Wind turbine type GE 2.x — Vestas 4.2 Rotor diameter in meters (feet) 127 (417) 150 (492) Rotor swept area in sq. meters (sq. feet) 12,668 (136,357) 17,663 (190,020) Rated power (MW) 2.3 to 2.8 5.8 Cut -in wind speed (m/s) 3 3 Cut-out wind speed (m/s) 30 25 Blade length in meters (feet) 63.5 (208) 68 (233) Hub height in meters (feet) 88.6 (291) 105 (345) Highest blade height in meters (feet) 152.1 (499) 173 (568) While the turbines above are an example of probably turbines the industry is quickly moving towards greater size turbines in output and it could be potentially feasible at the time of construction to utilize a turbine with each generator reaching the capacity of 6 MW each. The maximum nominal rotor diameter under current consideration is 150 meters (492 feet). The rotor consists of three blades mounted to a rotor hub. The hub is attached to the nacelle, which houses the generator, brake, cooling system, and other electrical and mechanical systems. The towers on which the nacelle is mounted, will be constructed of conical tubular steel, with a hub height range from 80 to 105 meters (262 to 345 feet). All tower welds will be performed according to specifications established by the American National Standards Institute (ANSI). Surfaces of the tower components will be sandblasted and coated by the manufacturer to protect against corrosion. A secured door at the base of the tower will provide internal access to the turbine. Each wind turbine tower will sit atop a concrete foundation. Foundation size and design will be finalized once geotechnical analyses have been completed and the wind turbine model selected, though it is estimated the excavated area for the turbine foundation will be approximately 65 feet in diameter (approximately 0.0708 acre) (see Appendix A Figure 7, Turbine Foundation Example). During construction, a larger area (approximately 3 -acre area) may be used to lay down the rotors and maneuver cranes during turbine assembly. Lightning and ground protection for all wind farm equipment is designed and constructed to be compliant with all applicable National Electrical Code (NEC) and National Electric Safety Code (NESC) requirements. Grounding and shielding components are integrated into the foundation and structural elements of all equipment and conductor lines. In particular, each wind turbine will include conductive elements in the blades and a complete grounding and shielding network within the wind turbine, tower, and foundation. Leeward Renewable Energy Development, LLC 5-9 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Regardless of the specific model of wind turbines selected for the Project, the wind turbines will be white or light gray, similar to all of the other commercial -scale wind turbines currently operating in eastern Colorado. Wind turbines will be sited and lit to satisfy minimum Federal Aviation Administration (FAA) requirements. The preliminary indicative wind turbine locations include approximately 7 alternate locations (depending on the final turbine model selected) in the event that a proposed wind turbine location becomes impractical or impossible to build. Changes to the wind turbine layout may be caused by a variety of reasons, such as geotechnical conditions, environmental conditions, wildlife habitat, archeological resources, landowner requirements, or others. For these reasons, the turbine layout is included as an indicative layout (Appendix A Figure 4). The indicative layout has been developed based on Weld County Code requirements (i.e. setbacks and others), desktop studies, and field studies. Leeward's site layout has incorporated the results of: WEG siting and pre -construction recommendations; OAHP cultural record research; USFWS IPac threatened and endangered species database research; CWP natural heritage record research; NWI wetland data; FEMA floodplain data; and many other data sources. In addition to all the desktop and field research incorporated into Leeward's layout, agency input from CPW, USFWS, ACOE, fire districts, U.S. Air Force, U.S. Forest Service, and others have been incorporated into Leeward's layout. The final layout will account for all the data used to develop the indicative layout, the results of micrositing, as well as final turbine model, surveyed coordinates of all proposed wind turbines will be submitted to Weld County prior to start of construction, and an as -built drawing will be submitted at the end of construction, which will include road names and wind turbine numbers within the Project Area. A number of setback requirements have been developed and will be observed in final placement of the wind turbine towers as indicated in Section 5.6.10. A sign may be included at or near the entrance to the Project, which location is yet to be determined. Any such sign will adhere to Weld County requirements for placement of signs (Article IV, Division 2, Chapter 23, and Appendices 23C, D, and E), or a separate variance will be requested from Weld County. The sign will be unobtrusive and conform to the style of the surrounding area. Access Roads The final layout of the Wind Energy Facility will minimize the need for new, permanent roads within the Project Site through the use of existing access roads and county roads wherever possible. New roads within the Project Site will not be accessible to the general public. The new access roads will be designed and constructed similar to the existing Cedar Creek I Wind Farm road network and in accordance with Weld County regulations and requirements. Improvements such as construction of wider shoulders to Leeward Renewable Energy Development, LLC 5-10 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) facilitate crane travel and turning radii to facilitate deliveries of wind turbine components may be necessary. The proposed haul routes identified for the Project are detailed on Appendix A Figure 15. Following completion of construction, use of the improved and new access roads on private land will be limited to landowner and maintenance staff. Temporary road improvements such as shoulders on roads and expanded turning radii, and construction work areas (such as crane pads and erection areas) will be de -compacted and reseeded using an approved native seed mixture upon completion of construction. Both gravel and water will be required for road construction, concrete production, dust control, and other construction activities. These commodities may be provided from either existing, permitted off -site sources or newly developed and/or permitted on -site sources. If on -site water supplies or gravel pits will be developed, Leeward will comply with all local, state, and federal permitting requirements regarding development and use of such on -site sources. However, it is expected that the sources of water and gravel to be used for the Project will be similar to those used for the existing Cedar Creek I Wind Farm. Gravel and water required for construction will be obtained from existing permitted facilities . Section 5.9 (21-3- 330.C.2.g) provides a discussion of construction traffic routes and transportation considerations. Collection System A 34.5 -kV electrical collection system will gather the electricity from each wind turbine and route it to the interconnection substations. The majority of the collection system will be installed underground, typically along the rows of the wind turbines. Remaining portions will be installed aboveground, tying the rows of turbines together forming a "backbone" of the electrical collection system. Appendix A Figure 8 is an illustration of a typical installation structure that will comprise the overhead collection system for the Wind Energy Facility. The plot plan provided as Appendix A Figure 4 shows a representation of the collection system layout. At Project interconnection substations, voltage from the collection system will be increased from 34.5 -kV to 230 -kV or 115 -kV depending on transmission line capacity and interconnection site. From the Project interconnection substation, the above -ground Mountain Breeze Transmission Facility (230 -kV) or Panorama Transmission Facility (115 -kV) will connect the Project to the substations at Junction Switch Yard (or similar substation) and Redtail Substation (or similar substation) respectively. Interconnection Substations The Project substations will include breakers, switching and metering equipment, and a 34.5/230 -kV or 34.5/115 -kV step-up transformers, which will increase the voltage from the 34.5 -kV collection system to the Mountain Breeze Transmission Facility (230 -kV) or the Panorama Transmission Facility (115 -kV). Both project substations will interconnect at existing larger substations already connected to the regional Leeward Renewable Energy Development, LLC 5-11 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) electric grid. The Mountain Breeze Wind Energy Facility will interconnect to the Junction Substation (or similar facility) via the Mountain Breeze Transmission Facility. The Junction Substation will be upgraded or expanded to accommodate the needs of the Mountain Breeze Wind Energy Facility. The Panorama Wind Energy Facility will interconnect to the existing Redtail substation (or similar facility) via the Panorama Transmission Facility. All existing substation upgrades and/or expansions are anticipated to occur within the existing approximately 7 -acre Junction Substation (or similar facility) footprint or approximately 5 -acre Redtail substation (or similar substation) footprint. If upgrades and/or expansions cannot occur within existing footprints, then the substation owners (Tri-State for Redtail substation and Cedar Creek I for Junction) will amend their existing USRs. The substations will have graveled parking areas to accommodate maintenance vehicles. To prevent access to high -voltage equipment, the substations will be surrounded by chain -link security fencing. A locked vehicle gate will be located at the entrances to the main facility and the substations. Key boxes will be provided for emergency personnel. A detailed site plan for the substations will be provided prior to construction. Meteorological Towers The Project currently has 3 temporary 60 -meter meteorological towers. Leeward is requesting approval for up to three permanent meteorological towers at the Mountain Breeze Wind Energy Facility and up to three permanent meteorological towers at the Panorama Wind Energy Facility that will be up to 90 -meters in height and will remain in place to study and monitor wind resources for the Project during its operation. These permanent meteorological towers will be as tall as the hub height of the selected wind turbine(s) and will provide data critical to assessing the performance of the Project and aid in short-term forecasting for the Project. The permanent meteorological towers will comply with applicable FAA requirements. O&M Building The existing, currently permitted Cedar Creek I Wind Farm O&M building will be used for the Mountain Breeze and Panorama Wind Energy Facility. The O&M building includes offices, spare parts storage, kitchen, restrooms, and a maintenance shop area. Potable water is obtained from an on -site permitted well. Wastewater from the building will be discharged to an on -site currently permitted domestic septic tank and drain field. During operation of the Wind Energy Facility, Leeward will have between 15 to 20 part-time, full-time, or contractor employees (e.g., site manager, operations manager, and operating technicians) on site who will be responsible for operating and monitoring the facility, including coordination of all scheduled maintenance as well as forced outages and equipment malfunctions. Leeward staff includes Leeward Renewable Energy Development, LLC 5-12 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) approximately 30 part-time, full-time, or contractor employees that currently maintain Cedar Creek I. If required, Cedar Creek I will expand their existing facilities to accommodate the increase in operation employees. Cedar Creek I will seek the authorizations necessary for any expansions. The operating plan will include a schedule of outages to facilitate routine inspections and maintenance on the wind turbine generators. Inspection and maintenance activities will involve inspecting wear and tear on components such as seals, bearings, and bushings; lubricating the mechanical systems; and evaluating control systems. Temporary Facilities Other temporary facilities will be required for the construction phase of the Project, including two concrete batch plants, located in the vicinity of the Mountain Breeze and Panorama substations, laydown areas for an equipment and construction management facility, crane paths and working pads, and staging areas for turbine delivery. The laydown areas will include a construction trailer, sanitation facilities, and fencing for security and safety. Drinking water will be trucked in by the construction contractor in compliance with Chapter 14 of the Weld County Code. The temporarily affected areas will be restored to pre -construction conditions, to the extent practicable, after construction has been completed. Re - vegetation and seeding will be completed in accordance with specific landowner agreements and approved Weld County seed mixes. 5.6.4.2 Transmission Line Facilities The Wind Energy Facility will have up to two transmission lines, the Mountain Breeze Transmission Facility (230 -kV) and Panorama Transmission Facility (115 -kV). Mountain Breeze Transmission Facility will be approximately 11 -miles in length, and Panorama Transmission Facility approximately 15 -miles in length, both of which will be within a permanent 180 -foot right-of-way. The Mountain Breeze Transmission Facility will interconnect to Junction Switch Yard, or similar facility, within the southwest portion of Cedar Creek I Wind Farm (see Interconnection Substation discussion above in Section 5.6.41.). The Panorama Transmission Facility will interconnect to Redtail Substation, or similar facility, (see Interconnection Substation discussion above in Section 5.6.41.). Leeward requests a permit for the 180 - foot ROWs to construct the Mountain Breeze and Panorama Transmission Facilities. Leeward will design and construct the Transmission Facilities. Leeward's engineers, construction personnel and contractors will develop transmission systems that are reliable, safe, and effectively maintained. Leeward's Project development will minimize adverse environmental effects, while maintaining the Project's schedule. Leeward Renewable Energy Development, LLC 5-13 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) The structure specifications of the Transmission Facilities will be finalized prior to construction; however, they will likely consist of H -frame and guyed three -pole structures as engineering needs dictate, and they may be wood or steel. The two -pole H -frame structures will be approximately 100 feet in height. The two poles of the H -frame structure will be 20 feet apart. At angles of greater than 5 degrees, or at other locations where engineering needs dictate, guyed three -pole structures will be used. Guyed H -frame structures will be used at angles of less than 5 degrees. Structures will have a weathering finish. The pole spacing will be approximately 100 feet depending on terrain, existing obstructions, and the type of pole utilized. Final design specifications will be provided to Weld County prior to the start of construction (Table 5-2). Appendix A Figure 8 illustrates potential structure types for the Transmission Facilities. Table 5-2: Transmission Facility Structure Specifications Design Component H -Frame/ Guyed Three -Pole Voltage 230kV or 1 l5kV Right -of -Way Width 180 feet Average Span 800 feet Average Height of Structures 100 Average Number of Structures per Mile 7-8 Maximum Ground Clearance Beneath Conductor 30-40 feet Maximum Height of Machinery that can be Operated Safely Under Line 20 feet Circuit Configuration Single circuit, two or three- phase Two to four, temporary, 5 to 10 -acre laydown areas will be used to stage materials during construction. The laydown areas will be located near an existing road and on previously disturbed areas to the extent practicable. One laydown yard will be located at each of the wind facility substations and the remaining laydown yard(s) will be located near the transmission facility ROW. Final laydown yard locations will be identified on the final site plan provided to Weld County prior to construction. Temporary facilities related to the Transmission Facilities will be restored to pre -construction conditions upon completion of construction. No permanent employees will be necessary for the Transmission Facilities. Preventative maintenance for the Transmission Facilities will include routine ground patrols. The purpose of patrols is to detect equipment requiring maintenance, repair, or replacement. In addition to regular patrols, special patrols are conducted as needed, particularly after wind, ice, or severe lightning storms, when damage to conductors, insulators, and structures may occur.

Leeward Renewable Energy Development, LLC 1-3 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Project Overview 1.2 Purpose and Need The Project is proposed to help supply the region's demand for additional renewable energy resources. Electrical demand continues to increase in Colorado, largely as a result of continued growth and development along the Front Range. Public Service Company of Colorado's (PSCo) 2016 Colorado Electric Resource Plan is designed to acquire approximately 615 -MW of additional generation capacity resources that are expected to be needed through 2023 (PSCo, 2016). The recently constructed 600 -MW Rush Creek Wind Project provided 50 -MW of firm generation capacity, leaving approximately 565 -MW of remaining energy demand to fill. Although PSCo's demand for renewable energy dominates regional demand, other utilities such as Tri-state Generation and Transmission Association, Inc., the Platte River Power Authority, the Municipal Association of Nebraska, Colorado Springs Utilities, and the Colorado Electric Utility, located in Pueblo and owned by Black Hills Corporation, also contribute to the regional demand. This Project will help these regional utilities fulfill their energy needs. In 2004, Colorado voters passed Amendment 37, the Renewable Energy Requirement. This initiative requires that the state's largest utilities obtain a minimum of 3 percent of their electricity from renewable energy resources by 2007, 6 percent by 2011, and 10 percent by 2015. In March of 2007, House Bill 1281 was passed in Colorado. This bill increased the renewable energy requirement in Colorado from 10 percent to 20 percent for PSCo and extended the deadline for compliance from 2015 to 2020. Furthermore, Senate Bill 100 expanded the renewable portfolio standard to include a 10 percent requirement for cooperative and municipally owned utilities serving more than 40,000 customers. Finally, in November of 2007, Governor Bill Ritter issued the Colorado Climate Action Plan, which includes a goal to reduce greenhouse gas emissions in the utility sector by 20 percent by 2020. These state requirements, coupled with federal tax incentives, have created a high demand for renewable energy throughout Colorado. Predictably, utility -scale wind farms are making a significant contribution to Colorado's renewable energy goals and producing clean and renewable electricity. The Colorado Enterprise Zone (EZ) Program is designed to promote a business -friendly environment in economically distressed areas by offering state income tax credits that incentivize businesses to locate and develop in, and non-profit organization to assist with the needs of these communities. The program was created by the Colorado Legislature (Colorado Revised Statutes Title 39, Article 30). The Project is within the Colorado Weld County Colorado Enterprise Zone. The following benefits of the Project will help provide economic stimulus to the local community: Leeward Renewable Energy Development, LLC 1-4 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest - Application Requirements (21-3-330) Whenever possible, ground patrols and subsequent repair activities are scheduled to minimize damage to crops or property. Maintenance may include repairing frayed or damaged conductors, inspection and repair of poles, replacing damaged and broken insulators, and tightening hardware and connections. Transmission lines are sometimes damaged by storms, floods, vandalism, or accidents requiring immediate repair. Emergency maintenance involves prompt movement of crews to repair damage and replace equipment. If property damage results from repair activities, Leeward representatives will meet with landowners to arrange for property restoration or compensation. 5.6.4.3 Project Disturbance As discussed in Section 5.6.4.1, Leeward has not yet selected a turbine type; therefore, a layout is presented that will accommodate multiple turbine types. Each turbine model under consideration will use a subset of the 140 turbine locations identified. In addition, Leeward has identified primary and secondary access roads and collection line options for approximate acreage of temporary and permanent impacts (Table 5-3). For purposes of calculating impacts, up to 140 turbine locations and only primary access roads and collection lines were included.

Leeward is committed to beginning construction of both facilities as soon as possible but no later than 3 -years after County approval is granted in order to be compliant with Weld County Code unless an extension in time is granted be Weld County. Testing and commissioning of the Wind Energy Facility is included within the 12 -month construction period; however, the commissioning usually takes places at the end of construction activities. The Mountain Breeze Wind Energy and Transmission Facilities will be operational by the end of 2020.

Construction will normally take place during one 10 to 12 hour shift per day during daylight hours and five or six work days per week. During deliveries of large equipment and loads of supplies to the site, or if delays during construction are experienced and the schedule needs to be maintained, work periods may extend into multiple shifts, nighttime work hours, and up to seven days per week to allow for such deliveries when normal traffic on roadways is less active. Leeward Renewable Energy Development, LLC 5-18 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Although there will be many instances when the activities listed below will overlap and be conducted simultaneously rather than sequentially, the rough sequence of events for construction is summarized in the following list: 1. Construct the access roads and crane pads at each wind turbine generator location. 2. Prepare the site for the switch -yard substation. 3. Construct the wind turbine generator foundations. 4. Construct the substations. 5. Trench and install the energy collection system. 6. Assemble the wind turbine generators. 7. Commission the wind farm. 8. Complete any necessary restoration of the site. The Transmission Facilities will need to be completed, tested, and energized to provide a source of power for the automatic control system for the wind turbines. Accordingly, testing and commissioning of the turbines cannot begin until the construction of its associated Transmission Facilities and interconnections are complete, which is expected to last approximately 3 months and will be started in sufficient time so that testing of the turbines can begin on schedule. Table 5-5 provides an overview of the development schedule for the Transmission Facilities. Although there will be many instances when the activities listed below will overlap and be conducted simultaneously rather than sequentially, the rough sequence of events for construction of the Transmission Facilities is summarized in the following list: I. Prepare ROW. 2. Complete civil work for access roads and work area pad. 3. Drill structure and foundation holes. 4. Assemble and erect structure. 5. String conductor. 6. Site clean-up and restoration. The Transmission Facilities will employ approximately 10 to 20 people during construction activities. Construction will generally take place during a 10 to 12 hour shift per day during daylight hours and five to six workdays per week. The peak number of workers at any one time will be approximately 20 for each transmission facility. Leeward Renewable Energy Development, LLC 5-19 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Once the necessary land use permits have been obtained, Leeward will submit the remainder of their application to Weld County (i.e. access permits, building permit, and others). Leeward anticipates also submitting an application to the Colorado Department of Public Health and Environment (CDPHE) for an APCD APEN and Application for Construction Permit for land development, and a General Permit for Stormwater Discharges Associated with Construction Activity. Leeward may also submit, if necessary, an application to the U.S. Army Corps of Engineers (USACE) for a Nationwide Permit. A list of anticipated permits required for the Project is included in Appendix H. Leeward Renewable Energy Development, LLC 5-20 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.6.6 Hazards and Emergency Procedures (21-3-330.B.5.g) 5.6.6.1 Hazards to Humans Wind Energy Facility Hazards to humans from wind energy facilities are minimal and are primarily associated with the electrical infrastructure such as overhead electric lines. The greatest hazard is direct contact with the conductors or transformers, irrespective of voltage. Physical contact between a ground object and the high -voltage conductors is not necessary for electrical contact to be made, however; arcing can occur across an air gap. Extreme caution must be used when operating tall machinery and equipment. Given the rural nature of the proposed Project Area and Project setbacks incorporated into the site layout, the hazards of explosion, or other danger to the health, safety, and welfare of employees or the general public are minimal. Furthermore, none of the wind turbine generators or supporting facilities will be located in proximity to any existing residences or county roads, thereby further minimizing the incidence of danger to any individual. Wildfire is a concern that Leeward takes very seriously and has been actively involved in for many years through the Cedar Creek I facility. Leeward's Cedar Creek [ project enjoys the benefit of having a fire station and fire truck located in Grover, CO approximately 5 miles from the Mountain and Panorama Wind Energy Facility. Additionally, the Grover Fire Department recently built a remote facility at Cedar Creek I where they store two (2) fire trucks that are equipped and ready to be dispatched as needed. The water supply for the fire trucks is located in Grover, CO; however, Cedar Creek I recently built an upgraded water system onsite that the fire department could use if necessary. Cedar Creek I completed training with Northern Colorado Med Evac and the fire department last year and coordinated rescue efforts in the event of an emergency. The site has safety equipment on hand and has the turbine coordinates in the event they need to land a helicopter onsite. The same preparation will be completed at the Mountain and Panorama Wind Energy Facility. Finally, Cedar Creek I recently completed fire coding around the existing interconnection transmission line. The bulk of the collection system will be installed underground to minimize the potential for human contact. For the portions of the collection system or transmission lines installed overhead, the potential for human contact will also be minimized due to the height the line is suspended above the ground, and the rural location on private land away from public roads. Furthermore, whether above -ground or below - ground, all transmission lines and collection systems will conform to applicable standards for design clearances, and operations and maintenance. The switch yard substation will be fenced to prevent public Leeward Renewable Energy Development, LLC 5-21 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) access to this area. Safety signs will be posted around all high -voltage facilities and at underground cable crossings along roads in conformance with applicable state and federal regulations. Transmission Facilities Given the rural nature of the land comprising the area for the transmission lines, the hazards of explosion or other danger to the health, safety, and welfare of employees or the general public are minimal. The greatest danger from a transmission line is direct electrical contact with conductors. Since the transmission facilities will run through an uninhabited section of Weld County, far from any roads or homes on private land, and access to the Transmission Facilities is extremely limited, extreme caution must be exercised when operating vehicles and equipment for any purpose in close proximity to transmission lines. Wildfire and emergency response for the transmission facilities is similar to wind facilities as described above. Although the proposed transmission lines are designed with overhead ground wires and well-grounded poles to protect the system from lightning, the transmission line poles and conductors may occasionally be hit by lightning during a thunderstorm. Activities near transmission line poles and other tall objects, such as trees, should therefore be avoided during thunderstorms. All the Project's electric facilities will be designed, constructed, operated, and maintained to meet or exceed all applicable standards of design and performance commonly used in the industry. A perceived hazard associated with transmission lines, electric and magnetic fields (EMF), bears discussion. Considerable research and studies have been conducted to investigate potential health effects of EMF from high -voltage transmission lines on living organisms. Numerous scientific studies have been conducted to better understand whether there is a connection between EMF and certain adverse health effects. The National Institute of Environmental Health Sciences (NJEHS) concluded in a 1999 report that "virtually all of the laboratory evidence in animals and humans and most of the mechanistic work done in cells fail to support a causal relationship between exposure to ELF-EMF (Extremely Low Frequency Electric and Magnetic Fields) at environmental levels and changes in biological function or disease status," (N1EHS, 1999). Nonetheless, Leeward remains sensitive to the EMF issue and will promptly and accurately respond to inquiries with current available information. Appendix A Figure 9 shows expected levels of EMV for the proposed Mountain Breeze and Panorama Transmission Facilities. Leeward Renewable Energy Development, LLC 5-22 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Leeward has weighed potential health effects and the cost of mitigating those effects by using alignments that limit exposures (of electric and magnetic fields) to areas of concentrated population and group facilities such as schools and hospitals. The proposed Project maintains suitable distances from such areas. 5.6.6.2 Environmental Hazards Wind Energy Facility A Phase I Environmental Site Assessment (ESA) will be performed in general accordance with the consensus document known as American Society for Testing and Materials E1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process, 40 Code of Federal Regulation (CFR) Part 312 Standards and Practices for All Appropriate Inquiries (AAI) and ASTM Standard E2247-16 Phase I ESA Process for Forestland or Rural Property, which provides a guide for conducting environmental site assessments. The purpose of this ESA is to assist in developing information to identify releases or threatened releases of hazardous materials at the Project Site. There is no indication that there are any environmental hazards that will preclude construction of the proposed Wind Energy Facility. Enclosed containers will be provided for all trash. All construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials, will be removed to a disposal facility authorized to accept such materials. There will be no significant amounts of hazardous materials stored permanently at the Wind Energy Facility site. Small quantities of lubricants used in the facility will be stored within the O&M building or within similar temporary construction facilities. No explosives will be used for excavation purposes. Construction and O&M activities will comply with all applicable federal, state, and local laws and regulations regarding the use of hazardous substances. The only hazardous chemicals anticipated to be on site are those found in diesel fuel, gasoline, coolant (ethylene glycol), and lubricants in machinery. Hazardous materials will not be drained onto the ground or into streams or drainage areas. In the Project construction contract, Leeward will specify a preconstruction meeting with the contractor who will be required to ensure that all applicable laws and Leeward's procedures will be followed. Standard construction mitigation practices are attached as Appendix G. Leeward Renewable Energy Development, LLC 5-23 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Transmission Facilities Enclosed containment will be provided for all trash during construction of the Transmission Facilities. All construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials, will be removed to a disposal facility authorized to accept such materials. There will be no significant amounts of hazardous materials stored in the Transmission Facilities easements. Construction and O&M activities will comply with all applicable federal, state, and local laws and regulations regarding the use of hazardous substances. The only hazardous chemicals anticipated on site are those found in diesel fuel, gasoline, coolant (ethylene glycol), and lubricants in machinery. Hazardous materials will not be drained onto the ground or into streams or drainage areas. Leeward's construction contract with the Transmission Facilities contractor(s) will specify a preconstruction meeting that will require that all applicable laws and Leeward's procedures be followed. Standard construction mitigation practices are attached as Appendix G. 5.6.6.3 Emergency Procedures Wind Energy Facility The Wind Energy Facility will be managed and monitored by a staff of professional operators whose primary focus is to maximize the long-term value of the wind turbine assets. These operators are trained to respond to a variety of emergencies, including medical emergencies, fire, explosions, extreme weather or other events, that may endanger the health, safety, and welfare of employees or the general public. Leeward has already initiated consultation with the New Raymer-Stoneham and Pawnee Fire Protection Districts to discuss their concerns for a project within their response area. Leeward's projects develop emergency response plans in conjunction with nearby emergency response personnel and hospitals. Minimal fuel is involved at a wind energy facility, and therefore reduces the risk of fire. However, construction and O&M activities will require caution during high risk periods, especially in drought and red flag conditions. Medical emergencies can contribute a large portion of the risk associated with a wind farm. Typically, an area is developed within the wind energy facility site where it is safe for a medical helicopter to land. Leeward's Cedar Creek I Project has a location identified in their current safety plan. The Mountain Breeze and Panorama Wind Facilities will each have their own safety plans. If the Cedar Creek I helicopter location does not provide adequate coverage for the Mountain Breeze and Panorama Wind Facilities, then separate helicopter locations will be developed. Operators are trained to quickly notify the life -flight crew and to transport the injured to this area and await emergency response crews in the event of an emergency and identify the best location for the helicopter landing through site coordination and weather conditions. Leeward Renewable Energy Development, LLC 5-24 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) An emergency response plan will be developed for the construction and the operations phases of the Project. The plan will be written to include elements of the emergency response departments near the site, including how and when to communicate with the Weld County Sheriff's Office, the New Raymer- Stoneham and Pawnee volunteer fire departments, the Weld County Paramedic Services, and the Weld County Office of Emergency Management. The emergency response plan will include the following information: 1. Types of Emergencies a. Medical — Examples: Worker injury, heart attack b. Wildland fire — ignited onsite from construction or O&M activities, offsite from adjacent land uses, or naturally from lightning. c. Hazardous Material Release — Examples: Chemical storage spill, ruptured hydraulic hose d. Catastrophic — Examples: Earthquakes, tornado, or other high wind event e. Security — Threats to personnel or the Wind Energy Facility 2. What to do when an emergency occurs on your jobsite 3. Additional steps to follow for all emergencies listed above 4. Emergencies other than those requiring immediate hospitalization 5. Security threats The emergency response plan will contain forms for documenting incidents and provide instructions for how to maintain communications internally and externally during and after an emergency event. The access width requirements for emergency equipment (fire department) are a minimum of 20 feet. Leeward will continue to work with local fire departments to meet their requirements for emergency response. A new fire station was constructed in 2016 within the Cedar Creek I Wind Farm adjacent to the Project which will provide additional support in the event of an emergency. Leeward's Cedar Creek I Project has a fire station and fire truck located in Grover, CO approximately 5 miles from the Mountain and Panorama Wind Energy Facility. Additionally, the Grover Fire Department recently built a remote facility at Cedar Creek I where they store two (2) fire trucks that are equipped and ready to be dispatched as needed. The water supply for the fire trucks is located in Grover, CO; however, Cedar Creek I recently built an upgraded water system onsite that the fire department could use if necessary. Leeward Renewable Energy Development, LLC 5-25 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Transmission Facilities Regular patrols of the Transmission Facilities will occur. Appropriate field crews and engineering personnel are notified by telephone or radio if there is an issue and undertake the required procedures to correct the problem and restore the facilities to normal operations. Risks associated with construction of the Transmission Facilities are similar to those described above for the Wind Energy Facility. 5.6.6.4 Natural Hazards No known natural hazards exist in the area that will affect or be affected by the Wind Energy Facility or the Transmission Facilities. The Project does not occur within any mapped FEMA floodplains and does not anticipate facilities will be built in known floodplains. 5.6.7 Name, Address, and Telephone Number of the Applicants and Fee Owners (21-3-330.B.5.h — i) • Applicant: Leeward Renewable Energy Development, LLC 6688 North Central Expressway, Suite 500 Dallas, Texas 75206 John Wycherley Senior Director of Development (214)515-1100 • Subsidiaries for the Mountain Breeze and Panorama Wind Energy Faculty include: o Mountain Breeze Wind, LLC 6688 North Central Expressway, Suite 500 Dallas, Texas 75206 o Panorama Wind, LLC 6688 North Central Expressway, Suite 500 Dallas, Texas 75206 See Appendix D for information regarding fee owners. 5.6.8 Legal Description of the Property Under Consideration (21-3-330.B.5 j) The legal descriptions of all properties within the boundaries of the proposed Project are included in Appendices D and E.

Total acreage of the Panorama Transmission Facility ROW is up to approximately 330 acres of transmission line ROW. 5.6.10 Existing Land Use (21-3-330.B.5.l) Wind Energy Facility The existing land use within the Wind Energy Facilities is agricultural, including a mix of dryland farming and grazing, see Appendix A Figure 5. Residential buildings and outbuildings are scattered in low density throughout the Wind Energy Facility ,. There are adjacent lands to the lease lands included in the Wind Energy Facilities that area owned by U.S. Forest Service, Pawnee National Grasslands and U.S. Department of Defense (DOD; missile silos); these lands are not part of the Mountain Breeze and Panorama Wind Energy Facility. Land enrolled in the CRP program will maintain CRP status, with the exception of the permanent disturbance within the turbine tower and new access road footprints, which will either comply with allowed exclusions to the CRP program or will be withdrawn from the program with compensation paid to landowners by Leeward for lost CRP payments. Producing and abandoned oil and gas wells are shown on Appendix A Figure 6. No impacts to oil and gas wells will occur based on the indicative layout of the Wind Energy and Transmission Facilities. Current technology also allows access directionally further reducing the likelihood of impacts to these operations. In designing and micrositing the Wind Energy Facility, Leeward will comply with setbacks regarding placement of the wind turbines to provide adequate buffers to adjacent land uses. Table 5-6 provides a list of setbacks which Leeward will be committed to for the Wind Energy Facility.

TH = tip height BL = blade length (or rotor radius) Leeward Renewable Energy Development, LLC 5-28 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Transmission Facilities The indicative Transmission Facility routes are located along existing section lines where possible to minimize the impact on the landowner's land. The land is currently used for agricultural uses, as either farm or range land along the entire length of the routes (Appendix A Figure 4). Illustrations of transmission structures are provided in Appendix A Figure 8. 5.6.11 Existing Land Uses of All Properties Adjacent to Parcel (21-3-330.B.5.m) All properties adjacent to the Wind Energy Facility are agricultural (grazing or dryland farming) land, CRP land, or are under the ownership of the State of Colorado or the federal government. Several parcels of land adjacent to the Project are located within the Pawnee National Grasslands. Land uses of properties adjacent to the Transmission Facilities ROWs are displayed in Appendix A Figure 5. In general, adjacent land use consists of agricultural farming, grazing activities, DOD facilities, and dispersed recreation. 5.6.12 Present Zone and Overlay Zones (21-3-330.B.5.n) As mentioned above, the entire area is zoned Agricultural, and there are no overlay zones within the proposed Wind Energy Facility or Transmission Facilities. No floodplains are mapped in the Project Area (FEMA, 2018). There are no Federal Aviation Administration (FAA) CFR Part 77 restrictions within the vicinity of the Wind Energy Facility. Although the Project is within a DOD area, the Project will not affect navigable airspace. Leeward verified the proposed Project will have no impact to any private, commercial, or military airport by obtaining a "Determination of No Hazard" approval from the FAA in May 2018 for a large sampling of the Project Area. Further determination will be sought from the FAA once layouts have been finalized, The western portion of the Project Area occurs within a known military training air space; however the operational height of the Wind Energy Facility is not expected to interfere with military operations. 5.6.13 Signatures of the Applicant and Fee Owners or their Authorized Legal Agent (21-3-330.B.5.o) A list of easement agreements obtained to date is included as Appendix E. Copies of the easement agreements have been provided in Appendix E. A map of the leased parcels is provided in Appendix A Figure 4. A legal description of the lands under easement agreement, along with the names and contact information for the land owners, is included in Appendix D. Leeward Renewable Energy Development, LLC 5-29 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.7 Natural and Socioeconomic Environmental Constraints Affecting Site Selection and Construction (21-3-330.B.6) Wind Energy Facility Areas of sensitive natural environments, including riparian areas, water bodies, and areas of potentially suitable habitat for threatened and endangered species, are limited in the Wind Energy Facility Project Area. Two spring 2018 surveys were conducted at the proposed Project and neighboring Cedar Creek I Wind Farm to assess the presence of plains sharp -tailed grouse (Tympanuchus phasianellus), a Colorado state -listed endangered species, within the site. Over the course of the surveys, 4 sharp -tailed grouse leks were identified within the Project Area and 9 observation points were identified where sharp -tailed grouse were seen within the Project Area. A summary of the study for cultural resources is in Appendix I. When siting wind energy facilities, avian and bat migratory corridors and concentration areas are generally avoided because collisions with turbine blades present a risk to avian species and bats. The Wind Energy Facility is within the Central Flyway for migratory birds which includes Colorado, Nebraska, and Wyoming. Studies to evaluate the potential for avian and bat collisions at the Wind Energy Facility were designed according to USFWS Wind Energy Guidelines (2012) and have been ongoing since February 25, 2017. Two full years of avian use surveys were completed in May 2018. Two aerial avian surveys were conducted in February and May 2017 and again in March and May 2018. Survey results from 2017 and 2018 identified 39 and 21 active nests respectively and 135 and 54 inactive nests respectively. Facility infrastructure, including turbine strings and transmission line corridors, were set back from the nests in accordance with recommendations offered by CPW for permanent and season construction set -backs. Leeward has developed the Project according to WEG. Leeward will continue to follow WEG through the final development and operation of the Project as well as any additional guidance provide by USFWS and CPW through Leeward's continued coordination with these agencies. Consultation with CPW and USFWS has been ongoing since the early 2,000s and most recently from 2017 to the present to share study protocols, results, Project status, and to facilitate the incorporation of appropriate mitigation measures into the Wind Energy Facility design. The general construction mitigation measures Leeward has committed to are included in Appendix G. Additional mitigation measures Leeward will complete specifically for ecological resources include: 1. Preconstruction surveys have been completed according WEG. Additional surveys will be completed according WEG for the construction and post -construction phases of the Project. Based on the likely timing of construction preconstruction surveys for avian species will occur in order to comply with MBTA and BGEPA. Leeward Renewable Energy Development, LLC 5-30 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 2. Construction timing constraints to avoid breeding seasons for certain species in some areas or for certain activities. 3. Additional study of potential impacts and species reaction to presence of the Wind Energy Facility. Prior to applying for building permit applications, final locations for facility components and final mitigation measures will be determined. Water bodies and wetland resources within the vicinity of the Project include intermittent and ephemeral streams and drainages, artificial paths, and small unnamed ponds. These occur in areas of low topography where surface run-off typically collects. These locations are not compatible with the desired locations for wind turbines, which are typically placed in areas of higher topography to capture the higher wind speed and density. Preliminary desktop assessment and mapping of the lakes, wetland resources, and features that could be considered for designation as "waters of the U.S." was conducted. According to mapped NWI and NHD datasets there are no waters of the U.S. located in areas with proposed facilities. All facilities associated with the Project have been sited to avoid or minimize impacts to these important resources. Field verification will be completed prior to construction for all areas with proposed facilities and where wetland and water body resources may occur to minimize impacts to water resources. If needed, Leeward will obtain the appropriate Nationwide Permit from the U.S. Army Corps of Engineers. There are no known socioeconomic constraints associated with the proposed Project. Transmission Facilities Based on criteria listed in Section 3 above, the Preferred Alternative for each of the Transmission Facilities was selected as shown on Appendix A Figure 2. The proposed routes minimally impacted area buildings and residences as well as the existing Cedar Creek I Wind Farm turbine arrays. Transmission facilities have been developed to minimize impacts to sensitive natural and human resources. Data for cultural, water, wildlife, ecology, and other resources was applied when the Transmission Facility locations were sited. Areas of sensitive habitats, water bodies, and wetlands have been avoided where possible. A number of golden eagle nests have been identified within the 10 -mile aerial survey area completed by Leeward in the spring and early summer of 2017 and 2018. To minimize disturbance to sensitive species, Leeward is working closely with USFWS and CPW to develop the Project facilities, protect important habitat and minimize impacts to species. Leeward Renewable Energy Development, LLC 5-31 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) There are no known socioeconomic constraints associated with the Project. The final Transmission Facility routes will follow the proposed indicative route as closely as possible but may be shifted based on the ability to acquire right-of-way easements from landowners. The final Transmission Facility routes and engineering details will be provided to Weld County prior to construction. The final Transmission Facility routes will avoid and minimize impacts to environmental and community resources. 5.8 Natural and Socioeconomic Environmental Impacts from Construction of the Wind Energy Facility (21-3-330.B.7) This section describes the impacts of the proposed Project on various environmental resources in Weld County and addresses the applicable requirements of 21-3-330 of the Weld County 1041 Regulations. For purposes of analyzing environmental impacts in this application, the Project Area is defined as the area within the Wind Energy Facility and Transmission Facilities that will be disturbed by construction, as shown on Appendix A Figure 2. 5.8.1 Land Use Existing land uses will continue uninterrupted for the majority of the land within the site boundary for the Wind Energy Facility and Transmission Facilities. Permanent impacts anticipated will include less than 1 percent of the Project area. Temporary impacts will include less than 5 percent of the Project area. Impacts will include footprints of turbines, access roads, substations, structures for the Transmission Facilities, and the collection system structures. Agricultural productivity will be minimally impacted as farming and grazing activities may continue up to the base of the wind turbines. Land use along the proposed Transmission Facilities will be minimally impacted and will continue to include a mix of agricultural and residential uses. Minimal effects to agricultural productivity will occur as a result of the Project. Further discussion of the impacts of the proposed Project on land use, including conformance with Land Use Plans, agricultural lands, use of existing ROW can be found below in Section 5.9.1. 5.8.2 Vested Water Rights No additional water rights are anticipated for the Project for this decision. The existing and permitted Cedar Creek I O&M building is the only anticipated facility requiring an on -site water well for long-term water supply. The volume of water use for the O&M building will be similar to the volume of a residence with water used for drinking, showering, toilets, etc. Leeward plans to use the existing Cedar Creek i O&M facility for O&M of the proposed Mountain Breeze and Panorama Wind Energy Facility. Any necessary expansion of the existing Cedar Creek I facility will be addressed by Cedar Creek 1. Leeward Renewable Energy Development, LLC 5-32 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) During construction, water for the concrete batch plants, dust control, and drinking water will be obtained by the construction contractor from existing permitted sources. In addition, port -a -johns will be used at select locations in the Project during construction which will be used by wind farm employees, construction workers, and contractors. Leeward will comply with all local, state, and federal permitting requirements and water rights processes regarding development and use of such sources, if necessary. All necessary permits and approvals have or will be obtained by Leeward prior to construction. 5.9 Environmental Impact Analysis (21-3-330.C.2) The Project Area was analyzed based on environmental resource data, wildlife, avian, wetland, and archaeological, that was collected during desktop analysis and site surveys to determine if any areas should be avoided due to potential impacts to valuable wildlife, avian, wetland, or archaeological resources. Geographic data was obtained from the following sources: • U.S. Department of Agriculture, Natural Resource Conservation Service • U.S. Department of the Interior, Geological Survey • U.S. Department of the Interior, USFWS • U.S. Department of Homeland Security, FEMA • Colorado Historical Society, Office of Archaeology and Historic Preservation • Colorado Parks and Wildlife • Colorado Department of Transportation • Weld County Planning Department 5.9.1 Land Use Ninety nine percent of the land cover within the Project Area is classified as grassland/herbaceous, cultivated crops, open space developed and pasture/hay (USGS, 2014). The primary land use within the area is agriculture based, including range land, pastures, hay fields and cultivated crop land. Appendix A Figure 5 provides an overview of land cover and land use within the Project Area. The proposed use will be compatible with the surrounding land uses. The land uses surrounding the site are agricultural lands used for dryland farming and grazing, CRP lands, scattered residential properties, radio towers, dispersed recreation, and missile silos managed by the U.S. Department of Defense (DOD). The current Project design has incorporated setback standards from the silos, parcel boundaries, and residential homes to avoid impacts to residents and DOD's operations. Leeward Renewable Energy Development, LLC 5-33 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Existing land uses will continue uninterrupted for the majority of the land within the site boundary for the Wind Energy and Transmission Facilities. Table 5-3 and Table 5-4 provide anticipated permanent and temporary impacts which include footprints of turbines, access roads, substations, structures for the Transmission Facilities, and the collection system structures. Agricultural productivity will be minimally impacted as farming and grazing activities may continue up to the base of the wind turbines. Land use along the proposed Transmission Facilities will be minimally impacted and will continue to include a mix of agricultural and residential uses. During construction, water for the concrete batch plant, dust control, and drinking water will be obtained by the construction contractor from existing, permitted sources. Leeward will comply with all local, state, and federal permitting requirements and water rights processes regarding development and use of existing, permitted water sources. 5.9.1.1 Conformance with Land Use Plans The Weld County Code, Chapter 22, Comprehensive Plan, has been reviewed and the proposed wind farm is consistent with the intent of the Comprehensive Plan, including Land Use, Environmental Resources, and Natural Resources. The proposed wind farm supports Weld County's Alternative Energy Resources Goals and Policies (Sec. 22-5-140) and is consistent with the Economic Development Goals and Policies (Sec. 22-6-20). The current use of the site and the surrounding area is dryland farming, grazing and CRP land. The proposed use will not compromise the goals of agricultural land use or any other land use category. The Project will not impact effective and efficient delivery or place undue strain on adequate public facilities and services or other land use amenities. Areas of sensitive natural environments, including riparian areas, water bodies, and areas of potentially suitable habitat for threatened and endangered species are not prevalent on the proposed site for the wind energy facility. Impacts to environmental resources such as air, water, waste, noise, and public health will be minimal. Mitigation practices will minimize impacts from dust generation and waste products. An erosion control/stormwater management plan will be developed and implemented to prevent or minimize sediment entry to the drainages within the overall Project Area. During construction, vegetation may be removed and much of it will be reclaimed once the construction period is complete, a small amount of the Project will be subject to permanent impacts as shown in Table 5-3 and Table 5-4. Similarly, wildlife may be temporarily displaced during construction but will be able to return to the site once the construction period ceases. Leeward Renewable Energy Development, LLC 5-34 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) All areas of potential soil disturbance within the Project Area will be surveyed for noxious weeds before construction begins. Noxious weeds will be managed in all surface disturbed areas. If herbicides are needed to control noxious weeds, they will be applied by a licensed contractor. Equipment will be washed at a commercial facility prior to construction and on -site during construction if weeds are found within or adjacent to the Project Area. A Leeward contractor will be responsible for monitoring, treating, and documenting noxious weeds throughout the life of the Project. A weed management plan will be developed that discusses both general and species -specific weed control methods. 5.9.1.2 Agricultural Land The agricultural sector is an important element of the County economy and Weld County is one of the economically largest agricultural producing counties in the nation. A benefit of wind farm development is that future agricultural production will not be precluded by the proposed use. The Natural Resource Conservation Service (NRCS) classifies prime farmland as land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops and is also available for these uses. It has the soil quality, growing season, and moisture supply needed to produce economically sustained high yields of crops including soils that are not excessively erodible (NRCS, 2017). Thirty-eight percent of the Project Area is designated as farmland of statewide importance, 19 percent is considered prime farmland if irrigated, and 43 percent is not prime farmland (NRCS, 2017), as shown on Appendix A Figure 10. Only land surrounding the base of the structures will be removed from agricultural operations. Agricultural productivity will be minimally impacted as farming and grazing activities may continue up to the bases of the wind turbines. Land between structures will remain available to farming and ranching or other operations that do not interfere with safe and reliable operation of the wind facility and transmission lines. 5.9.1.3 Use of Existing Rights -of -Way The Project will interconnect to existing transmission lines and substations. Where possible, existing electrical generation infrastructure will be used. Specific access through existing gates or through new locations will be agreed upon by Leeward and each property owner. Layout of the wind energy facility will minimize the need for new, permanent roads using existing access roads and county roads wherever possible. The adjacent Cedar Creek I Wind Farm has established improved roads and maintenance facilities. Within the acquired ROW for the transmission line corridor, access will occur primarily along existing roads or via overland access. New roads will be built only when necessary for construction or maintenance purposes. Existing county roads and state highways will be used to access the ROW whenever feasible. Leeward will acquire access easements from adjacent landowners if required. Leeward Renewable Energy Development, LLC 5-35 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.9.2 Other Utility Facilities (21-3-330.C.2.b) Appendix A Figure 11 shows existing major facilities of a public utility within the County of the type proposed for development. Leeward's consultant, Capital Airspace Group, completed an analysis of microwave paths for the Mountain Breeze Wind Energy Facility and the Panorama Wind Energy Facility (see Appendix O). The Mountain Breeze Wind Energy Facility contains one unique microwave link that overlies the Project Area. However, none of the proposed Mountain Breeze Wind Energy Facility turbines (including their rotor swept area) should obstruct licensed or applied non-federal microwave link Fresnel zones. The Panorama Wind Energy Facility contains one unique microwave link that overlies the Project Area. However, none of the proposed Panorama Wind Energy Facility turbines (including their rotor swept area) should obstruct licensed or applied non-federal microwave link Fresnel zones. 5.9.3 Water Resources (21-3-330.C.2.c) The following section describes the potential adverse effects of the proposal upon plant and animal life dependent upon the water resources in question. 5.9.3.1 Floodplains No floodplains are mapped in the Project Area (FEMA, 2018). 5.9.3.2 Surface Water The South Platte River is considered the nearest traditional navigable water to the Project Area and is over 30 miles away. Surface water within the Project Area includes intermittent and ephemeral streams and drainages, artificial paths (ditches), and small unnamed ponds (Appendix A Figure 12). Surface waters within the Project Area occur in areas of low topography where surface run-off typically collects. The surface water locations are not compatible with the desired locations for wind turbines, which are typically placed in areas of higher topography to capture the higher wind speed and density. However, other facility components such as access roads and electrical lines may cross water features. A desktop assessment was conducted to map surface water that could be considered for designation as "waters of the U.S." as well as other water resources. No known waters for the U.S. are mapped in areas that would be impacted by proposed Project facilities. All facilities associated with the Project have been sited to avoid or minimize impacts to surface water resources to the extent practicable. Leeward will develop and implement a Storm Water Management Plan (SWMP) to control erosion and sedimentation as to minimize impacts to surface waters. There are no natural surface water constraints significant enough to preclude selection of the proposed site or to preclude construction of the proposed Wind Energy Facility and transmission lines while avoiding significant impacts to surface water resources. A complete assessment and mapping of surface water resources will be performed prior to final Project design and Leeward Renewable Energy Development, LLC 5-36 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) layout so that road or other Project feature locations may be moved to ensure the avoidance of and minimal impacts to water resources. 5.9.3.3 Aquatic Species There are no perennial streams or large waterbodies located within the Project Area. The surface waters within the Project Area are ephemeral and intermittent. In an especially wet year, these drainages may fill with water and support small fish and aquatic invertebrates that play an important role in the food chain to support larger species of mammals and birds. However, the water features within the Project Area generally do not support aquatic species therefore impacts are not anticipated. 5.9.4 Significant Environmentally Sensitive Factors (21-3-330.C.2.d) The following section analyzes significant environmentally sensitive factors. These factors are identified on Appendix A Figure 13. 5.9.4.1 Wetlands and Marshlands Wetlands and playa lakes provide important habitat to waterfowl and other wildlife. Wetlands occur in areas that are saturated with water for part or all the year, have hydric (i.e. anaerobic) soils, and support a variety of hydrophytic plants. USFWS National Wetlands Inventory (NWI) maps were used to identify probable locations of wetlands as shown on Appendix A Figure 12 (USFWS, 2018a). NWI maps show the location and shape of potential wetlands and classify them into categories based on vegetation, water regime, salinity, and other wetland characteristics. NWI maps have the capability to accurately show the location and extent of conspicuous wetland types such as ponds and emergent wetlands but are not as accurate in showing inconspicuous wetlands such as scrub -shrub or forested wetlands. The NWI data was reviewed to identify potential wetlands within the Project Area. The data indicates 124 wetlands mapped in the Project Area including freshwater emergent wetlands, freshwater ponds and riverine. Project facilities have been developed to avoid impacts to wetlands and comply with ACOE regulatory requirements. A complete assessment and mapping of these wetland and water body resources will be performed in accordance with the 1987 USACE Wetlands Delineation Manual and Regional Supplement (USACE, 1987; 2010) to support final Project design and layout. Features identified in preconstruction field work will be used to support final micrositing to avoid and minimize impacts to water resources. No permanent impacts are anticipated to wetlands or water resources. If permanent impacts are anticipated to occur, activities will be authorized under the appropriate Nationwide Permit prior to construction. Leeward Renewable Energy Development, LLC 5-37 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) The Project will incorporate avoidance or minimization measures into the Project design to reduce impacts to wetlands and waterbodies. Any authorized temporary impacts to jurisdictional wetlands will be mitigated through implementation of BMPs. Silt fencing may be used to prevent sedimentation into lands adjoining the outer limit of the Project. If used, silt fencing will be keyed into site soils at the outer limits of the Project footprint along the entire Project corridor. The fencing will be regularly maintained by the construction contractor for the duration of the construction and restoration phase. Construction will be monitored to avoid temporary wetland impacts where possible, and to minimize them if avoidance is not possible. Steps to avoid and minimize impacts during construction include topsoil segregation, immediate post -construction slope stabilization, ditch blocks, silt fencing, and equipment support matting. Immediate restoration of soils to preconstruction compaction and grades (original) along with the planting of sterile, annual grasses followed by native perennials will confirm the best restoration of these sensitive areas. If temporary wetland impacts occur, restoration will occur following construction. Restoration activities will require any temporarily disturbed wetland areas be returned to preconstruction contour and the areas revegetated with hydrophytes native to the Project Area. Seed mixes will be approved by Weld County or other authorized agencies, as appropriate. 5.9.4.2 Vegetation The Project is located within the High Plains Level III ecoregion. This ecoregion is higher in elevation and drier than the Central Great Plains to the east, and in contrast to the irregular, mostly grassland or grazing land of the Northwestern Great Plains to the north. Much of the High Plains is comprised of smooth to slightly irregular plains having a high percentage of cropland (Chapman, et. al., 2006). Grama- buffalo grass is the potential natural vegetation in this region, with Trans -Pecos shrub savanna to the south, and taller grasses to the east. The northern boundary of this ecological region is the northern limit of winter wheat and sorghum and the southern limit of spring wheat crops. Within the High Plains Level III ecoregion, the Project Area is also located within the Moderate Relief Plains and Flat to Rolling Plains Level IV sub-ecoregions. Moderate Relief Plains are irregular plains with slopes greater than the rolling plains. Land use is predominately rangeland and soils are silty and clayey loams, formed from eolian sediments. Flat to Rolling Plains are more level and less dissected than Moderate Relief Plains. Soils are generally silty with a veneer of loess. Dryland farming is extensive, with areas of irrigated cropland scattered throughout, and winter wheat is the main cash crop. Based on U.S. Geological Survey (USGS) LANDF IRE Map Units and LANDFIRE/GAP Land Cover Map Unit Descriptions (LANDFIRE, 2008), the predominant vegetation systems within the Project Area include Western Great Plains Shortgrass Prairie, Western Cool Temperate Developed and Undeveloped Ruderal Grasslands, Western Cool Temperate Wheat, Introduced Upland Vegetation -Perennial Grassland Leeward Renewable Energy Development, LLC 5-38 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) and Forbland, Inter -Mountain Basins Semi -Desert Shrub -Steppe, Western Great Plains Sandhill Grassland, Western Cool Temperate Fallow/Idle Cropland and Western Cool Temperate Close Grown Crop. Below are summaries of the six LANDFIRE/GAP Land Cover Map Unit Descriptions that make up the majority (over 97 percent) of the Project Area. Western Great Plains Shortgrass Prairie is found primarily in the western half of the Western Great Plains. This system occurs primarily on flat to rolling uplands with loamy, ustic soils ranging from sandy to clayey. In much of its range, this system forms the matrix system with blue gramma (Bouteloua gracilis) dominating this system. Associated graminoids may include species such as purple threeawn (Aristida purpurea), sideoats gramma (Bouteloua curtipendula), buffalo grass (Buchloe dactvloides), needle and thread (Hesperostipa comate), prairie June grass (Koeleria macrantha), western wheatgrass (Pascopyrum smithii), and Sporobolus cryptandrus (Sand dropseed). Although mid -height grass species may be present, especially on more mesic land positions and soils, they are secondary in importance to the sod -forming short grasses. Scattered shrub and dwarf -dwarf species such as sand sagebrush (Artemisia filifolia), fringed sage (Artemisiafrigida), four -wing saltbrush (Atriplex canescens), broom snakeweed (Gutierrezia sarothrae), and pale desert -thorn (Lycium pallidum) may also be present. A large part of the range for this system (especially in the east and near rivers) has been converted to agriculture. Areas of the central and western range have been impacted by the unsuccessful attempts to develop dryland cultivation during the Dust Bowl of the 1930s. The short grasses that dominate this system are extremely drought- and grazing -tolerant. These species evolved with drought and large herbivores and, because of their stature, are relatively resistant to overgrazing. This system in combination with the associated wetland systems represents one of the richest areas for mammals and birds. Introduced Upland Vegetation -Perennial Grassland and Forbland are areas dominated by introduced perennial forb or grassland species such as: Canada thistle (Circium arvense), bull thistle (Circium vulgare), knapweeds (Centaurea spp.), leafy spurge (Euphorbia esula), peppergrasses (Lepidium sp)., white sweet clover (Melilotus albus), crested wheatgrass (Agropyron cristatum), smooth brome (Bromus inermis), Kentucky bluegrass (Poa pratensis). Inter -Mountain Basins Semi -Desert Shrub -Steppe occurs throughout the intermountain western U.S., typically at lower elevations on alluvial fans and flats with moderate to deep soils. This semi -arid shrub - steppe is typically dominated by graminoids (>25% cover) with an open shrub to moderately dense woody layer with a typically strong graminoid layer. The most widespread (but not dominant) species is Bluebunch wheatgrass (Pseudoroegneria spicata). Characteristic grasses include Indian rice -grass (Achnatherum hymenoides), blue gramma, salt grass (Distichlis spicata), sandberg bluegrass (Poa Leeward Renewable Energy Development, LLC 5-39 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) secunda), needle and thread, and wild rye (Leymus salinus). The woody layer is often a mixture of shrubs and dwarf- shrubs, although it may be dominated by a single species. Characteristic species include four - wing saltbrush, big sagebrush (Artemisia tridentate), rabbitbrush (Chrysothamnus spp.), and winterfat (Krascheninnikovia lanata). Annual grasses, especially the exotics Japanese Brome (Bromusjaponicus) and cheat grass (Bromus tectorum), may be present to abundant. Forbs are generally of low importance and are highly variable across the range but may be diverse in some occurrences. The general aspect of occurrences may be either open shrubland with patchy grasses or patchy open herbaceous layers. Western Cool Temperate Developed Ruderal Grassland are areas dominated by herbaceous vegetation resulting from succession following significant anthropogenic disturbance of an area. It is generally characterized by unnatural combinations of species (primarily native species, though they often contain slight or substantial numbers and amounts of species alien to the region as well). Western Cool Temperate Undeveloped Ruderal Grassland are areas dominated by ruderal successional vegetation found in open spaces of the western cool temperate region. Forest vegetation resulting from succession following significant anthropogenic disturbance of an area. It is generally characterized by unnatural combinations of species (primarily native species, though they often contain slight or substantial numbers and amounts of species alien to the region as well). Western Cool Temperate Wheat are areas used to produce wheat. Crop vegetation accounts for greater than 20 percent of total vegetation. Several parcels of land adjacent to the Project Area are part of the Pawnee National Grassland which is made up of 193,060 acres and administered by the Arapaho -Roosevelt National Forest Rocky Mountain Region. The most common habitat on the Pawnee National Grassland is open steppe (Hazlett, 1998). The dominant species are blue gramma and, to a lesser extent, buffalo grass. Other characteristic plant species of open steppe habitat are three awn, fringed sage, rabbitbrush, snakeweed, ring muhly (Muhlenbergia torreyi), prickly pear cactus (Opuntia polyacantha), western wheatgrass, and scarlet globemallow (Sphaeralcea coccinea) (Hazlett, 1998). The majority of disturbance to vegetation from construction activities will be temporary impacts to grasslands and agricultural (grazed or dryland farmed) lands. Temporarily disturbed areas associated with construction of collection lines, temporary access roads, and work areas along the overhead transmission line routes, will be reclaimed to preconstruction contours and seeded with a native seed mix. These areas will be restored to their original condition by de -compaction where needed, re -grading, and replanting the Leeward Renewable Energy Development, LLC 5-40 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) area with a weed -free mix of species suitable to the area and approved by the NRCS. NRCS will be consulted regarding appropriate reclamation methods. Long-term disturbance to vegetation will occur within the footprint necessary for the Wind Energy Facility and transmission line infrastructure (turbines, transmission structures, etc.). Project infrastructure will be sited to avoid all sensitive vegetation areas including riparian and wetland habitats. Noxious Weeds Weld County has an obligation to control noxious weeds on lands within the County as established by the Pest Control Districts Act (Section 35-5-101 et seq., CRS) and the Colorado Weed Management Act (Section 35-5.5-101 et seq., CRS). Pursuant to Chapter 15 (Weld County Code Ordinance 2005-10), Article 1 and II of the Weld County Code, noxious weeds are a public nuisance and are subject to remedies in accordance with the code and state statutes. The Colorado Department of Agriculture works closely with the state's counties to manage noxious weeds through the Rules Pertaining to the Administration and Enforcement of the Colorado Noxious Weed Act (Noxious Weed Rule, 8 CCR 1206-2) (Colorado Department of Agriculture, 2018). Management plans have been established for List A, B, and C Species in Colorado. Eradication is the management plan across the state for List A noxious weeds. Eradication means the reduction of reproductive success of a noxious weed species or specified noxious weed populations in largely un- infested regions to zero and permanently eliminating the species or populations within a specified period of time until the seed bank is eliminated. List 13 noxious weed species are those for which state, local governments, and other interested parties develop noxious weed management plans designed to stop the continued spread of these species. List C Species have management plans designed to support the efforts of governing bodies to facilitate more effective integrated weed management on private and public lands, but the goal of the plans is to provide additional education, research, and biological control resources to jurisdictions which choose to require management of List C Species. Watch List Species do not have management plans designed to control their spread but have been determined a potential threat to agricultural productivity and environmental values of the state. The Watch List is intended to service as advisory and educational purposes only. Colorado List A, B, and C Species effective March 31, 2017 are provided in Table 5-7 (Colorado Department of Agriculture, 2018). There is a total of 25 List A Species, 40 List B Species, and 16 List C Species identified in the table with potential to occur in the Project Area. Watch List species are not included because there are no management plans prescribed to control Watch List species in Colorado. Leeward Renewable Energy Development, LLC 5-41 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Species which have been reported in Weld County are indicated with an *, and List B Species are set for minimum control/suppression around the State and possibly eradication depending on the size of the infestation in a specific County (Weld County, 2018a).

Pursuant to Chapter 15, Article I and II of the Weld County Code, if noxious weeds exist on the property or become established because of the proposed Project, Leeward will be responsible for controlling the noxious weeds. Equipment will be washed at a commercial facility prior to construction and on -site during construction if weeds are found within or adjacent to the Project Area. Leeward will also avoid the use of noxious weeds in any temporarily restored areas or landscaping during Project development. A Leeward designated licensed contractor will be responsible for monitoring, treating, and documenting noxious weeds throughout the life of the Project. 5.9.4.3 Wildlife and Wildlife Habitat (21-3-340.A.14) Information on wildlife and habitat was obtained from a review of existing data, including the USFWS Information, Planning, and Conservation (IPaC) database (USFWS, 2018b), CPW, and Colorado Natural Heritage Program (CNHP) species occurrence data (CNHP, 2018). Consultation with USFWS, USFS, and CPW most recently began in May 2017 which consisted of a letter notifying the agencies of the Project and requesting their input regarding the Project, in -person meetings, several conference calls and email correspondence. The agencies were also invited to attend the open house on October 2, 2018 (Appendix B). Coordination with these agencies will continue throughout the planning phase to develop Leeward Renewable Energy Development, LLC 5-44 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) the appropriate mitigation for Project impacts. The results of existing information reviewed and studies are provided below. Mammals likely to occur in the Project Area include mule deer (Odocoileus hemionus), white-tailed deer (Odocoileus virginianus), pronghorn (Antilocapra americana), coyotes (Canis latrans), red fox (Vulpes vulpes), swift fox (Vulpes velox), eastern spotted skunk (Spilogale putorius), striped skunk (Mephitis mephitis), American badger (Taxidea taxus), jackrabbit (Lepus sp.), cottontail rabbit (Sylvilagus sp.), black -tailed prairie dog and various rodent species. The Project Area also supports a variety of raptors and migratory birds such as short -grass prairie species including: thrashers, thrushes, shrikes, prairie sharp - tailed grouse, vireos, warblers, wrens, larks and buntings (discussed in more detail below in Section 5.9.4.3.4). A summary of the information provided by the data sources above is presented below. CPW Information A review of CPW's Species Activity Mapping (SAM) occurred for Project Area wildlife distribution information (CPW, 2017). Table 5-8 provides SAM information on wildlife distribution for the Project.

The Fritz Knopf Prairie: Pawnee Grassland East PCA has a High Biodiversity Significance rank (B3). The site is considered a PCA primarily for McCown's Longspur, Chestnut -collared Longspur and Mountain Plover and includes native grasslands surrounding known occurrences of rare grassland birds. Major agricultural areas to the north, south, east and west were excluded. The Sidney Draw South and Sidney Draw West PCAs have a General Biodiversity Interest rank (B5) and is described as short grass prairie currently used for livestock grazing and some dry wheat farming. These areas contain extant and historical occurrences of the state vulnerable (G4/S3B) ferruginous hawk (Buteo regalis). Chalk Bluffs north has a High Biodiversity Significance rank (B3) due to the occurrence of a vulnerable plant community Scarp (Juniperus scopulorum / Schizachyrium scoparium) Woodlands. Leeward Renewable Energy Development, LLC 5-46 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) The CNHP data also indicates various Element Occurrences (EO). An EO represents a location in which a global or state rare species, subspecies, or unique natural community tracked by the CNHP is, or was, present. An EO has continued (or historic) presence and/or regular recurrence at a given location and has practical conservation value. The EO's within the Project Area are chestnut -collared longspur, ferruginous hawk, McCown's longspur, mountain plover and scarp woodlands. Three species were identified in the CNHP observation data, burrowing owl, chestnut -collared longspur and prairie falcon (CNHP, 2018). These observation points were based on surveys conducted by the Rocky Mountain Bird Observatory in 2004 and 2006. Wildlife Impacts and Mitigation Permanent impacts to wildlife from construction and operation of the Project may include potential injury and/or mortality due to vehicle collisions or crushing of animals in these areas. There will be permanent habitat loss where infrastructure such as wind turbines, transmission structures, substations, and permanent access roads are constructed resulting in loss of vegetation. Temporary disturbance from construction activities for turbine pads, collection line paths, temporary access roads, and other associated temporary work areas may result in displacement and/or avoidance of the area by many species and habitat loss in the form of vegetation removal and soil disturbance. Temporary disturbance areas will be re -graded and re -vegetated with an appropriate native seed mix upon completion of construction. The Project may displace some individual wildlife during construction as a result of construction noise and activities. Wildlife displacement would be temporary and would not significantly impact these species. In addition to post -construction reclamation, wildlife habitat impacts will be minimized through the implementation of a SWMP to control erosion of soils, and sediment and other pollutants that could negatively impact water quality. The SWMP will include best management practices to be installed before, during and after construction until final stabilization. Impacts to most mammals will be minimal due to the existing land use in the area, however winter range for big game species such mule deer, white-tailed deer, and pronghorn is present. Measures should be taken in winter range to avoid additional stress on these species such as spatial and/or temporal buffers in coordination with CPW. Most mammals will avoid the area during the construction timeframe when activity levels are greatest and eventually habituate to the Project following construction completion. The risk of injury and mortality to bats will be a potential concern resulting from the Project due to reported mortalities from strikes by wind turbines at other projects. However, a 5 -year bat mortality study at the Foote Creek Rim Wind Power Project in Carbon County, Wyoming resulted in low estimated Leeward Renewable Energy Development, LLC 5-47 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) annual bat mortality per turbine (1.34 bats/turbine) for all study years combined (PacifiCorp, 2003). Impacts to bats are not anticipated to be significant considering the lack of historical bat observation data and identified habitat for bats in the Project Area. Leeward will continue to follow WEG through the development of the Project and during post -construction evaluations. Habitat for reptile and amphibian species is limited within the Project Area. Reptile species would likely inhabit rocky outcrop features within the Project Area. Suitable habitat will be identified for these species prior to construction and impacts will be minimized where possible. Impacts to reptiles are expected to be minimal. Bird species could be impacted during the breeding season as a result of construction activities causing disruption of reproductive behavior (e.g., incubation, fledging periods, establishment of breeding pairs, and territories). The bird breeding season should be avoided to minimize these impacts; however, if the nesting season cannot be avoided pre -construction raptor and migratory bird surveys will be conducted within the Project Area to identify nests and breeding activity. Any new nests will be appropriately buffered, and activities avoided in those areas until the young birds have fledged in coordination with USFWS and CPW. The Project could also impact bird species in the form of injury and mortality resulting from collisions with wind turbines and transmission line structures. Impacts from collisions can be minimized during siting of wind turbines and transmission lines by avoiding; habitat where birds concentrate, such as wetlands or ponds; and areas or features that are known to attract raptors. Transmission lines also pose a risk by electrocution to bird and raptor species. Leeward will continue to consult with USFWS and CPW during the development phase to identify hazards to birds and establish mitigation measures to minimize impacts on these species. Leeward will design the Transmission Facilities in accordance with Avian Power Line Interaction Committee (APLIC) guidelines (APLIC, 2006) to protect bird species from potential collision and electrocution. Further discussion on impacts and mitigation for migratory birds and raptors is included below in Section 5.9.4.3.3 and 5.9.4.3.4. Leeward will implement the following measures to mitigate for potential impacts to wildlife species: If construction occurs during nesting season, additional raptor nest surveys will be conducted prior to construction to confirm locations and species nesting in the area. Construction timing constraints near known active nests will be implemented whenever feasible to avoid disturbance to nesting raptors. Coordination with USFWS will continue if it is determined construction activities could potentially impact the productivity of a golden eagle nest. Leeward Renewable Energy Development, LLC 5-48 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) • A presence absence survey will be conducted for mountain plovers (please see discussion in Section 5.9.4.3.2) within the Project Area prior to construction to facilitate avoidance of nesting plovers. • Monitoring of the facility will document fatalities to birds and bats as a result of collisions with turbine blades or other facility infrastructure. Two years of post -construction fatality surveys will be conducted within the facility site. The fatality surveys may be conducted in non-consecutive years based on recommendations from wildlife biologists. Communications with the USFWS and CPW will continue and collisions will be reported to the agencies. Threatened and Endangered Species The Endangered Species Act of 1973 (ESA) affords legal protection to those species and their habitats determined to meet the specified criteria for listing by the Federal government as either threatened or endangered. The ESA defines a federally endangered species as, "any species which is in danger of extinction throughout all or a significant portion of its range." According to the USFWS IPaC inquiry from October 12, 2018, there are 9 federally protected species which may occur in the vicinity of the Project or have the potential to be impacted by certain Project activities (USFWS, 2018b; Table 5-9). No USFWS designated critical habitats are mapped within the Project Area (USFWS, 2018c). Table 5-9 provides the potential federal threatened and endangered species identified by IPaC as potentially within the Project or vicinity and whether or not habitat for that species is present in the Project Area. Following Table 5-9 is a discussion of each species with potential impacts and mitigation measures Leeward will implement to minimize impacts of the Project.

The four species outlined in Table 5-9 with potential to occur in the Project Area include, Colorado butterfly plant (Gaura neomexicana var. coloradensis), Ute ladies' tresses (Spiranthes diluvialis), western prairie fringed orchid (Platanthera praeclara), and whooping crane (Grus americana). The Project Area does not contain suitable habitat for the Preble's meadow jumping mouse (Zapus hudsonius preblei), Mexican spotted owl (Strix occidentalis lucida), interior least tern (Sterna antillarum), pallid sturgeon (Scaphirhynchus albus), or piping plover (Charadrius melodus) based on desktop review of habitat range, presence, and location of critical habitat for each species. Therefore, the Project will have no effect on these species. The Project Area is within habitat and range for the Colorado butterfly plant and Ute ladies' -tresses. On May 7, 2018, the USFWS issued a proposed rule indicating the Colorado butterfly plant is proposed for delisting from the Federal List of Endangered and Threatened Plants due to recovery, however a final rule has not been issued (USFWS, 2018d). Although the Project Area is within habitat range for these two species of plants, no historical observation data indicates they occur in the Project and no surveys to confirm whether these species or their habitat are present have been conducted. Western prairie fringed orchid occurs in moist tallgrass prairie areas and sedge meadows. Habitat range for this species is throughout the Project Area. Impacts to these three threatened plant species will include loss of individual plants and populations during vegetation clearing and earthwork for permanent and temporary facilities. As a result of earthwork, topsoil containing the native seedbed will be removed and lost if topsoil is not preserved and used in restoration of temporary work areas. If the temporary disturbance areas are not properly restored and protected from invasion by noxious weeds, the plant community could possibly shift and result in habitat which excludes these species. In order to mitigate the impacts of the Project on threatened plant species, surveys will be conducted to determine if these species or habitat are present in areas proposed for construction and may be adversely impacted. Surveys for Ute ladies' tresses within the Project Area will be conducted during the first week of August in conjunction with flowering periods of this species, and possibly earlier in areas that are not well shaded. Surveys for the Colorado butterfly plant and habitat will occur during June to September to coincide with the flowering period of this species or as recommended by USFWS. Western prairie fringed orchid surveys will occur during the flowing period, mid -June to late July. Leeward Renewable Energy Development, LLC 5-51 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Should these plant species be present in the Project Area, Leeward will take measures to avoid siting construction in habitat for these species to avoid loss of plants, seedbed, and habitat. If the habitat cannot be avoided, Leeward will coordinate with USFWS on appropriate mitigation measures to protect these species and minimize impacts. These measures may include reclamation and reseeding activities to restore habitat for these species, removal and preservation of topsoil for use in restoration of temporary disturbance areas, implementation of noxious weed control measures, and a SWMP to preserve the soils in the habitat area. The Project is within the habitat range of whooping crane, but the only self-sustaining and wild population of whooping cranes nests at and near Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada. Birds from the population migrate during spring and fall through the Great Plains of North America and winter along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands. The migration occurs throughout a 2,400 -mile long by 200 -mile wide corridor spanning Saskatchewan, eastern Montana, North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas. The Project Area is over 100 miles west of the whooping crane migration corridor and 95% percent of whooping crane sightings are within the mapped corridor. Whooping crane sighting may exist outside of the migration corridor, but it is rare. Therefore, the Project is not likely to adversely affect the whooping crane. State Protected Species The Wildlife Act and Parks Act are potentially applicable to the Project. The legislative basis for the Wildlife Act of CPW is found in CRS 33-1-101 (1) which states, "it is the policy of the State of Colorado that the wildlife and their environment are to be protected, preserved, enhanced and managed for the use, benefit, and enjoyment of the people of this State and its visitors." The Colorado list of species of concern is an element of the State Wildlife Action Plan (SWAP, 2015) for non -game species managed under State Wildlife Grants program (Title IX, Public Law 106-553 and Title 1, Public Law 107-63). CPW has responsibility for periodically reviewing this list and providing recommendations for revisions as needed. In addition to periodic updates to the species protection list, CPW develops guidelines for protecting species of concern. CPW has developed guidelines for protecting raptor species through nest disturbance buffers and seasonal restrictions. These restrictions will apply to the development of the Project (CPW, 2008a). Leeward Renewable Energy Development, LLC 5-52 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) The CPW state listed species table was consulted to determine species with state status likely to inhabit the Project Area and are outlined below in Table 5-10. CPW was contacted regarding their concerns for the Project, however no response has been received to date. The CPW databases and the CNHP were used to determine species of concern that could potentially occur in the Project and surrounding area.

Two ground -based lek surveys for plains sharp -tailed grouse were conducted at the proposed Project and neighboring Cedar Creek I Wind Farm during early and late April 2018. Surveys were conducted along public roads, turbine access roads, and private access roads in grazed and ungrazed grassland areas. A total of 68 survey points were included in the proposed Project Area and 106 survey points in the Cedar Creek I Wind Farm for a total of 174 survey points. Over the course of the surveys, 7 plains sharp -tailed grouse leks were identified and 15 non-lek observation points were recorded where plains sharp -tailed grouse (or greater prairie chicken [Tympanuchus cupido]) were seen, but no lekking behavior occurred. The leks within the Project were identified in the southwest portion of the Project, but observations were made throughout the Project Area. Leeward Renewable Energy Development, LLC 5-53 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Western EcoSystems Technology, Inc. (WEST) mapped black -tailed prairie dog (BTPD) colonies in and around the Project. BTPD colonies in the area may be an attractive prey source for golden eagles and mapping of the colonies during May 2018 assisted in understanding where the species occur, but also as prey sources for golden eagles. BTPD colony data mapped by CPW in 2015 and from colonies recorded during raptor nest surveys conducted in March 2018 were used as targets for the ground surveys. BTPD colonies were confirmed through visual observation if colonies were active, if the mapped areas appeared to be accurate or not and any other sensitive species in the area were also noted. Of a total of 33 total colony locations mapped by CPW and WEST, 20 were visible from the public roads. Five colonies were confirmed active, eight were confirmed inactive, and the remaining colonies unknown due to lack of visibility or sufficient visual evidence. No BTPD colonies were observed within the Project and the nearest colony was approximately 0.6 mile outside the Project to the south. Black -tailed prairie dogs do not appear to inhabit the Project Area, but areas in proximity to the Project. Burrowing owls (Athene cunicularia) are highly associated with prairie dogs because burrowing owls use prairie dog burrows for nesting and roosting. No BTPD colonies were previously documented by CPW and WEST and included in the mapping survey of the Project Area, however there was one burrowing owl observation documented by CNHP along the Project's western boundary. Since the BTPD were identified outside the Project Area, the possibility of burrowing owls inhabiting the Project are less likely, but burrowing owls could still utilize the Project for foraging or utilize any abandoned BTPD burrows or those of other species. The Project could result in impacts to burrowing owls including direct injury or mortality as a result of ground disturbance and vehicles during construction. Burrowing owls could be permanently and temporarily displaced and may experience impacts on reproductive success if spatial and temporal buffers are not adhered to if owls inhabit areas proposed for disturbance. Surveys should occur prior to construction to confirm if burrowing owls inhabit the Project Area. If construction were to occur during the burrowing owl nesting season (March 15 through October 31), a preconstruction survey will be conducted in suitable habitat (active and/or abandoned prairie dog colony) within the Project Area in accordance with CPW's Recommended Survey Protocol and Actions to Protect Nesting Burrowing Owls (CPW, 2008b). Active nests of burrowing owls will be buffered by 150 feet in which no human encroachment will occur until young have fledged. Mountain plovers (Charadrius montanus) arrive at their breeding grounds in Colorado during the month of March. Habitat for mountain plovers include prairie grasslands, arid plains, and fields. Short -grass prairies which are grazed by prairie dogs, bison and cattle, and overgrazed tallgrass and fallow fields are Leeward Renewable Energy Development, LLC 5-54 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) chosen for nesting. Nests can be found on bare ground which is eventually built up with rootlets and grass surrounding the nest. Mountain plovers nesting in the Project Area will potentially be impacted by construction during the breeding season in areas proposed for disturbance. Mountain plover nesting season should be avoided to minimize these impacts; however, if the nesting season cannot be avoided pre -construction surveys should be conducted within the Project Area to identify nests and breeding activity. Any new nests will be appropriately buffered, and activities avoided in those areas until the young birds have fledged in coordination with USFWS and CPW. The northern pocket gopher (Thomonmys talpoides) inhabits grassland, shrubland, farmland, and cattle pastures in upland areas above 5,000 feet in the eastern plains. The northern pocket gopher may inhabit the Project Area in portions of the Project Area above 5,000 feet. Swift foxes are likely present due to the short- or mixed -grass prairie with flat to gently rolling terrain and low -growing sparse vegetation that allows for good mobility and visibility. Prey base, long viewing distances to avoid predators, and firm, friable soil suitable for dens are also essential for good swift fox habitat. The northern pocket gopher and swift fox may experience direct impacts in the form of injury and mortality as a result of collisions or crushing by vehicles and equipment. These species will be displaced from their habitat and will experience habitat loss in permanent disturbance areas. Northern pocket gopher and swift fox will likely be temporarily displaced and avoid the area during construction but will habituate to the Project and continue thriving in the area. Habitat for these species will be identified during pre -construction surveys and avoided to the extent possible during construction activities. Reclamation of habitat in temporary disturbance areas will allow for recovery of habitat for these species where present in proposed construction areas. Eagles The Bald and Golden Eagle Protection Act enacted in 1940 (BGEPA) prohibits anyone, without a permit issued by the Secretary of the Interior, from taking bald or golden eagles, including their parts, nests, or eggs. The BGEPA defines "take" as pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, molest, or disturb. In addition to immediate impacts, the definition also covers impacts that result from human -induced alterations initiated around a previously used nest site during a time when eagles are not present, if, upon the eagle's return, such alterations agitate or bother an eagle to a degree that interferes with or interrupts normal breeding, feeding, or sheltering habits, and causes injury, death, or nest abandonment. Leeward Renewable Energy Development, LLC 5-55 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Golden eagles (Aquila chrysaetos) are widely distributed utilizing a wide range of habitats including grassland and agricultural habitats similar to that within the Project Area. Golden eagles also forage on a wide variety of small- and medium-sized mammals, including rabbits, hares, prairie dogs, ground squirrels, and marmots. Aerial surveys for eagle nests within 10 miles of the adjacent Cedar Creek I Wind Farm (of which most of the survey area overlapped the proposed Mountain Breeze Wind Facility) were conducted in February and May 2017. A second round of surveys for the Mountain Breeze Wind Facility were performed in March and May 2018. During the surveys, potential nesting habitat such as trees, power poles, rocky outcrops, and cliff faces were examined for stick nest structures, and previously detected golden eagle nest locations were visited during the February and March surveys in 2017 and 2018. Potential prey sources for golden eagles such as prairie dog colonies and waterfowl concentrations were also recorded during the February 2017 and March 2018 surveys. The surveys in May 2017 and 2018 consisted of targeting previously identified nest locations. The February 2017 survey documented one active golden eagle nest (8.8 miles northwest of the Cedar Creek I Wind Farm boundary) and another 135 inactive nests, 28 of which were large stick nests on cliffs that could be used by golden eagles. The May 2017 survey showed increased nesting activity, including four active golden eagle nests and 98 inactive nests, of which 23 were large stick nests that could be used by golden eagles. One of the four active golden eagle nests were within the Cedar Creek I Wind Farm boundary or one -mile buffer. The golden eagle nest that was detected in February was still active during the May survey, with an adult observed on the nest. Two golden eagle nests in known locations from previous years that were inactive in February were active with adults observed at the nests in May. The March 2018 survey of the Mountain Breeze Wind Energy Facility detected three active golden eagle nests and 51 inactive nests. Of the 51 inactive nests, 46 were large stick nests on cliffs that could be used by golden eagles, although many were in poor condition. The three active golden eagle nests were in previously recorded locations to the south and east of the Project. The nearest golden eagle nest was about 4.0 miles south-southwest of the Mountain Breeze Wind Energy Facility boundary. Other golden eagle nest locations known from surveys during previous years were not occupied during the March 2018 survey. During the May 2018 survey, four active golden eagle nests were detected. A total of 54 inactive nests were documented, 39 were large stick nests that could be used by golden eagles. One active golden eagle nest which was active in March was no longer active in May. All four active golden eagle nests were observed to have an adult on the nest, and chicks were seen in one of the nests. The nearest active golden eagle nest to the Mountain Breeze Wind Energy Facility was 2.6 miles to the west. Other active nests were between 4.7 and 7.4 miles from the boundary of Mountain Breeze Wind Energy Facility. Leeward Renewable Energy Development, LLC 5-56 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Attractive prey sources for golden eagles in the area may be the BTPD. As discussed above in Section 5.9.4.3.2, BTPD colonies were mapped in May 2018 to identify prey sources for golden eagles. The survey results identified five colonies which were confirmed active, eight confirmed inactive, and the remaining colonies unknown due to lack of visibility or sufficient visual evidence. Furthermore, no BTPD colonies were observed within the Mountain Breeze Wind Energy Facility and the nearest colony was approximately 0.6 mile to the south. The Mountain Breeze Wind Energy Facility does not appear to support a BTPD prey base for golden eagles, but the surrounding area provides habitat to support BTPD as a prey species for golden eagles. Surveys of the Cedar Creek I Wind Farm, Mountain Breeze Wind Energy Facility, and vicinity did not identify bald eagles (Haliaeetus leucocephalus) or potential nests of bald eagles. No historical observation data was identified for bald eagles and the Project is lacking large bodies of water such as lakes, reservoirs, and rivers critical for foraging and large trees in which to build nests. The Project is not likely to affect bald eagles. Golden eagles within the Project Area could experience impacts resulting from construction activities in the form of loss of habitat, disruption of breeding behavior, potential strikes or collisions with wind turbines, and collisions or electrocutions with transmission facility structures. Survey results indicate golden eagles inhabit the Project Area. Leeward will coordinate with USFWS and CPW regarding mitigation measures for eagles. Mitigation and minimization measures agreed to by Leeward will lessen the Project's impacts on golden eagles. Leeward is also committed to conducting post -construction fatality surveys documenting any bird collisions within the facility site. Communications with the USFWS and CPW will continue post -construction and collisions will be reported to the agencies. USFWS and/or CPW nesting and spatial buffers will be implemented near known identified eagle nests to reduce Project impacts on golden eagles and allow construction to proceed. Pre -construction surveys during the appropriate timeframes for nesting golden eagles will be conducted to identify any new nests which may be impacted by the Project. Golden eagle courtship in Colorado may begin as early as March with young being hatched as early as mid -April, however some pairs will nest later with young still at nests in mid -July (CPW, 2018).. Raptors and Migratory Birds Raptors and Migratory birds protected under the Migratory Bird Treaty Act of 1918 (MBTA) have the potential to occur in the Project Area. Raptors and migratory birds occur in every type of habitat that the Project crosses. Leeward Renewable Energy Development, LLC 5-57 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Suitable habitat exists for raptors including red-tailed hawk (Buteo jamaicensis), ferruginous hawk, prairie falcon (Falco mexicanus), golden eagle, and Swainson's hawk (Buteo swainsoni). Aerial raptor nest surveys were conducted early in Leeward's Project development. Surveys were conducted on February 25 and 26, 2017 and May 2 and 3, 2017, then again on March 10 to 12, 2018 and May 8, 2018 for two years of study. The aerial surveys were designed to detect raptor nests within one mile of the Project boundary and any eagle nests within 10 miles of the Project boundary. Any areas that were not previously surveyed due to Project development changes will be completed in subsequent surveys. In addition to raptors, birds likely to occur within the vicinity of the facility include short -grass prairie species such as thrashers, thrushes, shrikes, prairie sharp -tailed grouse, vireos, warblers, wrens, grosbeaks, sparrows, towhees, blackbirds, larks, and buntings. Raptors and Migratory birds may be impacted due to collision -related mortality. Studies on other wind energy projects in similar environments to the proposed site have not shown large numbers of avian fatalities. The risks of fatalities from wind energy facilities are minor when compared to other fatality risks to birds such as house cats and collisions with vehicles, buildings, and windows. Impacts from collisions of both wind facilities and transmission lines can be minimized by following recommended wind energy facilities siting practices (USFWS 2012) such as avoiding: bird migratory pathways; habitats where birds concentrate, such as wetlands or ponds; and areas or features that are known to attract raptors. The Project is not located within a major migratory corridor with a migratory pathway, and there are very limited wetland and surface water features that might draw waterfowl or other species on a seasonal basis. There are some escarpments that run east to west within the Project Area, as well as the occasional tree or shelter belt which could provide suitable nesting habitat. The removal of vegetation in construction areas will temporarily reduce foraging, shelter, or nesting habitat for some migratory bird species. In order to mitigate potential adverse effects of the Project on nesting birds, an effort will be made to schedule vegetation clearing activities for a timeframe outside of the migratory bird breeding season, generally April 1 through August 31. If vegetation clearing were to occur between April 1 and August 31, a survey for the presence of nesting migratory birds will be conducted prior to clearing. If active nests are found, mitigation measures may be required to protect the nest until nesting activity concludes. In addition, Leeward will implement the CPW recommended buffers zones and seasonal restrictions for raptor species (CPW, 2008a). Leeward Renewable Energy Development, LLC 5-58 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Set -backs have been applied to all raptor nests identified during the 2017 and 2018 surveys to minimize the impact of the Project. Additional raptor nest surveys will be conducted prior to construction to locate new nests and relocate previously identified nests. Setbacks to newly identified nests will be applied based on species according to USFWS and CPW guidelines. Where new setbacks cannot be applied due to economic or other constraints, alternative mitigation measures will be evaluated in consultation with CPW and USFWS. In addition to the studies that have already been conducted, Leeward has committed to the following measures to mitigate for potential impacts to wildlife species: • Additional raptor nest surveys will be conducted as feasible prior to construction to confirm locations and species nesting in the area. • Construction timing constraints near known active nests will be implemented whenever feasible to avoid disturbance to nesting raptors. • Coordination with USFWS will continue if it is determined that construction activities could potentially impact the productivity of a golden eagle nest. • A presence or absence survey will be conducted for mountain plovers within the proposed wind energy facility site prior to construction to facilitate avoidance of nesting plovers. • Monitoring of the facility will document fatalities to birds and bats as a result of collisions with turbine blades or other facility infrastructure. Two years of post -construction fatality surveys will be conducted within the facility site. These surveys may be conducted in non-consecutive years based on recommendations from wildlife biologists. Communications with the USFWS and CPW will continue and collisions will be reported to the agencies. Critical Wildlife Habitat There are no critical wildlife habitat areas identified within the Project Area (USFWS, 20I 8c). The Project is within the vicinity of the Pawnee National Grasslands, but federal lands were avoided during siting of the Project. 5.9.4.4 Public Outdoor Recreation Areas The nearest public outdoor recreation area to the Project is the Pawnee National Grasslands. The Pawnee National Grasslands is administered by the USDA FS as a grassland conservation area, but provides public recreation opportunities such as hiking trails, mountain bicycling, hunting, fishing, wildlife viewing, and interesting landmarks such as the Pawnee Buttes. Pawnee Buttes are sedimentary rock formations, one half mile apart, that rise 250 feet above the plains to an elevation of 5,375 feet. Leeward Renewable Energy Development, LLC 5-59 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Jackson Lake and North Sterling Reservoir are located approximately 35 miles to the south and east of the Project respectively provide boating, fishing, hunting, hiking, biking, and picnicking opportunities to the recreating public. In addition to outdoor recreation, North Sterling Reservoir closes in November for waterfowl hunting opportunities. The Project was sited to avoid the Pawnee National Grasslands, therefore no impacts from the proposed Project are anticipated and no response was received from the USDA Forest Service regarding concerns for the Pawnee National Grasslands as a result of the proposed Project. Due to the distance of the Project from Jackson Lake and North Sterling Reservoir, the Project will have no impacts on recreation in these parks. 5.9.4.5 Unique Areas of Geologic, Historic, or Archaeological Importance To determine previously recorded cultural resources (archeological sites, historic structures, cemeteries, etc.) that occur within or immediately adjacent to the Project Area and to determine areas that have been previously inventoried, Class I archaeological records searches were conducted with available data bases and appropriate file curation facilities. The full desktop cultural and paleontological resources memo is included in Appendix I. The records search returned four previously conducted surveys within the study area. There are three previously recorded historic -age sites, two historic water control structures and one historic habitation. All three sites have been determined to not be eligible for listing on the National Register of Historic Places (NRHP). A file search conducted in the NRHP and SRHP data bases indicate that there are no sites listed on either of the registers within the Project Area (National Park Service, 2018; OAHP, 2018b). There are no Centennial Farms located within the Project Area. A single cemetery, the Higby (Sunnyside) Cemetery, is located at the southwest corner of the intersection of County Road 119 and 134 (USGS, 1997). The cemetery contains 11 graves that date between 1911 and 1928 (Coloradogravestones, 2018). A structure within the Project Area is associated with the U.S. Air Force. This is a unit of the O -Flight of the 321" Missile Wing, and consists of structure O-2, a Minutemen III missile launch facility (University of Wyoming, 2018). The facility is located two -miles west of the intersection of County Road 119 and 134. In the same general area is an abandoned launch facility, located 0.6 miles west of the same intersection. There is also an abandoned military communication antenna base, located 1 -mile north of the intersection of County Road 111 and 136. Leeward Renewable Energy Development, LLC 5-60 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) No impacts to culturally or historically sensitive resources are anticipated. The construction footprint will be subjected to a Class III cultural resources survey prior to construction. The purpose of this survey is to locate cultural resources to inform the final siting stages of the proposed action. Each identified site must have at least a 100 -foot -setback from proposed development. Class III surveys will include the proposed area of potential effects for the wind turbines (e.g. project disturbance area) as well as 200 -feet -buffer around: each turbine, current access road that will be improved, new access roads, transmission lines, substations, and any other support facilities. Cultural sites and isolated finds located during the Class III survey will be evaluated for eligibility for the NRHP. Sites recorded more than 10 years ago will be re- evaluated. Previously inventoried sites with be evaluated. Sites will be recorded for formal OAHP site recording forms. Once the survey is complete a formal report describing the Project and the sites identified during the survey will be prepared. Previous paleontological studies conducted to the northeast (Nebraska) and to the south of the Project Area, suggest that vertebrate finds could be very common within the local badlands and drainage slopes. The vertebrate fossils from the Brule Member include specimens of reptiles (snakes, lizards, tortoises and turtles), fish (catfish and sunfish), and mammals (ancestral modern lineages: horses, dogs, cats, mustelids, camels, deer, rhinoceros, rodents, rabbits, insectivores, and marsupials and extinct lineages: brontotheres, entelodonts, oreodonts, hyaenodonts, sabertooth cats, and terrorbirds). These include partial finds as well as well -articulated skeletons of many of the larger mammals. The Project Area should be considered high for the potential of paleontological finds for three primary reasons: 1) the Brule Member of the White River formation has been known to contain a high occurrence of paleontological resources, however it varies in occurrence and predictability; 2) the Ogallala formation has been known to contain occurrences of paleontological resources, however it greatly varies in occurrence and predictability; and 3) Surface disturbing activities may adversely affect paleontological resources. The probability for impacting significant paleontological resources is moderate to high and is dependent on the proposed action. Mitigation plans must consider the nature of the proposed disturbance, such as the removal or penetration of protective surface alluvium or soils, potential future accelerated erosion, or increased ease of access that could result in looting. A detailed field assessment will be completed prior to construction. Two notable geomorphologic features in the study area are the Pawnee Buttes and the Chalk Bluffs. The Chalk Bluff escarpments are a series of ridges, steep hills, and siltstone rock outcrops often capped by sandstone. These escarpments, located on private land, are considered to be the northern boundary of the Colorado Piedmont. The best-known geomorphological feature in the survey area are the Pawnee Buttes. Leeward Renewable Energy Development, LLC 5-61 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) These two buttes rise to 5,275 feet (1,608 m). The tops of the buttes are only about 250 feet above the plains surface, but because of their isolation, they are a well-known landmark. Sediments from the Ogallala formation cap the buttes, with White River Group sediments in the lower portions. They have avoided the erosive forces that lowered the sediment layers of the surrounding areas, probably due to a slightly thickened or erosion resistant cap rock (Hazlett, 1998). Other Project geological features and impacts are discussed in Section 5.17.2. 5.9.5 Visual Aesthetics and Nuisance Factors (21-3-330.C.2.e) The area within view of the proposed Project is a rural setting consisting of flat to rolling landscape containing fields that are tilled, grazed grasslands, or CRP grasslands, which is characteristic of much of north central Colorado. The Project viewshed also contains DOD managed missile silos and the Pawnee National Grasslands. The lands surrounding the Project contain wind turbines existing within the neighboring Cedar Creek I Wind Farm. Visual simulations were prepared and are included as Appendix N, in order to better evaluate the potential impact of the Project on the landscape. Viewers in the immediate area will consist of residents who occupy farms and homesteads which are distributed along county and private gravel roads throughout the Project Area. These viewers will be most sensitive to changes in the visual landscape, however these residents have been conditioned to the visual changes created by wind turbines from the neighboring Cedar Creek I Wind Farm and the Cedar Creek II Wind Farm to the south and east. The key locations in which viewers may be sensitive to the presence of wind turbines and transmission line structures may include county and private gravel roads, farms, and homesteads. In order to mitigate the visual impacts of structures and facilities in the Project Area, Leeward will adhere to Weld County wind turbine setback requirements when siting turbines to maintain distance from property boundaries of residences (please refer to Table 5-6 in Section 5.6.10). The Project will not deteriorate existing viewsheds, unique landscapes, or other natural aesthetics. The landscape already has numerous wind turbines in operation from the existing Cedar Creek I Wind Farm, therefore the visual impact of the Mountain Breeze and Panorama Wind Energy Facility will not be a significant change from the existing conditions since the visual corridor has been previously impacted by wind turbines and existing development such as transmission line and oil and gas development. Furthermore, a majority of the landscape has been converted to agricultural land and the natural habitat in the area has been previously disturbed. Leeward Renewable Energy Development, LLC 5-62 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Following construction, temporarily disturbed areas will be returned to preconstruction contours; the topsoil will be replaced; and all remaining disturbed areas will be re -seeded according to Weld County and/or landowner requirements to minimize the visual impacts in the area (please refer to Section 5.17.4 for further discussion regarding visual impacts). During construction of the Project, there will be an increase in noise, vibration, and possibly odor from construction equipment. Any effects will be short-term during construction; however, some noise levels will still be noticeable from the Wind Energy Facility due to operation of the turbines. The noise levels associated with the Wind Energy Facility will conform to Weld County requirements for noise associated with the Project (please refer to discussion in Section 5.17.5 for further discussion regarding noise impacts). 5.9.6 Transportation (21-3-330.C.2.f) The following section describes Project impacts to transportation patterns, roads within the County, and improvements required to any roads to serve the Project adequately. 5.9.6.1 Wind Energy Facility Operation of the Wind Energy Facility will not generate a significant number of long-term daily trips. However, during the height of construction, over 100 construction workers will be employed during the course of the 12 -month construction period and will be traveling to various areas of the construction site each day. Furthermore, all of the materials for the Project will be transported to the site during construction by truck. These deliveries will consist of water, gravel, concrete supplies to on -site batch plants, turbine components, tower, and equipment deliveries. Conceptual construction routes and site access points are shown in Appendix A Figure 15, any updates will be provided, if needed, to the County prior to construction. The majority of the access to the Wind Energy Facility will be from Weld County. Project personnel will work with the Weld County Engineer to review road use during the construction activities and to develop a maintenance programs that will prevent the roads from dropping below agreed - upon quality levels. Concurrently with the 1041 permit from Weld County, Leeward plans to negotiate a mutually acceptable Road Maintenance Agreement with Weld County's Public Works Department to ensure roads are maintained and/or repaired. Under the Weld County agreement, Leeward will maintain county roads within the Project Area at all times during construction. Leeward Renewable Energy Development, LLC 5-63 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Prior to construction, Leeward will coordinate with Weld County, Colorado; Kimball County, Nebraska; and Laramie County, Wyoming to survey the county -owned roads so that the conditions of the county - owned roads leading to the Project site prior to construction can be established. During construction, so long as there continues to be heavy truck traffic to the Project, Leeward will keep an inventory of road repair material on or near the Project so any road damage can be repaired more quickly. Furthermore, Leeward will use commercially reasonable efforts to limit heavy truck traffic within the Project after a precipitation event. The Mountain Breeze and Panorama Wind Facility will use the existing Cedar Creek I O&M facility. Both scheduled and unscheduled maintenance will occur as needed. Scheduled maintenance will average approximately 10 to 20 visits per turbine per year. No adverse impacts to county roads or improvements are expected during commercial operations. There will be no staging or parking of vehicles or equipment on maintained county roads. All such activities will make use of on -site locations and private ROWs. The turning radiuses for the county roads within the Project may need to be temporarily increased to allow equipment deliveries to safely enter and exit the Project and minimize any traffic congestions issues for the public. The increase in the turning radii should not have any adverse effect on the local use of the roads. After construction is complete, Leeward will restore the roads/turning radii to their pre - construction conditions unless alternative arrangements are agreed upon. Access to county roads will comply with all applicable County standards and permit requirements and will be placed at locations that have adequate sight distance in both directions and not below the crest of a hill or where physical obstructions are present. The off-street parking and loading zones will be surfaced with gravel or the equivalent and will be graded to prevent drainage problems. Construction zone and construction crossing signs adjacent to county roads will comply with the U.S. Department of Transportation (DOT) Federal Highway Administration (FHWA) Manual on Uniform Traffic Control Devices (FHWA, 2009). Proposed construction haul routes for the Project have been developed (Appendix A Figure 15) and final haul routes will be determined upon completion of the site layout, turbine model selection, and engineering design. The haul routes will be provided to the County for approval prior to construction. Table 5-1 1 provides the estimate of construction vehicle trips. During peak construction, the traffic hours Leeward Renewable Energy Development, LLC 5-64 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) are expected to be from 6:00 AM through 8:00 PM, depending on season, schedule, amount of daylight, etc. Following the completion of construction of the Project, there will be a significant decrease in the amount of traffic. Several workers will be driving to the site each day, with delivery trucks only for equipment replacement and repair as needed. Operation and maintenance traffic typically peak during scheduled maintenance routes at 1 month, 6 month or 12 -month intervals, as determined by the wind turbine manufacturer and the O&M staff. The traffic hours typically will be from 7:00 AM to 7:00 PM, depending on season, schedule, amount of daylight, etc. Table 5-11: Transmission Facilities Typical Construction Personnel and Equipment Per Wind Facility Project Activity Number of Round Trips (approximate) Equipment Duration Hauling gravel, cement, and aggregate — 1,000 Heavy trucks and semis 4-6 months Hauling water - 500 Heavy trucks 6-8 months Hauling wind turbine components —200 Semis and oversized loads 4-6 months Hauling concrete — 300 Concrete mixers 3-5 months Worker travel 1,000 Light duty trucks 10-12 months Tracking pads will be used as necessary at all major construction locations where there is heavy traffic coming from the site onto a county road. The purpose of the tracking pads is to keep excessive mud and debris from leaving the site and being tracked on the county road. 5.9.6.2 Utility/ROW Permit A Weld County ROW permit (or permits) are required for the use of crossing a Weld County ROW. Leeward anticipates having buried collections lines across the intersection of County Roads 1 1 1 and 134; the intersection of County Road 115 and 138; and others may be necessary. The permits will be in place prior to any work being done within the ROW. 5.9.6.3 Special Transport Permit A Weld County Special Transport Permit for transporting the overweight or over width items using county roads or ROWs will be obtained prior to beginning work. Leeward Renewable Energy Development, LLC 5-65 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.9.6.4 Transmission Facilities The Transmission Facilities will not generate any daily trips during long-term operation if the facility is operating as planned. There may be times when repairs or maintenance will be conducted that may require more frequent trips; however, the probability of this occurrence is expected to be very low. Regular patrols will be conducted to inspect the facilities in accordance with the owner's maintenance schedule. Approximately 20-30 construction workers will be employed during the course of the approximately 6 -month construction period. The maximum number of construction workers at any one time will be approximately 30. No adverse effects on county roads are anticipated. Leeward will work with the Weld County Public Works Department to determine the appropriate construction method for each county road crossing. All mobile construction equipment will be certified to operate on Interstate highways. 5.9.7 Less Damaging Alternatives See section 5.12 and 5.13 for more information on the alternative's analysis. 5.10 Long -Term Effects from the Project upon Physical and Socioeconomic Development (21-3-330.B.8) Future physical development of the Project Area will not likely be affected. The Project Area is located within a sparsely populated, largely agricultural area. The nearest town, Grover, Colorado, consists of 153 residents (CO HomeTownLocator, 2018). The Project Area is unlikely to be in an area slated for intensive residential, commercial, or industrial development. No residents will be displaced as a result of the Wind Energy Facility or Transmission Facilities. The Project is sited within an area established by the state of Colorado Economic Empowerment Zone, within which economic development is encouraged. The Project will represent an increase of approximately 17 million to the county tax receipts over the life of the projects. The Project will create additional revenue in the form of royalties for the 43 property owners with wind turbines located on their property. The 8 property owners granting Leeward easement rights for the Project's interconnection Transmission Facilities will also receive option and lump sum easement payments. There will be no adverse socioeconomic impacts associated with the Wind Energy Facility. The Project, including construction of the associated Transmission Facilities and substation will employ over 120 people during the construction phase and approximately 45 to 60 direct full-time positions through the Leeward Renewable Energy Development, LLC 5-66 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest - Application Requirements (21-3-330) entire Project's operating life (including existing Cedar Creek I employees). The proposed Wind Energy Facility will have no negative impact on regional unemployment rates. There will be a long-term economic benefit to Weld County by introducing increased activity and spending dollars into the economy. In addition to creation of jobs (both during construction and commercial operations) and property taxes, the Project will create demand for local goods and services both during construction and commercial operations. Economic benefits to community businesses are relative to the amount of income spent in the local economy on goods and services by the larger temporary and smaller permanent workforce associated with the Project. The local economy is likely to experience an increase in economic activity, as well as an increase in sales tax revenue directly resulting from the construction and operation of the Project. The Wind Energy Facility will produce electricity from the wind which is not subject to fluctuating fuel prices and is considered stable. Furthermore, the electricity that is produced does not consume valuable water supplies, nor does it create air or water pollutants. Finally, electricity is a form of energy that is not easily stored; the grid operator has the challenge of keeping the supply of electricity balanced with the demand for electricity throughout each day and throughout the year. To maintain this balance between the supply and demand for electricity, the grid operator actually reduces the output of fossil fuel generating facilities when the wind blows at a sufficient velocity to produce electricity to maintain the balance between supply and demand. As the fossil fuel generators are scaled back to accommodate the wind facility, the fuel and water consumption, wastewater effluents and air emissions from the fossil fuel plants are all reduced. Unlike oil and gas reservoirs, the supply of wind will not deplete or diminish over time. In addition to local economic benefits, the Wind Energy Facility provides a substantial environmental benefit to the region. The Wind Energy Facility will generate a clean, affordable, efficient, and renewable energy source for the region. Only land surrounding the base of the wind turbine or transmission facility structures will be removed from agricultural operations. Land between structures will remain available to farming and ranching or other operations that do not interfere with safe and reliable operation of the Wind Energy Facility or Transmission Facilities. Leeward Renewable Energy Development, LLC 5-67 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.11 Mitigation of Adverse Impacts and Maximization of Positive Impacts (21-3- 330.B.9) Practical efforts will be made to restore disturbed land to its original contour and to restore natural drainage patterns within the Project Area. Disturbance to land during construction activities will be kept to minimal levels feasible because revegetation can be problematic in Weld County's semi -arid climate. All practical efforts will be made to re-establish vegetation in disturbed areas. Leeward's Standard Construction Mitigation Practices (Appendix G) address site reclamation of disturbed areas and other mitigation practices. Leeward will continue coordination with CPW and USFWS to develop appropriate mitigation measures that are compatible with Project goals and will minimize impacts to wildlife within the Project Area. 5.12 Non -Structural Alternatives (21-3-330.B.10) The alternative of not building the facility will fail to fulfill the Project's objective to provide adequate energy supplies to regional utilities. This area was selected for the proposed Project because of its superior wind resources and to provide an opportunity to more fully utilize the transmission infrastructure that was built for the existing Cedar Creek Wind Farms. Moving the wind facility to another location will result in a higher cost of electricity due to moving away from an area of high electrical production due to the available wind resource present. A different Project location may also result in additional costs associated with construction of transmission infrastructure. Additionally, the Project landowners will lose the opportunity to collect long-term lease payments from the placement of turbines on their land, and Weld County might lose the opportunity to benefit from the job creation, additional property taxes, and increased demand for goods and services. In addition, other alternatives to meet the renewable energy mandate associated with Amendment 37 will be necessary. In practice, these alternatives will be problematic because other renewable resources in sufficient quantities and at an acceptable cost profile are limited, or they will entail construction of other similar large-scale wind energy facilities elsewhere in Colorado. There are no non-structural alternatives that will accomplish the purpose and need for the Transmission Facilities and overall Project. If the Project is not built, Colorado utilities will be required to seek other projects to adequately increase their energy supplies to customers to fulfill the renewable energy mandate associated with the passing of Amendment 37. This is not an acceptable alternative as the purpose and need of the Project will not be met and Weld County will lose all of the Project benefits. Leeward Renewable Energy Development, LLC 5-68 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.13 Structural Alternatives (21-3-330.B.11) The dependency of a wind energy facility upon consistent wind speeds and appropriate topography determines the location of the Wind Energy Facility. Alternative types of energy generation facilities such as coal or natural gas are not considered as renewable resources and will not meet the objective associated with Amendment 37. Leeward considered feasible transmission line alignments and ultimately proposed an alignment that was economically sound and environmentally compatible with existing environmental conditions. The alignment also is compatible with future Weld County land use plans and acceptable to the jurisdiction it crosses. The proposed routes for the Transmission Facilities are located entirely in Weld County as shown in Appendix A Figure 2. The final transmission line routes will be provided to the County after final design is complete and prior to construction. The proposed route for the Mountain Breeze Transmission Facility will include approximately 11 miles of new single circuit 230 -kV transmission line construction and the Panorama Transmission Facility will include approximately 15 miles of 115 -kV transmission line construction. Both facilities will transmit power from the Project to the proposed interconnection sites at Junction Switchyard and Redtail Substation or similar facility. The ROW for the Transmission Facilities is 180 feet. The Transmission Facilities will cross numerous unnamed intermittent and ephemeral drainages. The routes were selected based on land acquisition issues and engineering and design goals. In general, areas of sensitive natural environments, including riparian area, water bodies, and areas of potentially suitable habitat for threatened and endangered species or species of concern will be avoided where possible. 5.14 Air and Water Pollution Impacts and Control Alternatives (21-3-330.B.12) 5.14.1 Air Pollution Impact and Control Weld County responds to air quality complaints through funding and authority from CDPHE which enforces state air quality regulations. In general, the primary sources of air emissions in Weld County include oil and gas exploration and productions, highway vehicles, biogenic sources, non -road mobile sources, construction and road dust, agriculture and other point sources (CDPHE, 2013). In 2013, there were 597,133 tons of air emissions in Weld County from all sources which equaled 17.7 percent of all sources of emissions in Colorado. Leeward Renewable Energy Development, LLC 5-69 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) During Project construction activities, there may be localized increases in air emissions, which could include hydrocarbons, carbon monoxide (CO), and NO„ associated with construction equipment and vehicle exhaust. Additional air quality impacts associated with the construction of the Project may occur from suspended particulates (dust) during site clearing and excavation activities and deposition from wind erosion on cleared construction areas. These impacts will be short-term as they will only occur during the active construction periods. Dust control measures will be implemented as necessary to suppress or prevent the emission of dust into the atmosphere during construction. An average of over 50 daily vehicle trips are estimated during construction. If excessive heavy truck hauling, concrete or materials cause dust problems for adjacent property owners, Leeward will provide an adequate dust suppressant (calcium or magnesium chloride) for approximately 300 feet from any residence. Prior to initiating Project construction, Leeward will submit a Dust Control Plan to the Weld County Department of Environmental Health for review. Air emissions resulting from Project construction activities will be permitted through the CDPHE Air Pollution Control Division (APCD), as required. The permit applications and evidence of Air Pollution Emission Notices (APENs) for the concrete batch plant and land development activities will be provided to Weld County prior to initiation of construction activities if required. Leeward will submit one APEN and Application for Construction Permit for land development for the Project and for the concrete batch plants. Based on the size of the Project Area, a Construction Permit and a 30 -day public comment period may be required. Proposed fugitive dust control will be specified on the application form. There are multiple intermittent, and ephemeral drainages within the proposed Project Area (Appendix A Figure 12). The implementation of standard construction, erosion, and sedimentation control practices will ensure the minimization of impacts to these drainages from increased turbidity, salinity, and sedimentation. These mitigation measures will include the use of one or more devices such as temporary berms, slope drains, diversion mounds, or sedimentation basins as appropriate. Measures will be implemented during construction to prevent spills of petroleum products or other pollutants that could impact surface water quality. There will be no direct impacts to water quality associated with the regular operation or maintenance of the Project. The Project will not create runoff in excess of historic site levels and will not change existing topography or adversely affect drainage. There will be no alteration in the pattern or intensity of surface drainage as a result of construction and operation of the Project. Leeward Renewable Energy Development, LLC 5-70 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Erosion and discharge of pollutants from the Project will be minimized through implementation of a SWMP designed to meet the requirements of the CDPHE Construction Storm Water Discharge Permit. The SWMP will include the use of stormwater retention ponds, sedimentation control measures, covering of exposed soils, and other established BMPs as specified in the permit requirements. 5.15 Design Alternatives - Access, Landscaping, and Architecture (21-3- 330.B.13) Design alternatives for access, landscaping, and architecture are not applicable to the Wind Energy Facility. Access to the Transmission Facilities will be provided by new and existing access roads within the 125 -foot -wide permanent ROW. Specific access through existing gates or through new locations will be agreed upon by Leeward and property owners. The access points will not require architectural or landscape treatments beyond restoring any disturbed land to its preconstruction condition. 5.16 New or Upgraded Services (21-3-330.B.14) Leeward anticipates there will be minimal adverse impacts to the community and local infrastructure. Project personnel are committed to reviewing county road use and engineering plans with the Weld County Engineer and repairing any damage caused by Leeward's contractors so that the county roads within the Project Area do not degrade below an agreed upon quality level. Similarly, Leeward has already begun consultation with the Pawnee and New Raymer-Stoneham Fire Protection Districts and will continue to work cooperatively with local fire/rescue departments to ensure the adequacy of fire/rescue resources to serve the facility. Since Leeward will not be a major employer, no significant additional demands are expected to be placed on other community services such as the school district. 5.17 Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts (21-3-330.B.15) Description of atmospheric (air quality) and biotic impacts are described above in Sections 5.14 and 5.9 respectively. 5.17.1 Hydrologic Information on water resources was obtained from a review of available data including the following: USGS, National Geospatial Program, USGS NED 1/3 arc -second Contours for Greeley E, and Sterling W, Colorado (USGS, 2018); • U.S. Fish & Wildlife Service (USFWS) National Wetlands Inventory (NWI) (USFWS, 2018a); • FEMA Floodplain Map Service (FEMA, 2018); Leeward Renewable Energy Development, LLC 5-71 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) • Colorado Data Sharing Network (CDSN) Regulation 85 Data Upload & Submittal Info (CDSN, 2018); • Colorado Division of Water Resources (CDWR) Colorado Decision Support Systems ([CDSS], 2018a) and Colorado Well Permits Database (2018b); • NRCS Web Soil Survey (NRCS, 2017); and • USGS Land Cover (2011 Edition, amended 2014), National Land Cover Database (NLCD) (USGS, 2014); • USGS National Hydrography Dataset (NHD) (USGS, 2016). 5.17.1.1 Surface Waters and Quality There are numerous intermittent unnamed drainages within the Project Area, which flow southeast across the Project Area joining the only named drainage, Sidney Draw. The intermittent drainages and Sidney Draw drain the northern flank of the Project Area to form a confluence with Lodgepole Creek near Sidney, Nebraska which ultimately joins the South Platte River. Other surface waters within the Project Area flow via unnamed intermittent drainages during snowmelt or precipitation events. There are no playas or designated livestock watering ponds within the Project Area. However, there are multiple, small intermittent ponds overlapping grassland and pasture/hayland which could be used for livestock watering. Further discussion on water resources can be found in Section 5.9.3 and discussion regarding wetlands and marshlands are presented in Section 5.9.4.1. Appendix A Figure 12 provides a map of water resources within the Project Area. The State of Colorado Water Quality Control Commission (WQCC) has adopted designated use classifications and numeric water quality standards for the state's streams, lakes, and reservoirs. The state's waterbodies are divided into segments to protect various uses. In Colorado there are five use classification groups: (1) agriculture; (2) aquatic life; (3) domestic water supply; (4) recreation; and (5) wetlands. Section 303(d) of the Clean Water Act (CWA) requires states to identify waters that are not attaining their designated use(s) and develop total maximum daily loads (TMDLs) which represent the maximum amount of a given pollutant that a waterbody can assimilate and still meet its designated use(s). There are no waters within the Project listed as Section 303(d) waters (CDSN, 2018). During Project construction, existing drainage patterns will be preserved. Permanent facilities for the Wind Energy Facility, including substations will be sited outside of stream channels. The Transmission Facilities will span all stream channels, drainages, and irrigation ditches. Should any new or improved access roads, cross stream channels be required, appropriately sized culverts will be installed to maintain channel flow and morphology and will be authorized by applicable permits, if any. It is anticipated Leeward Renewable Energy Development, LLC 5-72 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) impacts to surface waters will be minimal due to siting of facilities outside of the channels and waterways, however minor water quality impacts may occur during construction as a result of stormwater. Increased turbidity and localized sedimentation of stream and gravel pond bottoms may occur from the stormwater runoff. However, these impacts will be localized and temporary, and should not alter water quality conditions. Implementation of erosion and sediment control BMPs as outlined in the SWMP will minimize water quality impacts. A preliminary drainage report was prepared for the two proposed substations and is included as Appendix M. The U.S. Environmental Protection Agency (USEPA) sets requirements for oil spill prevention, response, and clean-up in Title 40 Code of Federal Regulations (CFR) Part 112, otherwise known as the Oil Pollution Act of 1990. Title 40 CFR Part 112 requires facility owners and operators to prepare an SPCC Plan if their facility meets criteria for potential impacts to waters of the U.S. and/or oil storage. Leeward will prepare a SPCC Plan as well as a Hazardous Materials Management Plan Framework that will cover the larger category of hazardous materials. 5.17.1.2 Ground Water Groundwater resources in the Project Area occur in two primary aquifer types: alluvial aquifers and sedimentary rock aquifers. Groundwater in the Project Area is contained within the High Plains or Ogallala sedimentary aquifer which underlies 112 million acres, or 175,000 square miles within eight states, including: Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming (USGS, 1995). The geologic deposits containing this aquifer were deposited around 10 million years ago and consist of gravel, sand, clay, and silt. The Project Area is not located within any named regional alluvial aquifer (CDWR, 2018a). Groundwater in alluvial aquifers often interact with surface water of the stream system. The Ogallala alluvial aquifer and unnamed aquifers occur along the majority of the Project Area. Groundwater levels can be expected to fluctuate, in response to annual and longer -term cycles of precipitation, irrigation, surface drainage, and the development of transient, perched water conditions. It is anticipated that groundwater levels will rise and fall, in general, with the stages of Sidney Draw in the Project Area. The CDWR well permit database was queried to determine number of drilled water well logs within the proposed Project Area (CDWR, 2018b). Those results are presented in Table 5-12 and shown on Appendix A Figure 4.

Sixteen water wells have been permitted within the Project Area in addition to a total of 44 constructed wells; 2 abandoned wells; 9 wells with permits which have expired; 6 wells with permits which were cancelled; 6 wells with unknown status; and a total of I I wells in which applications were either received, withdrawn, or application information was requested. Permitted wells in the Project Area consist of domestic stock, irrigation, and sampling/monitoring wells. Constructed wells in the Project Area are for domestic, stock, irrigation, industrial, and commercial uses. Based on the above well mapping data (CDWR, 2018b), the wind and transmission facilities will not impact known wells. Prior to construction, proposed areas for Project facilities and mapped well locations will be field verified. The Project will not impact hydrologic flow of groundwater and will not affect groundwater recharge. Water will be required to support Project construction, including road development, concrete production and foundations, dust control, and other construction activities. Water for construction will be purchased from a to -be determined off -site source and trucked onto the site by a licensed contractor. On -site water supplies will include the previously developed, existing O&M facility for the Project and no long-term use of water will be necessary for commercial operation of the Wind Energy Facility or the Transmission Leeward Renewable Energy Development, LLC 5-76 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Facilities. Leeward will comply with all local, state, and federal permitting requirements regarding development and use of on -site water sources for the Wind Energy Facility, if necessary, however, it is not anticipated. 5.17.1.3 Flood Hazard Area and Historical Flooding Activity Floodways include the channel of a river or other watercourse and adjacent areas. Floodways should be reserved to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height and not increase upstream flood elevations. Zone AE, A, AO, and AH floodplains are Special Flood Hazard Areas that will be inundated by a flood event having a 1 -percent chance of being equaled or exceeded in any given year. The 1 -percent annual chance of flood is also referred to as the base flood or 100 -year flood. Moderate flood hazard areas (Zone X areas) are located between the limits of the base flood and the 0.2 percent annual chance or 500 -year flood (FEMA, 2018). FEMA updated the floodplain mapping for Weld county as of January 20, 2016 and based on that information, there are no mapped FEMA floodplains (Weld County, 2018b) within the Project Area proposed for Project development. 5.17.2 Geologic The region is underlain by two major geological formations, the White River and the Ogallala formations. The White River formation is primarily located within the extreme western half of the Project Area, while most of the Project Area is on exposures of the Ogallala formation. The Brule Member of the White River formation consists of terrestrial sedimentary rocks (300 meters thick), including mudstones, siltstones, sandstones, minor conglomerates, and volcanic tuffs. The Neocene Ogallala formation contains many vertebrate fossils. See section 5.9.4.5 and Appendix 1 for a further discussion of the paleontological resources. The Project Area is within the Colorado Piedmont province of the Great Plains physiographic region (Colorado Geological Survey, 2018). The Great Plains physiographic region major landforms include valleys, lowlands, outwash plains, and alluvial fans and terraces. The Colorado Piedmont province consists of broad hilly valleys under 5,000 feet in elevation stretching north and northeast from Denver in the valley of the South Platte River. The geologic units mapped within the Project Area include COTo Sedimentary (Tertiary): Sandstone conglomerate and COTwr Sedimentary (Tertiary): Sandstone and claystone (Tweto, 1979). Two prominent geomorphologic features in the area are the Pawnee Buttes and the Chalk Bluffs which rise above the surrounding plains. The buttes are erosional remnants left standing as the surrounding High Leeward Renewable Energy Development, LLC 5-77 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Plains surface has gradually worn away. The lower portions of the buttes are composed of relatively soft, clay -rich sedimentary rock called the Brule formation. The Brule formation is protected by an overlying layer of sandstone and conglomerate sediments called the Arikaree formation, which are more resistant to weathering (Hazlett, 1998). The major topographical feature in the Project Area is the plateau upon which the proposed Wind Energy Facility will be located. The construction and operation of the Project will not alter the geology of the Project Area or opportunities for mineral collection. The topography of the Project Area is relatively flat to rolling and with elevations ranging from approximately 5,090 feet to 5,500 feet AMSL from the Project Area's eastern boundary to the northwest corner (USGS, 2018). The numerous intermittent unnamed drainages throughout the Project Area flow southeast and join the only named drainage present, Sidney Draw. All of these drainages form a confluence with Lodgepole Creek near Sidney, Nebraska which ultimately flows into the South Platte River. Wind turbines and Project facilities will primarily be located along relatively flat expanses of highlands. Steep slopes or escarpments will be avoided to the extent practicable. Prior to constructing the Project, Leeward will complete a geotechnical analysis of the Project Area. The design and construction of the Project will fully consider subsurface conditions and will not negatively impact any steeply sloping or unstable terrain. 5.17.3 Pedologic The soils within the Project Area primarily consist of loam to fine -sandy loam derived mostly from wind - reworked alluvium and/or calcareous sandy eolian deposits, and calcareous loamy alluvium. The soils in the Project Area are not highly susceptible to erosion and are generally conducive to crop production (NRCS, 2017). Based on soil pH, none of the soils within the Project Area are highly corrosive to buried steel (pH<5.5 or pH>8.5), or highly corrosive to concrete (pH<5.5). Soils in the Project Area are well drained and none of the soils have a significant hydric component (30 to 100 percent of the soil is hydric). Additionally, none of the soils are considered to have a high potential for frost action (NRCS, 2017). Table 5-13 lists the soil types comprising more than 1 percent of the Project Area and the characteristics of these soils. A map of these soil classifications is provided in Appendix A Figure 14.

Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity. Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. The soils in the Project Area are moderately susceptible to erosion and have K Factors ranging from 0. I to 0.43, with the majority between 0.24 and 0.43. Slopes in the Project Area range from 1 to 25 percent, with the majority of slopes at 1 to 10 percent. The Project will not adversely affect any soil types. Construction of the Project will cause some localized soil compaction and increase the potential for soil erosion. Long-term effects associated with soil compaction and erosion will be minimized or negated through implementation of Leeward's standard construction mitigation practices (Appendix G) and the following mitigation measures: • Movement of construction vehicles and equipment will be limited to the construction ROW, existing Weld County roads, and other access routes that may need to be negotiated with private landowners. • Following the completion of work, compacted soils will be loosened and graded by scarification, harrowing, disking, or other approved methods. • All disturbed areas will be re -graded and, where appropriate, re -seeded to provide proper drainage, stabilize soils, and prevent erosion. • Construction -phase sediment and erosion -control measures will be implemented where appropriate. Leeward Renewable Energy Development, LLC 5-82 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) 5.17.4 Visual During construction, the immediate viewshed of the Project Area will be temporarily impacted by construction activities, including vegetation removal, trench digging, materials stockpiling, and the presence of equipment. However, the Project will not deteriorate any existing viewsheds, unique landscapes, or other natural aesthetics. The landscape already has numerous wind turbines in operation from the existing Cedar Creek I Wind Farm and Cedar Creek II Wind Farm, therefore it is likely the visual impact of the Wind Energy Facility will be minor to sensitive occupants of local rural farms and homesteads. Furthermore, most of the area has been previously impacted by the conversion of native habitat to disturbed agricultural land. Visual simulations for the wind facilities are included in Appendix N. Visual impacts will be mitigated by adhering to Weld County setback requirements for wind turbines and transmission structures (please refer to section 5.6.10). To the extent possible, wind turbines and facilities will be sited in previously disturbed agricultural land to avoid impacting native habitat and reduce the visual impacts of the Project in the natural environment. Following construction, temporarily disturbed areas will be returned to preconstruction contours; the topsoil will be replaced; and all remaining disturbed areas will be re -seeded according to Weld County and/or landowner requirements to minimize the visual impacts in the area. 5.17.4.1 Shadow Flicker With respect to wind turbines, shadow flicker can be defined as an intermittent change in the intensity of light in a given area resulting from operation of the wind turbine due to its interaction with the sun. While indoors, an observer experiences repeated changes in the brightness of the room as shadows cast from the wind turbine blades briefly pass by windows as the blades rotate. For this to occur, the wind turbine must be operating; the sun must be shining; and the window must be within the shadow region of the wind turbine; otherwise, there is no shadow flicker. A stationary wind turbine only generates a stationary shadow similar to any other structure. Weld County zoning code does not provide a no exceedance requirement for shadow flicker resulting from wind turbines. Leeward will implement a voluntary commitment of limiting shadow flicker to 30 hours per year or less at participating and non -participating residences, unless a waiver is signed by the landowner granting permission to exceed the voluntary commitment. Leeward will take steps to mitigate shadow flicker concerns at residences that could experience shadow flicker concerns at residences that could experience shadow flicker levels above 30 hours per year. Mitigation measures such as vegetative screening, and awning, or darkening shades can be implemented to address shadow flicker concerns should they arise after the Project is operational. Leeward Renewable Energy Development, LLC 5-83 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Leeward completed a shadow flicker analysis for the existing turbine layout and those results are included in Appendix P of this application. 5.17.5 Noise The Project is located in rural Weld County, Colorado. Zoning in the Project Area is classified as Agricultural Zoning District. The Project Area contains cropland, grassland/herbaceous, pasture/hay, and rural residences scattered throughout. The landscape also has numerous wind turbines in operation from the existing Cedar Creek I Wind Farm and Cedar Creek II Wind Farm, therefore it is likely the noise impact of the Wind Energy Facilities will be minor to occupants of local rural farms and homesteads. The existing turbine operation, farming activities and vehicular traffic are assumed to be the largest contributor to sound. Sound level requirements for Wind Generators are outlined in Section 23-4-450(1)(1-4) of the Weld County Code and are as follows: WIND GENERATORS are subject to the following noise limits (measured from the nearest property line from the WIND GENERATOR): 1) Residential: Fifty (50) decibels; 2) Commercial: Fifty-five (55) decibels 3) Light industrial (I -I Industrial): Sixty-five (65) decibels; 4) Industrial (1-2 and 1-3 Industrial): Seventy five (75) decibels. Due to the Agricultural Zone of the Project Area there are no specific Wind Generator noise standards under the Weld County Code. Because of this, the County's residential limit (i.e., 50 A -weighted decibels — "dBA") was used as a design goal at the exterior of each occupied residence. Project components are likely to create noise during operation. Wind turbines create noise through aerodynamic processes (i.e., the blade passing through the air) and through mechanical (i.e., motors within the nacelle). The sound levels produced by wind turbines are not expected to significantly impact the surrounding areas, and levels are expected to be less than the County's residential limit at all occupied residences. Because the sound levels diminish with distance, the 3.1 times the tip height minimum distance from residences will reduce the noise levels emitted by the turbines as they propagate towards surrounding areas. Leeward Renewable Energy Development, LLC 5-84 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) A predictive noise modeling analysis was completed using the current turbine layout and vendor - provided, worst -case sound level inputs (see Appendix Q). Various assumptions were made in the model to produce conservative predictions. The modeling results indicate that the Project noise levels would not exceed the maximum permissible residential noise level at any occupied residence within the Project Area. The predictive noise modeling analysis shows that the current Mountain Breeze and Panorama Wind Energy Facility turbine layout will be compliant with Weld County Code requirements (WCC 14-9- 40) and State Statue (C.R.S. Sec. 25-12-103) for Noise. Based on these results, the Project is expected to generally have similar or lesser impacts than the nearby Cedar Creek II Wind Farm (USR-1723), which requires compliance with noise levels applicable to Industrial land uses as set forth in Section 14-9-30 of the Weld County Code. . Audible noise from overhead transmission lines is produced by a phenomenon known as corona. Corona is caused by the ionization of the air at the surface of the energized conductor and suspension hardware, due to very high electric -field strength. Corona is a function of voltage, the diameter of the conductor, and the condition of the conductor and suspension hardware. The electric field around an energized conductor is directly related to the line voltage and is the greatest at the surface. The proposed Transmission Facilities will use conductors of sufficient diameter to control corona effects. With overhead construction of transmission lines, standard conductor attachment hardware is typically adequate to control corona. Higher voltages require special low -corona hardware. Overhead transmission lines can create audible noise (AN) via voltage on the system as well as a phenomenon known as corona. AN due to voltage on the system typically have a very low amplitude. Corona noise is caused during wet -weather conditions, typically during foul weather. Both AN and corona noise are often masked by ambient sounds in an area. The background ambient noise level varies with wind, rain, traffic, or other human activity. Because of this, AN and corona noise are typically not a concern for wind farm transmission lines. The Project will also create temporary noise impacts as a result of construction activities, vehicles, and equipment in operation in the area. The construction noise impacts will be concentrated in areas of work and temporary in duration. 5.18 Surface and Subsurface Drainage (21-3-330.B.16) Erosion and sediment control drawings and details will be developed during the final design of the Project. Because the Project will disturb greater than 1 acre of land, construction will require coverage under a general permit for Stormwater Discharges Associated with Construction Activities (Stormwater Leeward Renewable Energy Development, LLC 5-85 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Areas and Activities of State Interest — Application Requirements (21-3-330) Construction Permit) issued by the CDPHE. A condition of the permit is the development and implementation of a SWMP. The SWMP will be developed during final design of the Project and will incorporate erosion and sediment control plans and details. In general, it is anticipated that erosion will be primarily controlled through: • Vehicle tracking control at access points; • Concrete washout areas; • Silt fence on the downgradient side of the work area; • Orange construction fence on the upgradient side of the work area; • Use of straw or rock waddles on steeply sloped or cross sloped installations; • Temporary stockpile stabilization areas; • Rock check dams along roadside ditches and draws; • Post -construction seeding and mulching; and • Post -construction establishment of wetland areas. The SWMP will include requirements for regular inspection and maintenance intervals for installed erosion controls. 5.19 Decommissioning Plan The design life of the Wind Energy Facility equipment (i.e., wind turbine generators, transformers, and interconnect) is a minimum of 20 years. However, if properly maintained, the life of the turbines can be extended beyond 20 years. To extend the life of the facility, wind energy equipment can often be re - powered and retrofitted with newer technology, such as newer, more efficient wind turbine generators. In the event that wind generation at the Project site is terminated, Leeward will decommission the facility by removing foundations to a depth of 4 feet below grade where feasible and requested by landowner, removing re -saleable or salvageable material, and disposing of all unsalvageable material at an authorized site. The soil surface will be restored as close as practicable to its original condition.

The Mountain Breeze project is in final negotiations of a Power Purchase Agreement (PPA) for the full output of the project which should be complete in Ql of 2019. The details of the PPA will be provided as additional supplemental information once available in Ql 2019. The Project will allow for new renewable energy resources in Weld County, Colorado and will continue for 25 years serving Colorado energy needs. Additionally, the Projects have received positive feedback from stakeholders and will provide employment opportunities, economic impacts including royalties to landowners, charitable donations, and support of the local community. The Projects proposed will help to supply the region's demand for additional renewable energy resources and will provide economic stimulus to the local community including the following: • Property tax payments will be made of an estimated $17 million over the life of the projects. • Approximately 120 construction jobs will be created for the wind facility and transmission line facilities. • An estimated 15 to 20 new long-term, full-time operational jobs will be created when the facility becomes operational. • Option and royalty payments will be paid to the approximately 40 families with turbines and ancillary facilities on their land. • Option and easement payments will be paid to the approximate 8 landowners for the transmission line facilities. • Increased demand for local materials and services will occur during both construction and commercial operations contributing to sales tax revenue. Leeward Renewable Energy Development, LLC 1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Appendix G - Construction Practices and Mitigation Measures CONSTRUCTION PRACTICES AND MITIGATION MEASURES The following measures will be implemented by, Leeward Renewable Energy Development, LLC (Leeward) for mitigating impacts from the proposed Mountain Breeze and Panorama Wind Energy Facility. I. Construction of the overhead transmission line will require minimal clearing of the chosen right- of-way. Reclamation of temporarily disturbed areas around the transmission structures, including roads not needed for maintenance, will be completed by regrading, disking, mulching, fertilizing, and reseeding with a native seed mixture appropriate to the type of vegetation disturbed and approved by the Natural Resources Conservation Service (NRCS) or as requested in writing by the landowner. Existing access will be used whenever feasible to minimize disturbance to vegetation resources. 2. In the entire Project Area, contractors will exercise care to preserve the natural landscape and will conduct construction operations to prevent any unnecessary destruction, scarring or defacing of the natural surroundings in the vicinity of the work. Except where clearing is required for permanent works, approved construction roads, or excavation operations, vegetation will be preserved and will be protected from damage by construction operations and equipment. 3. When construction is complete, all storage and construction materials and debris will be removed from the site. 4. All areas of potential soil disturbance within the Project Area will be surveyed for noxious weeds before construction begins. Noxious weeds will be managed in all surface disturbed areas. If herbicides are needed to control noxious weeds, they will be applied by a licensed contractor. Equipment will be washed at a commercial facility prior to construction and on -site during construction if weeds are found within or adjacent to the Project Area. A Leeward contractor will be responsible for monitoring, treating, and documenting noxious weeds throughout the life of the Project. A weed management plan similar to Cedar Creek I will be developed prior to construction. 5. Leeward will limit construction activities and equipment movement to access routes, the right-of- way or construction easement to minimize damage to residential yards. grazing land, crops, orchards, and property. Leeward will coordinate with landowners to avoid impacting the normal function of irrigation devices during Project construction and operation. 6. At the end of construction, Leeward will restore/rehabilitate all construction caused deep ruts that are hazardous to farming operations and to the movement of equipment. Such ruts will be leveled, Leeward Renewable Energy Development, LLC 1 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Appendix G - Construction Practices and Mitigation Measures filled and graded, or otherwise eliminated in an approved manner. Ruts, scars and compacted soils in hay meadow, alfalfa fields, pasture, and cultivated productive lands will have the soil loosened and leveled by scarifying, harrowing, discing, or other approved methods. Damage to ditches, tile drains, terraces, roads, and other features of the land will be corrected. At the end of each construction season and before final acceptance of the work in these agricultural areas, all ruts will be obliterated, and all trails and areas that are hard -packed as a result of construction operations will be loosened and leveled. The land and facilities will be restored as nearly as practicable to the original condition. 7. Standard mitigation practices will be required to avoid impacts to water resources. These will include those listed under the soil erosion plan and under a hazardous waste management plan to minimize the risk of contaminating water resources during Project construction. Construction activities will be performed by methods that prevent entrance or accidental spillage of solid matter, contaminants, debris, and other objectionable pollutants and wastes into flowing streams or dry water courses, lakes, and underground water sources. Such pollutants and wastes include, but are not restricted to refuse, garbage, cement, sanitary waste, industrial waste, oil and other petroleum products, aggregate processing tailings, mineral salts, and thermal pollution. 8. An erosion control/stormwater management plan will be developed and implemented to prevent sediment input to the drainages within the overall Project Area. The plan will be designed to meet the requirements of the Colorado Department of Public Health & Environment's (CDPHE) Construction Stormwater Discharge Permit. Measures associated with this plan will be implemented during Project construction and any future maintenance activities associated with the wind energy facility, transmission line, and switching station. Waste waters from construction operations will be handled in accordance with Corps of Engineers Nationwide Permit 12 and 51 and CDPHE Water Quality Control Division permit discharge requirements. Erosion mitigation measures will include the use of one or more devices such as temporary berms, slope drains, diversion mounds, or sedimentation basins, as appropriate. Silt fence will be used to prevent sediment from entering wetlands or open water. Temporary drainage control will also be implemented as appropriate to aid in controlling erosion and sedimentation. 9. Wetlands, floodplains rivers, streams, and lakes will be avoided whenever feasible. The location, alignment, and grade of construction roads will minimize impacts to wetland, riparian, and aquatic resources. Impacts to wetlands, including playa lakes at the wind energy facility site, are not expected to occur. 10. The proposed transmission line will cross one major drainage and numerous unnamed intermittent drainages, some of which drain into the South Platte River. Since the South Platte Leeward Renewable Energy Development, LLC 2 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Appendix G - Construction Practices and Mitigation Measures River is a jurisdictional "waters of the U.S." as designated by the Army Corps of Engineers and since some of these other drainages have the potential to be determined jurisdictional (by the Corps), consultation with this entity and notification of the Project will be required to avoid impacts or to implement appropriate mitigation. 11. Equipment and vehicles will avoid riparian areas on the right-of-way during construction and operation activities where possible and minimize impacts by using existing access points. Existing bridges or fords will be used to access the right-of-way on either side of riparian areas. 12. Leeward has identified and plans to conduct/has conducted a series of studies aimed at identifying existing wildlife resources on the wind farm site and along the transmission line corridor. These studies have been designed in consultation with CPW and USFWS. Studies that have been conducted or that will be conducted include: • Raptor Nest Surveys -Wind Energy Facility Site • Sharp -tailed Grouse Lek Surveys -Wind Energy Facility Site • Breeding Songbird Surveys -Wind Energy Facility Site • Mountain Plover Surveys -Wind Energy Facility Site • Sensitive Habitat Assessment -Wind Energy Facility Site and Transmission Line Route • Wetland Assessment -Wind Energy Facility Site and Transmission Line Route Upon completion of certain key preconstruction surveys identified above, Leeward will investigate and, to the extent necessary, propose a variety of potential site -specific and species - specific mitigation measures to mitigate potential impacts to wildlife. These measures may include actions such as: • Detailed transmission line preconstruction habitat assessment and raptor nest surveys; • Setbacks of either construction -related activities or permanent facilities (i.e. roads, towers) from sensitive areas; • Limiting time of construction to exclude breeding or nesting seasons; • Additional studies during construction and/or post operations to determine impacts; • Special design features aimed at minimizing avian impacts (i.e. perch deterrents, flight diverters. conductor spacing, etc); • Potential creation of habitat conservation areas to offset potential impacts; • Avoidance of impact to sensitive habitats and areas such as wetlands and black -tailed prairie dog colonies when feasible. Leeward Renewable Energy Development, LLC 3 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Appendix G - Construction Practices and Mitigation Measures Leeward will work cooperatively with CPW and USFWS to review potential impacts and select appropriate mitigation strategies given the nature of the proposed project, potential impacts, and likely effectiveness and feasibility of mitigation measures. 13. A cultural resource file search of the State Historic Preservation Office (SHPO) database has been conducted for the Project Area. In areas where sensitive historic, paleontological, or archeological resources are known to occur Leeward will design the layout of the Project infrastructure to avoid and minimize impacts to these resources. 14. Fire -fighting equipment will be located in vehicles and the O&M facility. Crew will coordinate with local fire -fighting personnel at the Cedar Creek I Fire Station and other facilities in the area. If fires cannot be extinguished with resources on -site, the landowner, sheriff, and local fire department will be advised. Fire deterrents within the wind farm will include access roads, which may serve as fire breaks and regular clearing of vegetation from areas around transformers, riser poles, and buildings. Annual reports detailing fire and fire suppression efforts will be recorded by O&M staff and provided to Leeward annually. 15. An Emergency Response Plan will be established for the Project to ensure employee safety for emergencies such as personnel injury, fires, explosions, and other scenarios where project evacuation will be required. The Emergency Response Plan will cover project employees, site visitors, and on -site contractors, and will be administered by the Project operations manager or designee. Part of this plan will include prior coordination with local emergency response agencies to plan for proper communication and response to on -site emergencies. Leeward Renewable Energy Development, LLC 4 Burns & McDonnell BURNS kMcDONNELL December 19, 2018 Weld County Department of Public Works 111 H Street Greeley, Colorado 80632 Re: Leeward Renewable Energy Development Expansion Project Weld County Sketch Plan Drainage Report To Whom It May Concern: This drainage letter demonstrates compliance with the Weld County Public Works Sketch Plan Drainage Report Outline, provided as Attachment 1, for two proposed substation platforms in Weld County. Leeward Renewable Energy Development, LLC (Leeward) plans to build two new substations, Panorama Substation and Mountain Breeze Substation, as part of their expansion efforts to increase the capacity of the Mountain Breeze Wind Energy Facility and the Panorama Wind Energy Facility. The proposed drainage improvements comply with the Weld County Chapter 23, Article XII and the Urban Drainage and Flood Control District's Urban Storm Drainage Criteria Manual (USDCM) requirements. Location Panorama Substation The new Panorama Substation site is located in the northeast and northwest 1/4 of Section 5, Tl 1N, R59W and consists of a parcel of land that is approximately 3.5 acres. Specifically, the Panorama Substation is located along County Road 134, approximately a half mile west of the intersection of County Road 134 and County Road 125. The proposed location is within unincorporated Weld County along the boundary of property owned by Rudy L Wohlgemuth. The adjacent property to the north is owned by Anton P Joska. There are no major open channels, lakes, streams, irrigation or other water resource facilities within or adjacent to the proposed project site. There is an unnamed drainage which flows intermittently southeast of the location. Mountain Breeze Substation The new Mountain Breeze Substation is located in the NE 1/4 of Section 5, T1 1N, R58W and consists of a parcel of rangeland that is approximately 3.5 acres. Specifically, the Mountain Breeze Substation is located approximately a half mile east of the intersection between County Road 134 and County Road 111 along County Road 134. The proposed location is within unincorporated Weld County on property owned by Noel's Grasslands Ranch LLC to the north, Phillip Jason Smith to the west and O&M Harms LLC to the east and south. There are no major open channels, lakes, streams irrigation or other water resource facilities within or adjacent to the proposed project site. 9785 Maroon Circle \ Suite 400 \ Centennial, CO 80112 0 303-721-9292 \ F 303-721-0563 \ burnsmcd.com BURNS 4McDONNELL Weld County Department of Public Works December 19, 2018 Page 2 Location of each property is shown on Figure 1 provided in Attachment 2. Description of Property Panorama Substation The United States Geological Survey (USGS) was used to obtain 10 -foot contours for the site and surrounding area and was used as a basis of analysis for the project. The site soil consists of a clay loam soil which is classified as hydrologic soil group (HSG) C according to the Natural Resource Conservation Service (NRCS). The soil map created using the Web Soil Survey by the NRCS is provided in Attachment 3. The substation location and surrounding area is native, undeveloped land with scattered vegetation used as pasture. Existing topography slopes from north to south at approximately 3%. There are no existing on -site or adjacent drainage facilities. No groundwater characterization has been accomplished to date. Mountain Breeze Substation The United States Geological Survey (USGS) was used to obtain 10 -foot contours of the site and used as a basis of analysis for the project. The site soil consists of a sandy clay loam soil which is classified as HSG B according to the NRCS. The soil map created using the Web Soil Survey by the NRCS is provided in Attachment 3. The substation location and surrounding area is native, undeveloped land with scattered vegetation used as pasture. Existing topography slopes from west to east at approximately at 1%. There are no existing on -site or adjacent drainage facilities. No groundwater characterization has been accomplished to date. Major Basin Description Based on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Map No. 08123C0500E for Weld County, Colorado, Effective Date January 20, 2016, the project sites are located within Zone D. Zone D is an area of undetermined flood hazard. The flood hazard map is provided in Attachment 4. Offsite drainage around the Panorama Substation will have little impact on the substation property. The general direction of flow for runoff is south toward a native swale through the existing field, however most offsite flow north of the substation will be captured by the roadside ditches of County Road 134. Any offsite flow that hits the Panorama substation will be conveyed around the substation. Figure 2 in Attachment 2 presents the offsite drainage patterns around the Panorama Substation. The Mountain Breeze Substation will be impacted by offsite flow from the west, which flows toward a native swale east of the substation property. The gently sloping topography should not produce significant runoff. Any runoff impacting the site will be captured and conveyed around the site. Offsite drainage patterns impacting the Mountain Breeze Substation is shown on Figure 3 in Attachment 2. BURNS k1SDONNELL Weld County Department of Public Works December 19, 2018 Page 3 General Proposed Concept To accommodate the new substation facilities, proposed additions to the sites include new gravel surfacing, concrete foundations, electrical equipment, new chain -link security fencing and gates, and a new access drive. Minimal disturbance and construction methods will be utilized to complete the improvements. The disturbance will maintain the existing topography by clearing and grubbing, excavation, and replacing to existing grade. Minor grading will be completed to install foundations for new equipment. The limits of disturbance will be maintained with sediment control logs, fence and construction fencing for the duration of the improvements. In addition, a concrete washout structure will be utilized through the duration for all concrete activities. When the improvements have been completed, the final stabilization will be installed, including aggregate surfacing on the yard and roadways and seeding and mulching on all other disturbed areas. Specific Detail Panorama Substation The Panorama Substation will convey all offsite flow around the substation and outlet the flow to maintain the natural flow of water. The existing basin for the site consists of 3.5 acres of agricultural land with a C -value for the 10 -year storm event of 0.07 and a peak discharge of 0.6 cubic feet per second (cfs). The C -value for the 100 -year event is 0.44 and generates a runoff of 5.9 cfs. Proposed improvements at the Panorama Substation do not increase the contributing drainage area but do increase the imperviousness of the site. The addition of gravel surfacing is assumed to cover the entire substation with minimal areas of concrete for equipment foundations. The proposed condition C -values for the 10 -year and 100 -year events are 0.38 and 0.61, respectively. The resulting runoff is 4.4 cfs during the I 0 -year event and 12.5 cfs for the 100 -year event. Rational method calculations for the Panorama Substation are included in Attachment 5 and the runoff rates are shown on Figure 2 in Attachment 2. Mountain Breeze Substation The Mountain Breeze Substation will convey all offsite flow around the substation and outlet the flow to maintain the natural flow of water. The existing basin for the site consists of 3.5 acres of agricultural land with a C -value for the 10 -year storm event of 0.07 and a peak discharge of 0.6 cubic feet per second (cfs). The C -value for the 100 -year event is 0.44 and generates a runoff of 5.9 cfs.

The addition of gravel surfacing is assumed to cover the entire substation with minimal areas of concrete for equipment foundations. The proposed condition C -values for the 10 -year and 100 -year events are 0.38 and 0.61, respectively.

Rational method calculations for the Mountain Breeze Substation are included in Attachment 5 and the runoff rates are shown on Figure 2 in Attachment 2. Conclusion In review of the proposed improvements to the Panorama and Mountain Breeze Substations, the development was found to be compliant with the Municipal Code for Weld County Chapter 23, Article NI and the Urban Drainage and Flood Control District's Urban Storm Drainage Criteria Manual (USDCM) requirements. The development of the Panorama and Mountain Breeze Substations is dependent on the approval of the Mountain Breeze Use by Special Review (USR) Application. Upon approval of the application, design and calculations will be completed for each substation in accordance with USDCM. I hereby certify that this report for the preliminary drainage design of the Mountain Breeze Wind Energy Facility and the Panorama Wind Energy Facility was prepared by me (or under my direct supervision) in accordance with the provisions of the Weld County storm drainage criteria for the owners thereof.

Leeward Renewable Energy Development LLC TOC-4 Burns & McDonnell Sound Study Revision 0 Executive Summary 1.0 EXECUTIVE SUMMARY Leeward Renewable Energy Development, LLC (Developer) is proposing to construct the Mountain Breeze and Panorama Wind Energy Facility (Project). Burns & McDonnell Engineering Company, Inc. (Burns & McDonnell) was retained by the Developer to conduct a sound study for the Project. The proposed Project will be located in Weld County, Colorado, while receptors for the project are located in Weld County (CO), Laramie County (WY) and Kimball County (NE). The Project is approximately 56 miles northeast of the city of Fort Collins and approximately 93 miles northeast of the city of Denver. The Project will include a quantity of 129 General Electric (GE) 2.82-127 wind turbine generators (WTG). The GE 2.82-127 WTG has a hub height of 89 meters and an aggregate nameplate capacity of approximately 2.82 megawatts. For purposes of this Study, a total of 133 turbine positions were evaluated (129 turbines to be built plus four potential alternates), although only up to 129 turbines are expected to be installed. The four alternate turbines were also modeled as the GE 2.82-127 turbine model. There were several objectives in this study, which included: • Identification of applicable county, city, State, or Federal noise ordinances; • Estimation of the operational sound levels from the Project layout using the three-dimensional sound modeling program Computer Aided Noise Abatement (CadnaA); and • Determination of whether the wind farm can operate in compliance with the identified applicable regulatory standards. There are no Federal noise regulations that apply to this Project. Therefore, only local regulations apply. The State of Colorado and Weld County provide sound level limits based on zoning classification. While the State has noise rules, Weld County is a Home -rule county. As such, their noise regulation will be the guiding regulation. The Weld County Noise Ordinance states that noise produced by a source shall not exceed 55 A -weighted decibels (dBA) during daytime hours and 50 dBA during nighttime hours on residentially -zoned properties. Since the Project will be located on leased land from multiple property owners, that are all zoned for agricultural use, there are no overriding limits. Therefore, a design goal of 50-dBA at occupied residential structures was chosen. The wind turbines were modeled using manufacturer -specified sound power levels. Sound pressure levels were predicted at all identified receivers within and surrounding the Project area. There are no expected exceedances of the established design criteria due to operation of any of the Project wind turbine locations. Leeward Renewable Energy Development LLC 1-1 Burns & McDonnell Sound Study Revision 0 Acoustical Terminology 2.0 ACOUSTICAL TERMINOLOGY The term "sound level" is often used to describe two different sound characteristics: sound power and sound pressure. Every source that produces sound has a sound power level. The sound power level is the acoustical energy emitted by a sound source and is an absolute number that is not affected by the surrounding environment. The acoustical energy produced by a source propagates through media as pressure fluctuations. These pressure fluctuations, also called sound pressure, are what human ears hear and microphones measure. Sound is physically characterized by amplitude and frequency. The amplitude of sound is measured in decibels as the logarithmic ratio of a sound pressure to a reference sound pressure (20 microPascals). The reference sound pressure corresponds to the typical threshold of human hearing. To the average listener, a 3 -decibel (dB) change in a continuous broadband sound is generally considered "just barely perceptible"; a 5 -dB change is generally considered "clearly noticeable"; and a 10 -dB change is generally considered a doubling (or halving, if the sound is decreasing) of the apparent loudness. Sound waves can occur at many different wavelengths, also known as the frequency. Frequency is measured in hertz (Hz) and is the number of wave cycles per second that occur. The typical human ear can hear frequencies ranging from approximately 20 to 20,000 Hz. Normally, the human ear is most sensitive to sounds in the middle frequencies (1,000 to 8,000 Hz) and is less sensitive to sounds in the lower and higher frequencies. As such, the A -weighting scale was developed to simulate the frequency response of the human ear to sounds at typical environmental levels. The A -weighting scale emphasizes sounds in the middle frequencies and de-emphasizes sounds in the low and high frequencies. Any sound level to which the A -weighting scale has been applied is expressed in A -weighted decibels, or dBA. For reference, the A -weighted sound pressure level and subjective loudness associated with some common sound sources are listed in Table 2-1.

David Egan, 1988 and Architectural Graphic Standards, Ramsey and Sleeper, 1994. a) dBA = A -weighted decibels; mph = miles per hour Leeward Renewable Energy Development LLC 2-2 Burns & McDonnell Sound Study Revision 0 Regulations 3.0 REGULATIONS Federal, State, and county regulations were reviewed to determine the applicable overall sound level limits for the Project. The Noise Control Act of 1972 (The Act) (United States Code [U.S.C.1 4901) mandated a national policy "to promote an environment for all Americans free from noise that jeopardizes their health or welfare, to establish a means for effective coordination of Federal research activities in noise control, to authorize the establishment of Federal noise emission standards for products distributed in commerce, and to provide information to the public respecting the noise emission and noise reduction characteristics of such products." As required by The Act, the U.S. Environmental Protection Agency (EPA) established criteria for protecting the public health and wellbeing. However, these criteria do not constitute enforceable Federal regulations or standards. The EPA has since delegated regulatory authority to local entities. Therefore, there are no Federal noise regulations that apply to this Project. The State of Colorado provides sound level limits based on zoning classification (Colorado Noise Statute Section 25-12-103 — Maximum Permissible Noise Levels). However, Weld County is a Home -rule county. As such, their noise regulation takes precedence as the guiding regulation. The Weld County Code of Ordinances Section 14-9-40 — Maximum Permissible Noise Levels provides sound level limits for various types of zoned properties. The Project will be located on leased land from multiple property owners that are all zoned for agricultural use. There are no limits for agriculturally -zoned properties. The Weld County Noise Ordinance states that noise produced by a source shall not exceed 55 dBA during daytime hours and 50 dBA during nighttime hours on residentially -zoned properties. Therefore, the residential nighttime sound level limit (i.e., 50 dBA) was chosen as a design goal for the exterior of any occupied residence. Leeward Renewable Energy Development LLC 3-1 Burns & McDonnell Sound Study Revision 0 Wind Turbine Sound Modeling 4.0 WIND TURBINE SOUND MODELING The sound commonly associated with a wind turbine is described as a rhythmic "whoosh" caused by aerodynamic processes. This sound is created as air flow interacts with the surface of rotor blades. As air flows over the rotor blade, turbulent eddies form in the surface boundary layer and wake of the blade. These eddies are where most of the "whooshing" sound is formed. Additional sound is generated from vortex shedding produced by the tip of the rotor blade. Air flowing past the rotor tip creates alternating low-pressure vortices on the downstream side of the tip, causing sound generation to occur. Older wind turbines, built with rotors which operate downwind of the tower (downwind turbines), often have higher aerodynamic impulse sound levels. This is caused by the interaction between the aerodynamic lift created on the rotor blades and the turbulent wake vortices produced by the tower. Modern wind turbine rotors are mostly built to operate upwind of the tower (upwind turbines). Upwind wind turbines are not impacted by wake vortices generated by the tower and, therefore, overall sound levels can be as much as 10 dBA less than downwind wind turbines. The rhythmic fluctuations of the overall sound level are less perceivable the farther one gets from the turbine. Additionally, multiple turbines operating at the same time will create the whooshing sound at different times. These non -synchronized sounds will blend together to create a more constant sound to an observer at most distances from the turbines. Another phenomenon that reduces perceivable sound from turbines is the wind itself. Higher wind speed produces self -generated sound that tends to mask (or drown out) the sounds created by wind turbines. Advancement in wind turbine technology has reduced pure tonal emissions of modern wind turbines. Manufacturers have reduced distinct tonal sounds by reshaping turbine blades and adjusting the angle at which air contacts the blade. Pitching technology allows the angle of the blade to adjust when the maximum rotational speed is achieved, which allows the turbine to maintain a constant rotational velocity. Therefore, sound emission levels remain constant as the velocity remains the same. Wind turbines can create sound in other ways as well. Wind turbines have a nacelle where the mechanical portions of the turbine are housed. The current generation of wind turbines uses multiple techniques to reduce the sound from this portion of the turbine: vibration isolating mounts, special gears, and acoustic insulation. In general, all moving parts and the housing of the current generation wind turbines have been designed to minimize the sound generated. Leeward Renewable Energy Development LLC 4-1 Burns & McDonnell Sound Study Revision 0 Wind Turbine Sound Modeling 4.1 Model Inputs and Settings Predicted sound levels were modeled using industry -accepted sound modeling software. The program used to model the turbines was CadnaA, Version 2019, published by DataKustik, Ltd., Munich, Germany. The CadnaA program is a scaled, three-dimensional program that accounts for air absorption, terrain, ground absorption, and ground reflection for each piece of sound -emitting equipment and predicts downwind sound pressure levels. The model calculates sound propagation based on International Organization for Standardization (ISO) 9613-2:1996, General Method of Calculation. ISO 9613, and therefore CadnaA, assesses the sound pressure levels based on the Octave Band Center Frequency range from 31.5 to 8,000 Hz. Compliance with the regulations for all turbines operating should equate to compliance for any combination of turbines operating. 4.1.1 Project Layout The Project layout contains 133 total wind turbine sites. Predictive modeling was conducted to determine the impacts at the residential structures surrounding the Project. The turbine locations are shown in the turbine layout figure included as Figure A-1 of Appendix A. There are 47 residences near the Project. 4.1.2 Terrain and Vegetation Terrain and attenuation from ground absorption can have a significant impact on sound transmission. U.S. Geological Survey (USGS) Digital Elevation Model (DEM) contours were imported into the model to account for topographic variations around the Project. The terrain around the Project is mostly rural with few minor changes in elevation. Vegetation is mostly low-lying with some small areas of trees. Therefore, vegetation was excluded from the analysis to maintain conservativeness in the model. Ground attenuation is expected to be fairly high, due to the "soft ground" of the surrounding areas; however, a conservative value of 0.5 was used in the model. 4.1.3 Sound Propagation and Directivity CadnaA calculates downwind sound propagation using ISO 9613 standards, which use omnidirectional downwind sound propagation and worst -case directivity factors. In other words, the model assumes that each turbine propagates its maximum sound level in all directions at all times. While this may seem to over -predict upwind sound levels, this approach has been validated by field measurements. Under most normal circumstances, wind turbine sound is not significantly directional, but tends to radiate uniformly in all directions. Leeward Renewable Energy Development LLC 4-2 Burns & McDonnell Sound Study Revision 0 Wind Turbine Sound Modeling 4.1.4 Atmospheric Conditions Atmospheric conditions were based on program defaults. Layers in the atmosphere often form where temperature increases with height (temperature inversions). Sound waves can reflect off the temperature inversion layer and return to the surface of the earth. This process can increase sound levels at the surface, especially if the height of the inversion begins near the surface of the earth. Temperature inversions tend to occur mainly at night when winds are light or calm, usually when wind turbines are not operating. CadnaA calculates the downwind sound in a manner which is favorable for propagation (worst -case scenario) by assuming a well -developed moderate ground -based temperature inversion (such as those that can occur at night). Therefore, predicted sound level results tend to be higher than what would actually occur. The atmosphere does not flow smoothly and tends to have swirls and eddies, also known as turbulence. Turbulence is basically formed by two processes: thermal turbulence and mechanical turbulence. Thermal turbulence is caused by the interaction of heated air rapidly rising from the heated earth's surface, with cooler air descending from the atmosphere. Mechanical turbulence is caused as moving air interacts with objects such as trees, buildings, and wind turbines. Turbulent eddies generated by wind turbines and other objects can cause sound waves to scatter, which in turn, provides sound attenuation between the wind turbine and the receiver. The acoustical model assumes laminar air flow, which minimizes sound attenuation that would occur in a realistic inhomogeneous atmosphere. This assumption also causes the predicted sound levels to be higher than what would actually occur. 4.1.5 Sound Emission Data Acoustical modeling was conducted for the Project. Wind turbine heights and acoustical emissions were input into the model. The expected worst -case overall sound power levels for the turbines were contained in documents provided by the Developer from the respective vendor Siemens Gamesa (SG), based on various wind speeds. The sound emissions data supplied was developed using the International Electrotechnical Commission (IEC) 61400-11 acoustic measurement standards. The expected sound power level and modeled heights for the turbine type to be installed are displayed in Table 4-1. The total sound power level for the GE 2.82-127 is 110.0 dBA.

Leeward Renewable Energy Development LLC 4-3 Burns & McDonnell Sound Study Revision 0 Wind Turbine Sound Modeling A point source at the hub was used to model sound emissions from the wind turbines. This approach is appropriate for simulating wind turbine sound emissions due to the large distances between the turbines and the receivers as compared to the dimensions of the wind turbines. The corresponding sound levels from the table above were applied to every point source. Locations of receivers and wind turbines around the Project area were provided by the Developer and the turbine layout is shown in Figure A-1 of Appendix A. Each receiver was assumed to have a height of 1.52 meters (5.0 feet) above ground level. Compliance with the regulation was assessed at the residential structure (each receiver). The following assumptions were made to maintain the inherent conservativeness of the model and to estimate the worst case modeled sound levels: • Attenuation was not included for sound propagation through wooded areas, existing barriers, and shielding • All turbines were assumed to be operating at maximum power output (and therefore, maximum sound levels) at all times to represent worst -case noise impacts from the wind farm as a whole 4.2 Acoustical Modeling Results Sound pressure levels were predicted for the identified receivers in the CadnaA noise modeling software using the manufacturer -specified sound power levels and the assumptions listed above. CadnaA modeling results have been demonstrated in previous studies to conservatively approximate real -life measured sound from a source when extraneous sounds are not present. As previously mentioned, decibels are a logarithmic ratio of a sound pressure to a reference sound pressure. Therefore, the decibels must be logarithmically added to determine a cumulative impact (i.e., logarithmically adding 50-dBA and 50-dBA results in 53-dBA). Logarithmically adding each of the individual turbine's impacts together at each receiver provides an overall Project impact at each receiver. There are no expected exceedances of 50 dBA at the identified residences. Appendix A shows the turbine layout and residences in the Project Area. The sound level modeled at each residential structure for the Project is provided in Appendix B. Leeward Renewable Energy Development LLC 4-4 Burns & McDonnell Sound Study Revision 0 Conclusion 5.0 CONCLUSION Burns & McDonnell conducted a predictive sound assessment study for the Project. The study included identification of applicable sound regulations and predictive modeling to estimate Project -related sound levels in the surrounding community. Sound pressure levels were predicted at occupied receivers within and surrounding the Project area using manufacturer -specified sound power levels for each wind turbine. A number of conservative assumptions were applied to provide worst -case predicted sound pressure levels. Those results were then compared to the identified design goal. There are no expected exceedances of the 50-dBA design goal due to operation of any of the Project wind turbine locations.

The available GLO plat maps indicate that the area was originally surveyed in 1871. 1873, and 1875, with no structures of historic value depicted. The original land patents for the Project area indicate that much of the area was patented under the Original Homestead Act (12 Stat. 392), land grants given to the Union Pacific railroad (12 Stat 489), and the Colorado Enabling Act (18 Stat. 474). Several of the Original Homestead patents were acquired by the Federal government under the Bankhead-Jones Farm Tenant act of 1937 (50 Stat. 522) (BLM 2018b). A file search conducted in the NRHP and SR HP data bases indicate that there are no sites listed on either of the registers within the Project area (NPS 2018; OAHP 2018b). There are no Centennial Farms located within the Project area (OAHP 2018c). A review of US Geological Survey (USGS) (1997a; 1997b; 1997c; 1997d; 1997e) maps of the area indicate that a single cemetery, the Higday (Sunnyside) Cemetery, is located at the southwest corner of the intersection of roads 119 and 134 (USGS 1997a). The cemetery contains 11 graves markers that date between 1911 and 1928, with additional unmarked graves (Coloradogravestones 2018).

The region is underlain by two major geological formations, the White River and the Ogallala. The White River formation is primarily located within the southwestern portion of the Project area, while most of the area is on exposures of the Ogallala formation. The Brule Member of the White River formation consists of terrestrial sedimentary rocks (300 -meters - thick), including mudstones, siltstones, sandstones, minor conglomerates, and volcanic tuffs. The paleoenvironment was an aggregational meandering river system with the conglomerates and sandstones reflecting the stream channels and fine-grained clastic rocks (mudstones and siltstones) deposited during periodic overbank flooding by the river. It is the sandstone layers that are fossiliferous. The Ogallala formation consists of an apron of clastic sediments that were shed eastward from the uplifting Rocky Mountains during the Laramide Orogeny (ca. 65 million years ago). This included in a succession are sediments such as lacustrine marls, tuffs, and intraclastic conglomerates. The Neocene Ogallala formation is richly fossiliferous with extinct early forms of dogs, cats, pigs and horses, as well are mollusks, plant seeds, and petrified wood. While the formation is fossiliferous, it is much less than the Brule member of the White River formation. Studies conducted to the northeast (Nebraska) and to the south of the Project area, suggest that vertebrate finds could be very common within the local badlands and drainage slopes. The vertebrate fossils from the Brule Member include specimens of reptiles (snakes, lizards, tortoises and turtles), fish (catfish and sunfish), and mammals (ancestral modern lineages: horses, dogs, cats, mustelids, camels, deer, rhinoceros, rodents, rabbits, insectivores, and marsupials and extinct lineages: brontotheres, entelodonts, oreodonts, hyaenodonts, sabertooth cats), and terrorbirds. These include partial finds and well -articulated skeletons of many of the larger mammals. This is due to a combination of paleoecology (a burrowing community) and unique preservation conditions (secondary calcite cementation) combined with increased acidic erasion (Sundell, K, 1997; Sundell, C., 1998). Leeward Renewable Energy Development, LLC 5 Burns & McDonnell Mountain Breeze and Panorama Wind Energy Facility Cultural Resource Desktop Study Paleontological Recommendations The potential of paleontological finds within the Project area should be considered high for three primary reasons: I) the Brute Member of the White River formation has been known to contain a high occurrence of paleontological resources, however it varies in occurrence and predictability; 2) the Ogallala formation has been known to contain occurrences of paleontological resources, however it greatly varies in occurrence and predictability; 3) surface disturbing activities may adversely affect paleontological resources. The probability for impacting significant paleontological resources is moderate to high and is dependent on the proposed action. Mitigation plans must consider the nature of the proposed disturbance, such as the removal or penetration of protective surface alluvium or soils, potential future accelerated erosion, or increased ease of access that could result in looting. Detailed field assessment is normally required but would be determined if it is necessary by the Arapaho and Roosevelt National Forest and the Pawnee National Grasslands as the reviewing agency.

Throughout the permitting process, the Project will also complete a detailed decommissioning plan which will be designed by a reputable engineering company with experience completing such plans. This decommissioning plan may be dependent upon ongoing permitting processes; thus, it may need to be completed as a condition of approval of the permit. Any shortfall in adequate financial assurance will be identified by such a decommissioning plan and the Project will work to put in place a financial structure that will be agreed to in conjunction with Weld County prior to construction being initiated. Leeward Renewable Energy Development, LLC 1 Burns & McDonnell GE Renewable Energy GE's IviW Platform PROVEN, RELIABLE WIND ENERGY SOLUTIONS YESTERDAY, TODAY, AND TOMORROW. www.gerenew leenergy.com GE'S 2 MW PLATFORM 1 Since entering the wind industry in 2002, GE Renewable Energy has invested more than $2.5 billion in next -generation wind turbine technology to provide more value to customers —whether turbine, • or grid level.

With - integration of big data analytics and the industrial• customers manage the variability• onshore product portfolio includes wind turbines with rated capacities from 2.0 to 4.8 MW and flexible support services that range from basic operations and maintenance to farm resource for smooth, predictable power. Our For more information visit our website: 2 MW Platform GE's 2 MW Platform of onshore wind turbines has more than 5.5 GW installed and operating today. Building on that success, GE offers a 127 -meter rotor option for 2.2-2.5 MW rated wind turbines. Featuring the best -in -class capacity factor and a significant improvement in Annual Energy Production (AEP) within the 2 MW range, the 2 MW -127 demonstrates the next step in turbine technology and efficiency, reducing the cost of energy for customers with low and medium wind speed sites. GE's 2.0-2.5 MW, 116 -meter rotor wind turbine offers 10,660 square meters in swept area, with an Annual Energy Production (AEP) of 11,832 MWh at 8.0 m/s (at a 2.5 rating, 90m HH). GE's proprietary 56.9 -meter blade is designed specifically for the 2.0-2.5 MW rating of this platform, enabling lower loads and improved performance. GE's stringent design practices enable a platform of products engineered for exceptional performance and availability. The use of selected components from proven product platforms ensures consistent workhorse performance and reliability. The 2 MW Platform drivetrain and electrical system architecture provide improved performance along with greater wind turbine energy production. Other critical components have been scaled from the existing platforms to meet the specific technical requirements of this evolutionary turbine. Today, GE's 2 MW Platform wind turbines come equipped and ready to utilize GE's Predix core applications, including its Asset Performance Management (APM), Cybersecurity, and Business Optimization (BO) solutions. The digital suite of apps enables improved business outcomes, including lifecycle extension of the customers' windfarms and the improvement of overall farm economics. GE's 2 MW Platform of onshore wind turbines set the benchmark for consistent performance, reliability, farm level AEP, and efficiency. Comparative statements refer to GE technology unless otherwise stated. 3 GE'S 2 MW PLATFORM Building Upon Proven GE Technology The evolution of GE's 2 MW Platform began with the introduction of a 1.5 MW turbine (the 1.5i) with a 65 -meter rotor in 1996. That product evolved to a 70.5 -meter rotor turbine, called the 1.5s. A 77 -meter rotor machine called the 1.5s1e was introduced later in 2004. Building on the exceptional performance and reliability of the 1.5s1e, GE introduced the 1.5x1e, wnich had a 82.5 -meter rotor, in 2005. Subsequent improvements led to the introduction of the 1.6-82.5 turbine in 2008 —followed by the 1.6-87 in 2011, and ultimately the 1.85-82.5 and 1.85-87 in 2013. Ongoing investment in the industry workhorse resulted in 100 -meter rotor machines with the introduction of GE's 1.6-100 and 1.7-100 wind turbines. Evolving from these predecessors, the GE 2 MW Platform of onshore wind turbines today provide even greater capacity factor while also increasing the AEP of GE's product offerings. Significant component enhancements have resulted in a substantial performance increase, enabling the use of the 116 and 127 -meter rotors, and a nameplate range of 2.0-2.5 MW (with applicable rotor). New aerodynamics and blade structural enhancements have enabled greater blade lengths, which, in conjunction with an upgraded electrical system, improved controls, and improved power conversion capabilities, have enabled increases in nameplate, capacity factor, and AEP. Made for high reliability, and with more than 5.5 GW of equivalent units installed and operating today, GE's 2 MW Platform has a proven record of providing excellent availability for our customers. 4 Technical Description GE's 2 MW Platform is a three -blade, upwind, horizontal axis wind turbine with a rotor diameter of either 116 or 127 -meters.

Leeward Renewable Energy Development, LLC TOC-5 Burns & McDonnell Shadow Flicker Analysis Revision 0 Introduction 1.0 INTRODUCTION 1.1 Study Overview Burns & McDonnell Engineering Company, Inc. ("Burns & McDonnell") was retained by Leeward Renewable Energy Development, LLC (the "Developer") to conduct a shadow flicker analysis (the "Study") for the proposed Mountain Breeze and Panorama Wind Energy Facilities (collectively, the "Project"). The objective of the Study was to estimate the annual frequency of shadow flicker on occupied residences caused by Project wind turbines. No attempt was made in this Study to examine or opine on health effects related to shadow flicker. 1.2 Project Overview The proposed Mountain Breeze and Panorama Wind Energy Facility will be located in Weld County, Colorado, while receptors for the project are located in Weld County (CO), Laramie County (WY) and Kimball County (NE). The Project is located approximately 56 miles northeast of the city of Fort Collins and approximately 93 miles northeast of the city of Denver. The Project will include a quantity of 133 GE 2.82-127 wind turbine generators. This turbine model has a hub height of 89 meters and an aggregate nameplate capacity of approximately 2.82 megawatts ("MW"). A map showing the general location and configuration of the Project Site is included in Appendix A. For purposes of this Study, a total of 133 turbine positions were evaluated (including 4 alternates), although only up to 129 turbines are expected to be installed. All turbines, including alternates, were modeled as the GE 2.82-127 turbine model. 1.3 Shadow Flicker Overview Shadow flicker occurs when wind turbine blades pass in front of the sun to create recurring shadows on an object. Such shadows occur only under very specific conditions, including sun position, wind direction, time of day, and other similar factors. The intensity of shadow flicker varies significantly with distance, and as separation between a turbine and receptor increases, shadow flicker intensity correspondingly diminishes. Shadow flicker intensity for distances greater than 10 rotor diameters is generally low and considered imperceptible. At such distances, shadow flicker most commonly occurs at sunrise or sunset, when cast shadows are sufficiently long. Shadow flicker impacts are not currently regulated in applicable state or federal law, nor are there requirements in the current Weld County (CO) ordinance with regard to limitations on shadow flicker Leeward Renewable Energy Development, LLC 1-1 Burns & McDonnell Shadow Flicker Analysis Revision 0 Introduction durations. This report identifies those receptors that may experience shadow flicker more than 30 hours per year, although it is noted that this threshold is presented as a typical industry benchmark for similar studies and not as a suggested limitation. 1.4 Site Visit Burns & McDonnell did not visit the Project Site as part of this Study. The contents of this evaluation are based exclusively upon desktop analysis by Burns & McDonnell. Leeward Renewable Energy Development, LLC 1-2 Burns & McDonnell Shadow Flicker Analysis Revision 0 Modeling Parameters and Inputs 2.0 MODELING PARAMETERS AND INPUTS 2.1 Modeling Overview Shadow flicker was modeled at the Project Site using WindPRO, an industry -leading software package for the design and planning of wind energy projects. This package models the sun's path with respect to every turbine location during every minute over a complete year. Any shadow flicker caused by each turbine is then aggregated for each receptor for the entire year. The following sections are summaries of the inputs utilized in the WindPRO model for this Study. 2.2 Turbine Coordinates Shadow flicker intensity is partially dependent upon the distance from a receptor to the turbine causing the shadow. The Developer -provided coordinates of each turbine are presented in Appendix A and the location of each turbine is presented graphically in Appendix D. For purposes of this Study, a total of 133 turbine positions were evaluated (including 4 alternates), although only up to 129 turbines are expected to be installed. 2.3 Turbine Dimensions The size of a wind turbine, including both hub height and rotor diameter, contributes to the length and width of the shadows that may be cast by that turbine. The Project will include up to 129 wind turbines when constructed. Table 2-1 presents the turbine models that were modeled as part of this Study and their respective dimensions. Table 2-1: Turbine Model Dimensions Turbine Model . Hub Height Im] Rotor Diameter Im] GE 2.82-127 89 127 2.4 Receptors A quantity of 47 receptors were modeled at the Project Site. The Developer -provided coordinates of each receptor are presented in Appendix C and the location of each receptor is presented graphically in Appendix D. Burns & McDonnell did not provide an independent verification of the location or occupied status of these receptors. Each receptor was modeled in "green house" mode within the WindPRO model. This approach provides a conservative estimate of the amount of time when shadow flicker could occur by modeling each receptor Leeward Renewable Energy Development, LLC 2-1 Burns & McDonnell Shadow Flicker Analysis Revision 0 Modeling Parameters and Inputs as having windows on all sides and effectively causing the home to be susceptible to flicker effects in all directions. 2.5 Terrain The WindPRO model utilizes topography data to place turbines and receptors at the proper elevations. This information is also used by the model to consider any natural land features between a turbine and a receptor that may block shadows from being seen at a receptor. Publicly -available terrain data was downloaded from the National Elevation Dataset, a product of the United States Geological Survey. The 10 -meter resolution digital elevation model DEM was exported at 10 -foot intervals for use in the WindPRO model. Elevations were assigned by Burns & McDonnell to each turbine and each receptor using this data. 2.6 Obstacles Obstacles located between a receptor and a turbine, such as trees or buildings, may significantly reduce or eliminate the duration and/or intensity of shadow flicker. However, as Burns & McDonnell did not visit the Project Site as part of this Study and could not make in -person observations regarding the size or influence of obstacles, no attempt was made to model the presence of potential obstacles. This approach also provides the most conservative estimate of the amount of time when shadow flicker could occur. 2.7 Turbine Operation Shadow flicker is contingent upon the movement of the turbine blades. Shadow flicker can only occur when the turbine is in operation (i.e., when the turbine blades are rotating). Moreover, shadow flicker is generally most notable when a turbine is facing a receptor, as this results in the widest -possible shadow being cast. To more accurately reflect the periods of operation of each Project wind turbine, on -site hub - height wind data was provided by the Developer and used to indicate the periods when the turbines are inactive due to wind speeds below the turbine cut -in speed or above the turbine cut-out speed, at which time the turbine rotor is not in motion and no shadow flicker will occur. Project Site -specific wind data was also utilized to model the actual orientation of the turbines relative to each receptor. The Developer -provided wind data includes data collected by an on -site meteorological mast, as shown in Appendix B. Power curves for the proposed turbines were provided by the Developer. These power curves were added to the WindPRO model to more accurately reflect the turbine's operational characteristics. The Developer -provided power curves are shown in Appendix B. Leeward Renewable Energy Development, LLC 2-2 Burns & McDonnell Shadow Flicker Analysis Revision 0 Modeling Parameters and Inputs 2.8 Flicker Relevance At distances beyond 10 rotor diameters, shadow flicker effects are generally considered low, as shadows diffuse and become imperceptible. Thus, a distance equal to 10 times the rotor diameter of each turbine (i.e., 1270 meters) was modeled as the maximum distance at which shadow flicker was considered relevant; receptors greater than this distance from a given turbine were not evaluated. The proximity of this buffer relative to each receptor is presented graphically in Appendix D. 2.9 Sun Angle The sun's path with respect to each turbine location is calculated by the WindPRO model to determine the cast shadow paths during every minute over a complete year. However, at very low sun angles, the light must pass through more atmosphere and becomes too diffused to form a coherent shadow. Thus, a value of three .(3) degrees was utilized for the height at which the sun would not cause noticeable flicker. 2.10 Environment Shadow flicker is only caused when the sun is shining. Sunshine probability data was obtained by Burns & McDonnell from www.city-data.com, as shown in Appendix B. This data represents the percentage of hours each month that the sun is expected to be shining during daylight hours, with consideration given for cloud cover, rainy days, fog, or other similar occurrences that may diminish the potential occurrence or severity of shadow flicker. Leeward Renewable Energy Development, LLC 2-3 Burns & McDonnell • Shadow Flicker Analysis Revision 0 Results 3.0 RESULTS Using the inputs and parameters defined in Section 2.0, the WindPRO model was used to calculate shadow flicker for the receptors at the Project Site. Table 3-I presents a summary of these results, while detailed tables are included within Appendix C that present shadow flicker durations by receptor, including estimated hours per year. Additionally, maps are provided in Appendix D which illustrate the shadow flicker vectors (in hours per year) caused by each Project turbine. Table 3-1: Summary of Results Turbine Layout No. of Turbines No. of Receptors No. of Receptors, Flicker > 30 hr/yr No. of Receptors, Flicker = 0 hr/yr 133 x GE 2.82-127 133 47 6 34 The following is a set of key observations from the results of the Study: • With the current layout, 6 of 47 known receptors exceed 30 hours per year of shadow flicker. Refer to Appendix C for a complete listing of results. • The majority of observed shadow flicker on each receptor occurs during early morning and/or late afternoon and evening hours, as shown in Appendix E. • -For purposes of this Study, a total of 133 turbine positions were evaluated, although Burns & McDonnell understands that only up to 129 turbines are expected to be installed. Depending on the turbine location(s) that are eliminated, flicker durations at impacted receptors are likely to decrease from those presented herein. • The Study was performed using a conservative modeling approach with Project Site -specific conditions. For example, the Study modeled each receptor as a "green house", meaning each receptor was modeled as having windows on all sides and effectively causing the home to be susceptible to flicker effects in all directions. Further, the Project Site was modeled as if no obstacles were present, including trees or buildings, which may significantly reduce or eliminate the duration and/or intensity of shadow flicker at a receptor. Due to the conservative approach of the Study, the actual duration and intensity of shadow flicker experienced at each receptor is expected to be less than those reported in the Study. • Notwithstanding any shadow flicker which may occur at the Project Site, mitigation techniques may be utilized to reduce these effects. Common techniques include planting vegetation, awning installation, and/or reduced turbine operation.
