(BEI) will provide dust abatement for the proposed Wind Farm project. A water truck and dust palliative (Calcium Chloride) will be used to treat the on-site areas (haul roads, access roads, aggregate processing areas, etc) in order to suppress dust. A water truck and dust palliative will be used to control dust in circulation areas and material handling/stockpile areas. Construction vehicle speeds will be reduced on graveled county roads to 45 mph, speeds will also be reduced to 25 mph on all project access road going into the Wind Farm to aid dust suppression. On a daily basis prior to starting up project operations all haul roads, stock pile areas, and circulation areas will be inspected to determine if wetting the surfaces are needed. If the roads and stockpiles are dry where dust could be generated they will be wetted using a water truck. • The same areas will be inspected throughout the day to determine if wetting the areas is needed. If at any time during the day the project begins to generate dust that is leaving the site, BEI will have the water truck on stand-by such that an area can be wetted as soon as possible.

Introduction Blattner Energy, Inc. is committed to work within the parameters of all federal, state and local environmental protection policies and regulations at all project locations. This long -standing commitment includes activities that take place at our corporate office and any other office location. We also require any subcontractor, vendor and any other applicable or effected entity to conform to our `standard of commitment' while they are associated with our operations. In the event of a conflict within the coordination of requirements of applicable promulgated standards, the stricter of those laws will be applied and enforced. Dust can affect the health of people, property or business. Dust can also represent a risk to safety when conditions are allowed to inhibit visibility. Operators of a construction site must take reasonable precautions to prevent dust from becoming airborne and from being tracked onto paved public roads. 1.a. Responsible Personnel Craig Arneson, (320) 761-0201 Brandon Kraus, (320) 260-0950 • Dust Abatement Plan, 2010 Blattner Energy, Inc. • 1.b. Sources of Dust Construction sites generate dust from a variety of sources. These sources include: • Vehicle and equipment traffic on unpaved roads • Wind erosion from disturbed and exposed soils • Materials handling Please refer to section 2 for recommended Best Management Practices (BMP) for each of these sources. 2. Recommended Best Management Practices Dust abatement procedures are a significant concern on Blattner Energy, Inc. projects. Blattner Energy, Inc. incorporates a variety of abatement procedures as conditions dictate. Abatement techniques include preventing the creation of fugitive dust, binding dust particles together, and reducing wind speed at ground level. Dust abatement efforts shall be monitored and recorded during the stormwater inspection conducted on a weekly basis and after rain events. 3.a. Water • During the duration of the project, Blattner Energy, Inc. will have two 4,000-gallon water trucks in operation. This will be the primary method of dust control. Additional water trucks will be employed during the peak summer season when evaporations rates are highest. Water trucks will operate the full length of the shift(s) so that fugitive dust emissions do not interfere with safety or neighboring property lines. Blattner Energy, Inc. will apply water so that the surface is visibly moist on trafficked roads and in the areas where work is taking place. 3.b. Chemical Dust Suppressant Blattner Energy, Inc. recognizes that extreme conditions may require additional dust control methods. Blattner Energy Inc. may employ the use of a Colorado State approved dust palliative applied using the admix method and/or to the surface of gravel access roads at the application rate and frequency specified by the manufacturer. Dust palliative will be applied 100' in each direction of a public road intersection and 1/4 mile in each direction of a private driveway and public road. 3.c. Stabilization Blattner Energy, Inc. will take preventative measures to limit dust from disturbed • soils. Disturbed surface areas will be controlled via construction sequencing and clearing will be kept to a minimum width within the right ways. Topsoil will be Blattner Energy, Inc.

(BPWENA) Bridgette Miranda, BPWENA Project File As part of the draft conditions of approval of the Cedar Creek II Wind Farm Project(USR-1723), Cedar Creek II, LLC is required to provide written evidence of compliance with the U.S. Army Corps of Engineers (USACE), Section 404 of the Clean Water Act Permit. Tetra Tech wetland scientists, working on behalf of Cedar Creek II, LLC, completed a delineation of waters of the United States, including wetlands and playa lakes in the Project area. A total of 26 ephemeral drainages, 26 playa lakes, and 7 wetlands were delineated. Cedar Creek II, LLC used these • data to design the Project in a manner that avoided potential waters of the U.S. to the maximum extent practicable. One exception was a playa lake that is bisected by Weld County Road 126 (CR 126), one of the proposed haul routes for Project construction. Cedar Creek II, LLC will comply with USACE requirements to conduct road improvements along CR 126. Cedar Creek II, LLC is currently working with the USACE Denver Regulatory Office to obtain a preliminary jurisdictional determination for this playa lake. If the USAGE determines this feature is not a"jurisdictional water of the U.S."then no permit under the Clean Water Act will be necessary. If the USACE determines that the playa site is a jurisdictional water of the U.S., the USACE has tentatively recommended that the project apply for a Nationwide 14 Permit. A Nationwide Permit 14 is written for linear transportation projects that result in fill to waters of the U.S. As a backup plan, the Project may change the haul route to avoid this playa lake altogether. Tetra Tech submitted a request for a preliminary jurisdictional determination to the USACE Denver Regulatory Office on May 12, 2010. Cedar Creek II, LLC will supply Weld County with the response from the USAGE as soon as it is received. Per conversation with you and David Bauer on May 10, 2010, a copy of this correspondence with the USACE will satisfy the condition of approval to provide written evidence of compliance with the USACE. • Tel Fax SGS bp BP Wind Energy S David Gonzalez BP Wind Energy North America Inc. 700 Louisiana, 33'°Floor Houston,TX 77002 Direct 713-354-2138 Direct Fax:713-354-2120 Email: david.gonzalez2@bp.com May 14,2010 Chris Gathman Weld counts ?lar;ung Depattmenl Weld County Planning Department GREELEY OFFICE 1555 N. 17th Avenue zu�O Greeley, CO 80631h� Re: USR-1723 Decommissioning Plan RECEIVED a\/ ED Dear Chris, As we discussed via conference call on March 23,2010, this letter contains the Cedar Creek II,LLC decommissioning plan. • • Upon termination of this Land Lease and Wind Easement or decommissioning of the Wind Facilities located on the Premises, Lessee(Cedar Creek II,LLC) shall bear all costs and expenses to remove all of the Wind Turbines,roads, substations, transmission lines,and met towers from property. • All wind facilities will be removed within 240 days of termination of the Land Lease and Wind Easement. • All wind facilities will be removed to a depth of 4 feet below the surface of the ground. • All non-salvageable waste material will be disposed in an environmentally sound manner in a landfill that is legally approved to accept waste of this volume and characterization. • Lessee will use reasonable commercial efforts to restore the land to its original condition.

Phase One will occur during facility construction. Phase Two will be applied following completion of construction activities as an on-going effort during the active life of the project. Each phase will incorporate appropriate management objectives and control strategies. Integrated weed management (IWM) will serve as the foundation for all management actions associated with this project. Phase One: Weed Management During Facility Construction During this phase of the project, weed management will focus on prevention of weed spread and introduction of new weed populations. Weed prevention is addressed by: • limiting opportunities for weed propagules (e.g. seeds, shoots, root fragments) to enter an area or move between areas; • reducing negative human impacts to existing vegetation; • maintaining healthy and vigorous plant communities that can exclude weeds, should they enter the local system. Site workers will be briefed with descriptions of weeds common to the area primarily those on the Weld County "B" noxious weed list during their first day orientation. Observations of any populations in facility construction areas will be recorded and communicated to a project location database. In order to prevent spread of seed or other propagules, in areas where noxious weeds do occur, care will be taken on a daily basis to inspect, remove, and dispose of noxious weeds and propagules found attached to vehicles prior to leaving that particular site. All construction site vehicles/ heavy equipment will be washed prior entering the jobsite for the first time to prevent spread of Noxious weeds. This and any other removed weed material will be collected in large, durable plastic bags and disposed of in a manner and at a location approved by the Weld County Weed Coordinator. Several sources have noted the thick cover of a healthy, strongly competing native plant community can be an important component of weed control. Management practices that minimize disturbance to native plant communities reduce opportunities for weeds to invade the site. This includes careful use of off-road vehicles and limiting soil disturbances in natural vegetation areas whenever possible. 411 Blattner Energy,Inc. Blattner Energy, Inc Weed Mgmt Plan, 2010 Confidential Document Page 2 of 5 Noxious Weed Mgmt Plan, 2010 Blattner Energy, Inc • Careful revegetation of surface disturbed areas will also help prevent new weed infestations by using certified weed-free fill, topsoil, seeds, mulch, and vigorous native plant materials. A seed mix of native grasses found to grow well in the vicinity of the Cedar Creek II site will be developed for revegetation of disturbed areas. Construction activities for the Cedar Creek II Wind Farm will be conducted in a manner that supports the goal of preventing new weed infestations. The following Best Management Practices (BMPs) will be employed during construction. • Other than vehicles essential to construction activities, no motorized vehicles will be allowed within construction zones and corridors. • Soil from areas identified as supporting noxious weed populations will not be introduced to the construction site, to avoid transport of weed seeds or other propagules. • Before construction activities commence within areas of noxious weeds, weed plants will be chemically treated by a state licensed contractor or cut/mown and the materials removed and disposed of before plants set seed to prevent release of weed seed. • • All seed, top soil, and mulch materials imported onto the Cedar Creek II site will be certified as weed-free. • All excavations, placement of fill soil, or other areas of surface disturbance will be revegetated with the site seed mix surface in order to facilitate establishment of desirable vegetation and discourage weed infestation. All revegetation seeding will incorporate the project revegetation plan, BMPs, and seed mixes. • Revegetation and weed treatment— Construction disturbance may require weed treatment over the summer and revegetation in the fall when there is sufficient moisture to ensure success. The results of the disturbance should be monitored to determine what noxious weed species are appearing, and whether a seeding will be necessary or whether natural revegetation is sufficient to out-compete weed species. Only native species should be used in re-vegetating disturbances; exotic species such as crested wheat, yellow sweetclover, alfalfa, or smooth brome should be strictly forbidden. A seed mix including species such as blue grama, buffalo grass, western wheatgrass, sideoats grama, sand dropseed, needle and thread grass, Indian rice grass, and little bluestem would be appropriate, as long as percentages of the species are appropriate (i.e. not too much sideoat grama that might completely dominate the mix). All • noxious weeds that appear within 200 yards of the wind turbines and maintenance roads should be monitored and reported to Blattner Energy. Blattner Energy, Inc. Blattner Energy,Inc Weed Mgmt Plan,2010 Confidential Document Page 3 of 5 Noxious Weed Mgmt Plan, 2010 Blattner Energy, Inc Post-Construction Weed Management • Post-construction weed management objectives will be eradiction of incipient weed populations, suppression of existing populations, and restoration of temporarily disturbed existing plant communities. Monitoring known weed populations and checking for new introductions will be done on a regular schedule throughout post-construction growing seasons. Monitoring efforts will concentrate on those weed species listed on the Weld County "A", "B", and "C" noxious weed lists. IWM control techniques appropriate to individual species and specific sites will be developed and employed in consultation with the Weld County Weed Division. These will include mechanical and chemical weed control. Revegetation techniques and BMPs discussed above will be implemented during this phase of project weed management as well. • • Blattner Energy, Inc Blattner Energy, Inc Weed Mgmt Plan,2010 Confidential Document Page 4 of 5 elTETRA TECH ! . .

General Location and Description This Final Drainage Report was prepared in support of the 1041 Use by Special Review Permit application (USR 1723)for the proposed Cedar Creek II (CCII)Wind Energy Facility and 230-kilovolt(kV) Transmission Line Project(Project). This Final Drainage Report and the associated drawings were prepared by a registered professional engineer licensed to practice in the state of Colorado. This Final Drainage Report addresses stormwater management for the proposed Project site development(Project Site). The proposed development includes an Operations and Maintenance (O&M) Building area, Substation area, and temporary facilities required only for construction including a Batch Plant, construction parking, office trailers, and material laydown areas. 1.1 Location 1.1.1 Township, Range, Section, %Section The Project Site will be located in the SW/4 SW/4 of Section 5, Township 11N, Range 57W, on privately owned land. For additional information regarding the Project location, refer to the cover sheet of the design drawings in Appendix C. 1.1.2 Local Streets • The Project is to be constructed within the northeastern quadrant of the intersection of County Roads (CR) 132 and CR 135. No other local streets are located within or adjacent to the Project Site. 1.1.3 Major Open Channels, Lakes, Streams, Irrigation, and Other Water Resource Facilities The Project Site is located at the upper edge (or headwater)of a large unnamed ephemeral drainage that flows to the north and then northwest off the site. The drainage passes under CR 135 through two 4-foot- diameter corrugated metal pipes approximately 2,000 feet north of the site. Refer to Appendix K for photographs depicting the culvert crossings. There are no other major open channels, lakes, streams, or other water resource facilities located near the Project Site. 1.1.4 Surrounding Developments The Project Site is located in unincorporated Weld County on agricultural land with no immediately surrounding developments,jurisdictions, towns, or municipalities. • Cedar Creek II Wind Farm Project 1-1 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 1.2 Description of Property • 1.2.1 Size of Project Area in Acres The overall Project Site is 20.15 acres in size. The Project Site has been divided into four major sub-areas as follows: 1 O&M Building Area 2.58 acres 2 Substation Area 2.92 acres 3 Concrete Batch Plant 3.50 acres 4 Construction Parking, Contractor Trailers, Materials Storage 8.00 acres Containers, and Laydown Areas Total 17.00 acres The remaining 3.15 acres of the Project Site are allocated for the installation of the proposed stormwater drainage channels and detention basin located on the northern side of the site. 1.2.2 Ground Cover and Soil Types The Project Site is located on agricultural land that is currently used for livestock grazing. The area can • be categorized as typical prairie, pasture, or rangeland in fair condition with approximately 50 to 75 percent ground cover(typically short grasses). This evaluation is based on the site visit performed by Tetra Tech in December 2009 (see site photographs in Appendix K). The soils types for the Project Site and surrounding/adjacent areas were obtained from the National Resources Conservation Service (NRCS)Web Soil Survey database (NRCS 2009)for the Project Site (dated April 30, 2009). The Project Site primarily consists of clay loams and sandy clay loams with slopes of 0.5 to 2 percent that grade from south to north across the site. The hydrologic soil group classification/ rating calculated by the NRCS database survey for the entire Project Site is Group B and the erosion factor K for the Project area ranges from 0.15 to 0.17, which indicates a low erosion potential for the soils. For additional information, refer to the soils reports from the NRCS database presented in Appendix I. Based on these ground cover and soil type characteristics, a curve number (CN) of 69 was used for the historical condition of the Project Site in the NRCS hydrologic modeling program Technical Release 55, WinTR-55, which is applicable for pastures, grasslands, or rangelands in fair hydrologic condition (NRCS 2003). A list of CN values and the respective cover type and hydrologic conditions for use in the WinTR-55 program are provided in Appendix J. • 1-2 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • 1.2.3 Major Open Channels and Ownership The Project Site is located at the headwaters of a large unnamed ephemeral drainage that flows to the north and then northwest off the site (see Section 1.1.3). No other major open channels are located on or adjacent to the Project Site. The land for the Project Site is currently owned by Gary Lavern Sheffler and Jean Marie Sheffler. The Shefflers also own the adjacent property located on the western side of CR 135. The property located southwest of the site and intersection of CR 135/132 is owned by the Rolland W. Hoops and Charlotte M. Hoops Trust. The property located southeast of the intersection of CR 132/135 is owned by the United States of America and is managed by the U.S. Forest Service. 1.2.4 Project Description The Project Site will consist of both temporary and permanent facilities that are required for the construction and subsequent operation of the CCII Wind Energy Facility. In the Preliminary Drainage Report and associated drawings (Tetra Tech 2010), these facilities were grouped together into two distinct sub-sites of the overall Project Site. This was done so that the temporary facilities and associated drainage structures (including a second separate detention basin)could be sized appropriately and then removed upon completion of the initial 250.5-megawatt(MW)construction phase of the CCII Wind Energy Project. However, after submittal of the Preliminary Drainage Report, Mr. Sheller(landowner) requested to keep all of the stormwater drainage structures in place after completion of construction (discussion with Cedar Creek II, LLC Project Manager David Gonzalez on April 19, 2010), and the construction contractor • for the Project also provided modifications to the proposed layout of the facility areas. Therefore, the Project Site layout has been revised/reconfigured within the original footprint and will only require one detention basin; the gravel stockpile/storage area for maintenance and repair of Project roads has been moved out of the Project Site as described below. A description of the Project facilities is provided below. The permanent facilities (to be utilized during the operations phase of the Project)will include the following: • O&M Building (approximately 7,200 square feet [sf])with two small covered storage areas and 10 parking spaces • Electrical substation for transmission of the power generated and collected from the wind turbine facility • Stormwater collection channels (3-feet-deep, grass-lined/triangular-type—T1 and P2)located on the northern edge of the Project Site • Detention Basin P(with 10-inch polyvinyl chloride [PVC] outlet pipe with an 8-inch orifice plate at the discharge of the pipe) • One permanent driveway access point located on CR 132 for both the O&M Building and Electrical Substation areas The O&M Building and Substation areas will consist of a Colorado Department of Transportation (CDOT) Class 5 gravel surface (6-inch thickness)with gated access and permanent, full-perimeter fencing as shown on the design drawings in Appendix C. • Cedar Creek II Wind Farm Project 1-3 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 The temporary construction facilities/areas (to be removed after construction)will include the following: • Concrete Batch Plant—mixing equipment, water and cement storage, and small sand and gravel stockpiles • Parking for construction personnel and visitors (total of 284 spaces) • Contractor trailers • Material storage containers • Equipment laydown area • Two temporary driveway access points—one driveway access located on CR 132 for the Concrete Batch Plant and one driveway access located on CR 135 for the construction parking, trailers, and storage/laydown area. The temporary construction facilities will also consist of a CDOT Class 5 gravel surface (6-inch thickness) as shown on the design drawings in Appendix C. In addition to the Project Site facilities described above, three gravel storage/stockpile areas will be located throughout the entire CCII Wind Energy Project, as shown in the design drawings located in Appendix C. Each gravel storage area will consist of approximately 1,000 cubic yards (CY)of CDOT Class 6 aggregate-base coarse materials. These materials will be available for use in the repair and maintenance of the Project haul roads during the construction phase of the Project. Details regarding the existing site features (e.g., utilities, roads, ownership, etc.) and proposed site layout, lot sizes, existing and proposed grading, stormwater structures (channels, detention basins, etc.), and proposed development information/appurtenances are shown on the design drawings in Appendix C. 1.2.5 Irrigation Facilities There are no known irrigation facilities within 200 feet of Project Site property. 1.2.6 Groundwater Characteristics Groundwater in the Project Site is contained in the High Plains aquifer underlying 174,000 square miles in Colorado, Nebraska, Wyoming, Kansas, Oklahoma, Texas, and New Mexico. The proposed facilities will not affect the hydrologic flow of groundwater or affect groundwater recharge.

Drainage Basins and Sub-Basins 2.1 Major Basin Description 2.1.1 Applicable Weld County Master Drainage Plans According to Mr. Clayton Kimmi of the Weld County Department of Public Works on January 15, 2009, no applicable Weld County Master Drainage Plans have been developed for the Project Site. 2.1.2 Major Basin Drainage Characteristics The major basin area for the Project Site consists of eight upland areas (slopes range from 10 to 15 percent)that transition to gently sloped pasture land (slopes range from 0.5 to 3 percent) and then drain into the large ephemeral drainage located to the north of the proposed site. The Project Site is located in the pasture lands of the southern portion of the drainage basin at distances from the uplands ranging from 0.25 mile to 1 mile. The drainage basin is largely agricultural and rangeland and consists of similar soil types and ground cover conditions as described in Section 1.2.2 of this report. In general, most of the upland areas naturally drain to the large ephemeral drainage located north of the Project area without passing through the Project Site as described in Sections 1.1.3 and 1.2.3 of this report. A small volume of the stormwater runoff generated from the southern uplands, which does not naturally circumvent the site, passes through the Project Site. Section 2.2.2 presents a discussion of off-site drainage impacts to the Project Site. • 2.1.3 FEMA-Defined Floodplains and Floodways Upon viewing the Federal Emergency Management Agency(FEMA)floodplain index map for Weld County on the FEMA Map Service Center website (www.msc.fema.00v), it is apparent that there are six FEMA floodplain map areas that comprise the entire CC II Wind Energy Project Area. It is estimated that the Project Site is located within Map Number*080266 0125C or*080266 0150C. Each map number is denoted with an asterisk. At the bottom of the index map, there is a corresponding asterisk that states, "Panel Not Printed—Area in Zone D." Based on the definitions of FEMA Flood Zone Designations, the definition of Zone D is, "Areas with possible, but undetermined flood hazards. No flood hazard analysis has been conducted." Based upon subsequent discussions between Matt Smith (Tetra Tech)and a representative at the FEMA Map Service Center on May 3, 2010, it was confirmed that no FEMA analysis of flood hazards has been conducted for these areas and that these six maps (including the maps listed above)were not produced and are not available. See Appendix L for the FEMA Floodplain Index Map for Weld County, floodplain map for the Project area, and Zone D description. 2.1.4 On-Site Contours Topographic contours for both the existing (historical) and developed (proposed) condition have been provided for the Project Site at 2-foot vertical intervals. The Grading and Drainage Plan in Appendix C presents additional details regarding the contours and developed grading of the Project Site. • Cedar Creek II Wind Farm Project 2-1 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 2.2 Sub-Basin Description • Z2.1 Historical Drainage Patterns The Project Site consists of gentle grades that slope from the south to the north at approximately 0.5 to 2 percent and connect to the headwater of the ephemeral drainage located north of the site. The historical on-site drainage pattern for the Project Site, therefore, is the conveyance of stormwater runoff from the south to the north across the site to the headwaters of the existing ephemeral drainage located north of/ adjacent to the Project Site. 2.2.2 Off-Site Drainage Flow Patterns The Project Site is bordered by CR 135 to the west, CR 132 to the south, and an unnamed ephemeral drainage to the north. The unnamed ephemeral drainage passes under CR 135 through two 4-foot-diameter corrugated metal pipes approximately 2,000 feet north of the site. For photos of the culvert crossings, refer to Appendix K. To the east of the Project Site is an abandoned borrow pit (previously used for mining of gravel)and then further east, a low-lying pasture land that slopes gently from south to north at a slope of approximately 0.5 percent. From the south, off-site stormwater runoff is generated by the northern side of CR 132 (because of the existing crown of the road)and is conveyed through the Project Site to the drainage north of the site. Off-site runoff generated from the uplands directly south of CR 132 is conveyed east along the southern side of CR 132, which acts as a berm (centerline elevation of road elevation increases from east to west)to prevent off-site runoff from entering the Project Site, and is then conveyed across CR 132 east of the Project Site and northward to the existing pasture land located east of the site. For additional details regarding evaluation of the CR 132 road berm, see the explanation at the end of this section. A majority of the off-site runoff from the southwest and west of the Project Site is conveyed to either the existing drainage located northwest of the Project Site (approximately 400 feet west of CR 135)or along the southern side of CR 132 as previously described. A portion of this off-site runoff is conveyed northeast across the intersection of CR 132 and CR 135 and onto the Project Site. In addition, runoff generated from the eastern half of CR 135 (because of the crown of the road) along the western and northwestern portion of the site also enters and is conveyed across the Project Site. To the east, a small amount of off-site runoff is conveyed across the northeastern portion of the Project Site and then into the headwater of the northern drainage. Overall, the off-site drainage runoff that flows through the Project Site is relatively small (total of approximately 3.85 acres). These off-site flows have been accounted for in the design of the Project Site grading and drainage channels to provide for safe conveyance of the off-site flows through the Project Site. The design also routes the off-site flows through the emergency spillway of the proposed detention basin. The developed drainage areas (DAs)for the Project Site, including delineation of the off-site areas that drain across the site, are shown in the design drawing in Appendix C. As requested by Mr. Kimmi in his comments on the Preliminary Drainage Report(dated February 10, 2010), Tetra Tech performed a hydrologic analysis to evaluate the volume of the runoff generated from south of CR 132 in order to demonstrate that the 100-year stormwater runoff flow would not overtop CR 132 and drain across the Project Site. 2-2 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • The following is a summary of the procedure used to perform this evaluation: 1. Identify the lowest elevation for potential overtopping of CR 132 that would cause off-site runoff to flow across the Project Site. The lowest elevation along the crown of CR 132, which borders the developed condition DAs for the Project Site, was determined to be 5,140.67 feet mean sea level (msl). 2. Delineate the 5,140.67-foot contour along the southern side of CR 132. This elevation acts as the crest of the storage area that is bound by CR 132 to the north and upland slope to the south. The surface area for this contour was calculated to be 1.67 acres. 3. Delineate the lowest contour within the storage area, which is the bottom elevation of the existing drainage channel located adjacent/south of CR 132 (channel has very slight bottom slope of 0.01 percent and drains from west to east). A contour elevation of 5,140 feet msl was identified, which serves as the bottom elevation of the storage area. The surface area for this contour was calculated to be 0.72 acres. 4. Delineate the DA south of CR 132 that contributes runoff to the potential road crossing area. The size of the CR 132 South DA was calculated to be 151.94 acres of existing grasslands. 5. Identify the effective weir length for the outlet of storage area. At the intersection of the storage area and CR 132 DA to the east, the bottom width of the 5,140-foot contour elevation was determined to be 20 feet and the top width of the 5,140.67-foot contour at the intersection of the contour to the south was determined to be 125 feet. Therefore, it was estimated that the equivalent weir length is the average of these two lengths or 72.5 feet. 6. Perform WinTR-55 modeling of the 100-year stormwater event runoff for the CR 132 DA. The runoff • flow rate calculated for the DA is 59.46 cubic feet per second (cfs) (see Section 3.2.3 for additional details regarding WinTR-55 runoff modeling procedure). 7. Route the 100-year storm hydrograph through the effective storage area and weir outlet. The calculated peak flow rate through the effective weir outlet is 58.90 cfs, with a maximum depth stage (or depth of flow)of 0.41 feet above the bottom elevation, and a storage volume of 0.44 acre-feet (see Section 3.2.4 for additional details regarding WinTR-55 routing procedure). 8. Compare the calculated depth of flow through the weir (elevation of 5,140.41 ft msl)and the lowest elevation along the crown of CR 132 (elevation of 5,140.67 ft msl). 9. Conclusion: The top elevation of the flow based on calculated depth along the southern side of CR 132 (through the effective weir) is 5,140.41 feet msl, which is approximately 3 inches less than the CR 132 crown elevation of 5,140.67 feet msl. Based on this evaluation, it was determined that the 100-year flow from the DA south of CR 132 does not overtop the road and drain across the Project Site. Therefore, the proposed stormwater drainage structures designed for the Project Site do not need to include this runoff from this DA. Refer to Table 1 for the calculation of the time of concentration (Tc), Table 5 for a summary of the weir flow parameters, Appendix A for the WinTR-55 hydrology modeling output, Appendix B for the hydraulic calculations, and Appendix C for the CR 132 Drainage Area Map. • Cedar Creek II Wind Farm Project 2-3 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • 3. Drainage Design Criteria The criteria developed for the design of the stormwater management system for the Project Site are based on the guidance provided in Volumes 1, 2, and 3 of the 2008 Urban Storm Drainage Criteria Manual(USDCM) published by the Urban Drainage and Flood Control District (UD&FCD)and the 2006 Weld County Urban Storm Drainage Criteria Addendum to the USDCM (Weld County Addendum). 3.1 Development Criteria Reference and Constraints 3.1.1 Previous Drainage Studies No previous drainage studies (i.e., project Master Drainage Plans)for the Project Site have been prepared that would influence or be influenced by the proposed drainage design for the site. 3.1.2 Site Constraints Existing constraints (e.g., drainages, slopes, streets, utilities, existing structures, irrigation ditches, etc.) for the Project Site are considered minimal. An existing overhead electrical distribution line runs parallel to CR 135 and approximately 100 feet inside the western boundary of the site; however, the site plan facilities and structures have been arranged so that no impacts from the overhead lines will occur. 3.2 Hydrological Criteria • 3.2.1 Design Rainfall The design storm depth information was obtained from the National Oceanic and Atmospheric Administration (NOAA)Atlas 2, Volume III, Figures 26 through 31 (NOAA 1973). NOAA Atlas figures that depict the Project Site location are provided in Appendix G. 3.2.2 Design Storm Recurrence The design storm recurrence intervals used for the historical and developed site conditions for the Project are the 2-, 5-, and 100-year events with 24-hour storm durations, respectively.The rainfall depths for each of these design storm events are shown in Table 7. In addition, this table also provides the 2- and 100-year depths for the 1-, 2-, and 6-hour storm durations, respectively. Since the Project Site is located outside of the rainfall data/curves provided in the USDCM (Volume 1, Chapter 4—Rainfall), the 1-hour depths were calculated using the equations for Region 1 provided in NOAA Atlas 2 figures (see Appendix G), which use both the 6-and 24-hour storm values as shown in the table. The 1-hour storm values were then used to calculate the 2-hour storm depth values based on the conversion factors provided in Table RA-2 from Volume 1, Chapter 4—Rainfall (see Appendix H). These calculated 1-and 2-hour storm depths have been provided for reference purposes since these values are input parameters for the design storm calculation procedure provided in the USDCM. It should be noted that each of the 1-and 2-hour depth values range from 0.75 to 1.28 inches less than the corresponding 24-hour duration depths. • Cedar Creek II Wind Farm Project 3-1 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 3.2.3 Runoff Calculation Methods and Models The historical and developed condition runoff calculations for the Project Site were performed using WinTR-55 hydrologic modeling program and the standard unit hydrograph method. The WinTR-55 program was used to calculate the stormwater hydrographs with corresponding runoff flow rates and volumes for the delineated DAs (T1, T2, P1, and P2)for the 5-year/24-hour and 100-year/24-hour storm events associated with both the historical and developed drainage conditions for the Project Site. These hydrographs and output data were then used to size the project drainage channels, detention basin and outlet structure/pipe (see Section 3.2.4), and erosion controls. The following are the model inputs required for the WinTR-55 Program: • Land Use Details—Input for each individual project DA including cover description, hydrologic soil group, curve number, and corresponding surface area • Time of Concentration (TO—Time required for water to travel along the longest hydraulic flow path to the outlet(or design point)for each project DA, which accounts for slope, length, and ground condition/cover(see T,discussion below) • Storm Data—Input precipitation data for 2-year through 100-year, 24-hour duration storm events. • Mapping of the project DAs to the designated outfall point—Detention Basin P Based on comments on the Preliminary Design Report by Mr. Kimmi (comments dated February 10, 2010), the T,values for the project DAs were calculated using the procedure described in the USDCM Volume 1 Chapter 5—Runoff, with T,equal to the sum of the initial flow time (q)and overland flow time (ti), rather than the WinTR-55 method. These values were then input directly into the WinTR-55 model for calculation of the design storm runoff rates, hydrographs, and volumes. The 5-year stormwater runoff rate (QS_y,r)for the historical condition was calculated for the DA that included the overall Project Site boundary(or footprint)without inclusion of off-site runoff and assuming a zero percent impervious surface (USDCM allows for up to 2 percent impervious surface), which reduced the runoff coefficient C-value to 0.08. The calculated Q5_yr for the historical condition is 2.79 cfs. This 5- year value is critical since it denotes the maximum discharge rate that is allowed from the proposed Detention Basin P for the developed site condition. The 100-year stormwater runoff rates (Qioo_yr1 for the developed condition used in the design of proposed Channels T1 and P2 and the emergency spillway for Detention Basin P were calculated for the contributing DAs with T,values that include the off-site runoff that drains across the Project Site as required by the USDCM. The runoff generated from DAs T1 and P2 was used to design Channels T1 and P2, respectively, and the aggregate of runoff flows from all of the project DAs T1, T2, P1, and P2 (with off-site runoff)were used for the design of the emergency spillway(see Section 3.3.1 for additional details regarding design of the drainage channels and emergency spillway). The Qioo-yr for the developed condition used to design the Detention Basin P was calculated as a sum of the runoff flows for the contributing DAs with T,values that exclude off-site runoff in accordance with the USDCM. The aggregate of runoff flows from all Project DAs T1, T2, P1, and P2 (without off-site runoff) was used for the design of Detention Basin P(see Section 3.2.4 for additional details regarding design of the detention basin). It should be noted that based on the reconfiguration and grading of the Project Site I 3-2 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 layout, the runoff generated by DAs T2 and P1 flows directly into the detention basin without the need for conveyance through a drainage channel. The T,values for the developed condition Qioo-yr without off-site flow were calculated using the same hydraulic flow paths (or routes) used for design of the channels and spillway(with off-site runoff). However, the initial sheet flow lengths (maximum allowable length of 500 feet in accordance with USDCM procedure)corresponding to flow paths originating from off site were truncated at the edge of the Project Site boundary with only the remaining on-site sheet flow length up to the allowable 500-foot length accounted for in the equation. The remaining on-site hydraulic flow path length beyond the sheet flow limit was modeled as overland shallow concentrated and/or channel flow. This method is most representative of the hydraulic path from point of origin and the subsequent transformation of the flow characteristics from sheet flow to shallow concentrated and/or channelized flow. A summary table that includes the calculations for the Tr and the corresponding DA sizes and runoff flow rates has been provided in Table 1 for the historical condition, Table 2 for the developed condition including off-site runoff, and Table 3 for the developed condition not including off-site runoff.The historical and developed drainage area maps, including separate drawings of the developed DAs for the channels/emergency spillway and Detention Basin P, have been provided in the design drawings located in Appendix C. The USDCM T,design equations and corresponding figures and coefficients used for the runoff modeling have been provided in Appendix A. 3.2.4 Detention Discharge and Storage Calculation Methods and Computer Models • The Detention Basin P discharge flow rate and storage volume calculations for the Project design were calculated using WinTR-55 hydrologic modeling program and the standard unit hydrograph method. As previously discussed, the detention basin was sized for receipt and controlled discharge of the Qioo.yr flows for the developed condition excluding off-site runoff that drains across the Project Site. This is achieved by conveying the off-site runoff flow into the basin and then allowing the flow to pass through the emergency spillway, which was designed with the capacity to convey the developed condition Qioo-yr with off-site flow as described in Section 3.2.3. Based on the guidance provided in the USDCM and Weld County Addendum, the maximum allowable discharge rate from the proposed Detention Basin P for the developed site condition is equal to the OS_yr for the historical condition and must completely drain within 72 hours. Once the Q1oo-yr storm runoff hydrographs were calculated as described in Section 3.2.3, the WinTR-55 model was then used to hydraulically route the composite hydrograph through the proposed Detention Basin P configuration with associated outlet structure/pipe. The following are the WinTR-55 model inputs and outputs for the storage routing and design of the detention basin: • Basin Surface Area—Input of area (in acres)for the basin bottom and contour above bottom to define the basin storage geometry. Detention Basin P bottom area covers 2.142 acres with next higher 1-foot contour area covering 2.257 acres.The basin has been constructed with 4:1 (horizontal to vertical side slopes). • Outlet Type (Weir or Orifice)—Orifice flow was selected for this design. • Cedar Creek II Wind Farm Project 3-3 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • Outlet Diameter—An 8-inch-diameter outlet has been selected for this design; however, based on comments from Mr. Kimmi (dated February 10, 2010)a 10-inch PVC outlet pipe will be installed with an 8-inch orifice at the outlet of the pipe to facilitate future O&M of the detention facility. • Vertical Height from Invert of Outlet Pipe at Discharge Point to Bottom of Basin—Input of vertical distance from the start invert of the outlet pipe (bottom of basin)to the downstream invert of the outlet pipe at the discharge point is 0.5 feet for this design. Therefore, the slope of the discharge pipe is equal to the vertical height/length of 0.50 feet/57.5 feet, or 0.87 percent. • Outputs calculated by the model include peak outflow rate from the basin outlet pipe (1.83 cfs), basin storage volume(2.32 acre-feet), and maximum stage (or elevation)above basin bottom (1.05 feet). • Inflow and Outflow Hydrographs—the outflow hydrograph for the Qioo-yr event shows that the detention basin will drain the storage volume in 56.75 hours. The calculated 100-year storm event discharge rate (Q1oo-yr)through the Detention Basin P outlet pipe discharge orifice is 1.83 cfs, which is 0.96 cfs less than the maximum allowable Q5-yr of 2.79 cfs calculated for the historical condition of the Project Site as explained in Section 3.2.3. The maximum time required to drain the basin is 56.75 hours, which is less than the maximum allowable time of 72 hours. The detention basin embankment has also been designed to an elevation of 5,133.75 feet msl, which provides the required 1-foot freeboard distance above the 100-year water surface when the emergency spillway is conveying the maximum/emergency flow(see Section 3.3.1 for discussion of the emergency spillway). Therefore, the design for Detention Basin P meets the requirements as stipulated in the Weld County Addendum. As discussed in Sections 1.2.4 and 3.2.3, the Project Site was reconfigured after submission of the Preliminary Drainage Report. As a result, the site grading and detention basin layout/location were also modified to accommodate this revised configuration. In order to achieve a cost-effective, balanced cut to fill ratio for the Project Site, Detention Basin P has been designed as a relatively shallow basin (maximum 100-year stage of 1.05 feet deep)with a larger surface area to accommodate the 100-year storm event for the developed condition of the entire Project Site as shown in the design drawings in Appendix C. Based on a request by Mr. Sheffler(landowner), the detention basin outlet pipe has been designed to discharge to a 100-foot-long vegetated level spreader. The vegetated level spreader converts the concentrated pipe flow back to sheet flow through a zero percent bottom-sloped channel, which then gently discharges the stormwater as sheet flow over a newly constructed, low-lying, vegetated side slope (12:1 side slope)to the existing/vegetated pasture land. Refer to Sections 3.3.2, 3.3.3, and 4.4 for additional details regarding the outlet pipe, water quality, and vegetated level spreader, respectively. The WinTR-55 modeling output has also been provided in Appendix A. 3.3 Hydraulic Criteria 3.3.1 Conveyance Capacities The design for the Project Site proposes grass-lined, triangular channels (Channels T1 and P2)with a 3-foot constructed depth to collect both 100-year on-site and off-site runoff that passes through the 3-4 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • Project Site in DAs T1 and P2 and then convey that runoff along the northern edges of the site to the proposed Detention Basin P. The 100-year on-site and off-site runoff that passes through DAs T2 and P1 will be conveyed via overland flow directly into the Detention Basin P. Detention Basin P will provide controlled outlet/release of these flows and also provide an emergency spillway capable of passing the 100-year flow(including off-site runoff)as described in Sections 3.2.3 and 3.2.4. All of the hydraulic modeling (dimensions and flow characteristics)for this drainage design was performed using the Bentley Systems Flowmaster program (Version 08.01.68.00), which applies Manning's equation. The dimensions and flow characteristics were determined by entering Manning's roughness coefficient(n), slope (ft/ft), left and right side slopes, and designated 100-year discharge flows. Based on the guidance provided in the Weld County Addendum and USDCM, the newly constructed, grass-lined channels have been designed using the two different Manning's roughness "n"values calculated from the Retardance Curves provided in USDCM Volume 1, Chapter 7, Figure MD-9b (see Appendix E). This figure uses the product of velocity and hydraulic radius (R =flow area/wetted perimeter)to determine the respective Manning's "n"values corresponding to the selected retardance conditions: • Retardance C Condition—used for determining the maximum required channel capacity(or depth) with the assumption that the channel vegetation is fully grown. • Retardance D Condition—used for determining the maximum channel velocity(or controlling velocity) for newly constructed grass-lined channels with the assumption that the newly vegetated channels will not have mature grass and velocities will be higher that of the Retardance C condition. In accordance with the design procedure described in USDCM Volume 1, Chapter 7, each of the proposed Channels T1 and P2 have been designed for conveyance of the 100-year storm flow and satisfy the following UD&FCD channel hydraulic requirements: • Maximum flow velocity of less than 5 feet per second [fps]: Assuming the Retardance D condition, the maximum velocity for Channel T1 is 1.23 fps and for Channel P2 is 0.74 fps. • Maximum Froude Number of less than 0.5: Assuming the Retardance D condition, the maximum Froude number for Channel T1 is 0.24 and for Channel P2 is 0.16. • Maximum longitudinal slope of less than 0.6 percent: The maximum slope for Channel T1 is 0.32 percent and for Channel P2 is 0.29 percent. • Maximum side slopes of 4:1 (horizontal to vertical): maximum side slopes for Channels T1 and P2 are 4:1. • Minimum 1-foot freeboard: Each channel will be constructed to a depth of 3 feet. Assuming the Retardance C condition, the freeboard for Channel T1 is 1.0 foot and for Channel P2 is 1.24 feet. A freeboard variance request to Weld County is not required for this Project. Table 4 provides a summary of the proposed drainage channels' dimensions and flow characteristics and the Flowmaster Modeling Output for the channels has been provided in Appendix B • Cedar Creek II Wind Farm Project 3-5 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 In accordance with the USDCM and Weld County Addendum, the proposed Detention Basin P has been • designed with an emergency spillway that satisfies the following requirements: • Capable of conveying the peak 100-year storm discharge(including off-site runoff) draining into the detention basin: The emergency spillway has been designed for the Q100-yr flow(including off site flow) of 37.66 cfs. • Invert of the emergency spillway set equal to or above the 100-year water surface elevation: The emergency spillway invert has been set equal to the 100-year surface elevation in the detention basin at an elevation of 5,132.25 feet msl. • Depth of flow out the emergency spillway shall be less than 6 inches: The calculated flow depth for the emergency spillway is 0.46 feet(or 5.52 inches). The constructed dimensions of the spillway will be a width of 40 feet, invert elevation of 5,132.25 feet msl, and 4:1 side slopes to the top of the detention basin embankment elevation of 5,133.75 feet msl. • Minimum of 1-foot freeboard above the 100-year water surface elevation when the emergency spillway is conveying the maximum/emergency flow: The calculated freeboard for the emergency spillway(equal to the difference between the top of detention basin embankment and the surface elevation of the flow through the spillway) is 5,133.75 feet-(5,132.25 feet + 0.46 feet) or 1.04 feet, which is greater than the 1-foot minimum. • Effective erosion protection installed: See Section 4.4 for details regarding the emergency spillway erosion protection. Table 5 provides a summary of the proposed emergency spillway dimensions and flow characteristics, Table 6 provides a summary of the riprap calculations for the spillway, and Appendix B provides the • Flowmaster Modeling Output for the emergency spillway. 3.3.2 Detention Outlet Type The design for the Project Site will consist of one drainage basin, Detention Basin P. The proposed outlet type for the basin is 10-inch PVC outlet pipe (with a trash rack) and an 8-inch orifice at the discharge end of the pipe. The 10-inch pipe size and trash rack will facilitate future O&M of the detention facility. As described in Section 3.2.4, the Qioo-yr flow through the 8-inch outlet pipe orifice is 1.83 cfs and the slope of the outlet pipe is 0.50 feet in 57.5 feet or 0.87 percent. Based on the equation of flow rate equals velocity times flow area (or Q =VA), the velocity(V)through the outlet pipe (full-flow condition)for the 100-year storm is Q/A = 1.83 cfs/0.352 sf, or 5.20 fps. In accordance with the USDCM Volume 1, Chapter 7, Section 7.3, this outlet velocity of 5.20 fps is less than the maximum allowable velocity before riprap erosion protection is required for pipe outlets (maximum allowable velocity ranges from 5.5 to 7.7 fps depending on the erosive nature of the soils). Refer to Section 4.4 for additional explanation and details regarding erosion protection. Therefore, no riprap erosion protection is required for the outlet of the pipe. Based on a request by Mr. Sheffler(landowner), the detention basin outlet pipe has been designed to discharge to a 100-foot-long vegetated level spreader. The vegetated level spreader converts the concentrated pipe flow back to sheet flow through a zero percent bottom-sloped channel, which then gently discharges the stormwater as sheet flow over a newly constructed, low-lying, vegetated side slope (12:1 side slope) to the existing vegetated pasture land. Refer to Sections 3.2.4, 3.3.3, and 4.4 for • 3-6 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 . additional details regarding the detention basin, water quality, and use of level spreader and vegetated erosion protection, respectively. 3.3.3 Water Quality Outlet Configuration As stated in the Weld County Addendum to the USDCM, within Weld County the water quality capture volume(WQCV) shall be considered a portion of the total 100-year detention basin volume and must completely drain within 72 hours. The USDCM also recommends incorporating the capture and treatment of smaller-sized, less frequent storms (for sediment removal) into the design of the detention basin. It is recommended that these smaller storm volumes be captured and released in a minimum of 40 hours, but completely drained in less than 72 hours. For purposes of the Detention Basin P design, the 2-year storm event has been used as the smaller, more frequent storm to demonstrate compliance with this requirement. In order to satisfy the water quality and volume discharge criteria for both large (100-year storm)and smaller, more frequent storm events (2-year storm), Detention Basin P has been designed using the WinTR-55 hydrograph modeling method to capture, detain, and completely drain the detention basin through the 10-inch PVC outlet pipe with an 8-inch orifice at the discharge end for the 2-year and 100- year storm events. For the 100-year storm, Detention Basin P drains completely in 56.75 hours, which is less than the maximum allowable time of 72 hours. For the 2-year storm, Detention Basin P drains in 40.46 hours, which is greater than the minimum of 40 hours and less than the maximum of 72 hours. Therefore, based on this information the detention outlet type for Detention Basin P satisfies the water • quality outlet configuration for the 2-year and 100-year storm events. For data regarding the detention (or drain)times for the 2-year and 100-year developed condition in Detention Basin P, refer to the WinTR-55 model output and outlet hydrographs (graphical representation) provided in Appendix A. In addition to the minimum detention time of 40 hours for sediment removal as described above, the outlet flow from the detention basin also passes through a vegetated level spreader as previously described in this report. The vegetated level spreader converts the concentrated pipe flow back to sheet flow through a zero percent bottom-sloped, 6-inch deep channel, which then gently discharges the storm water as sheet flow over a newly constructed, low-lying, vegetated side slope(12:1 side slope)to the existing/vegetated pasture land. Therefore, this level spreader provides additional water quality treatment (or sediment removal)to the Project Site flows prior to discharge to the pasture lands and ephemeral drainage located to the north of the Project Site. Refer to Sections 3.2.4 and 4.4 for additional details regarding the detention basin and level spreader designs, respectively, and Appendix C design drawings for details regarding the vegetated level spreader. 3.4 Justification of Criteria or Calculation Methods The hydraulic structures proposed for the Project Site were designed in accordance with the guidance presented in the Weld County Code and associated USDCM. No other design criteria were applied to this design. • Cedar Creek II Wind Farm Project 3-7 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • 4. Drainage Facility Design 4.1 On-Site Drainage Patterns The runoff from the Temporary Construction Facilities Area (DA T1)drains from the southwestern corner to the northern edge of the Project Site at slopes ranging from approximately 0.8 to 1.0 percent. The runoff from DA T1 is then collected and conveyed through the grass-lined, triangular Channel T1 into the Detention Basin P, which is centrally located along the northern edge of the Project Site. The runoff from the Electrical Substation Area (DA T2) drains from the southwestern portion of the site to the northeast at slopes ranging from 0.8 to 0.9 percent with the runoff draining directly into Detention Basin P. The runoff from the O&M Building Area (DA P1)drains from the center of the Project Site starting along the southern edge and travels directly north at slopes ranging from 0.9 to 1.0 percent. The runoff from DA P1 also drains directly into Detention Basin P without the need for conveyance through a drainage channel. The runoff from the Concrete Batch Plant Area (DA P2) drains from the southeastern edge of the Project Site directly north at slopes ranging from 0.7 to 0.8 percent. The runoff from DA P2 is then collected and conveyed through the grass-lined, triangular Channel P2 into Detention Basin P. 4.2 Off-Site Runoff Compliance The Weld County Addendum and associated USDCM state that a proposed development must provide for safe conveyance of off-site flows through the Project Site and that off-site flows may be routed through • the emergency spillway or around the proposed detention facilities. As previously stated in Sections 2.3.3 and 2.3.4, Channels T1 and P2 and the detention basin emergency spillway have been designed to account for the safe and effective collection, conveyance, and controlled discharge of both on-site and off-site(combined/aggregate)flows for the 100-year stormwater event. The aggregate (or combined) 100- year flow rate from all of the drainage areas (including off-site runoff)for the emergency spillway is 37.66 cfs. Detention Basin P captures, detains, and releases the 100-year on-site runoff volume for the Project Site through the detention basin outlet pipe at a peak flow rate of 1.83 cfs, which is 0.96 cfs less than the 5-year historical condition peak flow rate of 2.79 cfs. The Project Site is located at the upper edge (or headwater)of a large unnamed ephemeral drainage that flows to the north and then northwest off the site.The aforementioned runoff generated from the Project Site that passes through the Detention Basin P outlet pipe (or the emergency spillway)will discharge to this unnamed drainage. This drainage passes under CR 135 through two, 4-foot-diameter corrugated metal pipes approximately 2,000 feet north of the site. As discussed with Mr. Kimmi on March 4, 2010, it is assumed that these two culverts have the hydraulic capacity to safely pass the existing runoff flows from the contributing areas of the major drainage basin (as described in Section 2.1.2)with both the Detention Basin P outlet pipe flow(which is 0.96 cfs less than the historical/existing flow condition) and the emergency spillway discharge from Detention Basin P. Therefore, there are no off-site runoff compliance issues identified for the Project site. For photographs of the downstream culvert crossings at CR 135, refer to Appendix K. • Cedar Creek II Wind Farm Project 4-1 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 4.3 Summary of Hydrology and Hydraulic Structures • The site plan layout(including the features described in Section 1.2.4), developed/proposed grading, detailed channel/basin/outlet pipe/spillway information, and the historical and developed DAs (including land use/surface details, developed condition slopes, hydraulic flow paths, etc.) are provided in the design drawings in Appendix C. The hydrologic and hydraulic design of the Project Site drainage structures have been previously discussed and summarized in Section 3.0. The O&M instructions for the proposed stormwater drainage facilities and erosion control measures have been provided in the design drawings in Appendix C. 4.4 Riprap and Erosion Protection As stated in the USDCM Volume 1, Chapter 7, the following are the maximum allowable velocities prior to required use of riprap erosion protection measures: • Grass-Lined Drainage Channels: 5.0 fps for erosive soils and 7.0 fps for erosive-resistant soils • Pipe Outlets: 5.5 fps for very erosive soils and 7.7 for erosive-resistant soils. As stated in Section 1.2.2, erosion factor K values for the Project area range from 0.15 to 0.17, which indicate a low erosion potential for the project soils. Although the Project soils are relatively erosive- resistant, Channels T1 and P2, the emergency spillway for Detention Basin P, and the outlet pipe for Detention Basin P have been designed so that the Qioo_Yr velocities have been kept below the velocity criteria for the erosive soils condition. The following is a summary of the drainage structure, associated flow velocity, and erosion protection • measures. • Drainage Channel T1: Q1oo_yr maximum velocity= 1.23 fps < 5.0 fps; construct with grass lining (see explanation of stabilization and re-vegetation below) • Drainage Channel P2: D100-yr maximum velocity= 0.74 fps < 5.0 fps; construct with grass lining (see explanation of stabilization and re-vegetation below) • Detention Basin P Emergency Spillway: Q1oo_yr maximum velocity= 2.04 fps < 5.0 fps; construct with grass lining to outlet downstream side slope (see details regarding riprap protection and re-vegetation of the outlet downstream side slope below) • Detention Basin P Outlet(8-inch Orifice): Qioo-yr maximum velocity = 5.20 fps < 5.5 fps; construct with outlet to grass-lined level spreader(see explanation of level spreader below) As required by the Weld County Addendum, in order to protect the emergency spillway from catastrophic erosion failure, buried riprap shall be placed from the emergency spillway downhill to the embankment toe of slope and covered with 6 inches of topsoil. The downstream side slope of the emergency spillway for Detention Basin P has been designed with Type L (D50 =9 inches) riprap erosion protection. The riprap size(Type L)was calculated using the procedure for riprap erosion protection at rectangular conduit (USDCM Volume 1, Figure MD-22)and with the gradation for Type Las shown in Table MD-7. The thickness of the riprap lining is two times the D50 diameter, or 1.50 feet. As required by the Weld County Addendum and USDCM, Type L riprap shall be mixed with 35 percent topsoil by volume and buried with 4-2 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • 6 inches of topsoil, vibrated, compacted, and then re-vegetated with an Weld County-approved vegetation seed mix(see explanation of re-vegetation below).Table 6 provides a summary of the riprap calculations for the downstream erosion protection of the emergency spillway. Refer to Appendix F for Figure MD-22 and Table MD-7. As previously described in this report, the detention basin outlet pipe has been designed to discharge through an 8-inch orifice to a 100-foot-long vegetated level spreader.The vegetated level spreader effectively converts the concentrated outlet pipe flow back to sheet flow for gentle discharge over the existing vegetated pasture land. The level spreader shall be constructed as follows: • Triangular channel configuration • Length = 100 feet • Depth of level spreader=6 inches • Zero percent bottom-slope (installed parallel to existing surface grade) • Upstream cut side slope =4:1 • Downstream outlet cut side slope = 12:1 • End of level spreader side slope up to existing grade =4:1 • Elevation of downstream edge (or outlet rim) < lowest elevation of upstream side slope • Erosion matting stabilization (see explanation of erosion matting below) • Re-vegetated grass lining of all cut slopes (see explanation of re-vegetation below) This level spreader configuration allows for the receipt of the outlet pipe discharge into a zero percent • grade, grass-lined, triangular channel that is constructed as described above.The water flow is then collected until it reaches a depth of 6 inches and is then gently discharged as sheet flow over the outlet edge/rim of the downstream outlet side slope to the existing vegetated pasture land. For construction details regarding the level spreader, refer to Sheet C104 of the design drawings in Appendix C. The following temporary and permanent soil erosion and sediment controls, stabilization, and re- vegetation measures will be used for the construction of the Project Site. • Re-vegetation—All disturbed areas, other than the gravel and impervious areas shown on the design drawings, will be re-vegetated using the seed mix as described in the Weld County Addendum for Areas North of Highway 14. The three road maintenance gravel stockpile areas will also be re- vegetated at the completion of construction. It is expected that the construction contractor will apply this seed mix using the hydroseeding method or other Weld County-approved method, if required. For areas that receive concentrated flows, a soil stabilization erosion mat will be used in conjunction with the seed (see erosion control/stabilization matting below). North American Green (NAG) is the suggested manufacturer of the hydroseeding product(HydraCM)that includes mechanically processed straw fibers, reclaimed cotton plant material, and proprietary performance-enhancing tackifiers to mitigate wind/water erosion and promote vegetative growth. The Weld County seed mix will be added to this product prior to application in the field. The areas to be re-vegetated and the specification for the Weld County seed mix are shown on the design drawings in Appendix C. • Temporary Erosion Control/Stabilization Matting—Temporary, biodegradable erosion control/stabilization matting will be installed in all disturbed areas that are to be re-vegetated and • Cedar Creek II Wind Farm Project 4-3 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 expected to receive concentrated stormwater flow(i.e., inner side slopes of the detention basin • adjacent to DAs T2 and P1 that receive overland flow directly from the Project Site, drainage channels T1 and P2, and the level spreader). The erosion matting will be installed in conjunction with re-vegetation measures using the seed mix specified by the Weld County Addendum as described above. NAG is the suggested manufacturer of the erosion matting product(Biodegradable Erosion Matting— Model S75); however, alternative erosion matting may be selected by the construction contractor, if approved by Weld County prior to installation. The stabilization calculations (permissible and calculated sheer stress)for the erosion matting were performed using NAG's proprietary engineering software. These calculations and product information have been provided in Appendix M. The erosion matting locations and installation details have been provided on the design drawings in Appendix C. • Temporary Silt fencing—Silt fencing will be installed on the downstream side of all disturbed Project areas to prevent transport of sediment from the Project site to the surrounding areas and ephemeral drainages. In addition, silt fencing will also be installed at the three road maintenance gravel stockpile areas during the construction phase of the Project. Temporary silt fencing will be inspected and maintained as described on the design drawings and removed from the designated areas only after the vegetation has matured and adequately stabilized the area. The locations of the temporary silt fence and the soil erosion and sediment control details and notes are shown on the design drawings in Appendix C. 4.5 Copies of Permit Applications Based on the design for the Project Site as described in this report, no Concentrated Animal Feeding . Operations; Division of Reclamation, Mining and Safety; or State Engineer's permit applications are required. A Colorado Department of Public Health and Environment (CDPHE) Stormwater Construction Permit is required for the Project. A copy of the CDPHE permit application has been provided in Appendix N. • 4-4 Cedar Creek II Wind Farm Project Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 5. Conclusions 5.1 Compliance with the Weld County Code The design for the Project Site stormwater drainage facilities meets the intent of the Weld County Code. 5.2 Drainage Concept 5.2.1 Effectiveness of Design The design as presented throughout this report was prepared in accordance with the Weld County drainage design requirements or other engineering methods and procedures as documented in this report. Based on the hydrologic and hydraulic calculations and modeling output(i.e., flow rates, velocities, and other flow characteristics), this design is effective in the mitigation and control of storm runoff damage. 5.2.2 Influence of Proposed Development As previously stated in this report, there is no Weld County Master Drainage Plan for this Project Site. 5.2.3 Irrigation Company Approvals Weld County may require that the applicant provide evidence that off-site impacted jurisdictions have been notified of the development.This requirement is not applicable to the Project. • Cedar Creek II Wind Farm Project 5-1 Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • 6.

However, in practice, the time of concentration can be an empirical value that results in reasonable and acceptable peak flow calculations. The time of concentration relationships recommended in this Manual are based in part on the rainfall-runoff data collected in the Denver metropolitan area and are designed to work with the runoff coefficients also recommended in this Manual. As a result, these recommendations need to be used with a great deal of caution whenever working in areas that may differ significantly from the climate or topography found in the Denver region. For urban areas, the time of concentration, tc, consists of an initial time or overland flow time, t;, plus the travel time, t„ in the storm sewer, paved gutter, roadside drainage ditch, or drainage channel. For non- urban areas, the time of concentration consists of an overland flow time, t;, plus the time of travel in a defined form, such as a swale, channel, or drainageway. The travel portion, t„ of the time of concentration can be estimated from the hydraulic properties of the storm sewer, gutter, swale, ditch, or drainageway. Initial time, on the other hand, will vary with surface slope, depression storage, surface cover, antecedent rainfall, and infiltration capacity of the soil, as well as distance of surface flow. The • time of concentration is represented by Equation RO-2 for both urban and non-urban areas: tc, =t. + t (RO-2) in which: t,=time of concentration (minutes) t;= initial or overland flow time (minutes) t,= travel time in the ditch, channel, gutter, storm sewer, etc. (minutes) 2.4.1 Initial Flow Time The initial or overland flow time, t;, may be calculated using equation RO-3: 0.3951.1—Cs� t (RO-3) ) in which: t;= initial or overland flow time(minutes) C5 = runoff coefficient for 5-year frequency(from Table RO-5) • 2007-01 RO-5 Urban Drainage and Flood Control District RUNOFF DRAINAGE CRITERIA MANUAL (V. 1) • L = length of overland flow(500 ft maximum for non-urban land uses, 300 ft maximum for urban land uses) S= average basin slope (fUft) Equation RO-3 is adequate for distances up to 500 feet. Note that, in some urban watersheds, the overland flow time may be very small because flows quickly channelize. 2.4.2 Overland Travel Time For catchments with overland and channelized flow, the time of concentration needs to be considered in combination with the overland travel time, r„ which is calculated using the hydraulic properties of the swale, ditch, or channel. For preliminary work, the overland travel time, t„ can be estimated with the help of Figure RO-1 or the following equation (Guo 1999): V=C,.S„as (RO-4) in which: v=velocity(ft/sec) C,=conveyance coefficient(from Table RO-2) =watercourse slope(ft/ft) Table RO-2—Conveyance Coefficient, • C, Type of Land Surface Conveyance Coefficient, C,, Heavy meadow 2.5 Tillage/field 5 Short pasture and lawns 7 Nearly bare ground 10 Grassed waterway 15 Paved areas and shallow paved swales 20 The time of concentration, t,, is then the sum of the initial flow time, t;, and the travel time, t„ as per Equation RO-2. 2.4.3 First Design Point Time of Concentration in Urban Catchments Using this procedure, the time of concentration at the first design point(i.e., initial flow time, t,) in an urbanized catchment should not exceed the time of concentration calculated using Equation RO-5. t = 180 + 10 (RO-5) in which: tc.= maximum time of concentration at the first design point in an urban watershed (minutes) • RO-6 2007-01 Urban Drainage and Flood Control District DRAINAGE CRITERIA MANUAL(V. 1) RUNOFF • Table RO-3—Recommended Percentage Imperviousness Values Land Use or Percentage Surface Characteristics Imperviousness Business: Commercial areas 95 Neighborhood areas 85 Residential: Single-family * Multi-unit(detached) 60 Multi-unit(attached) 75 Half-acre lot or larger * Apartments 80 Industrial: Light areas 80 Heavy areas 90 Parks, cemeteries 5 Playgrounds 10 Schools 50 Railroad yard areas 15 • Undeveloped Areas: Historic flow analysis 2 Greenbelts, agricultural 2 Off-site flow analysis 45 (when land use not defined) Streets: Paved 100 Gravel (packed) 40 Drive and walks 90 Roofs 90 Lawns, sandy soil 0 Lawns, clayey soil 0 * See Figures RO-3 through RO-5 for percentage imperviousness.

Basic requirements for riprap stone are as follows: • Rock shall be hard, durable, angular in shape, and free from cracks, overburden, shale, and organic matter. • Neither breadth nor thickness of a single stone should be less than one-third its length, and rounded stone should be avoided. • The rock should sustain a loss of not more than 40% after 500 revolutions in an abrasion test(Los Angeles machine—ASTM C-535-69)and should sustain a loss of not more than 10% after 12 cycles of freezing and thawing (AASHTO test 103 for ledge rock procedure A). • Rock having a minimum specific gravity of 2.65 is preferred; however, in no case should rock have a specific gravity less than 2.50. 4.4.1.2 Grouted Boulders Table MD-8 provides the classification and size requirements for boulders. When grouted boulders are used, they provide a relatively impervious channel lining which is less subject to vandalism than ordinary riprap.

Area-depth adjustments are given in the Atlas for durations of 1-, 3-, 6-and 24-hours. Figure RA-14 was based on a similar figure in the NOAA Atlas. The 15-minute curve was extrapolated by the District from the information shown for other storm durations on Figure RA-14. The fast response times of urbanized watersheds and sharp rainstorm distribution gradients in the Denver area require adjustments of rainfall depths for storm durations that are less than %-hour. • RA-4 01/2004 Urban Drainage and Flood Control District Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • Appendix I: NRCS Soil Reports • • Cedar Creek II Wind Farm Project en 0 in O izt O V cp• 096££57 006££57 058££94 008££57 0SL£ES7 00L££54 059££57 w ..£4 .97 £0L r „£7 .9t7 !COL o O re. r.4144:411 - • ar In OC0 Ni I lb 5 . a i iii.titiii• iiti , % .4000 •% -1.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet. and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B. C, and D) and three dual classes (A/D. B/D. and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly • wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table. soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D. or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

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 (Ksat). 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. • "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.'

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (ND, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. • Group D. Soils having a very slow infiltration rate (high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (ND, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.

Each pallet contains 40 bags or one ton with a plastic pallet cover for enhanced protection from rain and UV rays. Manufacturing: HydraCM is manufactured exclusively for North American Green by Mulch &Seed Innovations, LLC, Centre, Alabama. HydraCM is manufactured within a set of quality guidelines established after years of product development and rigorous testing in varying conditions. Application Instructions*: 1. Fill tank of a mechanically agitated hydroseeding machine with sufficient water to suspend seed and fertilizers.Add soil amendments. 2. Continue to add water slowly while adding HydraCM at a steady rate. Mix at a rate of 50 lbs of HydraCM per 100 gallons of water. 3. Agitate for a minimum of fifteen minutes after adding the last amount of water and HydraCM. 4. Apply in a uniform layer from two opposing directions to ensure complete soil coverage. Use loading chart to determine the proper application rates. Irregular surfaces may need slightly higher application rates to obtain adequate coverage. 5. Clean equipment properly to ensure HydraCM is removed from the pump, tank, and hoses. Not for use in channels, swales, or other areas where concentrated flows are anticipated, unless installed in conjunction with a temporary erosion control blanket or permanent reinforcement mat. HydraCM may be applied on saturated surfaces. Do not allow foot traffic or grazing on treated areas until vegetated. Be cautious of slippery surfaces while applying. Warning: Do not store near an open flame or heat source. Use caution when stacking units. * See Installation guide for more detailed information regarding application of the HydraCM • Updated 10/2008 GREEN" , Installation and Application Guide f .5d SUBSTRATE AND SEEDBED PREPARATIONS 1.

Use caution when stacking units. 14649 Hwy 41 North• Evansville, IN 47725 . 800-772-2040. 812-867-6632 • Fax: 812-867-0247• www.nagreen.com Updated 10/2008 NORTH • , GFEEN- ff Oil Helpful Tips for Use of High Performance Hydromulches • HydraCM is most easily introduced to the slurry by cutting the lower portion of the bag on 3 of the 4 sides, thus leaving the bottom portion of the bag attached. Next, make a slit in the upper portion of the bag to create an air hole, allowing the HydraCM to drop into the tank for instant agitation. • Avoid dropping the bag, a piece of the bag, or any foreign objects into the slurry. If this should happen, is imperative to stop the machine before the object reaches the pump. • Agitate HydraCM for a minimum of ten minutes then reduce the paddle speed to a slow roll to prevent cavitations. • Maintain paddle speed during the application process. • Avoid blasting the soil's surface during application by utilizing the appropriate nozzle. For short distance applications use a fan-tip nozzle. Using a long distance nozzle at close • range could significantly alter the soil's surface. • All hydroseeders have a bypass valve that increases/decreases the amount of pressure within the lines. Most erosion control professionals choose not to use the bypass valve due to its sensitivity. Instead, the pressure is adjusted by fluctuating RPMs of the motor accordingly. • After applying the mulch in opposing directions, it is beneficial to spray the mulch upward in a lofting manner to produce a cap for the mulch's surface. • The green dye in HydraCM is UV sensitive, which will allow the green color to fade in approximately in seven days. However, avoid spraying houses, mailboxes, cars and other objects directly with HydraCM. • Lubricate the hose at the beginning of filling process (water filling stage before adding mulch or additives) by opening the nozzle valve and pumping only water through the hose. Turn the nozzle valve off trapping water in the hose. This lubricates the hose and assists in preventing hose clogs. • 14649 Hwy 41 North•Evansville,IN 47725 . 800-772-2040. 812-867-6632 • Fax: 812-867-0247•www.nagreen.com Final Drainage Report Wind Energy Facility and 230-kV Transmission Line USR 1723 • Appendix N: CDPHE Permit Application • • Cedar Creek II Wind Farm Project STATE OF COLORADO For Agency Use Only N•..

INTRODUCTION This study updates the January 20, 2010 Traffic Impact Study for Cedar Creek II Wind Farm in Weld County, Colorado. It incorporates recent project updates and refinements, and County comments on the earlier study. Recent decisions on material sources, haul routes and operating strategies are expected to reduce site traffic; however traffic used in this study is consistent with the earlier study, thereby presenting a conservative analysis. This approach was discussed with the County and approved. The study assesses current area roadway operations, operations during construction of Cedar Creek II, and long-term operations and maintenance with Cedar Creek II fully functional. Cedar Creek II is located between the existing Cedar Creek I Wind Farm and State Highway 71 (SH 71), some 17 miles north of New Raymer. It covers almost 27,000 acres; about 3% of the site will be disturbed during construction and less than 0.5% will be disturbed after construction. The wind farm will have turbines capable of generating • up to 300 megawatts (MW) of electricity that will be transmitted into the existing trans- mission line segment that runs from the Cedar Creek I substation. Primary site access will be provided by SH 71 connecting to County Roads (CR) 120 and 132 and the network of county roadways serving this area. A vicinity map is presented on Figure 1. Key work tasks undertaken as part of this effort are described below. • Obtain current traffic and roadway data in the immediate area of the site. • Determine and evaluate traffic conditions during construction. • Develop and assess conditions after construction with Cedar Creek II fully built and operational. • Evaluate traffic operations and other critical issues during construction and the long term. • Identify areas of potential deficiencies. • Recommend measures to mitigate the impact of site-generated traffic as ap- • propriate. 1 - �h�/ -- ESE dO �� I eR_, '�. •1 N N e 0 r e r C N cc sftan o cco at- -v,E_ in w en c\1/4.1'..Th 1 6:7 I- In CV Q7 3 II L `.- 8 of, —, V4 r a r v Ln C.) 0 k' / 1 - 54 �► 1 lye ek } a I co --r— CC U TI - '_t HO g I i i a - i. 9 ££1 83 A ££l a3 (- U i _ .. who 4,0 U 6t t HO Ri CI- I N 0 - < a I Lz1 a3 �- U C 0 0 St 1 80 i F 0 CC 9z1 a3 m - Ll._ o U co N e cc m - U CC CC 0 U A cc \ 611a� stt 83 0 c L1183 co �% N Rstl 80 cc p? — u U £l l 83 I 111 83c , C0 ,- a 1 111 83 JO a M U - z C) - N 5 •.

AGENCY DISCUSSIONS At the onset of this study, Weld County and the Colorado Department of Transportation (CDOT) were contacted. Several discussions with County staff and Gloria Hice-Idler, representing CDOT, resulted in the following agreed-upon items: • The County asked for information and analyses focusing on construction which is expected to be the timeframe associated with peak traffic. This in- formation, while preliminary, and based upon a number of construction as- sumptions, will help form the framework of the roadway maintenance agreement. • It was requested that all items identified in the County's Traffic Study scope of work (Appendix A) be addressed even if specific items are simply identi- • fled as not being applicable. • The County suggested that daily traffic counts be conducted for roadways for which the County did not have counts available. • The need for acceleration and deceleration lanes at the SH 71 intersections with CR 120 and CR 132 should be fully investigated using State Highway Access Code criteria. Per the Access Code, conditions after construction will need to be fully assessed in the long term. • Weld County specifically asked for sight distance evaluations at critical inter- sections along the haul route and a list of improvements needed to serve large vehicles. These items are included or discussed in the various sections of this study. • 3 III. CURRENT CONDITIONS A). Current Road Network SH 71 is the major roadway serving this area and is supported by a network of County roads. It is a north-south paved roadway extending north from SH 14 into Nebraska, the town of Kimball, and beyond. SH 71 has one lane in each direction and a posted speed limit of 65 miles per hour (MPH). Some 580 vehicles per day currently use SH 71 in the area of Cedar Creek II. SH 71 is a rural regional highway designated as an RA roadway by the State Highway Access Code. CR 120 and CR 132 intersect SH 71 at full-movement, stop-sign-controlled intersec- tions. They extend west of SH 71 and connect to a number of other County roadways. To the east of SH 71, both CR 120 and CR 132 are considered field approaches. All applicable County roads are gravel roadways and are designated local roadways. They • have one lane in each direction and there are no posted speed limits. The County roadway network is somewhat discontinuous in the area of the project. Current roadway geometry at the SH 71 access intersections is shown on Figure 2. Sight distances are acceptable at the SH 71 intersections. Sight distances at key inter- sections along the proposed haul route were field reviewed. It was determined that all intersections have sufficient sight distance for site traffic travelling at 40 MPH, the BP imposed speed limit for all site vehicles. Vehicles travelling at 55 MPH, the County's legal speed limit, will have sufficient sight distance at all intersections except the CR 120—CR 135 and CR 126—CR 129 intersections. Sight distance analyses at intersections such as turbine access roads, haul routes, and County roads will be completed as part of the final project layout and design based on CDOT standards. 4 • 2 4ed. 44 cc DS itt CR132 / re 742,9 n re K • CR120 S CR116 W m re U • r Figure 2 CURRENT ROADWAY GEOMETRY 5 • B). Current Traffic Conditions Peak hour and daily traffic counts were undertaken in conjunction with this study. Traffic was counted on SH 71 at the CR 120 and CR 132 intersections between the hours of 7:00 AM and 9:00 AM and 4:00 PM and 6:00 PM to frame the typical highway morning and afternoon peak hours. The high continuous peak hour within the two-hour count times represents the morning and afternoon peak hour. Peak hour traffic is shown on Figure 3 and daily traffic on Figure 4. Count sheets are provided in Appendix B. Since current peak hour traffic demands are minor on SH 71 and insignificant on CR 120 and CR 132, it can be stated that operating levels of service are at level of service (LOS) "A" during both peak hours. C). Surrounding Land Uses Most land uses surrounding the site are rural and agricultural in nature; however, the • Department of Defense (DOD) also has a number of missile sites in the immediate area. The DOD has a maintenance agreement with Weld County to ensure that critical road- ways are readily available for use. Missile routes that overlap the roadways that Cedar Creek II will use include CR 132 and CR 116 and segments of CR 127, CR 133, and CR 135. IV. SITE ASSUMPTIONS Cedar Creek II will be built in one construction phase starting in mid-2010 with comple- tion approximately 10 months later. When completed, it will be a network of turbines and transmission facilities. It will be served by the existing County roadways and a network of string roads providing access to each turbine. A concept plan is presented on Figure 5. • 6 • 2 M N p Q u ` 1/1 Cl 1 0/1 rn N CR 132 1 a re a Cip 4 in re 7.2e in m v re a • CR 120 "`_"`_` o N ti) 1 1/0--l' 1) 1 n 0/1 —).

C.) • Q) 61183 V r 9 Traffic activity associated with the development of Cedar Creek II will consist of three . distinct elements. They are (1) importing materials and equipment, (2) construction, and (3) operations after construction. Each element is described in the following sections. A). Haul Routes Haul routes have been identified based on the location of water and gravel sources. Given the location of these sources, some traffic will originate onsite but most trucks will use SH 71 to access Cedar Creek II. Turbine haul routes are expected to use either Interstate 80 (1-80) or 1-76 leading to SH 71. Anticipated haul routes are shown on Figure 6. B). Site Access and Circulation Two access and circulation schemes are proposed for Cedar Creek II. The first is designed to accommodate large loads during construction based on the B&K Trucking survey. The second will serve other construction traffic and operations and maintenance (O&M) traffic after construction is completed. Each scheme is outlined below. Construction Traffic A construction access and circulation plan has been prepared as shown on Figure 7. This plan was developed to provide all large loads, such as the turbine components, a safe and efficient network of one-way roads to access and circulate through the site. Large vehicles will travel west on CR 132 from SH 71 to CR 135 and south on CR 135. As vehicles approach CR 130, they can either proceed south on CR 135 or turn west on CR 130. Vehicles proceeding south on CR 135 will turn east on CR 120 to SH 71. Vehicles going west on CR 130 will turn south on CR 131, west on CR 126, south on CR 127, east on CR 116, north on CR 133, and east on CR 120 to SH 71. These routes form a one-way circulation scheme entering on CR 132 and exiting on CR 120. 10 I 1 • N W \ ESL a0 C to -I y'646 HO T� ✓�— 69l a� m p 691 HO u Q H 2 u W Q49 cc U d te c u IL HS re U 141 aO N en z u u • F£l HO C£L HO ICI MO 0 Ct CU 6ZL HO N 2 en te0 a) U U U d re 0- al.a0 w co CO SZl 110 U _ a) (7 rc > U 1p N • \ c M143 \7 a° • LII HO o i • ♦ 11 \ • / ESL NO g64L SO 641 HO s4L as to 4, 1 m U 4� V ♦ LL HS 0 O 7 �. 5 A co N l4LHO N C= 1r _ LL Q� n r N W re tJ U U Q ♦ • • N � V EEL HO ,££L ISO , • LEL HO V 6Z1 aO u '' C U U ♦ al HO m rc u SZL HO N cu LT `o c g t o ° rem U .o 3 = V N V T O . w 6LL HO p 2 o Z W W m o O J Z UL NO • 12 • Improvements such as increasing turning radii, structural strengthening, and obstacle removal will be made along these routes and other routes leading to the site, as identi- fied in the B&K Trucking survey of the internal and external haul routes. Potential improvements were recently refined based on a site survey conducted by BP, GE, and B&K Trucking. This survey resulted in identification of improvements needed to serve large vehicles. The list of identified spot improvements is provided in Appendix C. All large loads will be escorted by pilot vehicles and meet all legal requirements. The indicated routes provide service to the primary substation located in the northeast corner of the CR 132—CR 135 intersection. Three substations were assessed in the earlier study; therefore, a traffic reduction is anticipated. The routes also provide con- nections to the planned network of string roads serving the individual turbines. Planned access and circulation routes and the substation location are shown on Figure 7. Since the County has taken the position that speed limit reductions will not be allowed, BP will • direct all site traffic to travel at speeds of 40 MPH or less when onsite or using County roads. Although not legally enforceable, this action will promote safety and minimize dust. Sight distances at critical intersections were also reviewed along the access and circula- tion routes. This effort determined that all intersections have adequate sight distance for the BP imposed site traffic speed limit of 40 MPH. Given the County's legal speed limit of 55 MPH, sight distances remain adequate since good lines of site are available over most vegetation. Deficiencies were found at two locations. One location is the CR 120— CR 135 intersection where sight distances are limited by vertical curves on CR 120 on both the east and west sides of CR 135. Because this intersection will serve both haul routes, further review was undertaken. The northwest corner will be modified to allow easier turns for large trucks. This will likely improve sight distance from CR 135 to the west along CR 120 but not to the level to accommodate 55 MPH traffic. In the interest of safety it is suggested that temporary all-way stop sign control be implemented during construction and conditions returned to normal after construction. Alternately, temporary • 13 stop sign control for southbound CR 135 traffic and a 40 MPH speed limit on CR 120 • approaching CR 135 could be implemented in both directions. The second deficiency is sight distance on CR 129 to the east of CR 126. This could be remedied by reducing the westbound speed limit on CR 129 as it approaches CR 126 to 45 MPH and installing a temporary stop sign on CR 126. In the interest of enhancing safety, the County should reconsider its' previous decision to maintain 55 MPH speed limits, and allow 40 MPH construction speed limits on all area roads. This temporary reduction will improve conditions at the two intersections, discussed above, and improve safety throughout the work zone. Normal sized trucks and smaller vehicles are expected to use the haul routes since these roadways form the framework of the area roadway network. While use of other public roadways cannot legally be restricted, BP will promote using the haul road net- work. • The area near the substation is expected to serve as the project headquarters. As such, most material and component drivers will need to check in prior to being dispatched to another location. It is also expected that all workers will report to this area when arriving at work and will depart from this area at the end of the shift. Two driveways to CR 132 and one driveway to CR 135 are planned for this area during construction. Operations and Maintenance Once construction has been completed, roadways will be restored to a condition agreed to by Cedar Creek II and Weld County and function normally. At that time, O&M per- sonnel will be based in the area of the substation. The design of this area will be evolv- ing through the preliminary design phase. A single driveway to CR 132 will provide access to the O&M area. 14 • V. SITE TRAFFIC Cedar Creek II site traffic will generate construction traffic and normal operations and maintenance traffic after construction is complete. Site traffic in each phase is described in more detail below. A). Construction Traffic Construction traffic will occur over an approximate 10-month construction period. During this time, up to a 300 MW wind farm will be constructed. Activities are expected to generally commence in the following order with some overlap: 1. Grade site for construction staging (includes creating parking area and setting up construction trailers). 2. Begin constructing access roads. 3. Begin installing the energy collection system. 4. Begin constructing foundations. • 5. Begin receiving deliveries of equipment. 6. Begin building substation/O&M building. 7. Erect wind turbines. 8. Restore the site. The above-described work is planned to commence in mid-2010. Work will normally occur during daylight hours up to six days per week. This will result in a 10- to 12-hour shift each day. This schedule may be extended if circumstances re- quire working seven days per week, there are weather delays or schedule slippages, or emergency repairs are needed. Additionally, large loads may travel at night, thereby reducing conflicts with other vehicles. Up to 250 workers will be working on this project. Construction will start with the building of new roadways and making spot improvements to the current roadway system as needed to facilitate large loads. Anticipated spot improvements, as known at this time, are provided in Appendix C. Tracking pads of • sufficient length to permit a full tire rotation will also be provided where appropriate. 15 Construction activity will increase up to month four, which is expected to represent the • peak time. After month four, it is expected to drop significantly and drop to the lowest level over the last three months. Assuming a mid-2010 start, peak construction activity is expected to occur during the months of July, August, and September. Monthly site traffic was calculated for each month of construction based on owner-provided informa- tion and the following assumptions: • Up to 250 workers will be needed for this project in the peak month. During other months, the number of workers will be proportionate with site traffic activity. It was also assumed that no fewer than 100 workers will be onsite at any time. • Given the lack of populated areas near the site, workers may decide to carpool. Three workers per vehicle were assumed. • Once onsite, workers will remain onsite for their entire shift. • Roadway repair material will be stockpiled onsite at one or more locations de- pending on strategic needs, construction activities, and legal limitations. Each stockpile will have 1,000 cubic yards of material. Since the earlier study assumed • each stockpile would have 3,500 cubic yards of material, site traffic will be re- duced. • Site traffic will be equally distributed on the north-south directions on SH 71. Resultant monthly construction-related round trips are shown on Table 1. • 16 • Ti0 O O N OO) 7 OO) 0O 0)0 (O O N a O M O O CO N F (D O O r us y r O (O O O CO OO OO (O CO co on 0) O 0) ro 0 OO) m O O O O O Ow Ow OO) OO) m CO O O 0o O O) o 0 O O) n co co m O v a v r N r r M, O o (o o O ,.. o v a v 'O = r N r r M s- c H O 2 N o O O m O O O )O C coM O C V V (0 O O r r N r r (+j U 0 bO O O O O 0 0 O 0 0 ct M (0 (0 r(O (OO 0 C o CO ui N C r N ' r N co .E • 0 O O U O O 0 (0 a o o M N O �- (' o o n v o v o v 'o .o r N V r N (O `a C "O L co O N N M 0 O xl-a MO OO O 7 1E CO (D M N V O N O) CO C O rCN OO O co r O O O Lo r M N O O(O M O) O) V o t r O O a) 0 E nSZI c R3 H To > 0 C co o v _c N a r a m 3 s a o N N -J J Q N Q N co Y D 0 Q o OC U t. sa a >no E d C 2 x F S 0 coC 3 F 0 O O H T ~ Za O O O v 0 o `y t O d o O K U t > m a m C C L 0 O O m m M ( 2i F . 0 0 J 3 s to O a o d O r lO r C • O a 0 0 tU (0 0 0 (0 t0 N 0 O C F C C C C C C K n a) d o d o o `m Cl.) d Ls! H w w w w w w 17 • Based on the provided information, the following peak hour and daily traffic is ex- pected for the high, average, and low construction months (Tables 2 through 4). Peak-hour traffic assumes all workers arrive and depart the site at the same time. Other traffic is assumed to occur uniformly over a 10-hour workday. These assump- tions present the worst-case peak-hour traffic conditions and have been rounded to the nearest five vehicles. One-way trips are presented, instead of round trips as shown earlier, to facilitate operational analyses at key locations. Table 2.

On average, 75 morning and afternoon peak-hour trips and 300 daily trips will occur. • 18 • Daily traffic assignments for the high and average construction months are shown on Figures 8 and 9, respectively. Peak-hour site traffic assignments were also developed for the high and average construction months. This information is shown on Figures 10 and 11 for the high and average construction months, respectively. B). Operations & Maintenance Traffic Site traffic will be significantly less after construction is completed and normal O&M operations commence. An estimated 12-14 employees will work at Cedar Creek II from about 8:00 AM to 5:00 PM, Monday through Friday. They will be responsible for routine operations and maintenance. Emergency operations may occur outside normal working hours. Anticipated peak hour and daily traffic is shown in Table 5. The indicated traffic assumes that employees do not carpool and arrive independently. Table 5.

This level of activity is expected for the foreseeable future. Equal distribution is assumed on SH 71 between the north and south. Daily site traffic for O&M activities is shown on Figure 12, with site peak-hour traffic for the same timeframe shown on Figure 13. • 19 • !

Background Traffic Background traffic was developed using straight-line growth based on CDOT pub- lished growth factors for this section of SH 71. Traffic growth on County roads is expected to be insignificant. Background peak hour traffic is shown on Figures 14 and 15 for the construction and O&M timeframes, respectively. B). Total Traffic Total traffic was developed for each future evaluation year. Total traffic is the combi- nation of site and background traffic. Total traffic is shown on Figure 16 for peak hours during construction; total daily traffic during construction is shown on Figure 17. It • should be noted that Figures 16 and 17 reflect conditions during the peak construction month. Total traffic for representative O&M operations is shown on Figure 18 for peak hours and on Figure 19 on a daily basis. C). Roadway System Short-term and long-term roadway features were estimated using known or planned improvements along SH 71. Since no planned improvements are anticipated, the existing roadway geometry and striping was retained through the long term. • 26 • 2 lC al es CC u CR132 // a re a C4) N rc a m e re U • M CR 120 Z iii N - Al N/N 1) 1 N/N Z o y CR 116 Zin N Of e re U • LEGEND: AM/PM Peak Hour N= Nominal Figure 14 NOTE: Rounded to nearest 5 vehicles.

Construction and long-term O&M conditions were evaluated. At the onset of these undertakings, peak-hour traffic was reviewed at each location to identify the need for new auxiliary lanes or an upgrade in traffic controls. Findings for each timeframe are documented in the following sections. A). Construction A review of peak traffic was conducted to determine the need for auxiliary lanes at the SH 71-CR 120 and SH 71-CR 132 site access intersections. CDOT's State Highway • Access Code auxiliary lane criteria for RA roadways and the existing 65 MPH speed limit were used in this assessment. It was determined that no improvements would be warranted on SH 71 at the CR 120 and CR 132 intersections because virtually all side street traffic will be construction related and therefore considered a temporary use. A review of traffic using the CR 120 and CR 132 intersections with SH 71 determined that stop-sign control is appropriate at these intersections since traffic signals will not be warranted. Operating conditions during the peak construction month were assessed using highway capacity analysis procedures. Resultant levels of service at the key access intersections during construction of Cedar Creek II are shown in Table 6. • 33 • Table 6. Construction Levels Of Service Movement/ Level of Service Intersection Control Direction AM PM SH 71-CR 120 Stop NB LT A A EB LR A B SH 71-CR 132 Stop NB LTR A A SB LTR A A EB LTR B A As shown, all traffic movements will operate at LOS "B" or better; therefore, very acceptable operations are expected during construction of Cedar Creek II. Capacity worksheets are presented in Appendix D. All internal intersections with County roads are expected to operate acceptably given the small amount of traffic at those loca- tions. •B). Operations & Maintenance A review of long-term peak hour traffic determined that no auxiliary lane improve- ments will be warranted at the site access intersections with SH 71 during normal operations at Cedar Creek II. Consequently, the current roadway geometry was retained through the long term. Total peak-hour traffic was loaded onto the current roadway geometry to reflect 2030 conditions. Resultant operating levels of service are shown in Table 7. • 34 Table 7. O&M Levels Of Service Movement/ Level of Service Intersection Control Direction AM PM SH 71-CR 120 Stop NB LT A A EB LR A A SH 71-CR 132 Stop NB LTR A A SB LTR A A EB LTR A A As indicated above, the site access intersection will operate acceptably in the long term. Capacity worksheets are available in Appendix E. • VIII. OTHER ISSUES A). School Buses Prairie RE-11 School District was contacted regarding its school bus routes and schedules in the area of Cedar Creek II. These issues were discussed with Joe Kimmel, the District Superintendent. Generally, school is open four days per week (Monday through Thursday); school is open on Fridays when needed to meet atten- dance requirements. The school is located in New Raymer and serves students from preschool through grade 12. School hours are 7:50 AM to 3:35 PM from late August through late May. No summer classes are held. Currently, the school district serves only one family in the area of the proposed pro- ject. This family lives just north of CR 134 on CR 125. Per Mr. Kimmel, the school bus driver uses CR 127 to access CR 125 and proceeds north to the residence and returns to New Raymer using the reverse route. Pick-up time is roughly 7:15 AM, with • drop-off around 4:15 PM. Part of the time, the student resides in New Raymer. 35 Given the frequency and duration of school buses in this area, no significant conflict • with site traffic is expected. This is reinforced by the fact that school will not be in session during approximately one-half of the peak construction time. B). Dust Mitigation Cedar Creek II will use a number of unpaved County roads during construction of the wind farm. County policy indicates that roadway segments with annual average daily traffic (AADT) exceeding 200 vehicles per day should be treated to inhibit fugitive dust. In this instance, only the following roadway sections are expected to exceed 200 vehicles per day during the peak construction month: • CR 132 from SH 71 to CR 135 • CR 135 from CR 132 to CR 130 A more detailed analysis was conducted on these two roadway segments both during and after construction. Average daily traffic was calculated for the different levels of activity as shown in Table 8. • Table 8. Average Daily Traffic Total Daily Traffic Peak Average Post Construction Construction Construction Roadway Section Month Month Month AADT CR 132 SH 71-CR 135 430 290 90 255 CR 135 CR 132-CR 130 290 170 20 145 As shown, only CR 132 will average more than 200 vehicles per day during 2010. When construction has been completed, no roadway segment is expected to exceed 90 vehicles per day. This number is well below the 200 vehicles per day threshold when dust mitigation should be considered. • 36 • County dust control mitigation treatments include: 1. Surface treatment using dust control agents 2. Six-inch-thick stabilized aggregate base using dust control agents 3. Paving 4. Speed limit reductions 5. Periodic watering Because dust mitigation will only be needed during construction and all site traffic will be restricted to 40 MPH, the dust mitigation measures shown in Table 9 are reason- able during construction. Table 9. Dust Mitigation Measures Roadway Section Dust Mitigation CR 132 SH 71-CR 135 Surface treatment CR 135 CR 132-CR 130 Surface treatment or watering Others Varies Watering as needed • After construction is completed or significantly reduced, no further dust control mitiga- tion will be needed. C). Department of Defense The DOD has a number of missile silos in this area that are accessed using a portion of the proposed circulation route for Cedar Creek II. Some 30% of the Cedar Creek II circulation route will overlap the existing missile routes. Consequently, activities and logistics should be coordinated with the DOD as appropriate. • 37 • IX. CONCLUSIONS Based upon the above documented investigations and analyses, the following can be concluded. • Area traffic conditions are very acceptable given the modest amount of traf- fic using SH 71 and the negligible traffic on County roads. • LOS "A" is currently being experienced at the CR 120 and CR 132 inter- sections with SH 71. • Offsite and onsite improvements will be made to accommodate large loads based on the findings of the BP, GE and B&K Trucking site survey. • Construction site traffic will be meaningful but manageable. It will range from 45 to 15 morning peak hour trips, 45 to 115 afternoon peak hour trips, and 140 to 510 daily trips during the approximate 10-month construction • period. • Site traffic after construction will be negligible, with up to 14 morning and afternoon peak-hour trips and 28 daily trips. • No auxiliary lane improvements are needed to serve Cedar Creek II traffic either during or after construction. Consequently, the existing roadway ge- ometry will serve future traffic demands through the long term. • All major intersections, namely the CR 120 and CR 132 intersections with SH 71, will operate very acceptably under all timeframes. This is docu- mented by the fact that all traffic movements at these intersections will op- erate at LOS "B" or better during all peak hours. • Temporary all-way stop sign control should be implemented at the CR 120—CR 135 intersection during construction. Alternately, a 40 MPH speed limit should be posted in both directions on CR 120 approaching CR 135 and a stop sign should be posted for southbound CR 135 traffic. Addi- • 38 tionally, a temporary stop sign and a westbound 45 MPH speed limit on CR 126 approaching CR 129 should be implemented. In lieu of the above spot speed restrictions, the County should reconsider its' earlier decision and al- low 40 MPH construction speed limits on all impacted roadways. This will enhance safety throughout the work area. Conditions could be returned to normal after construction. • Coordination with DOD may be appropriate when large loads arrive at the site. • Conflicts with school bus traffic will be minimal since the school bus only serves one house in this area. Furthermore, approximately one-half of the peak construction activity will occur when school is not in session. • Surface treating CR 132 from SH 71 to CR 135 and CR 135 from CR 132 to CR 130 with dust control agents should be considered during construc- tion to mitigate dust. Watering all other roadways as needed to mitigate dust should be sufficient. No dust treatment will be necessary after con- struction. • Cedar Creek II is viable from a traffic engineering perspective. In summary, with the indicated improvements, Cedar Creek II traffic will be fully mitigated. Acceptable operating conditions can be expected in this area for the fore- seeable future. • 39 X.

B&K will need to use the double radii as a swing wide to go east. The other option would be to install a cut-through prior to the hill. Both sides need temporary removable STOP signs for ease of entry. Junction with CR 120—Main return road for GE trucks (All in agreement) Need radii on north and south sides. Line of sight is very poor to the south. Most trucks will go north, however, some blade and nacelle trucks will have to go south. Also need temporary removable STOP sign. DELIVERY ROUTE CONSIDERATIONS • Intersection of CR 132 and CR 135 (by Construction & Laydown Yard) If land on southeast corner is a non-participant,there will need to be a radius to the north and a swing wide to head south. This will be a very busy intersection throughout the project. Temporary removable STOP sign. Intersection of CR 135 and CR 134 Not enough room to put in radius. Will either need to put in a cut-through farther north or continue string road to GE48 over to include GE49 and GE50. (All in agreement) CR 130 Road on map toward GE31 to GE35 does not exist. Can see the trail all covered in grass. String road will be new road. 90° turn-CR 130 and CR 131 Will need to shave down hill for radius. Dirt can be used to fill in on CR 131 side. CR 126—Crest rebuild First crest west of CR 131 will need to be built up about 1/16`h mile and about 2 feet to allow for clearance. Will possibly need to add a pole on the south side to ensure clearance of electri- cal lines to house. CR 128—Stabilization Road has many soft spots that will not hold up to heavy traffic. May want to stabilize to the last string road entrance. 4111 CR 126 west of CR 129 High water zone. Has signs posted and ground is much darker in the area. Need to watch very closely after heavy rains. May need additional consideration. Intersection of CR 127 and CR 124—Offset Check with landowner to see if it is possible to run a cut-through from CR 124 east straight to CR 124 west. With the contour of the land in the area it would be very difficult installing two separate radii. (All in agreement) THIS CONCLUDES THE DELIVERY ROUTE CONSIDERATIONS RETURN ROUTE CONSIDERATIONS 90° at CR 116 and CR 133 Add inside radius to ensure stacked trucks and double Schnabel trucks can maneuver around the turn. 90° at CR 133 and CR 120 Add outside swing wide (approx. 3 feet)to ensure stacked trucks and double Schnabel trucks can maneuver around the turn. CR 120 Just after the turn above there is a flash flood waterway. Will need to keep a close eye on this area after any rain in the area. Junction of CR 120 and CR 135 Add swing wide on west side of CR 135 to ensure stacked trucks and double Schnabel trucks can maneuver around the turn and get straight to get through cattle guard. CR 135 There is one major waterway and three minor waterways along this road that will need to be monitored after any rain in the area.

Copies of the proposed emergency response plans were presented to Daniel Harms for his review and we will provide copies of the final plans when they are complete. The action items from the meeting are: - Provide a project map with grid coordinates to Pawnee Fire. We will provide enough copies of the plan to place a copy in each of the Pawnee Fire vehicle as well as 2 large maps to post in the Fire Department. The maps will have contact information for the points of contact for the project. - Provide a hand held radio to Pawnee Fire for coordination with Wind Farm Project personnel. - Invite Pawnee Fire to construction kick-off meeting. - Pawnee Fire personnel are First Responder trained but have no EMT or paramedics on staff. • - Pawnee Fire will be a backup to New Raymer for any issues on the project with the exception of the work within their coverage area. - Response time will be approximately 30 minutes. - We will need to get the direct dial phone number to emergency dispatch because we are not certain where calls to 911 will be routed. We also discussed the location of the closest Life Flight for the project and were informed that the nearest locations were Greely, CO and Scott's Bluff, NE. Greely is also a Trauma 1 hospital.

I am interested in the proposal to be heard tomorrow - case number USR-1723. I am specifically concerned about the transmission line that will cross T1ON R58W Section 4. I have visited several times with David Gonzales regarding his plan to cross land I regard as my property. The county records show me as owning the rectangular north half of the SE corner of Section 4 of T10N, R58W and therefore not the owner of the land to be crossed. My property is, however, by history, usage, fence lines, and recognition by surrounding property owners as an irregular shape further to the southeast. Is tomorrow's (Tuesday, May 18) planning meeting the best forum to express my concerns? I believe it is to be heard at 1:30 in the Weld County Planning Department Hearing Room, 918 10th St. in Greeley. Can you confirm that time and location and that this would be the proper forum in which to say something? I also understand that the matter comes before the County Commissioners at 1:30 on Wednesday. It would be my hope that the County Commissioners table this matter until resolution of this conflict has been obtained.

We do support this project without reservation. We sent the following to be read into the record during the March • 16th hearing and are requesting that it be added to the minutes of the next meetings and hearings. With our thanks... To: The Weld County Department of Planning Services: Please read the following statement into the official record of comments given by landowners regarding The Cedar Creek Wind Farm Phase II: At its essence, our story is no different than those of our neighboring landowners. Each of us has our history of triumph and tragedy. All of us have endured flood and drought, high yields and low market prices; disasters both natural and man made. As you review the opinions put forth regarding construction of Phase II of The Cedar Creek Wind Farm, every producer and landowner can and likely will tell you that this renewable energy project will add stability to an uncertain agriculture economy. At full operational strength, land use and its value will inevitably increase in a reliable and measurable rate. It will establish a new sense of economic security that is, at the moment, diminishing on the family farm. During our 50 plus years as owners and producers, we have taken great pride with each harvest that our efforts, along the hard work and cooperation of so many others, have provided employment and a steady food source for this nation. Our cooperation with the United States Department of Defense illustrates an additional commitment we've made • by yielding a portion of our property for the purpose of national security. And of great importance, we must note that we've worked closely with British Petroleum since the early stages of the Phase II planning process and believe that they are operating in the best interest of the owners and 1 producers, the various environmental groups and the adjacent existing enterprises as they fulfill their obligations • to bring this vital energy resource online. With a clear sense history along with our unflagging dedication to uphold the legacy left by previous generations, we look to the future and stand behind this project and encourage all levels of Weld County government to do so, as well.
