If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. PLANNING QUESTIONS: Planner on Call (970) 353-6100 x3540 1. Explain, in detail, the proposed use of the property. The solar array project will deliver electrical energy to United Power under a 20 -year power purchase agreement (PPA) and must commence commercial operation no later than July 31, 2017. The project is designed for un-manned operation except for quarterly inspections and routine maintenance. As such, this facility will not represent any significant traffic impacts to the adjacent county roads and the region following the construction phase. The solar array facility will be located on a parcel of land that is approximately 320 acres in area, and the footprint of the solar array will comprise of approximately 242 acres of land. Of this 242 acres, approximately 40% of that area will remain open space. The solar modules will be mounted on single -axis tracking structures, which are designed to follow the sun's E -W path throughout the day. The modules will be mounted approximately five feet above grade with inverter stations positioned within the array field interior to the project site, these inverters stand approximately 8' in height. The solar array panel will be a maximum of±8' above grade with the modules at full - tilt. No significant visual impacts or glare are anticipated for adjacent or nearby properties or roadways. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. Section 22-2-70 of the Weld County Code describes the intent of the industrial goals is to establish industrial areas where a balanced, diversified economy can be encouraged in an effort to maintain and enhance the quality of life of Weld County citizens. These Goals and Policies intend to assure desirable local employment opportunities and to strengthen and stabilize the economy. Section 22-4-40 of the Weld County Code describes allowing development that encourage clean air and emissions of hazardous pollutants. This development uses solar power and converts it to electrical power. This development will not discharge any air emissions into the atmosphere or cause any dust or odor. LAMP RYNEARSON COMPANIES LAMP RYNEARSON 1 ZA Water Engineers Jl LARKING LAMP RYNEARSON _� LARK] Aaunncs Section 22-4-60 of the Weld County Code describes how noise shall be considered. This development will not generate any perceivable noise and therefore complies with this development requirement. Section 22-4-80 of the Weld County Code describes how waste shall be considered. This development will not generate regular waste by from production of electrical energy and therefore complies with this development requirement. Section 22-5-110 and 22-5-120 NR Goal 5 of the Weld County Code describes that other natural resources shall be utilized. The proposed solar array is a renewable natural resources that would be supportable by these sections and code requirements. Section 22-5-130 of the Weld County Code specifically describes that Weld County supports and encourages the use of Alternative Energy Recourses. Weld County does not intend to replace traditional sources of energy, but supports the expanding of the "New Energy Economy" to support and enhance traditional sources of energy. This development is considered an Alternative Energy Resource and shall be supported by Weld County. Section 22-5-140, AE Goal 1 (5).b of the Weld County Code specifically encourages large-scale commercial solar collection for energy support facilities. This solar facility is a commercial sized facility and utilizes the scale of economies to produce electrical power to the citizens of Weld County for economic sustainability. 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. Section 23-3-330 of the Weld County Code describes the Uses that can be developed in the 1-3 zone district. Within this zone district there is a list of developments that are allowed by a Use by Right and with the Use By Special Review process, however it does not specifically mention solar facilities. In discussions with Weld County Planning staff it has be decided to process this application through a Use By Special Review. Within the 1-3 Zone District there are other uses that are similar in description such as; Major Facilities of Public Utilities or more intense uses such as; Heavy Manufacturing, Commercial Junk Yards and Salvage Yards, therefore the Use By Special Review is an appropriate review process. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The property surrounding this site is a mix of agricultural, Oil/Gas wells and infrastructure, irrigation center pivots, tire recycling center and an outdoor storage and/or salvage yard. As described above, this site is fully contained and will not hinder the production, or landscape, of its surrounding neighbors. This proposed development is located in zone district 1-3. The adjacent property to the north, west and south is zoned A, and the adjacent property to the east is zoned 1-3. Adjacent to the site there are limited residential housing, and more so developed with Oil and Gas production facilities. 5. What are the hours and days of operation? (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.) 24/7, 365 days a year, 24 hours a day. 6. List the number of full time and/or part time employees to work at this site. During construction it is anticipated that there will be a maximum of 100 employees and contractors onsite during the peak construction phase. Post construction the facility will be un-manned and only periodic site visits will be performed. 7. If shift work is proposed, include the number of employees per shift. Not applicable. This is an un-manned facility. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. During construction there will be the construction crew. The construction crew consists of the project managers, laborers with pile driving equipment, electricians, civil contractors with earth moving equipment. Once construction is complete, then the site will likely be visited on a quarterly basis, generally in a light duty pickup truck during typical business hours. During these site visits the work to be completed will generally be for general array and site maintenance. There will be no regular deliveries, customers, volunteers, etc. post construction. For daily security the site is monitored remotely. A security fence will be installed surrounding the property and therefore enclosing the solar array facility. For general maintenance the site will be visited quarterly for inspection and general maintenance items. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. Not applicable. No animals will be onsite. 10. Describe the type if lot surface and the square footage of each type. (e.g. asphalt, gravel, landscape, landscape, dirt, grass, buildings). For the construction of the solar array it is expected that a portion of the parcel will need to be graded to create a smooth flat surface to aid in the construction of the solararray. These grading activities shall be completed in limited areas and will be minimized as much as possible to reduce land disturbance. Once the land is graded, then a low growth seed mix will be planted in the disturbed areas and revegetated, therefore the entire site will ultimately remain native grasses. Negligible impervious area will added to the site. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? Not Applicable. Since this site is un-manned, no parking stalls are proposed. 12. Explain the existing and proposed landscaping for the site. The existing landscape for the site is a sage brush and native grasses. The vegetation is not very dense and the under laying soil is a well -draining sandy soil. The proposed landscaping for this site will be to re -seed any disturbed areas with a native low growth seed mix that will be selected by a qualified horticulturist. It is expected that there will be minimal buffering requirement and this will be limited to the north of the site along CR 28. Along the north side of the property, it is proposed to plant hardy shrubs to help break up the visual of the fence. There are very little trees in the area and therefore additional trees are not proposed with this project. Irrigation to any planted shrubs is not proposed at this time. Grass will be mowed on an "as needed" basis. Landscaping will be minimal and will be keep in a suitable condition for the area and to support the operation of the solar facility. 13. Describe the type of fence proposed for the site (e.g. 6 foot chain link with earth tone slats) The proposed fence to be installed is a 6.0 foot high galvanized fence with 3 strand barb wire on top. 14. Describe the proposed screening for all parking and outdoor storage areas. As mentioned above, the only place where screening is proposed is on the north side of the project along CR 28. The landscape proposed is limited to shrubs as there are very sparse native trees in the area. Since very few trees are visible from this site, trees are not being proposed as a landscape improvement. The landscape being selected shall blend with the surround vegetation. A parking lot or outdoor storage is not proposed with this project and therefore screening these improvements are not applicable. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Upon the termination of the Power Purchase Agreement (PPA), Silicon Ranch will remove all improvements and either recycle, reuse, or repurpose the materials. The contours of the land will be smoothed as needed and any disturbed land will be reseeded with a native dryland seed mixture and allowed to re-establish to blend in to the surrounding landscaping. A decommissioning plan has been provided for your information. 16. Who will provide fire protection to the site? Fire protection will be provided by Platteville-Gilcrest Fire Rescue, located at 303 Main Street, Platteville, CO 80651 (Platteville Station #1), and 14679 WCR 42, Platteville CO 80651 (Gilcrest Station #2). 17. List all proposed on -site and off -site improvements and associated with the use (e.g. landscaping, fencing, buildings, drainage, turn lanes, etc.) and a timeline of when you will have each one of the improvements completed. Proposed improvements generally include the following: 1. BMP's 2. Grading 3. Drainage facilities 4. Support Piles 5. Fencing 6. Install solar panels 7. Install inverter pads and place inverters 8. Interconnect and associated offsite power lines 9. Landscaping / seeding Commercial Operation and facility completion by: 15 days 30 days 15 days 60 to 120 days 30 days 60 to 120 days 15 to 30 days each 30 days 15 to 60 days June 30, 2017 ENGINEERING QUESTIONS: Engineer on Call (970) 353-6100 x3540 1. Describe how many roundtrips/day are expected for each vehicle type: Passenger Cars/Pickups, Tandem Trucks, Semi-Truck/Trailer/RV (Roundtrip = 1 trip in and 1 trip out of site) Construction Phase (0 to 9 months): During construction it is anticipated that traffic will generally include semi -trucks and trailers (WB- 50) along with rental cars and light duty pickup trucks. During the construction phase the following trip ends are estimated as following: • Semi -trucks: 20 trip ends per day - 10 deliveries @ 2 trip ends per day • Employee and sub -contractor vehicles: 100 trip ends per day at peak construction. - 50 vehicles @ 2 trip ends per day (contractors and labors generally stay on site for lunch) Peak trip will be in the AM and contractor trips are expected throughout the day. Post Construction (9 months to 20+ years): The facility is designed for unmanned operation. Once in commercial operation the site will only require quarterly inspections and periodic maintenance. Site visits are expected to be during scheduled daylight hours. Vehicles accessing the site will be small rental cars or a light -duty pickup truck. Once the site is constructed, traffic generated by this site will not have a noticeable increase in traffic to Weld County Road 28 or to the surrounding area. • Light duty pickup trucks: ±10 trip ends per year - 4 quarterly site visits - 2 maintenance trips 2. Describe the expected travel routes for site traffic. It is expected that the majority of the traffic will be traveling on Hwy 85, then east on CR 32, South on CR 39, then east on CR28 to the solar facility. It is not anticipated that much traffic will come from the east. 3. Describe the travel distribution along the routes (e.g. 50% of traffic will come from the north, 20% from the south, 30% from the east, etc.) Traffic distribution is expected to be 95% from Hwy 85 as described above and less than 5% from the east. 4. Describe the time of day that you expect the highest traffic volumes from above. During construction it is anticipated that the delivery traffic will access the site throughout the day. Employee and contractor traffic will arrive around 7:00 am and will leave around 7:00 pm. Post construction, it is anticipated that any site visits will be performed during normal business hours. 5. Describe where the access to the site is planned. It is expected that the main entrance to the solar facility will be from CR 28 approx. 600 feet east of the intersection of CR 28 ad CR 39. There will also, be gates installed along the west side of the property to access the privately maintained road on the west property line, this is the extension of CR 39. No access points are proposed on the east or south side of the solar facility due to no existing roadways. 6. Drainage Design: Detention pond summarized in a drainage report is required unless the project falls under an exception to stormwater detention requirements per code section 23-12-30 F.1. A. Does your site qualify for an exception to stormwater detention? If so, describe in a drainage narrative the following: See attached Drainage Narrative for answers to the following questions. 1. Which exception is being applied for and include supporting documentation. 2. Where the water originates if it flows onto the property from an offsite source 3. Where it flows to as it leaves the property 4. The direction of flow across the property 5. If there have been previous drainage problems with the property B. Does your site require a stormwater detention pond? If so, the following applies: 1. A drainage report summarizing the detention pond design with construction drawings and maintenance plan shall be completed by a Colorado Licensed Professional Engineer and adhere to the drainage related sections of the Weld County Code. 2. The drainage report must include a certification of compliance stamped and signed by the PE which can be found on the engineering website. 3. A general drainage report guidance checklist is available on the engineering website. More complete checklists are available upon request. ENVIRONMENTAL HEALTH QUESTIONS: (970) 304-6415 x2702 1. What is the drinking water source on the property? If utilizing a drinking water well include either the well permit or well permit application that was submitted to the State -Division of Water Resources. If utilizing a public water tap include a letter from the Water District, a tap or meter number, or a copy of the water bill. Since this an un-manned facility, a domestic water tap is not needed with this development. During construction bottled water will be available to workers. Low growing, dry land grass will be planted and irrigation water will be hauled in "as needed" from a local water service provider or other means available. Once the dryland grass is established then there will not be a need for permanent irrigation. During construction water will be hauled in by a local water service provider or a water tap from Central Weld Water to control dust and erosion. From a site visit, it appears that Central Weld has a water main in CR 28. 2. What type of sewage disposal system is on the property? If utilizing an existing septic system provide the septic permit number. If there is no septic permit due to the age of the existing septic system, apply for a septic permit through the Department of Public Health and Environment prior to submitting this application. If a new septic system will be installed please state "a new septic system is proposed". Only propose portable toilets if the use is consistent with the Department of Public Health and Environment's portable toilet policy. Port -A -Potty or other temporary sanitary sewer facilities will be provided during construction. Once constructed, this will be an un-manned facility and therefore a sanitary sewer service is not needed with this development. 3. If storage or warehousing is proposed, what type of items will be stored? It is proposed to keep on -site basic repair materials and general maintenance items. All items will be contained an enclosed sea -can and will be locked. No oils or hydrocarbons will be stored in large quantities. If hydrocarbons are stored in the sea -can, then they will be stored in the manufactures provided containers and in quantities less than 5 gallons. 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. During construction all trash generated will be placed in an approved trash or recyclable receptacle and will be hauled away and properly disposed or recycled. Once construction is completed, all trash generated during scheduled site visits will be removed from the site on that site visit. Since this is an un-manned facility, there is no need for regular trash service. There will be no storage or stock piling of wastes onsite. 5. If there will be fuel storage on site indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. All fuel will be hauled in on an "as needed" basis. It is not anticipated that fuel will be stored on site during or post construction. 6. If there will be washing of vehicles or equipment on site indicate how the wash water will be contained. Not applicable. No vehicle or other washing facilities are proposed. 7. If there will be floor drains indicate how the fluids will be contained. Not applicable. No structures are proposed. 8. Indicate if there will be any air emissions. (e.g. painting, oil storage, etc.) Not applicable. Once the facility is constructed this will be an un-manned facility and therefore the only air emissions that would occur would be during basic site maintenance operations and will be in very small quantities. 9. Provide a design and operations plan if applicable. (e.g. composting, landfills, etc.) Not applicable. This will be an un-manned facility and the daily operation will be the solar array rotating throughout the day. Electrical power will be generated and conducted to the United Power Substation. 10. Provide a nuisance management plan if applicable. (e.g. dairies, feedlots, etc.) Not applicable. This facility will not generate any nuisances to the surrounding properties. 11. Additional information may be requested depending on type of land use requested. Acknowledged. BUILDING QUESTIONS: Jose Gonzalez (970) 353-6100 1. List the type, size (square footage), and number of existing and proposed structures. Show and label all existing and proposed structures on the USR drawing. Label the use of the building and the square footage. No permanent structures are proposed with this development. The Solar array will be un-manned and therefore no permanent buildings are needed for the daily operations. There may be one (1) conex brought onsite to store maintenance material and basic repair parts. The conex will be enclosed to provide security and protection to the stored material from the natural elements. 2. Explain how the existing structures will be used for this USR? Not applicable. All existing structures will be demolished to allow for the construction of the solar facility. 3. List the proposed use(s) of each structure. Not applicable, all existing structures will be removed and no new structures are proposed.

Colorado 80525 IF] 970.225.0342 IF] 970.225.0879 Supplemental Questions for Rattlesnake USR Application 8. Provide written responses to the following supplemental questions for solar arrays: A. The Planning Commission and Board of County Commissioners shall consider the following criteria in making their determination in approving or denying a Special Review Permit for a Solar Facility in addition to those criteria enumerated in Chapter 23, Article II, Division 4 and its impact on prime agricultural land which is defined as soils with agricultural capability classifications of I, II and III as indicated on maps completed by the U.S.D.A. Natural Resource Service. a. Not Applicable. Per the USDA Web Survey Map the land within the project boundaries is situated in a land classification of 4 and 6 for non -irrigated crop land farming. If the land were to be irrigated then only 17.4% of the entire site would be situated in a land classification of 3. Since this land has not been irrigated or historically used for farming the impact to the agriculture production is zero (0) and therefore land classification shall not be used as a consideration for approval or denial and does not apply as this land is not "Prime Agriculture" land. B. A Decommissioning Plan. Adequate financial assurance to cover the decommissioning of the facility may be required as a condition of approval of the Decommissioning Plan. a. See attached UP Decommissioning plan. C. Landscaping is extremely important for enhancing the quality of development in the area. Trees, shrubs and other plantings add greatly to the aesthetic appeal while reducing glare. As no single landscaping plan can be prescribed for all developments due to differing land features, topography and soils, these guidelines encourage flexible and creative landscape designs. Landscaping/screening shall include, at a minimum, decorative fencing, berming, and/or vegetation such that the facility is aesthetically pleasing as viewed from adjacent properties and rights -of -way. a. The landscape design for this development will match the surrounding industrial areas. The fence shall be a 6' galvanized chain -link fence with 3 stranded barb wire on the top. Due to the land classification of 4 and 6 there are very little visible trees and predominately populated with sage brush and sparse dryland grasses. The surrounding neighboring properties consist of primarily oil and gas facilities, large industrial uses, such as a tire recycling and outdoor storage, and therefore are uninhabited. Due to the industrial feel of the area limited residential dwellings LAMP RYNEARSON COMPANIES 1 ZA Water Engineers Jl _� LARK] AQUATICS LAMP RYNEARS0N LARKING LAMP RYNEARSON exist. Because of the feel of the area and poor soils, the vegetation being proposed will be dryland grass. b. It is not anticipated that this land will see substantial development in the next 20 years and during the decommissioning phase the fence will be removed. Due to the limited future development and removal of facility, the proposed fence shall be galvanized and no trees and shrubs will be planted. D. All reasonable alternatives to the proposed location have been adequately assessed, and the proposed action is consistent with the best interests of the people of the County and represents a balanced use of resources in the affected area. a. This project will provide energy to the residents and businesses of Weld County. This site was selected following an exhaustive search of property which to align the discreet set of technical design and geographic criteria and best serve the needs of these energy consumers. Due to the zoning classification and prevalent industrial activity in the region and on adjacent sites, this site is ideally suited for a project of this scale to serve the interests of Weld County residents. E. The nature and location or expansion of the facility will not unreasonably interfere with any irrigation systems on or adjacent to the solar facility. a. Not applicable. The land to be developed is non -irrigated dryland ground. There are no irrigation lines or ditches on -site that need to be maintained. Adjacent properties appear to have center pivots and the water source is believed to be by wells situated on the adjacent properties. F. No outdoor storage of any materials and equipment, including but not limited to solar panels and support structures which are not in use, will be allowed. a. No permanent outdoor storage will be proposed with this development. All material or equipment will be brought to the site and removed during each visit. G. A Property Maintenance Plan is required for the facility. The Property Maintenance Plan shall address dust, weeds and erosion. The property shall be maintained in such a manner as to control dust, weeds and drainage that could cause erosion. a. A long-term operations and maintenance plan for the project will be put in place, which includes maintenance of the grounds. The standard practice is to seed the property with native, low growth grasses to prevent shading of the array and minimize maintenance. b. Mowing and trimming operations will occur annually, or as needed to prevent the site from looking unmaintained. / Loren Snyder WO WCR 28, LLC 510 East 51" Avenue #205 Denver, CO 80216 April 22, 2016 To Whom It May Concern: WO WCR 28, LLC authorizes Silicon Ranch Corporation to conduct land use planning, permitting, engineering and regulatory work relating to the Weld County Land Use Permitting on the property known as 19028 County Road 28 Platteville, CO 80651.

The proposed development is located in the west 1/2 of Section 32, Township 3 north, Range 65 west. More specifically the project site is approximately 320 acres of land and is located approximately 0.25 miles east of the intersection of Weld County Road 39 and Weld County Road 28. The site is approximately 7.0 miles southeast of Platteville. The facility proposed as a photovoltaic solar facility that will provide electrical power to the United Power electric grid system. Electrical power generated by this facility will provide a renewable energy resource to United Power's portfolio. The facility will be owned and operated by Silicon Ranch Corporation under a 20 year Power Purchase Agreement. Site access will be a full movement from Weld County Road 28. An access permit application for this development is included as part of the submittal. During construction (6 to 9 months) During construction it is anticipated that traffic will generally include semi -trucks and trailers (WB- 50) along with rental cars and light duty pickup trucks. During the construction phase the following trip ends are estimated: • Semi -trucks: 20 trip ends per day - 10 deliveries @ 2 trip ends per day • Employee and sub -contractor vehicles: 100 trip ends per day at peak construction. - 50 vehicles @ 2 trip ends per day (employees tend to stay on site during construction and will carpool so this estimate is considered conservative) JIL LAMP RYNEARSON LAMP RYNEARSON COMPANIES TZA water En...—. 9IL LARKIN LAMP RYNEARSON AJUATICS Peak trip traffic will be in the AM and contractor trips are expected to occur throughout the day. Post Construction (9 months to 20+ years): The facility is designed for unmanned operation. Once in commercial operation the site will only require bi-annual inspections and periodic maintenance. Site visits are expected to be during scheduled daylight hours. Vehicles accessing the site will be rental cars or a typical pickup truck. Once the site is constructed, traffic generated by this site will not have a noticeable increase in traffic to Weld County Road 39 or to the surrounding area. • Typical pickup trucks: ±8 trip ends per year - 4 quarterly visits for inspections and mowing - 2 maintenance trips Traffic Distribution: It is anticipated that vehicular distribution will be from WCR 28 in to the site.

Troy Spraker, 4E Project Mana April 22, 2016 Mr. Wayne Howard Weld County Engineering Department 1555 North 17th Avenue Greeley, Colorado 80631 RE: Stormwater Detention Waiver Request for Silicon Ranch — Rattlesnake Solar Array Project Weld County, CO LRA Project No. 0216014.00 USR16-00 Dear Mr. Howard: LAMP RYNEARSON & ASSOCIATES ENGINEERS I SURVEYORS 1 PLANNERS 4715 Innovation Drive, Suite 100 Fort Collins, Colorado 80525 [P] 970.226 0342 IF] 970 226.0879 www.LRA-Inc corn Lamp, Rynearson & Associates, Inc. (LRA) is submitting this request (on behalf of Silicon Ranch Co., the owner) for a stormwater detention waiver for the Silicon Ranch — Rattlesnake Solar Array Project located in Weld County, Colorado. Project details and specific stormwater detention waiver request information are provided below. Project Site The proposed development is located in the western 1/2 of Section 32, Township 3 north, Range 65 west. The project is approximately 320 acres in area and situated at the southeast corner of the intersection of WCR 39 and WCR 28. The site is roughly 7 miles southeast of Platteville, Colorado. General Description of Proiect It is proposed that solar arrays be installed on the property through several phases of construction. The solar arrays will deliver renewable energy to United Power under a 20 -year power purchase agreement (PPA). Upon termination of the PPA, the solar panels will be removed and the land restored to historic conditions. Drainage Design Of the 317.9 acres of six parcels being developed, approximately 40% of that area will remain open space as exposed to the sky. Underneath the panels vegetation will be allowed to grow; therefore, it has been calculated that very little additional imperviousness is added to the site from the proposed improvements. Consequently, a waiver is requested to allow the site to sheet flow and be exempt from the requirement of providing water quality and detention ponds. Stormwater will surface flow in the general historic routing to the proposed drainage channels and collected in the proposed level spreaders / energy dissipaters and ultimately allowed to flow into the WCR 28 roadside ditch at the northeast corner of the site and adjacent property near the southeast corner of the site. Leaving a Legacy of Enduring Improvements to Our Communities - PURPOSE STATEMENT ENGINEERS SURVEYORS PLANNERS Detention Pond Exception Request With the development of this site, vegetation will be allowed to grow underneath the solar panels; therefore, it has been calculated that no imperviousness is added to the site due to the proposed improvements. As a result, a waiver is requested to allow the site to sheet flow in historic flow conditions and no detention pond required. The waiver being requested is Exception 1.A.8, which states: 1. Exceptions to stormwater detention shall not jeopardize the public health, safety, and welfare of public and private property and shall be limited to the following: A. No stormwater detention will be required for sites that meet any of the following conditions. Requirements of the Municipal Separate Storm Sewer System (MS4) areas remain applicable. 8. Development of sites where the change of use does not increase the imperviousness of the site. With the acceptance of this waiver request, Weld County will not require stormwater detention or water quality ponds. Upon future development or re -development of the site, the drainage design will be required to be investigated to determine future drainage needs. With the proposed design, stormwater will surface sheet flow and will be conveyed into the current offsite drainage conveyances in historic volumes and rates. Drainage Patterns Per the USGS contour data it appears that there is approximately 3000 acres of land that could potentially flow through this proposed development. Per a site visit there are no visible major drainage flow paths. The soil at the site appears to be very sandy with a very high infiltration rate. Although there is a large area that contributes to the proposed development it does not appear that much runoff ever is routed through the site. At the location of the roadside ditches it looks like the culverts that cross the access roads are 18 inches in diameter. Overall it looks like stormwater runoff is generated from the west and travels northeast through the proposed development and conveyed to the northeast corner of the site and discharged to the roadside ditch in CR 28. It should be noted in the northeast corner of the site there exists an oil and gas well and battery. At the access points for this oil and gas facility, there are no culverts, therefore this suggests that there is very little runoff is observed at this location. It does not appear that there are any drainage issues associated with this development or surrounding properties. Sediment and Erosion Control During construction, land grading activates will be minimized to allow for the installation of the solar arrays and BMPs will be installed where needed to minimize erosion and the transport of sediment offsite. Once the project is completed then any disturbed areas will be reseeded with a native low growth dryland seed mix. Once vegetation is considered established, then BMPs will be removed. The established vegetation will provide permanent water quality and sediment & erosion control for the site. If it is found that additional erosion control measures are needed after the site has been completed, then additional erosion and sediment control practices will be implemented. Conclusions Overall stormwater runoff will be allowed to sheet flow generally consistent with historic conditions. The proposed site improvements will generally result in no change to imperviousness, peak runoff rates, patterns or volume that would be observed offsite. This development will not cause additional health or safety risks to neighboring properties. If you have any questions or concerns, please feel free to contact me at your convenience.

Decommissioning Project Schedule 6 Attachment A Project Decomissioning Schedule B First Solar Module Recycling Process October 20, 2015 UP Solar Project SILICON RANCH Facility Decommissioning Plan 1. Introduction 1.1. Background As a condition of approval of the Use By Special Review County required Silicon Ranch Corporation to submit a Decommissioning Plan for the United Power Solar facility to the Department of Planning Services for review and approval. The Decommissioning Plan is required to include a detailed plan with time frames or milestones after termination of operations for restoring the property to the conditions that existed prior to the plant construction. The useful life of the solar plant is expected to be 25 years or more. At the end of useful life, Silicon Ranch Corporation will suspend operations and decommission the plant including necessary demolition and site reclamation. 1.2. Plan Purpose The purpose of this document is to establish a detailed plan for decommissioning and reclamation activities after the usefull life of the project has ended. Refinement of these activities will be required to reflect the future best practices or improvements are discovered by the solar industry during the life of the project. It will be necessary to update and finalize this demolition and reclamation plan. In addition to the detailed plan, a general schedule for the performance of the decommissioning with specific milestones is provided as Attachment A. We have assumed that the planning process would be initiated one or two years prior to the anticipated end of commercial operation. The final plans will be developed in consultation with the Weld County and/or other applicable agencies that have jurisdiction of activities in the decommissioning process. 2. Decommissioning Project Elements and Milestones The key tasks of the project are divided into related activities that represent milestones in the process. We describe the activies in each of the tasks in more detail below. The decommissioning schedule presents the conceptual timing of the milestones and overall process. The key Project components to be affected by decommissioning activities are discussed below. In general, decommissioning would attempt to maximize the recycling of all facility components. Specific opportunities for recycling are discussed below in the context of various site components. The individual Project components to be decommissioned will be recycled to the maximum extent practicable or removed from the site and disposed of at an appropriately October 20, 2015 2 UP Solar Project SILICON RANCH Facility Decommissioning Plan licensed disposal facility. The general decommissioning approach would be the same whether a portion of the Project or the entire Project would be decommissioned. 2.1. Planning The activities involved in the facility closure will depend on the expected future use of the site. Certain facility equipment and features may be left in place for future uses, such as transmission facilities, roads, and drainage features. At the time of decommissioning, a plan will be submitted to the County proposing the equipment that will be removed and, if applicable, equipment that will remain, based on expected future use of the site. Pre -closure activities, include final closure and reclamation planning, that identifies measures to be taken to restore the site to near pre -construction conditions or compatible with surrounding land and land use that may have evolved during the period the plant is in service. This includes several activities; • Set up and document a site -specific health and safety plan and determine the specific sequence and procedures to be followed. • Complete an analysis of the project materials and their composition to identify those specific components that may be recycled, scrapped, or sent to disposal sites. Identify specific recycling facilities and disposal sites for materials. • Coordinate with local officials to develop plans for the transportation of materials and equipment to and from the site. • Develop specifications for demolition and reclamation, which will serve as the basis for contractor bids for the decommissioning project and establish the scope of demolition and reclamation, including developing reclamation plans in compliance with local, state, and federal regulations. • Develop training for the personnel who will manage and perform the actual work. Document the performance or training. 2.2. Permitting During the planning process Silicon Ranch will brief the County and other applicable agencies on the decommissioning process and plans. The permits and approvals required for the decommissioning will be identified and permits will be obtained prior to commencing operations. October 20, 2015 3 UP Solar Project SILICON RANCH Facility Decommissioning Plan 2.3. Site Preparation for Decommissoning The first step in the decommissioning process would be to assess existing site conditions and prepare the site for demolition. Site decommissioning and equipment removal is expected to take a year. Therefore, access roads, fencing, some electrical power, and other facilities will temporarily remain in place for use by the decommissioning workers until no longer needed. Demolition debris will be placed in temporary onsite storage area(s) pending final transportation and disposal and/or recycling according to the procedures listed below. A plan for de -energizing portions of the facility to allow safe decommissioning and formal lock out and tag out procedures will be implemented. This will ensure all electrical components are placed and maintained in a safe condition for demolition activities prior start of work. 2.4. Disassembly and Demolition PV Module and Tracker Removal and Recycling During decommissioning, Project components that are no longer needed would be removed from the site and recycled or disposed of at an appropriately licensed disposal facility. The first operation is to disconnect and remove modules from the tracker assemblies. Modules are segregated for transportation to the manufacturer's nearest storage facility. Note: For the First Solar modules, a take back program is in place under which the module will be collected and recycled at the end of their useful life. Refer to Attachment B for details of the First Solar recycling process. Next comes the disassembly of the tracker and mounting structures, DC wiring materials, and combiner boxes. The material will be segregated for disposal or salvage. Steel piles that support the PV racking system will be removed. Below ground portions of the supports will either be removed or cut off at least two feet below ground surface and left in place. The demolition debris and removed equipment may be cut or dismantled into pieces that can be safely lifted or carried with the onsite equipment being used. The debris and equipment will be processed for transportation and delivery to an appropriately licensed disposal facility or recycling center. Modules will be recycled or disposed of in accordance with applicable laws at the time of decommissioning. Internal Power Collection System The combiner boxes that convey DC power generated from the solar arrays will be dismantled. The inverters that convert the DC power to AC power and the transformers that convert the output of the inverter and convey the power to the substation will also be dismantled and removed. The underground cable/collection lines that are 4 feet or shallower will be removed from the site. The cast -in -place concrete foundations of the transformer and inverter skids and switchgear. will be broken up, removed and recycled. October 20, 2015 4 UP Solar Project SILICON RANCH Facility Decommissioning Plan Any overhead portions of the collection system will be removed. Overhead conductors will be removed from the poles, and the poles and pole foundations will be removed. Aluminum from the conductors will be recycled or removed from the site to an appropriately licensed disposal facility. If not planned for other use, the utility interconnection will be deactivated and restored to the extent agreed upon with the local utility or to the point of change of ownership Medium voltage collector system electrical components will be electrically disconnected and made safe for removal. The switches will be disassembled and removed from the site. The underground conduit and metal dead-end structures will also be disassembled and removed. Concrete foundations for equipment will be broken up and removed from the site, as will the grounding grid and aggregate rock. Steel, aluminum, copper and other materials will be temporarily stockpiled at or near a designated processing location pending transport to an appropriate offsite recycling facility. All metals will be recycled to the extent practical given the recycling options available at the time of decommissioning. Roads Onsite access roads will remain in place to accomplish decommissioning at the end of the Project's life. At the time of decommissioning, if the roads will be beneficial for future use of the site; those roads may remain after decommissioning. Roads that will not be used will be restored during contouring operations at the end of the process. Fencing Project site perimeter fencing will be removed at the end of the decommissioning project, unless it may be utilized for future use of the site. Since the project site was not originally fenced, this includes removal of all posts, fencing material, gates etc. to return the site to pre -project condition. 2.5. Transportation and Clean up During the disassembly and demolition process materials are segregated and temporarily place in gathering areas for transportation. The various materials including concrete, steel, aluminum, copper and other materials will be temporarily stockpiled at or near a designated processing location pending transport to an appropriate offsite recycling facility. All such materials will be transported from the site to approved designated facilities for recycling, scrapping or disposal. All metals will be recycled to the extent practical given the recycling options available at the time of decommissioning. Modules will be collected and transported to storage sites for final recycling in accordance with the First Solar standard process for module recycling. Clean up of soils and site, if identified will be completed to ensure that clean closure is accomplished. October 20, 2015 5 UP Solar Project SILICON RANCH Facility Decommissioning Plan 2.6. Re -contouring and vegetation in general the decommissioning will be undertaken using traditional heavy construction equipment including but not limited to front end loaders, cranes, track mounted and rubber tired excavators, bull dozers, and scrapers. Where excavation is required those areas of removal will be backfilled with natural material and compacted. Any voids left from the removal of foundations will be backfilled with surrounding subsoil and topsoil and fine graded to ensure suitable drainage and reclamation of natural grades. Soil management and re -contouring operations will be conducted so as to minimize the surface area disturbance and implement the activities in the safest and most efficient manner and in accordance withal applicable local requirements. Major earthwork is not anticipated as construction of the site will not alter the general grade across the site. To provide for post -decommissioning dust control on the site, areas of exposed soils will be revegetated, consistent with the expected future use of the site. For example, future site use is expected to be agricultural, a revegetation approach will be implemented that will not conflict with the expect agricultural use. The native dry grass vegetation will be re-established to prevent the spread of weeds and long-term monitoring will be conducted to confirm reclamation and weed control are successful. Mulching or paliatives may be used for temporary dust control until vegetation is established. 2.7. Monitoring Site Restoration Upon completion of the decommissioning process a restoration monitoring period of one year will begin. Monitoring will ensure that grading and drainage implemented is successful in stabilizing water flow patterns and that the cover vegetation (native dry grass vegetation or other depending on land use) will be reestablished to prevent the spread of weeds. Corrective actions will be implemented if such monitoring determines adverse conditions are present as a result of an inadequate restoration. 2.8. Project Quality Control and Documentation During the entire decommissioning process, from planning to site monitoring, the project will be subject to quality control and documentation. Silicon Ranch will ensure the effective execution of the decommissioning and reclamation plan through project oversight and quality assurance. in addition we will document implementation of the plan and compliance with all applicable regulatory and environmental requirement. 3. Decommissioning Project Schedule A schedule for the performance of the decommissioning with specific milestones is provided as Attachment A. Refinement of these activities will be required to reflect the future best practices October 20, 2015 6 UP Solar Project SILICON RANCH Facility Decommissioning Plan or improvements are discovered by the solar industry during the life of the project. it will be necessary to update and finalize this demolition and reclamation plan and our proposed schedule. We have assumed that the planning process would be initiated one or two years prior to the anticipated end of commercial operation. Planning for the decommissioning activities and the associated permitting is scheduled far in advance to allow for meaningful consultation with the Weld County and/or other applicable agencies. Permitting will be finalized prior to the start of on site activities. The actual disassembly and decommissioning, followed by transporting materials offsite, and recontouring of the site, should require about a year, after which a monitoring process will continue for an additional year. The entire process will require as much as four years to complete.
