MACKENZIE MARIE MILLER NOTARY PUBLIC STATE OF COLORADO NOTARY ID 2022 4044820 lu'I'Y COMMISSION EXPIRES NOVEMBER 2$ 2026 My commission expires: 0, I 202'9 ''witness my hand and official seal: Use by Special Review - Solar Energy Facility Questionnaire Goldfinch Solar, LLC PID 080130400002 & 080130400003 1. Explain the proposed use and business name. Goldfinch Solar, LLC proposes a Solar Energy Facility (SEF) to be placed on Weld County PI D 080130400002 & 080130400003. The SEF will have a capacity of 7,000 kW AC and will cover approximately 34.5 acres on the west half portion of the total parcels. This SEF is constructed through Xcel Energy's Solar*Rewards Community Program. This program was implemented by the Colorado Public Utilities Commission in 2010 and mandates that Xcel work with independent, third -party solar developers to provide local energy production at the electric distribution level and provide ratepayers with the option to choose their energy source. This program combats potential full monopolization by Xcel in the generation and sale of energy to customers in Xcel territory. Furthermore, in order to win an award for our Goldfinch solar project, Goldfinch Solar, LLC had to compete against numerous other solar developers in a selective RFP process — a process which ultimately yields the best prices and quality of work for consumers. Goldfinch Solar, LLCs project will allow for a safe and well-timed addition of energy to the grid. Distributed energy projects like this have the added benefit of strengthening the local electric grid and creating a more resilient local electricity system. This project, and its relatively small footprint, will complement Weld County's numerous other energy generation industries and County's place as the energy capital of Colorado. The Goldfinch Solar, LLCs project will allow consumers to have a choice in their energy supply. With the construction of this project, Xcel customers in Weld County and all throughout the front range will have the ability to decide if they would like to subscribe to a portion of the solar array's output, thereby giving them 100% solar energy (an alternative to Xcel's one and only choice for consumers). 2. Explain the need for the proposed use. This project meets a multitude of needs in the community: The Landowner has water rights and historically is used to irrigate the parcel. However, the water they get is less and less every year and they must purchase water to finish out the crop to harvest. The market rates for purchasing water is wholly uneconomical as costs far exceed any possible return on investment. The addition of an SEF provides the opportunity for a long-term, predictable income stream while simultaneously fortifying the grid in Weld County. Rather than the parcel sitting as vacant rangeland, the construction of an SEF can provide local jobs and a long-term asset that will create energy at a competitive price to the benefit of Weld County residents. Residents in Xcel territory have not traditionally had a choice in who their utility provider is and where their energy comes from. Community solar solves this issue by providing ratepayers with an opportunity for choice, and an option to choose locally generated electricity. Weld County, and Colorado as a whole, is experiencing massive growth in electricity consumption. More electricity generation is needed to meet this need. Local solar projects like this help the state and county diversify its electricity sources and have local generation that result in a more stable and resilient grid. Weld County has long been the energy capital of Colorado and adding solar to the County will further diversify the County's energy mix and further its role as an energy leader in Colorado. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E Weld County's Comprehensive plan specifically calls out a goal of supporting "responsible energy and mineral development."This project meets the definition of responsible (see answer to question 21). 3. Describe the current and previous use of the land. The current and previous land use agriculture and currently has irrigated corn on it. 4. Describe the proximity of the proposed use to residences. There is one residence within 500 feet of the proposed SEF, which is to the SW of the facility at parcel # 080130400001. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. To the northeast at parcel no. 080123000046, and owned by Janice Marie Carson, is an existing solar facility. The rest of the surrounding parcels are all used for agricultural farmland and had oil and gas operations as well. From a health and safety perspective, solar is a compatible use for the surrounding lands. It produces no airborne or soil -leaching contaminants, making it safe for the nearby crops and any other agricultural production taking place. This addition will pose no health or safety threat to these uses. Solar is also one of the few uses for land that also contains active or abandoned oil and gas infrastructure. SEFs are not inhabited, and oil and gas contamination pose no threat to the solar array. Solar is a safe and non -disruptive use for this parcel; it is primed to be placed amidst an area with various uses. 6. Describe the hours and days of operation (i.e., Monday through Friday 8:00 a.m. to 5:00 Once construction is complete, the SEF will continuously operate 24/7, but only producing power during daylight hours. The proposed SEF will use single -axis trackers, which will angle the solar modules accordingly as the sun shifts in the sky. These trackers allow for maximized energy production. While the array will be running all day, it will create no disturbances. Solar arrays are nearly silent and produce no smoke, smog, vapors, or dust. Construction will run during normal business hours for the duration of about 3 months. 7. Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. During construction: Construction during daytime hours will range from 7 to 14 during the early mobilization and site preparation stage with site construction workers peaking at 50 to 60 workers midway through the project and reducing back down to 7 and 14 workers during the final commissioning and testing stage. Once operational: The SEF will have a maintenance crew visit once quarterly (or as needed if damage occurs due to weather), otherwise the SEF will be unmanned. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. N/A. This proposed use will be for energy production only and will not host patrons, etc. 9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock, confinement operations, kennels, etc.). Goldfinch Solar, LLC values the prominence of agriculture in Weld County, and we often make efforts to support the industry when constructing SEFs. One practice that we offer at our SEF is working with a local sheep rancher (with whom we have a pre-existing partnership), offering our site as grazing land for his sheep. This allows for the SEF site's vegetation to be maintained, while benefiting a local rancher (rather than employing mechanical mowers). We will have to complete a 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E more thorough analysis of the current vegetation of the area to determine if there is enough growth for the sheep. Should we move forward with sheep grazing, there will be approximately 60 sheep present onsite. The site will be fully fenced in, containing the sheep, and the rancher will have access to the site whenever needed. The sheep will visit for a few weeks at a time, as frequently as needed onsite. 10. List the types and number of operating and processing equipment. There will be an estimated total of 11,526 695w monocrystalline modules, 125kVA inverters, and rows of single -axis trackers. The system consists of string level DC to AC conversion inverters, main equipment pads with AC Recombiners, switchgear and MV step up transformers that connect to Xcers grid. 11. List the types, number and uses of the existing and proposed structures. There will be no structures associated with the proposed solar facility other than the solar array itself, which will be used for energy generation. 12. Describe the size of any stockpile, storage or waste areas. During the construction phase, there will be materials and equipment that may need a laydown yard located on the interior of the facility, see site sheet 9 of the USR plan (laydown area). When the construction is completed, there will be in place a metal conex container for storing spare modules and other spare parts. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. During the construction phase, waste will be stored in refuge dumpsters, which will be emptied on a regular basis or as needed. Once the facility is operational, there will be no waste or refuge produced from the solar operation. 14. Include a timetable showing the periods of time required for the construction of the operation. • Solar Facility Components First Deliver Day 1 • Perimeter Fence Installation Day 1 to Day 11 • Solar Panel Foundation Installation Day 1 to Day 30 • Racking, Trenching, Wiring Day 30 to Day 64 • Solar Panel Installation Day 64 to Day 94 • Inspection & Set Meters Day 94 to Day 99 • System Testing & Commissioning Day 99 to Day 109 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). The subject area (33.67 acres) is currently agricultural land and will need to be re -seeded within the construction area. Following the completion of the construction for each phase, disturbed areas within the limits of construction, such as roadcuts, utility trenches, and other areas where vegetation has been removed, altered, or eliminated, will be reseeded with native seed mix. There will be approximately 49,100 square feet of gravel area including the gravel access, gravel laydown, and the hammerhead turnaround. There will be one (1) concrete transformer pad of approximately 2000 square feet. 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? There will be two (2) temporary internal parking spaces for vehicles servicing the facility. There will be no ADA parking spaces, as this is not a facility for general public use. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur 5hpr COMWONITY 5 �?in.E 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. To comply with the National Electric Code, there will be an 8' tall game fence installed around the entire perimeter of the site. The fence and gate will be constructed of 4" X 4" welded rod material. The two (2) internal parking spaces on the site plan are temporary. There will be no outdoor storage associated with this proposed solar facility. 18. Describe the existing and proposed landscaping for the site. The entire area of the parcel is irrigated crop, usually silage corn. Once the construction phase is completed, the affected area within the solar facility fence will be seeded with a native seed mixture. A fence will be installed around the SW corner of the facility to screen the SEF from the nearby neighbor as fencing requires minimal maintenance and no additional water. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Once the site is no longer used for the proposed solar facility, the panels, racking, cabling, inverters, and all associated equipment will be removed from the site and recycled and/or disposed of in a responsible manner. The site will be returned to the condition it was in prior to the solar facility being constructed with the exception of certain site improvements desired by the landowner or system design such as re -grading, leveling, vegetation, and/or soil improvements. Solar leaves behind no ground contamination, so there will be no hazardous elements left behind on the land. 20. Describe the proposed fire protection measures. The subject property is within the Eaton Fire Protection District. Fire access within the facility will be via a 20' -wide gravel driveway, with a hammerhead or an acceptable hammerhead alternative turnaround at the end of the drive. Grasses within the solar facility will be mowed as needed, to help prevent the spread of range fires. Maintenance will be performed regularly each quarter, as well as on an as -needed basis, to monitor and maintain the electrical wiring of the system. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. The Weld County Comprehensive Plan addresses goals and objectives for natural resources (Weld County Code, Chapter 22, Sec.22-2-60). The proposed use of the subject property as a solar power generation facility is consistent with the goals and policies of this section. Section B states one goal of Weld County's is "Support responsible energy and mineral development." The County outlines the steps for this goal, and these following steps in particular, are supported by the SEF: "I. Ensure that surface development reasonably accommodates mineral extraction." Goldfinch Solar, LLC's SEFs work well when located near oil and gas activity as solar does not have to follow the same health and safety restrictions that inhabited buildings do. "3. Require that energy and mineral resource development conserve the land and minimize the impact on surrounding land and the existing surrounding land uses." The standard lifetime of an SEF is 20-40 years. At the end of its life, our SEF will be fully decommissioned, and the land that it stands atop will be fully restored. Additionally, this project should allow the land to go fallow for many years, improving the soil conditions for possible future agricultural use, should the landowner decide to change this parcel into an agriculture production instead of rangeland. Solar produces no contamination or noise pollution and will pose no threat to surrounding land uses. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -1§ur -1pr COMWONITY 5 �?in.E 41111 OP° 4litt1/4 "5. Energy development facilities should preserve agricultural areas and enhance the rural landscape." When decommissioned, the SEF will leave behind uncontaminated agricultural lands with renewed soil. During its lifetime, the solar array will have native vegetation growing beneath it, contributing to Weld County's vegetative health and supporting local pollinator communities. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) "Agriculture in the COUNTY is considered a valuable resource which must be protected from adverse impacts resulting from uncontrolled and undirected business, industrial and residential land USES. The A (Agricultural) Zone District was established to maintain and promote agriculture as an essential feature of the COUNTY. The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production, and for areas for natural resource extraction and energy development, without the interference of other, incompatible land USES." The subject property is zoned Agricultural (A). Solar Facilities are permitted as a Use by Special Review in the Agricultural zone district. The Use by Special Review process allows for adequate review by the Planning staff, Planning Commission, and the Board of County Commissioners, to ensure compatibility with surrounding land uses. Additionally, citizens are afforded adequate opportunities to express their concerns in the public hearing setting before any solar facility can be constructed on agriculturally- zoned land. Within the stated intent of the "Agricultural" Zone District is the specific reference to "natural resource extraction" and "energy development". This proposed solar power generation plant is in compliance with the intent of the "Agricultural" Zone District. Solar facilities allow farmers and ranchers another use for their land and a viable stream of income beyond traditional farming and ranching uses. The SEF does not permanently stand on the land, or contaminate it, allowing for the landowner should they decide to use this land for agricultural purposes after the 20-40 year SEF lifecycle. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. The subject parcel does fall within the Kersey CPA Intergovernmental Agreement Boundaries and per their response this project is not impactful to their master plans. Additionally, the proposed solar facility will be compatible with the remainder of the surrounding Area, which remains unincorporated. Much of the surrounding area is now, and will probably remain, agricultural in nature. In addition, oil/gas production will likely continue in the surrounding area. Solar development is very compatible with farming and ranching uses and oil/gas development. Renewable projects provide farmers and ranchers a viable alternate use to traditional farming and ranching uses on their land. Since there are no permanent structures being built as part of this proposal, the land can be returned to its agricultural use once the economic viability of the solar facility has ended. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. This development will positively impact the health, safety, and welfare of the inhabitants of the surrounding area and County. The SEF will create no airborne or ground contaminants, making it nonhazardous for residents near and far. The SEF is also nearly silent when operating, thus will not contribute to any noise pollution. The SEF will produce local electricity without adding any pollution to the air. The SEF will be fully fenced in with a security fence, making it inaccessible for trespassers and preventing potential hazardous situations. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -1§ur -1pr COMWONITY 5 �?in.E 41111 010 • • Goldfinch Solar, LLC will build the SEF according to both building codes and Xcel's standards and will pose no threat to the health and viability of the electric grid, locally or throughout the front range. The addition of solar energy to the grid will further diversify the energy mix supplied by Xcel, preventing dependence on any one source of fuel and eliminating the risks associated. The SEF will also provide Weld County residents (who are Xcel customers) with the opportunity to choose their energy source and energy provide, increasing consumer choices and economic freedom. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. While this land is zoned for agriculture, it should not be considered as prime farmland. The Weld County Code defines prime and non -prime farmland as follows: "FARMLAND - WELD COUNTY NONPRIME: NONPRIME FARMLAND is low capability land that is not considered important land for food production. It may be composed of poorer soils prone to erosion or may have topographical limitations such as slopes or gullies." "FARMLAND - WELD COUNTY PRIME: The availability of a consistent supply of quality water must exist in order to have PRIME FARMLANDS. PRIME and PRIME if irrigated lands fall into upper capability classes as defined by the Natural Resource Conservation Service and Colorado State University Cooperative Extension Service and should be protected equally if irrigation water is available and they are located within a reasonable distance of water delivery STRUCTURES." For the following reasons, Goldfinch Solar, LLC believes this parcel falls into the nonprime farmland category: 1) Due to the decrease of water every year, it will put an end to the landowner being able to farm the full area. The landowner currently must purchase water to finish the crops to harvest. Having the SEF on a portion of the land will then allow for the landowner to use the water they have without having to purchase more water. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. This location does not fall within any of the zoning districts. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. Goldfinch Solar, LLC will need to apply for the following permits to complete this SEF: County: Access Permit State: COR400000 Stormwater Discharge to be applied for and obtained following USR issuance Federal: N/A 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -'fur -1pr COMWONITY 5 �?in.E Use by Special Review - Solar Energy Facility Questionnaire Goldfinch Solar, LLC PID 080130400002 & 080130400003 1.

The market rates for purchasing water is wholly uneconomical as costs far exceed any possible return on investment. The addition of an SEF provides the opportunity for a long-term, predictable income stream while simultaneously fortifying the grid in Weld County. Rather than the parcel sitting as vacant rangeland, the construction of an SEF can provide local jobs and a long-term asset that will create energy at a competitive price to the benefit of Weld County residents. Residents in Xcel territory have not traditionally had a choice in who their utility provider is and where their energy comes from. Community solar solves this issue by providing ratepayers with an opportunity for choice, and an option to choose locally generated electricity. Weld County, and Colorado as a whole, is experiencing massive growth in electricity consumption. More electricity generation is needed to meet this need. Local solar projects like this help the state and county diversify its electricity sources and have local generation that result in a more stable and resilient grid. Weld County has long been the energy capital of Colorado and adding solar to the County will further diversify the County's energy mix and further its role as an energy leader in Colorado. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E Weld County's Comprehensive plan specifically calls out a goal of supporting "responsible energy and mineral development."This project meets the definition of responsible (see answer to question 21). 3. Describe the current and previous use of the land. The current and previous land use agriculture and currently has irrigated corn on it. 4. Describe the proximity of the proposed use to residences. There are no residence within 500 feet of the proposed SEF. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. To the northeast at parcel no. 080123000046, and owned by Janice Marie Carson, is an existing solar facility. The rest of the surrounding parcels are all used for agricultural farmland and had oil and gas operations as well. From a health and safety perspective, solar is a compatible use for the surrounding lands. It produces no airborne or soil -leaching contaminants, making it safe for the nearby crops and any other agricultural production taking place. This addition will pose no health or safety threat to these uses. Solar is also one of the few uses for land that also contains active or abandoned oil and gas infrastructure. SEFs are not inhabited, and oil and gas contamination pose no threat to the solar array. Solar is a safe and non -disruptive use for this parcel; it is primed to be placed amidst an area with various uses. 6. Describe the hours and days of operation (i.e., Monday through Friday 8:00 a.m. to 5:00 p.m.). Once construction is complete, the SEF will continuously operate 24/7, but only producing power during daylight hours. The proposed SEF will use single -axis trackers, which will angle the solar modules accordingly as the sun shifts in the sky. These trackers allow for maximized energy production. While the array will be running all day, it will create no disturbances. Solar arrays are nearly silent and produce no smoke, smog, vapors, or dust. Construction will run during normal business hours for the duration of about 3 months. 7. Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. During construction: Construction during daytime hours will range from 7 to 14 during the early mobilization and site preparation stage with site construction workers peaking at 50 to 60 workers midway through the project and reducing back down to 7 and 14 workers during the final commissioning and testing stage. Once operational: The SEF will have a maintenance crew visit once quarterly (or as needed if damage occurs due to weather), otherwise the SEF will be unmanned. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. N/A. This proposed use will be for energy production only and will not host patrons, etc. 9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock, confinement operations, kennels, etc.). Goldfinch Solar, LLC values the prominence of agriculture in Weld County, and we often make efforts to support the industry when constructing SEFs. One practice that we offer at our SEF is working with a local sheep rancher (with whom we have a pre-existing partnership), offering our site as grazing land for his sheep. This allows for the SEF site's vegetation to be maintained, while benefiting a local rancher (rather than employing mechanical mowers). We will have to complete a more thorough analysis of the current vegetation of the area to determine if there is enough 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E growth for the sheep. Should we move forward with sheep grazing, there will be approximately 60 sheep present onsite. The site will be fully fenced in, containing the sheep, and the rancher will have access to the site whenever needed. The sheep will visit for a few weeks at a time, as frequently as needed onsite. 10. List the types and number of operating and processing equipment. There will be an estimated total of 9,928 695w monocrystalline modules, 125kVA inverters, and rows of single -axis trackers. The system consists of string level DC to AC conversion inverters, main equipment pads with AC Recombiners, switchgear and MV step up transformers that connect t0 Xcel's grid. 11. List the types, number and uses of the existing and proposed structures. There will be no structures associated with the proposed solar facility other than the solar array itself, which will be used for energy generation. 12. Describe the size of any stockpile, storage or waste areas. During the construction phase, there will be materials and equipment that may need a laydown yard located on the interior of the facility, see site sheet 9 of the USR plan (laydown area). When the construction is completed, there will be in place a metal conex container for storing spare modules and other spare parts. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. During the construction phase, waste will be stored in refuge dumpsters, which will be emptied on a regular basis or as needed. Once the facility is operational, there will be no waste or refuge produced from the solar operation. 14. Include a timetable showing the periods of time required for the construction of the operation. • Solar Facility Components First Deliver Day 1 • Perimeter Fence Installation Day 1 to Day 11 • Solar Panel Foundation Installation Day 1 to Day 30 • Racking, Trenching, Wiring Day 30 to Day 64 • Solar Panel Installation Day 64 to Day 94 • Inspection & Set Meters Day 94 t0 Day 99 • System Testing & Commissioning Day 99 to Day 109 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). The subject area (29.31 acres) is currently agricultural land and will need to be re -seeded within the construction area. Following the completion of the construction for each phase, disturbed areas within the limits of construction, such as roadcuts, utility trenches, and other areas where vegetation has been removed, altered, or eliminated, will be reseeded with native seed mix. There will be approximately 49,100 square feet of gravel area including the gravel access, gravel laydown, and the hammerhead turnaround. There will be one (1) concrete transformer pad of approximately 2000 square feet. 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? There will be two (2) temporary internal parking spaces for vehicles servicing the facility. There will be no ADA parking spaces, as this is not a facility for general public use. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. To comply with the National Electric Code, there will be an 8' tall game fence installed around the entire perimeter of the site. The fence and gate will be constructed of 4" X 4" welded rod material. The two (2) internal parking spaces on the site plan are temporary. There will be no outdoor storage associated with this proposed solar facility. 18. Describe the existing and proposed landscaping for the site. The entire area of the parcel is irrigated crop, usually silage corn. Once the construction phase is completed, the affected area within the solar facility fence will be seeded with a native seed mixture. A fence will be installed around the SW corner of the facility to screen the SEF from the nearby neighbor as fencing requires minimal maintenance and no additional water. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Once the site is no longer used for the proposed solar facility, the panels, racking, cabling, inverters, and all associated equipment will be removed from the site and recycled and/or disposed of in a responsible manner. The site will be returned to the condition it was in prior to the solar facility being constructed with the exception of certain site improvements desired by the landowner or system design such as re -grading, leveling, vegetation, and/or soil improvements. Solar leaves behind no ground contamination, so there will be no hazardous elements left behind on the land. 20. Describe the proposed fire protection measures. The subject property is within the Eaton Fire Protection District. Fire access within the facility will be via a 20' -wide gravel driveway, with a hammerhead or an acceptable hammerhead alternative turnaround at the end of the drive. Grasses within the solar facility will be mowed as needed, to help prevent the spread of range fires. Maintenance will be performed regularly each quarter, as well as on an as -needed basis, to monitor and maintain the electrical wiring of the system. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. The Weld County Comprehensive Plan addresses goals and objectives for natural resources (Weld County Code, Chapter 22, Sec.22-2-60). The proposed use of the subject property as a solar power generation facility is consistent with the goals and policies of this section. Section B states one goal of Weld County's is "Support responsible energy and mineral development." The County outlines the steps for this goal, and these following steps in particular, are supported by the SEF: "I. Ensure that surface development reasonably accommodates mineral extraction." Goldfinch Solar, LLC's SEFs work well when located near oil and gas activity as solar does not have to follow the same health and safety restrictions that inhabited buildings do. "3. Require that energy and mineral resource development conserve the land and minimize the impact on surrounding land and the existing surrounding land uses." The standard lifetime of an SEF is 20-40 years. At the end of its life, our SEF will be fully decommissioned, and the land that it stands atop will be fully restored. Additionally, this project should allow the land to go fallow for many years, improving the soil conditions for possible future agricultural use, should the landowner decide to change this parcel into an agriculture production instead of rangeland. Solar produces no contamination or noise pollution and will pose no threat to surrounding land uses. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -1§ur -1pr COMWONITY 5 �?in.E 41111 OP° 4litt1/4 "5. Energy development facilities should preserve agricultural areas and enhance the rural landscape." When decommissioned, the SEF will leave behind uncontaminated agricultural lands with renewed soil. During its lifetime, the solar array will have native vegetation growing beneath it, contributing to Weld County's vegetative health and supporting local pollinator communities. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) "Agriculture in the COUNTY is considered a valuable resource which must be protected from adverse impacts resulting from uncontrolled and undirected business, industrial and residential land USES. The A (Agricultural) Zone District was established to maintain and promote agriculture as an essential feature of the COUNTY. The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production, and for areas for natural resource extraction and energy development, without the interference of other, incompatible land USES." The subject property is zoned Agricultural (A). Solar Facilities are permitted as a Use by Special Review in the Agricultural zone district. The Use by Special Review process allows for adequate review by the Planning staff, Planning Commission, and the Board of County Commissioners, to ensure compatibility with surrounding land uses. Additionally, citizens are afforded adequate opportunities to express their concerns in the public hearing setting before any solar facility can be constructed on agriculturally- zoned land. Within the stated intent of the "Agricultural" Zone District is the specific reference to "natural resource extraction" and "energy development". This proposed solar power generation plant is in compliance with the intent of the "Agricultural" Zone District. Solar facilities allow farmers and ranchers another use for their land and a viable stream of income beyond traditional farming and ranching uses. The SEF does not permanently stand on the land, or contaminate it, allowing for the landowner should they decide to use this land for agricultural purposes after the 20-40 year SEF lifecycle. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. The subject parcel does fall within the Kersey CPA Intergovernmental Agreement Boundaries and per their response this project is not impactful to their master plans. Additionally, the proposed solar facility will be compatible with the remainder of the surrounding Area, which remains unincorporated. Much of the surrounding area is now, and will probably remain, agricultural in nature. In addition, oil/gas production will likely continue in the surrounding area. Solar development is very compatible with farming and ranching uses and oil/gas development. Renewable projects provide farmers and ranchers a viable alternate use to traditional farming and ranching uses on their land. Since there are no permanent structures being built as part of this proposal, the land can be returned to its agricultural use once the economic viability of the solar facility has ended. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. This development will positively impact the health, safety, and welfare of the inhabitants of the surrounding area and County. The SEF will create no airborne or ground contaminants, making it nonhazardous for residents near and far. The SEF is also nearly silent when operating, thus will not contribute to any noise pollution. The SEF will produce local electricity without adding any pollution to the air. The SEF will be fully fenced in with a security fence, making it inaccessible for trespassers and preventing potential hazardous situations. 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -1§ur -1pr COMWONITY 5 �?in.E 41111 010 • • Goldfinch Solar, LLC will build the SEF according to both building codes and Xcel's standards and will pose no threat to the health and viability of the electric grid, locally or throughout the front range. The addition of solar energy to the grid will further diversify the energy mix supplied by Xcel, preventing dependence on any one source of fuel and eliminating the risks associated. The SEF will also provide Weld County residents (who are Xcel customers) with the opportunity to choose their energy source and energy provide, increasing consumer choices and economic freedom. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. While this land is zoned for agriculture, it should not be considered as prime farmland. The Weld County Code defines prime and non -prime farmland as follows: "FARMLAND - WELD COUNTY NONPRIME: NONPRIME FARMLAND is low capability land that is not considered important land for food production. It may be composed of poorer soils prone to erosion or may have topographical limitations such as slopes or gullies." "FARMLAND - WELD COUNTY PRIME: The availability of a consistent supply of quality water must exist in order to have PRIME FARMLANDS. PRIME and PRIME if irrigated lands fall into upper capability classes as defined by the Natural Resource Conservation Service and Colorado State University Cooperative Extension Service and should be protected equally if irrigation water is available and they are located within a reasonable distance of water delivery STRUCTURES." For the following reasons, Goldfinch Solar, LLC believes this parcel falls into the nonprime farmland category: 1) Due to the decrease of water every year, it will put an end to the landowner being able to farm the full area. The landowner currently must purchase water to finish the crops to harvest. Having the SEF on a portion of the land will then allow for the landowner to use the water they have without having to purchase more water. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. This location does not fall within any of the zoning districts. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. Goldfinch Solar, LLC will need to apply for the following permits to complete this SEF: County: Access Permit State: COR400000 Stormwater Discharge to be applied for and obtained following USR issuance Federal: N/A 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -'fur -1pr COMWONITY 5 �?in.E Use by Special Review for a Solar Energy Facility Goldfinch Solar, LLC Parcel ID No. 080130400002 & 080130400003 Public Works/Development Review Questionnaire 1.

Goldfinch Solar, LLC is leasing this land from Janice Marie and Donald Carson This project is in the landowner's best interest, as noted in their letter attached to this application. The Carson's, owner of the parcels, currently have this land as an irrigated corn field. Due to the decrease of the water every year, it has become uneconomical to subsidize the water to finish the crops out to harvest. While the payments generated from the lease will provide the landowner with diversified sources of income. In contrast to agricultural earnings, the payments generated by the solar lease will be regular, fixed payments, and will increase annually without fail. Solar is ultimately one of the best uses that the landowner could pursue in this area. Solar produces no pollutants or contaminants, making it safe for the surrounding mixed uses. Additionally, solar produces no noise pollution, no heavy traffic, and the system will be screened from the public, and therefore this use will not cause any nuisances. The project is not located within a residential neighborhood. Solar is not a permanent use either and the land will be returned to its current state after the system is retired. Even with solar present onsite, this project will still benefit the agricultural community of Weld County by serving as a grazing field for local sheep ranchers. Goldfinch Solar, LLC is solely responsible for the management of all vegetation within the permitted area. Rather than mowing, should the landowner and Goldfinch Solar, LLC decide to, we will work in partnership with a Weld County rancher, with whom we have a pre-existing relationship. The rancher's sheep will graze on the vegetation, providing his flock with a free food source while keeping the site pristine. During operations the land will lie fallow allowing time for soils to replenish nutrients and minerals. When the solar facility is removed the project area can be returned to farming. This use doesn't conflict with existing land use and is done with an eye toward improving future land use. Goldfinch Solar, LLC develops solar facilities on land that produce the highest and best use and intends to leave the land in a better place than when the project began. As presented in this application, this project is in compliance with the Weld County is developed with a focus on good stewardship of the land and a neighborly spirit.

The intent of this Decommissioning/Reclamation Plan is to provide a comprehensive plan for removal of the solar facility after its useful life and/or the termination of power generation operations; and to return the subject property to conditions that existed prior to the solar facility's construction. The solar power generation facility has an estimated useful life of 30 years or more, with an opportunity for a life of 50 years or more with equipment replacement and repowering. At the end of the useful life of the facility, Goldfinch Solar, LLC will cease power generation, decommission the facility, and remove the components of the facility from the subject property. The site will be reclaimed and returned to the agricultural use that existed prior to the facility being constructed (or if the landowner requests to keep the land and access roads as is). This Decommissioning/Reclamation Plan is subject to refinement should future best practices or alternate methods be developed by the solar industry, during the life of this facility. Goldfinch Solar, LLC will follow solar industry standards and best management practices (BMPs) that exist at the time of decommissioning and reclamation of the site. 1.1 Procedures for Decommissioning the Solar Facility After Useful Life & Termination of Power Generation The solar facility consists of numerous recyclable materials, including glass, semiconductor material, steel, aluminum, copper, and plastics. When the facility reaches the end of its operational life, the component parts can be dismantled, and for the most part, salvaged or recycled at properly licensed facilities. Some site features, such as internal roads, driveways, drainage features/improvements, and electrical interconnections may remain on the site, depending upon the anticipated future use of the property. All such improvements, that are scheduled to remain after the decommissioning of the site, will be approved by the Weld County Department of Planning Services. The following steps will be followed in the decommissioning of the solar facility: ■ Approximately one year prior to the planned decommissioning of the facility, Goldfinch Solar, LLC will schedule a pre -closure meeting with the Weld County Department of Planning Services to discuss the process for the site decommissioning and restoration. The final decommissioning details will be developed through consultation with the Weld County Department of Planning Services and other departments and agencies that have jurisdiction over activities in the decommissioning process. Any required permits will be obtained prior to implementation of the Decommissioning/Reclamation Plan. ■ Appropriate temporary (construction -related) erosion and sedimentation controlled BMPs will be applied during the decommissioning phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality. ■ Per 23-4-1030.4b: Effectively, the decommissioning of the solar facilities proceeds in reverse order of the installation including all installed equipment will be removed at least three (3) feet below grade: 1 A site -specific health and safety plan shall be developed, prior to beginning decommissioning activities, which incorporates the specific sequence and procedures to be followed. 2. Coordination with local departments and agencies to develop route plans and obtain necessary permits for the transportation of materials and equipment to and from the site. 3. The solar facility shall be disconnected from the utility grid. This process will be coordinated with Xcel Energy. 4. PV modules shall be disconnected, collected, and transported to a properly licensed recycling facility. 5. Above ground and underground electrical interconnection and distribution cabling shall be removed and salvaged or recycled off - site at an approved recycling facility. 6. The aluminum racking that supports the PV modules shall be removed and salvaged or recycled off -site at an approved recycling facility. 7. PV module support steel and support posts shall be removed and salvaged or recycled off -site at an approved recycling facility. 8. Electrical and electronic devices, including transformers, semiconductors materials, inverters, and batteries, shall be removed and salvaged or recycled off -site at an approved recycling facility. 9. Concrete foundations shall be removed and will be recycled off -site at an approved concrete recycling facility. 10 Fencing shall be removed and will be recycled off -site at an approved recycling facility. 11 The site will be restored to its original condition (or if the landowner requests to keep the land and access roads as is), including any necessary sculpting of soils to match existing natural contours and the re -seeding of native grasses. Any soil that had been re -located for construction purposes will be redistributed on the site or used for landscaping purposes. Soils will be compacted for those areas where foundations or piers have been removed. 1.2 Equipment to be Used for the Decommissioning of the Solar Facility The decommissioning of the solar facility will be undertaken using traditional heavy construction equipment, including front-end loaders, bull dozers, cranes, excavators (track- mounted and rubber -tired), water tankers, trucks, and pick-ups. Semi -trucks will be used to transport materials to off -site salvage or recycle centers. 1.3 Dust Mitigation During the Decommissioning Phase Water tankers will be used to help control dust while the decommissioning activities are occurring on the site. During the decommissioning of the facility, Goldfinch Solar, LLC will exercise BMPs to limit fugitive dust from being airborne and traveling beyond the property lines. Dust control efforts will be monitored by the site foreman on a regular basis to ensure fugitive dust is adequately controlled. Water spray will be applied, as needed, to unpaved areas during periods of dry weather. Care will be taken not to over - apply water and create mud. Vehicle tracking devices will be installed at truck exit drives, per the requirements of Weld County. Vehicles operating on the site during the decommissioning phase will limit their speed to 15 mph or less, to minimize dust emissions. 1.4 Decommissioning/Reclamation Cost Estimates Decommissioning/reclamation cost estimates, which shall be updated every five (5) years from the establishment and submittal of the Security, shall include all costs associated with the dismantlement, recycling, and safe disposal of facility components and site reclamation activities, including the following elements: Decommissioning: Fencing Structures Modules Electrical Site Restoration $3,000.00 $60,000.00 $30,000.00 $20,000.00 $25,000.00 Total $138,000.00 Clarifications — Inclusions and Exclusions 1.

Prepared by: Kristy Weyerm an Project Development Manager Use by Special Review for a Solar Energy Facility Goldfinch Solar, LLC Parcel ID No. 080130400002 & 080130400003 DEVELOPMENT STANDARDS STATEMENT Goldfinch Solar, LLC, a Colorado limited liability company, is pleased to present our application for a Use by Special Review for a Solar Energy Facility ("SEF") on property owned by Janice and Donald Carson and located on Parcel ID No. 080130400002 & 080130400003 part of the SE/4 of Section 30, Township 6 North, Range 64 West of the 6th P.M. in Weld County, CO. Goldfinch Solar, LLC is proposing a 7,000 kW AC (6890 kW DC) SEF which will occupy approximately 29.31 acres on the W/2SE/4 of the roughly 147 acre parcel(s). The current zoning on the parcel is Agricultural (A), and this parcel currently sits as irrigated corn farmland. This 7,000 kW -AC project will use standard photovoltaic technologies that have been proven safe and effective through deployment across the United States in thousands of utility or commercial -scale solar developments. The solar panels are mounted to single axis tracking arrays, which sit parallel to the ground and follow the path of the sun across the sky. The panels face east in the morning, lay flat at noon, and face west in the evening. The tracking arrays produce DC current, which is converted into AC current by inverters for synchronization and delivery of energy into the utility's distribution grid at a utility transformer. The modules utilize a non- reflective glass which eliminates glare concerns and all electrical cables on the improved area will be buried, except for the direct current string wires that connect between solar collectors, direct current collection circuits between rows of solar arrays that are no more than four (4) feet above grade crossings, substations, switch yards, and circuits voltages greater than 34.5 kilovolts (where necessary.) There will be no permanent employees on site during operation, and maintenance visits are expected to occur quarterly on average. The appearance of the solar arrays is uniform and symmetrical. Solar panels will not exceed ten (10) feet in height above the grade, at maximum tilt. The facility will be constructed in accordance with IBC 2021 and NEC 2020 and will be surrounded by an 8' high game fence made of 4' X 4" reinforced mesh. All setbacks are in accordance with the development standards and are identified on T.100 of the Sketch Plan. Fence details are on page C.102 of the Sketch Plan. The adjacent parcel landowners sharing borders with the project parcel will also be notified. Please see the enclosed Buffer Report and an example Neighboring Landowner Notice Letter for details. Goldfinch Solar; LLC will use historic access for this SEF off WCR 64 and will therefore need to cooperate with Weld County for traffic analysis for an access permit. The access turns north off WCR 64 and is located approximately 0.33 miles west of the intersection WCR 51 and WCR 64. This access road has historically been used by the landowner and tenant farmer for agricultural purposes, and it was also used by the former Oil and Gas operator (all Oil and Gas wells and facilities have been removed). The road will be used as a shared access with the landowners and tenant farmer. The entrance to the site will include a 25' wide all-weather access driveway with an acceptable alternative to a hammerhead turnaround. 1724 Gilpin Street, Denver, CO 80218 m info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM caMwuNiTr sa�aa This project site has no areas of extreme sloping and will not require any grading work. This SEF will abide by all dust mitigation standards laid out by the County, as described in our Dust Mitigation Plan This soil of the project area is classified as Type B and may require the addition of a detention pond onsite to aid in runoff management. The project is not located within any FEMA designated Special Flood Hazard Areas. The Stormwater Management shall be addressed via the attached Surface Drainage Analysis. Conceptual design details can be found in the enclosed Sketch Plan. The operational life of an SEF is generally between 20-40 years. The SEF has an initial 20 -year contract with Public Service Company of Colorado (Xcel) to sell power into the Xcel Electric grid, and the major equipment components have warranty options for up to 30 years, with a useful life of 35-40 years. Upon decommissioning, Goldfinch Solar, LLC will entirely remove all SEF components (fencing, steel racking, cabling, solar panels, and associated interconnection equipment) and undertake measures to restore the land to its original state, as addressed in the attached Decommissioning Plan. Goldfinch Solar, LLC will obtain all required permits and approvals, including utility interconnection agreements, prior to commencing construction. The project engineers and general contractor will be made up of local experienced individuals licensed in Colorado, who will ensure that all required codes and standards are followed throughout the design and construction. The project will comply with all applicable provisions in the Weld County Code. Goldfinch Solar, LLC looks forward to working with Weld County to successfully complete this proposed development and bring the benefits of community solar energy to the County. 1724 Gilpin Street, Denver, CO 80218 m info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM )1/4 caMwuNiTr sa�aa Stormwater Drainage Study • kSunShare irr. COMMUNITY SOLAR Date: To: From: Project: Subject: 11/18/2024 Goldfinch Solar LLC Allyson Williamson, TRC Companies 700 Highlander Blvd., Suite 210 Arlington, TX 76015 Goldfinch Solar On -Site Drainage Study FOR PERMITTING PURPOSES ONLY T ysen e aliamksatv Prepared by or under the Direct Supervision of: Allyson Williamson, P.E. 60360 "11/18/2024" Goldfinch Solar LLC is pursuing the development of Goldfinch Solar, a photovoltaic energy generation facility at a 28.05 -acre site located approximately 8.5 miles northwest of Greeley, Colorado, northwest of Co Rd 64 and Co Rd 51 with access from Co Rd 64 (See Appendix A -Site Plans C-1 & C-2). The existing site is currently used for agricultural purposes with average slope of 3.0%. This drainage study was prepared to summarize findings from a hydrologic analysis of the project site to identify the potential stormwater impact from the proposed solar project and develop appropriate drainage best management practices (BMPs) to address the impact. This drainage study was prepared to comply with the requirements from Weld County Engineering and Construction Criteria (WCECC) Manual, updated March 2024. Proposed Project The proposed solar projects will consist of pole mounted photovoltaic (PV) arrays, a gravel access road and concrete equipment pads. The impervious area generated by the solar panel posts are considered de minimis, thus the only considerable impervious areas on site are the equipment pads and gravel access road. Rainfall runoff from the panels will not be concentrated and flow under the pole mounted PV panels matches the pre -development flow patterns. Additional improvements associated with this project are limited to gravel drives for vehicle access and concrete pads for electrical equipment (see Appendix A - Site Plans C-1 & C-2). No public access or utility infrastructure improvements are anticipated in this study. Site Drainage Currently, the existing site does not have any regional retention or water quality features. The soils in the area consist of hydrologic soil group (HSG) B and C given by the Natural Resources Conservation Service (NRCS — Appendix B). Any offsite flows appear to follow the existing ditches and are not expected to affect the project site. See Appendix A for the drainage area maps and details. A hydrologic analysis was prepared using the Rational Method based upon requirements from WCECC Manual. The analysis provided estimated peak flow rates for the 100 -year storm under both pre- and post -development conditions. The design rainfall depth for a 1 -hour, 100 -year storm is 2.70 inches based upon NOAA Atlas 14: Precipitation -Frequency Atlas. Stormwater Drainage Study NOAA Atlas 14: Precipitation -Frequency Atlas. The Rational Method equation shown below was used to determine the peak flow rates from Drainage Area A, B, and C. Existing conditions for all three drainage areas were determined to be "Greenbelt, Agricultural" which correlates to a 2% impervious value per WCECC Table 5-2. Proposed conditions were determined to be "Greenbelt, Agriculture", "Packed Gravel", and "Paved" which respectively correlates to 2%, 40%, and 100% per WCECC Table 5-2. Area -Weighted Runoff Coefficient for each pre and post development drainage areas are calculated by using percent impervious from Table 5-2 and runoff coefficient from Table 5-3 through 5-5. The drainage area imperviousness and resulting peak flow rates from pre -and post -development conditions are summarized below. See Appendix C for the runoff coefficient calculations. Q If) Where: - Runoff flow rate in cubic feet per second (cfs) C— Weighted Runoff Coefficient /— Rainfall Intensity in inches per hour (in/hr) A -Area of the basin in acres (ac) Pre -development Runoff Calculation Parameters Drainage Area Area, A (ac) Weighted Coefficient, Runoff C Intensity, Rainfall (in/hr) I A 20.92 0.5086 5.13 B 32.64 0.4270 5.33 Post -development Runoff Calculation Parameters Drainage Area Area, A (ac) Weighted Coefficient, Runoff C Intensity, Rainfall (in/hr) I Impervious % Weighted ac/total (impervious Percent ac) A 20.92 0.5086 5.13 2% B 32.64 0.4302 5.33 2.67% 100 -year Runoff Calculation Results Drainage Area Pre -development Peak Flow (cfs) Rate Post Peak -development Flow (cfs) Rate DIFFERENCE (cfs) A 54.60 54.60 0.00 B 74.26 74.66 0.40 Based upon the above results, the increase of impervious area would produce a 0.0% and 0.5% rise in the peak flow rate for drainage areas A, and B respectively. Since these rises are not significant, detention basin facilities will not be proposed. Instead, grass swales will be introduced as shown in Appendix — A Site Plan C-2 to dissipate energy and attenuate any potential flow increase from gravel roads and concrete pads. A level Stormwater Drainage Study Erosion Control/Stormwater Management Plan Temporary construction sediment control such as silt fences shall be shown on final construction plans. Such measures will be included in the erosion control plan and detail sheets within the final construction documents. Grass swale sizing calculations are summarized in Appendix D. Conclusion The drainage study and attached drainage maps were produced in accordance with requirements from Weld County Engineering and Construction Criteria Manual, updated January 2021. The existing stormwater flow characteristics are expected to remain unchanged and increases in peak flow rates have been proven to be negligible. A basin type of stormwater detention would not be necessary. Improvements proposed with the project site are limited to a gravel paved drive and one concrete equipment pads. No public access or utility infrastructure improvements are anticipated at this time. The proposed development will not alter historic drainage patterns and adjacent and downstream property owners.

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. Rating Options Aggregation Method.

The existing site is currently used for agricultural purposes with average slope of 3.0%. This drainage study was prepared to summarize findings from a hydrologic analysis of the project site to identify the potential stormwater impact from the proposed solar project and develop appropriate drainage best management practices (BMPs) to address the impact. This drainage study was prepared to comply with the requirements from Weld County Engineering and Construction Criteria (WCECC) Manual, updated January 2021. Proposed Project The proposed solar projects will consist of pole mounted photovoltaic (PV) arrays, a gravel access road and concrete equipment pads. The impervious area generated by the solar panel posts are considered de minimis, thus the only considerable impervious areas on site are the equipment pads and gravel access road. Rainfall runoff from the panels will not be concentrated and flow under the pole mounted PV panels matches the pre -development flow patterns. Additional improvements associated with this project are limited to gravel drives for vehicle access and concrete pads for electrical equipment (see Appendix A - Site Plans C-1 & C-2). No public access or utility infrastructure improvements are anticipated in this study. Site Drainage Currently, the existing site does not have any regional retention or water quality features. The soils in the area consist of hydrologic soil group (HSG) B and C given by the Natural Resources Conservation Service (NRCS — Appendix B). Any offsite flows appear to follow the existing ditches and are not expected to affect the project site. See Appendix A for the drainage area maps and details. A hydrologic analysis was prepared using the Rational Method based upon requirements from WCECC Manual. The analysis provided estimated peak flow rates for the 100 -year storm under both pre- and post -development conditions. The design rainfall depth for a 1 -hour, 100 -year storm is 2.70 inches based upon NOAA Atlas 14: Precipitation -Frequency Atlas. Stormwater Drainage Study NOAA Atlas 14: Precipitation -Frequency Atlas. The Rational Method equation shown below was used to determine the peak flow rates from Drainage Area A, B, and C. Existing conditions for all three drainage areas were determined to be "Greenbelt, Agricultural" which correlates to a 2% impervious value per WCECC Table 5-2. Proposed conditions were determined to be "Greenbelt, Agriculture", "Packed Gravel", and "Paved" which respectively correlates to 2%, 40%, and 100% per WCECC Table 5-2. Area -Weighted Runoff Coefficient for each pre and post development drainage areas are calculated by using percent impervious from Table 5-2 and runoff coefficient from Table 5-3 through 5-5. The drainage area imperviousness and resulting peak flow rates from pre -and post -development conditions are summarized below. See Appendix C for the runoff coefficient calculations.

Since these rises are not significant, detention basin facilities will not be proposed. Instead, grass swales will be introduced as shown in Appendix — A Site Plan C-2 to dissipate energy and attenuate any potential flow increase from gravel roads and concrete pads. A level spreader will be installed to ensure that the flow from the proposed swale is converted back to sheet flow before being released onto any of the adjacent properties. Stormwater Drainage Study Erosion Control/Stormwater Management Plan Temporary construction sediment control such as silt fences shall be shown on final construction plans. Such measures will be included in the erosion control plan and detail sheets within the final construction documents. Grass swale sizing calculations are summarized in Appendix D. Conclusion The drainage study and attached drainage maps were produced in accordance with requirements from Weld County Engineering and Construction Criteria Manual, updated January 2021. The existing stormwater flow characteristics are expected to remain unchanged and increases in peak flow rates have been proven to be negligible. A basin type of stormwater detention would not be necessary. Improvements proposed with the project site are limited to a gravel paved drive and one concrete equipment pads. No public access or utility infrastructure improvements are anticipated at this time. The proposed development will not alter historic drainage patterns and adjacent and downstream property owners.

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. Rating Options Aggregation Method.

The intent of this Dust and Weed Mitigation Plan is to provide a comprehensive plan for control of dust, noxious weeds, and any drainage issues that could cause erosion from the solar facility. 1.1 Dust Mitigation During the Construction Phase Water tankers will be used to help control dust while the construction activities are occurring on the site. During the construction of the facility, Goldfinch Solar, LLC will exercise Best Management Practices (BMPs) to limit fugitive dust from being airborne and traveling beyond the property lines. Dust control efforts will be monitored by the site foreman on a regular basis to ensure fugitive dust is adequately controlled. Water spray will be applied, as needed, to unpaved areas during periods of dry weather. Care will be taken not to over - apply water and create mud. Vehicle tracking devices will be installed at truck exit drives, per the requirements of Weld County. Vehicles operating on the site during the construction phase will limit their speed to 15 mph or less, to minimize dust emissions. 1.2 Noxious Weed Management The Colorado Department of Agriculture (CDA) and Weld County both require landowners to prevent the spread of State Listed Noxious Weeds. Construction activities on the site have the potential to introduce new noxious weed species to the site or spread existing species on to or off the site. This noxious weed management program was developed to prevent further spread of noxious weeds. Goldfinch Solar, LLC will comply with CDA and Weld County regulations through implementation of this plan. Periodic reviews and updates to this plan will be completed as necessary to keep it current with noxious weed control issues. This plan will be implemented throughout the life of the solar facility. Appropriate management actions will be implemented whenever noxious weed species are observed growing within the project area. The goals of weed management are to: 1. Identify and manage noxious weeds within and immediately adjacent to the project areas to be disturbed and after the area has been reclaimed. 2. Conduct pre-treatment and post -treatment evaluations and continue or modify treatment measures as necessary. 3. Minimize the potential for transportation and importation of noxious weed species. 4. Educate field personnel in order to encourage compliance with weed management program goals and assist with identification and control efforts. To prevent or minimize the infestation and spread periodic inspections of the project area during the beginning, middle, and end of the growing season will evaluate presence or absence, degree of invasion, and the response of previous treatments. Goldfinch Solar, LLC's operational staff will conduct regular site inspections and ensure the implementation of this plan. Specific treatment methodologies and timetables will be developed based on species of concern, location and extent of the infestation(s), and other pertinent factors. 1.2 (a) Noxious Weed Prevention Noxious weeds are spread through dispersal of seed and/or transport of plant propagules (i.e., spores, seeds, roots, etc.). The most effective way to control noxious weeds is to prevent their introduction into the site in the first place. A combination of methods and practices will be employed to prevent the introduction of weed species and their regeneration within the project area. The following methods and practices may be employed, either singly or in combination, to prevent the introduction of weeds into the solar site: 1. A thorough cleaning of equipment will be conducted before entering the project area to prevent the introduction of seed and plant propagules from other sites. 2. Seed mixtures used for revegetation or temporary site stabilization will be free of noxious weeds. 3. Hay, straw, and/or other materials used for mulch or other purposes will be certified weed free. 4. A periodic inspection will be conducted to identify any new weed infestations that may have occurred. Any new infestations will be scheduled for management before they become well established and/or spread. 5. Communication and coordination with adjacent landowners whose property is infested with noxious weeds that may threaten the site should occur. Establishing partnerships for weed management within the local area is essential for successful long-term weed management. 6. Noxious and pest weed infestations that threaten natural and reclaimed areas will be treated with accepted Integrated Weed Management (IWM) methods. These methods are further discussed below. 1.2(b) Integrated Weed Management (IWM) An Integrated Weed Management approach will be implemented for the treatment of noxious weeds within the project area. An IWM approach enables selection of one or more weed management methods based on site specific environmental conditions and control needs. The following weed management methods will be considered for the project area: 1. Cultural — Planting native or desirable plant species for site colonization and promoting healthy vegetation communities in reclaimed areas. Prevent unnecessary disturbance through precise planning of construction projects and other activities. Prompt revegetation of disturbed areas. 2. Mechanical — Mowing, pulling, disking, and plowing may be used on weedy species for which these treatments are effective. 3. Biological — Introduction of insects or other biologic agents which are known to inhibit or prevent reproduction of noxious weed species. If biological agents are employed, control methods will be coordinated with the Colorado Department of Agricultural Insectary in Palisade, Colorado. 4. Chemical — Application of appropriate herbicides by a licensed applicator. All herbicides will be applied in accordance with the manufacturer's label and in accordance with Colorado laws. In some cases, only one control method may be warranted, while in other cases a combination of control methods may be appropriate. Control methods selected will be dependent upon species of concern, and the location and extent of the infestation. The use of IWM methods will protect pollinators, reduce hazards to wildlife, reduce the possibility of herbicide resistance, and minimize persistence and mobility of herbicides in the soil. Weed control methods and practices will be applied in a manner that conforms to applicable federal, state, and local laws. 1.2(13)1 - Cultural Control Germination and establishment of noxious weeds can be reduced by following accepted revegetation and vegetation management techniques that favor the growth of desirable plants. These include prompt seeding and revegetation of disturbed areas with appropriate seed mixes, maintaining optimum fertility and moisture levels, planting at optimum density of pure live seed, minimizing use of fertilizers, and selecting suitable species for revegetation. Minimizing areas of disturbance and exposed soil prevents opportunities for aggressive species to establish. A revegetation plan has been developed for the site that utilizes native species that are well- adapted to the site. Seeding native species in conjunction with other management practices will provide some level of competition with noxious weeds and minimize the opportunity for new infestations to become established. 1.2 (b) 2 - Mechanical Control Mechanical Control of noxious weeds can be an effective tool to physically disrupt noxious weed growth and seed development. A combination of mechanical methods may be used including tilling or disking, mowing, hand-held weed trimmers, mulching, hand -pulling, hoeing, or livestock grazing. Mechanical weed control practices must be applied with correct timing to maximize their effectiveness in preventing vegetation development or seed production. Annual weedy species may be readily controlled with mowing or physical removal. Perennial species such as Dalmatian toadflax have extensive root systems. For such weed species, mowing may only control seed production without seriously affecting the plant's survival. Mowing after seed production has occurred may spread the plants. Disking or tilling areas containing perennial noxious species may increase the area of infestation due to root sprouting. In most cases, mechanical control methods used alone are not effective against noxious weed species. 1.2 (b) 3 - Biological Control Biological control of noxious weeds can be an effective tool to physically disrupt plant growth and seed development. A combination of biological methods may be used including introduction of insect weed predators and species -specific plant diseases. Biological weed control methods and practices will be applied with appropriate timing to maximize their effectiveness in preventing seed production. It must be noted that the use of biological controls normally does not eradicate an infestation of weeds; rather they are capable of reducing weed species vigor and reproduction. The Colorado Department of Agriculture's Biological Pest Control Program has on -going biological control programs for several noxious weed species. Note, the use of insect bio-controls typically require large populations of the target weed to sustain the population of bio-control agents. Biological controls should not be expected to eliminate the entire infestation of a noxious weed, but instead to bring the infestation down to a more manageable level. 1.2 (b) 4 - Chemical Control Chemical control of noxious and pest weeds can be an effective tool to disrupt plant growth and seed development. Herbicides can kill targeted species, prevent development and/or germination of noxious weed seed, can be used with minimal disturbance to soils, and in some cases, can be selective to specific species or groups of plants. Herbicides must be applied at the appropriate time to maximize their effectiveness in preventing seed production, for disrupting plant establishment and growth, or achieving kill of noxious species. To avoid development of resistance to a particular herbicide through repeated use over prolonged periods of time, herbicides with varying modes of action to be used. Also, herbicides will be applied according to manufacturer's label recommendations (i.e., application rate, method, and timing) to prevent development of plant resistance. Herbicide selection will be based on weed emergence, timing of application, past applications, and ground and weather conditions during the applications. Successful IWM begins with an understanding of the target plant species and the environment within which it grows. Next, the physiologic effects of an herbicide on plant growth and development must be understood. Understanding a pesticide's chemical nature is also important in minimizing impacts to non -target species, the applicator, endangered species, and pollinators, as well as surface water runoff hazards and leaching into groundwater. Every herbicide label contains information regarding environmental hazards. This information will be evaluated for each herbicide considered for use at the site and herbicides will be selected which pose minimal to no environmental hazards. All pesticides will be handled with care and applied by qualified personnel. Properly identifying the weed problem and the most effective chemical control method for use during the plant growth cycle is critical to effective weed control. Equipment will be properly calibrated before herbicides are applied and appropriate Personal Protective Equipment (PPE) will be used. Empty containers will be disposed of promptly, safely and in accordance with product labeling. Herbicides vary in the amount of time after an application before it is safe to re-enter the treated area without protective clothing and equipment. The site re-entry time is affected by the rate of application, size of the area treated and the amount of time to be spent in the field. For the safety of employees and contractors, the Restricted Entry Interval (RED listed on the herbicide's label will be followed. Appropriate herbicide application records will be maintained as specified by the CDA. 1.2 (c) — Monitoring and Follow -Up Even with effective weed management strategies, it often takes several seasons to eradicate or bring weed populations to an acceptable level. With well -established infestations, it is likely that a seed bank has developed in the soil capable of producing new plants for many years. An infestation of weeds can easily re -invade treated areas in one growing season if control and treatment activities are prematurely curtailed. Weed management efforts should be carried out over an adequate number of growing seasons to realize effective weed management within the target area. As with all weed management, this multi -season effort is best served by effective documentation of control efforts and continued vigilance in successive seasons of management. Information can be used to modify treatment priorities and weed management strategies over time. Vigilance is required against new infestations that may be moving into the site. These new sources of infestation may be worked into prevention and management plans as necessary. This weed management plan will be modified over time as site conditions change. Weed management strategies and priorities can be modified as weed infestations change in response to continued control efforts. 1.3 — Drainage and Erosion Control Installation of the solar facility will not alter existing drainage patterns or flow rates on the site and runoff water quality will not be impacted by the solar facility components. Installation of water quality or detention facilities would require clearing, grubbing, grading, and reseeding of a portion of the site and would likely increase the potential for erosion, sediment transport and concentrated flow. Accordingly, water quality and detention are not recommended for this project. Appropriate temporary (construction -related) erosion and sedimentation control Best Management Practices (BMPs) will be applied during the construction phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality.

There is one parcel that has a residential building within 500 feet of the proposed SEF area. Goldfinch Solar, LLC proposes the following fencing plan for the purposes of visual mitigation: A six-foot tall, offset -picket composite privacy fence along the southwest corner of the proposed SEF site. The proposed fence is a composite fencing rather than wood due to its increased durability. Additionally, the offset -picket design will provide opaque screening while also allowing wind to pass through (and therefore mitigating potential hazardous situations that could arise during high winds). This fence is proposed in addition to the security fence running the entire perimeter of the project. Please see the fencing plan and additional fence details on the next page. Gilcrest Solar, LLC has used this exact method of screening for our Gilcrest V SEF, also in Weld County, to great success. ibotter? lainShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 m info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM i .fie i lli ull ��IIII'ilDIA"lllll�� !

This narrative is intended to provide traffic -related information and identify potential Project impacts to affected roadways within Weld County. The following information is included in this narrative: • Project Location, Components and Construction Schedule • Designated Travel Route • Daily Vehicle Trip Generation • Conclusions Project Location, Components and Construction Schedule Location - The Project will occupy approximately 34.5 acres (within Weld County Parcel No. 080130400002 & 080130400003` located near WCR 64, west of the intersection of WCR 64 and WCR 51, in a portion of the W2SE4 in Section 30, Township 6N, Range 64W. Components - The Project generally includes: 7 -megawatt (MW) alternating (AC) or 8.01 MW (DC) solar energy conversion system comprised of 11,526 tracker solar modules mounted on steel I -beams; concrete pad -mounted transformer and interconnect; inverters mounted at the end of array rows; an access drive with room for emergency turn around; and perimeter fence with gate. Construction Schedule — Once the use by special review permit is finalized, the construction phase is anticipated to take approximately one hundred & nine (109) days. Based on this, the following preliminary schedule has been prepared: • Solar Facility Components First Deliver • Perimeter Fence Installation • Solar Panel Foundation Installation • Racking, Trenching, Wiring • Solar Panel Installation • Inspection & Set Meters • System Testing & Commissioning Day 1 Day 1 to Day 11 Day 5 to Day 30 Day 30 to Day 64 Day 64 to Day 94 Day 94 to Day 99 Day 99 to Day 109 Designated Travel Route The designated travel route includes WCR 64 and WCR 51, west approximately 0.33 miles, then north into location. The following is a brief description of the access route roadways. Both WCR 64 and WCR 51 are gravel roadways with a posted speed of 55 mph. The access into 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com o 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E the location is a historical access used by the landowner and farmer. Project -related traffic is not expected to impact on the area. Daily Vehicle Trip Generation and Distribution Project development may be divided into the following 3 phases: material and equipment delivery; facility construction; and facility maintenance). The following Table 1 illustrates the estimated average daily trip generation by vehicle type for each Project phase. Table 1 — Vehicle Trip Generation Project (Time) Phase Vehicle Type Estimated Vehicle Gross Weight Number of Vehicles Per Day Maximum Average Vehicle Per Day and Trips Equipment (approx. Material 1 and Delivery week) Conex Container and Delivery Trucks 30,000-50,000 lbs. 5-10 10-20 Equipment Trucks Hauling 20,000-40,000 lbs. 0-2 0-4 Max —14/Ave - 8 Solar Facility Installation (3-4 months) Passenger Vehicles 2,000 to 10,000 lbs. 5-12 10-24 Fuel Truck 20,000 to 30,000 lbs. 1 2 Material Delivery Truck 20,000 to 30,000 lbs. 1 2 Max — 28/Ave - 20 Operations (ongoing operational) once Utility Vehicle Truck) (Pickup 2,000 to 10,000 lbs. 1 per month or less Max — 2/Ave - 0 As illustrated in Table 1, the majority of traffic generated as a result of solar facility installation shall occur during the 3-4 month solar facility installation (max 28/ave 20vtpd). This traffic will generally be site worker passenger vehicles. Most of the heavy truck traffic including conex container delivery (30- 50 conex containers/delivery trucks) and equipment (rubber tire loader, pile driver, forklift) delivery and pickup will travel to and from the Project between 8:00 AM and 4:30PM. Project -related traffic during all phases will not be significant during AM and PM peak periods. Conclusions 1 The Project is expected to generate up to 24 vehicle trips per day during material and equipment delivery (anticipated to be one week at the beginning of the project and one week at the end of the project), 24 vehicle trips per day during solar facility installation (3-4 months) and 2 vehicle trips per month during solar facility operation. 2. Daily Project -related truck traffic is not expected to impact AM and PM peak traffic periods. The construction of the Project should not negatively impact the transportation pattern in the area. 3. As proposed, the solar facility installation (material/equipment delivery approximately 1 - week, solar facility installation approximately 3 months and approximately once per month for solar facility operations) is not anticipated to create adverse traffic -related impacts in the area or on Weld County roads. Based on anticipated vehicle type and weight (from 1724 Gilpin Street, Denver, CO 80218 info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM 11/4 -' §ur -1pr COMWONITY 5 �?in.E Table 1), the Project is not anticipated to degrade/damage Weld County roads. 4. There are no anticipated improvements required to any Weld County roads in order to serve the Project, since after the construction period, the facility is unmanned.

I am the owner of these parcels and wish to express my support for this project. My family purchased this property in 1964, and I, along with my family have farmed and lived on this land ever since. throughout the years this land has been used for silage corn and other types of agriculture uses. I have elected to lease my land to Goldfinch Solar, LLC to house their Goldfinch solar project. As a farmer in Weld County, I was particularly interested in leasing my land for this project as it presented a good economic opportunity. With the decrease of water every year, it has become very expensive to purchase the water we need to finish the crop out to harvest. I have been working with Goldfinch Solar, LLC since 2022 and I have confidence in their ability to deliver a safe and effective solar array. Goldfinch Solar, LLC has worked diligently to learn about the land, the challenges it presents, and the County requirements that they will need to meet. I also have confidence in their ability to work well with, and honor the best interests of, their landowners, such as myself. Goldfinch Solar, LLC will own and operate the solar array for its entire lifecycle and through decommissioning, which offers me peace of mind as the lessor or the land. I know that Goldfinch Solar, LLC is invested in the project and will have continued high standards for site maintenance and land stewardship. I look forward to the development of this project and the continued relationship between my husband and I, Goldfinch Solar, LLC, and the County. Thank you for your time.
