SunShare is proposing a 5,000 kW AC (5,967 kW DC) SEF which will occupy approximately 31.7 acres on the northern half of the roughly 80 acre parcel. The landowner, Kaycee Lytle, approached SunShare to help develop this solar project. As outlined in his attached Letter of Support, he invited the project for "three specific reasons: water, efficiency, and economics." He owns one share of irrigation water, which is only about 10% of the water currently needed to completely irrigate the 80 -acre farm to its full potential. Lytle Farms is, essentially, almost completely reliant upon renting water, creating immense risk and vulnerability. Market rates also make the purchase of water (were it to even become available) wholly uneconomical as costs would far exceed any possible return on investment. The addition of the solar project reduces the amount of farmed land from 80 acres to 30-35, and the income generated from the solar lease payments has partially aided Lytle Farms in acquiring a subsurface drip irrigation system on the remaining 30 acres. In all, they will be reducing their water needs by 70%, and, due to the efficiency of the irrigation system, Kaycee believes their yields will only decrease by 25-30% (even though the land being farmed is decreasing by 50%). The revenues received from the solar project are much greater than the revenues the Lytle's generate from farming the same ground that the project will sit on, and the income generated will be used to pay for continued renovations to the farm, to grow their livestock operation, to reduce debt, and to further improve their agricultural activity onsite.

Rebecca Parker NMI' PUBLIC STATE OF COLORADO NOTARY ID# 20191021092 MY COMMISSION EXPIRES JUNE 25, 2923 My commission expires: 69 / ZS /Zo Z3 Witness my hand and official seal: Use by Special Review - Medium Scale Solar Energy Facility Questionnaire for BecLee Solar LLC, PID 080322300023 1. Explain the proposed use and business name. SunShare LLC, d/b/a BecLee Solar LLC proposes a Medium -Scale Solar Energy Facility (SEF) to be placed at Weld County PID 080322300023. The SEF will have a capacity of 5,000 kW AC and will cover approximately 30.5 acres on the northern portion of the total parcel. 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 BecLee solar garden, SunShare 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. SunShare's BecLee solar garden 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 completement Weld County's numerous other energy generation industries and County's place as the energy capital of Colorado. The BecLee solar garden 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 owns one share of irrigation water, which is only about 10% of the water currently needed to completely irrigate the 80 -acre farm to its full potential. Lytle Farms is, essentially, almost completely reliant upon renting water, creating immense risk and vulnerability. Market rates also make the purchase of water (were it to even become available) wholly uneconomical as costs would far exceed any possible return on investment. • The addition of the solar project reduces the amount of farmed land from 80 acres to 30-35 acres, and the income generated from the solar lease payments has partially aided the landowner, Lytle Farms. in acquiring a subsurface drip irrigation system on the remaining 30 acres. In all, they will be reducing their water needs by 70%, and, due to the efficiency of the irrigation system, and their yields will only decrease by an estimated 25-30% (even though the land being farmed is decreasing by 50%). 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share • The revenues received from the solar project are much greater than the revenues that the Lytle's generate from farming the same ground that the project will sit on, and the income generated will be used to pay for continued renovations to the farm, to grow their livestock operation, to reduce debt, and to further improve their agricultural activity onsite. • 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 in the County will further diversify the County's energy mix and further its role as an energy leader in Colorado. • 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 specific location of the project has historically been used for oil and natural gas extraction and agriculture. This land is not currently incorporated into the city limits of any city in Weld County. Noble Energy Inc., Petro -Canada Resources Inc., and Bristol Production Inc have all previously housed oil and gas operations on this site, however Noble is the only company still operating on the parcel. Noble has two batteries and a well onsite, all of which are actively being removed (batteries) or plugged and abandoned (in the case of the well) at the time of this application. SunShare has designed the site so that it abides by the necessary P+A setback distance. The Landowner also currently farms the land; however he does not have water rights for this parcel and is therefore unable to secure any significant value from its current agricultural use alone. The landowner has leased a portion of his land to us and will farm the remaining portion. We have specifically designed our proposed SEF to allow for the best possible layout for farming. Our landowner, Kaycee Lytle, is in strong favor of this project and has written a letter to express his support, enclosed in this application. 4. Describe the proximity of the proposed use to residences. 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share There are no residences within 500 feet of the proposed SEF. The area overall is rural with limited residential buildings and units. The closest home is approximately 750 feet away and is owned by the owner of the project parcel. He is in favor of this project. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. Directly north of the SEF site is PID 080322000018, owned by Bickling Farms LLLP. The land is currently used for agricultural purposes and oil and gas activity. SunShare has notified Bickling Farms LLLP of this project and has received no protestations against, or concerns over, our proposed use. Directly east of the SEF site is PID 080322000012, owned by Hungenberg KHL Farms LLLP. The land is currently used for agricultural purposes as well as oil and gas activity. SunShare has notified Hungenberg KHL Farms LLLP of this project and has received no protestations against, or concerns over, our proposed use. Directly south of the SEF site are PIDs 080322300022, 080322300003, and 080327200078. The first two PIDs listed are owned by Kaycee Lytle, who is also the property owner of the parcel on which we will build the SEF. These parcels are used for agricultural and residential (Kaycee's family home is located on 080322300022) purposes. Kaycee is in favor of our proposed use (See Letter of Support). PID 080327200078 is owned by CORPORATION OF THE PRESIDING BISHOP. The land is currently used for agricultural purposes and oil and gas activity. SunShare has notified Corporation of the Presiding Bishop of this project and has received no protestations against, or concerns over, our proposed use. Directly West of the SEF site are PIDs 080322300001 and 080322300002. The latter parcel is owned by Donaldson and Company LLC. The land is used for agricultural purposes and oil and gas activities. SunShare has notified Donaldson and Company LLC of this project and has received no protestations against, or concerns over, our proposed use. PID 080322300001 is owned by Robert D. Taylor and Maria A. Taylor. The land is used for agricultural purposes. SunShare has not yet notified the Taylors of this project as we were not aware of the subdivision and sale of this parcel by Donaldson and Company to the Taylors, but we will send them a notification at this time and supply it to the County once sent. 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 contaminations pose no threat to the solar array. Solar is a safe and non -disruptive use for this particular parcel; it is primed to be placed amidst an area with various uses. 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share 6. Describe the hours and days of operation (i.e. Monday thru 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.). SunShare 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 benefitting 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 growth for the sheep, and if it is all safe 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 a total of 11,024 540w monocrystalline modules, forty 125kVA inverters, and 106 rows of single -axis trackers. The system consist of string level DC to AC conversion inverters, two main equipment pads with AC Recombiners, switchgear and MV step up transformers that connect to Xcel's grid. 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share 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 a materials and equipment laydown yard located on the interior of the facility. This laydown area will be approximately 50' X 250' in size. When the construction is completed, there will be in place a metal connex 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.

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 (31.7 acres on the north half of the parcel) is currently agricultural land, with a soon -to -be plugged and abandoned oil well„ 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 is also approximately 42,035 square feet of existing dirt road within the subject area, which is used by Noble energy to access their P+A well. There will be approximately 10,062 square feet of gravel access including the hammerhead turnaround. In addition, there will be a gravel laydown area that is approximately 12,500 square feet, for a total of 22,562 square feet of gravel surface area. There will be two (2) concrete transformer pads, each measuring approximately 48 square feet, for a total of 96 square feet of concrete area. 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? There will be two (2) 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. 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 will be screened by the solar array. There will be no outdoor storage associated with this proposed solar facility. 18. Describe the existing and proposed landscaping for the site. The entire affected area of the parcel has been used for agricultural purposes and/or oil and gas activity, and has been covered by crops, unplanted land, and oil and gas infrastructures such as wells and batteries. The remainder of the parcel has also been used for agriculture. The unaffected area's landscaping will not change. Once the construction phase is completed, the affected area within the solar facility fence will be seeded with a native seed mixture. As previously mentioned, there are no residences or commercial buildings within 500 feet, so screening trees and shrubs will not be needed. 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 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. 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share 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: "1. Ensure that surface development reasonably accommodates mineral extraction." SunShare'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. SunShare's SEF will be located next to a P+A well owned by Noble Energy and our design allows for Noble to access their well onsite. "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. By allowing for the installation of a SEF onsite, the landowner is re -allocating more resources (such as water) to his remaining farmed land, which will positively impact the farming onsite. Additionally, this project will allow the land to go fallow for many years, improving the soil conditions for future agricultural use. Solar produces no contamination or noise pollution and will pose no threat to surrounding land uses. "5.Energy development facilities should preserve agricultural areas and enhance the rural landscape."As stated above, this project will ultimately improve the land that it rests upon by allowing for more resources to be concentrated on the landowner's remaining farmed land. . 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 Ill 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 is 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." 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share The subject property is zoned Agricultural (A). Medium -Scale 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 use also does not permanently stand on the land, or contaminate it, allowing for the land to continue being used for ag purposes after the 20-40 year SEF lifecycle. As noted in his letter of support (attached in this application), the landowner and farmer of this parcel, Kaycee Lytle, feels that this proposed use will improve the agriculture on his land. The lease payments from the solar lease have helped him fund a drip -irrigation system on the portions of his land that will remain farmed, and the SEF will require no water, letting him reallocate the water he does have. In all, the drip -irrigation and allocation of water will allow for more predictable crops and higher yields. Please see Kaycee's letter of support for more elaboration. 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 not fall within any Intergovernmental Agreement Boundaries and therefore not impactful to the master plans of any municipalities in Weld County. 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 immediate 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. This proposed project was invited here by the landowner and farmer, as detailed in the attached letter of support. n. Kaycee Lytle, owner of the parcel and the farmer of the land, owns one share of irrigation water, which is only about 10% of the water currently needed to completely irrigate 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share the 80 -acre farm to its full potential. Lytle Farms is, essentially, almost completely reliant upon renting water, creating immense risk and vulnerability. Market rates also make the purchase of water (were it to even become available) wholly uneconomical as costs would far exceed any possible return on investment. By utilizing a portion of his land for solar, Kaycee is able to reduce the amount of water that his farm needs, as well as generate additional income which he intends to spend on further improvements to his land and agricultural operations. 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 is will not contribute to any noise pollution. The SEF will produce local electricity without adding any pollution to the air. The SEF will be full fenced in with a security fence, making it inaccessible for trespassers and preventing potential hazardous situations. SunShare 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's 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, SunShare believes this parcel falls into the nonprime farmland category: 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • ., Share 1) The landowner, Lytle Farms, only owns one share of irrigation water, which is only about 10% of the water needed to completely irrigate this 80 acre farm to its full potential. They are almost completely reliant upon renting water, which puts them at a vulnerable position. Their crops are far less productive due to the type of irrigation they use, and far less economical due to the need to rent so much water at high cost. The money generated from the solar lease for this SEF will pay for improvements to the farm and allow for increased productivity on the 30-35 acres that will remain farmed. 2) The land has Type C soil, making it prone to erosion. Per the NRCS Soil Survey included in our application, the soil within the proposed project area is classified as Type C, meaning the soil absorbs Stormwater Runoff the worst of the three soil classifications (Types A, B, and C). The higher rate of runoff leads to higher rates of erosion in this type of soil. If the SEF is permitted, SunShare will construct a detention pond, which will better mitigate the runoff and erosion onsite. 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. The subject property falls within a Federal Aviation Administration Airport Overlay Zone, specifically for the Greeley -Weld Airport.

The subject site is located north of country road 66 and west of country road 47. The proposed development is within parcel No. 080322300023 as identified per Weld County Property Portal. The subject parcel is approximately 71 acres. The site is bound to the south by parcels 080322300022 and 080322300003; to the east by parcel 080322000012; to the north by parcel 080322000018 and to the west by parcels 080322300001 and 080322300002. Currently the existing site does not have any regional detention or water quality features. The existing parcel has limited stormwater infrastructure. It is limited to surface drainage and driveway culverts. PROPOSED PROJECT The proposed PV arrays will provide approximately 332,350 square feet of PV panel area for solar power generation. The PV arrays will be pole mounted and ground disturbance under the panels will be minimal; thus, perviousness will be maintained under the solar cells allowing infiltration. Rainfall that lands on the angled PV panels will flow to the low side of the panel and discharge to the ground along the projected line of the panel low side. Concentration of flow is limited to the width of the PV panel, approximately 6.5 feet. Runoff then flows overland under the pole mounted PV panels matching existing flow patterns. Additional improvements proposed with this project are limited to a gravel & concrete drive which ties into the existing gravel drive on the property. This drive will serve as a permanent tracking pad for maintenance vehicle access. Furthermore, two small concrete distribution transformer pads will be located east and west of the existing gravel drive. No public access, stormsewer, or utility infrastructure improvements are anticipated at this time. After discussions with Weld County, a variance will be requested for County code section 8-11-40. Therefore, no detention & water quality will be provided for this project. Lytle Solar LLC — Drainage Report 1 SECTION 2 - HISTORIC DRAINAGE MAJOR DRAINAGE BASIN DESCRIPTION According to the FEMA Flood Insurance Rate Map Panel Number 08123C 1535E dated January 20th 2016, the site is not located within any flood zones. The property is outside the 100 -year and 500 -year floodplains so there is no risk of flooding onsite. Copies of the referenced flood map are included in the Appendix. SITE DRAINAGE AND EXISTING FACILITIES The site contains an existing gravel drive to an existing gas facility. Currently the existing site does not have any regional detention or water quality features. The existing site has limited stormwater infrastructure. It is limited to surface drainage and driveway culverts. Additionally, existing gas storage facilities are located on site along the center gravel drive. The remaining portions of the site are farmed agriculture. The proposed development area will be limited to a 42.11 acre section of the parcel. The site has a drainage divide near the center of the site breaking it into two drainage basins H -A & H -B. Historic basin H -A is sloped from east to west at a relative uniform 2.3% until it hits drainage swales running north -south on the east side of the gravel drive. The drainage from H -A then flows through two culverts under the existing gravel drive into an existing irrigation ditch until it flows south offsite. Historic basin H -B is generally slopes north to south at a relative uniform 0.4% until it spills offsite. Please refer to the Historic Drainage Map (FIG -1) for more information on existing drainage patterns. The soils located on the site are Nunn Lay Loam with a hydraulic soil rating of C, and Otero Sandy Loam rated A. The A soils are primarily located on the east portion or drainage basin H -A of the development area and the C soils are primarily located on the west portion of the development or drainage basin El -B. These classifications are given by the Natural Resources Conservation Service (NRCS) located in Appendix. Additionally, there are no known mapped wetlands located within the limits of the site or immediate drainage outfall area. Lytle Solar LLC — Drainage Report 2 SECTION 3 - PROPOSED (DEVELOPED) DRAINAGE DRAINAGE DESIGN CRITERIA The project is designed to comply with the Weld County Stormwater Design Standards and the Mile High Flood District's Urban Storm Drainage Criteria Manual (USDCM), 2007 Edition HYDROLOGIC METHOD AND DESIGN STORM FREQUENCIES The design rainfall one hour point rainfall used for the 10 -year and 100 -year storm events are 1.42 - inches and 2.72 inches, respectively. These values were taken from the National Oceanic and Atmospheric Administration's Atlas 14, Volume 8, Version 2 Point Precipitation Frequency Estimates. The Rational Method (Q=CIA) was used to determine the storm runoff (Q) from the areas contributing to the new storm system, with composite runoff coefficients (C) and contributing areas (A) given for design points in sub -basins. The runoff coefficients for various land usages were obtained from Table 6-5, USDCM, Vol. 1. Intensities (I) were determined using the Time - Intensity -Frequency equations, and a calculated Time of Concentration (te). Hydraulic Criteria. See Appendix for the runoff coefficient calculations. PROPOSED SITE DRAINAGE Impervious surface calculations were performed for the pre-existing and proposed development conditions. Due to the minimal concentration of flow and discharge to existing ground under the PV arrays, site imperviousness is relatively unaffected by the PV panels themselves. For the purposes of this study, solar panels were analyzed with a 25% impervious rate when above type C soils and 2% impervious when over type A soils as required by Weld County Code. All other impervious surface types utilize The Flood Control District's Urban Storm Drainage Criteria Manual Table 6-3 for recommended percentage imperviousness values. Developed Basin A is approximately 15.46 acres in size and corresponds directly with Historic Basin H -A. Improvements within Basin A consist of the solar arrays, gravel access drives, and small concrete pads for electrical equipment. Basin A consists of soils with a hydraulic soil rating A, therefore, imperviousness under the arrays will remain at 2%. The overall imperviousness for Basin A will increase from 3.2% to 3.5% compared to the historic basin. Runoff for the developed basin will be 4.18 cfs at the 10 -year event and 25.31 cfs at the 100 -year event. The increase in runoff compared to historic is only 0.06 cfs and 0.10 cfs at the 10 -year and 100 -year events. The increase in runoff is negligible and will not require detention. Lytle Solar LLC — Drainage Report 3 Developed Basin B is approximately 16.25 acres in size and corresponds directly with Historic Basin H -B. Improvements within Basin B consist of the solar arrays, gravel access drives, and small concrete pads for electrical equipment. Basin B consists of soils with a hydraulic soil rating C, therefore, imperviousness under the arrays will increase to 25% per code. The overall imperviousness for Basin B will increase from 2.0% to 7.8% compared to the historic basin. Runoff for the developed basin will be 3.48 cfs at the 1O -year event and 18.12 cfs at the 1OO-year event. The increase in runoff compared to historic is 0.85 cfs and 1.22 cfs at the 1O -year and 1OO- year events. Table 1— Site Imperviousness & Flow Rate Comparison H-A/A H-B/B TOTAL Area Impervious % 10-YR Flow Rates (CFS) 100-YR Flow Rates (CFS) Historic Developed Historic Developed Change Historic Developed Change 15.46 3.2 3.5 4.12 4.18 0.06 25.21 25.31 0.10 16.25 2.0 7.8 2.63 3.48 0.85 16.90 18.12 1.22 31.71 2.6 5.7 6.75 7.67 0.92 42.11 43.42 1.31 Detention for Basin A is not required. Basin consists primarily of hydraulic soil rating of A, and therefore, the imperviousness under the solar arrays will not be increased compared to historic conditions. The increase in developed runoff is negligible for Basin A. Runoff from basin A will flow offsite undetained as this runoff enters an existing irrigation ditch and flows south along the existing access road. After discussions with staff at Weld County, due to the low increase in imperviousness and flow rates on site, and all runoff will be directed within the same parcel, detention and water quality for Basin B will not be provided. A small diversion berm will be provided along the west property line to keep runoff on the owners developed parcel. The total basin imperviousness & resulting flow rates from pre-existing & post development is summarized in Table 1. Lytle Solar LLC — Drainage Report 4 STORMWATER MANAGEMENT PLAN Erosion control features will be installed at strategic locations on the site prior to construction activities. These features will include vehicle tracking control at the site construction entrances and silt fences, as part of the storrnwater management plan. Such measures will be included in the erosion control plan and detail sheets within the final construction documents. Lytle Solar LLC — Drainage Report 5 SECTION 4 - CONCLUSIONS This Drainage Report and attached drainage maps have been produced in accordance with the Weld County Stormwater Standards and Drainage Criteria and the Mile High Flood District's Urban Storm Drainage Criteria Manual (USDCM). Pursuant to Weld County's section 8-11-40 detention will be provided. Improvements proposed with this project are limited to a gravel -concrete drive, two small concrete distribution transformer pads, and pole -mounted photovoltaic arrays. No public access, storm sewer or utility infrastructure improvements are anticipated at this time. Proposed development will not alter historic drainage patterns and adjacent and downstream property owners and right of ways should not be affected.

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. e Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 6/7/2022 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.

The estimates are expressed in terms of micrometers per second. They are based on soil characteristics observed in the field, particularly structure, porosity, and texture. Saturated hydraulic conductivity is considered in the design of soil drainage systems and septic tank absorption fields. For each soil layer, this attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used. The numeric Ksat values have been grouped according to standard Ksat class limits.

The subject site is located north of country road 66 and west of country road 47. The proposed development is within parcel No. 080322300023 as identified per Weld County Property Portal. The subject parcel is approximately 71 acres. The site is bound to the south by parcels 080322300022 and 080322300003; to the east by parcel 080322000012; to the north by parcel 080322000018 and to the west by parcels 080322300001 and 080322300002. Currently the existing site does not have any regional detention or water quality features. The existing parcel has limited stormwater infrastructure. It is limited to surface drainage and driveway culverts. PROPOSED PROJECT The proposed PV arrays will provide approximately 332,350 square feet of PV panel area for solar power generation. The PV arrays will be pole mounted and ground disturbance under the panels will be minimal; thus, perviousness will be maintained under the solar cells allowing infiltration. Rainfall that lands on the angled PV panels will flow to the low side of the panel and discharge to the ground along the projected line of the panel low side. Concentration of flow is limited to the width of the PV panel, approximately 6.5 feet. Runoff then flows overland under the pole mounted PV panels matching existing flow patterns. Additional improvements proposed with this project are limited to a gravel & concrete drive which ties into the existing gravel drive on the property. This drive will serve as a permanent tracking pad for maintenance vehicle access. Furthermore, two small concrete distribution transformer pads will be located east and west of the existing gravel drive. No public access, stormsewer, or utility infrastructure improvements are anticipated at this time. Detention will be provided in the southwest corner of the site underneath the proposed solar arrays. Lytle Solar LLC — Drainage Report 1 SECTION 2 - HISTORIC DRAINAGE MAJOR DRAINAGE BASIN DESCRIPTION According to the FEMA Flood Insurance Rate Map Panel Number 08123C 1535E dated January 20th 2016, the site is not located within any flood zones. The property is outside the 100 -year and 500 -year floodplains so there is no risk of flooding onsite. Copies of the referenced flood map are included in the Appendix. SITE DRAINAGE AND EXISTING FACILITIES The site contains an existing gravel drive to an existing gas facility. Currently the existing site does not have any regional detention or water quality features. The existing site has limited stormwater infrastructure. It is limited to surface drainage and driveway culverts. Additionally, existing gas storage facilities are located on site along the center gravel drive. The remaining portions of the site are farmed agriculture. The proposed development area will be limited to a 42.11 acre section of the parcel. The site has a drainage divide near the center of the site breaking it into two drainage basins H -A & H -B. Historic basin H -A is sloped from east to west at a relative uniform 2.3% until it hits drainage swales running north -south on the east side of the gravel drive. The drainage from H -A then flows through two culverts under the existing gravel drive into an existing irrigation ditch until it flows south offsite. Historic basin H -B is generally slopes north to south at a relative uniform 0.4% until it spills offsite. Please refer to the Historic Drainage Map (FIG -1) for more information on existing drainage patterns. The soils located on the site are Nunn Lay Loam with a hydraulic soil rating of C, and Otero Sandy Loam rated A. The A soils are primarily located on the east portion or drainage basin H -A of the development area and the C soils are primarily located on the west portion of the development or drainage basin El -B. These classifications are given by the Natural Resources Conservation Service (NRCS) located in Appendix. Additionally, there are no known mapped wetlands located within the limits of the site or immediate drainage outfall area. Lytle Solar LLC — Drainage Report 2 SECTION 3 - PROPOSED (DEVELOPED) DRAINAGE DRAINAGE DESIGN CRITERIA The project is designed to comply with the Weld County Stormwater Design Standards and the Mile High Flood District's Urban Storm Drainage Criteria Manual (USDCM), 2007 Edition HYDROLOGIC METHOD AND DESIGN STORM FREQUENCIES The design rainfall one hour point rainfall used for the 10 -year and 100 -year storm events are 1.42 - inches and 2.72 inches, respectively. These values were taken from the National Oceanic and Atmospheric Administration's Atlas 14, Volume 8, Version 2 Point Precipitation Frequency Estimates. The Rational Method (Q=CIA) was used to determine the storm runoff (Q) from the areas contributing to the new storm system, with composite runoff coefficients (C) and contributing areas (A) given for design points in sub -basins. The runoff coefficients for various land usages were obtained from Table 6-5, USDCM, Vol. 1. Intensities (I) were determined using the Time - Intensity -Frequency equations, and a calculated Time of Concentration (te). Hydraulic Criteria. See Appendix for the runoff coefficient calculations. PROPOSED SITE DRAINAGE & DETENTION Impervious surface calculations were performed for the pre-existing and proposed development conditions. Due to the minimal concentration of flow and discharge to existing ground under the PV arrays, site imperviousness is relatively unaffected by the PV panels themselves. For the purposes of this study, solar panels were analyzed with a 25% impervious rate when above type C soils and 2% impervious when over type A soils as required by Weld County Code. All other impervious surface types utilize The Flood Control District's Urban Storm Drainage Criteria Manual Table 6-3 for recommended percentage imperviousness values. Developed Basin A is approximately 15.46 acres in size and corresponds directly with Historic Basin H -A. Improvements within Basin A consist of the solar arrays, gravel access drives, and small concrete pads for electrical equipment. Basin A consist of soils with a hydraulic soil rating A, therefore, imperviousness under the arrays will remain at 2%. The overall imperviousness for Basin A will increase from 3.2% to 3.5% compared to the historic basin. Runoff for the developed basin will be 4.18 cfs at the 10 -year event and 25.31 cfs at the 100 -year event. The increase in runoff compared to historic is only 0.06 cfs and 0.10 cfs at the 10 -year and 100 -year events. The increase in runoff is negligible and will not require detention. Lytle Solar LLC — Drainage Report 3 Developed Basin B is approximately 16.25 acres in size and corresponds directly with Historic Basin H -B. Improvements within Basin B consist of the solar arrays, gravel access drives, and small concrete pads for electrical equipment. Basin B consist of soils with a hydraulic soil rating C, therefore, imperviousness under the arrays will increase to 25% per code. The overall imperviousness for Basin B will increase from 2.0% to 7.8% compared to the historic basin. Runoff for the developed basin will be 3.48 cfs at the 1O -year event and 18.12 cfs at the 1OO-year event. The increase in runoff compared to historic is 0.85 cfs and 1.22 cfs at the 1O -year and 1OO- year events. Per Weld County code, detention will be provided for this developed condition. Table 1— Site Imperviousness & Flow Rate Comparison H -A/A H-B/B TOTAL Area Impervious % 10-YR Flow Rates (CFS) 100-YR Flow Rates (CFS) Historic .

Basin consists primarily of hydraulic soil rating of A, and therefore, the imperviousness under the solar arrays will not be increased compared to historic conditions. The increase in developed runoff is negligible for Basin A, however, the allowable release rate for the pond in Basin B will be reduced by O.1 cfs to account for the nominal increase in runoff from Basin A. Runoff from basin A will not be tributary to the detention basin and will flow offsite undetained as this runoff enters an existing irrigation ditch and flows south along the existing access road. Detention for Basin B has been provided in the southwest corner of the project to restrict runoff from the basin. Detention is sized for water quality and the 1OO-year event using the historic 1O - year runoff rate of drainage basin H -B. The allowable release rate for Pond B is 2.63 cfs to match historic 1O -year rate. However, the design release rate will be reduced to 2.53 cfs to provide additional detention to compensate for the increase in runoff of O.1O cfs produced in Basin A. The total basin imperviousness & resulting flow rates from pre-existing & post development is summarized in Table 1. Release rates for the Pond B detention will be controlled by a weir spillway with an orifice plate for the WQ event. The spillway will have a notch to control the 1OO-year event and a spillway above the 1OO-year WSE for emergency overflow. Final design will be provided with the Construction Documents. Lytle Solar LLC — Drainage Report 4 STORMWATER MANAGEMENT PLAN Erosion control features will be installed at strategic locations on the site prior to construction activities. These features will include vehicle tracking control at the site construction entrances and silt fences, as part of the storrnwater management plan. Such measures will be included in the erosion control plan and detail sheets within the final construction documents. Lytle Solar LLC — Drainage Report 5 SECTION 4 - CONCLUSIONS This Drainage Report and attached drainage maps have been produced in accordance with the Weld County Stormwater Standards and Drainage Criteria and the Mile High Flood District's Urban Storm Drainage Criteria Manual (USDCM). Pursuant to Weld County's section 8-11-40 detention will be provided. Improvements proposed with this project are limited to a gravel -concrete drive, two small concrete distribution transformer pads, and pole -mounted photovoltaic arrays and detention. No public access, storm sewer or utility infrastructure improvements are anticipated at this time. Proposed development will not alter historic drainage patterns and adjacent and downstream property owners and right of ways should not be affected.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

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. e Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 6/7/2022 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.

The intent of this Narrative is to provide traffic and construction related information and identify potential Project impacts to affected roadways within Weld County. The following information is included in this letter report: • Project Location, Components and Construction Schedule • Designated Travel Route • Daily Vehicle Trip Generation • Conclusions Project Location, Components and Construction Schedule Location - The Project is located on a +/- 80 acre leased area (within Weld County Parcel No. 080322300023), located east of the intersection of WCR 43 & WCR 66 in Section 22, Township 6N, Range 65W. Components - The Project generally includes: an initial Project of 5 MW solar energy conversion system comprised of 11,076 solar modules mounted on a tracker structure on shallow driven steel I -beams; concrete pad mounted transformer and interconnect; inverters mounted at the end of array rows; an access drive with emergency turn around; and perimeter fence with gate. Construction Schedule - It's currently anticipated that the Use by Special Review Permit will be issued by Weld County on or before January 2023. Accordingly, a construction start/mobilization date of March 2023 has been estimated, weather permitting. Based on this, the following preliminary schedule has been prepared, with Day 1 estimated to be March 1, 2023: • Solar Facility Components First Deliver • Perimeter Fence Installation • Solar Panel Foundation Installation • Racking, Trenching, Wiring • Solar Panel Installation Day 1 Day 1 to Day 11 Day 1 to Day 30 Day 30 to Day 64 Day 64 to Day 94 Nk,Nierat • 4> 1SunShare COMMUNITY SOLAR 1151 Bannock Street, Denver, CO 80204 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM • Inspection & Set Meters Day 94 to Day 99 • System Testing & Commissioning Day 99 to Day 109 Designated Travel Route The designated travel route includes: Interstate 25 north to 1-76 East to WCR 49 to WCR 66. The following is a brief description of the local access route roadways (i.e. WCR 49 and 66). We anticipate all project -related traffic will follow this route. Weld County Road (WCR) 49/47 — The 27.3 mile segment of WCR 49 included in the travel route is generally a +/-24' wide (per direction) asphalt paved road with a paved asphalt shoulder. There is sometimes a 12' center lane for turning. The posted speed limit is 55 mph in the vicinity of the Project site. The road surface appears to be in good condition and we do not anticipate our construction or regular traffic to impact road conditions or traffic congestion. Weld County Road (WCR) 66 — The ~1.6 mile segment of WCR 66 included in the travel route is generally a +/-24' wide asphalt paved road with varying gravel/soil shoulder width. The road surface appears to be in good condition. Construction and regular traffic associated with this project is not anticipated to impact road conditions or regular traffic flow. Daily Vehicle Trip Generation and Distribution Project development may be divided into the following 3 phases: material and equipment delivery; solar facility construction; and solar facility maintenance). The following Table 1 illustrates the estimated average daily trip generation by vehicle type for each Project phase.

This traffic will generally be site worker passenger vehicles. The majority of heavy truck traffic including conex container delivery (30-50 conex containers/delivery trucks) and equipment (rubber tire loader, pile driver, fork lift) delivery and pickup will travel to and from the Project between 8:00 AM and noon and 1:00PM and 4:30PM. Project related traffic during all phases will not be significant during AM and PM peak periods (7:30 - 9:00 AM and 4:30 - 6:00 PM, respectively). 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. Project installation is anticipated to begin in March 2023 (material and equipment delivery) and end in June 2023 (solar facility start-up and container and equipment container pick-up). The phase with the greatest amount of traffic (solar facility installation) is expected to occur over a 3 month period (March - June 2023). 3. Daily Project related truck traffic is not expected to impact AM and PM peak traffic periods. 4. As proposed, the solar facility installation (material/equipment delivery - approx.1 week, solar facility installation 3 months and solar facility operations - ongoing) is not anticipated to create adverse traffic related impacts on Weld County Roads. Based on anticipated vehicle type and weight (See Table 1), the project is not anticipated to degrade/damage Weld County roads.

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 3o years or more, with an opportunity for a life of so years or more with equipment replacement and repowering. At the end of the useful life of the facility, SunShare 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. 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. SunShare 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, SunShare 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 control BMPs will be applied during the decommissioning phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality. ■ Effectively, the decommissioning of the solar facility proceeds in reverse order of the installation: a. 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. io. 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, 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, SunShare 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 Clarifications — Inclusions and Exclusions $138,000.00 1.

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 of the site. This noxious weed management program was developed to prevent further spread of noxious weeds. SunShare 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: a.) 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. SunShare's operational staff will conduct regular site inspections and ensure 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: a.) 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; S.) Communication and coordination with adjacent land holders 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 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 (b) 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 e mergence, 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 e nvironment 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 e nvironmental hazards. This information will be evaluated for each herbicide considered for u se 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 according 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 (REI) 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.

SunShare is leasing this land from the Lytle Farms LLC, a Colorado limited Liability Company owned by Kaycee Lytle, a Weld County farmer and the Market President of the Bank of Colorado. This project is in the landowner and farmer's best interest, as noted in his letter attached in this application. Kaycee Lytle, owner of the parcel and the farmer of the land, owns one share of irrigation water, which is only about 10% of the water currently needed to completely irrigate the 80 -acre farm to its full potential. Lytle Farms is, essentially, almost completely reliant upon renting water, creating immense risk and vulnerability. Market rates also make the purchase of water (were it to even become available) wholly uneconomical as costs would far exceed any possible return on investment. The addition of the solar project reduces the amount of farmed land from 80 acres to 30-35, and the income generated from the solar lease payments has partially aided Lytle Farms in acquiring a subsurface drip irrigation system on the remaining 30 acres. In all, they will be reducing their water needs by 70%, and, due to the efficiency of the irrigation system, Kaycee believes their yields will only decrease by 25-30% (even though the land being farmed is decreasing by 50%). The revenues received from the solar project are much greater than the revenues the Lytle's generate from farming the same ground that the project will sit on, and the income generated will be used to pay for continued renovations to the farm, to grow their livestock operation, to reduce debt, and to further improve their agricultural activity onsite. While this parcel is zoned Agricultural, the land within the project boundary has Type C soil, which is the poorest soil type in terms of runoff and erosion prevention. The installation of the proposed SEF will include the addition of a detention pond, aiding in erosion mitigation. Additionally, this land does not possess water rights. The high cost of water makes this land quite expensive to farm, while the limited availability of water leads farming to be an unreliable venture for future use. No water will be required for a solar facility, leaving valuable water resources available for other Weld County farmers and ranchers. Additionally, this land houses several plugged and abandoned wells, batteries, and unused pipelines from former oil and gas operations, making it unsafe and unusable for residential or commercial developments. Solar is ultimately one of the few suitable uses for land near oil and gas infrastructure due to its lack of inhabitants. The project is not located within a residential neighborhood. 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • _._Shpre 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. SunShare is solely responsible for the management of all vegetation within our permitted area, and, rather than mowing, 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 our site pristine. Leasing the land for solar use provides another option for landowners to realize income from their property. Solar rental income provides the landowner with a stable, long-term, and steadily increasing income on their land, versus the variable income that results from unpredictable farming years and limited and expensive water. 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. SunShare develops solar facilities on land that produces 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.

SunShare is proposing a 5,000 kW AC (5,967 kW DC) SEF which will occupy approximately 31.7 acres on the northern half of the roughly 80 acre parcel. The current zoning on the parcel is Agricultural (A), however the landowner only possesses water rights for 10% of his water needs, and has Type C soil, which has a higher ability to erode. SunShare has executed a lease agreement with Lytle Farms. This 5,000 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. Noble Energy, Inc, has a battery and a well located within the project area, however the battery is actively being removed and the well is actively being plugged and abandoned. The proposed SEF abides by the necessary setbacks needed around the P+A well. We do not anticipate Noble will have an issue with this proposed plan as we have already held preliminary discussions with them regarding this project. All other 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. All oil and gas facility and pipeline owners have been identified and contacted. The landowners of adjacent parcels sharing borders with the project parcel have been notified, with the exception of one landowner due to a recent subdivision and acquisition (we Share COMMUNITY SOLAR 1151 Bannock Street, Denver, CO 80204 • info@mysunshare.com • 800.793.0786 • are sending a notification to these landowners as well). SunShare has received no known objections to date regarding this project. Please see the enclosed Buffer Report and Neighboring Landowner Notice Letters for details. SunShare will use an existing access for this SEF and will therefore not need to apply for an access permit. The access turns north off of WCR66, and is located approximately 0.36 miles east of the intersection of WCR 66 and WCR 43. This access road is presently used by Noble Energy Inc. for oil and gas operations and by the landowner, Lytle Farms LLC, for agricultural purposes. The road will be used for commercial purposes following the approval of the proposed SEF. Lytle Farms holds the access permit for this road, AP21-00049. The entrance to the site will include a 25' wide all-weather access driveway with two emergency hammerhead turnarounds (one at each equipment pad). 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 C, requiring the addition of a detention pond onsite to aid in runoff management. SunShare has included the detention pond details in its USR Sketch Plan Set. 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, T.100. This site currently houses a flood irrigation system for agricultural purposes. As evidenced by Kaycee Lytle, the landowner and farmer of the parcel, drip irrigation is both incredibly inefficient and incredibly costly as a means of irrigation for his crops. Once the SEF is installed, there will be no need for irrigation on that section of the parcel, and the remaining 30-35 acres of land will be farmed with a drip irrigation system (which Kaycee was able to fund partially with money from the solar lease). 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 up to 30 years, with a useful life of 35-40 years. Upon decommissioning, SunShare 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. SunShare will obtain all required permits and approvals, including utility interconnection agreements, prior to commencing construction. The project's engineers and general contractor will be made up of local experienced and 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. SunShare looks forward to working with Weld County to successfully complete this proposed development and bring the benefits of community solar energy to the County.

I am the owner of this parcel and wish the express my support for this project. I have been a resident of Weld County for 13 years; and I, along with my family, have farmed and lived on this land for 3 years. The farm was purchased from a developer who purchased the farm and immediately sold the water and mineral rights off of it. When we purchased it, it had been neglected for several years and was in tremendous disrepair. We have since renovated the original 1904 farmhouse and barn, have cleaned up the property and farm ground, and have brought livestock back on the farm for the first time in decades (according to neighbors). We believe we have returned this farm to a state that reflects its legacy, as well as Weld County's legacy as a whole. The addition of a solar garden will add even more to that legacy, representing Weld County's push towards new technologies and a well-balanced energy mix. This farm is our home and is special to our family. In fact, the proposed solar garden is named after my two daughters, Becca and Adlee. We have invited the solar project to our farm for three specific reasons: water, efficiency, and economics. We only own one share of irrigation water, which is only about 10% of the water needed to completely irrigate this 80 -acre farm to its full potential. We are essentially almost completely reliant upon renting water. This creates risk for us as depending on rental water leaves us in a vulnerable situation because we never know if we will find enough water to rent from one year to the next. Even if water became available to purchase (almost impossible due to demand from other farmers, developers and municipalities), the cost at today's market rates would exceed $500,000, completely uneconomical from a return -on -investment standpoint. We simply don't own enough water to farm 80 acres, and with the water demand pressures in our area due to population growth we do not see that changing. We have grown frustrated with the year-to-year uncertainty relating to renting water and feel that the solar project will help tremendously with this concern. With the addition of the solar project, we are reducing the amount of land needed to be irrigated to approximately 30-35 acres. On the remaining ground, we are fortunate to have been awarded a grant from the NRCS to install a subsurface drip irrigation system on the remaining 30 acres. In all, we will be reducing our water needs by 70%. And due to the efficiency of the irrigation system, we believe our yields will only decrease by 25-30% even though our land being farmed is decreasing by 50%. This is a tremendous benefit for us, and we are able to make this transition partly due to the revenue being generated by the solar project. Lastly, the economic benefit for our family is notable. The revenues received from the solar project are much greater than we generate from farming the same ground that the project will sit on. We will be able to use the earnings to pay for the irrigation project, to pay for continued renovations to the farm, to grow our livestock operation, and to reduce debt. We also hope that it will allow us to acquire more water for our farm if the opportunity presents itself. I interviewed 3 solar companies before selecting SunShare to partner on this project. I have been working with SunShare for the past year and I have confidence in their ability to deliver a safe and effective solar array. SunShare 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. SunShare 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 SunShare in invested in the project and will have continued high standards for site maintenance and land stewardship. This is especially important to me because I will be living on the farm next to the project. I understand that there is concern with taking agricultural land out of production for the development of a solar project. On my farm and in my location, for the reasons I discussed earlier plus many others, there simply isn't a better alternative than partnering on this solar project. This project will allow my family to continue honoring the land's agricultural heritage. I look forward to the development of this project and the continued relationship between myself, SunShare, and the County. Thank you for your time and consid o -A of this project. Sincerely, Kae Lytle Lytle Farms, LLC Hello
