Describe the proposed fire protection measures. o The Project is located within the Eaton Fire Protection District. The Project will comply with all Colorado Public Utilities Commission requirements as well as national codes and standards for construction, electrical, and fire. A supervisory control and data acquisition (SCADA) system will remotely monitor and control the Project 24 hours per day. The SCADA system will transmit Project data and control signals over the internet. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. o The Project is consistent with the Weld County Comprehensive Plan because it: i. Respects private property rights by allowing the owner of the property to do what is in their best interest while complying with local regulations and not interfering with or infringing upon the rights of others. ii. Promotes economic growth and stability by providing a diversified source of income for the landowner, the shepherd, and the County while also offering local residents the opportunity to save money on their electricity bills through Xcel's Solar*Rewards Community Program. iii. Protects the health, safety, and general welfare of the citizens of the County by providing an emission -free source of energy. iv. Is harmonious with surrounding agricultural and industrial uses. v. Supports future mineral development by reserving space on the landowner's property where minerals can be extracted in the future. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) o There are no water rights associated with the property, so crop production has become increasingly more challenging for this parcel. The new solar development will also not interfere with any of the surrounding agricultural land uses. The Project's array will protect the land underneath and in turn allow the soil to revitalize over time, therefore preserving the land to be used for agricultural purposes in the future, if desired. We will be planting a native seed mixture on the property that will not require irrigation. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. o The Project will be located within the Town of Eaton's Intergovernmental agreement area. o According to the Town of Eaton's Comprehensive Plan, the parcel containing the Project Area is in both the Urban Core Area as well as the Comprehensive Plan and Urban Growth Area, with the actual Project Area residing mainly in the (970) 425-3175 I INFO©CLOUDBREAKENERGY.COM I CLOUDBREAKENERGY.COM CLOUDBREAK PAGE 6 Urban Growth Area. Therefore, the proposed solar development aligns with the Town's future plans and will help satisfy a myriad of objectives for desired development set forth in the Town of Eaton's Comprehensive Plan. o As described in the Environmental Goals and Policies section within the Town of Eaton's Comprehensive Plan, Air Quality Goal 4.2 is to "implement measures to ensure that Eaton is working towards improving regional air quality" including ensuring "that new industry is non-polluting and that existing industries comply with the standards established in the Clean Air Act." Additionally, Goal 4 within the Economic Development section is to "encourage desirable non-polluting industrial development" and goal 5 is to "invest in the image of industrial and commercial areas to demonstrate the Town's dedication to providing quality opportunities to potential businesses." By establishing a solar energy project within the Town's Urban Growth Area, Eaton will be able to pursue the aforementioned goals and more. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. o The Project is not anticipated to impact the health, safety, or welfare of Weld County citizens. Designs will comply with Colorado Public Utilities Commission requirements as well as national codes and standards for construction, electrical, and fire. A supervisory control and data acquisition (SCADA) system will remotely monitor and control the Project 24 hours per day. The SCADA system will transmit Project data and control signals over the internet. 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. o There is no irrigation system on the property and there are no existing water rights. Due to this land being identified as non -irrigated dry farmland, it will not be taking prime agricultural land out of production. We will be planting a native seed mixture on the property and grazing sheep to maintain the vegetation at a height of no more than 18-22 inches. 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. o Flood Hazard, Geologic Hazard, Airport, and Historic Townsites: The Project is not located within any flood zones. According to the Colorado Geological Survey, no geologic hazards were identified within the Project Area. The Project is not within an Airport Overlay District. The Weld County property portal's (970) 425-3175 I INFO©CLOUDBREAKENERGY.COM I CLOUDBREAKENERGY.COM CLOUDBREAK PAGE 7 Historic Townsite layer showed no presence of historic sites within the Project Area. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. o There are no Federal permits required for the Project. o There are two State permits that may be required - the Colorado Department of Public Health and Environment Construction Stormwater Discharge Permit and the Colorado Department of Public Health and Environment Air Permit. No applications for State permits have been submitted.

This search included hundreds, if not thousands, of properties within Weld County. The Harring's property was chosen due to several factors including, but not limited to: • Close proximity to high quality Xcel Energy distribution infrastructure that has the capacity for a project of this size • Close proximity to Xcel Energy's Eaton substation, which is one of Xcel's preferred locations for interconnecting solar projects • Outside of floodplains and wetlands • Relatively flat • No geotechnical constraints • Landowner participation • Limited disturbance to nearby properties and property owners Alternatives to the Harring's property were thoroughly evaluated but were ultimately dismissed due to at least one of the above factors. The proposed Project presents the most viable design and location with the least adverse impacts of all the alternatives. Xcel Energy awarded CBEP Solar 6, LLC this project in December of 2020.

NOT FOR PERMITTING, BIDDING, NOR CONSTRUCTION. Prepared by or under the Direct Supervision of: Kelsey Blaisdell, P.E. 49698 "9/28/2022" Cloudbreak Energy is pursuing the development of the Harring project, a photovoltaic energy generation facility at a 36.25 -acre site located approximately 11 miles north of Garden City, Colorado, alongside County Road 76 (See Appendix A -Site Plans C-301, C-302, C-303 & C-304). The existing site is currently used for agricultural purposes with approximately 2.5% slopes. This drainage study was prepared to summarize findings from performing a hydrologic analysis of the project site to identify the potential stormwater impact from the proposed solar project and develop appropriate drainage best management practices (BMPs) to address the impact. This drainage study was prepared to comply with the Weld County Engineering and Construction Criteria (WCECC) Manual Requirements, updated January 2021. Proposed Project The proposed solar project will consist of pole mounted photovoltaic (PV) arrays. Ground disturbance under the panels will be minimal; thus, the existing perviousness of the soil will be maintained under the solar cells allowing infiltration. Rainfall runoff from the panels will not be concentrated and flow under the pole mounted PV panels matching the pre - development flow patterns. Additional improvements associated with this project are limited to gravel drives for vehicle access and concrete pads for distribution transformers (see Appendix A — Site Plans C-301, C-302, C-303 & C-304). No public access or utility infrastructure improvements are anticipated at this time. Site Drainage Currently, the existing site does not have any regional retention or water quality features. The soils in the area consist of hydrologic soil groups (HSG) A and C soils given by the Natural Resources Conservation Service (NRCS — Appendix B). Two drainage basins Labeled Drainage Area A and Drainage Area B have been identified for the site, with approximate areas of 6.89 acres and 26.17 acres respectively. Any offsite flows appear to follow the existing ditches and streams and are not expected to affect the project site. See Appendix A for the drainage area maps and details. A hydrologic analysis was prepared using the Rational Method based on requirements from the WCECC Manual. The analysis provided estimated peak flow rates for the 100 -year storm under both pre -and post -development conditions. The design rainfall depth for a 1 -hour, Stormwater Drainage Study 100 -year storm is 2.73 inches based upon NOAA Atlas 14: Precipitation -Frequency Atlas. The Rational Method equation shown below was used to determine the peak flow rates from Drainage Area A, Drainage Area B, Drainage Area C, and Drainage Area D. Existing conditions were determined to be "Greenbelt, Agriculture" which correlated to a 2% impervious value according to Table 5-2, Weld County Engineering and Construction Criteria. In Table 5-3 —Table 5-5, based on the soil type and impervious percentage, the runoff calculation for Drainage Area A is 0.49 and Drainage Area B is 0.30. Proposed conditions were determined to be the weighted average of "Greenbelt, Agriculture" (2% impervious), "Solar Facilities A&B" (2% impervious), and "Solar Facilities C&D Soils" (25% impervious). Using the same process as before, the runoff coefficients were weighted to be 0.53 and 0.32, for Drainage Area A and Drainage Area B, respectively. The drainage area imperviousness and resulting peak flow rates from pre -and post -development conditions are summarized below. See Appendix C for the runoff coefficient calculations. Q Q=C*I*A Where: — Runoff flow rate, in cubic feet per second (cfs) I — Rainfall Intensity, in inches per hour (in/hr) A — Area of the basin, in acres (ac) Pre -development Runoff Calculation Parameters Drainage Area Area, A (ac) Weighted Coefficient, Runoff C Rainfall Intensity, (in/hr) A 6.89 0.49 6.17 B 26.17 0.30 5.47 Post -development Runoff Calculation Parameters Drainage Area Area, A (ac) Weighted Coefficient, Runoff C Intensity, Rainfall (in/hr) I % Added area ac/total (impervious Impervious ac) A 6.89 0.53 6.17 4.64 B 26.17 0.32 5.47 0.26 100 -year Runoff Calculation Results Drainage Area Pre -development Peak Flow (cfs) Rate Post Peak -development Flow (cfs) Rate DIFFERENCE (cfs) A 20.95 22.74 1.79 B 43.38 45.65 2.27 Stormwater Drainage Study Based on the above results, the increase of impervious area would produce little increase (4.9%) in the peak flow rate. Because of this, a detention basin facility will not be proposed. Instead, two grass swales will be introduced, one near the southwest site boundary of Drainage Area A and another near the south site boundary of Drainage Area B, to dissipate energy and attenuate any potential flow increase from gravel roads and concrete pads. Erosion Control/Stormwater Management Plan Erosion control features such as silt fences and grass swales (also mentioned above) will be installed on the site prior to construction activities. Such measures will be included in the erosion control plan and detail sheets within the final construction documents. Grass swale sizing calculations are summarized in Appendix D. Conclusion The drainage study and attached drainage maps were produced in accordance with requirements from Weld County Engineering and Construction Criteria Manual, updated January 2021. The existing stormwater flow characteristics are expected to remain unchanged and increases in peak flow rates have been proven to be negligible. A basin type of stormwater detention would not be necessary. Improvements proposed with the project site are limited to a gravel paved drive and a small concrete distribution transformer pad. No public access or utility infrastructure improvements are anticipated at this time. The proposed development will not alter historic drainage patterns or adjacent and downstream property owners.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. e Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 3/3/2022 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part HARRING_DA_C_SOILREPORT Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.

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 3/3/2022 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part HARRING_DA_D_SOILREPORT Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.

The Environmental Protection Agency (EPA) sets forth the National Ambient Air Quality Standards (NAAQs) pursuant to the Clean Air Act. Air quality impacts associated with construction projects generally arise from fugitive dust generation during the operation of heavy equipment. Colorado administers the NAAQS through issuance of the Air Pollutant Emission Notice (APEN). The Project will not exceed the NAAQS and will follow best management practices to ensure that the production of dust will be controlled by the regular application of water to the Project. The Project will obtain an APEN permit prior to construction. Minimal dust is expected to be generated during construction and operations due to the planned use of dust suppression best management practices and soil stabilization following construction and throughout operations. During construction, CBEP Solar 6, LLC and its contractors will control dust by applying water to disturbed soils and soil piles to control fugitive dust from blowing and impairing air quality. Once the construction phase is completed, the site will be visited 1-2 times per year for routine maintenance and as needed for emergency maintenance. Disturbed areas not covered with gravel as part of the Project design will be reseeded with a diversified seed mixture to revegetate disturbed areas and hold soil in place, minimizing fugitive dust impacts during operations. CBEP Solar 6, LLC would employ native revegetation methods or chemical control methods for infestations of weeds during regular maintenance if necessary.

During construction, CBEP Solar 6, LLC and its contractors will control dust by applying water to disturbed soils and soil piles to control fugitive dust from blowing and impairing air quality. • During the operations of the Project, the land under and around the Project will be seeded with a diversified seed mixture, which will mitigate dust. Weed Control: • Once construction is complete, CBEP Solar 6, LLC plans to work with Pawnee Buttes/Greencover to create a unique diversified seed mixture to be seeded within the Project Area and will utilize sheep grazing to maintain the land. The site will be inspected annually by CBEP Solar 6, LLC or its contractors for the presence of invasive species. Minor presences will be managed by cutting and pulling in a manner to not disburse or promote spreading of weed seeds. If a major presence occurs, mowing and the potential application of herbicides will be deployed. Herbicide selection may vary depending on the time of year, the life cycle of the noxious weed species, and preferences of the shepherd and the landowner.

The Project is located near Eaton, Weld County, Colorado. Figure 1 demonstrates the proposed PV array location for the Project. Solar Glare Analysis Methodology TRC conducted a solar glare analysis using methodology developed by Sandia National Laboratories and described in the Solar Glare Hazard Analysis Tool (SGHAT) User's Manual (Ho et al, 2013). The SGHAT-compliant software used in this analysis is under license to TRC by ForgeSolar. Under certain conditions, solar panel surfaces reflect sunlight and produce glint (a momentary flash of bright light) or glare (a continuous source of bright light). Magnitude of glint and glare depends on several factors such as sun position, location of observer, and characteristics of the solar PV array including the tilt, orientation, location, and optical properties of the modules. Glare visibility from the observer's location is analyzed once glare characteristics are determined. Ocular hazard potential is estimated based on retinal irradiance and subtended angle (size/distance) of the glare (Ho et al., 2010). Potential ocular hazards range from temporary after -image to retinal burn depending on the retinal irradiance and subtended angle as shown in Figure 2. The SGHAT classifies solar glare into three categories, denoted as either `green', `yellow', or 'red' glare. • Green glare is the mildest of the three glare classifications and refers to a level of glare that has a low potential to cause after -image and no potential to cause retinal burn. • Yellow glare is a moderate level of glare with some potential to cause temporary after- image and no potential to cause retinal burn. • Red glare is a serious and significant form of glare with potential to cause retinal burn and/or permanent eye damage. \\madison-vfp\Records\-\WPMSN\PJT2\434718\0000\000024\M4347180000PH24-003.docx Technical Memorandum Page 2 of 5 Limitations of the SGHAT applicable to this Project are as follows: • The SGHAT does not rigorously represent the detailed geometry of a solar panel array; detailed features such as gaps between modules, variable height of the PV array, and support structures may impact actual glare results. However, accuracy of the current approach is validated by several test cases. • The model does not consider obstacles (either man-made or natural, existing, or proposed) and mitigation measures between the observation points and prescribed solar installation that may obstruct predicted glare. • The ocular hazard predicted by the tool depends on a number of environmental, optical, and human factors, which can be uncertain. In general, default values given by the SGHAT in this analysis reflect the worst -case scenario. As such, the actual glare created by the proposed Project will likely be less than that predicted by this model. Project Description Preliminary layout and panel configuration have been developed by Cloudbreak. As the Project is further designed, it is likely that the actual Project footprint will be smaller than that used for this analysis. Figure 1 depicts the proposed array area, observation points (OPs) and route receptors evaluated. Project Specifications The PV panels for the Project are proposed to be mounted on a single axis tracking racking system with axes that are oriented to the south (180° azimuth), and an east -west tilt angle of 52° to - 52°. The resting angle, which is defined as the angle of rotation of the panels when the sun is outside the panels' tracking range, is proposed to be 0°. Single -axis tracking systems are programmed for the panels to remain perpendicular to the sun's location as the sun moves across the sky throughout the day via solar data from ephemeris tables, which predict the sun's path across the sky. The tracking system begins when the sun's location is perpendicular with the maximum tracking angle (52°) of the system and continues until the sun enters a range where the panel can no longer remain perpendicular with the sun. When the sun is outside the tracking range of the system (when the panels no longer can remain perpendicular with the sun), the trackers remain at their resting angle or utilize backtracking. The Project will utilize backtracking at the site to reduce the impacts from shading during the morning and evening hours of the day. ForgeSolar utilizes four methods to model backtracking which include "shade -slope," "shade," "interval," and "instant." Because the site is not located on flat ground and the primary goal of the backtracking is to minimize impacts to the system from shading, a "shade -slope" method was utilized in this model. "Shade -slope" is a slope aware method design to accommodate the modules placed on arbitrarily -oriented slopes and reduce shading. For the backtracking analysis, a ground coverage ratio of 40.1 percent was assumed. The panels are proposed to be mounted to the racking at approximately 4.5 -feet (54 inches) above ground level (AGL). The glare analysis will be evaluated at the mounting height. No significant grading is currently proposed for the Project. The panels are designed to absorb \\madison-vfp\Records\-1WPMSN\PJT2\434718\0000\000024\M4347180000PH24-003.docx Technical Memorandum Page 3 of 5 sunlight. The panels were modeled as smooth glass. The panels will be treated with anti - reflective coatings (ARC), which assists to absorb and transmit light rather than reflecting it. Observation Point Parameters Solar glare hazard analyses were conducted for selected residences located in vicinity of the Project using ForgeSolar's OP tool to estimate potential glare. Unoccupied structures, such as garages, sheds, barns, etc., were not analyzed. The OPs analyzed were selected by TRC. A height of 6 feet was used to represent observers located at one-story residences/buildings. A height of 16 feet was used to represent observes located on the second floor of two-story residences/buildings. For bi-level residences, heights of 3 feet at 12 feet are assumed for the lower and upper floors, respectively. Table 1 summarizes the modelled characteristics of the selected OPs and their corresponding labels. Figure 1 shows the locations of the selected OPs in relation to the Project. Table 1: Observation Points Observation Point Label Number of Floors in Residence Height (ft) OP1 One-story residence at 19188 County Road 76 6 OP2 Two-story residence at 19186 County Road 76 6 16 OP3 OP4 One-story residence at 19184 County Road 76 6 OP5 Bi-Level residence at 19180 County Road 76 3 OP6 12 OP7 Two-story residence at 19442 County Road 76 6 16 OP8 OP9 Two-story residence at 36648 County Road 39 6 16 OP10 OP11 Two-story residence at 36788 County Road 39 6 16 OP12 OP13 One-story residence at 19154 County Road 76 6 Route Receptors TRC also analyzed the adjacent roadways, County Road 39 and County Road 76, utilizing the Route Receptor in ForgeSolar (Figure 1). The Route Receptor provides a multi -line representation that simulates observers traveling along continuous paths such as roads, railways, helicopter paths, and multi -segment flight tracks. The viewing angle for observers traveling within passenger vehicles along the roadways was presumed to be a 180° field of view, which represents that the observer can view glare in all directions. A viewing angle of 50° was used for commercial vehicles to account for the restricted field of view of larger commercial vehicles. A height of 5 feet was assumed for passenger vehicles and 11 feet for commercial vehicles. It was assumed that only passenger vehicles used the residential section of County Road 76. \\madison-vfp\Records\-\WPMSN\PJT2\434718\0000\000024\M4347180000PH24-003.docx Technical Memorandum Page 4 of 5 Additional Assumptions The following assumptions have been utilized for the analyses: • Time zone for the Project was set at UTC — 7 hours (Mountain Standard Time). • Subtended angle of the sun of 9.3 milliradian (mrad) is assumed as recommended by SGHAT. This is the average angle of the sun as viewed from earth as it moves throughout the day. • The time interval for the analysis was set to run at 1 -minute increments. Inputs, outputs, and other assumptions used in the analysis are documented in Attachment 1. Results, Recommendations, and Conclusions TRC conducted the solar glare hazard analysis using the FAA -approved SGHAT tool to evaluate potential impact of the Project on the evaluated OPs and Route Receptors. TRC evaluated the potential solar glare impact of the PV panels using the project specifications detailed above. Table 2 summarizes the estimated total number of minutes per year that glare may be visible from the proposed Project at each OP and Route Receptor evaluated. These results are detailed in Attachment 1.

However, yellow glare is modelled to be observed at OP7, OP8, OP10, and OP12 and along County Road 39 and County Road 76. It should be noted that the modeled backtracking in ForgeSolar is not exactly the same as the backtracking that may be used on -site during operations. The estimated glare that may be visible at the evaluated receptors is described below. • OP7 and OP8 are located approximately 150 feet east of the array area. OP7 was modelled on the first floor and OP8 was modelled on the second floor of the evaluated residence. Yellow glare may be visible at both observation points for less than 10 minutes per day from approximately 4:30 pm to 5:00 pm from early February to early November at OP7 and from 4:00 pm to 10:00 pm throughout the year at OP8. • OP9 and OP10 are located approximately 1,250 feet west of the array area. OP9 was modelled on the first floor and OP10 was on the second floor of the evaluated residence. Yellow glare may be visible at both receptor locations for less than 10 minutes per day from approximately 4:00 am to 8:00 am throughout the year. • OP11 and OP12 are located approximately 1,290 feet northwest of the array area. OP11 was modelled on the first floor and OP12 was on the second floor of the evaluated residence. Yellow glare may be visible at both receptor locations for less than 10 minutes per day from approximately 6:00 am to 8:00 am from October to early March. • County Road 39 is located west of the array area. Yellow glare may be visible for less than 10 minutes a day from approximately 4:30 am to 8:00 am throughout the year from a passenger car traveling along the evaluated section of County Road 39. Cloudbreak is evaluating several methods to mitigate the glare estimated to be visible at the above receptors. These methods include the use of vegetative screening or changes in the project specifications. Due to the amount of glare observed from upper floors of the adjacent properties, vegetative screening may not be as applicable to the site. Adjusting the resting angle of the system would also mitigate the modelled glare. At a resting angle of approximately 5 degrees, the modelled glare is expected to be reduced to zero minutes a year. This is because the resting angle of a tracking system, and at the end of the backtracking range, can have a large impact on glare produced near sunrise and sunset. When the sun is low on the horizon, an angle (even a slight angle) is needed to reflect light in a more upward trajectory, minimizing the light reflected to observers close to the ground. It should be noted that changes to the Project specifications may affect the results of this analysis. References Ho, C.K., C.M. Ghanbari, and R.B. Driver. 2010.

Figure 2. Glare Hazard Analysis Plot and FAA Acceptable Glare Limits (Ho et at, 2011 and FAA, 2013) Glare analyses do not account for physical obstructions between reflectors and receptors. This includes buildings, tree cover and geographic obstructions. Several calculations utilize the PV array centroid, rather than the actual glare spot location, due to algorithm limitations. This may affect results for large PV footprints. Additional analyses of array sub -sections can provide additional information on expected glare. The subtended source angle (glare spot size) is constrained by the PV array footprint size. Partitioning large arrays into smaller sections will reduce the maximum potential subtended angle, potentially impacting results if actual glare spots are larger than the sub -array size. Additional analyses of the combined area of adjacent sub -arrays can provide more information on potential glare hazards. (See previous point on related limitations.) Glare locations displayed on receptor plots are approximate. Actual glare -spot locations may differ. Glare vector plots are simplified representations of analysis data. Actual glare emanations and results may differ. The glare hazard determination relies on several approximations including observer eye characteristics, angle of view, and typical blink response time. Actual results and glare occurrence may differ. Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid based on aggregated research data. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum. 2016-2019 © Sims Industries d/b/a ForgeSolar, All Rights Reserved. \\madison-vfp\Records\-\WPMSN\PJT2\434718\0000\000024\M4347180000PH24-003.docx Attachment 1 Harring Solar Project Solar Glare Hazard Analysis Reports 11madison-vfp\Records\-1WPMSN\PJT21434718100001000024\M4347180000PH24-003.docx ■N.■■ Forge Rv planning & glare analysis • FORGESOLAR GLARE ANALYSIS Project: Harring Solar An approximately 5 MW solar project located outside of Eaton, Colorado.

"Yellow" glare is glare with potential to cause an after -image ( ash blindness) when observed prior to a typical blink response time. Times associated with glare are denoted in Standard time. For Daylight Savings, add one hour. Glare analyses do not account for physical obstructions between re ectors and receptors. This includes buildings, tree cover and geographic obstructions. Several calculations utilize the PV array centroid, rather than the actual glare spot location, due to V1 algorithm limitations. This may a ect results for large PV footprints. Additional analyses of array sub -sections can provide additional information on expected glare. The subtended source angle (glare spot size) is constrained by the PV array footprint size. Partitioning large arrays into smaller sections will reduce the maximum potential subtended angle, potentially impacting results if actual glare spots are larger than the sub -array size. Additional analyses of the combined area of adjacent sub -arrays can provide more information on potential glare hazards. (See previous point on related limitations.) Glare locations displayed on receptor plots are approximate. Actual glare -spot locations may di er. Glare vector plots are simpli ed representations of analysis data. Actual glare emanations and results may di er. The glare hazard determination relies on several approximations including observer eye characteristics, angle of view, and typical blink response time. Actual results and glare occurrence may di er. Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid based on aggregated research data. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum.

The Project includes construction of 4.625 Megawatts (MW) of solar electric generation on a 69.96 -acre parcel. This Lighting Plan describes lighting during the construction and operations phases of the Project. Temporary Construction Lighting: The need for lighting during construction is expected to be limited because the majority of construction activities will occur during daylight hours. If lighting is needed during construction, lights will be positioned and/or shielded from oncoming traffic and residences in the vicinity of the project site, as necessary. Cutoff -type luminaires would be used where practicable. Individual light sources would not exceed 150,000 lumens per light source (typical of a 1250W metal halide light) and would project 0.1 lumen or less at property lines. Unnecessary lighting will not be used. Lights would not exceed 24 feet in height. Any lighting needed for construction is not shown in the dimensioned elevation drawing of the USR Map due to its temporary nature. Project Operations Lighting: There will be no lighting on the Project after construction is completed.

The Project includes construction of 5 Megawatts (MW) of solar electric generation on a 32.5 -acre parcel. The purpose of this noise study was to determine the level of noise impact the Project at nearby residences and to ensure that the Project complies with state and county regulations. The level of impact has been determined based on The State of Colorado Noise Law and WCC Chapter 14 Article 9 (Noise). Fundamentals of Noise Noise can be defined as unwanted sound. When a noise is distinctly louder than the ambient noise environment and reaches a certain level, it can disrupt normal activities. The magnitude of noise or the deviation from the ambient noise level is usually described by sound pressure. The magnitude of noise is usually described by a ratio of its sound pressure to a reference sound pressure, which is usually 20 micro - Pascals. A logarithmic scale is used to relate sound pressure to a common reference pressure, yielding the sound pressure level (SPL). SPL is measured in dimensionless units of decibels (dB) and are modified by frequency response of human hearing or weighting. The commonly accepted limits of human hearing to detect sound are between the threshold of hearing at 0 dB and the threshold of pain at 140 dB. Sound frequencies are represented in units of Hertz (Hz), which correspond to the number of vibrations per second of a given tone. Sound occurs over a wide range of frequencies. Three weightings have been established for measuring sound pressure: A, B, and C. The commonly accepted audible frequency is between 20 Hz and 20,000 Hz, and human hearing is most sensitive to the frequencies between 1,000 Hz and 6,000 Hz. The A -weighted scale is adjusted to frequencies most sensitive to human ears. Sound levels that are measured using the A -weighted scale are often expressed as dB(A). All noise levels in this noise impact analysis report will be expressed in dB(A). A key concept in evaluating potential noise impacts is the perceived effect of incremental increases in existing noise levels. Changes in dB(A) are exponential; therefore, an increase of 3 dB(A) is barely perceptible, an increase of 5 dB(A) is readily perceptible, and a 10 dB(A) increase would be perceived by someone to be a doubling of the noise level (loudness). Existing Noise Environment: The subject site is located southeast of the intersection of County Road 76 and County Road 39 in an unincorporated area of Weld County, Colorado. The Project Area is surrounded by existing agricultural fields to the west, south, and east; and a residential area to the north. The applicable setbacks from adjacent property lines, and roadways, will be required and much of the existing vegetation (if present) within the setbacks will be retained. Existing noise sources at the site occur mainly from infrequent vehicular traffic traveling on nearby roadways. 1 i Tr�C Noise Study Harring Solar Project Weld County, Colorado State of Colorado Noise Law Colorado Revised Statutes 25-12-103: Maximum Permissible Noise Levels. 1.

Temporary noise impacts during construction would occur during daylight hours while construction equipment is being operated including, but not limited to, passenger vehicles, earthmoving equipment, concrete mixers, water trucks, and semi-tractor/trailer trucks. The spatial distribution of construction noise emissions would vary during the day and depend upon the type of activity. Construction traffic will generate noise along the haul route. This noise would be temporary during commuting hours and when supplies are delivered over the course of construction. Operations Sources of noise during operation would only include temporary vehicle noise from maintenance personnel access and typical noise emissions from the solar array, inverters (which convert electricity from AC -to -DC, and DC -to -AC), transformers (which "step up" and "step down" the system voltage), and overhead transmission. Project facilities that emit sound during operation include inverters. Noise emission from inverters depends on the inverter model and number of inverters, which will be determined based on detailed engineering to be completed during final design and approval of the site, but typical emissions from industrial PV inverters and associated supporting equipment utilized in previous solar projects within the region range from 48 to 72 dB(A) at a distance of 10 feet (Tech Environmental 2012). Within this range, inverter sound levels are generally 3 i TRC Noise Study Harring Solar Project Weld County, Colorado indistinguishable from background noise levels at a distance of 150 feet from the inverter (Tech Environmental 2012). Typical equipment that is expected to be utilized for this Project includes Module Model LONGi LR4- 72NHD-435M or similar and Inverter Model CPS SCH125KTL-DO/US-600 or similar. For comparison, a gas lawnmower can produce around 90 dB(A), a vacuum cleaner around 70 dB(A), and a dishwasher in the next room around 50 dB(A) (FAA 2022). Based on the typical sound levels from Project operation and the distance to the boundary, the Project will adhere to Weld County and State of Colorado permissible noise levels. Conclusion The purpose of this noise study was to determine the level of noise impact the Project will produce and ensure that the Project will comply with state and county regulations. This level of impact has been determined based on the Weld County noise regulations. Based on typical solar energy facility equipment, it is expected that the noise levels from Project facilities will meet the Weld County Noise Ordinance and state statute requirements.

NOT FOR PERMITTING, BIDDING, NOR CONSTRUCTION. Prepared by or under the Direct Supervision of: Kelsey Blaisdell, P.E. 49698 "9/28/2022" Cloudbreak Energy is pursuing the development of the Harring project, a photovoltaic energy generation facility at a 36.25 -acre site located approximately 11 miles north of Garden City, Colorado, alongside County Road 76 (See Appendix A -Site Plans C-301, C-302, C-303 & C-304). The existing site is currently used for agricultural purposes with approximately 2.5% slopes. This drainage study was prepared to summarize findings from performing a hydrologic analysis of the project site to identify the potential stormwater impact from the proposed solar project and develop appropriate drainage best management practices (BMPs) to address the impact. This drainage study was prepared to comply with the Weld County Engineering and Construction Criteria (WCECC) Manual Requirements, updated January 2021. Proposed Project The proposed solar project will consist of pole mounted photovoltaic (PV) arrays. Ground disturbance under the panels will be minimal; thus, the existing perviousness of the soil will be maintained under the solar cells allowing infiltration. Rainfall runoff from the panels will not be concentrated and flow under the pole mounted PV panels matching the pre - development flow patterns. Additional improvements associated with this project are limited to gravel drives for vehicle access and concrete pads for distribution transformers (see Appendix A — Site Plans C-301, C-302, C-303 & C-304). No public access or utility infrastructure improvements are anticipated at this time. Site Drainage Currently, the existing site does not have any regional retention or water quality features. The soils in the area consist of hydrologic soil groups (HSG) A and C soils given by the Natural Resources Conservation Service (NRCS — Appendix B). Two drainage basins Labeled Drainage Area A and Drainage Area B have been identified for the site, with approximate areas of 6.89 acres and 26.17 acres respectively. Any offsite flows appear to follow the existing ditches and streams and are not expected to affect the project site. See Appendix A for the drainage area maps and details. A hydrologic analysis was prepared using the Rational Method based on requirements from the WCECC Manual. The analysis provided estimated peak flow rates for the 100 -year storm under both pre -and post -development conditions. The design rainfall depth for a 1 -hour, Stormwater Drainage Study 100 -year storm is 2.73 inches based upon NOAA Atlas 14: Precipitation -Frequency Atlas. The Rational Method equation shown below was used to determine the peak flow rates from Drainage Area A, Drainage Area B, Drainage Area C, and Drainage Area D. Existing conditions were determined to be "Greenbelt, Agriculture" which correlated to a 2% impervious value according to Table 5-2, Weld County Engineering and Construction Criteria. In Table 5-3 —Table 5-5, based on the soil type and impervious percentage, the runoff calculation for Drainage Area A is 0.49 and Drainage Area B is 0.30. Proposed conditions were determined to be the weighted average of "Greenbelt, Agriculture" (2% impervious), "Solar Facilities A&B" (2% impervious), and "Solar Facilities C&D Soils" (25% impervious). Using the same process as before, the runoff coefficients were weighted to be 0.53 and 0.32, for Drainage Area A and Drainage Area B, respectively. The drainage area imperviousness and resulting peak flow rates from pre -and post -development conditions are summarized below. See Appendix C for the runoff coefficient calculations.

Because of this, a detention basin facility will not be proposed. Instead, two grass swales will be introduced, one near the southwest site boundary of Drainage Area A and another near the south site boundary of Drainage Area B, to dissipate energy and attenuate any potential flow increase from gravel roads and concrete pads. Erosion Control/Stormwater Management Plan Erosion control features such as silt fences and grass swales (also mentioned above) will be installed on the site prior to construction activities. Such measures will be included in the erosion control plan and detail sheets within the final construction documents. Grass swale sizing calculations are summarized in Appendix D. Conclusion The drainage study and attached drainage maps were produced in accordance with requirements from Weld County Engineering and Construction Criteria Manual, updated January 2021. The existing stormwater flow characteristics are expected to remain unchanged and increases in peak flow rates have been proven to be negligible. A basin type of stormwater detention would not be necessary. Improvements proposed with the project site are limited to a gravel paved drive and a small concrete distribution transformer pad. No public access or utility infrastructure improvements are anticipated at this time. The proposed development will not alter historic drainage patterns or adjacent and downstream property owners.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. e Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 3/3/2022 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part HARRING_DA_C_SOILREPORT Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff.

College Avenue, Suite 206 Fort Collins, CO 80524 Prepared by: KELLAR ENGINEERING skellar@kellarengineering.com www.kellarengineering.com 970.219.1602 phone October 31, 2022 Sean K. Kellar, PE, PTOE This document, together with the concepts and recommendations presented herein, as an instrument of service, is intended only for the specific purpose and client for which it was prepared. Reuse of and improper reliance on this document without written authorization from Kellar Engineering LLC shall be without liability to Kellar Engineering LLC. 1.0 Introduction The purpose of this Traffic Letter is to evaluate the proposed traffic generated by the proposed Harring Solar Site project located at the southeast quadrant of Weld County Road 39 (CR 39) and Weld County Road 76 (CR 76) in Weld County, CO. 2.0 Proposed Development The proposed project consists of a solar field land use on the property. Access to the site is proposed from an existing low traffic volume access road off of CR 39 on the west side of the property. See Figure 1: Vicinity Map and Figure 2: Site Plan. Figure 1: Vicinity Map KELLAR ENGINEERING Harring Solar Site Traffic Letter -Page 2 3.0 Trip Generation Site generated traffic estimates are determined through a process known as trip generation. Rates and equations are applied to the proposed land use to estimate traffic generated by the development during a specific time interval. The acknowledged source for trip generation rates is the Trip Generation Report published by the Institute of Transportation Engineers (ITE). The Institute of Transportation Engineers' (ITE) Trip Generation Manual does not provide detailed data on solar field facilities. As such, KE was able to estimate the weekday peak hour trip generation for the AM and PM peak hours based upon information provided by the client and project team. The project team provided the following trip generation data: Trip Generation Data: • Maximum anticipated number of daily trips per day during peak period of construction = 10 — 15 vehicles per day during peak construction 7:00 AM - 3:30 PM general hours Monday — Friday. • % of heavy vehicles during peak period of construction = 5% - 10% during first few months of construction. • Typical anticipated number of daily trips after construction is complete = 2 — 4 trips per year depending on O&M contract details • Approximately 50% of the traffic will come from the west on SH 60 and approximately 50% of the traffic will come from the east on SH 60. Based upon the above data, the project is conservatively anticipated to generate a maximum of approximately 48 daily trips, 24 total (14 entering, 10 exiting) AM peak hour trips, and 20 total (6 entering, 14 exiting) PM peak hour trips.

EXHIBIT D OPERATING REQUIREMENTS The Generation Facility shall operate at a specified fixed Power Factor: The specified Power Factor as a condition of interconnection: 95%; Absorbing VARs (Leading) This Power Factor is specified at the: Point of Common Coupling The power factor may be changed from time to time by mutual agreement. A temporary power factor may be specified by Public Service Company of Colorado d/b/a Xcel Energy as a condition of operation in lieu of disconnecting when the distribution system is in a contingency configuration. The system owner is responsible to operate and maintain all equipment per manufacturer specifications and guidelines. Start -Up, Shut -Down, and Ramp Rates (Applicable for systems above 100kW with more than 1 inverter): • In order to mitigate voltage variations, where the Generation System consists of more than one unit (e.g., inverters in a solar PV context), with aggregate rating of 100kW AC or above; Interconnection Customer shall stagger the planned start-up and shutdown of the units in 50%+/- increments if only two inverters, 33% +/- increments if three inverters and 25% +/- increments if four or more inverters, with a minimum delay of 30 seconds between the starting and controlled stopping of each unit,. A controlled planned shutdown may be a condition of interconnection. The sequence of operation, including estimated timeframes for actions, must be submitted to and approved by Xcel Energy in advance. • In order to mitigate voltage variations and surges, Xcel Energy reserves the right, based upon the Engineering Study, to have Customer modify Start-up, Shut Down, and Ramp Rate requirements, within the equipment's capability. Customer shall comply with the request for modification in a timely fashion in accordance with good utility practices. • Specific to Customer's Installation: Generation shall wait a minimum of 5 minutes to start up if disconnected from service for any reason. Applicable If Energy Storage Systems Are Involved: Three Energy Storage Guidance Documents ("Guidance Documents") address battery configurations and requirements related to the terms of Colorado Public Utilities Commission Proceeding No. 16AL- 0048E. Energy storage interconnections are allowed as addressed in these Guidance Documents. The interconnection principles illustrated also apply to large interconnections, as permitted in the filed tariffs. In the event of a conflict between this Operating Agreement and Guidance Documents, the Guidance Documents shall rule. Energy storage system interconnections not included in this PUC Proceeding must be documented and be in accordance with the Engineering Study and applicable tariffs. Nothing under the Guidance Documents shall be construed to limit the export of actual onsite renewable self -generation that is net metered in compliance with the approved tariffs. Exclusions Certain tariff and generation interconnection types are outside the provisions of PUC Proceeding No. 16AL-0048E and are not covered in the Guidance Documents. Each Guidance Document lists the relevant interconnection types excluded. Energy storage system interconnections not included in this proceeding must be documented and be in accordance with the Engineering Study and applicable tariffs. Additional Definitions "Configuration" - the physical electrical design of the Distributed Energy Resource ("DER"). The Guidance Documents provide diagrams showing representative typical connection designs for a small PV as examples. The Configuration is a combination of the illustrated connection and the diagram notes concerning the equivalent connections inside of a software -governed inverter. "Distributed Energy Resource (DER)" - a source of electric power that is not directly connected to a bulk power system. DERs includes both generators and energy storage technologies capable of exporting active power to the Area Electric Power Supplier ("EPS") as defined by the Institute of Electrical and Electronics Engineers ("IEEE") standard 1547-2003. "Energy Storage Guidance Documents" or "Guidance Documents" - Guidance documents for the interconnection of electric storage based on agreed to terms from Proceeding No. 16AL-0048E and as published on the Xcel Energy website. "Inadvertent Export" - the unscheduled and uncompensated export of real power generated from a customer's parallel operation and delivered to the Company. The use of an internal transfer relay, energy management system, or other customer facility hardware or software system(s) intended to prevent the reverse power flow, or net export, from the customer's energy source across the point of interconnection shall be required. The magnitude of energy export shall be less than the aggregate nameplate rating (kW -gross) of all sources ineligible to export power (Non -Export) multiplied by one hour per month, and the duration of export of power from the customer's parallel operation shall be less than 30 seconds for any single event. "Interconnected DER Capacity" - the aggregate nameplate ratings of the DER that can be simultaneously supplied to the grid, such as storage and self -generation. If the contribution of the energy storage to the total contribution is limited by programming or by some other onsite limiting element, the reduced ongoing capacity will be used. "Material Change" - any modification to the system that causes the system to operate contrary to the approved operating configuration shall be considered a material change and shall be considered a material breach of this Agreement. "Non -Export" - a restriction whereby no Parallel Operation of Self -Generation or Energy Storage energy may export from the utility service meter to the utility is allowed and for which no payment will be given. Non -Export also applies to specific sources not allowed to export, such as batteries. Export of non-renewable sourced energy is not allowed. Non -Export restrictions are subject to the "Inadvertent Export" definition. "Operating Mode" - a combination of the functionality in the physical Configuration and the functionality in the software programming some of which is not shown in the Configuration diagram. Operating Mode is the combined function designed to achieve an Operating Objective that may vary with a change of settings. Operating Modes are established as a function, not by a diagram designation. Operating Modes include, but are not limited to, battery non -export, maximize self - consumption, maximize export, perform time shifting, and perform peak shaving. A change of Operating Mode may constitute a change of Operating Objective. "Operating Objective" - the functional purpose of the DER operation achieved by the combination of the approved Configuration and Operating Mode. Any alterations to an Operating Mode may result in unacceptable changes to the Operating Objective as originally approved. Such changes may render the facility ineligible for use without additional mitigations. "Parallel Operation of Energy Storage" - a source operated in parallel with the grid when it can supply energy to the customer simultaneously with the Company supply of energy. "Self -Generation" - a customer supplying all or part of their entire load from onsite generation with no intent of exporting that self -generated power or receiving payment for export. Energy Storage Requirements and Additional Information 1. The energy storage design follows Guidance Document and Configuration and follows all provisions of associated requirements. 2. Per the Guidance Documents, interconnection study, and interconnection tariff, the Operating Modes allowed for the energy storage shall be limited to applicable Operating Modes allowed under the Energy Storage Guidance and Tariff. 3. Any change in Configuration or Operating Mode from the Configuration or Operating Mode specified in the application that impacts the ability of the energy storage system to adhere to the applicable and approved Configuration and Guidance Document requirements may be considered a material change and may require partial or full review of the facility, which may require additional system mitigations. 4. Excluded modes are any Operating Modes not included and approved as part of the interconnection review. Configurations and Operating Modes Excluded: No Configuration or Operating Modes that include a battery storage system have been approved in this review. 5. Inverter software programming or other programming required to meet the energy storage guidance requirements shall be inaccessible and/or password protected with access restricted to manufacturer/developer/installer. This may include locks or other physical security or other means of securing the settings; or as mutually agreed upon on a case -by -case basis and identified in this Energy Storage System section of Exhibit D: N/A. 6. Any energy storage system that cannot be secured in a single Operating Mode must be reviewed for compliance with the guidelines for all Configurations or Operating Modes that are user selectable. The application must have all unapproved Operating Modes documented under Excluded Modes in paragraph 4 above and the applicable Guidance Document. Any use of excluded or unapproved Configurations or Operating Modes may be grounds for disconnection and termination of the Agreement subject to cure provision in IA Section VIII.H to which this Exhibit is attached. 7. Customer accepts that for energy storage systems interconnected per Guidance Document No. 3, Configurations will result in some loss of Production Meter recorded RECs and corresponding payments for installations eligible for REC payments. This is due to battery energy storage systems' consuming some power for maintaining a charge along with the discharge -charge cycle resulting in turn -around losses. 8. For energy storage systems interconnected per Guidance Document No. 3, Configuration 3A, with a protected load panel, a meter socket shall be installed between the hybrid inverter and protected load panel for the installation of a uni-directional Load meter by utility. 9. Telemetry requirements are determined based on the Interconnected DER Capacity with requirement thresholds outlined in the Technical Requirements. Telemetry required: Yes 10. Xcel Energy reserves the right to conduct a facility inspection to verify compliance at a later date if problems arise or indications of possible non-compliance are present. 11. Specific to Customer's Installation: N/A Applicable for Systems that Require Ground Referencing Transformer Provisions: The ground referencing transformer shall be operated and maintained such that: • The grounding referencing transformer must be in service whenever the inverters or other sources are on-line and capable of producing power while connected to the utility. • At any time the grounding transformer is unavailable, the inverters or other sources must not be allowed to start or restart a connection to the utility. • Specific to Customer's Installation: N/A Applicable to Systems Over 100 kW AC when Disconnection Due to System Constraints or Safety may be Required: Disconnection or Curtailment Requirements of the generating system when required pursuant to Section VIII.F) of the Generating System Interconnection Agreement (IA) to which this Exhibit is attached: Public Service may disconnect the Generation System as reasonably necessary in the event of imminent danger to the public or Public Service personnel, and routine maintenance, repairs, and modifications to the Public Service system. See IA VIII.F) for notification by Public Service provisions. The Interconnection Customer shall ensure that at all times Public Service has access to a manually operated three-phase lockable disconnect switch pursuant to Section VIII.B) of the IA. Interconnection Customer agrees and consents to Public Service's remote tripping or manual disconnection, as reasonably necessary under good utility practice, of the utility owned disconnecting device or other agreed to facility device for the Generation System including, but not limited to, in the following circumstances, when system conditions exceed parameters defined in any IEEE, NESC, ANSI standards, prudent safety practices, system capacity limits, or utility system contractual limits: • Electric Distribution or Transmission System emergency • Public emergency • Abnormal system operation • Planned switching • Transmission system constraints The above may have situations where a partial reduction in Facility output may adequately alleviate the problem. If partial curtailment is an option for one or more of the above conditions, the applicant will need to demonstrate how this can be accomplished. Interconnection Customer's failure to promptly respond to and execute on Public Service's request to curtail the output of the Generation System, it will be disconnected either manually or remotely by Public Service Company. If Public Service remotely trips the disconnecting device for the Generation System, Public Service will close the device remotely, if so equipped, after attempting to notify the Large Interconnection Customer's Control Center Contact. Public Service will close their device remotely once the reason for the remote tripping has passed and it is safe and consistent with good utility practice to do so. If the disconnection was done manually, Public Service will close the device in a timely manner. The Generation System is subject to curtailment or disconnection for the following defined limitation in addition to the above conditions: (N/A if none) Describe: N/A Remotely operated separation device, if other than utility owned, agreed to by the Large Interconnection Customer: (N/A if none) Describe: N/A Control Center Contacts: Each Party shall contact each other's Control Center Contact for all operational issues related to the Generation System, pursuant to IA Section XII.B). In order to permit Public Service and the Large Interconnection Customer to take immediate action, the Large Interconnection Customer and Public Service shall at all times provide to each other the contact information of each other's Control Center Contact, which shall be available twenty-four (24) hours a day, seven (7) days a week and be able to take action with respect to the operation of the Generation System and the Distribution System, respectively. Each Party shall keep the other informed of their Control Center contact information. Notice of changes to Control Center contact information shall be provided when such changes occur.

Dear Ms. Cornell, Thank you for the opportunity for Colorado Parks and Wildlife (CPW) to comment on the proposed Cloudbreak Energy Partners (CBEP) Harring Solar Project (Solar Project), located just northeast of the Town of Eaton (T7N, R65W, S32). We recognize renewable energy development is important to meeting the State's greenhouse gas reduction goats and improves our climate resiliency. It is our understanding that this 32.5 -acre Solar Project would produce roughly 4.625 megawatts in alternating current (MWac) of renewable energy. CPW also understands that a 400 -foot -long 12.47kV overhead transmission line for this Solar Project wilt be required for an interconnect to an adjacent Xcel transmission line. CPW further understands that this consultation is a component of the eventual Weld County permitting process. CPW appreciates that CBEP and TRC have initiated early consultation with CPW because it can lead to a responsibly -developed project that works toward achieving state solar goals' while protecting sensitive wildlife species, habitats, and time frames. The mission of CPW is to perpetuate the wildlife resources of the state, to provide a quality state parks system, and to provide enjoyable and sustainable outdoor recreation opportunities that educate and inspire current and future generations to serve as active stewards of Colorado's natural resources. CPW has a statutory responsibility to manage all wildlife species in Colorado; as such we encourage protection for Colorado's wildlife species and habitats through responsible energy development and land use planning. One way we achieve this goat is by responding to referral comment requests, as is the case for this project. CPW encourages developers to afford the highest level of protection to Colorado's High Priority Habitats I https://energyoffice.colorado.gov/climate-energy/ghg-pollution-reduction-roadmap Heather Dugan, Acting Director, Colorado Parks and Wildlife • Dan Prenzlow, Director, Colorado Parks and Wildlife Parks and Wildlife Commission: Carrie Besnette Hauser, Chair • Dallas May, Vice -Chair • Marie Haskett, Secretary • Taishya Adams Karen Bailey • Betsy Blecha • Gabriel Otero • Duke Phillips, IV • Richard Reading • James Jay Tutchton • Eden Vardy Harring CBEP Solar Project — CPW Comments (7/12/22) Page 2 of 3 (HPHs). HPHs are defined as sensitive wildlife habitats where CPW has sound spatial data' and scientifically -backed best management practice recommendations to help developers with the siting process to minimize any impacts. RECOMMENDATIONS FOR THIS PROJECT CPW appreciates this formal consultation from TRC and CBEP. Early consultation is our preferred time to discuss any concerns or questions about the proposed Solar Project. CPW also appreciates that this Solar Project is located outside of HPHs. CPW encourages the following recommendations for this project: • CPW is aware that the Project area will include security fencing. For specific wildlife exclusion fencing specifications, CPW recommends that any installed fencing should be eight feet in height, have round -capped posts (e.g., so wildlife isn't impaled), smooth top wire to the fence (e.g., no top barbed wire) (or if two top strands are needed, ensure they are at least six inches apart). The bottom wire can be barbed but should be four inches or less from the ground. • CPW recommends that other non -security fencing is kept to a minimum. Where such fencing is required, please use wildlife -friendly fencing specifications as described in CPW's document entitled "Fencing with Wildlife in Mind3". • CPW recommends that the solar facility is checked weekly (or escape structures are installed inside the fenced area) to allow deer to escape if one becomes trapped within the facility. • CPW requests that security lighting is kept to a minimum and ideally motion sensor lights are installed. It is important to avoid lighting the riparian corridors along the sides of the project. • If construction is slated from March 15 to July 15, please complete pre -construction nesting surveys for songbirds, Burrowing Owls, and ground- or tree -nesting raptors' within the Project area or in the immediate vicinity (e.g., their buffers may extend into the Project area) within a couple of weeks of construction. • For the eventual consultation regarding transmission lines to this Solar Project, CPW recommends they are installed according to Avian Power Line Interaction Committee (APLIC) standards5 and outside the raptor nesting season. Also, please install bird diverters within 1/4 -mile of any lake, drainage, or riparian area, and within the raptor nesting buffer for occupied nests. CPW appreciates the opportunity to review this project and provide comments and recommendations to avoid and minimize impacts to wildlife resources.
