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 the agricultural heritage of the County by ensuring that the property can remain irrigated and agriculturally productive through sheep grazing on the property. ii. Respects private property rights by allowing the owner of the property t0 do what is in their best interest while complying with local regulations and not interfering with or infringing upon the rights of others. iii. 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. iv. Protects the health, safety, and general welfare of the citizens of the County by providing an emission -free source of energy. v. Is harmonious with surrounding agricultural and industrial uses. vi. 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 As stated in Chapter 23 of the Code, the 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 and energy development, without the interference of other, incompatible land uses. The Project is consistent with the intent of this zone district because although it is an energy development, agricultural production will continue on the property. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. (970) 425-3175 I I N FO©a CLOU DBPEAKEN EPGY.COM I CLOU DBPEAKEN EPGY.COM CLOUDBREAK PAGE6 o The Project will be located between the Town of Milliken and the Town of Johnstown along Highway 60. o The Project's area is included in the 2021 Johnstown Comprehensive Plan as a future Medium Density/Intensity area. As described in the Johnstown Comprehensive Plan, the Medium Density/Intensity area will "generally be characterized by a more balanced, and wider -ranging mix of land uses incorporating walk-up apartment buildings, townhomes, small lot (3,500-5,000 SF) attached and detached single-family housing, in close proximity to neighborhood scale shopping, personal services, restaurants, small medical facilities, and facilities such as libraries and recreational centers. MDI areas may also occur along arterials and other major corridors, and may serve as the next layer away from the High Density/Intensity areas they may neighbor, as a transition to lower density neighborhoods. MDI's will offer complete neighborhoods with a diversity of shops and services, including schools and civic facilities, within walking or biking distance from residential areas; and offer good walking connections along with larger -scale multi -modal trails." The Project is a great way for the Town of Johnstown to transition from Higher Density/Intensity areas to lower density neighborhoods and from the downtown Johnstown area to the west to Milliken's business/industrial area to the east. o After discussing the Project with the Town of Johnstown, CBEP Solar 5, LLC made the following changes to its USR Plan to ensure that the Project does not interfere with the Town's future plans: i. Added a 55' setback along the western boundary of the parcel in order to allow for the expansion of County Road 19. ii. Added a setback along the eastern boundary of the parcel in order to allow for the expansion of Johnstown's sewage infrastructure. o The Project's area is not included in the adopted master plan of the Town of Milliken, but is located adjacent to an area expected to be a business/industrial area according to the Town's adopted master plan. The project will be compatible with the expected business/industrial use of nearby property within the Town of Milliken because it will not generate any traffic or negatively impact the nearby business and industrial uses. 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, and 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. (970) 425-3175 I INFO©aCLOUDBFREAKENEPGY.COM I CLOUDBPEAKENEPGY.COM CLOUDBREAK PAGE 7 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 CBEP Solar 5, LLC and the landowner are working together to install a drip irrigation system alongside the Project so that the land can continue to be irrigated throughout the duration of the Project's life. The land will retain its agricultural use through sheep grazing. 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 The Project is not located within any Overlay Zoning Districts or Special Flood Hazard Areas. 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 will be required, and one additional State permit that might be required. The two required State permits are the Colorado Department of Public Health and Environment Construction Stormwater Discharge Permit and the Colorado Department of Public Health and Environment Air Permit. The one additional State permit that might be required is a Colorado Department of Transportation Access Permit for access to the Project from State Highway 60. No applications for State permits have been submitted.

Indicate if there will be any air emissions (e.g. painting, oil storage, etc.): o Traffic volume, primarily in the form of passenger vehicles, would increase in and around the Project area during construction. The increased traffic would temporarily increase odors and exhaust from vehicle emissions. Odors are anticipated from the operation of heavy machinery during grading, pile driving, and other installation activities at specific time periods throughout construction. Impacts from odors during Project operation would be minimal, likely restricted to emissions from the vehicles of maintenance personnel. 9. Provide a design and operations plan if applicable (e.g. composting, landfills, etc.): o A design and operations plan is not applicable to the Project. 10. Provide a nuisance management plan if applicable (e.g. dairies, feedlots, etc.): o A nuisance management plan is not applicable to the Project. 11.

The Project includes construction of 5 Megawatts (MW) of solar electric generation on a 37.46 -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 will be surrounded by a 7 foot tall game fence. Please refer to sheet C-401 of the USR Map for additional detail on the proposed security fence. The fence on the southern and eastern boundaries of the Project will include a woven mesh fabric, or similar screening, to provide additional screening of the site and to mitigate potential glare. An example photo of woven mesh fabric is provided below as Figure 1. In partnership with the Audubon Society, the fence on the eastern, southern, and western boundaries of the Project will include pollinator habitats on the exterior of the fence that will provide additional screening. Additional detail on the proposed Audubon Society pollinator habitat can be found on sheet C-302 and sheet C-400 of the USR Map. This pollinator habitat will be irrigated by a drip irrigation system that the landowner is installing on the property for the irrigation of sheep forage, and consists of native plants that will require very little maintenance. The installation of the pollinator habitat is expected to take place in spring of 2023.

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 5, 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 native seed to revegetate disturbed areas and hold soil in place, minimizing fugitive dust impacts during operations. CBEP Solar 5, LLC would employ native revegetation methods or chemical control methods for infestations of weeds during regular maintenance if necessary.

During construction, CBEP Solar 5, 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 irrigated sheep forage, which will mitigate dust. Weed Control: • Once construction is complete, the Project will be seeded with sheep forage and will utilize sheep grazing to maintain the land. The site will be inspected annually by CBEP Solar 5, 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.

Tue, Mar 29, 2022 at 3:44 PM I had the chance to meet with the landowner, and he is potentially interested in annexing the property into Johnstown, but he needs some time to think through the decision and consider all of his options (Milliken was also interested in annexing). So the plan he and I came up with is that we are going to continue permitting the solar projects with Weld County while he and his family figure out the pros/cons of annexation (at some point, he will likely be reaching out to you to set up another meeting to discuss) and then make the final annexation decision after our USR process with Weld is complete. So, for the time being, we are going to continue pursuing a USR permit from Weld. I will be sure all of the items we discussed are included in the site plans. Also, I might have lost it somewhere, but have you had the chance to fill out the NOI form for Weld County? I've attached it below for your review.

This proposed solar project is located within the Town of Johnstown Growth Management Area, on land anticipated for future development. The 2021 Johnstown Area Comprehensive Plan indicates anticipated medium intensity and density development, with a mix of uses, along this high -traffic Highway 60 "gateway" corridor. Our economic development manager has indicated the desire to work with future developers along this corridor to create an area for light industrial and employment uses along the Hwy 60 corridor, to complement the uses at the Colorado Sweet Gold site as well as the east -end industrial uses in Johnstown. We would be interested in pursuing annexation of this property. The Town has also been investigating the ability to extend Weld County Road (CR) 19 north to CR 48.5 to increase the transportation connectivity of this area with the overall community, especially in light of the location and proximity of the existing railroad tracks to Hwy 60. We are in the beginning stages of a full replacement for our Central Waste Water Treatment Plant, as well as a connection of a large sanitary sewer interceptor that will extend north to CR 48.5, and along CR 50 to the west to serve our growing community. Obtaining the necessary easement has been discussed with the current property owners, and the Town would like to see that accommodated in any revised site plans. Screening and overall development scenario seems acceptable, otherwise. The Community That Cares johnstown.colorado.gov P: 970.587.4664 1450 S.

NOT FOR PERMITTING, BIDDING, NOR CONSTRUCTION. Prepared by or under the Direct Supervision of: Kelsey Blaisdell, P.E. 49698 "5/16/2022" Cloudbreak Energy is pursuing development of the Griffiths 1 Project, a photovoltaic energy generation facility at a 37.5 -acre site located approximately 1.5 miles northwest of Milliken, Colorado, alongside SH-60 with access from Co Rd 48.5 (See Appendix A -Site Plans C301 & C302). The existing site currently is used for agricultural purposes with approximately 1% slopes. This drainage study was prepared to summarize findings from performing a hydrologic analysis of the project site to identify the potential storm water impact from the proposed solar project and develop appropriate drainage best management practices (BMPs) to address the impact. This drainage study was prepared to comply with the requirements from Weld County Engineering and Construction Criteria (WCECC) Manual, updated January 2021. Proposed Project The proposed solar project will consist of pole mounted photovoltaic (PV) arrays. Ground disturbance under the panels will be minimal; thus, existing perviousness of the soil will be maintained under the solar cells allowing infiltration. Rainfall runoff from the panels will 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 transforms (see Appendix A - Site Plans C301 & C302). 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 mainly consist of hydrologic soil group (HSG) A and B soils given by the Natural Resources Conservation Service (NRCS — Appendix B). A single drainage basin Labeled as Drainage Area A has been identified for the project site and is approximately 37.5 acres. Any offsite flows appear to follow the existing ditches and are not expected to affect the project site. See Appendix A for the drainage area maps and details. A hydrologic analysis was prepared using the Rational Method based upon requirements from WCECC Manual. The analysis provided estimated peak flow rates for the 100 -year storm under both pre- and post -development conditions. The design rainfall depth for a 1 -hour, 100 -year storm is 2.77 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 1 Stormwater Drainage Study A. Runoff coefficients for various land uses were obtained from Table 5-2, Weld County Engineering and Construction Criteria. 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=C*I*A Where: Q- Runoff flow rate in cubic feet per second (cfs) /— Rainfall Intensity in inches per hour (in/hr) A - Area of the basin in acres (ac) Pre -development Runoff Calculation Parameters Drainage Area Area, A (ac) Weighted Coefficient, Runoff C Intensity, Rainfall (in/hr) A 37.50 0.3182 5.17 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 37.50 0.3217 5.17 2% 100 -year Runoff Calculation Results Drainage Area Pre -development Peak Flow (cfs) Rate Post Peak -development Flow (cfs) Rate DIFFERENCE (cfs) A 61.64 62.39 0.75 Based upon the above results, the increase of impervious area would produce little increase (approximately 1.2%) in the peak flow rate. Because of this, a detention basin facility will not be proposed. Instead, a grass swale will be introduced near the south project site boundary 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 a grass swale (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. 2 Stormwater Drainage Study 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 storm water flow characteristics are expected to remain unchanged and increases in peak flow rates have been proven to be negligible. A basin type of storm water detention would not be necessary. Improvements proposed with the project site are limited to a gravel paved drive and two small concrete distribution transformer pads. No public access or utility infrastructure improvements are anticipated at this time. Proposed development will not alter historic drainage patterns and adjacent and downstream property owners. 3 Stormwater Drainage Study References 1.

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

NOT FOR PERMITTING, BIDDING, NOR CONSTRUCTION. Prepared by or under the Direct Supervision of: Kelsey Blaisdell, P.E. 49698 "5/16/2022" Cloudbreak Energy is pursuing development of the Griffiths 1 Project, a photovoltaic energy generation facility at a 37.5 -acre site located approximately 1.5 miles northwest of Milliken, Colorado, alongside SH-60 with access from Co Rd 48.5 (See Appendix A -Site Plans C301 & C302). The existing site currently is used for agricultural purposes with approximately 1% slopes. This drainage study was prepared to summarize findings from performing a hydrologic analysis of the project site to identify the potential storm water impact from the proposed solar project and develop appropriate drainage best management practices (BMPs) to address the impact. This drainage study was prepared to comply with the requirements from Weld County Engineering and Construction Criteria (WCECC) Manual, updated January 2021. Proposed Project The proposed solar project will consist of pole mounted photovoltaic (PV) arrays. Ground disturbance under the panels will be minimal; thus, existing perviousness of the soil will be maintained under the solar cells allowing infiltration. Rainfall runoff from the panels will 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 transforms (see Appendix A - Site Plans C301 & C302). 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 mainly consist of hydrologic soil group (HSG) A and B soils given by the Natural Resources Conservation Service (NRCS — Appendix B). A single drainage basin Labeled as Drainage Area A has been identified for the project site and is approximately 37.5 acres. Any offsite flows appear to follow the existing ditches and are not expected to affect the project site. See Appendix A for the drainage area maps and details. A hydrologic analysis was prepared using the Rational Method based upon requirements from WCECC Manual. The analysis provided estimated peak flow rates for the 100 -year storm under both pre- and post -development conditions. The design rainfall depth for a 1 -hour, 100 -year storm is 2.77 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 1 Stormwater Drainage Study A. Runoff coefficients for various land uses were obtained from Table 5-2, Weld County Engineering and Construction Criteria. 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, a grass swale will be introduced near the south project site boundary 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 a grass swale (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. 2 Stormwater Drainage Study 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 storm water flow characteristics are expected to remain unchanged and increases in peak flow rates have been proven to be negligible. A basin type of storm water detention would not be necessary. Improvements proposed with the project site are limited to a gravel paved drive and two small concrete distribution transformer pads. No public access or utility infrastructure improvements are anticipated at this time. Proposed development will not alter historic drainage patterns and adjacent and downstream property owners. 3 Stormwater Drainage Study References 1.

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

The Project is located near Johnstown, Weld County, Colorado. Figure 1 demonstrates the proposed PV array locations 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\-1WPMSN\PJT2\434718\0000\000014\M4347180000PH14-001.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 CBEP. 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 arrays, observation points (OPs), and route receptors evaluated. The same receptor parameters were used for each grouping of arrays analyzed. 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 until the sun sets below the horizon. 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 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. \\madison-vfp\Records\-1WPMSN\PJT2\434718\0000\000014\M4347180000PH14-001.docx Technical Memorandum Page 3 of 5 Observation Point Parameters Solar glare hazard analyses were conducted for selected residences and Town of Johnstown operational building 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. No two-story residences were identified in the Weld County Property Portal. 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 Assumed One Story Residence on 9216 W County Road 48.5 6 OP2 Assumed Mobile Home at 9216 W County Road 48.5 6 OP3 Assumed One Story Residence at 9510 W County Road 48.5 6 OP4 Assumed One Story Operational Building for the Town of Johnstown 6 Route Receptors TRC also analyzed the adjacent roadways, Hwy 60 and W County Road 48.5, 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 W County Road 48.5. 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. \\madison-vfp\Records\-1WPMSN\PJT2\434718\0000\000014\M4347180000PH14-001.docx Technical Memorandum Page 4 of 5 Results, Recommendations, and Conclusions TRC conducted the solar glare hazard analysis using the FAA -approved SCHAT 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.

Yellow glare may be visible for less than 15 minutes per day from approximately 5:30 pm to 7:30 pm during early -March through September. • Highway 60 is located along the southern boundary of the array area. Yellow glare may be visible for up to 40 minutes per day from approximately 4:30 am to 6:15 am and 6:00 pm to 7:30 pm from late -March through mid -September for commercial vehicles traveling along the evaluated section of Highway. For passenger vehicles, yellow glare may be visible for up to 15 minutes per day from approximately 5:00 am to 6:00 am and approximately 6:00 pm to 7:30 pm from late -March through mid -September. Based on the glare hazard analysis performed for the Project with the project specifications provided above, no green or red glare is expected to be visible at the OPs and along the Route Receptors evaluated. However, yellow glare is modelled to be observed at OP2 and OP4 and along Highway 60. It should be noted that ForgeSolar uses a simplified model for backtracking, where it assumes that the panels instantaneously revert to the resting angle when the sun is outside the panel rotation range. This assumption provides a worst -case scenario for glare estimates, so actual glare amounts may vary from the model. CBEP is evaluating several methods to mitigate the glare estimated to be visible at the above receptors. These methods include using vegetive or privacy screening around the perimeter of \\madison-vfp\Records\-1WPMSN\PJT2\434718\0000\000014\M4347180000PH14-001.docx Technical Memorandum Page 5 of 5 the array. If used, vegetative screening should include evergreen trees/coniferous trees, which could be maintained in order to block the array area from an observer throughout the year. In addition to physically screening options, 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 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\-1WPMSN\PJT2\434718\0000\000014\M4347180000PH14-001.docx Attachment 1 Griffiths Solar - Parcel 1 Project Solar Glare Hazard Analysis Reports 11madison-vfp\Records\-1WPMSN\PJT21434718100001000014\M4347180000PH14-001.docx ;` Forge Rv planning & glare analysis • FORGESOLAR GLARE ANALYSIS Project: Griffiths Solar Project A proposed solar installation near Johnstown, 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.)

College Ave, Suite 206 Fort Collins, CO 80524 Email : jschlangen@trccompanies.com Subject: Site Acoustical Evaluation Griffiths Solar Facility Milliken, CO Acentech Project No. 635261 Dear Jamie: 33 Moulton Street 4s4 Cambridge MA 02138 617 499 8000 acentech.com In connection with Cloudbreak Energy Partners' development of the Griffiths Solar Facility (the Project), we have conducted an acoustical evaluation for the Project. The primary objective of our evaluation was to predict sound transmission from sound -producing equipment to nearby community receivers. The sound - producing equipment evaluated in this study includes transformers and inverters. GLOSSARY OF TERMS To facilitate understanding of the technical terms used throughout the report, we have provided the following glossary: A -weighting — a sound data filter that adjusts the sound level for frequency content to better represent the human perception of sound. dB — decibel, unweighted sound level. Note that this can be used to refer to relative increases in sound pressure level as well as overall sound level. dBA or dB(A) — A -weighted sound level. Note that this only refers to overall sound level, never relative increases in sound level. LA10 the A -weighted sound level (dBA) exceeded 10% of the measurement interval. Typical of brief transient sound events. LA90 — the A -weighted sound level (dBA) exceeded 90% of the measurement interval. Typical of continuous sounds, and often similar to the minimum sound level. Also known as the "background noise level." LAeq — the A -weighted average continuous equivalent sound level (dBA). Often referred to as Leg. Lp — Sound Pressure Level, dB relative to 20 micro -Pascals. For the purposes of this evaluation, it is used to represent sound at any given receiver point in the community. LW - Sound Power Level, dB relative to 1 pico-watt. For the purposes of this evaluation, it is used as the input sound level at the "source" (the noise -producing equipment). acoustics 0 technology I vibration Jamelle Schlangen March 10, 2022 Page 2 of 13 PROJECT NOISE GUIDELINES Weld County "Use By Special Review (USR)" Procedural Guide We have reviewed the Weld County "Use By Special Review (USR)" Procedural Guide, which describes required steps for Project approval. According to the Guide checklist, the Project must conduct a: "noise study including a noise abatement plan documenting the methods to be utilized to meet the applicable noise standard, as determined by Environmental Health." The procedures outlined in this report are intended to serve as that noise study. The applicable noise standard is described below. Colorado Noise Statute According to the Colorado Noise Statute (25-12-103): "Sound levels of noise radiating from a property line at a distance of twenty-five feet or more therefrom in excess of the dB(A) established for the following time periods and zones shall constitute prima facie evidence that such noise is a public nuisance." The time periods and zones, along with their associated noise limits, are listed below in TABLE 1. We understand that all of the abutters are either residential or commercial properties. TABLE 1: Colorado Noise Statute — Noise Limits at Property Lines Zone Noise Limit 7:00 AM to 7:00 PM 7:00 PM to 7:00 AM Residential 55 dB(A) 50 dB(A) Commercial 60 dB(A) 55 dB(A) Light Industrial 70 dB(A) 65 dB(A) Industrial 80 dB(A) 75 dB(A) METHODOLOGY In order to provide context for our study, we first measured ambient sound levels at the site. Taking note of the quietest daytime and nighttime sound levels allowed us to establish a benchmark for comparing Project noise with existing sound sources. We then used sound data for the noise -producing equipment to build a computer model that can predict noise propagation to the community. The evaluation herein evaluates sound levels due to noise -producing equipment at all property lines adjacent to the Project. BACKGROUND NOISE SURVEY Acentech performed unattended sound measurements from January 6 to January 13, 2022 using two sound level meters (SLM). The particular instruments we used were model NL-52 by Rion. The equipment is calibrated annually as well as field calibrated immediately prior to use and upon retrieval to ensure accuracy. The locations of our SLMs are shown in FIGURE 1. We obtained data in 1 -hr intervals, including LAeq and other statistical metrics (e.g., LA1o, LA90). FIGURES 2 & 3 present time histories of environmental sound levels measured at each monitoring location. The LA90. shown in blue, is the key sound metric for evaluating sound emissions from steady-state sources like transformers and inverters. For reference, we have also included the LAeq and LA01 (defined above in the Glossary) to represent some of the louder, less frequent sound events near the measurement locations. At Location 1, the quietest daytime (7:00 AM — 7:00 PM) hour had an LA90 of 29 dBA, while the quietest nighttime (7:00 PM — 7:00 AM) hour had an LA90 of 28 dBA. At Location 2, which was much closer the main thoroughfare CO -60, the quietest daytime hour had an LA90 of 37 dBA, while the quietest nighttime hour had an LA90 of 33 dBA. acoustics , technology I vibration Jamelle Schlangen March 10, 2022 Page 3 of 13 TABLE 2: Existing Ambient Sound Survey — Quietest Hour Measurement Results Location Measured Sound Level of Quietest Hour (dBA) 7 AM to 7 PM 7 PM to 7 AM Location 1 29 28 Location 2 37 33 OPERATIONAL NOISE EVALUATION Acentech developed an acoustical model of the Project and the surrounding area. The model was developed using Cadna/A software to estimate the contributions of various noise sources to the community sound levels. Cadna/A complies with the standard ISO 9613-2, which defines an internationally recognized methodology in the acoustics industry for calculating sound propagation outdoors. The current site plans used in this modeling are enclosed in APPENDIX A. To aid us in developing our model, TRC provided information about the equipment to be installed. The transformer models have not yet been selected, but we understand that they will be specified to NEMA TR-1 standards. Since we did not receive transformer sound data, we estimated transformer sound levels based on transformers from similar past projects. We understand that there will be two (2) transformers at each parcel, for a total of four (4) transformers. For the inverters, we received a specification sheet for the basis of design model: CPS SCH100. This sheet provided a single -number overall sound level (dBA) for each unit. We used this value and approximated the full spectrum by using octave band sound data from inverters on similar past projects. We understand that there will be forty (40) inverters at each parcel, for a total of eighty (80) inverters. The sound power level (Lw) inputs we used in our model are presented in TABLE 3. We have also included the relevant page from the inverter (CPS SCH100) specification sheet in APPENDIX B. N ighttime Operation During nighttime operation, we understand that the inverters will be inactive, but the transformers will be energized and producing sound. We expect that the inverter shutoff times will vary depending on daylight hours at different times throughout the year. In our modeling, we have assumed an average inverter shutoff time (i.e. the cutoff between "daytime" and "nighttime") of 7:00 PM. PRELIMINARY RESULTS We calculated noise levels at each of the eleven adjacent properties indicated on the site plan, as shown in FIGURE 4. The particular receiver locations were selected to be as close as possible to the noise -producing equipment in order to represent a "worst case scenario" sound level at each property. Calculated noise levels further from the project are shown in the sound contours, described below. We calculated the sound level at these locations with receiver heights of 1.5 meters. We then compared modeled noise levels to the noise guidance summarized above. S ound Levels at Nearby Receivers TABLE 4, enclosed, presents the estimated baseline daytime and nighttime sound levels for the Project. The ambient is defined as the LA90, as described above. Even with no mitigation measures in place, the Project is compliant with the property line noise limits outlined in the Colorado Noise Statute for both residential and commercial abutters. S ound Contours FIGURE 5 shows Project -only daytime sound contours for the broader Project area, calculated at a height of 1.5 meters, from 35 dBA to 60 dBA in 5 -dB increments. FIGURE 6 shows Project -only nighttime sound contours. The contours demonstrate that some areas of adjacent properties may occasionally register a perceptible increase over existing ambient sound levels, depending on time of day. However, this is only likely to occur during the quietest hours of the day, and only at adjacent property areas that are closest to the noise -producing equipment. We do not anticipate significant increases in existing ambient sound levels at any nearby residential buildings. acoustics , technology I vibration Jamelle Schlangen March 10, 2022 Page 4 of 13 SUMMARY The Project is expected to achieve compliance with the Colorado Noise Statute without the need for any mitigation. Any perceptible increases of existing ambient levels at nearby properties are expected to be minimal. When you specify the Projects transformers, we recommend that you select a model with sound levels no higher than those of the sample transformer we included in our model, as shown in TABLE 3. * * * * We hope this report provides all the information you need at this time.

This TIS is for the proposed Griffiths Solar Sites #1 and #3 project. The access to the project site is located from CR 48.5 east of WCR 17. See Figure 1: Vicinity Map. Kellar Engineering LLC (KE) has prepared the TIS to document the results of the project's anticipated traffic conditions in accordance with Weld County's requirements and to identify projected impacts to the local and regional traffic system. 2.0 Existing Conditions and Roadway Network The project is located east of WCR 19 and south of CR 48.5 in Weld County, Co. The project's access is proposed from CR 48.5 approximately 6,500' east of WCR 17. See Figure 2: Site Plan. CR 48.5 is an existing east/west local roadway with a posted speed of 30 mph posted east of the CR 48.5/WCR 17 intersection. 2.1 Recent Traffic Volumes Existing peak hour traffic volume counts were collected at the study intersections by All Traffic Data Services on Thursday, December 9, 2021 using data collection cameras. The traffic counts were conducted during the peak hours of adjacent street traffic in 15 - minute intervals from 7:00 AM to 9:00 AM and 4:00 PM to 6:00 PM. These turning movement counts are shown in Figure 3 with the count sheets provided in Appendix A. Griffiths Solar Sites TIS -Page 3 it: Figure 1: Vicinity Map Griffiths Solar Sites TIS -Page 4 3.0 Pedestrian and Bicycle Facilities Currently there are no existing sidewalk facilities adjacent to the streets adjacent to the project site. Additionally, the proposed land use associated with the project is not anticipated to generate additional pedestrian or bicycle trips. Any additional pedestrian or bicycle traffic from this development, if any, would be negligible. 4.0 Proposed Development The proposed project consists of a solar field land use on the property. The project's access is proposed from CR 48.5 approximately 6,500' east of WCR 17. See Figure 1: Vicinity Map and Figure 2: Site Plan. 4.1 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, 10th Edition 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 Based upon the above data, the project is conservatively anticipated to generate a maximum of Griffiths Solar Sites TIS -Page 6 li 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. See Table 1: Trip Generation.

Therefore, trip generation is based upon information obtained from the client and project team.

The directional distribution of traffic is a means to quantify the percentage of site generated traffic that approaches the site from a given direction and departs the site back to the original source. Figures 6 illustrates the trip distribution used for the projects analysis. 4.3 Traffic Assignment Traffic assignment was obtained by applying the trip distribution to the estimated trip generation of the development. Figures 7 shows the site generated traffic assignment for the project. 4.4 Short Range Total Peak Hour Traffic Site generated peak hour traffic volumes were added to the background traffic volumes to represent the estimated traffic conditions for the short range 2025 horizon. These background (2025) and short range (2025) total traffic volumes are shown in Figures 4 and 8. The short range analysis year 2025 includes the proposed development for this project plus a 1.5% increase in background traffic per the North Front Range MPO growth rates. 4.5 Long Range Total Peak Hour Traffic Site generated peak hour traffic volumes were added to the background traffic volumes to represent the estimated traffic conditions for the long range 2040 horizon. These background (2040) and long range (2040) total traffic volumes are shown in Figures 5 and 9. The long range analysis year 2040 includes the proposed development for the project plus project plus a 1.5% increase in background traffic per the North Front Range MPO growth rates. Griffiths Solar Sites TIS -Page 16 it: 5.0 Traffic Operation Analysis KE's analysis of traffic operations in the site vicinity was conducted to determine the capacity at the identified intersections. The acknowledged source for determining overall capacity is the latest edition of the Highway Capacity Manual (HCM). 5.1 Analysis Methodology Capacity analysis results are listed in terms of level of service (LOS). LOS is a qualitative term describing operating conditions a driver will experience while traveling on a particular street or highway during a specific time interval. LOS ranges from an A (very little delay) to an F (long delays). A description of the level of service (LOS) for signalized and unsignalized intersections from the Highway Capacity Manual (HCM) are provided in Appendix B. 5.2 Intersection Operational Analysis Operational analysis was performed for the short range 2025 horizon. The calculations for this analysis are provided in Appendix E. Using the short range total traffic volumes, the project's study intersections are projected to operate acceptably. See Table 5 for the 2025 Short Range Total Peak Hour Operation. 5.3 Auxiliary Lane Analysis The auxiliary lane analysis for the study intersections were conducted using CDOT State Highway Access Code (SHAG). Based upon the SHAC, a left -turn deceleration lane is required at an intersection with a projected peak hour ingress turning volume greater than 10 vph. Additionally, a right -turn deceleration lane is required at an intersection with a projected peak hour ingress turning volume greater than 25 vph. Based upon the projected traffic of the development and the State Highway Access Code (SHAG), additional auxiliary lanes are not required to accommodate the project's traffic.

The findings of the Traffic Impact Study (TIS) are summarized below: • The proposed project is conservatively anticipated to generate a maximum of approximately 48 daily total weekday trips, 24 AM total peak hour trips, and 20 PM total peak hour trips. See Table 1: Trip Generation • The study intersections are projected to operate acceptably and comply with Weld County's intersection level of service (LOS) requirements with full development of the proposed project and background traffic. See Table 5 and Table 6. • Based upon the projected traffic from the development and the State Highway Access Code (SHAG), additional auxiliary turn lanes are not required to accommodate the project's traffic. See Section 5.3. • The project's trip generation and site generated traffic is low. See Table 1: Trip Generation and Figure 7: Site Generated Peak Hour Traffic. • Due to the project's low site generated traffic, the proposed project will not create a negative traffic impact upon the local and regional traffic system and the existing roadway improvements are sufficient to accommodate the project's traffic.

G) Disconnection of Unit: Public Service may disconnect the Generation System as reasonably necessary in the event of termination of this Agreement, non-compliance by the Customer with the terms of this Agreement, system emergency, imminent danger to the public or Public Service personnel, and routine maintenance, repairs, and modifications to the Public Service system. When reasonably possible, Public Service shall provide prior notice to the Customer explaining the reason for the disconnection. If prior notice is not reasonably possible, Public Service shall, after the fact, provide information to the Customer as to why the disconnection was required. Public Service shall have no liability for any loss of sales or other damages, including any consequential damages for the loss of business opportunity, profits, or other losses, regardless of whether such damages were foreseeable, for the disconnection of the Generation System in accordance with this Agreement. Public Service shall expend reasonable effort to reconnect the Generation System in a timely manner and to work towards mitigating damages and losses to the Customer where reasonably possible. Page 3 of 11 21-02-503 SRC Generator Interconnection Agreement Colorado H) Modifications to the Generation System: The Customer shall notify the Public Service Operator, in writing, of plans for any modifications to the Generation System interconnection equipment, including all information needed by Public Service, as part of the review described in this paragraph, at least twenty (20) business days prior to undertaking such modification(s). Modifications to any of the interconnection equipment, including all interconnection required protective systems, the generation control systems, the transfer switches/ breakers, interconnection protection VT's & CT's, and Generation System capacity, shall be included in the notification to Public Service. The Customer agrees not to commence installation of any modifications to the Generating System until Public Service has approved the modification, in writing, which approval shall not be unreasonably withheld. Public Service shall have a minimum of five (5) business days to review and respond to the planned modification. Public Service shall not take longer then a maximum of ten (10) business days to review and respond to the modification after the receipt of the information required to review the modifications. A major upgrade or expansion of the Generation System does not qualify for this provision. Such changes shall be reviewed through a formal interconnection application. I) Any modification to the generation system that causes the system to operate contrary to the provisions of Public Service's tariffs and/or this Agreement shall be considered a material breach of this Agreement. For purposes of this Section modifications include but are not limited to: operating at a power factor other than specified; introduction in any manner of non -eligible energy resources to a net metered installation; connecting additional generation without notification to Company; or, other operating modes disallowed under the tariffs pursuant to which operation has been authorized. In such event, Public Service shall notify the Customer of the system's non-compliance with Public Service's tariffs or this Agreement and Customer shall have twenty (20) days from the date of such notice to either remedy the non -compliant operation or cease operation. If Customer fails to either remedy the non- compliant operation or cease operation within twenty (20) days of the date of the notice, Public Service may terminate this Agreement after ten (10) days written notice to Customer. J) Permits and Approvals: The Customer shall obtain all applicable environmental and other applicable permits from governmental authorities as required by law prior to the construction of the Generation System.

Limitation of liability A) Each Party shall at all times indemnify, defend, and save the other Party harmless from any and all damages, losses, claims, including claims and actions relating to injury or death of any person or damage to property, costs and expenses, reasonable attorneys' fees and court costs, arising out of or resulting from the Party's performance of its obligations under this agreement, except to the extent that such damages, losses or claims were caused by the negligence or intentional acts of the other Party. B) Any liability of either Party to the other for failure to perform its obligations under this Agreement shall be limited to the amount of direct damage actually incurred. In no event shall either Party be liable to the other Party for any punitive, incidental, indirect, special, or consequential damages of any kind whatsoever, including for loss of business opportunity or profits, regardless of whether such damages were foreseen. C) Notwithstanding any other provision in this Agreement, with respect to Public Service's provision of electric service to any customer including the Customer, Public Service's liability to such customer shall be limited as set forth in Public Service's tariffs and terms and conditions for electric service, and shall not be modified or in any manner affected by the terms of this Agreement. X. Dispute resolution A) Each Party agrees to attempt to resolve all disputes arising hereunder promptly, equitably, and in a good faith manner. B) In the event a dispute arises under this Agreement, and if the Parties cannot resolve it within five (5) days after written notice of the dispute to the other Party, the Parties may mutually agree to submit the dispute to mediation by a mutually acceptable mediator or dispute resolution service, in a mutually convenient location in the State of Colorado. Each Party will be responsible for one-half of the cost paid to neutral third -parties. C) The Parties agree to participate in good faith in the mediation or resolution process. If the Parties are not successful in resolving their dispute through mediation or the dispute resolution process, then the Parties may refer the dispute for resolution to the Commission, which shall maintain continuing jurisdiction over this Agreement. XI. Insurance A) At a minimum, in connection with the Customer's performance of its duties and obligations under this Agreement, the Customer shall maintain, during the term of the Agreement, general liability insurance with a combined single limit of not less than 1) Two million dollars ($2,000,000) or greater, as mutually agreed to by the Parties, for each occurrence if the Gross AC Nameplate Rating of the Generation System is greater than 2 MW. 2) Two million dollars ($2,000,000) for each occurrence if the Gross AC Nameplate Rating of the Generation System is greater than 500 kW and up to and including 2 MW. 3) One million dollars ($1,000,000) for each occurrence if the Gross AC Nameplate Rating of the Generation System is greater than 10 kW and up to and including 500 kW. 4) Three hundred thousand dollars ($300,000) for each occurrence if the Gross AC Nameplate Rating of the Generation System is 10 kW or less. 5) Such general liability insurance shall include coverage against claims for damages resulting from (I) bodily injury, including wrongful death; and (ii) property damage arising out of the Customer's ownership and/or operating of the Generation System under this Agreement. B) The general liability insurance required by Section XI.A shall, by endorsement to the policy or policies: (a) include Public Service as an additional insured; (b) provide that Public Service shall not by reason of its inclusion as an additional insured incur liability to the insurance carrier for the payment of premium for such insurance; and (c) provide for thirty (30) calendar days' written notice to Public Service prior to cancellation, termination, alteration, or material change of such insurance. C) Evidence of the insurance required in Section XI.A shall state that coverage provided is primary and is not excess to or contributing with any insurance or self-insurance maintained by Public Service. D) If the Customer is self -insured with an established record of self-insurance, the Customer may comply with the following in lieu of Section XI.A — C: 1) Customer shall provide to Public Service, at least thirty (30) days prior to the date of initial operation, evidence of an acceptable plan to self -insure to a level of coverage equivalent to that required under section XI.A. 2) If Customer ceases to self -insure to the level required hereunder, or if the Customer is unable to provide continuing evidence of its ability to self - insure, the Customer agrees to immediately obtain the coverage required under Section XI.A. E) The Customer shall provide Public Service a certificate of insurance evidencing the requisite coverage and provisions prior to the interconnection of the Generation System. After interconnection, Public Service may periodically request proof of current insurance coverage in order to verify compliance with the requirements of this Section Xl. Upon receipt of any such Page 4 of 11 21-02-503 SRC Generator Interconnection Agreement Colorado request, the Customer shall provide a certificate of insurance evidencing the requisite coverage and provisions. Failure of the Customer to provide timely evidence of proper insurance may result in disconnection of the Generation System pursuant to Section VIII.F. F) Failure of the Customer or Public Service to enforce the minimum levels of insurance does not relieve the Customer from maintaining such levels of insurance or relieve the Customer of any liability. G) All insurance certificates, statements of self-insurance, endorsements, cancellations, terminations, alterations, and material changes of such insurance shall be issued and submitted to Public Service Company. Applications that are submitted via an on-line submittal process such the Solar*Rewards® shall provide the insurance submittal as part of the on-line submittal.

This Project will not be using the Nationwide Programmatic Agreement among the U.S. Department of Agriculture Rural Development Programs, National Conference of State Historic Preservation Officers, Tribal Signatories, and The Advisory Council on Historic Preservation for Sequencing Section 106 (NPA). The Applicant proposes to construct an approximately 5 -megawatt alternating current (MW AC) solar facility ("Facility" or "Project") between Milliken and Johnstown in Weld County, Colorado. The proposed Project will use approximately ~37 -acres of a 125 -acre parcel located along State Highway 60 northeast of the intersection with County Road 19 (Figure 1). The Project is structured as a community solar Project, wherein local entities/customers can subscribe to the Project for solar power benefits and receive bill credits on their monthly electric bill to offset some of their electricity costs. Xcel Energy has undergone an Interconnection study and will require necessary distribution system upgrades to interconnect the Facility to their electrical system at a delivery point near the Project site. The Facility has an approximate Year 1 production estimate of 12,500,000 kilowatt hour (kWh) and will sell 100% of the total system production to residents and businesses within the Xcel Energy service territory through Xcel's Solar*Rewards Community program. The proposed Project is a ground -mounted solar system and will be utilizing equipment from Tier 1 manufacturers for the solar installation. The Applicant anticipates using Heliene 450 watt (W) solar modules for the facility. In addition, the Project will feature a single -axis tracker and Chint Power System (CPS) or equivalent inverters. When constructed, the solar system is anticipated to be no more than 15 feet high when oriented at maximum tilt and would be surrounded by a 7 -foot -tall security fence. Ground disturbing activities (e.g., pile foundations) are expected to approximately 6 feet below surface not to exceed 9 feet, though foundation design has not been initiated yet. The developer is in process of designing two access road alternatives to be negotiated, the final access road will ultimately be approved by the County during the permitting process. The first proposed access road for the project is anticipated to extend south approximately 100 ft from the Project site to State Highway 60. This access road would use an existing driveway to cross the operating railroad. The second proposed access road would extend north approximately 0.5 miles from the Project site towards County Road 48 %/% using some new construction (e.g., grading/blading) and improving existing access roads. The Applicant has executed an Engineering, Procurement, and Construction (EPC) contract with a local Colorado contractor in order to build the Facility. This work would include erecting a security fence, base foundations, and racking system before installing the solar modules and inverters. To complete the final facility commissioning, the contractor will wire the installed electrical components and work with XCEL Energy to interconnect the facility to the grid. At a later date, an Operations and Maintenance (O&M) provider will be designated to oversee and maintain the Facility. If RBS elects to fund the Griffiths 1 Solar Project, it will become an undertaking subject to review under Section 106 of the National Historic Preservation Act, 54 U.S.C. 306108, and its implementing regulations, 36 CFR Part 800. RBS defines the area of potential effect (APE), as an area that includes all Project construction and excavation activity required to construct, modify, improve, or maintain any facilities; any right-of-way or easement areas necessary for the construction, operation, and maintenance of the Project; all areas used for excavation of borrow material and habitat creation; all construction staging areas, access routes, utilities, spoil areas, and stockpiling areas. Impacts that come from the undertaking at the same time and place with no intervening causes, are considered "direct" regardless of its specific type (e.g., whether it is visual, physical, auditory, etc.). "Indirect" effects to historic properties are those caused by the undertaking that are later in time or farther removed in distance but are still reasonably foreseeable. Based on this definition, GSPP proposes that the APE for the referenced project consist of ~37acres within the limit of disturbance and one of the two proposed access roads as shown on the enclosed map (Figure 2). The Project is located within a plowed agricultural field and previous ground disturbance is expected throughout the APE. The surrounding viewshed is previously impacted by existing powerlines along State Highway 60 and west of the Project. The geographic scope of the APE will not be final until a determination is made by RBS pursuant to 36 CFR § 800.4(a)(1). Additionally, the APE does not include any federal and/or tribal lands as defined pursuant to 36 CFR § 800.16(x). Pursuant to 36 CFR § 800.2(c)(4), and 7 CFR § 1970.5(b)(2) of the regulations, "Environmental Policies and Procedures" (7 CFR Part 1970), RBS has issued a blanket delegation for its applicants to initiate and proceed through Section 106 review if there is agreement. In accordance with this blanket delegation, GSPP is initiating Section 106 review on behalf of RBS. In delegating this authority, RBS is advocating for the direct interaction between its borrowers and the State Historic Preservation Office (SHPO). RBS believes this interaction, prior to direct agency involvement, will support and encourage the consideration of impacts to historic properties earlier in project planning. In accordance with 36 CFR § 800.4, a representative of a Weld County is entitled to participate as a consulting party to ensure that historic properties are taking into consideration at all levels of planning and development. Should Weld County elect to participate in Section 106 review of the referenced Project, please respond within 30 days of your receipt of this request to Ashleigh Knapp at TRC (970- 593-2395 and aknapp trccompanies.cam), Elizabeth Price at GSPP (203-496-8950 and eprice@gspp.com), and/or Elaine Moran at USDA RD (Llaine4 Moran cousdla. _ ov). 4) TRC Sincerely, Ashleigh Knapp Archaeologist TRC Environmental Enclosure(s): CC Figures 1 and 2 Elaine Moran (USDA RD) Dawn DiPrince (SHPO) Elizabeth Price (GSPP) TRC LEGNED Proposed Project Area 6th Prime Meridian, Township 4N, Range 67W, Section 3.

I had the chance to meet with the landowner to discuss this yesterday, and he is potentially interested in annexing the property into Milliken, but he needs some time to think through the decision and consider all of his options (Johnstown was also interested in annexing). So the plan he and I came up with is that we are going to continue permitting the solar projects with Weld County while he and his family figure out what is best for them in the long term (at some point, he will likely be reaching out to you to set up another meeting to discuss this) and then make the final annexation decision after our USR process with Weld is complete. So, for the time being, we are going to continue pursuing a USR permit from Weld, but we want to stay in touch about the annexation. Let me know if you have any questions or want to discuss this further. https://mail.google.com/mail/u/0/?ik=230bff7673&view=pt&search=all&permthid=thread-P/03A1727585649847847929&simpl=msg-P/03A172758564984... 1/2 Notice of Inquiry Weld County Pre -application Case # PRE22-0043 Date of Inquiry 3/9/2022 Municipality Johnstown CPA Name of Person Inquiring Zachary Brammer Property Owner Arthur M.
