These plans require utilities to purchase electricity from low -carbon and cost competitive energy sources such as solar PV generation. It is evident there is a need for lower cost solar energy in the state, which currently accounts for only 3% of Colorado's electricity supply, to replace existing aging and expensive traditional energy sources. This is reflected in many utilities' interim and long-term ERP targets, which encourage investment in the most advanced, cost-effective, and emission -free technologies such as solar energy. These same goals tie directly into Weld County's plans and economic goals. The Janus Solar Project's ("Project") commissioning date scheduled for 2026 will help Weld County achieve its economic development mission to "Create a region with a healthy and sustainable economy that creates wealth, preserves the quality of life, and improves the standard of living for area residents. The Project has the effect of facilitating and attracting investment, creating new job opportunities, stimulating income growth and expanding the local community tax base" (Strategic Plan 2022-2026). The Project specifically supports Weld County's Economic Development Goal #1 to "Encourage... the location of new industries that will provide employment opportunities in Weld County" and Weld County's Economic Development Goal #2 to "Support and facilitate public and private economic development efforts that are consistent with the Goals and Policies of Weld County." As a "utility -scale" project, the electricity generated will be fed to the transmission system through wholesale transactions. The co -located battery energy storage system ("BESS") will enable production to be delivered also at nighttime during peak hours. This electricity will be used to meet the needs of Weld County's rising electricity demand. Operating at its maximum nameplate capacity of 80 megawatt alternating current (MWAc), the Project will have the capacity to produce enough energy to power approximately 17,000 typical Weld County homes. In addition to providing clean electricity, the Project will contribute to the creation of local construction jobs, supporting communities most impacted by the transformative energy landscape. This strong nexus to community needs is reflected in the broad landowner and overall community support for the Project, as detailed throughout this Application. The Project recognizes the utmost importance of using best practices for land management, protecting the local ecosystem, engaging with stakeholders and the local community, and complying with transparency to ensure the ultimate net benefit to the community. 1.3 PROJECT OVERVIEW Horus proposes to construct, operate, and decommission the Janus Solar Project, a 700 -acre 80 MWAc PV solar project. The Project will also have potential for up to a 20 MWAc BESS and substation. The proposed Project consists of single -axis tracking ground -mounted solar arrays and associated infrastructure sited within private land in southeast Weld County. The Project is adjacent to the proposed Prospect Solar Project (a 1,500 acre, 199 MWAc solar project) also to be developed by Horus and permitted through the Weld County 1041 and USR process. The equipment in this Project facility system includes solar panels, racking equipment, underground collection lines, a battery energy storage system, a step-up substation, transformer, and maintenance Wage HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application facilities. The Project will connect directly to the Sand Creek 115 kilovolt (kV) Switching Station via a short (0.2 mile) 115 kV Generation Tie Line.

Wage HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application 3 PROJECT DESCRIPTION As described in Section 1.4 Project Overview, the Project consists of PV panels affixed to a mounting structure which tracks the sun on a single axis. The Project also contains a lithium -ion based BESS that is coupled to the solar plant by direct current (DC). The BESS is capable of delivering up to 20 MW for four hours ("'80 MWh). The details for the auxiliary supply have yet to be determined The DC output of the panels and/or batteries is delivered to 23 FS4200M Power Electronics inverters where it is transformed to 34.5 kV alternative current (AC) via the associated step-up transformer on each inverter skid. The output of the inverters is collected by four 34.5 kV feeders to a collector step-up substation with a 34.5/115 kV transformer. The high side of the step-up substation is connected to the Point of Interconnection (the Sand Creek 115 kV Switching Station) via a short (<0.1 mile) 115 kV Generation Tie Line. Auxiliary power from the local distribution network will supply power to both the monitoring system, PV system, and BESS inverters when they are not in use. 5I"age HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application 4 COMPLIANCE WITH 1041 PERMIT APPROVAL CRITERIA (21-7-350) The Board of County Commissioners shall approve an application for permit for site selection and construction of a major facility of a public utility (with reasonable conditions, if any, in the discretion of the Board of County Commissioners) only if the proposed site selection and construction complies with the following criteria. 4.1 HEALTH, WELFARE, AND SAFETY (21-7-350.0.1) The health, welfare, and safety of the citizens of the County will be protected and served. The Project will protect and serve the citizens of Weld County through intentional designs to reduce and mitigate environmental impacts to wetlands, wildlife, and agricultural resources within the Project site. The Project strives to make environmental quality a priority by siting away from and reducing impacts to water features, wildlife, and associated habitats to the greatest extent possible. The Project Site is located in a relatively remote and rural setting and is sparsely populated. A security fence will be constructed around the perimeter of the Project to prevent the public from entering the area. During construction, it is anticipated that a minimal amount of particulate air pollution will occur due to construction traffic on dirt roads. The site is generally flat and only spot grading is anticipated, thereby reducing dust. To address potential dust creation from the Project, a Dust and Weed Mitigation Plan (Appendix D) and Environmental Protection Measures (Appendix E) have been developed. Actions in the Dust and Weed Mitigation Plan for the Project include moistening the soil, spraying the roads with a dust suppressant or binder (magnesium chloride and lignin mixture), monitoring for fugitive dust, creating buffers between the neighboring properties, and post construction re -vegetation of disturbed areas with a county approved seed mix. Additionally, a Preliminary Drainage Analysis (Appendix J) found that the mitigation basins and re-establishment of native vegetation will allow for reduced run-off and potentially mitigate flooding risks around the immediate area. Temporary construction -related noise and disruption will occur during project construction. The loudest construction noise will occur during construction pile driving of 89 - 95db(A) and equipment backup beeping (reverse warning sounds) of 97-112 db(A). This noise will be temporary in nature and is not anticipated to exceed maximum levels at the property boundary for construction activities outlined in Weld County noise ordinances set forth in Chapter 14 Article IX of the Weld County Code. For reference, Weld County's Code limits maximum noise from 7:00 a.m. — 9:00 p.m. to not exceed 80 dB(A) and from 9:00 p.m. — 7:00 a.m to not exceed 75 dB(A)as measured at the boundary of the property from which the noise complaint is made. Any debris produced during construction will be promptly removed and disposed of properly by the construction contractor. There will be no air pollution, water pollution, noise, or debris creation during the operational phase. The operation of the Project will generally be controlled remotely from the operator and local utility central control centers. During normal operation, the solar field and substation may be accessed by the operator and utility personnel to conduct routine inspections or maintenance, with limited dust creation and negligible effects to local roadways. Operations and maintenance work is Wage HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application typically done monthly and lasts only a few days, not requiring a full-time presence of more than 1-2 workers. No long-term consequences to public health, welfare and safety will result from construction or operation of the Project. The transition to a renewable energy economy has long-term beneficial health impacts such as improvements to regional air quality through the reduction of higher polluting energy sources. The Project will contribute to the overall health and welfare of the community through active land stewardship and native plant restoration. 4.2 NATURAL AND SOCIO-ECONOMIC ENVIRONMENT (21-7-350.C.2) The natural and economic environment of the County will be protected and enhanced. Natural Protection and Benefits The proposed layout for this project was developed based on an iterative design process, including consideration of environmental and physical constraints, stakeholder feedback, local and national engineering and planning requirements, and Weld County's permitting processes. Several studies have been conducted to best assess and mitigate the Project's environmental impacts. These studies are included in Appendix Q— Additional Supporting Studies and include the following: • Class I Cultural Resources Report • Wetland and Waterbody Delineation Report • Technical Memorandum for Protected Species Report • Phase I Environmental Site Assessment Report (digital only due to size of document) • CIA The resulting layout avoids wetlands, waterways, and sensitive species. Environmental protection measures have been developed in coordination with agency outreach and are presented in Appendix E — Environmental Protection Measures and Agency Coordination. The existing site land use is dryland agricultural row crops and rangeland, most similar to tillage/agricultural land classification, which does not exhibit the characteristics of a low -impact development. Vegetation actions include seeding the land with a county approved seed mix to promote the growth of native grasses to preserve the quality of the soil and mitigating noxious weeds within the Project site. By utilizing the county approved native grass seed mix below the panels, the existing tillage/agricultural land areas will be changed to a heavy meadow land classification that reduces peak flow rates and manages stormwater in line with the historic conditions of the site. The site design promotes conservation design at both the watershed and site levels, with the goal of replicating the native hydrologic characteristics of the sub -watersheds, creating natural ground coverage, and minimizing proposed grading and compaction. Preserving agricultural resources has been a long-standing priority for both Weld County and participating landowners like Beth and Harold Erker, a multigenerational farming family. Within the parcels involved in the Prospect and Janus Project Sites, approximately 91% are considered Prime Farmland if irrigated (or Mage HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application with other soil/climactic conditions) and 3% are considered Farmland of Statewide Importance. * Converting the land use from dryland agriculture to photovoltaic solar is akin to the USDA Farm Service Agency's Conservation Reserve Program. Through the Conservation Reserve Program, farmers voluntarily e nroll to remove land from agricultural production for a decade or more, allowing the soil to rest, improve water quality, prevent soil erosion, and enhance wildlife habitat. Between 2017-2021 the Conservation Reserve Program contributed $29 million to Weld County farmers who in return installed pollinators, n ative grass plantings, and habitat buffers on 29,090,876 acres of private land (EWG 2023). Similarly, during the life of the Project, long-term resource -conserving perennial grasses and forbs will improve soil fertility and reduce erosion, weeds will be mitigated, fertilizers will be removed to improve water quality, and riparian buffers are enhanced to benefit wildlife. In return, Horus will provide landowners with rental payments and cost -share assistance during the life of the Project. Pile driving solar panel racking into the n ative soil profile with minimal grading allows properties to return to enhanced agricultural productivity following decommissioning — making utility -scale solar one of the only land uses that enhances prime soils and regional agriculture long-term. Water usage is a great concern for Weld County and Horus is committed to protecting Weld County's waterways and supply. The properties involved in this project have no vested water rights. The project has secured sufficient water resources from a private water service provider to supply what will amount to relatively modest water needs for the Project (0.007 -acre feet per acre per year). As compared to many other uses shown in Figure 1, solar requires minimal water for project operation. The Project's water use plan is intended to preserve the agricultural base of the community and allow for a return to full agricultural and other use of water resources once the solar project is decommissioned. For planning purposes, Project water needs can be divided into the following categories: 1. Construction/Dust Control — Some water will be required to implement the dust control plan and related aspects of the construction phrase. This water may be supplied by outside service companies as part of their spray mix system and may not require any contribution of local water from the area. There will also be stormwater controls and related mitigation measures during construction to manage existing surface water flow and maintain water quality, as required by governing regulations. Finally, some water may be needed for initial planting and maintenance of plants used for screening, although species are selected for their minimal ongoing watering requirements. 2. Fire Control — While this Project presents minimal fire risks, Horus has committed to assisting local fire control authorities in ongoing fire control activities by adding a designated water tank for general fire control purposes. This tank will need to be filled periodically through a private water supplier. 3. Panel Washing and Maintenance — On an ongoing basis, the only water supply needed for the Project is for washing and maintaining the solar panels and supporting facilities, in part to maximize energy return. The exact cleaning schedule is a function of precipitation, dust, and other particulate settling on the panels. To minimize cleaning, the Project intends to utilize a commercial contractor to treat neighboring roads with GMCO CS products, a blend of liquid *Data limited to parcels within project boundary. Similar data on Site Plan includes displayed buffer data. Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application magnesium chloride and a complex sugar. The product is an environmentally friendly solution for gravel road stabilization and dust control. This will reduce water consumption related to cleaning during the operation period. Water needs will be more than adequately met by (1) the occasional purchase or trucking in of outside water where needed, particularly at the construction phrase, and (2) water purchase through a private water supplier. While fire is not a typical concern for PV and BESS systems, the Project's water tank may be utilized by the Southeast Weld Fire District and will provide a key resource for protection against fires in the region, especially in times of drought.

Setbacks and corridors have been established to preserve the natural resources and connect habitats that do occur on site. Through correspondence with U.S. Fish and Wildlife Service and Colorado Parks and Wildlife (CPW), it was confirmed that the Project site will not be a concern for interfering or disturbing potential habitat for listed species and existing species on the property. To mitigate effects on the local wildlife, a 250 to 500 -foot wildlife corridor has been incorporated into the design plan (Prospect Solar). Overall, there are not any expected to be significant effects on wildlife habitat or endangered wildlife species. Mage HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application Socio-Economic Benefits The Project offers numerous socio-economic and other advantages to the community. The Socioeconomic Impact and Community Benefit Report (Appendix F) found that solar energy is a responsible and excellent use of private land, delivering very low environmental impacts combined with high social and economic benefits. It is estimated that the Janus Solar Project, in combination with the Prospect Solar Project, will support 1,977 full-time equivalent direct and indirect jobs, and produce nearly $13 million in projected property tax revenue. Economic output during the 12 -18 -month construction phase is estimated to be $171,955,000 and $8,229,700 during the operating life of the Janus and Prospect Solar Projects. The full report can be found in Appendix F. 4.3 REASONABLE ALTERNATIVES (21-7-350.C.3) All reasonable alternatives to the proposed action, including use of existing rights -of -way (ROWs) and joint use of rights -of -way (ROWs) wherever uses are compatible, have been adequately assessed and the proposed action is compatible with and represents the best interests of the people of the County and represents a fair and reasonable utilization of resources in the impact area. All reasonable alternatives within the study area were thoroughly assessed to make the Project fully compatible with and representative of the best interests of the people of Weld County. While a larger land area was initially studied, the Project's 700 -acre final footprint was selected because it offered advantages to the community and overall environment while providing opportunities and circumstances favorable to Solar and BESS facilities, specifically 1) ample undeveloped flat land, with the ability to accommodate various layouts of PV solar and the incorporation of appropriate setbacks, 2) existing transmission infrastructure less than 0.2 miles from the property, 3) augmenting, while sustaining for future landowners, current unsustainable primary land use as indicated by the landowners. 4.4 FAIR AND REASONABLE UTILIZATION OF RESOURCES (21-7-350.C.4) The proposed action is compatible with and represents the best interests of the people of the County and represents a fair and reasonable utilization of resources in the impact area. Strong landowner support is indicated through the letters included in the Public Outreach Summary in Appendix H and demonstrates the compatibility of the project with the best interests of those in the County closest to the project. Utilization of local resources within Weld County will be minimal as the Project will not require services such as water, sewage, or emergency services at a level typical of other land uses in the area. Overall, the proposed Project will be a low water -use development, with water only being used as outlined in Section 4.2 Natural and Socio-Economic Environment. During construction, personnel will use portable sanitary units and carry in drinking water. A septic system is unnecessary for the operation of the Project and has not been incorporated into the site design. However, if desired a septic system may be installed on -site and would be permitted and installed in compliance with Weld County Code by a licensed septic installer. The Project site is located within District 3 of the Weld County Sheriff's Department and is within the jurisdiction of the Southeast Weld Fire 10I Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application Protection Districts. No impacts to these districts are anticipated from construction and operation of the Project. Construction of the project will require the use of existing roads and highways. In exchange for this resource use, Horus will submit a Road Use Agreement / Access Road Permit application that will comply with all County design standards following approval of this Permit application. A Traffic Impact Narrative in Appendix G found that the temporary construction related vehicle traffic for this project can be accommodated by the existing roadway system. Haul routes for the Project are outlined in the Traffic Impact Narrative. During the operation phase, as referenced in the Traffic Study, the unmanned facility will generate a negligible number of lightweight trucks and cars for routine and periodic maintenance trips. The public street roadways and adjacent intersections are anticipated to successfully accommodate this project traffic volume. The Project will generate increased resources in the form of energy that may be utilized throughout the region. The local economy will be stimulated through employment of Weld County's workforce resources during the construction period. Non -local workers will use local resources by staying in hotels, motels, and other temporary housing; eating at restaurants; and shopping at local businesses, providing benefits to the local economy. Please refer to the Socioeconomic Impact and Community Benefit Report (Appendix F) for more information on economic impacts. 4.5 ADVERSE IMPACTS (21-7-350.C.5) A satisfactory program to mitigate and minimize adverse impacts has been presented, including decommissioning and reclamation. Horus is dedicated to creating a program to minimize potential adverse impacts from this Project. To support this vision, Horus conducted thorough property examination to inform the siting process including consideration of visual impacts, wildlife resources, sensitive soils, wetlands and waterways. Public outreach efforts included individual neighbor meetings, a neighbor open house, and project website (https://prospectandjanussolar.com/). These interactions are continuing and will be a critical element throughout all phases of the project. The neighbor open house meeting was held on July 5, 2023, and hosted landowners, tenants, and neighbors within 1,000 feet of the Project Site, as well as community partners from across the region. The goal for the meeting was to share information with and hear feedback from neighbors and local community, so that their questions and concerns could be factored into how Horus proceeds forward. Follow up notifications regarding the project were sent in August to ensure that all neighbors had a chance to review the project and have their concerns addressed prior to application submittal. These ongoing communications and interactions have resulted in significant mitigation and improvement actions which have continued to build widespread project support. The following actions to mitigate adverse impacts were identified and will be implemented: 11 'Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application • Environmental protection measures have been developed to avoid, minimize, or mitigate adverse impacts during engineering, construction, and operation and are presented in Appendix E - Environmental Protection Measures and Agency Coordination • Horus has prioritized communication with the local community as outlined above and in the Public Outreach Summary in Appendix H. Horus Energy has proposed a living property fence bordering the Project in response to this outreach effort. • Visual simulations were conducted to aid mitigation of neighbor concerns about the visual appeal of the project. See Appendix I - Visual Impact Analysis. • Protection from erosion will occur through implementation of best management practices. See Preliminary Drainage Analysis in Appendix J. • Incorporation of a wildlife corridor (Prospect Solar) and setbacks from sensitive habitat will minimize adverse effects to wildlife. See Appendix Q - Technical Memorandum for the Protected Species Report and the CIA in Appendix N. • Native plant seeding will be incorporated between and around the solar arrays to beautify and restore the appearance of the Project site and to promote the return of native species and pollinators. This plan will also preserve and improve soil conditions. • A Dust & Weed Mitigation Plan is included in Appendix D. • The development of a Decommissioning Plan (see Appendix K) will return the site to its pre- existing conditions within 12 months of operation cessation. Monitoring and site restoration may extend beyond this period to ensure successful revegetation and rehabilitation. • Various individual studies relating to the Project, such as the Glint and Glare study, were shared for feedback from individual landowners with particular interest in these matters. 4.6 MASTER PLAN COMPLIANCE (21-7-350.C.6) The nature and location or expansion of the facility complies with all applicable provisions of the master plan of this County and service areas, and other applicable regional, metropolitan, state and national plans as shown in the table below.

The Project will have no demand for additional community resources or unduly impact existing community resources. Refer to Section 4.4 Fair and Reasonable Utilization of Resources for more detail. 4.8 UNDUE INTERFERENCE (21-7-350.0.8) The nature and location of the facility or expansion will not unduly interfere with existing easements, rights -of -way, other utilities, canals, mineral claims or roads. The Project is not anticipated to unduly interfere with existing easements, ROWs, other utilities, canals, or mineral interests. Horus has and will continue to negotiate easements or other access agreements on a willing seller basis and does not anticipate difficulties in obtaining such rights, especially given those landowner agreements already obtained. In addition, Horus has designed the Project to not unduly interfere with other access rights. Potential haul routes and access points are shown on the Five -Mile Vicinity Map in Appendix A and a Traffic Impact Analysis is included in Appendix G. Existing easement agreements can be found in Appendix L. The Project will maintain minimal impact on usage of utilities during construction. Please refer to Section 4.7 Demands for Government Services and Fair and Reasonable Utilization of Resources in Section 4.4 for a discussion on utility use. Canals and other irrigation channels will be considered with construction of the Project. Current irrigation pathways and ditches have been marked and planned around within the site plan. These structures and channels will be preserved on the property for possible future use of agriculture following the decommissioning of the project. According to the State of Colorado Energy and Carbon Management Commission (ECMC) maps, seven well bore permits have been filed on the site. The Project is sited to avoid existing oil and gas facilities and pipelines, surface use agreements, and reasonably accommodates mineral access through appropriate setbacks that have been incorporated into project design. In addition, the Project site is in a low oil and gas producing area in the County. All wells on site have expired and no site reported any production to the ECMC. Mineral estate owners were identified through a list provided by the Weld County Clerk and Recorder. The Applicant is communicating with these owners to obtain Surface Use Agreements (confidential) and will incorporate mineral access locations to the site plan if requested by the mineral owners during the course of those discussions. The proposed Project is a "qualifying surface development" located in the Greater Wattenberg area (T2S to T7N — R61W to R69W) therefore written certification required by Section 24-65.5-103.3, C.R.S. (notice to mineral estate owners) will be provided on the date of the initial public hearing. 151Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application 4.9 UTILITY ADEQUACY (21-7-350.C.9) Adequate utilities exist or shall be developed to service the site, as necessary. As previously discussed in Section 4.4 Fair and Reasonable Utilization of Resources, the Project will have minimal and negligible needs for utility services and will provide an increase of clean, affordable, and locally produced energy. 4.10 WILDLIFE, NATURAL RESOURCE, AND HISTORIC LANDMARKS (21-7-350.0.10) The nature and location for expansion of the facility will not unduly interfere with any significant wildlife habitat or adversely affect any endangered wildlife species, unique natural resource or historic landmark within the impact area. Future expansion is not anticipated for this Project; therefore, this section is not applicable. 4.11 GEOLOGIC AND TOPOGRAPHIC FEATURES (21-7-350.0.11) The geological and topographic features of the site are adequate for all construction, clearing, grading, drainage, vegetation and other needs of the facility construction or expansion. The Project site is located within an ideal area for construction of PV solar based upon the geological and topographic features of the property. The Project is located within the U.S. Geological Survey Prospect Valley and South Roggen topographic quadrangles, which is within the Colorado Piedmont physiographic province, and is characterized by prairies and mostly unconsolidated sediments. The Project has been sited on mostly flat terrain; therefore, minimal site grading is expected. Localized soil stripping will be required for the inverters, substation, laydowns, and yards. This topsoil, along with the soil from the stormwater ponds, will be stockpiled on site to form the berm located on the Project boundary with parcel APN 14793000001 owned by Mr. Erker. No soil stripping is planned under panels nor at the screw pile locations, unless required to smooth out localized knolls and depressions, or to facilitate appropriate stormwater runoff. Furthermore, drainage and vegetation will be preserved and promoted throughout the Project site, with site plans built around the existing Sand Creek and West Sand Creek. More information on the adequacy of drainage, including soil class, can be found in Appendix J — Preliminary Drainage Analysis. Information on dust/weed mitigation is outlined in Appendix D — Dust and Weed Mitigation Plan. Soil class and avoidance areas are also shown on Appendix A — Maps and Figures: Plot Plan. 4.12 WATER QUALITY (21-7-350.0.12) The existing water quality of affected state waters will not be degraded below state and federal standards or established baseline levels. A formal wetland and waterbody field delineation survey was conducted in October 2022 to identify and delineate the boundaries of wetlands and waterbodies within the Project site. The results of this survey are presented in Appendix Q - Supporting Studies: Wetland and Waterbody Delineation Report. The 16I Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application Project has incorporated buffers to protect and preserve the wetlands and waterbodies (See Appendix A - Maps and Figures: Plot Plan). The Project will include setbacks per state mandates for all wells, active or abandoned, to ensure no contamination or impacts to surface waterways or ground water. No discharge of contaminants or other materials will occur to state waters as a result of this Project. Following land use permitting, but prior to construction, the project will obtain a Construction Stormwater Permit from Colorado Department of Public Health and Environment (CDPHE). A preliminary drainage analysis was conducted and under the current design, no erosion harm from the construction of the Project is expected. The offsite drainage patterns will remain the same as historic conditions. See Appendix J — Preliminary Drainage Analysis. 4.13 STREAMS, LAKES, AND RESERVOIRS (21-7-350.0.13) The proposed project will not have a significantly adverse net effect on the capacities or functioning of streams, lakes, and reservoirs in the impact area. Please refer to the discussion in Section 4.12 - Water Quality. 4.14 BENEFITS OUTWEIGH LOSSES (21-7-350.0.14) The benefits of the proposed developments over the life of the project outweigh the temporary losses of any natural resources or reduction of productivity of agricultural lands as a result of the proposed development. During the life of the Project, the land will be rested and preserved for future agriculture. While the installation of a solar facility changes the land use of the property in the short term, planting grasses and other low -growth species beneath the panels and in turn managing weed growth and reducing soil erosion e nhances the soil fertility. Thus, any loss of natural resources or agricultural productivity will be negligible, and at the time of decommissioning, the land will be restored to its previous condition or intended future u se. Additional benefits from the proposed solar farm include: • Production of renewable energy will strengthen the energy supply portfolio of the region, • Support of regional interests to deploy more renewable and clean energy, helping the state and local communities achieve Colorado energy goals, • Job creation during construction and indirect economic benefits as described in Section 4.2 - Socio-Economic Benefits, • Support of private landowners' rights as stewards of their own land, • Supplementation of landowner income without detrimental effects to land and resources, • Environmentally and socially responsible land use as outlined throughout this application, Specifically: o Sensitive areas avoidance, o No hazardous waste, o Water conservation, 17I Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application o Minimal need for government services, o Preservation of agricultural land for future use, o Promotion of soil conservation and land stewardship, o Improvements to regional air quality through emission reductions from primary energy providers. 4.15 PROPERTY RIGHTS, PERMITS, AND APPROVALS (21-7-350.0.15 & 23-2-260.E.3) The applicant has obtained or will obtain all property rights, permits and approvals necessary for the proposed project, including surface, mineral access rights and easements for drainage, utilities, access, etc. If the applicant has not obtained all necessary property rights, permits and approvals, the Board may, at its discretion, grant the permit conditioned upon completion of the acquisition of such rights prior to issuance of a building permit by the County.

Copies of the executed assignments will be provided upon receipt. All land rights will be recorded with the Weld County Clerk and Recorder prior to construction. Horus will not obtain a building permit until all final required land use rights and permits have been secured. Horus is in the process of obtaining the necessary ditch agreements and County Road ROW access permits for the Project. Project access will be determined after final site plans and approval of this permit application including copies of any access or ROW agreements active by the date of the application for such access. No water rights, easements for drainage, disposal, or utilities are necessary for the Project. See Section 9 - List of Future Permits and Plans. 4.16 TOXIC AND HAZARDOUS SUBSTANCES (21-7-350.C.16) The proposed project will not present an unreasonable risk of exposure to or release of toxic or hazardous substances within the impact area. The proposed project will not present an unreasonable risk of exposure to or release of toxic or hazardous substances within the Project site. The solar modules are composed solely of solid materials, contain no cadmium, and a small amount of lead that is well under Federal limits and much less than is found in a typical cell phone. During operation, maintenance will generally include only inert substances such as water for washing the panels. No fuel or raw materials will be stored onsite during operations. During construction, fuel, raw materials, equipment, and related items will be maintained per a Spill Prevention, Control, and Countermeasures (SPCC) Plan. The contractor will prepare and adhere to the SPCC Plan to ensure that petroleum products and hazardous materials are managed appropriately. Compliance with U.S. Environmental Protection Agency (USEPA) Resource Conservation and Recovery Act (RCRA) laws governing the proper management of solid and hazardous waste will be closely followed for all waste disposal. The SPCC Plan will ensure that liquids and gases used in construction will be contained and managed in accordance with county, state, and federal requirements (Section 5.4.5 - Hazards and Emergency Procedures). See Appendix E for applicable Environmental Protection Measures and Agency Coordination. See Appendix M for the Project Emergency Management Plan. 18I Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application The Project will also include the construction of a BESS. The BESS is lithium ion based and from an established manufacturer (such as TESLA).

To protect the health, safety and welfare of the public, the substation and transmission line will be constructed in accordance with all applicable State and federal laws and regulations. Appendix M presents the Emergency Management Plan which includes information regarding response procedures for utility emergencies. The Project will comply with Colorado Public Utilities Commission (CPUC) requirements regarding electromagnetic field (EMF) levels adjacent to the transmission line ROW. The CPUC EMF limits are 150 milligauss at the edge of the ROW, one meter above ground. The Project's transmission line alignment will be designed to limit potential human exposure to EMF. Environmental damage and contamination due to materials used at or activities taking place at the proposed facility. Only minimal chemical materials will be used for onsite activities. As discussed above, an SPCC plan will be developed and followed for oil related materials. Substation equipment can contain oil. The hazards are the flammability of heated oils and the danger of energized equipment and are the responsibility of the substation operator. Secondary containment will be implemented in applicable areas with berms and other appropriate measures. The BESS will not pose any risks to the public. Additional precautionary measurements have been taken in coordination with the Southeast Weld Fire District to ensure the safe installation and operation of the facility. Enclosed containment will be provided for all trash to control blowing debris and other potential nuisance conditions. All construction waste, including trash and litter, garbage, sanitary waste, other solid waste, petroleum products, and other potentially hazardous materials will be removed from the site and transported to a disposal facility authorized to accept such materials. The only hazardous chemicals expected to be used onsite are those found in diesel fuel, gasoline, coolant (ethylene glycol), and lubricants in machinery during the construction phase of the project. Hazardous materials will not be released onto the ground or into streams or drainage areas. Construction activities will comply with all applicable federal, state, and local laws and regulations regarding the use of hazardous substances.

The CIA in Appendix N addresses hydrologic, geologic, pedologic, and biotic impacts. As discussed throughout this application, Horus has worked extensively with neighbors and all involved parties and agencies to satisfy concerns regarding their views of the Project. Mitigation measures include integration of appropriate setbacks and natural barriers where appropriate. See Appendix I - Visual Impact Analysis and Appendix H - Public Outreach Summary. No discernable noise will occur from the solar panels during project operation. Some project facilities, such as inverters and BESS equipment, will produce low levels of noise. However, these facilities will be located at least a quarter mile from residences and noise levels will be well below levels set by County noise ordinances. High noise levels are anticipated to occur during construction pile driving operations. This noise will be temporary in nature and is not anticipated to exceed maximum levels for construction activities outlined in Weld County noise ordinances set forth in Chapter 14 Article IX of the Weld County Code. No odor will be created during operation/construction of the Project. 5.11 SURFACE DRAINAGE ANALYSIS (21-7-330.B.12) Ground -mounted solar collector systems shall be exempt from impervious surface calculations if the soil under the collectors is not compacted and maintained in vegetation with a county approved seed mix (21- 7-340.G). Under current designs, no undue erosion harm from the construction of the project will occur, as shown in the Preliminary Drainage Analysis in Appendix J. Per prior discussions with Weld County personnel referenced above, a full drainage report is not necessary for a complete application. 5.12 DUST AND WEED MITIGATION PLAN (21-7-330.6.13) Horus has worked with local partners to develop a Dust Management Plan that will lessen the impact of construction activities. Horus plans to contract with Road Running Grading to suppress dust from roads through the application of magnesium chloride and lignin. This dust suppressant will last 8 to 12 months before the mixture needs to be resprayed. Dust and Weed Mitigation Plan has been included in Appendix D. 5.13 FLOODPLAIN MAPPING (21-7-330.6.14) There are no Federal Emergency Management Agency recorded floodplains or history of floodplains within the Project site. 251Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application 5.14 DECOMMISSIONING/RECLAMATION PLAN (21-7-330.B.15) The development of a Decommissioning Plan (see Appendix K) will return the site to its pre-existing conditions within 12 months of operation cessation. Monitoring and site restoration may extend beyond this period to ensure successful revegetation and rehabilitation. 5.15 OTHER INFORMATION (21-7-330.6.16 & 23-2-260.C.17) No additional information is necessary for this Application or was required by the Planning Department at the pre -application meeting. See Section 8 USR Questionnaire, below. 5.16 WAIVER OF SUBMITTAL REQUIREMENTS (21-7-330.C) Due to the size of these projects and based on industry standards, it was recommended that a scale of 1" = 200' should be used for the plot plan initial submittal. The 1" = 100' or larger scales will be reserved for specific areas of concern the County may have during the review process. Weld County Planning Services approved this waiver request on October 16, 2023. 26I Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application 6 DEVELOPMENT STANDARDS FOR 1041 SEF (SECTION 21-7-340) 6.1 HEIGHT LIMITATION (21-7-340.A) Ground -mounted solar collectors shall not exceed twenty-five (25) feet in height, measured from the highest grade below each solar panel to the highest extent of the solar panel rotation. Ground -mounted solar collectors will be less than 10 feet, measured from the highest grade below each solar panel to the highest extent of the solar panel rotation. Refer to the 1041/USR Plot Plan in Appendix A — Maps and Figures. 6.2 GLARE (21-7-340.B) 1041 SEF shall be designed, located or placed so that concentrated solar glare from its solar collectors will not be directed toward or onto nearby properties or roadways at any time of the day. A Glint and Glare Analysis was performed on the array areas of the Project. The analysis was tailored to review the potential effects of the solar farm on nearby residences and on a privately owned landing strip near the Project site. Worst -case scenario parameters were used for a conservative estimate. Findings show that with appropriate system settings, it is unlikely that glare from the proposed solar project will be problematic in any manner for the surrounding area and that the Project would pass the Federal Aviation Administration's 2021 policy regarding glint and glare effects to commercial airports. An in-depth explanation of the above conclusion and the details of the full parameters of this study are found in Appendix P - Glare Analysis. The study was shared with concerned neighbors.

The Project boundary encompasses approximately 535 fenced acres. The maximum nameplate generating capacity of the Project will be up to 96.6 megawatts (MW), alternating current (AC). Major components of the Project include solar modules, tracking systems and inverters/transformers (inverter stations). This Decommissioning Plan (Plan) provides a description of the decommissioning and restoration phase of the Project. Start -of -construction is planned for 2024, with a projected Commercial Operation Date in the third quarter of 2026. The Project will consist of the installation of the perimeter fencing; solar arrays and associated trackers, foundations, and steel piles; inverter stations; access and internal roads; electrical collection system and substation. A site layout is presented in Figure 1, Site Layout, in Appendix A, Figure. This Plan is applicable to the decommissioning/deconstruction and restoration phases of the Project. A summary of the components to be removed is provided in Section 1.1, Solar Farm Components. A summary of estimated costs associated with decommissioning the Project is provided in Section 4.0, Decommissioning Cost Estimate Summary. 1.1 SOLAR FARM COMPONENTS The main components of the Project are intended to be: • 171,825 Solar panels with 5,925 Strings • 23 DC to AC inverters • 5,573 Tracking Racks • Battery Energy Storage System (BESS) • Electrical Substation • Support Facilities 1.2 TRIGGERING EVENTS AND EXPECTED LIFETIME OF PROJECT Project decommissioning may be triggered by an event such as the end of the power purchase agreement, abandonment, or when the Project reaches the end of its operational 1 life. The Project will be considered to be discontinued use after six (6) months without energy production, unless a plan is developed and submitted to the County outlining the steps and schedule for returning the Project to service. Decommissioning will begin within 30 days after the project is considered to be discontinued as described below. Project facilities will be removed from the site in accordance with a timeframe agreed upon by Weld County. If properly maintained, the expected lifetime of a utility -scale solar facility is approximately 25 to 30 years with an opportunity for a project lifetime of 50 years or more with equipment replacement and repowering. Depending on market conditions and project viability, the solar arrays may be retrofitted with updated components (e.g., panels, frame, tracking system, etc.) to extend the life of the project. In the event that the modules are not retrofitted, or at the end of the Project's useful life, the panels and associated components will be decommissioned and removed from the Project site. The value of the individual components of the solar facility will vary with time. In general, the highest component value would be expected at the time of construction with declining value over the life of the Project. Over most of the life of the Project, components such as the solar panels could be sold in the wholesale market for reuse or refurbishment. As efficiency and power production of the panels decrease due to aging and/or weathering, the resale value will decline accordingly. Secondary markets for used solar components include other utility scale solar facilities with similar designs that may require replacement equipment due to damage or normal wear over time; or other buyers (e.g., developers, consumers) that are willing to accept a slightly lower power output in return for a significantly lower price point when compared to new equipment. Components of the solar facility that have resale value may be sold in the wholesale market. Components with no wholesale value will be salvaged and sold as scrap for recycling or disposed of at an approved offsite licensed solid waste disposal facility (landfill). Decommissioning activities will include removal of the arrays and associated components as listed in Section 1.1, Solar Farm Components, and described in Section 2.0, Project Components and Decommissioning Activities. 1.3 DECOMMISSIONING SEQUENCE Decommissioning activities will begin within 7 months of the Project ceasing operation and are anticipated to be completed in six to 12 months. Monitoring and site restoration may extend beyond this period to ensure 2 successful revegetation and rehabilitation. The anticipated sequence of decommissioning and removal activities are described below; however, overlap of activities is expected. • Reinforce access roads, if needed, and prepare site for component removal • Install erosion control fencing and other best management practices (BMPs) to protect sensitive resources and control erosion during decommissioning activities • De -energize solar arrays • Dismantle panels and racking • Remove frame and internal components • Remove portions of structural foundations and backfill sites • Remove inverter stations and foundations • Remove electrical cables and conduits • Remove access and internal roads and grade site (if required) • Remove substation • De -compact subsoils as needed, restore and revegetate disturbed land to pre - construction conditions to the extent practicable 2.0 PROJECT COMPONENTS AND DECOMMISSIONING ACTIVITIES The solar facility components and decommissioning activities necessary to restore the Project area, as near as practicable, to pre -construction conditions are described within this section. 2.1 OVERVIEW OF SOLAR FACILITY SYSTEM Janus Solar and Storage project anticipates utilizing approximately 171,825 solar modules, with a total nameplate generating capacity of approximately 111.6 MW, direct current (DC) [96.6 MW(AC)]. The Prospect and Janus Solar and Storage project area encompasses approximately 535 acres and will be bounded by perimeter fencing as shown in Figure 1, Appendix A (preliminary design; subject to modification). The land within the perimeter fencing is predominantly agricultural land. Statistics and estimates provided in this Plan are based on a Trina Solar TSM-Deg21C.20 Vertex 650 -watt panels. 3 Foundations, steel piles, and electric cabling and conduit installed below the soil surface will be removed. Access roads may be left in place if requested and/or agreed to by the landowner; however, for purposes of this assessment, all access roads are assumed to be removed. Public roads damaged or modified during the decommissioning and reclamation process will be repaired upon completion of the decommissioning phase. Estimated quantities of materials to be removed and salvaged or disposed of are included in this section. Many of the materials described have salvage value; although, there are some components that will likely have none at the time of decommissioning. Removed materials will be salvaged or recycled to the extent possible. Other waste materials will be disposed of in accordance with state and federal regulators in an approved licensed solid waste landfill. Solar panels may have value in a resale market, depending on their condition at the end of the Project life. If the Project is decommissioned prior to the anticipated 25 to 30 year timeframe, the resale value of components may be substantially higher than at the end of the projected Project. Table 2-1, Primary Components of Solar Farm to be Decommissioned, presents a summary of the primary components of the Project included in this decommissioning plan. TABLE 2-1 PRIMARY COMPONENTS OF SOLAR FARM TO BE DECOMMISSIONED Component Quantity Unit of Measure Solar Modules 171,825 Each 5,490 Tracking System Tracker Steel Piles (approximate) 27,450 Each Battery Storage Units 140 Each 7 BESS Blocks and Foundations Each Battery Inverters 7 Each Inverter Stations with Foundations 23 Each Electrical Cables and Conduits (estimated) 29,600 Linear Foot Perimeter Fencing (approximate) 35,963 Linear Foot Access Roads (approximate) 19,500 Linear Foot Project Substation 1 Each 4 2.2 SOLAR MODULES Prospect Solar and Storage are currently intending to use 650 -watt panels from Trina Solar for the Project. The modules are mainly comprised of non-metallic materials such as silicon, glass, composite film, plastic, and epoxies, with an anodized aluminum frame. At the time of decommissioning, module components in working condition may be refurbished and sold in a secondary market yielding greater revenue than selling as salvage material. 2.3 TRACKING SYSTEM AND SUPPORT The solar modules are intended to be mounted on Gamechange Solar Trackers. The tracking system is mainly comprised of high -strength galvanized steel and anodized aluminum; steel piles that support the system are assumed to be comprised of galvanized steel. The solar arrays will be deactivated from the surrounding electrical system and made safe for disassembly. Liquid wastes, including oils and hydraulic fluids will be removed and properly disposed of or recycled according to regulations current at the time of decommissioning. Electronic components and internal electrical wiring will be removed and salvaged. The steel piles will be completely removed from the ground. The supports, tracking system, and posts contain salvageable materials that can be sold to provide revenue to offset the decommissioning costs. 2.4 BESS BATTERY UNITS AND SUPPORT STRUCTURES The project includes 780 battery energy storage units, each with integrated fire suppression and ventilation. The system will provide 120 MWAc of rated power capacity and 480 MWh of energy storage capacity. Estimated quantities of material to be removed and salvaged or disposed are included in this section. All materials will be salvaged or recycled to the extent possible. All other waste materials will be disposed at an approved licensed landfill in accordance with state and federal law. The BESS units will be grouped on concrete foundations. The units are mainly comprised of lithium -ion batteries, steel, copper, plastic, and epoxies. 5 2.5 INVERTER STATIONS The inverters are intended to be Power Electronic FS4200M inverters that are mounted on small concrete footings or piers on steel piles within the array. The inverters will be deactivated, disassembled, and removed. For purposes of this report, it is assumed that piers with steel piles will be utilized. Depending on condition, the equipment may be sold for refurbishment and re -use. If not re -used, they will be salvaged or disposed of at a licensed solid waste landfill. 2.6 ELECTRICAL CABLING AND CONDUITS The Project's electrical collection system is planned to be installed above ground. All cabling will be removed and salvaged. Recovery cost has been conservatively based on aluminum wiring; however, the salvage value of copper, if used, would be far greater. 2.7 PROJECT SUBSTATION Prospect and Janus Solar and Storage Solar will include 2 Project substations within two approximately 200 -foot by 200- foot footprint. The substations will contain within its perimeter, a gravel pad, power transformer and footings, electrical control house and concrete foundations, as needed. The substations transformer may be sold for re -use or salvage. Components of the substation that cannot be salvaged will be transported off -site for disposal at an approved solid waste landfill. Although there is some potential that the Project substation may remain at the end of the Project life, an estimated decommissioning cost has been included in this Plan. 2.8 PERIMETER FENCING AND ACCESS ROADS The Project will include a security fence around the perimeter of the site and exclusionary area. The fence will total approximately 93,700 feet in length. Access drives will provide direct access to the solar facility from local roads and along the inner perimeter of the arrays. Internal roads will be located within the array to allow access to the equipment. The site access drives will be approximately 16 feet in width and total approximately 72,800 feet in length. The road widths may change subject to the final design and may utilize geotextile fabric in the road construction. The access road lengths may also change with final Project design. To be conservative, the decommissioning estimate assumes that all access roads will be completely removed. 6 During installation of the Project access roads, the existing topsoil will be excavated to a depth of approximately 6 inches, the subgrade will be compacted, and then 6 inches of granular fill will be placed. The estimated quantity of these materials is provided in Table 2-2, Typical Access Road Construction Materials. TABLE 2-2 TYPICAL ACCESS ROAD CONSTRUCTION MATERIALS Item Quantity Unit Replacement 5,745 Cubic Yards Topsoil Compacted Granular Fill, 8 -inch thick — to be removed 7,800 Cubic Yards Decommissioning activities include the removal and stockpiling of aggregate materials onsite for salvage preparation. It is conservatively assumed that all aggregate materials will be removed from the Project site and hauled up to five miles from the Project area. Following removal of aggregate, the access road areas will be graded, de -compacted with deep ripper or chisel plow (ripped to 18 inches), back -filled with native subsoil and topsoil, as needed, and graded as necessary. 3.0 LAND USE AND ENVIRONMENT 3.1 SOILS AND AGRICULTURAL LAND Areas of the Project that were previously utilized for agricultural purposes will be restored to their pre -construction condition and land use as dictated by the landowner lease agreements. Restored areas will be revegetated in consultation with the current landowner and in compliance with regulations in place at the time of decommissioning. Land disturbed by Project facilities will be restored in such a way to be used in a reasonably similar manner to its original intended use as it existed prior to Project construction. 3.2 RESTORATION AND REVEGETATION Project sites that have been excavated and backfilled will be graded as previously described. Soils compacted during de -construction activities will be de -compacted, as necessary, to restore the land to pre -construction land use. If present, drain tiles that have been damaged will be restored to pre -construction condition. Topsoil will be placed on 7 disturbed areas and seeded with appropriate vegetation or in coordination with landowners within agricultural land. Work will be completed to comply with the conditions agreed upon by Weld County at the time of decommissioning. 3.3 SURFACE WATER DRAINAGE AND CONTROL The proposed Project area is predominantly located in agricultural land. The Project facilities are being sited to avoid wetlands, waterways, and drainage ditches. The existing Project site conditions and proposed BMPs to protect surface water features will be detailed in a Project Stormwater Pollution Prevention Plan (SWPPP) for the Project prior to the commencement of construction activities. Surface water conditions at the Project site will be reassessed prior to the decommissioning phase. Prospect and Janus Solar Solar will obtain the required water quality permits, if needed, before decommissioning of the Project. Construction stormwater permits will also be obtained and a SWPPP prepared describing the protection needed to reflect conditions present at the time of decommissioning. BMPs may include construction entrances, temporary seeding, permanent seeding, mulching (in non-agricultural areas), erosion control matting, silt fence, filter berms, hay bales, and filter socks. 3.4 MAJOR EQUIPMENT REQUIRED FOR DECOMMISSIONING The activities involved in decommissioning the Project include removal of the above ground components of the Project and restoration as described in Section 2.0, Project Components and Decommissioning Activities, and Section 3.2, Restoration and Revegetation. Equipment required for the decommissioning activities is similar to what is needed to construct the solar facility and may include, but is not limited to: small cranes, low ground pressure (LGP) track mounted excavators, backhoes, LGP track bulldozers, LGP off -road end -dump trucks, front-end loaders, deep rippers, water trucks, disc plows and tractors to restore subgrade conditions, and ancillary equipment. Over -the -road dump trucks will be required to transport material removed from the site to disposal facilities. 8 3.5 REMEDIATION OF ENVIRONMENTAL HAZARDS If any environmental hazards are present at the time of decommissioning, including soil or groundwater contamination resulting from site activities, remediation will be conducted to restore site resources to their previous condition prior to project commencement. Environmental remediation will be deemed complete upon receipt of a no further action letter from LDEQ. 4.0 DECOMMISSIONING COST ESTIMATE SUMMARY Expenses associated with decommissioning the Project will be dependent on labor costs at the time of decommissioning. For the purposes of this report, approximate 2021-2022 average market values were used to estimate labor expenses. Fluctuation and inflation of the labor costs were not factored into the estimates. 4.1 DECOMMISSIONING EXPENSES Project decommissioning will incur costs associated with disposal of components not sold for salvage, including materials that will be disposed of at a licensed solid waste landfill, as required.

Modules and other components may be sold within a secondary market or as salvage. The market value of steel and other materials fluctuates daily and has varied widely over the past five years. Salvage value estimates were based on an approximate spot price of steel and copper derived from sources including on-line recycling companies and United States Geological Survey (USGS) commodity summaries. The price used to value the steel used in this report is $295 per metric ton; aluminum at $0.43 per pound; silicon at $0.43 per pound and glass at $0.10 per pound. The main component of the tracking system and piles is assumed to be salvageable steel. Solar panels are estimated to contain approximately 75 percent glass, 8 percent aluminum, and 5 percent silicon. A 70 percent recovery rate was assumed for aluminum and all panel components, due to the processing required to separate the panel components. Alternative and more efficient methods of recycling solar panels are anticipated before this Project is decommissioned, given the large number of solar facilities that are currently being developed. Table 4-2, Estimated Decommissioning Revenues, summarizes the potential salvage value for the solar array components and construction materials. 10 TABLE 4-2 ESTIMATED DECOMMISSIONING REVENUES Item Unit Measurement of Quantity Per Unit Salvage g Price .

PROJECT DESCRIPTION & SCOPE OF WORK The proposed developments are the Janus Solar Project, which includes an 80MWac PV Solar Generation facility and 80MWh Battery Energy Storage (BESS) facility, and the Prospect Solar P roject, which includes an 199MWac PV Solar Generation facility and 400MWh Battery Energy Storage (BESS) facility in Weld County, CO. The solar power generating facilities will consist of rows of Photovoltaic Solar Modules, compacted native access roads, associated electrical equipment, and underground utilities. Solar modules will be mounted on piles and elevated above the ground as to preserve the existing underlying soil and allow for revegetation and infiltration. The projects will be surrounded by a perimeter fence. Ground area within the limits of development that is not occupied by access roads or foundations will be seeded to establish permanent vegetation. From the main access road, there will be gravel access roads to the module areas. This drainage narrative is intended to provide Weld County with preliminary information regarding the drainage and land disturbance activities related to the Janus and Prospect Solar projects together referred to as the "Project" hereinafter. The project will be designed, constructed, and maintained in a manner that minimizes storm water related impacts, in accordance with Weld County drainage criteria.

Therefore, detention ponds designed for this site would be sized to store runoff generated by the 1 -hour, 100- year storm and released of the detained water at the historic runoff rate of the 1 -hour, 10- year storm rate. 1.1. Project Location The existing project site is approximately 2,206 acres combined of agricultural and undeveloped, lightly vegetated land. The project is located south of Roggen and east of Hudson within Weld County. The site is bounded to the north by County Road 75 to the east, County Road 2 to the south, parcel 14773420002 to the west and parcel 147724200019 to the north. Horus Solar Projects - Weld County, CO September 2023 Page 3 Kimley >> Horn Section Township Range The site is located within a portion of the east half of the northwest quarter of Section 34, Township 1 North, Range 63 West of the 6th P.M., Weld County, Colorado. Per FEMA flood maps 08123C2200E and 08123C2200E dated 1/20/2016, subject properties are located in a "Not Printed" Zone. The NRCS Report dated 08/16/2023, concludes that onsite soil consists of Weld loam and Nunn loam that classifies as hydrologic soil group C. Ascalon sandy loam, Colby loam, and Haverson loam that classifies as hydraulic soil group B. Vona sandy loam and Ellicott-Glenberg that classify as soil group A. The site was modeled using type C soils for conservative runoff calculations. All areas that contain panels were modeled using 2% imperviousness for Soils A and B, and 25% imperviousness for Soil group C. For additional detail, refer to Exhibit 2 for the NRCS Report. 1.2. Nearby Water Features & Ownership In the existing condition, a majority of the project site drains to the north, outfalling into Sand Creek, which runs through the center of the project site and flows north. Sand Creek is the receiving waters of the project site and runoff is conveyed to Lost Creek and ultimately end up in the Empire Reservoir. The existing drainage patterns will be maintained in the proposed condition. Refer to Exhibit 4 and Exhibit 5 for the Pre- and Post -Development Drainage Area Maps. 1.3. Report & Analysis Methodologies This report evaluates the pre and post development hydrologic characteristics of the project site (including solar facility footprint and access drive) and addresses the stormwater requirements of Weld County and the state of Colorado. Hydrologic Design Criteria The table below notes the hydrologic design criteria used in the analysis. Parameter Value Unit Reference Time of Concentration, Tc - min. Exhibit 6 Runoff Coefficient, C - - Weld Manual, County Chapter Engineering 5, Tables and 5-3 through Construction 5-5 Criteria 1 -hr Point Rainfall, P1 (100 -Year) 2.66 Inches NOAA Rainfall Data (Exhibit 3) Storm Runoff, Q - cfs Q = CIA Basin Conditions The drainage areas of the site are shown for the site as Pre -construction (Exhibit 4) and Post - construction (Exhibit 5). Pre -construction drainage basins were analyzed to calculate the peak existing runoff for the design storm. Post -construction drainage basins were analyzed to calculate the peak runoff for the design storm in the proposed site conditions. The Weld County Construction and Design Criteria requires areas of proposed solar arrays over a Type C soil classification to utilize an Horus Solar Projects - Weld County, CO September 2023 Page 4 Kimley >> Horn imperviousness of 25%. The total imperviousness for the proposed site was calculated to be 7.6% (see Exhibit 6 for the imperviousness summary). The area under the solar panels will be planted with a low -maintenance grass seed mix, in order to mimic natural processes to manage stormwater, which follows the Low -Impact Development (LID) approach. The existing site land -coverage is agricultural row crops most similar to tillage/agricultural land classification, which does not exhibit the characteristics of a low -impact development. By utilizing the native grass seed mix below the panels, the existing tillage/agricultural land areas will be changed to a heavy meadow land classification that reduces peak flow rates and manages stormwater in line with the historic conditions of the site. The site design promotes conservation design at both the watershed and site levels, with the goal of replicating the native hydrologic characteristics of the sub -watersheds, creating natural ground coverage, and minimizing proposed grading and compaction. The offsite drainage patterns will remain the same as historic conditions. Stormwater Runoff The stormwater runoff for the existing and proposed conditions is calculated utilizing the Rational Method. The 100 -year, 1 -hour storm event was analyzed for pre- and post -construction drainage basins. The flow path for the basins can be seen in Exhibits 4 & 5. The time of concentration to the point of accumulation was calculated using MHFD equations and can be found in Exhibit 6. The basin runoff flowrates were calculated using Weld County UDFCD spreadsheet and can be found in Exhibit 7. The Runoff Coefficients are also included in Exhibit 6. The precipitation data used for the 100 -year; 1 -hour storm event is based on NOAA rainfall data from the project site (Exhibit 3). A summary of the rational calculation findings is shown in the table below. Existing Proposed Area 2171.3 ac 2171.3 ac Imperviousness 2.0 % 7.6 % Qioo 1398.0 cfs 1001.6 cfs 1.4. Stormwater Management A study published in the Journal of Hydrologic Engineering researched the hydrologic impacts of utility scale solar generating facilities. The study utilized a model to simulate runoff from pre -and post -solar panel conditions. The study concluded that the solar panels themselves have little to no impact on runoff volumes or rates. Rainfall losses, most notably infiltration, are not impacted by the solar panels. Rainfall that falls directly on a solar panel runs to the pervious areas around and under the surrounding panels. Refer to Exhibit 8 for the study published in the Journal of Hydrologic Engineering. Under developed conditions, runoff will follow existing drainage patterns and will reduce peak flows (decreases from 1398.0 cfs to 1001.6 cfs in the 100 -year, l -hour storm event). Detention Ponds Drainage basins 41 and 42 will have extended detention ponds due to the higher imperviousness that is proposed within these basins. The remainder of the drainage basins on the project site will reduce runoff flows from the existing to the proposed condition, and therefore do not require Horus Solar Projects - Weld County, CO September 2023 Page 5 Kimley >> Horn stormwater detainment. The required storage volumes will be provided in the proposed detention ponds, and the water quality volume will be released over a 40 -hour period.

CONCLUSION The following list summarizes key components of the Project and findings related to land disturbance and storm water impacts. • Installation of the solar facility will temporarily disturb portions of the existing topsoil within the 2171.3 -acre Project. The proposed site will be designed to maintain its existing drainage patterns and reduce runoff through the LID approach on the majority of the site, and with detention ponds placed in drainage areas 41 and 42 for runoff from the substations. • The areas considered impervious or semi -impervious are a large portion of the project area, however the semi -impervious areas under the solar panels (modeled as 25% impervious) represent 25% of the total site area, and by implementing low -maintenance grass seed mix underneath, the site will reduce peak flow rates from existing conditions. • Under existing conditions, the peak flow from the site area for the 100 yr - lhr storm event is 1398.0 cfs. • Under developed conditions, the peak flow from the site area for the 100 yr — 1 hr storm event is 1001.6 cfs. • Installation of the solar facility will not increase existing or flow rates on or around the project site. Runoff water quality will not be impacted by the solar facility components. • The project design will adequately protect public health, safety and general welfare and have no adverse effects on Weld County right-of-way or offsite properties. • The proposed site will be designed to maintain its existing drainage patterns across the solar site. As noted above, a study published in the Journal of Hydrologic Engineering (Exhibit 8) researched the hydrologic impacts of utility scale solar generating facilities. The study utilized a model to simulate runoff from pre -development and post -development solar panel conditions. The study concluded that the solar panels themselves have little to no impact on runoff volumes or rates. Rainfall losses, most notably infiltration, are not impacted by the solar panels. Rainfall that falls directly on a solar panel runs to the pervious areas around and under the surrounding panels. Horus Solar Projects - Weld County, CO September 2023 Page 6 Kimley >> Horn Grading is proposed with minimal changes to the existing site drainage patterns and onsite access roads will be compacted gravel. Based on the proposed improvements on the project site, the findings of the above referenced study, and the calculations included within this report, the site will reduce peak flows from the existing rates. Therefore, permanent stormwater detention is only being provided for the proposed substations on the project, and the proposed areas of PV arrays will not include stormwater detention or water quality measures. We trust that the information provided is acceptable and complete for preliminary site plan review drainage report requirements. Please let us know if you have any questions or need additional information. KIMLEY-HORN LEY -HORN AND ASSOCIATES, INC.

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

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

Abstract: Because of the benefits of solar energy, the number of solar farms is increasing; however, their hydrologic impacts have not been studied. The goal of this study was to determine the hydrologic effects of solar farms and examine whether or not storm -water management is needed to control runoff volumes and rates. A model of a solar farm was used to simulate runoff for two conditions: the pre- and postpaneled conditions. Using sensitivity analyses, modeling showed that the solar panels themselves did not have a significant effect on the runoff volumes, peaks, or times to peak. However, if the ground cover under the panels is gravel or bare ground, owing to design decisions or lack of maintenance, the peak discharge may increase significantly with storm -water management needed. In addition, the kinetic energy of the flow that drains from the panels was found to be greater than that of the rainfall, which could cause erosion at the base of the panels. Thus, it is recommended that the grass beneath the panels be well maintained or that a buffer strip be placed after the most downgradient row of panels. This study, along with design recommendations, can be used as a guide for the future design of solar fauns. DOI: 10.1061/(ASCE) HE.1943-5584.0000530. © 2013 American Society of Civil Engineers.

Introduction Storm -water management practices are generally implemented to reverse the effects of land -cover changes that cause increases in volumes and rates of runoff. This is a concern posed for new types of land -cover change such as the solar farm. Solar energy is a re- newable energy source that is expected to increase in importance in the near future. Because solar farms require considerable land, it is necessary to understand the design of solar farms and their potential effect on erosion rates and storm runoff, especially the impact on offsite properties and receiving streams. These farms can vary in size from 8 ha (20 acres) in residential areas to 250 ha (600 acres) in areas where land is abundant. The solar panels are impervious to rain water; however, they are mounted on metal rods and placed over pervious land. In some cases, the area below the panel is paved or covered with gravel. Service roads are generally located between rows of panels. Altl- hough some panels are stationary, others are designed to move so that the angle of the panel varies with the angle of the sun. The angle can range, depending on the latitude, from 22° during the summer months to 74° during the winter months. In addition, the angle and direction can also change throughout the day. The issue posed is whether or not these rows of impervious panels will change the runoff characteristics of the site, specifically increase runoff volumes or peak discharge rates. If the increases are hydro- logically significant, storm -water management facilities may be needed. Additionally, it is possible that the velocity of water 1Research Assistant, Dept. of Civil and Environmental Engineering, Univ. of Maryland, College Park, MD 20742-3021. 2The Ben Dyer Professor, Dept. of Civil and Environmental Engineer- ing, Univ. of Maryland, College Park, MD 20742-3021 (corresponding author).

The outcome of this study provides guidance for assessing the hydrologic effects of solar farms, which is important to those who plan, design, and install arrays of solar panels. Those who design solar farms may need to provide for storm -water management. This study investigated the hydrologic effects of solar farms, assessed whether or not storm -water management might be needed, and if the velocity of the runoff from the panels could be sufficient to cause erosion of the soil below the panels. Model Development Solar farms are generally designed to maximize the amount of en- ergy produced per unit of land area, while still allowing space for maintenance. The hydrologic response of solar farms is not usually considered in design. Typically, the panels will be arrayed in long rows with separations between the rows to allow for maintenance vehicles. To model a typical layout, a unit width of one panel was assumed, with the length of the downgradient strip depending on the size of the farm. For example, a solar farm with 30 rows of 200 panels each could be modeled as a strip of 30 panels with space between the panels for maintenance vehicles. Rainwater that drains from the upper panel onto the ground will flow over the land under the 29 panels on the downgradient strip. Depending on the land cover, infiltration losses would be expected as the runoff flows to the bottom of the slope. To determine the effects that the solar panels have on runoff characteristics, a model of a solar farm was developed. Runoff in the form of sheet flow without the addition of the solar panels served as the prepaneled condition. The paneled condition assumed a downgradient series of cells with one solar panel per ground cell. Each cell was separated into three sections: wet, dry, and spacer. The dry section is that portion directly underneath the solar panel, unexposed directly to the rainfall. As the angle of the panel from the horizontal increases, more of the rain will fall directly onto 536 / JOURNAL OF HYDROLOGIC ENGINEERING © ASCE / MAY 2013 J. Hydrol. Eng. 2013.18:536-541.

The spacer section is the area between the rows of panels used by maintenance vehicles. Fig. 1 is an image of two solar panels and the spacer section allotted for maintenance vehicles. Fig. 2 is a sche- matic of the wet, dry, and spacer sections with their respective di- mensions. In Fig. 1, tracks from the vehicles are visible on what is modeled within as the spacer section. When the solar panel is hori- zontal, then the length longitudinal to the direction that runoff will occur is the length of the dry and wet sections combined. Runoff from a dry section drains onto the downgradient spacer section. Runoff from the spacer section flows to the wet section of the next downgradient cell. Water that drains from a solar panel falls directly onto the spacer section of that cell. The length of the spacer section is constant. During a storm event, the loss rate was assumed constant for the 24-h storm be- cause a wet antecedent condition was assumed. The lengths of the wet and dry sections changed depending on the angle of the solar panel. The total length of the wet and dry sections was set Fig. 1.

Wet, dry, and spacer sections of a single cell with lengths Lw, Ls, and Ld with the solar panel covering the dry section equal to the length of one horizontal solar panel, which was as- sumed to be 3.5 m. When a solar panel is horizontal, the dry section length would equal 3.5 m and the wet section length would be zero. In the paneled condition, the dry section does not receive direct rainfall because the rain first falls onto the solar panel then drains onto the spacer section. However, the dry section does infiltrate some of the runoff that comes from the upgradient wet section. The wet section was modeled similar to the spacer section with rain falling directly onto the section and assuming a constant loss rate. For the presolar panel condition, the spacer and wet sections are modeled the same as in the paneled condition; however, the cell does not include a dry section. In the prepaneled condition, rain falls directly onto the entire cell. When modeling the prepaneled condition, all cells receive rainfall at the same rate and are subject to losses. All other conditions were assumed to remain the same such that the prepaneled and paneled conditions can be compared. Rainfall was modeled after an natural resources conservation service (NRCS) Type II Storm (McCuen 2005) because it is an ac- curate representation of actual storms of varying characteristics that are imbedded in intensity -duration -frequency (IDF) curves. For each duration of interest, a dimensionless hyetograph was devel- oped using a time increment of 12 s over the duration of the storm (see Fig. 3). The depth of rainfall that corresponds to each storm magnitude was then multiplied by the dimensionless hyetograph. For a 2-h storm duration, depths of 40.6, 76.2, and 101.6 mm were used for the 2-, 25-, and 100 -year events. The 2- and 6-h duration hyetographs were developed using the center portion of the 24-h storm, with the rainfall depths established with the Baltimore IDF curve. The corresponding depths for a 6-h duration were 53.3, 106.7, and 132.1 mm, respectively. These magnitudes were chosen to give a range of storm conditions. During each time increment, the depth of rain is multiplied by the cell area to determine the volume of rain added to each section of each cell. This volume becomes the storage in each cell. Depend- ing on the soil group, a constant volume of losses was subtracted from the storage. The runoff velocity from a solar panel was calcu- lated using Manning's equation, with the hydraulic radius for sheet flow assumed to equal the depth of the storage on the panel (Bedient and Huber 2002). Similar assumptions were made to com- pute the velocities in each section of the surface sections. 20 40 60 Time (min) 80 100 120 Fig. 3.

Runoff from one section to the next and then to the next downgradient cell was routed using the continuity of mass. The routing coefficient depended on the depth of flow in storage and the velocity of runoff. Flow was routed from the wet section to the dry section to the spacer section, with flow from the spacer section draining to the wet section of the next cell. Flow from the most downgradient cell was assumed to be the outflow. Discharge rates and volumes from the most downgradient cell were used for com- parisons between the prepaneled and paneled conditions. Alternative Model Scenarios To assess the effects of the different variables, a section of 30 cells, each with a solar panel, was assumed for the base model. Each cell was separated individually into wet, dry, and spacer sections. The area had a total ground length of 225 m with a ground slope of 1% and width of 5 m, which was the width of an average solar panel. The roughness coefficient (Engman 1986) for the silicon solar panel was assumed to be that of glass, 0.01. Roughness coefficients of 0.15 for grass and 0.02 for bare ground were also assumed. Loss rates of 0.5715 cm/h (0.225 in./h) and 0.254 cm/h (0.1 in./h) for B and C soils, respectively, were assumed. The prepaneled condition using the 2-h, 25 -year rainfall was assumed for the base condition, with each cell assumed to have a good grass cover condition. All other analyses were made assum- ing a paneled condition. For most scenarios, the runoff volumes and peak discharge rates from the paneled model were not significantly greater than those for the prepaneled condition. Over a total length of 225 m with 30 solar panels, the runoff increased by 0.26 m3, which was a difference of only 0.35%. The slight increase in runoff volume reflects the slightly higher velocities for the paneled con- dition. The peak discharge increased by 0.0013 m3, a change of only 0.31%. The time to peak was delayed by one time increment, i.e., 12 s. Inclusion of the panels did not have a significant hydro- logic impact. Storm Magnitude The effect of storm magnitude was investigated by changing the magnitude from a 25 -year storm to a 2 -year storm. For the 2 -year storm, the rainfall and runoff volumes decreased by approximately 50%. However, the runoff from the paneled watershed condition increased compared to the prepaneled condition by approximately the same volume as for the 25 -year analysis, 0.26 m3. This increase represents only a 0.78% increase in volume. The peak discharge and the time to peak did not change significantly. These results re- flect runoff from a good grass cover condition and indicated that the general conclusion of very minimal impacts was the same for dif- ferent storm magnitudes. Ground Slope The effect of the downgradient ground slope of the solar farm was also examined. The angle of the solar panels would influence the velocity of flows from the panels. As the ground slope was in- creased, the velocity of flow over the ground surface would be closer to that on the panels. This could cause an overall increase in discharge rates. The ground slope was changed from 1 to 5%, with all other conditions remaining the same as the base conditions. With the steeper incline, the volume of losses decreased from that for the 1% slope, which is to be expected because the faster velocity of the runoff would provide less opportunity for infiltra- tion. However, between the prepaneled and paneled conditions, the increase in runoff volume was less than 1%. The peak discharge and the time to peak did not change. Therefore, the greater ground slope did not significantly influence the response of the solar farm. Soil Type The effect of soil type on the runoff was also examined. The soil group was changed from B soil to C soil by varying the loss rate. As expected, owing to the higher loss rate for the C soil, the depths of runoff increased by approximately 7.5% with the C soil when com- pared with the volume for B soils. However, the runoff volume for the C soil condition only increased by 0.17% from the prepaneled condition to the paneled condition. In comparison with the B soil, a difference of 0.35% in volume resulted between the two conditions. Therefore, the soil group influenced the actual volumes and rates, but not the relative effect of the paneled condition when compared to the prepaneled condition. Panel Angle Because runoff velocities increase with slope, the effect of the angle of the solar panel on the hydrologic response was examined. Analy- ses were made for angles of 30° and 70° to test an average range from winter to summer. The hydrologic response for these angles was compared to that of the base condition angle of 45°. The other site conditions remained the same. The analyses showed that the angle of the panel had only a slight effect on runoff volumes and discharge rates. The lower angle of 30° was associated with an in- creased runoff volume, whereas the runoff volume decreased for the steeper angle of 70° when compared with the base condition of 45°. However, the differences (~0.5%) were very slight. Never- theless, these results indicate that, when the solar panel was closer to horizontal, i.e., at a lower angle, a larger difference in runoff volume occurred between the prepaneled and paneled conditions. These differences in the response result are from differences in loss rates. The peak discharge was also lower at the lower angle. At an angle of 30°, the peak discharge was slightly lower than at the higher angle of 70°. For the 2-h storm duration, the time to peak of the 30° angle was 2 min delayed from the time to peak of when the panel was positioned at a 70° angle, which reflects the longer travel times across the solar panels. Storm Duration To assess the effect of storm duration, analyses were made for 6-h storms, testing magnitudes for 2-, 25-, and 100 -year return periods, with the results compared with those for the 2-h rainfall events. The longer storm duration was tested to determine whether a longer du- ration storm would produce a different ratio of increase in runoff between the prepaneled and paneled conditions. When compared to runoff volumes from the 2-h storm, those for the 6-h storm were 34% greater in both the paneled and prepaneled cases. However, when comparing the prepaneled to the paneled condition, the in- crease in the runoff volume with the 6-h storm was less than 1% regardless of the return period. The peak discharge and the time -to -peak did not differ significantly between the two condi- tions. The trends in the hydrologic response of the solar farm did not vary with storm duration. Ground Cover The ground cover under the panels was assumed to be a native grass that received little maintenance. For some solar farms, the area be- neath the panel is covered in gravel or partially paved because the panels prevent the grass from receiving sunlight.

Thus, it was necessary to determine whether or not these alternative ground -cover conditions would affect the runoff characteristics. This was accomplished by changing the Manning's n for the ground beneath the panels. The value of n under the pan- els, i.e., the dry section, was set to 0.015 for gravel, with the value for the spacer or maintenance section set to 0.02, i.e., bare ground. These can be compared to the base condition of a native grass (n = 0.15). A good cover should promote losses and delay the runoff. For the smoother surfaces, the velocity of the runoff increased and the losses decreased, which resulted in increasing runoff vol- umes. This occurred both when the ground cover under the panels was changed to gravel and when the cover in the spacer section was changed to bare ground. Owing to the higher velocities of the flow, runoff rates from the cells increased significantly such that it was necessary to reduce the computational time increment. Fig. 4(a) shows the hydrograph from a 30 -panel area with a time incre- ment of 12 s. With a time increment of 12 s, the water in each cell is discharged at the end of every time increment, which results in no attenuation of the flow; thus, the undulations shown in Fig. 4(a) result. The time increment was reduced to 3 s for the 2-h storm, which resulted in watershed smoothing and a rational hydrograph shape [Fig. 4(b)] . The results showed that the storm runoff 0.1 0.09 0.08 0.07 0.06 P. 0.05 0 0.04 0.03 (a) 0.02 0.01 0 0.07 0.06 20 40 60 80 100 120 140 160 180 Time (min) 0.05 - el; 0.04\- a) co -50.03 0.02 I- 0.01 - (b) Paneled Pre -paneled 20 40 60 80 100 120 140 160 180 200 Time (min) Fig. 4. Hydrograph with time increment of (a) 12 s; (b) 3 s with Manning's n for bare ground increased by 7% from the grass -covered scenario to the scenario with gravel under the panel. The peak discharge increased by 73% for the gravel ground cover when compared with the grass cover without the panels. The time to peak was 10 min less with the gravel than with the grass, which reflects the effect of differ- ences in surface roughness and the resulting velocities. If maintenance vehicles used the spacer section regularly and the grass cover was not adequately maintained, the soil in the spacer section would be compacted and potentially the runoff volumes and rates would increase. Grass that is not maintained has the potential to become patchy and turn to bare ground. The grass under the panel may not get enough sunlight and die. Fig. 1 shows the result of the maintenance trucks frequently driving in the spacer section, which diminished the grass cover. The effect of the lack of solar farm maintenance on runoff char- acteristics was modeled by changing the Manning's n to a value of 0.02 for bare ground. In this scenario, the roughness coefficient for the ground under the panels, i.e., the dry section, as well as in the spacer cell was changed from grass covered to bare ground (n = 0.02).The effects were nearly identical to that of the gravel. The runoff volume increased by 7% from the grass -covered to the bare -ground condition. The peak discharge increased by 72% when compared with the grass -covered condition. The runoff for the bare - ground condition also resulted in an earlier time to peak by approx- imately 10 min. Two other conditions were also modeled, showing similar results. In the first scenario, gravel was placed directly under the panel, and healthy grass was placed in the spacer section, which mimics a possible design decision. Under these conditions, the peak discharge increased by 42%, and the volume of runoff increased by 4%, which suggests that storm -water management would be necessary if gravel is placed anywhere. Fig. 5 shows two solar panels from a solar farm in New Jersey. The bare ground between the panels can cause increased runoff rates and reductions in time of concentration, both of which could necessitate storm -water management. The final condition modeled involved the assumption of healthy grass beneath the panels and bare ground in the spacer section, which would simulate the con- dition of unmaintained grass resulting from vehicles that drive over the spacer section. Because the spacer section is 53% of the cell, the change in land cover to bare ground would reduce losses and de- crease runoff travel times, which would cause runoff to amass as it Fig. 5.

With the spacer section as bare ground, the peak discharge increased by 100%, which reflected the increases in volume and decrease in timing. These results illustrate the need for maintenance of the grass below and between the panels. Design Suggestions With well -maintained grass underneath the panels, the solar panels themselves do not have much effect on total volumes of the runoff or peak discharge rates. Although the panels are impervious, the rainwater that drains from the panels appears as runoff over the downgradient cells. Some of the runoff infiltrates. If the grass cover of a solar farm is not maintained, it can deteriorate either because of a lack of sunlight or maintenance vehicle traffic. In this case, the runoff characteristics can change significantly with both runoff rates and volumes increasing by significant amounts. In addition, if gravel or pavement is placed underneath the panels, this can also contribute to a significant increase in the hydrologic response. If bare ground is foreseen to be a problem or gravel is to be placed under the panels to prevent erosion, it is necessary to counteract the excess runoff using some form of storm -water man- agement. A simple practice that can be implemented is a buffer strip (Dabney et al. 2006) at the downgradient end of the solar farm. The buffer strip length must be sufficient to return the runoff character- istics with the panels to those of runoff experienced before the gravel and panels were installed. Alternatively, a detention basin can be installed. A buffer strip was modeled along with the panels. For approxi- mately every 200 m of panels, or 29 cells, the buffer must be 5 cells long (or 35 m) to reduce the runoff volume to that which occurred before the panels were added. Even if a gravel base is not placed under the panels, the inclusion of a buffer strip may be a good prac- tice when grass maintenance is not a top funding priority. Fig. 6 shows the peak discharge from the graveled surface versus the length of the buffer needed to keep the discharge to prepaneled peak rate. Water draining from a solar panel can increase the potential for erosion of the spacer section. If the spacer section is bare ground, the high kinetic energy of water draining from the panel can cause soil detachment and transport (Garde and Raju 1977; Beuselinck et al. 2002). The amount and risk of erosion was modeled using the velocity of water coming off a solar panel compared with the velocity and intensity of the rainwater.

Peak discharge over gravel compared with buffer length 40 runoff was calculated using Manning's equation, and the velocity of falling rainwater was calculated using the following: Vt = 124.35 (1) where d,. = diameter of a raindrop, assumed to be 1 mm. The re- lationship between kinetic energy and rainfall intensity is Ke = 916 + 330 1og10i (2) where i = rainfall intensity (in./h) and Ke = kinetic energy (ft -tons per ac -in. of rain) of rain falling onto the wet section and the panel, as well as the water flowing off of the end of the panel (Wischmeier and Smith 1978). The kinetic energy (Salles et al. 2002) of the rain- fall was greater than that coming off the panel, but the area under the panel (i.e., the product of the length, width, and cosine of the panel angle) is greater than the area under the edge of the panel where the water drains from the panel onto the ground. Thus, dividing the kinetic energy by the respective areas gives a more accurate representation of the kinetic energy experienced by the soil. The energy of the water draining from the panel onto the ground can be nearly 10 times greater than the rain itself falling onto the ground area. If the solar panel runoff falls onto an un- sealed soil, considerable detachment can result (Motha et al. 2004). Thus, because of the increased kinetic energy, it is pos- sible that the soil is much more prone to erosion with the panels than without. Where panels are installed, methods of erosion control should be included in the design. Conclusions Solar farms are the energy generators of the future; thus, it is im- portant to determine the environmental and hydrologic effects of these farms, both existing and proposed. A model was created to simulate storm -water runoff over a land surface without panels and then with solar panels added. Various sensitivity analyses were conducted including changing the storm duration and volume, soil type, ground slope, panel angle, and ground cover to determine the effect that each of these factors would have on the volumes and peak discharge rates of the runoff. The addition of solar panels over a grassy field does not have much of an effect on the volume of runoff, the peak discharge, nor the time to peak. With each analysis, the runoff volume increased slightly but not enough to require storm -water management facili- ties. However, when the land -cover type was changed under the panels, the hydrologic response changed significantly. When gravel or pavement was placed under the panels, with the spacer section left as patchy grass or bare ground, the volume of the runoff in- creased significantly and the peak discharge increased by approx- imately 100%. This was also the result when the entire cell was assumed to be bare ground. The potential for erosion of the soil at the base of the solar pan- els was also studied. It was determined that the kinetic energy of the water draining from the solar panel could be as much as 10 times greater than that of rainfall. Thus, because the energy of the water draining from the panels is much higher, it is very possible that soil below the base of the solar panel could erode owing to the concen- trated flow of water off the panel, especially if there is bare ground in the spacer section of the cell. If necessary, erosion control meth- ods should be used. Bare ground beneath the panels and in the spacer section is a realistic possibility (see Figs. 1 and 5). Thus, a good, well - maintained grass cover beneath the panels and in the spacer section is highly recommended. If gravel, pavement, or bare ground is 540 / JOURNAL OF HYDROLOGIC ENGINEERING © ASCE / MAY 2013 J. Hydrol. Eng. 2013.18:536-541.

If these simple measures are taken, solar farms will not have an adverse hydrologic impact from excess runoff or contribute eroded soil particles to receiving streams and waterways.

Site maintenance is critical to ensure that an operational solar facility meets all conditions of operation. This document outlines the steps the operator will take to ensure the site is properly maintained during construction and throughout the operational life of the facility. 1. Dust Management During the Construction Phase Dust palliatives, suppressant, or binders and water tankers will be used to help control dust while the construction activities are occurring on the site. During the construction of the facility, BMPs will be utilized to limit fugitive dust from being airborne and traveling beyond the property lines. Dust control efforts will be monitored by the site foreman on a regular basis to ensure fugitive dust is adequately controlled. Dust palliatives, suppressants, or binders are to be primarily used to stabilize soil and aggregates to control dust during construction as required in order to limit Water Usage. The main construction activities that require dust control are use of unpaved roads and staging areas as well as clearing, excavation, and grading. Dust palliatives and/or water spray will be applied, as needed, to unpaved areas, temporary haul roads, staging and laydown areas, driveways, and other areas identified in the project specifications. Continuous inspection shall occur during initial application of dust palliatives, suppressant, or binders to verify application equipment and application rates. Verify adequate cure of dust palliatives, suppressant, or binders before opening treated areas to traffic. Dust control chemicals must be applied in such a manner that will not contaminate any waters of the US. Dust control chemicals shall not be applied to areas within 100 feet of a wetland or body of water. Care will be taken not to over -apply and create mud. Vehicle tracking devices will be installed at truck exit drives. Vehicles operating on the site during the construction phase will limit their speed to 5 mph or less, to minimize dust emissions. Operators shall continuously employ the practices listed above for control of fugitive dust. Weed Management The Colorado Department of Agriculture (CDA) requires landowners to prevent the spread of State Listed Noxious Weeds. Construction activities on the site have the potential to introduce new noxious weed species to the site, or spread existing species on to or off of the site. This noxious weed management program was developed to prevent further spread of noxious weeds. Janus Solar will comply with CDA regulations through implementation of this plan. Periodic reviews and updates to this plan will be completed as necessary to keep it current with noxious weed control issues. This plan will be implemented throughout the life of the solar facility. Page 2 of 7 wood Janus Solar— Dust and Weed Mitigation Plan Appropriate management actions will be implemented wherever noxious weed species are observed growing within the project area. The goals of weed management are to: • Identify and manage noxious weeds within, and immediately adjacent to, the project areas to be disturbed and after the area has been reclaimed; • Conduct pre-treatment and post -treatment evaluations, and continue or modify treatment measures as necessary; • Minimize the potential for transportation and importation of noxious weed species; • Educate field personnel in order to encourage compliance with weed management program goals and assist with identification and control efforts. To prevent or minimize the infestation and spread, periodic inspections of the project area during the beginning, middle, and end of the growing season will evaluate presence or absence, degree of invasion, and the response of previous treatments. Janus Solar's operational staff will conduct regular site inspections and ensure implementation of this plan. Specific treatment methodologies and timetables will be developed based on species of concern, location and extent of the infestation(s), and other pertinent factors. 2.1. Noxious Weed Prevention Noxious weeds are spread through dispersal of seed and/or transport of plant propagules (i.e. spores, seeds, roots, etc.). The most effective way to control noxious weeds is to prevent their introduction into the site in the first place. The following methods and practices may be employed, individually or in combination, to prevent the introduction of weed species and their regeneration within the project area: • A thorough cleaning of equipment will be conducted before entering the project area to prevent the introduction of seed and plant propagules from other sites; • Seed mixtures used for revegetation or temporary site stabilization will be free of noxious weeds; • Hay, straw, and/or other materials used for mulch or other purposes will be certified weed free; • A periodic inspection will be conducted to identify any new weed infestations that may have occurred. Any new infestations will be scheduled for management before they become well established and/or spread; • Communication and coordination with adjacent land holders whose property is infested with noxious weeds that may threaten the site should occur. Establishing partnerships for weed management within the local area is essential for successful long-term weed management; • Noxious and pest weed infestations that threaten natural and reclaimed areas will be treated with accepted Integrated Weed Management (IWM) methods. These methods are further discussed below. Page 3 of 7 wood Janus Solar— Dust and Weed Mitigation Plan 2.2. Integrated Weed Management An Integrated Weed Management (IWM) approach will be implemented for treatment of noxious weeds within the project area. An IWM approach enables selection of one or more weed management methods based on site specific environmental conditions and control needs. The following weed management methods will be considered for the project area: 1.) Cultural — Planting native or desirable plant species for site colonization and promoting healthy vegetation communities in reclaimed areas. Preventing unnecessary ground disturbance through precise planning of construction projects and other activities. Managing the prompt revegetation of disturbed areas. 2.) Mechanical — Mowing, pulling, disking, and plowing may be used on weedy species for which these treatments are effective. 3.) Biological — Introduction of insects or other biologic agents which are known to inhibit or prevent reproduction of noxious weed species. If biological agents are employed, control methods will be coordinated with the Colorado Department of Agricultural Insectary in Palisade, Colorado. 4.) Chemical — Application of appropriate herbicides by a licensed applicator. All herbicides will be applied in accordance with the manufacturer's label and in accordance with Colorado laws. Mechanical w Chemical IWM Biological Prevention In some cases, only one control method may be warranted, while in other cases a combination of control methods may be appropriate. Control methods selected will be dependent upon species of concern, and the location and extent of the infestation. The use of IWM methods will protect pollinators, reduce hazards to wildlife, reduce the possibility of herbicide resistance, and minimize persistence and mobility of herbicides in the soil. Weed control methods and practices will be applied in a manner that conforms to applicable federal, state, and local laws. Page 4 of 7 wood Janus Solar— Dust and Weed Mitigation Plan 2.2.1. Cultural Control Germination and establishment of noxious weeds can be reduced by following accepted revegetation and vegetation management techniques that favor the growth of desirable plants. These include prompt seeding and revegetation of disturbed areas with appropriate seed mixes, maintaining optimum fertility and moisture levels, planting at optimum density of pure live seed, minimizing use of fertilizers, and selecting suitable species for revegetation. Minimizing areas of disturbance and exposed soil prevents opportunities for aggressive species to establish. A site specific revegetation plan will be developed for the site that utilizes native species that are well - adapted to the site. Seeding native species in conjunction with other management practices will provide some level of competition with noxious weeds and minimize the opportunity for new infestations to become established. 2.2.2. Mechanical Control Mechanical Control of noxious weeds can be an effective tool to physically disrupt noxious weed growth and seed development. A combination of mechanical methods may be used including tilling or disking, mowing, hand-held weed trimmers, mulching, hand -pulling, hoeing, or livestock grazing. Mechanical weed control practices must be applied with correct timing to maximize their effectiveness in preventing vegetation development or seed production. Annual weedy species may be readily controlled with mowing or physical removal. Perennial species such as Dalmatian toadflax have extensive root systems. For such weed species, mowing may only control seed production without seriously affecting the plant's survival. Mowing after seed production has occurred may spread the plants. Disking or tilling areas containing perennial noxious species may increase the area of infestation due to root sprouting. In most cases, mechanical control methods used alone are not effective against noxious weed species. 2.2.3. Biological Control Biological control of noxious weeds can be an effective tool to physically disrupt plant growth and seed development. A combination of biological methods may be used including introduction of insect weed predators and species -specific plant diseases. Biological weed control methods and practices will be applied with appropriate timing to maximize their effectiveness in preventing seed production. It must be noted that the use of biological controls normally does not eradicate an infestation of weeds; rather they are capable of reducing weed species vigor and reproduction. The CDA's Biological Pest Control Program has on -going biological control programs for several noxious weed species. Note, the use of insect bio-controls typically require large populations of the target weed to sustain the population of bio-control agents. Biological controls should not be expected to eliminate the entire infestation of a noxious weed, but instead to bring the infestation down to a more manageable level. Page 5 of 7 wood Janus Solar— Dust and Weed Mitigation Plan 2.2.4. Chemical Control Chemical control of noxious and pest weeds can be an effective tool to disrupt plant growth and seed development. Herbicides can kill targeted species, prevent development and/or germination of noxious weed seed, can be used with minimal disturbance to soils, and in some cases, can be selective to specific species or groups of plants. Herbicides must be applied at the appropriate time to maximize their effectiveness in preventing seed production, for disrupting plant establishment and growth, or achieving kill of noxious species. To avoid development of resistance to a particular herbicide through repeated use over prolonged periods of time, herbicides with varying modes of action are to be used. Also, herbicides will be applied according to manufacturer's label recommendations (i.e. application rate, method, and timing) to prevent development of plant resistance. Herbicide selection will be based on weed emergence, timing of application, past applications, and ground and weather conditions during the applications. Successful IWM begins with an understanding of the target plant species and the environment within which it grows. Next, the physiologic effects of an herbicide on plant growth and development must be understood. Understanding a pesticide's chemical nature is also important in minimizing impacts to non - target species, the applicator, endangered species, and pollinators, as well as surface water runoff hazards and leaching into groundwater. Every herbicide label contains information regarding environmental hazards. This information will be evaluated for each herbicide considered for use at the site and herbicides will be selected which pose minimal to no environmental hazards. All pesticides will be handled with care and applied by qualified personnel. Properly identifying the weed problem and the most effective chemical control method for use during the plant growth cycle is critical to effective weed control. Equipment will be properly calibrated before herbicides are applied and appropriate Personal Protective Equipment (PPE) will be used. Empty containers will be disposed of promptly, safely, and according with product labeling. Herbicides vary in the amount of time after an application before it is safe to re-enter the treated area without protective clothing and equipment. The site re-entry time is affected by the rate of application, size of the area treated and the amount of time to be spent in the field. For the safety of employees and contractors, the Restricted Entry Interval (REI) listed on the herbicide's label will be followed. Appropriate herbicide application records will be maintained as specified by the CDA. 2.3. Monitoring and Follow -Up Even with effective weed management strategies, it often takes several seasons to eradicate or bring weed populations to an acceptable level. With well -established infestations, it is likely that a seed bank has developed in the soil capable of producing new plants for many years. An infestation of weeds can easily re -invade treated areas in one growing season if control and treatment activities are prematurely curtailed. Page 6of7 wood Janus Solar— Dust and Weed Mitigation Plan Weed management efforts should be carried out over an adequate number of growing seasons to realize effective weed management within the target area. As with all weed management practices, this multi -season effort is best served by effective documentation of control efforts and continued vigilance in successive seasons of management. Information can be used to modify treatment priorities and weed management strategies over time. Vigilance is required against new infestations that may be moving into the site. These new sources of infestation may be worked into prevention and management plans as necessary. This weed management plan will be modified over time as site conditions change. Weed management strategies and priorities can be modified as weed infestations change in response to continued control efforts. 3. Drainage and Erosion Control Installation of the solar facility will not alter existing drainage patterns or flow rates on the site and runoff water quality will not be impacted by the solar facility components. Installation of water quality or detention facilities will be implemented in accordance with the project's drainage report. Appropriate temporary construction -related erosion and sedimentation control Best Management Practices (BMPs), will be applied during the construction phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality.

The optimal resting angle of a tracker panel system can be key to reducing the amount of total predicted glare from the project into the surrounding ground scenarios. The resting angle of a solar system can be defined as the angle of rotation of panels when sun is outside tracking range and backtracking rotation has settled. Resting angles for the tracker panel system were set to 35 degrees as assigned by the owner of the proposed project. At a 35 -degree resting angle no glare is predicted on the OPs and Routes around this proposed project. In the above graphic, Red Markers represent Observation Points and Turquoise Lines are the roads in and around the proposed project area. Keenesburg, CO Glare Study Results October 3, 2023 Update 2 Colliers Engineering & Design The client also requested a review of how glare might or might not affect a landing strip owned by a resident of the area. Per the FAA regulation standards, a 2 -mile flightpath radius was studied. If this was an FAA regulated airport, the proposed solar project would PASS the 2021 Policy. More detail regarding this is included in the Results of this Study Section.

Solar Glare Hazard Analysis Tool (SGHAT) Technical Reference Manual Keenesburg, CO Glare Study Results October 3, 2023 Update 6 Colliers Engineering & Design Details of Glare Study Methodology (Source Information: https://forgesolar.com/help/#intro) Collier's Engineering & Design (CED) offers staff specifically trained on glare analyses utilizing ForgeSolar, a web -based interactive software that provides a quantified assessment of (1) when and where glare is predicted to occur throughout the year for a prescribed solar installation, and (2) potential effects on the human eye at locations where glare is predicted to occur. ForgeSolar is based on the Solar Glare Hazard Analysis Tool ("SGHAT") licensed from Sandia National Laboratories. These tools meet the FAA standards for glare analysis. Determination of glare occurrence requires knowledge of the following: sun position, observer location, and the tilt, orientation, location, extent, and optical properties of the modules in the solar array. Vector algebra is then used to determine if glare is likely to be visible from the prescribed observation points. If glare is predicted, the software calculates the retinal irradiance and subtended angle (size/distance) of the glare source to predict potential ocular hazards ranging from temporary after- image to more severe possible retinal damage. These results are presented in a simple, easy -to - interpret plot that specifies when glare is predicted to occur throughout the year, with color codes indicating the potential ocular hazard. Keenesburg, CO Glare Study Results October 3, 2023 Update 7 Colliers Engineering & Design Background Information Glint is typically defined as a momentary flash of bright light, often caused by a reflection off a moving source. A typical example of glint is a momentary solar reflection from a moving car, or "catching" something bright out of the corner of your eye. Glare is defined as a continuous source of bright light. Glare is generally associated with stationary objects, which, due to the slow relative movement of the sun, reflect sunlight for a longer duration. The difference between glint and glare is duration. Industry -standard glare analysis tools evaluate the occurrence of glare on a minute -by -minute basis; accordingly, they generally refer to solar hazards as 'glare.' The ocular impact of solar glare is quantified into three categories (Ho, 2011): 1. Green - Unproblematic shine. Low potential to cause after -image. This type of glare can be compared to noticing something shiny in the distance. 2. Yellow - Potential to cause temporary after- image (flash blindness). This type of glare is much like sunrise and sunset glare for drivers who struggle to find the perfect angle for car visors so they can continue to operate their vehicle safely while traveling through areas of such glare. a. Standard levels of yellow glare can, for the most part, be handled with relative ease utilizing slatted fencing or local - foliage landscape mitigation measures. b. Only extremely high levels of this type of glare (in the area of the chart to the right labeled as "direct viewing of the sun" which is uncommon to find with PV installations) would be considered an insurmountable hurdle to a PV installation of any size. c. High levels/intensities and long durations are different factors. 1.E+03 1.E+02 1_E+01 E 1.E+00 1.E-01 co 1.E-02 co 1.E-00 co w 1.E-04 1.

Red - Potential to cause retinal burn (permanent eye damage). PV modules do not focus reflected sunlight and therefore retinal burn (RED glare) is typically not possible. d. This is the ONLY type of glare that would be considered an insurmountable hurdle to a PV installation of any size. These categories assume a typical blink response in the observer. Keenesburg, CO Glare Study Results October 3, 2023 Update 8 Colliers Engineering & Design Note that retinal burn is typically not possible for PV glare since PV modules do not focus reflected sunlight. They are, in fact, designed to absorb as much sunlight as possible. To further put glare into perspective, the following is presented. YELLOW glare such as in the graphic to the right could only be seen when standing directly next to project panels at the perfect angle when the sun is in a perfect place —indeed the point of a photographer standing directly by these panels and waiting for the perfect moment to capture this image. It is also possible that the panels in the picture shown do not have an anti -reflective coating. Solar panel showing solar glare GREEN glare, as illustrated directly to the right, is the more common o ccurrence with solar projects a n oticeable shiny area (in the n orthwest area) as compared to panels where the sun is not quite in perfect alignment yet. Even so, the effect of this noticeable shine to certain areas of the project area is still seen from a relatively close up vantage point and at the optimal height this image was captured, possibly by a drone. A similarly sized project in the distance, closer to the horizon of the photo would be unlikely to show even the levels of green glare that the system in the foreground reflects. Keenesburg, CO Glare Study Results October 3, 2023 Update 9 Colliers Engineering & Design Executive Summary The purpose of the glare study on the proposed solar project in Keenesburg, Weld County, CO is to provide feedback regarding areas that may warrant closer examination in order to mitigate possible problematic predicted glare to the businesses, residences, and roads surrounding the project area. Information was provided by Manhard Consulting and their client in order to complete this study. The project's single -axis tracker panels were programmed to a 0 -degree tilt axis facing south at 180° with a maximum tracking angle of 60 -degrees, a resting angle of 35 degrees, and an assumed midpoint height of 6 -feet from the ground. It was further assumed that these panels are constructed of Smooth Glass with an Anti -Reflective coating. Twenty-eight (28) Observation Points were placed at different points around the site and programmed to an average height of 5 and a half (5.5) feet to model someone standing in these spots, and to a height of 15 feet to model a 5.5 -foot person standing on the second floor of a home/business with 8 -foot ceilings and a 1.5 -foot plenum space. NOTE: Where buildings are obviously identifiable as single -story structures, only the 5.5 -foot height is programmed. Twenty (20) Route Receptors were programmed for two-way traffic to heights of 4.5 feet and 8.5 feet, effectively representing the eyeline of an average person sitting on/in any vehicle from a bike to a motorcycle, a standard car or SUV, through to the approximated seated height in the cab of an 18 - wheeler truck. Keenesburg, CO Glare Study Results October 3, 2023 Update 10 Colliers Engineering & Design While it is impossible to study every possible point and/or angle surrounding a photovoltaic (solar) project, Collier's Engineering & Design (CED) has modeled the project and surrounding areas as best as possible with the most likely points of concern. When PV arrays are spread out over large and/or separated surface areas it may reduce the accuracy of certain calculations. Glare calculations via ForgeSolar utilize the PV footprint centroid, rather than the glare -spot location, due to analysis method limitations. Additional analyses of total array sub -sections can generally provide more accurate information on expected glare. In order to reduce possible flaws to the results of this analysis, CED will run an overall glare map on smaller field sections to find cumulative glare readings and then, where necessary, proceed to break down each area into individual parcels in order to properly estimate the glare of each. In this way, we can ensure the most accurate possible results. PV modules do not focus reflected sunlight and therefore retinal burn is typically not possible. They are, in fact, designed to absorb as much sunlight as possible. Modern photovoltaic panels actually cause less glare than standard home window glass; and research has shown that they reflect less light than snow, white concrete and energy -efficient white rooftops. Keenesburg, CO Glare Study Results October 3, 2023 Update 11 Colliers Engineering & Design The YELLOW glare we are looking to identified with this study is much like sunrise and sunset glare for drivers who struggle to find the perfect angle for car visors so they can continue to operate their vehicle safely while traveling through areas of such glare. In general, photovoltaic panel systems of any size produce some glare predominately during early sunrise and sunset throughout the Spring through Fall months although glare is possible throughout each day as well as throughout the e ntire year. After examining each point and then factoring in additionally recommended foliage, distance, and e levation changes, points where predicted glare is blocked by natural obstructions were removed from the listing of points to be examined more closely. Finally, if any glare continues to be predicted in any area, this analyst will address the areas that present the most possibility for likely glare. ASSUMPTIONS • Times associated with glare are denoted in Standard time. For Daylight Savings, add one hour.* • Glare analyses do not account for physical obstructions between reflectors and receptors. This includes buildings, tree cover and geographic obstructions. • Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum. • 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. Keenesburg, CO Glare Study Results October 3, 2023 Update 12 Colliers Engineering & Design Results of this Study RESULTS at 35 Degree Resting Angle Tracking panels set to +/- 60 degrees with a mid -point axis of 6 -feet high and a resting angle of 35 degrees. There are no noticeable naturally occurring local foliage obstructions. Results of this scenario shows no glare. Keenesburg, CO Glare Study Results October 3, 2023 Update 13 Colliers Engineering & Design Summary of FAA -Level Flight Path Screening Results Though there are no FAA local airports in the proposed project area, a local landing strip was reviewed. FEDERAL AVIATION ADMINISTRATION (FAA) SCREENS An FAA -level glare analysis was performed and a report specific to this request can be found in Appendix A of this report. Each operational flightpath was programmed with specified alignment, glide path, and threshold crossing height. Keenesburg, CO Glare Study Results October 3, 2023 Update 14 Colliers Engineering & Design Analyses are run from threshold crossings to two miles out taking the pilot's visibility from the cockpit into consideration. These visibility settings were programmed at a 30 -degree maximum downward viewing angle and a 50 -degree azimuthal viewing angle. Threshold crossing heights of 25 feet were programmed for both approaches. There is no air traffic control tower at this facility, however a theoretical tower at a height of 25 feet was programmed. Per the FAA's most recent 2021 policy regarding solar around airports, this project PASSES. Glare Policy Adherence The following table estimates the policy adherence of this glare analysis according to the 2021 U.S. Federal Aviation Administration Policy: Review of Solar Energy System Projects on Federally -Obligated Airports This policy may require the following criteria be met for solar energy systems on airport property: • No glare of any kind for Air Traffic Control Tower(s) ("ATCT") at cab height. • Default analysis and observer characteristics, including 1 -minute time step.

Results are informational only. On May 26, 2021, the Federal Aviation Administration updated their policies regarding the installation of solar on and/or near regulated airports/airstrips. While this policy of the Federal Aviation Administeration does not apply to solar energy systems on airports that do not have an Air Traffic Control Tower (ATCT), airports that are not federally - obligated, or solar energy systems not located on airport property —it does provide a high benchmark to meet to ensure that proposed solar installations do not create glare that poses any sort of safety hazard for pilots. Keenesburg, CO Glare Study Results October 3, 2023 Update 15 Colliers Engineering & Design The brief of this FAA policy update states: "The Federal Aviation Administration (FM) published a final policy aimed at ensuring that airport solar projects don't create hazardous glare. The policy requires airports to measure the visual impact of such projects on pilots and air traffic control personnel. The policy applies to proposed solar energy systems at federally obligated airports with control towers. Federally obligated airports are public airports that have accepted federal assistance either in the form of grants of property conveyances As more airports invests in this technology for environmental and economic benefits, the FM wants to make sure that the reflection from the systems glass surfaces do not create a glare that poses a safety hazard for pilots and air traffic controllers. Under the final policy, airports are no longer required to submit the results of an ocular analysis to FM. Instead, the airport must file a Notice of Proposed Construction or Alteration Form 7460-1 that includes a statement that the project will not cause any visual impact. The airport submits the form to the FM for review and approval. The FM relies on the airport to confirm via the form that it has sufficiently analyzed the potential for glint and glare and determined there is no potential for ocular impact to the airport traffic control tower cab. If any impacts are discovered after construction, the airport must mitigate the impact at its expense. The airport may also face compliance action for failure to address visual impacts that create aviation safety hazards. As such, the agency encourages an airport to conduct sufficient analysis before installing a solar energy system. The FM is also withdrawing the recommended tool for measuring the ocular impact of potential glint and glare effects on pilots and air traffic controllers." Additionally: "Initially, FM believed that solar energy systems could introduce a novel glint and glare effect to pilots on final approach. FM has subsequently concluded that in most cases, the glint and glare from solar energy systems to pilots on final approach is similar to glint and glare pilots routinely experience from water bodies, glass -facade buildings, parking lots, and similar features. However, FM has continued to receive reports of potential glint and glare from on -airport solar energy systems on personnel working in ATCT cabs. Therefore, FM has determined the scope of agency policy should be focused on the impact of on - airport solar energy systems to federally -obligated towered airports, specifically the airport's ATCT cab."

"Yellow" glare is glare with potential to cause an after -image (flash 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. The algorithm does not rigorously represent the detailed geometry of a system; detailed features such as gaps between modules. variable height of the PV array, and support structures may impact actual glare results. However, we have validated our models against several systems, including a PV array causing glare to the air-traffic control tower at Manchester -Boston Regional Airport and several sites in Albuquerque, and the tool accurately predicted the occurrence and intensity of glare at different times and days of the year. Several V1 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. This primarily affects V1 analyses of path receptors. Random number computations are utilized by various steps of the annual hazard analysis algorithm. Predicted minutes of glare can vary between runs as a result. This limitation primarily affects analyses of Observation Point receptors, including ATCTs. Note that the SGHAT/ ForgeSolar methodology has always relied on an analytical, qualitative approach to accurately determine the overall hazard (i.e. green vs. yellow) of expected glare on an annual basis. The analysis does not automatically consider obstacles (either man-made or natural) between the observation points and the prescribed solar installation that may obstruct observed glare, such as trees, hills, buildings, etc. 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.) The variable direct normal irradiance (DNI) feature (if selected) scales the user -prescribed peak DNI using a typical clear -day irradiance profile. This profile has a lower DNI in the mornings and evenings and a maximum at solar noon. The scaling uses a clear -day irradiance profile based on a normalized time relative to sunrise, solar noon, and sunset, which are prescribed by a sun -position algorithm and the latitude and longitude o btained from Google maps. The actual DNI on any given day can be affected by cloud cover, atmospheric attenuation, and other e nvironmental factors. The ocular hazard predicted by the tool depends on a number of environmental, optical, and human factors, which can be uncertain. We provide input fields and typical ranges of values for these factors so that the user can vary these parameters to see if they have an impact on the results. The speed of SGHAT allows expedited sensitivity and parametric analyses. The system output calculation is a DNI-based approximation that assumes clear, sunny skies year-round. It should not be used in place of more rigorous modeling methods. 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. Glare locations displayed on receptor plots are approximate. Actual glare -spot locations may differ.

Standard time. For Daylight Savings, add one hour. • Glare analyses do not automatically account for physical obstructions between reflectors and receptors. This includes buildings, tree cover and geographic obstructions. • Detailed system geometry is not rigorously simulated. • The glare hazard determination relies on several approximations including observer eye characteristics, angle of view, and typical blink response time. Actua values and results may vary. • The system output calculation is a DNI-based approximation that assumes clear, sunny skies year-round. It should not be used in place of more rigorous modeling methods. • Several V1 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 combine( area of adjacent sub -arrays can provide more information on potential glare hazards. (See previous point on related limitations.) • Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum. • Glare locations displayed on receptor plots are approximate. Actual glare -spot locations may differ. • Refer to the Help page for detailed assumptions and limitations not listed here. https://forgesolar.com/projects/17085/configs/102006/ 44/44 Colliers Engineering & Design Colliers Engineering & Design is a trusted provider of multi -discipline engineering, design and consulting services providing customized solutions for public and private clients through a network of offices nationwide.

This is essential to help ensure your suppression system is ready to respond in a fire emergency. But maintenance costs can be significant over the life of a system and must be considered early on. Because Stat-X fire suppression has no distribution piping or pressurized agent vessels, maintenance activity is minimized. This dramatically decreases total cost of ownership compared to other systems. MAINTENANCE COSTS OVER 10 YEARS (Service call: $785/day) Stat-X Dry Chemical CO2 Halocarbon Inert Gas Water Mist 0 $5,000 $10,000 $15,000 $20,000 $25,000 $30,000 Water Mist Flow alarm & drain test Quarterly Clean or replace screens Semi-annual Nozzle water test flow Annual Valve tear -down, inspect 5 -years Halocarbon Test FACP actuation, weigh cylinders Semi-annual Blow out piping 2 -years Hydrostatic test hose 5 -years Dry Chemical Test FACP actuation, blow out piping Semi-annual Tear -down & replace agent 6 -years C02 Test FACP actuation, check pressure & agent quantity Semi-annual Hydrostatic test cylinder, refill unrecovered agent 5 -years Inert Gas Test FACP actuation, check pressure & agent quantity Semi-annual Hydrostatic test cylinders, refill unrecovered agent Test FACP actuation, examine Stat-X hardware 5 -years Semi-annual The number of required maintenance tasks, their complexity and frequency determine costs over time. Tasks shown above are taken from UL -listed design, installation, operation and maintenance manuals from various manufacturers. By comparison, Stat-X system inspection and maintenance has fewer tasks, saving both time and labor. Fire Professionals Are Switching to Stat-X! Fire safety professionals who do cost -to -benefit risk analysis quickly realize Stat-X fire suppression is the most economical system, offering the most effective fire protection, for many special hazard applications. The inherent flexibility of design combined with equipment and labor savings allows them to enhance coverage for currently protected assets and add coverage to previously neglected areas. What Our Customers Are Saying Stat-X protecting one of our CNC machines discharged due to fire, suppressing it. The area was unmanned and the automatic system stopped the fire from spreading. We were up and running again fast! - Manufacturer, Geneva, IL It works wonders. One Stat-X First Responde - Firefighter, Deer Park, NY knocked down the fire. They are life savers. After researching available special hazard systems for the very best protection as well as compliance with safety and environmental issues we found Stat-X technology as the product leader. - Engineer, Leicestershire, UK Traditional Special Hazard Fire Protection Centers Around Two Technologies Water deluge and chemical agent fixed systems protect high value assets and processes not possible with sprinkler -based fire protection. But this technology remains basically unchanged over the years; a supply of agent is stored under pressure, released through a piping distribution network, floods the space, and suppresses the fire. Traditional piped systems require costly installation adaptations like: • Extra space for agent containers and piping ■ Robust fixtures to handle weight and discharge ■ System isn't easily reconfigured if space changes ■ Extensive and frequent maintenance burden ■ Special measures for recharging at remote sites IN Inert Gas (NFPA 2001) • Dry Chemical (NFPA 17) IN Carbon Dioxide (NFPA 12)x. ■ Halocarbon Gas (NFPA 2001) Scat -X° Aerosol technology An Effective and Economical Alternative For safety professionals who need effective and economical special hazard fire protection, Stat-X aerosol technology delivers up to 35% savings Stat-X aerosol technology is different: NO distribution piping, manifold, or nozzles NO floor space requirement or shoring up for weight ■ NO special handling for compressed gas cylinders NO venting or ceiling tile clips for discharge forces ■ NO solenoid actuators, control heads, or hoses NO water drains or pipe freeze protection NO system pressurization or room integrity tests in equipment and lifecycle costs compared to traditional systems. This is due to lower initial expense plus minimal ongoing service costs. How it Works Stat-X devices are termed condensed aerosol agent generators because they generate an ultra -fine suspension of highly ionized potassium fire -fighting particles upon actuation. The key elements in the generation process are: Device is sealed and stable until actuated Actuator at top energizes proprietary compound, creating aerosol agent by exothermic oxidation Build-up of ultra -fine particles and nitrogen gas breaks membrane seal and exits through ports Discharge fills protected area with a soft suspension of Stat-X agent without super -pressurizing space Potassium ions combine with fragments of combustion, inhibiting the fire chain reaction Agent particles also absorb heat from the fire and form inert gases upon decomposition Minute Stat-X agent particles (≤2 pm) remain in suspension afterwards, helping check re -ignition Post -fire area is easily vented and cleaned, with no harmful byproducts generated The superior effectiveness of condensed aerosols is due to a unique set of characteristics unmatched by other special hazard agents. This is why it is by far the most efficient fire suppression agent by weight. LESS AGENT FOR THE SAME HAZARD SPACE For a 2,550 ft3 (72.2 m3) hazard volume: 1 Stab (11 lb/5 kg) Dry Chemical Halocarbon (50 Ib/22.7 kg) (130 lb/59 kg) CO2 Inert Gas (160 lb/73 kg) (114 lb/52 kg) Key Approvals Worldwide Aerosol fire suppression technology is well-known throughout Europe and Asia. In the past few years, more fire protection engineers in the Americas are recognizing its worth for protecting special hazards. Norms such as NFPA 2010: Standard for Fixed Aerosol Fire Extinguishing Systems and UL 2775: Fixed Aerosol Extinguishing Systems Units now govern its use in a wide variety of applications. Most efficient fire suppression by weight Effective on A, B & C Class fires Negligible residue, minimal clean-up Non-toxic, EPA listed halon substitute Stat-X technology is also listed by the USA Environmental Protection Agency as a Halon alternative under its Significant New Alternatives Policy (SNAP) program. It has no Ozone Depletion Potential (ODP) and zero effective Global Warming Potential (GWP) meaning Stat-X agent is not prone to future bans like many halocarbon agents.

Access to Project Site 5 ii Emergency Response Plan 1 General Information The following Emergency Response Plan has been established to ensure Prospect and Janus Solar + Storage Projects can adequately and effectively respond to an emergency during the construction and/or operations phases of the project. 1.1 Project Description Horus Energy is proposing to construct and operate the Prospect and Janus Solar + Storage Projects (the "Projects"), a 200 MWac solar energy generation with a 100MW battery energy storage and an 80 MWac solar energy generation with a 20MW battery energy storage located in Weld County. The Project is further described as follows: 1. The Projects are a combined 280 MWac solar PV facility and 120MW battery energy storage facility (BESS) located on approximately 2,200 acres of privately -owned agricultural land. 2. The perimeter is planned to be fenced and accessible via distinct access points during the construction phase. 3. Access throughout the site is provided by gravel surfaced access routes. 4. The Project shall consist of approximately 582,000 solar photovoltaic modules. The PV modules are mounted on a single axis tracker system. 5. The project will contain 79 inverter/transformer stations and 29 BESS inverter stations. 6. An Operations and Maintenance facility will be located adjacent to the substation and will house safety equipment. 7. The project will be controlled by telecommunications equipment located in buildings within the substation. 1.2 Emergency Authority and Point of Contact The designated project Emergency Point of Contact ("POC") will be responsible for overseeing emergency service compliance. Their duties will include ensuring that the measures in this plan are clearly communicated to project personnel as well as all agencies that the Project interacts with. In addition, their duties will include compliance with this ERP and that all agencies and appropriate stakeholders (including but not limited to local residents, emergency response units, transmission utility, and project owner) are properly notified in the event notification is required, and that all required plans and reports are prepared and submitted in a timely manner. The Emergency Point of Contact during the construction phase of the Project will be designated as a representative of the Engineering, Procurement, Construction, and Management ("EPCM") contractor. During the operations phase, a site operations manager will assume responsibility for emergency services. Page I 1 Emergency Response Plan Table 1.

This training will include pertinent information regarding hazardous material and fire prevention. 2.1 CommunicationandTrainingProcedures The Emergency P0C will be responsible for ensuring proper training is received by all personnel. The Emergency P0C will maintain a directory of all project participants and subcontractor leadership contacts to adequately communicate any emergency situations. 2.2 Types of Emergencies • Medical Emergency: worker injury or personal medical issue • Fire: wildland/grassfire or electrical fire • Severe Weather/Catastrophic Emergency: tornado, high wind event, blizzard, flood, lightning • Hazardous Material Emergency: chemical spills, equipment failures, environmental conditions dangerous to personnel. • Electrocution: contact with AC or DC conductors or step and touch hazards • Vehicle: vehicle incident 3 Emergencies 3.1 Project Team The Engineering, Procurement, Construction, and Management (EPCM) Contractor for the Project will be determined at a later time once the Project is permitted. The Project team will consist of: Table 4. EPC Project Team Position Organization Name Telephone EPC Project Manager Construction Superintendent Engineering Lead Environmental Lead The EPCM Contractor will provide updated contact information prior to mobilization to site and distribute during site orientations given to each employee. Upon completion of construction, the Operations Page I 5 Emergency Response Plan Contractor will assume control of the site, at such time each contractor will ensure proper transition and updating of this Plan has occurred and that all personnel are made aware of any changes. 3.2 Emergency Medical Care Only provide care to injured persons if it is safe to do so and you are trained in First Aid/CPR or for the care required. Each Supervisor or Team Leader will identify each member of their respective crews who are First-Aid/CPR trained. In the event of a major-medical emergency, on -site personnel who are professionally trained should immediately assess the patient in conjunction with immediate notification to 9-1-1 and/or local or onsite Emergency Medical Services. 3.3 Equipment Requirements The following equipment will be kept on -site (at a minimum) to support on -site care: • First Aid Kits: standard kits containing supplies for care of minor injuries or ailments. One (1) kit per crew and one (1) kit in each jobsite office • Automated External Defibrillator (AED): portable device capable of restoring normal cardiac rhythm during cardiac arrest. One (1) in the jobsite office, One (1) in designed Site Safety Manager vehicle. • Emergency use non-conductive rescue hook. One (1) in each jobsite office, One (1) in designed Site Safety Manager vehicle, One (1) at substation once energized. All First Aid equipment should be stored in clean, dry area, accessible for regular inspection by crews and have documentation indicating equipment is in proper working order and supply is adequate. Replace any questionable, expired or exhausted supplies immediately. 4 Fire Protection and Prevention 4.1 Purpose & Need for Fire Prevention Plan (FPP) • Eliminate the potential risks and/or causes of fires. • Prevent loss of life and property by fire • Educate employees to promote a safe environment. • Be prepared should a fire occur. • Outline a procedure to follow for the safety of the individuals on site at the time of the occurrence. • Identify risk factors and hazards. • Set up proper storage procedures, training, and identification of personnel responsible for maintaining and servicing the equipment and systems on site that are used to prevent and/or control a fire. 4.2 Responsibilities and Procedures Safety is everyone's responsibility on site. All employees are to be trained and should know how to prevent and respond to a fire emergency. All employees must: • Complete an on -site training program identifying the fire risks for the project site. Page I 6 Emergency Response Plan • Know the protocol and follow emergency procedures should an event occur. • Review and report potential fire hazards to the Onsite Primary Contact. 4.3 Hazards Associated with Solar PV Photovoltaic (PV) solar arrays present a unique challenge for fire fighters. Unlike a typical electrical or gas utility, a PV array and collection system does not have a single point of disconnect. Whereas there are disconnects that will de -energize select parts of the system, if the PV panels are illuminated, the individual strings of PV panels are energized and capable of producing up to 1,500 volts. Below is a summary of the hazards associated with firefighting activities in photovoltaic solar arrays: • Shock hazard due to the presence of water and PV power during suppression activities • Outdoor rated electrical enclosures may not resist water intrusion from the high-pressure stream of a fire hose. • PV panels damaged in the fire may not resist water intrusion. • Damaged conductors may not resist water intrusion • Shock hazard due to direct contact with energized components • No means of complete electrical disconnect • Multiple power sources • Due to the dangers presented above, it is not typical to practice fire suppression by means of water inundation within solar PV arrays. 4.4 Hazards Associated with Battery Energy Storage Systems In 2020, the American National Fire Protection Association published NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, which addresses the dangers of toxic and flammable gases, stranded energy, and increase fire intensity associated with stationary energy storage systems. In general, the hazards inherent in BESS include fire and explosion, chemical, electrical, stranded or stored energy, and physical hazards. These hazards vary based on the technology used and the operating conditions. The Project currently contemplates the use of lithium -ion (Li -ion) batteries. Hazards specific to Li -ion batteries under normal conditions include: • Fire due to latent defects in the cells themselves or design issues related to the system controls • Electrical hazards due to the risk of direct contact with high voltage equipment or high battery energy levels • Stranded or stored energy hazards can exist if the batteries cannot be discharged or isolated for routine maintenance or replacement Hazard considerations for Li -ion batteries under abnormal/emergency conditions include: • Fire due to short circuiting and thermal runaway conditions if batteries are not maintained at appropriate operating parameters due to abnormal conditions • Chemical hazards may be present via off -gassing or hazardous vapours • Electrical hazards may exist if the BESS is at hazardous voltage and energy levels • Stranded or stored energy under normal and abnormal conditions are similar. Damaged batteries may contain stored energy, which may pose a hazard during disposal. • Physical hazards may exist due to overheating parts, damaged moving parts (e.g. fans) Page i 7 Emergency Response Plan 4.5 Considerations for Emergency Responder Pre -incident Planning The deployment and long-term operation of utility -scale BESS poses an additional challenge for rural first responders and fire fighters. NFPA 855, Annex C contains valuable information for first responders to safely and effectively respond to incidents that involve battery energy storage systems. Fire departments are encouraged to develop pre -incident plans for responding to fires, explosions, and other incidents associated with BESS installations and include: • Awareness and understanding of procedures involved with the BESS facility operations and ERP • Knowledge of technology (battery type) and the related hazards and methods for responding to the particular type of BESS • Identifying the locations of all electrical disconnects • Understanding that there may be stored or stranded electrical energy in the BESS that cannot be discharged or isolated • Understanding procedures related to dealing with damaged BESS equipment. • Contacting the Operations and Maintenance Manager or BESS subject matter expert to control or remove damaged equipment 4.6 Overheated Battery If a fault occurs in the BESS and overheating of a battery cell(s) continues unchecked, damage may occur resulting in swelling, off -gassing, fire, or even explosion. Response to an overheated battery should include the following steps as outlined in NFPA 855, Annex C: • Isolating area of all non -essential personnel • Reviewing the status of the BESS buildings/containers, BESS alarm system, and facility with available system monitoring data • Performing air monitoring of any connected spaces • Identifying the location of overheated battery(s) • Isolating the affected battery, string, or entire system based on the extent of damage by opening battery disconnect switched where possible • Contacting the Operations and Maintenance Manager or BESS subject matter expert • Continue temperature monitoring to ensure mitigation or overheating condition 4.7 Battery Energy Storage System Fire Response Response to electrochemical BESS related fires should include the following steps: • System isolation and shut down • Hazard confinement and exposure protection • Fire suppression • Ventilation 4.7.1 Understanding Thermal Runaway Conditions Fires in electrochemical energy storage systems are often a result of thermal runaway, whereby the batteries create heat that cannot be dissipated, resulting in dynamic temperature increase. Fire responders should be prepared for toxic and potentially explosive gas release Page I 8 Emergency Response Plan 4.7.2 Battery Energy Storage System Suppression Agents For Li -ion battery fires, water is the preferred suppression agent due to its immediate cooling capacity, availability, and ease of onsite storage and transport. Firefighting foams are not considered to be effective because they lack the ability to cool and can conduct electricity. Foams may also contribute to thermal runaway issues by insulating the burning materials and exacerbating heat rise. Dry chemical powders used in firefighting may extinguish visible flame but, similar to foams, do not provide cooling to heated battery equipment. Thermal runaway inside the battery may continue potentially causing reignition. 4.7.3 Air Monitoring Battery fires generally resemble plastic fires in terms of emission of toxic gases including CO, HCI, HF, HCN, Benzene, and Toluene. Li -ion battery fires will have short peaks of toxicity as individual cells randomly fail. However, battery fires, even once extinguished, continue to emit CO as long as the batteries remain hot. Air monitoring during and after a BESS related emergency incident should be a priority for first responders. The BESS will contain a manufacturers air -monitoring system; however, it is recommended that fire responders use gas detection equipment to determine the presence and/or levels of toxic gases. Continued monitoring of CO from BESS fires, especially in enclosed spaces, and the continued use of personal protective equipment, including self-contained breathing apparatus, until CO levels are shown to be at normal levels. These practices may include monitoring for HCI, if applicable or possible. 4.8 Initial Fire Response 4.8.1 Small Fires Small fires that are in the early stage and can be controlled with a fire extinguisher. An example would be a small trash can fire. In the event of a small fire at the project: The person discovering the fire should immediately call the onsite supervisor, call 9-1-1 and notify the appropriate personnel. All non -essential personnel should be removed from the hazard area. Fire extinguishment with a fire extinguisher or other means should be attempted if the person has been trained in the use of fire extinguishers and it is safe to do so without placing themselves in danger. Evacuate to the muster point or designated meeting area. All work in the area should cease immediately, take steps to safely shut down equipment, exit the evacuation area, and report to the muster point or designated meeting area. No employees are permitted to re-enter the site until the incident commander deems it safe and will issue an "All Clear" when it is safe to do so. 4.8.2 Large Fires In the event of a large stage fire at the project: • The person discovering the fire should immediately contact the onsite supervisor and call 9-1-1 to report the fire. Onsite personnel should not attempt to fight large fires. • All personnel should be removed from the immediate danger area in anticipation of an evacuation. Page i 9 Emergency Response Plan • The Onsite Primary Contact will respond to the scene and ensure that the fire department has been dispatched. They will then determine evacuation needs, recruit/dispatch employees to assist with the evacuation and issue the following statement over the radio: "Attention, there is a fire emergency at (location name). Please evacuate (the affected area) and report to (designated meeting area). • At this point, all employees in the affected area will stop work immediately, take steps to safely shut down equipment, exit the evacuation area, and report to the designated meeting area. • In this scenario, fire extinguishers are to be used for escape purposes only. • The Onsite Primary Contact will take the necessary steps to ensure that no employee re-enters the evacuated area until the Fire Department arrives and assumes command. • No employee is required or permitted to place themselves in harm's way in order to facilitate extinguishment, evacuation, or rescue. All rescue operations will be performed by trained professionals upon their arrival. • The Onsite Primary contact will provide notification to arriving Emergency Services that all employees are present and/or accounted for. • The Onsite Primary Contact will issue an "All Clear" only when the Fire Department informs them that it is safe to do so. 4.8.3 Grass/ Wildland Fire Procedures The site should be free of combustible vegetation with only a ground cover of maintained vegetation adjacent and beneath the solar racking. Flying embers from off -site fire may inundate the area during fire events. The modified fuel areas and project features will resist ignition from ember showers. Ignition of the ground cover could result in a fast moving, but lower intensity fire that burn in a patchy manner on the site beneath the modules. This type of fire would be relatively short -duration as vegetative fuels are consumed rapidly. There would not be a sustained source of heat and or flame as there would be with surrounding wildfires. In the event of a vegetation fire under or near the modules or inverters: DO NOT attempt to extinguish the flames with water or other chemicals as an electric shock or arc could occur. If possible, safely attempt to shut down power at the inverter using the emergency shut off push button. Let the fire burn vegetation and self -extinguish. If flames continue away from modules or inverters, attempt to extinguish flames. 5 Controlling Hazards & Prevention Practices Identification and elimination of conditions that may cause fires is the best method for eliminating injury, loss of life, or loss of property due to fires. Fire prevention at the Project will be promoted by: Educating employees about risks and how to maintain a safe environment Identification of risk factors (ignitions sources, fuel sources) Proper storage procedures Housekeeping and site maintenance to eliminate fuel sources and identify fire risks. Page I 10 Emergency Response Plan All employees, contractors and sub -contractors need to be educated on fire hazards and what procedures to follow to prevent and control fire hazards. Employees need to know how to respond to the fires those hazards might cause. 5.1 Welding and Open Flame / Hot Work Cutting, welding, and open flame work are naturally hazardous. Welding processes may use oxyacetylene gas, electrical current, electron beams, and heat from fuel gas. It is critical that the highest level of attention be given to these activities to prevent fires at a PV power plant. • Cutting and welding are to be done by authorized personnel Welders are to wear eye protection and protective clothing as appropriate • Oxygen -fuel gas systems are to be equipped with listed and or approved backflow valves and pressure -relief devices • Establish a fire watch when required • Maintain an on -site water source, such as a water truck or tank It is important to note that Weld County has experienced dry conditions over a period of several seasons creating extreme fire hazards due to fine fuel moisture content and high fire rate of spread. 5.2 Class "A" Combustibles These combustibles consist of common materials (wood, paper, cloth, rubber, and plastic) that can act as fuel and are found on most work sites. To handle Class A combustibles safely to prevent fires: • Dispose of waste daily (i.e. cardboard, wood pallets, packing materials etc.) • Use trash receptacles with covers • Keep work areas clean and free of combustible materials • Store materials in the proper storage containers • Do a periodic check of the job site to make sure combustibles are being handled correctly Water and multi -purpose dry chemical (ABC) are approved fire extinguishing agents for Class A Combustibles. 5.3 Class "B" Combustibles These combustibles include flammable and combustible liquids (oil, grease, tar, oil -based paints and lacquers) flammable gases, and flammable aerosols. To handle Class B combustibles safely to prevent fires: • Use only approved pumps (with suction from the top) to dispense liquids from tanks, drums, barrels, or similar containers (or use approved self -closing valves or faucets) • Do not dispense Class B flammable liquids into a container unless the nozzle and container are electrically interconnected by contact or bonding wire. Either the tank or container must be grounded. Page I 11 Emergency Response Plan • Store, handle, and use Class B combustibles only in approved locations where vapors are prevented from reaching ignition sources such as heating or electric equipment, open flames, or mechanical or electric sparks • Do not use a flammable liquid as a cleaning agent inside a building (the only exception is in a closed machine approved for cleaning with flammable liquids) • Do not use, handle, or store Class B combustibles near exits, stairs, or any other areas normally used as exits • Do not weld, cut, grind, or use unsafe electrical appliances or equipment near Class B combustibles • Do not generate heat, allow an open flame, or smoke near Class B combustibles • Know the location of and how to use the nearest portable fire extinguisher rated for Class B fire 5.4 Class "C" Combustibles Class C fires are fires that involve energized electrical equipment. In the event of a Class C fire, ALWAYS de -energize the circuit(s) supplying the fire, and then use a non-conductive extinguishing agent such as carbon dioxide. A multi -purpose dry chemical (ABC) extinguisher can also be used on Class C fires. Do not use water, foam or other electrically conducive agents when fighting electrical fires. Once the electricity is shut down to the equipment involved, the fire generally becomes a standard combustible fire. 6 Employee Training & Education Personnel shall be trained in the practices of the fire safety plan relevant to their duties. Construction and maintenance personnel shall be trained and equipped to extinguish small fires to prevent them from growing into more serious threats. All employees will have to confirm that they understand the function and elements of the fire safety plan, including types of potential emergencies, reporting procedures, evacuation plans, and shutdown procedures. Review any special hazards that might occur at the site, such as flammable materials, fuel storage, toxic chemicals, and water reactive substances. Fire safety training should occur during the site safety training. Every employee must take this training before starting work. Training to include: • Employee roles and responsibilities • Recognition of potential fire hazards • Alarm system and evacuation routes • Location and operation of manually operated equipment (fire extinguishers) • Emergency response procedures • Emergency shutdown procedures • Good fire -prevention housekeeping practices and equipment maintenance The project's site safety person as well as the Onsite Primary Contact are responsible for fire safety training. Page I 12 Emergency Response Plan 6.1 Use of Portable Fire Extinguishers • A minimum of one portable fire extinguisher should be provided within 65 meters of anywhere in the work area during construction or heavy maintenance • Fire extinguishers should be inspected monthly • Fire extinguishers should not be obstructed and should be in conspicuous locations 6.2 Site Maintenance & Housekeeping • Combustible material should not be stored in mechanical rooms or electrical equipment rooms • Storage is not allowed in electrical equipment rooms, or near electrical panels • Electrical panel openings must be covered • Power bars must be plugged directly into an outlet and should be for temporary use only • Extension cords and flexible cords should not be substituted for permanent wiring 7 Equipment Fire Safety • All internal combustion engines, both stationary and mobile, shall be equipped with spark arresters. Spark arresters shall be in good working order • Light trucks and cars with factory -installed (type) mufflers shall be used only on roads where the roadway is cleared of vegetation. These vehicle types shall maintain their factory -installed (type) mufflers and catalytic converter shields in good condition • Equipment parking areas and small stationary engine sites shall be cleared of all extraneous flammable materials • The project proponent shall make an effort to restrict the use of chainsaws, chippers, vegetation masticators, grinders, drill rigs, tractors, torches, and explosives to periods outside of the official fire season. When the above tools are used, water tanks equipped with hoses, fire rakes, and axes shall be easily accessible to personnel. • Hot work permit. Activities using open flame heat sources shall be controlled and managed via an approved hot work permit process. A fire watch shall be maintained for one hour after activities that require a hot work permit cease. 8 Emergency Response Project personnel will meet with local emergency response groups to review the Fire Safety Plan, discuss the type of work taking place, duration of project schedule and emergency procedures. The following course of action should be taken if an emergency situation develops: • Evacuation procedures and assembly are contained in the Evacuation plan, which will be posted in all office trailers. Maintain site security and control. • Notify proper emergency services for assistance. Call 9-1-1. Emergency numbers should be posted throughout the site. • Notify all personnel on site through use of radio or other communication devices. • Once emergency personnel have been notified, an employee will then be designated to meet the emergency personnel at the designated gate entrance and then guide them to incident location. Page I 13 Emergency Response Plan 9 Document Amendment and Distribution This ERP will be reviewed: • Annually. • When there is a change of method and/or technology that may require this document to be reviewed and updated. • Following an emergency drill, response, or significant event to which the ERP is relevant All revisions will be documented in Table 5. Revision Status. Table S. ERP Revision Status Revision r Revision Date Issued Date 1 Reason for Modification 0 2023-10-13 Initial Draft 1 2 10 Fire Incident Reporting A fire report should be completed for all fires that occur on or in the vicinity of the site, including all small fires and ignitions, prescribed ecological burn fires and wildfires. If the incident is managed by Weld County Emergency Services, the fire reports from that agency / fire station will be obtained, reviewed and kept on record for monitoring and reporting purposes for the Project. Fire reporting should include details of the following: • Fire name, ID and location • The person / agency responsible for responding to the fire • The command and control arrangements / incident team • A fire map, including a hand sketch or GIS map of the fire perimeter. Fire mapping should include known or suspected ignition point/s, fire perimeter, fire paths, asset damage, islands of unburnt areas, fire control lines, and other information specific to the fire • Fire management/control measures and strategies. This may include a list of equipment, personnel, vehicles utilised and their role (including agencies/equipment/personnel). • Any unintended fire impacts to ecological values or other assets • Follow up action and additional reporting requirements, such as near -miss or injury, effectiveness of the burn, post -fire assessment requirements The annual monitoring for the Project will include a summary of all ecological burns and fire incidents. The fire reports and outcome will also be used to inform an adaptive management approach (e.g. improvements in fire mitigation procedures and/or response procedures) and incorporated as part of the document amendment procedure (refer to Section 9).

Rev. 0.1_202011 03 Environmental Conservation Measures For the Janus Solar Project Prepared For: Horus Energy HORUS ENERGY Horus Asset Management Limited 5900 Balconies Drive Suite 100 Austin, TX Prepared By: LO G A NS 1M PS ON October 2023 Introduction As a national leader in solar energy development, Horus Energy is committed to implementing industry standard design features and Best Management Practices (BMPs) for the Project. In addition, the following environmental conservation measures would be implemented as applicable during the construction, operation, and decommissioning phases of the Project. These measures are meant to guide responsible and reliable Project construction and operation. Many measures can be revised as necessary in an adaptive management approach to achieve optimum environmental protection over the life of the Project. Environmental protection measures are often captured in the form of implementation plans, such as erosion control plans or safety plans. These plans and others are developed as part of Project development, often by the Primary Contractor.

Proper trash removal and storage procedures would be implemented, such as using secured containers and Energy Horus Ecological periodic emptying on the Project site to reduce attraction of scavengers, such as common ravens and coyotes. Construction Contractor X ECO-9 Resources Construction CPW If construction occurs during the typical migratory bird breeding season in northern Colorado (generally February Energy Horus 1 to July 31), preconstruction surveys would be performed for active nests, including raptor nests, to avoid CPW disrupting migratory birds during the breeding season. Eagles and owls begin breeding activities earlier than other USFWS species (prior to February 1). Surveys for these species would be conducted as appropriate depending on construction timeframes. A qualified biologist would survey the Project area for nesting migratory birds within five days prior to any ground disturbing activity. To minimize impacts to migratory birds (including raptors), active nest sites would be avoided during construction activities, in coordination with CPW. If surveys or other available information indicate a potential for take of migratory birds, their eggs, or active nests, activities would be suspended within a 300-f oot- radius buffer around passerine nests. Raptor nests would be buffered in coordination with CPW and according to Ecological CPW 2020 "Recommended Buffer Zones and Seasonal Restrictions for Colorado Raptors". Contact CPW and the X ECO-10 Resources Construction USFWS for further coordination on the extent of the impact, as needed. The electrical component locations and all aboveground electrical facilities would be designed to provide raptor Energy Horus Ecological and migratory bird protection in compliance with the standards described in Avian Powerline Interaction CPW X ECO-11 Resources Pre -construction Committee (APLIC) documents: APLIC 2006 and APLIC 2012. USFWS Preconstruction wildlife surveys would be conducted, as appropriate. Wildlife monitoring by a qualified biologist Energy Horus would be conducted to ensure that no disturbance would occur to wildlife during construction. The following Construction Contractor species -specific avoidance measures would be implemented. CPW In coordination with CPW, seasonal and spatial wildlife avoidance recommendations would be implemented, as USFWS appropriate. No human encroachment, surface disturbance, or construction activity would occur: • Within 0.25 -mile of an active maternal swift fox den site from March 15 through June 15. • Within and over black -tailed prairie dog colonies from February 1 through July 31. • Within a 0.5 -mile buffer around an active or alternate ferruginous hawk nest from February 1 through July 15. • Within a 0.5 -mile buffer around an active golden eagle nest from December 15 through July 15. • Within a 0.5 -mile buffer around an active prairie falcon nest from March 15 through July 15. • Within a 0.25 -mile buffer around an active Swainson's hawk nest from April 1 through July 31. • Within a 660 -foot buffer around an active burrowing owl nest from March 15 through August 15. These avoidance measures were developed using CPW recommendations provided in the 2021 Colorado Parks and Wildlife Best Management Practices for Solar Energy Development; 2020 Recommended Buffer Zones and X ECO-12 Ecological Resources Construction Seasonal Impacts to Restrictions Wildlife from for Colorado Land Use Development Raptor documents; in Colorado. and 2021 Recommendations to Avoid and Minimize Avoidance' Design Feature Identifier Resource Phase Measure Responsibility/ Agency Coordination X X ECO-13 Ecological Resources Construction Deep would overnight posts structure and be secured would poles foundation be would in checked place be holes and capped for and would wildlife or trenches filled be strong prior with would enough to work sand to not commencing. to prevent be prevent left open entrapment wildlife No overnight open from of posts wildlife. and falling or would in. poles Trenches be covered. would be left left Covers open on site.

Representative Points of Interest Photos from the 2022 Protected Species Site Reconnaissance Survey for Janus Solar, Weld County, Colorado 16 WEST i December 2022 Protected Species Memorandum -Janus Solar INTRODUCTION Horus Capital (Horus) is considering the development of the Janus Solar Project (Project), a photovoltaic (PV) solar energy facility in Weld County, Colorado (Figure 1). The Project Boundary encompasses approximately 669 acres (ac; 271 hectares [ha]) of privately owned land located approximately 13 miles (21 kilometers) northwest of the Denver International Airport (Figure 1, 2). In response to a request from Horus, Western EcoSystems Technology, Inc. (WEST) conducted a preliminary site reconnaissance of the Project Boundary for the presence of habitat that may be suitable for species of concern, including those with federal and state statutory protection. The site reconnaissance was completed by a WEST biologist from October 11, 2022 — October 12, 2022. METHODS The biologist verified National Land Cover Data (NLCD) and conducted reconnaissance review of the Project Boundary for areas of suitable habitat for federal and state -listed species. Prior to the site reconnaissance, land cover types known to provide potentially suitable habitat for protected species were mapped using the latest aerial imagery (Esri and U.S. Department of Agriculture 2014). During the site reconnaissance, areas of potentially suitable habitat were assessed on foot and by driving publicly accessible roads within the Project Area. In addition to documenting habitat type, the biologist also surveyed the Project Boundary for evidence of prairie dog towns and raptor nests. Raptor nests searches included visual scans of elevated features such as tree lines for the presence of large stick nests.

Cultivated crops were the dominant land cover (98%) in the Project Boundary. Herbaceous cover (1.5%) and to a lesser extent, open developed areas also occurred within the Project Boundary (<1%) NLCD 2019; Table 1, Figure 3). The most common crops in -production during the site reconnaissance were sorgam (Sorghum spp.) and winter wheat (Triticum spp.). Locations with herbaceous cover included a livestock pasture, roadside ditches, and low lying areas along the Sand and West Sand Creeks (Figure 3). During the site reconnaissance, cool season grasses such as smooth brome (Bromus inermis) and western wheatgrass (Pascopyrum smithii), as well as the common agricultural weed, burning bush (Bassia scoparia), were observed in abundance. Developed areas included roadways, sparsely vegetated farmstead lots, and associated infrastructure. Desktop land cover estimates were representative of the conditions observed on the ground during the site reconnaissance. Table 1.

A review of available spatial data provided by the Conservation Biology Institute (2022) and Colorado Parks and Wildlife (2022) indicates that the Project Boundary falls entirely within the overall range of both pronghorn (Antilocapra americans) and mule deer (Odocoileus hemionus). CPW designated pronghorn resident population areas and a pronghorn winter range area are adjacent to the Project Boundary (Figure 5). Mule deer resident population area and winter range also intersect the Project Boundary (Figure 6). Evidence for the occurrence of ungulates within the Project Boundary was identified during the site reconnaissance in the form of hoof impressions in the dry Sand Creek streambed. The biologist also documented a hunting stand against a large tree nearby (Figure 4, Appendix A3). The hunting stand faced an open grassy area that had several corncobs scattered on the ground, which may have been placed as a deer attractant (Appendix A3).

The purpose of this letter is to provide trip generation, trip distribution, and project traffic assignment for the construction phase of the proposed solar projects to determine the anticipated increase in traffic attributable to the proposed projects. The proposed Prospect Solar development is located east of Weld County Road 67 (WCR-67), west of WCR-75, north of WCR-2, and south of WCR-6 in Weld County, Colorado. The proposed Janus Solar development is located east of State Highway 79 (SH-79), west of WCR-75, north of WCR-4, and south of WCR-8 in Weld County, Colorado. A vicinity map illustrating the location of Prospect and Janus Solar projects and the surrounding roadway conditions is attached as Figure 1. The Prospect project will consist of a 199 MWac solar facility with supporting infrastructure, whereas the Janus project will consist of an 80 MWac solar facility with supporting infrastructure. A conceptual site plan for the proposed developments is attached. This traffic study identifies the amount of traffic associated with these proposed developments during both construction and operational phases, and the expected trip distribution and traffic assignment. CONSTRUCTION ACTIVITY AND ACCESS Construction activity to assemble the solar facilities is anticipated to commence in 2024. The construction activities each month may vary based on phasing and the size of the phase. This traffic study was prepared analyzing the peak construction traffic during the highest months of activity. Construction will generally follow these steps: • Mobilization • Civil/site preparation • Cable plow/foundations construction • Post install • Racking install • Substation construction • Set major equipment • Module installation • Testing, commissioning, and energization • Demobilization kimley-horn.com 6200 South Syracuse Way, Suite 300, Greenwood Village, CO 80111 303 228 2300 Kimley>>> Horn Prospect and Janus Solar Traffic Study Letter Page 2 Regional access to Prospect and Janus Solar sites will be provided by Interstate 76 (1-76), l- 70, and SH-52. Primary access to the Prospect site will be provided by SH-79, WCR-71, and WCR-73, while direct access is proposed from three full movement accesses along SH-79, one full movement access along the extension of WCR-71, and two full movement accesses along WCR-73. Primary access to the Janus site will be provided by WCR-71, and WCR-73, while direct access is proposed from four full movement accesses along WCR-71 and two full movement accesses along WCR-73. The preferred access route to the Prospect and Janus Solar site is via 1-76 and 1-70. The anticipated heavy vehicle haul route to the sites from 1-76 from the northwest is to travel east on SH-52 toward the project sites. The anticipated haul route to the sites from 1-76 from the north is to travel south along WCR-73 toward the project sites. The anticipated haul route to the sites from 1-76 from the southwest is to travel east along 152nd Avenue, then east along 144th Avenue, then head north along SH-79 toward the project sites. The anticipated haul route to the sites from 1-70 from the south is to travel north along SH-79 toward the project sites. Figure 2 illustrates the vehicle routes to and from the site. TRIP GENERATION Site -generated traffic estimates are determined through a process known as trip generation. The number of trips for the Prospect and Janus Solar facilities was based on anticipated construction activity and the operational phase. In order to study the effect of construction traffic created by the solar facility, the expected trips during the peak period of construction were used as the basis for this study. The peak construction traffic activity is anticipated to occur in 2024. Construction Traffic Generation The typical construction peak season workday will see workers arriving during a four-hour window between 6:00 am and 10:00 am and departing during a three-hour window between 1:00 pm and 4:00 pm. The standard construction hours are anticipated to be 6:30 am to 3:30 pm. The highest proportion of workers will arrive to the site between 6:00 and 7:00 am (half) and depart between 3:00 pm to 4:00 pm (one-third), although the volume will be fairly uniform during the arrival and departure hours. It is anticipated that construction of the facility will include an average of 300 construction workers. At construction peak, there may be up to 450 workers, although the peak hour traffic volumes will remain the same as projected with the traffic spread out further over the arrival and departure peak hours. It is important to note the truck trip generation also includes the volume adjusted for the three (3) passenger car equivalents (PCE) per truck. The following Table 1 identifies the peak construction activity trip generation for the construction of Prospect and Janus Solar facilities. kimley-horn.com 6200 South Syracuse Way, Suite 300, Greenwood Village, CO 80111 303 228 2300 Kimley>>> Horn Prospect and Janus Solar Traffic Study Letter Page 3 Table 1 — Trip Generation: Prospect and Janus Solar Developments For ID .._User Weekday Vehicles Trips Daily Round Trips Daily Trips AM Peak Hour PM Peak Hour In Out In Out Total Total Duty Trucks (15) 15 30 3 1 4 1 2 3 Heavy Water Trucks (15) 15 30 2 0 2 0 2 2 Total Trucks 30 60 5 1 6 1 4 5 PCE Trips 90 180 15 3 18 3 12 15 Passenger Vehicles (300 construction workers) 300 600 150 1 151 1 100 101 Vehicles 330 660 155 2 157 2 104 106 Total Total PCE 390 780 165 4 169 4 112 116 As shown in the table, the Prospect and Janus projects are expected to generate approximately 660 daily trips with 157 of these trips occurring during the morning peak hour and 106 of these trips occurring during the afternoon peak hour during the peak construction activities. This volume of daily traffic of 660 trips are expected to be the highest volume generated during construction of the solar facilities. It is believed that trips generated by the construction of the Prospect and Janus projects will not have major impacts on the transportation patterns or the roads in the area of the project site. Therefore, traffic impacts related to the construction of the solar plant facilities are anticipated to be temporary and accommodated within the existing roadway system. Solar Facility Operational Phase Traffic Generation After the Prospect and Janus projects has been constructed, the number of trips generated by the solar plants is expected to be significantly less than during the construction period. The project will be an unmanned facility with weekly site visits by operational personnel, not exceeding 10 trips per month. On the occasional day when a site visit occurs, the trip generation is anticipated to be one employee entering and exiting throughout the day. Therefore, traffic impacts related to the operation of the solar plant facility are anticipated to be insignificant and not requiring roadway improvements. TRIP DISTRIBUTION AND TRAFFIC ASSIGNMENT Trip distribution is based on the anticipated arrival location of employees along with the delivery route to be used for truck traffic. It is anticipated that truck traffic will utilize SH-52, 144th Avenue, SH-79, and WCR-73 to access the project site. Construction worker trips will be based on the arrival location from place of residence (permanent or temporary). The distribution for construction worker trips was derived based on distances to nearby cities and populations. The City of Fort Lupton is located approximately 24 miles west of the site, the City of Brighton is located approximately 29 miles southwest of the site, the City of Greeley is located approximately 43 miles northwest of the project site. Further south, approximately 47 miles southwest of the site is the City of Denver. Based on these factors, it is anticipated that 35 percent of traffic will be to and from the northwest and southwest and 15 percent of traffic will be to and from the north and south. This traffic was factored for the amount expected to arrive from 1-76 and 1-70. Additionally, since the sites are expected to be constructed one at a time, it was assumed that construction traffic would only be using one construction area at kimley-horn.com 6200 South Syracuse Way, Suite 300, Greenwood Village, CO 80111 303 228 2300 Kimley>>> Horn Prospect and Janus Solar Traffic Study Letter Page 4 a time. Three construction sections were identified, with one area being the section surrounded by SH-79, the second area being the section surrounded by WCR-71, and the third area being the section surrounded by WCR-73. Therefore, trip distribution and traffic assignment were provided separately for accesses along SH-79, WCR-71, and WCR-73. Attached Figure 3 illustrates the anticipated trip distribution for the SH-79 accesses, Figure 4 shows the trip distribution for the WCR-71 accesses, and Figure 5 shows the trip distribution for the WCR-73 accesses. The project traffic assignment for vehicles is shown in attached Figure 6 for the SH-79 accesses, Figure 7 for the WCR-71 accesses, and Figure 8 for the WCR-73 accesses. CONCLUSION In summary, it is believed the temporary construction related vehicle traffic of the Prospect and Janus Solar project can be accommodated by the existing roadway system. Further, trips are negligible during the operational phase of the solar facility. Based on these results, the Prospect and Janus Solar projects are anticipated to have minimal traffic impact.

Waters of the US WEST iv December 2022 Janus Solar Project Confidential Business Information INTRODUCTION Horus Capital (Horus) is proposing the development of the Janus Solar Project (Project), located in Weld County, Colorado (Figure 1). To support development of the Project, Horus contracted Western EcoSystems Technology, Inc. (WEST) to complete a preliminary desktop assessment and conduct a formal wetland and waterbody field delineation survey within the boundaries for proposed solar development (Study Area). The objective of the desktop assessment and field delineation surveys was to identify and delineate the boundaries of the wetlands and waterbodies within the Study Area. STUDY AREA The Project is located in Weld County, Colorado, about eight miles (mi; 13 kilometers [km]) southeast of the town of Keenesburg (Figure 1). To assess impacts to potentially jurisdictional waters at the Project, WEST developed a Study Area based on the most up-to-date Project area map provided by Horus on August 26, 2022. The Study Area consists of 669 acres (271 hectares; Figure 2) and is composed almost entirely of cultivated cropland (98.3%) consisting of sorghum (Sorghum bicolor) and winter wheat (Triticum aestivum) with small areas of herbaceous cover (1.5%) such as smooth brome (Bromus inermis) and kochia (Bassia scoparia; also known as Mexican fireweed) and developed open space of housing and farmsteads (0.2%).

Coleman WEST Figure 2. Study Area for the Janus Solar Project, Weld County, Colorado. WEST 3 December 2022 Janus Solar Project Confidential Business Information METHODS Desktop Review WEST conducted a desktop review of the Study Area by examining the following online spatial data layers: Environmental Systems Research Institute (ESRI) world topographic maps and aerial imagery (2022), soil survey information from the US Department of Agriculture Natural Resources Conservation Service Soil Survey Geographic Database (USDA NRCS SSURGO; 2021), land cover information from the National Land Cover Dataset (NLCD; 2019), US Fish and Wildlife Service National Wetlands Inventory maps (USFWS NWI; 2022), US Geological Survey National Hydrography Dataset data (USGS NHS; 2022), Colorado Wetlands Inventory Mapping Tool (CNHP 2022), Federal Emergency Management Agency (FEMA) National Flood Hazard Layer (FEMA 2016), and current and historic imagery accessed via Google Earth. These data were used to determine areas within the Study Area where field investigation was warranted and to develop a field strategy (e.g., target areas for field verification, areas where formal wetland/waterbody delineations are anticipated, reference points, Study Area access). Field Delineations A WEST biologist, trained in wetland delineations, completed surveys on October 11-12, 2022. In preparation, shapefiles were used to create an ArcGIS online map (AGOL), which was accessible in the field via tablet and used to ensure the Study Area was accurately identified and reviewed during the site visit. NWI polygons and NHD flowlines were also loaded onto the AGOL map for accurate field -verification. Drainage features and potential wetlands/waterbodies identified within the Study Area during the desktop assessment were investigated in the field. Wetlands Wetlands were to be delineated in accordance with the 1987 Corps of Engineers Wetlands Delineation Manual (US Army Corps of Engineers [USAGE] 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0; USAGE 2010). The 1987 manual emphasizes a three parameter approach, which consists of hydrophytic plants (dominant vegetative cover), hydric soils, and wetland hydrology. All three parameters must be present and meet the wetland criteria of each parameter in order for an area to be considered a wetland. Any delineated wetlands would be classified according to methodologies set forth in Wetlands and Deepwater Habitats of the United States (Cowardin et al. 1979). Wetland plant indicator status was determined using the Great Plains regional sub -list of The National Wetland Plant List (USAGE 2020). Paired sample plots (wetland and upland) would be established, and USACE regional datasheets would be completed for each potential wetland within the Study Area. Wetland plots would be located in areas that best represented the vegetation, soils, and hydrology of the site. Additional sample plots would be established in locations where NWI or aerial signatures suggested wetland conditions may be present. Wetlands are typically categorized as one of three common types of wetlands as follows: WEST 4 December 2022 Janus Solar Project Confidential Business Information • Palustrine emergent (PEM) wetlands are defined as inland freshwater areas dominated by hydrophytic vascular plants such as rushes, sedges, forbs, and other herbaceous or grass -like plants. • Palustrine scrub -shrub (PSS) wetlands are defined as inland freshwater areas dominated by woody vegetation less than 20 feet tall, such as willows, alders, and many kinds of saplings. • Palustrine forested (PFO) wetlands are defined as inland freshwater areas dominated by woody vegetation equal to or over 20 feet tall. WEST identified any mapped wetland by a unique ID. The unique ID starts with "w", followed by a two -letter project abbreviation, pj, and then the feature number (e.g., wpj001). In situations where a larger wetland is separated by the presence of a waterbody, the wetland is divided, and an alphabetic identifier is added onto the end of the wetland ID (e.g., wpj001a and wpj001 b). The wetland boundary, sample wetland, and upland plots were surveyed using a Geode global positioning system (GPS) receiver with sub -meter accuracy. Collected paired data points would be assigned a unique ID as described above, but would be followed by "w" for wetland points or "u" for upland points (e.g., wpj001_w or wpj001_u), and then a data point number if more than one pair. All potential wetlands were photo documented within the Study Area. Waterbodies All waterbodies within the Study Area including those identified in the NWI and NHD D datasets, were examined. Waterbodies were delineated and documented in a similar manner as wetlands. The delineator determined if there was presence of an ordinary high water mark (OHWM; USACE 2007). If present, the OHWM of each feature was delineated with a GPS. Linear drainages less than 10 -feet (ft; 3 -meter [m]) wide were delineated with a single line along the centerline of the drainage, and the approximate width was recorded. Linear drainages equal or wider than 10 -ft were delineated along each bank. A GIS technician created polygons from the delineated line features and identified feature width. Each waterbody possessing an OHWM was assigned its own unique ID: • Linear drainages were assigned an "s", followed by a two -letter project abbreviation, pj, and then a feature number (e.g., spj001); • Open water/stock ponds would be assigned an "o", followed by a two -letter project abbreviation, pj, and then a feature number (e.g., opj001). • Linear drainages identified in the field as belonging to one continuous feature were assigned the same ID with an additional alphabetic identifier at the end of their ID (e.g., spj001a and spj001b). WEST 5 December 2022 Janus Solar Project Confidential Business Information Non -Waters and Non Wetlands All NHD D flowlines and NWI polygons that intersected the Study Area, but clearly did not meet the definition of a wetland or waterbody were photo documented and a non -water point was collected. Such points were identified with a "no" followed by a two -letter project abbreviation, pj, and then a feature number (e.g., nopj001). A USACE regional data form was completed for NWI polygons where wetland conditions were not present. Informal Jurisdictional Determination WEST identified wetland and waterbodies that may be regulated by the US Army Corps of Engineers (USAGE). The jurisdictional status of "Waters" are defined by the Waters of the US (WOTUS) definition and Rapanos decision (USEPA 2008). WOTUS is a term used to establish the wetlands and waterbodies that are subject to federal jurisdiction under the Clean Water Act of 1972 (CWA; US Environmental Protection Agency [USEPA] 2021a). The USEPA and USACE are currently interpreting WOTUS consistent with the pre -2015 regulatory regime until further notice (USEPA 2021c). The USEPA has announced intentions to revise the definition of WOTUS and rulemaking is currently underway. For this report, initial analysis of potential jurisdiction will follow the pre -2015 WOTUS definition. As currently defined in the CWA, 40 Code of Federal Regulations 230.3(s) (2010; USEPA 2021 b), wetlands and streams must meet certain criteria related to adjacency to a traditional navigable water (TNW) or other WOTUS, significant nexus to certain WOTUS, or connectivity to a WOTUS to be defined as a jurisdictional WOTUS under the CWA. Waters considered jurisdictional include TNW; interstate waters and interstate wetlands; territorial seas, and tributaries of TNW. Wetlands adjacent to and neighboring WOTUS, or with a significant nexus to TNWs, interstate waters, or territorial seas are considered jurisdictional. Tributaries are jurisdictional if they contribute flow, either directly or through another water, to a WOTUS with relatively permanent flow, or continuous seasonal flow (USEPA 2008). WEST biologists used the field -delineated wetland and waterbody data to assess the potential jurisdictional status of each feature under the pre -2015 WOTUS regulatory guidance. Waterbodies and wetlands within the Study Area were evaluated in accordance with the USA CE Jurisdictional Determination Form Instructional Guidebook (USACE 2007) and current WOTUS criteria to determine the likely jurisdictional status. If a water connection appeared off site, desktop mapping resources were used to review hydrologic connections outside the Study Area, and features were conservatively identified as potential WOTUS if a connection was identified from desktop resources. These initial determinations will be used to inform potential permitting for the Project; however, the USACE is responsible for making official jurisdictional determinations to verify whether Project wetlands or waterbodies fall under federal jurisdiction and CWA regulation. Depending on the permitting needs of the Project, one of three paths forward may be selected to determine jurisdiction: WEST 6 December 2022 Janus Solar Project Confidential Business Information • Approved JD— An approved JD is used to determine the presence or absence of WOTUS (USACE 2016). Upon formal request, USACE personnel will typically visit a site to provide a definitive and legally binding determination regarding both the presence and geographic extent of any jurisdictional aquatic resources at a site. An approved JD is typically requested for projects that will have substantial impacts to wetlands and waterbodies, require a substantial amount of mitigation, or anticipate that a large portion of the impacts would be to wetlands and waterbodies that are not considered WOTUS. In these instances, an approved JD may be the more cost-effective strategy or may streamline the permitting process. Approved JDs are not commonly used for solar projects. • Preliminary JD — A preliminary JD is considered advisory, and is often issued for impacts that will be authorized under an individual permit or general permit requiring pre - construction notification (e.g., Nationwide Permit [NWP] or regional permit; USACE 2016). Preliminary JDs are commonly used when a USACE site visit is either impractical (such as for large projects) or precluded by access constraints, and require supporting documentation and USACE concurrence. Preliminary JDs voluntarily treat all wetlands and waterbodies that would be affected by an activity as though they are WOTUS and calculate impacts and compensatory mitigation accordingly. Therefore, projects with impacts that would be largely temporary often request a preliminary JD because it can expedite the permit process without substantially increasing mitigation costs. Preliminary JDs are occasionally used for solar projects if a permit is required, in areas where potential for public scrutiny is high, or where a state or county reviewer requests it. • No JD — In some cases, projects that will be authorized under Nationwide Permits (NWPs) that do not require pre -construction notification to the USACE may elect to request neither an approved nor a preliminary JD from the USACE (USACE 2016). A "no permit required" letter may also be requested in lieu of a JD if the proposed activities are either not regulated under the CWA or exempt from CWA regulation. Solar projects with impacts that will be authorized under NWPs often use this option because it is the most efficient (and precludes the need for agency involvement). However, there is some risk in not obtaining USACE approval through the JD process. The intent of this wetland and waterbody delineation is to provide a baseline inventory of wetland and waterbody features regardless of jurisdictional status in the Study Area. WEST is also providing a preliminary jurisdictional analysis using the pre -2015 WOTUS definition, based on conditions observed in the field on October 11-12, 2022. RESULTS Desktop Assessment Wetlands and Waterbodies The desktop assessment (sources outlined in Methods, Desktop Assessment) identified 4.5 acres (ac; 1.8 hectares [ha]) of NWI-mapped wetlands within the Study Area (Table 1, Figure 3; USFWS WEST 7 December 2022 Janus Solar Project Confidential Business Information 2022, USGS 2022). The NWI-mapped features (based on Cowardin classification) were riverine streambed. Table 1.

Note: Totals may not sum to values shown due to rounding. The desktop assessment (sources outlined in Methods, Desktop Assessment) identified three NHD-mapped waterbodies totaling 1.0 linear mi (1.6 km) within the Study Area (Table 2, Figure 3; USGS 2022). The NHD features overlap approximately with the NWI riverine wetlands identified above and are known as Sand Creek, West Sand Creek, and an unnamed tributary to Sand Creek. Table 2.

Note: Totals may not sum to values shown due to rounding. Site Visit Condition WEST reviewed National Oceanic and Atmospheric Administration (NOAA) climate data for the Brighton 3 SE weather station to compare current site hydrologic conditions to historical climate data (NOAA 2022). The historical precipitation average was based on a 30 -year period (1991 — 2021). Average precipitation over the 30 -year hydrologic period for the five months (May — September) preceding the survey month (October) was 8.0 in (20.2 cm). Recorded precipitation in 2022 for the 5 -month period preceding the survey was 7.1 in (18.0 cm), or 89 percent of average. Based on this analysis, the Study Area was experiencing below normal hydrologic conditions for the year at the time of the field delineation. During the site visit the Study Area was completely dry and multiple crop fields contained stunted crop plants and bare areas, indicating dry conditions. Wetland and Waterbody Field Delineation The wetland and waterbody field delineation was completed on October 11-12, 2022. No wetlands were delineated in the Study Area. One stream feature (Sand Creek; spj001), was identified and delineated within the Study Area (Figure 5; Table 4; Appendix A). Sand Creek was dry with a sandy bed and defined banks. The OHWM width for both segments is based on the lines delineated for both banks, and the values for this and other characteristics are provided in Table 4. NHD designates the stream as intermittent, while NWI designates the stream as R5UBH (riverine [R], unknown perennial [5], unconsolidated bottom [UB], permanently flooded [H]; USFWS 2022). There were a few areas of herbaceous -covered terraces alongside WEST 11 December 2022 Janus Solar Project Confidential Business Information Sand Creek containing hairy golden aster (Heterotheca villosa), broom snakeweed (Gutierrezia sarothrae) and kochia; these terraces were outside the OHWM but weren't planted to crops. Sand Creek has an OHWM in the Study Area, but review of aerial imagery suggest the downstream connection is severed due to agricultural activities approximately 1.8 mi north of the Study Area. A potential jurisdictional status is assigned as field verification was not performed beyond the Study Area and the USACE's approach to these situations is unclear. Four non -water points were recorded in the Study Area to document NWI and NHD features that did not meet the criteria for wetlands or waterbodies (Appendices A and B). All four non -water points were taken along NWI and NHD lines for West Sand Creek and an unnamed tributary to Sand Creek. While nopj002 was marked outside the Study Area, it is for a NWI riverine line occurring parallel to spj001, as shown in Figure 3. All non -water points were located in vegetated areas containing upland species or planted to crops and lacked an OHWM. Detailed maps of the waterbody boundaries and the non -water and non -wetland points are provided in Appendix A. Photographs of the waterbody and no points are provided in Appendix B. CONCLUSION Sorghum and winter wheat crop production dominate land use within the Study Area. No wetlands were delineated. Within the Study Area, one intermittent stream, Sand Creek, was delineated and is potentially jurisdictional. WEST 12 December 2022 Janus Solar Project Confidential Business Information Table 4.

EXECUTIVE SUMMARY This Socioeconomic Impact and Community Benefit Report has been prepared to gather and document the expected effects of Horus' proposed Colorado Solar Field Project in accordance with the Weld County Charter and County Code. It outlines the Project's alignment with the County strategy and its impacts on land, individuals, and the public in the near - term and future. Solar energy is a responsible and excellent use of private land and delivers very low environmental impacts combined with high social and economic benefits. Operational disturbances in the form of traffic, noise, and glare will be minimal to neighboring residents and communities. Impacts to agricultural operations are expected to be positive due to the maintenance of meadow -life conditions, enhanced with professionally designed pollinator seed mixes and habitat. Oil and gas activity and water rights will not be impacted. Additionally, this report outlines the beneficial economic effects to surrounding communities. Supporting an estimated 1,977 direct and indirect jobs and nearly $13 million in projected property tax revenue, this Project produces significant financial impact on the region that can be used to invest in community assets. This Project will complement the strong Oil and Gas production in Weld County by creating a more stable and reliable power supply, as local generation will be able to maintain power service during extreme weather events that may compromise long distance transmission capacity. This Project will also provide lower cost electricity for residents and businesses. PROJECTED IMPACTS LOF PROJECT Earnings $12518771100 in constre uction ct oning during $61310)200 per year in earnings over the operating life of the project Output $171,955,000 t\Nir in economic output during construction $8,229,700 in economic output over the operating life of the project Jobs 1 997 FTE jobs during construction, equivalent to 1% of the Weld County workforce 102 FTEjobs over operating life of the Project NOW HIRING Net positive Impacts on Agricultural Economy through protection of land from urban development and native pollinator environment to support neighboring agricultural output.

OVERVIEW OF THE U.S. AND STATE SOLAR PV INDUSTRY A. U.S. Solar PV Industry The U.S. solar industry is growing at a significant pace, with systems installed for onsite use at residential, commercial, and industrial properties, and with utility -scale solar powered -electric generation facilities intended for wholesale distribution. According to the Solar Energy Industries Association (SEIA), the industry is expected to triple in size over the next five years, reaching a total installed solar capacity of 375 GW by 2028 (SEIA, 2023). The SEIA is a nonprofit trade association of the solar -energy industry founded in 1974. SETA counts over 1,000 members, including some from Weld County and a large portion of the 399 solar -related companies in the State. SEIA consolidates data sets from multiple industry and third -party sources. In the last decade alone, solar has experienced an average annual growth rate of 24%. Thanks to federal policies like the solar Investment Tax Credit, rapidly declining costs, and increasing demand across the private and public sector for clean electricity, there are now more than 155 gigawatts (GW) of solar capacity installed nationwide(SEIA, 2023 enou h toFigure 1 - Annual U.S. Solar PV Installations and p Y )� g power more than 18% of homes in the United States (Banmiller, 2023). Solar photovoltaics have represented the largest share of new generating capacity across all sources for each of the last four years. In the first half of 2023, 45% of all new capacity added to the grid came from solar (SEIA, 2023). As Figure 1 shows, the industry has continued to add increasing numbers of photovoltaic (PV) systems to the grid over the past decade. The notable surge in 2016 was due to a rush to complete as many projects as possible before an expected expiration of the Investment Tax Credit, which pulled projects from 2017 and 2018. The slight decrease in 2022 was due to pricing and procurement challenges, but the industry was anticipating a strong rebound in 2023, and an impressive deployment in the first half of the year puts the industry on track (SEIA, 2023) to meet these expectations. The installation cost of solar energy has witnessed a notable reduction of over 40% in the last ten years, as illustrated in Figure 2, and this decline has facilitated the solar industry's expansion into emerging markets. The primary catalyst for cost reduction has been advancements in technology and Forecasts By Segment, 2014-2028 Source: Solar Energy Industries Association, Solar Market Insight Report 2023 Q3 Figure 2 - U.S. Solar PV Pricing Trends & Deployment Growth Source: Solar Energy Industries Association, Solar Industry Research Data PAGE 02 subsequent price drops in solar equipment. However, the solar industry experienced a modest price increase in recent years due to shipping constraints and supply chain challenges stemming from the Covid 19 pandemic and trading uncertainties. Encouragingly, signs of supply chain stabilization are emerging. Importers are increasingly able to furnish documentation demonstrating compliance with the Uyghur Forced Labor Prevention Act and the Federal Government's moratorium on solar tariffs have led to a greater number of solar modules successfully entering the U.S. market, resulting in the stabilization of price increases in 2023. Utility -scale prices currently range from $16-$35/MWh, which is competitive to other forms of energy generation (SEIA, 2023). B. Colorado Solar PV Industry According to SEIA, Colorado is ranked 12th in the U.S. for total installed solar capacity, up from 25th in 2022. Installed solar capacity is the maximum amount of electricity that generating stations can produce under specific conditions, and it is typically calculated in megawatts (MW). Colorado installed 166 MW in 2022, bringing its cumulative capacity to 2,995 MW, or enough to power 589,898 homes. As seen in Figure 3, the State of Colorado receives a similar amount of irradiance as California, Wyoming, and Utah. Colorado ranks behind only California amongst those peers when it comes to installed solar capacity — California ranks 1st, Utah ranks 13th and Wyoming ranks 44th (Colorado Solar, 2023). Figure 3 VOrtyWitt 730 G%*; Source: Solargis Resource Maps and GIS Data Global Horizontal Irradiation Map of the U.S. 43 3 2 16 SO Maire 7gi<b, t'°.). `•139 2045 2794 With over 300 sunny days per year, Colorado has tremendous solar potential. It was one of the first states in the U.S. to have a Renewable Energy Standard, and there are multiple solar programs in Colorado for rooftop solar, community solar and utility -scale solar. Examples of utility scale solar installations in the State include: the 300 MW Bighorn Solar facility in Pueblo came online in 2021; the 150 MW Comanche Solar facility in Pueblo was completed in 2016; and Amazon's 6 MW DEN3 project in Aurora as one of the largest corporate projects in the State. There are more than 399 solar companies in Colorado including 40 manufacturers, 189 installers/developers, and 170 others. Figure 4 shows the locations of solar companies in the state as of the time of this report. Currently, there are 7,626 solar jobs in Colorado, ranking 7th in the nation (SEIA, 2023). Some of these are located in Weld County.

General Economic Benefits of Utility -Scale Solar PV Energy The U.S. Department of Energy sponsors the U.S. Energy and Employment Report on an annual basis. The Electric Power Generation sector encompasses both utility and non -utility employment within various electric generating technologies such as fossil fuels, nuclear, and renewable energy technologies. This sector is comprised of professionals involved in facility construction, equipment manufacturing, operations and maintenance, as well as wholesale parts distribution for all electric generation technologies. As depicted in Figure 6, in 2023 the solar energy industry boasts the highest employment numbers (8,473), surpassing wind electric generation (7,741) and the collective employment in all other electric generation types (summing to 7,189) (U.S. Energy and Employment Report, 2023). Figure 6 - Electric Generation Employment by Technology 80473 7341 . o . goi t it" e E , .,, 5.1 955 922 29179 263 11� 2 2,758 ttli is It PVC\ CI 6, CFI 1 9 'reliN V C ci% le Source: US Energy and Employment Report 2023: Colorado PAGE 04 Utility -scale solar -powered electric generation facilities contribute many positive economic impacts. During both the short- term construction phase and the long-term operational phase, solar PV installations generate employment opportunities in the community. This includes not only those directly engaged in construction and maintenance, but indirect roles supported through supply chain purchases and induced growth through spending by the workforce. Examples include construction and trades work across the site from grading to structural and electrical installations, as well as local building materials like gravel and concrete. Supporting industries in logistics and other professional services are likely sourced locally. Moreover, solar PV projects contribute to fortifying the local tax base through induced sales tax revenue and property taxes, leading to enhancements in county services and local infrastructure, such as public roads. Many studies have meticulously assessed the socioeconomic benefits of solar PV projects across the United States and are predicting the future impacts of these projects. Tabassum et al. (2021) underscored the critical role of social development in sustainable development, especially considering the unemployment challenges resulting from the Covid 19 pandemic. In this context, the solar market stands out. It has exhibited remarkable job growth from 2016 to 2021, outpacing the overall U.S. economy's job growth by a factor of five, amounting to a 44% increase. Over the decade from 2009 to 2019, major technology corporations such as Apple, Amazon, Walmart, and Google contracted extensive amounts of solar energy for their operations, making up material portions of their energy mix (39,830%, 36,900%, 2,316%, and 12,810%, respectively) and creating many job opportunities in parallel. Notably, the solar industry features a diverse workforce, with veterans comprising 8% of solar jobs - a higher proportion than in any other sector of the economy - and with women constituting 26%. In addition to the creation of new employment opportunities, solar energy facilitates the provision of electricity to remote rural areas and mountainous regions where the construction of traditional power stations may not be practical. The benefits of solar adoption extend to lowering electricity costs by fostering competition in the electricity market, reducing dependence on centralized utilities, and enabling local generation, thereby mitigating transmission and distribution costs. PAGE 05 S _ III. PROJECT OVERVIEW AND IMPACT ON INDUSTRIES AND RESOURCES IN WELD COUNTY A. Project Snapshot The proposed Project consists of an approximately 279 MW AC solar- photovoltaic installation. As proposed, the Project has two Points of Interconnection (POls). The total site spans approximately 2,200 acres. The Project area is bounded by County Road 67 to the east, County Road 73 to the west, County Road 2 to the south, and County Road 8 to the north. State Route 79/County Road 69/Kiowa-Bennett Road and County Road 73 transect the Project Site in north/south direction. The Project Site is on private land. Land ownership surrounding the Project Site is private with one adjacent parcel owned by the State. Approximately eight residential properties lie within 0.5 miles of the Project boundary. The communities within Weld County that are nearest to the Project Site are Sloan, Roggen, Tampa, and Keenesburg, which have roughly 2,000 residents in total. Two communities in other counties are also nearby - Bennett (located across Arapahoe and Adams Counties) and Strasburg (located in Adams County), which have roughly 6,300 residents in total. A variety of natural, land use, and other constraints were considered and avoided in the development and selection of proposed routes and sites for the Project. These included residential, commercial, industrial, and agricultural uses as well as a variety of natural resource considerations, such as sensitive species, Oil and Gas, and Water. B. Weld County, Colorado Economic Snapshot Weld County is in the northeast part of Colorado (see Figure 7). It has a total area of 4,017 square miles and the U.S. Census estimates that the 2022 population was 350,176 with 128,987 housing units. The county had a population density of 82.6 (persons per square mile) in 2020 compared to 55.7 for the State of Colorado. Median household income in the county was $80,843 compared to $89,930 for the State of Colorado. Figure 7 - Location of Weld County, Colorado PAGE 06 As shown in Table 1, the largest employer industry in Weld County is "Construction" followed by "Manufacturing," "Retail Trade," "Health Care and Social Assistance," and "Mining, Quarrying, and Oil and Gas Extraction." The data for Table 1 comes from the Upstate Colorado Weld County Workforce Snapshot which uses the Economic Modeling Specialists International (EMSI) Q2 2020 Data Set, the most recent data available. According to the August 2023 YCharts data, the county's unemployment rate is 3.7%, up from 3% a year prior and higher than Colorado's state unemployment rate of 3.1% ("Weld County, CO Unemployment Rate," 2023).

Key County Industry Impacts: Agriculture Summary The proposed Project's impact on the agricultural economy of Weld County are anticipated to be net positive: • Unirrigated land is being proposed for use. • The Project proposal includes re -seeding the site with native plants supportive of pollinators, which will serve to improve yields of nearby agricultural production. • The site will be protected from urban sprawl for the Project life, leaving the option of a return to agricultural production. Details State of Colorado Agriculture In the most recently published Agricultural Census (2017), Colorado was ranked 25th in total value of agricultural products sold. As of 2022, it ranked third nationally for all sheep and lamb products and was second for wool production. Colorado ranked tenth for all cattle and calves and fifth for cattle on feed. It ranked in the top five for the following crops: proso millet (1), silage sorghum (3), non -oil varieties of sunflowers (4), winter wheat (5), barley (5), alfalfa hay (5), and grain sorghum (5) (USDA's National Agricultural Statistics Service, 2022). In 2022, Colorado had 38,800 farms totaling 31.8 million acres in operation, with an average farm size of 820 acres. In the same year, Colorado had 2.6 million cattle, produced 5.3 billion pounds of milk, and yielded an average 121 bushels per acre for grain corn with a total market value of $889 million (State Agricultural Overview, 2022). The average net cash farm income per farm is $29,669 (Agricultural Census, 2017). Weld County Agriculture In 2017, Weld County had 4,062 farms covering 2,098,803 acres, for an average acre size of 517. The total market value of products sold was $2.047 billion, with 83% coming from livestock, poultry, and product sales and 17% coming from crop sales. The average net cash farm income of operations was $97,295 (National Agricultural Statistics Service, 2017). The agriculture sector in Weld County is strong, ranking first in Colorado and eighth in the nation. The number of farms in the County increased by 37.2% between 1997 and 2017, as shown in Figure 12, and the amount of farmland increased by 185,200 acres or 9.7% over the same period, as shown in Figure 13. Both the number of farms and acres decreased between 2007 to 2012, but increased to their highest levels since then. This data is pulled from the USDA Agricultural Census, which is published every five years. The data from the 2022 Agricultural Census is not yet available.

The breakdown is shown in Table 2. Table 2 - Breakdown of Land Cover Class on Site However, according to the Colorado Division of Resources mapping, only 120.58 acres of the Project site had been irrigated in recent years (indicated by the red circle Figure 14). The crop produced on this portion of the site was corn. It is our understanding that irrigation has ceased in advance of this Project, and that no irrigation is planned. The remainder of the site has been unirrigated and thus assumed to be of lower value to the agricultural output of Weld County in its current state. This previously irrigated 120.58 acres account for 0.0057% of the acres used for farming in Weld County. The land will not be irrigated going forward as part of the proposed Project.

This Project will help protect the land for future agricultural use by preventing permanent loss due to industrialization and urbanization. According to the America's Farmland Trust, low -density urban sprawl permanently eliminates 2,000 acres of farmland annually nationwide.

Because up to 90% of the ground on the site may be covered in vegetation, net-biodiversity gains may be realized based on the vegetation selected, erosion will be minimized due to groundcover, and the soil microbiome will be protected. Results would be similar to fallowed parcels under USDAs Conservation Reserve Program enabling a potential productive return to agriculture upon Project decommissioning. Pollinators attracted by the chosen groundcover such as butterflies, bees, birds, and bats support plant reproduction and reinforce resilient ecosystems. Three -fourths of the world's flowering plants and about 35% of the world's food crops depend on pollinators such as butterflies, bees, birds, and bats to reproduce. During decommissioning, soil previously compacted during construction and operations activities, especially outside the vegetated area, will be recovered and restored. D. Key County Industry Impacts: Oil and Gas Summary No negative impacts on the local Oil and Gas economy are anticipated through the proposed project: • No active or demonstrated production is being hindered. • The power generated and supplied by the Project will contribute to overall lower power costs, which would also support operational cost reductions for Oil and Gas sites. Details State of Colorado Oil and Gas Colorado is the fifth -largest crude oil -producing state, contributing nearly 4% to the nation's output. It holds approximately 4% of the country's economically recoverable crude oil reserves. Colorado's significant growth in crude oil production since 2010, increasing nearly fivefold by 2022, can be attributed to the widespread adoption of advanced drilling techniques such as horizontal drilling and hydraulic fracturing technologies. Monthly crude oil production in the State peaked in November 2019 at slightly more than 17 million barrels and declined to about 11 million barrels by February 2021, due to the economic impacts of the pandemic. Crude oil production again increased in 2022 increased by 3% (U.S. Energy Information Administration [EIA], 2022 and 2023). Weld County Oil and Gas About four -fifths of Colorado's crude oil production is based in Weld County, with much coming from the Niobrara Shale formation located in Denver-Julesburg Basin in northeastern Colorado and neighboring states. Weld County's Wattenberg field is among the top 10 U.S. oil and natural gas fields based on proved reserves (U.S. EIA, 2022 and 2023). There are over 17,000 active wells in Weld County, making up more than one-third of all active wells in the state (Oil and Gas Energy Department). Project Impacts According to the State of Colorado Energy and Carbon Management Commission (ECMC) Maps, seven well bore permits have been filed on the site, as shown in Figure 15. In the figure, the red dots mark the well locations and the purple area indicates the Project site. All well bore permits have expired, and no site reported any production to the ECMC. The Project site is not in the most productive area in the county. Many large producing Oil and Gas sites in the County are also grid connected to support their auxiliary loads. Lower cost power from the Project may support the economics of such Oil and Gas operations in other areas. PAGE 1 1 Figure 16 - Well Locations on Project Site Source: ECMC Database E. Key County Resource Impacts: Water This report does not cover the detailed water use and water rights impacted, but rather focuses on the qualitative impact of the Project on the water resources of the site and region. None of the proposed Project site will be irrigated. Limited municipal or off -site water use will occur during the construction phase, the establishment of the ground cover, and even less during operation. Compared to other uses, the proposed Project is anticipated to have a minimal impact: • Agricultural water use is over 100 times that of a solar project per acre (Bracken, et al, 2015; Colorado State University; Penn State Extension. • The establishment period of a solar project (construction, initial startup) is roughly equivalent to residential water use on a per acre basis. • Water use during the Project operation period drops to under 1/40th of the use during the construction and establishment period. Water for construction purposes, such as concrete foundations and dust control, is generally covered via off -site sources by a construction water provider and is appropriately sourced from municipal or private sources. The other anticipated use of water during this Project will be irrigation to establish the selected native vegetation for ground covering. It is expected that the ground covering selected will be suited to the local climate and will not require ongoing irrigation past the establishment period. During the life of the project, the solar PV modules may need to be cleaned to maintain energy output. The exact cleaning schedule is a function of precipitation, dust, and other particulate settling on the panels. To minimize cleaning, the Project intends to treat neighboring roads with GMCO CS products, a blend of liquid magnesium chloride and a complex sugar. The product is an environmentally friendly solution for gravel road stabilization and dust control. This will reduce water consumption related to cleaning during the operation period. Water for operational purposes would either be brought on - site or accessed via an appropriately permitted water source at the site. PAGE 1 2 S _ IV. ENHANCEMENT OF THE SOCIOECONOMIC ENVIRONMENT A. High -Value Job Creation, Earnings, and Economic Output It is anticipated that construction of the Project will have a beneficial impact on the local economies of nearby municipalities and communities. Multiple studies have been conducted to estimate the creation of jobs from solar PV and energy storage projects. Solar PV energy investments create an average of 1.5 times as many jobs as investing the same amount of money in fossil fuels (U.S. EIA, "Levelized Costs", 2022). The Jobs and Economic Development Impact (JEDI) models are widely used screening tools that estimate the economic impacts of constructing and operating power plants, fuel production facilities, and other projects at the local (usually State) level. JEDI estimates the number of jobs and economic impacts to a local area that can reasonably be supported by a power plant, fuel production facility, or other project. Jobs, earnings, and output are distributed across three categories: Project Development and Onsite Labor Impacts (Direct Impacts) The dollars spent on labor from companies engaged in development and on -site construction and operation of power generation and transmission. These results include labor only —no materials. Companies or businesses that fall into this category of results include project developers, environmental and permitting consultants, road builders, concrete -pouring companies, construction companies, tower erection crews, crane operators, and operations and maintenance (O&M) personnel. Local Revenue and Supply Chain Impacts (Indirect Impacts) The increase in demand for goods and services from direct on -site project spending. Businesses and companies included in this category of economic activity include construction material and component suppliers, analysts and attorneys who assess project feasibility and negotiate contract agreements, banks financing the projects, all equipment manufacturers, and manufacturers of replacement and repair parts. Local Revenue Induced Impacts The reinvestment and spending of earnings by direct and indirect beneficiaries. Induced results are often associated with increased business at local restaurants, hotels, and retail establishments, but also include child care providers and any other entity affected by increased economic activity and spending occurring at the first two categories. The total impact of the construction and operation of the Project, as defined by JEDI, is the sum of the above three categories for each construction and for operations. State -specific multipliers and personal spending patterns are used to derive the results. These model defaults are based on interviews with industry experts and project developers. Economic multipliers contained within the model are derived from Minnesota IMPLAN Group's IMPLAN accounting software and State data files. PAGE 1 3 Given the development status of the proposed Project, the default model values have been used. The current planned DC capacity of 380 MW DC is assumed (1.36 DC/AC ratio). As shown in Table 3, most jobs (1,194) are created during the construction period of the project, which may span 12-18 months. Direct construction labor is the largest category. The supply chain impacts on supporting industries are predominantly on the suppliers of building materials for the site, from concrete to fencing. The induced jobs are a result of increased business due to the growth in the workforce in the area. In Table 2 and 3, construction jobs are over the project, construction period of 12-18 months, while operating jobs are on an annual basis. Construction jobs are defined as full-time equivalents (FTE), or 2,080 -hour units of labor (one construction period job equates to one full-time job for 1 year). A part-time or temporary job may be considered one job by other models but would constitute only a fraction of a job according to the JEDI models. Table 3: JEDI Model Job Creation of the PV Portion of the Project within the State A value of "0" indicates no in -State job creation for the respective category. During Construction and Installation Period (12 Annual Jobs [Number of 18 months) Full Time Positions] PROJECT DEVELOPMENT AND ONSITE LABOR IMPACTS Construction and Installation Labor Construction and Installation Related Services Subtotal MODULE AND SUPPLY CHAIN IMPACTS Manufacturing Trade (Wholesale and Retail) Finance, Insurance and Real Estate Professional Services Other Services Other Sectors Subtotal INDUCED IMPACTS TOTAL SHORT-TERM JOB IMPACTS 954.3 240.3 1,194.6 0.0 34.0 0.0 74.5 84.8 285.0 478.4 324.5 1,997.5 During Operating Years (20 Years) Annual Jobs [Number of Full Time Positions] ONSITE LABOR IMPACTS (PV PROJECT ONLY) LOCAL REVENUE AND SUPPLY CHAIN IMPACTS INDUCED IMPACTS TOTAL LONG-TERM JOB IMPACTS 70.5 19.5 12.5 102.5 PAGE 1 4 The construction and ongoing operational work require skilled professionals across trades. Therefore, in addition to the number of jobs, the JEDI model considers the value of the jobs created in the form of earnings. Table 4 shows the earnings impacts from the project, which are categorized by construction impacts and operations impacts. New earnings during construction total over $125 million. New long-term earnings (i.e., over the 20 -year project life) total over $6.3 million.

It is an equivalent measure to the Gross Domestic Product, which measures output on a national basis. As shown in Table 5, the Project generates a net new total economic output of nearly $172 million during construction and an annual net new output of over $8.2 million.

Low Cost and Locally Generated Power According to the U.S. EIA, this Project, like other solar and storage projects, provides lower cost electricity than other generation options. This helps lower power costs for residents and businesses in the Utility service area (U.S. EIA, "Levelized Costs", 2022). Reliable and cheap energy can trigger further economic development in the region. Lower cost power can support utilities in offering more affordable energy to low-income households. Figure 16 shows the comparable cost of energy generation in Colorado, with the yellow solar line notably more economical than Nuclear, Coal, or Natural Gas generation. Figure 16 - Cost of Energy Generation in Colorado Source: SEIA, "Solar and Property Value", 2019 By integrating both Solar and Storage, this Project further supports stable, reliable power generation. Solar and storage projects also contribute to national energy independence and security. Local generation will support power service reliability during extreme weather events such as wildfire that may compromise long distance transmission capacity. C. Increased Income for Landowners Landowners are compensated via lease payments, providing a stable and predictable income. By leasing, the landowner preserves future optionality on using the land for agriculture, other energy development, or other land uses deemed appropriate in the future. D. Minimal Long-term Impact Transportation and Road Use Additional road use outside of the construction period will be negligible. The Project intends to reduce road dust generation by treating the surface of adjacent dirt or gravel roads with GMCO CS products. A local vendor has been identified. PAGE 1 7 E. No Negative Impact on Property Values Various analyses on property value in States across the country have demonstrated that large-scale solar arrays in rural settings have no measurable impact on the value of adjacent properties, and in some cases may even have positive effects. Proximity to solar farms has been proven to not deter the sales of agricultural or residential land (McGa, P. L., 2018). F. Positive Local Health Impacts Based on similar projects in Colorado, the Project could mitigate upward of 450,000 MT CO2 per year and the associated respiratory illness from these harmful emissions. By mitigating these emissions locally, there is a potential positive effect of reduced sick days taken by employees or students, resulting in better productivity and fewer hospitalizations associated with respiratory illnesses and cardiac arrest. These impacts can result in fewer lost wages and lower medical expenditures. Locally, the intent of the Project to treat neighboring roads with a blend of liquid magnesium chloride and a complex sugar will promote local dust control and the associated positive air quality impacts. G. No Negative Visual and Sensory Impacts Visual: The solar field will be constructed at least 500 feet from existing residential buildings or visual screening (e.g., landscaping, opaque fencing, etc.) in line with Weld County's requirements. The facility itself is primarily low height, ranging from 4 feet to 10 feet, reaching a maximum height similar to a field of corn. The visual setting at the Project site is already defined by agriculture of a similar height, combined with high -voltage transmission lines and oil and gas exploration equipment. Thermal: A study from the University of Maryland shows that any heat created by a solar farm is much smaller than what is created by urban areas, dissipates quickly, and can't be measured 100 feet away (SEIA, "Solar and Property Value", 2019). A recent study has demonstrated that large scale Solar facilities have a cooling effect on the land surrounding them (McGa, P. L., 2018). Audible: Sound at the Solar Project will be limited to inverters and the transformers, which cannot be heard past the Project boundaries. H. No Negative Impact on Public and Emergency Services The Project is located within District 3 of the Weld County Sheriff's Department and is within the jurisdiction of the Southeast Weld Fire Protection District. The nearest hospital to the Project Site is the Platte Valley Medical Center in Brighton, CO. None of these services are expected to be negatively affected. PAGE 1 8 V. TAX REVENUE Other projects in Colorado and nationally have reported property tax revenues of $10 to 20 million over the Project's life. Based on the latest information from the State of Colorado, we estimate property tax revenue at $12.99 million over the project life (Table 6). The annualized average is approximately $649,575. This is in addition to the property tax for the land itself (currently $7,239 per year). It is also in addition to tax revenue generated through the local job creation and spending during construction, over the Project lifetime, and at decommissioning through employment and induced spending at local businesses as indicated in Section IV. This calculation is based on the current Mill Levy according to Weld County and the current State assessment rate per the State of Colorado calculation template. Projects over 2 MW in size are assessed at the State -level. Unforeseen interruptions in production or degradation of system performance may affect actual numbers, as well as any changes to the Mill Levy or State of Colorado Assessment Rates.

The property is in southern Weld County near the county line between Weld and Adams Counties, Colorado. The project area encompasses approximately 700 acres of land that is tentatively planned for development as a solar farm. It is situated in the: • SW 1/4 of Section 24 of Township 1 North — Range 63 West • N 1/2 of Section 25 of Township 1 North — Range 63 West • N 1/2 of the SW 1/4 of Section 25 of Township 1 North — Range 63 West • N 1/2 of the SE 1/4 of Section 26 of Township 1 North — Range 63 West • Lot 1 of Section 30 of Township 1 North — Range 62 West • Lot 2 of Section 19 of Township 1 North — Range 62 West The Class I investigation was conducted as part of a due diligence effort by Western EcoSystems Technology, Inc. (WEST) on behalf of project proponents. Should a federal nexus later be identified, the lead federal agency will determine the nature and extent of any additional investigations under Section 106 of the National Historic Preservation Act (NHPA) as amended. The file search and resulting letter report were prepared by Centennial Archaeology LLC (Centennial) for WEST at the request of the project proponent. The Class I file search area includes the Janus Solar property and a 0.5 -mile -wide buffer. This study area intersects all or portions of: • Sections 23-25 and 35-36 of Township 1 North — Range 63 West • Sections 19 and 30 of Township 1 North — Range 62 West File search information was accessed through the Colorado Office of Archaeology and Historic Preservation (OAHP) Compass and General -Purpose Viewer (GPV) web applications; GIS shapefiles of sites and surveys were also obtained. The results of the file search include National Register of Historic Places (NRITP) properties and districts. The GIS shapefiles were obtained on 1 October 5, 2022. Historic maps including General Land Office (GLO) survey plats available through the Bureau of Land Management and USGS topographic maps were also inspected to identify historic trails, transportation routes, and other historic resources that may intersect the study area. Additional sources including materials on file with the Weld County Assessor, Weld County ROW records, historic aerial images, and documents provided by the Colorado Oil & Gas Conservation Commission (COGCC) were similarly reviewed. For this investigation, a minimum age criterion of 45 years was applied when determining if a resource meets the threshold of a historic property. While a 50 -year standard is typically used, 45 years was selected to allow a greater degree of flexibility as the project will almost certainly not be fully permitted by the end of 2022. Historic resources therefore were considered in this file search if they were constructed in or before 1977. OAHP Data Records on file with the OAHP reveal that (Table 1). Inventories were done primarily for road and transmission line projects; however, a survey for a 160 -acre parcel belonging to the Schwindt family was also conducted. Investigations were completed for purposes of compliance with Section 106 of the NHPA. Two of these inventories (WL.E.R12 and MC.E.R80) intersect the southern portion of the project area but much of the footprint remains unsurveyed. conducted within the larger file search area five cultural resource investigations have been Table 1.

These resources include a prehistoric isolated find (IF) of two flakes (SWL.294 1) and a segment of the Hoyt to 2 Terry Street Transmission Line (SWL.2941). Respectively, they were found to be field not eligible for the NRHP and to not support the larger eligibility of the linear resource. Table 2.

Most of these parcels are undeveloped and are used for grazing lands or for agricultural fields. Nine of the properties are coded as containing residences on agricultural lands and/or buildings for agricultural purposes, such as cattle sheds, grain bins, and equipment sheds. Buildings date from 1900 to 2021, with most dating to the early - to -mid 20th century. Based on this information, 18 buildings on six parcels qualify as historic resources. While none of the historic -age buildings directly intersect the project area, it should be noted that some federal agencies require architectural properties to be documented if the parcel intersects the project area even if the parcel is large and the building in question is well outside of the project footprint. Assessor's data also show that one parcel contains a gravel pit. While the Assessor's records do not specify the age of the pit, historic USGS topographic maps and aerial images show that it was created between 1950 and 1957 and therefore meets the age criterion to be considered a historic resource. However, the gravel pit does not directly intersect the project area. Table 3.

The examination of historic USGS topographic quadrangle maps from 1950 through 1978 and Weld County ROW records dating to 1889 and 1937 indicates that county roads, State Highway 79 (SH 79), at least 15 buildings, and a gravel -pit are all situated within the file search area and are historic in age. The 1889 Weld County ROW book shows WCR 73 (Road 570) was established as a section line road in 1911, and WCR 4 (Road 53 6) was operational by 1908. As shown in the 1937 Weld County ROW book, SH 79 (Road 604) was in place by 1914, WCR 6 (Road 669) was established in 1926, WCR 73 (Road 570) was formed in 1911, and WCR 71 (Road S-27) was operational as a minor roadway in 1921. WCR 73 and WCR 71 intersect and parallel the project area, respectively. The 1950 Prospect Valley and South Roggen 1:24,000 -scale USGS topographic quadrangle maps depict several residences and outbuildings along SH 79 and WCR 6, as well as three buildings in the SW 1/4 of the NW 1/4 of Section 25. The 1978 Prospect Valley topographic map shows the abovementioned resources, as well as sand and mud extraction areas along West Sand Creek. The gravel pit and extraction locale with a small network of two -track access roads is shown to the north of WCR 6 on this map. Historic Aerial Images Historic aerial images provided by Historic Aerials' online database confirm the data presented above. An image from 1948 shows all of the roads in the file search area as gravel surfaced at that time. An image from 1957 illustrates the presence of the gravel -extraction pit with associated access roads, several buildings along SH 79 and WCR 6, and a few buildings in the SW 1/4 of the NW 1/4 of Section 25 of Township 1 North — Range 63 West. Minimal -to -no change in the file search area was observed in 1984 and 1993 aerial images (Historic Aerials 2022). COGCC Data A search of the COGCC's online database shows that several oil and gas wells exist within the file search area. While most date to the last 35 years, at least two wells date to the early -to -late 1970s and meet the minimum age criterion for historic resources. However, both 1970s -era wells are positioned outside of the project area. Four oil and gas wells fall within the project area. Two of these wells are in the NW 1/4 of the SW 1/4 of Section 24 of Township 1 North — Range 63 West, 5 and the other two are positioned in the NE 1 of Section 25 of Township 1 North — Range 63 West. The wells date to 1989, 1997, and 2008 and are therefore considered to be modem in age. It should be noted that the file search data mainly reflect prior investigations and public records, and do not necessarily include all cultural resources in the project area. A comprehensive field survey would be necessary to identify the full range of sites.

Introduction Horus Energy (Horus) is currently in the process of preparing permit applications for their proposed Janus and Prospect Solar Projects (Projects) in Weld County, Colorado. As part of the permitting process, Horus has sought to obtain feedback from neighbors within 1,000 feet of the Projects to consider and incorporate neighbor input as appropriate in the permit applications and site plans. This report provides a summary of the July 2023 neighborhood meeting as well as additional individual neighbor meetings that occurred outside of the general meeting. 1 1 Overview The neighborhood meeting for the Projects was held in July 2023 in advance of submitting permit applications to Weld County. Individual meetings were also set up with several landowners upon request. The goal of these meetings was to connect with neighbors about the Projects/ to address the compatibility requirements for Weld County's 1041 permit process, and to gather input from neighbors. 1.2 Project Location The Projects are located in southeast Weld County, along the border between Weld and Adams County. The Projects lie along County Road 79, within Southeast Weld County Fire District, and are located on Agricultural Zoned land. 1.3 Meeting Schedule The neighborhood meeting was held at Weld Central High School on July 5, 2023, from 5:30 to 7:00pm. Individual meetings were held upon request ahead of the neighborhood meeting. 2.

Identify any key opponents that may cause issues with the projects permits. Make the community feel heard and understand the Projects and all Horus Energy is doing with the projects. Connect with local businesses and community members that could be partners in the project, so that Horus can achieve its goal of supporting the local economy. 2.1 Regulatory Requirements Weld County does not require a neighborhood meeting or neighbor input on a proposed project until a public hearing is scheduled following the submittal of a 1041 permit application. The County requires an applicant to notify neighbors within 1,000 feet of a proposed project. Horus strives to be a supporter of the local community and voluntarily chose to hold a neighbor meeting ahead of submitting the permit application in order to proactively include public input into project design. 3 Neighbor Meeting Report Janus and Prospect Solar Projects 2.2 Neighbors/Community Members List Table 2.2-1 presents the list of the neighbors and community members within 1,000 feet of the project boundaries.

This proposed photovoltaic Solar Project is located approximately 12 mites northeast of Denver International Airport, and about 12 miles southeast of the Town of Hudson. It is our understanding that this Solar Project would be at most 670 acres to produce upwards of 80 megawatts of alternating current (MWac), and is currently slated to begin construction in 1Q 2025 with a Commercial Operation Date (COD) by 3Q 2026. CPW also understands that there will be a new collector substation, a switchyard, and approximately 2,000 feet of new above -ground transmission tines to tie to the adjacent existing infrastructure. CPW appreciates that Horus Capital and Western EcoSystems Technologies (WEST) have initiated early consultation with CPW because it can lead to a responsibly -developed project that works toward achieving state solar goals1 white protecting sensitive wildlife species, habitats, and time frames. We recognize renewable energy development is important to meeting the State's greenhouse gas reduction goals and improving our climate resiliency. 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 goal 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 (HPHs)2. 1 https://energyoffice.colorado.gov/climate-energy/ghg-pollution-reduction-roadmap 2 https://cpw.state.co.us/Documents/Conservation-Resources/Energy-Mining/CPiI HPH-Map-Layers.pdf Jeff Davis, 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 Horus Capital's Prospect Solar Project — CPW Comments (5/17/23) Page 2 of 4 HPHs are defined as sensitive wildlife habitats where CPW has sound spatial data3 and scientifically -backed best management practice recommendations to help developers with the siting process to minimize any impacts. RECOMMENDATIONS FOR THIS PROJECT CPW appreciates that this Solar Project is sited entirely outside of mapped HPHs, though this Project is bisected by the north -flowing Sand Creek. Therefore, CPW encourages the following recommendations for this Solar Project to avoid and minimize their impact on this and other likely occurring wildlife species: • Big Game Movement Corridors O Although this Solar Project is outside of any mapped HPHs and Sand Creek has a very minimal riparian corridor, the biggest impact from this Solar Project wilt be the loss of open space and the fragmentation of existing and accessible big game habitats. Therefore, CPW appreciates our recent conversations that focused on incorporating at least one north -south movement corridor along Sand Creek in the final site plans by using creative siting solutions without compromising MWs. Note, 250 feet should be considered the bare minimum width, and the longer the proposed corridor, the wider the corridor should be. ■ Furthermore, corridor entrances should not be 90 -degree angles, but more of an inviting funnel, as shown below in the right image. • Pre -construction Nesting Surveys O Please complete pre -construction nesting bird surveys in the disturbance areas (panels, layout yards, access roads, transmission lines, etc.) for the following species and send us the results prior to construction: ■ Burrowing Owls4 (if prairie dog towns are present) between March 15 to August 31. ■ Tree and ground -nesting raptors5 - if construction begins between December 1 to July 15 (depending on the species observed). ■ Migratory songbirds - if construction begins between April 1 to August 31. 3 https://www.arcgis.com/home/item.html?id=190573c5aba643a0bc053e6f7f0510b7 4 https://cpw.state.co.us/Documents/WildlifeSpecies/LivingWithWildlife/Recommended-Survey-Protocol-Burrowing-Owls.pdf 5 https://cpw.state.co.us/Documents/WildlifeSpecies/LivingWithWildlife/Raptor-Buffer-Guidelines.pdf Horus Capital's Prospect Solar Project — CPW Comments (5/17/23) Page 3 of 4 • Fencing Q Minimize fencing to the maximum extent practicable, and use wildlife -friendly fencing' as much as possible. Q For specific wildlife exclusion fencing specifications around the Solar Project, 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. Q Also, CPW recommends that other non -security fencing in the immediate vicinity is removed to the extent practicable and with landowner consent. Q 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. • General habitat recommendations O Avoid development near mapped streams and wetlands. O Develop a noxious weed management plan prior to construction and regularly implement it so noxious weeds do not spread to adjacent habitats. O Please use CPW's restoration seed mix for mule deer HPH (with landowner permission) (we can email it to you separately if desired). O CPW requests that security lighting is kept to a minimum, and ideally, motion sensor lights are installed. CPW appreciates the opportunity to review this project and provide comments and recommendations to avoid and minimize impacts on wildlife resources.

Through the Conservation Reserve Program, farmers voluntarily e nroll to remove land from agricultural production for a decade or more, allowing the soil to rest, improve water quality, prevent soil erosion, and enhance wildlife habitat. Between 2017-2021 the Conservation Reserve Program contributed $29 million to Weld County farmers who in return installed pollinators, n ative grass plantings, and habitat buffers on 29,090,876 acres of private land (EWG 2023). Similarly, during the life of the Project, long-term resource -conserving perennial grasses and forbs will improve soil fertility and reduce erosion, weeds will be mitigated, fertilizers will be removed to improve water quality, and riparian buffers are enhanced to benefit wildlife. In return, Horus will provide landowners with rental payments and cost -share assistance during the life of the Project. Pile driving solar panel racking into the n ative soil profile with minimal grading allows properties to return to enhanced agricultural productivity following decommissioning — making utility -scale solar one of the only land uses that enhances prime soils and regional agriculture long-term. Water usage is a great concern for Weld County and Horus is committed to protecting Weld County's waterways and supply. The properties involved in this project have no vested water rights. The project has secured sufficient water resources from a private water service provider to supply what will amount to relatively modest water needs for the Project (0.007 -acre feet per acre per year). As compared to many other uses shown in Figure 1, solar requires minimal water for project operation. The Project's water use plan is intended to preserve the agricultural base of the community and allow for a return to full agricultural and other use of water resources once the solar project is decommissioned. For planning purposes, Project water needs can be divided into the following categories: 1. Construction/Dust Control — Some water will be required to implement the dust control plan and related aspects of the construction phrase. This water may be supplied by outside service companies as part of their spray mix system and may not require any contribution of local water from the area. There will also be stormwater controls and related mitigation measures during construction to manage existing surface water flow and maintain water quality, as required by governing regulations. Finally, some water may be needed for initial planting and maintenance of plants used for screening, although species are selected for their minimal ongoing watering requirements. 2. Fire Control — While this Project presents minimal fire risks, Horus has committed to assisting local fire control authorities in ongoing fire control activities by adding a designated water tank for general fire control purposes. This tank will need to be filled periodically through a private water supplier. 3. Panel Washing and Maintenance — On an ongoing basis, the only water supply needed for the Project is for washing and maintaining the solar panels and supporting facilities, in part to maximize energy return. The exact cleaning schedule is a function of precipitation, dust, and other particulate settling on the panels. To minimize cleaning, the Project intends to utilize a commercial contractor to treat neighboring roads with GMCO CS products, a blend of liquid *Data limited to parcels within project boundary. Similar data on Site Plan includes displayed buffer data. Page HORUS ENERGY Janus Solar Project Areas and Activities of State Interest 1041 and USR Permit Application magnesium chloride and a complex sugar. The product is an environmentally friendly solution for gravel road stabilization and dust control. This will reduce water consumption related to cleaning during the operation period. Water needs will be more than adequately met by (1) the occasional purchase or trucking in of outside water where needed, particularly at the construction phrase, and (2) water purchase through a private water supplier. While fire is not a typical concern for PV and BESS systems, the Project's water tank may be utilized by the Southeast Weld Fire District and will provide a key resource for protection against fires in the region, especially in times of drought.

Setbacks and corridors have been established to preserve the natural resources and connect habitats that do occur on site. Through correspondence with U.S. Fish and Wildlife Service and Colorado Parks and Wildlife (CPW), it was confirmed that the Project site will not be a concern for interfering or disturbing potential habitat for listed species and existing species on the property. To mitigate effects on the local wildlife, a 250 to 500 -foot wildlife corridor has been incorporated into the design plan (Prospect Solar). Overall, there are not any expected to be significant effects on wildlife habitat or endangered wildlife species. 91Page Weld County Treasurer Statement of Taxes Due Account Number P1546399 Parcel 147930000001 Legal Description 30 1 62 PIPELINE (JMJ 3-30) Account: P1546399 DCP MIDSTREAM LP ATTN: PROPERTY TAX 5718 WESTHEIMER SUITE 2000 HOUSTON, TX 77057 Year Tax Interest Fees ,s.
