Project Area Habitat Caerus Operating, LLC | Garfield County, Colorado Wheeler Gulch Solar Project VEGETATION MANAGEMENT PLAN 10 4.2. Integrated Noxious Weed Management Integrated Noxious Weed Management is the implementation of multiple noxious weed control measures into a focused noxious weed management approach. Preventing the spread of noxious weeds is the VMP's first priority. Caerus would conduct its construction activities consistent with the objective of minimizing the potential for the introduction and spread of noxious weed species. An integrated noxious weed management strategy would be used to control noxious weeds during construction and operation of the project. Caerus would adhere to the following weed management guidelines. • Noxious weed control would include a combination of mechanical, chemical, and cultural methods. • Remove all excess soil and plant debris from construction equipment before entering the project area to reasonably ensure that noxious weed seeds or plant parts are not introduced. • All erosion control devices, straw, mulch, soils, aggregate, and seed would be noxious weed free or otherwise inherently free of noxious weeds prior to use in the project area. • Seed mixes would be purchased from a county-approved vendor or would otherwise be submitted for lab analysis prior to use on the project. • Minimize ground disturbance during construction. Upon completion of construction, disturbed areas would be reseeded between October 25 and April 30. • Bi-annual (spring and fall) noxious weed surveys and treatment are recommended. • Noxious weed treatment and monitoring would occur in conjunction with revegetation inspections for four years post-construction. Additional seeding and herbicide treatments would occur as needed during annual inspection events. In general, noxious weed management would be consistent with the Colorado Noxious Weed Act, Garfield County standards for reclamation and weed management, and applicable federal regulations. While Caerus is only responsible for treating noxious weeds that occur within the project area, consideration would be given to the threat posed from integrated noxious weed treatment on other sensitive resources, such as special-status species and aquatic features. Furthermore, Caerus would coordinate with landowners to identify any specific restoration measures, avoidances, risk assessment notifications, or other requests. The project area would be inspected and treated (as needed) for noxious weed occurrences during the construction and post-construction phases. If construction begins in the spring or otherwise during the growing season, noxious weed treatment with herbicides prior to the start of construction would help limit the spread of noxious weeds throughout the project area during construction. Caerus would focus on the treatment and control of concentrated populations of noxious weeds located in areas proposed for disturbances. Construction would start in noxious weed-free areas and then move to infested areas to minimize the potential spread of noxious weed seeds and plant parts. Biological means of noxious weed management have not been proposed for use on the project because other integrated noxious weed control measures would be more effective and/or no reliable biological control exists for the specific noxious weed species in the project area. Caerus Operating, LLC | Garfield County, Colorado Wheeler Gulch Solar Project VEGETATION MANAGEMENT PLAN 11 The project would adhere to treatment methods recommended by the Garfield County vegetation manager and outlined within the county’s noxious weed management plan (GCVM 2016). Methods to control noxious weeds in the project area would include an integrated approach using mechanical, chemical, and cultural measures. These three measures are detailed in the following sections and in Table A.1 (Appendix A). Because noxious weed control methods and approved herbicides can change intermittently, the reclamation contractor is encouraged to contact the Garfield County vegetation manager annually to confirm the recommended control methods. The integrated noxious weed management techniques are summarized in Table 3 and discussed further in Section 4.3 through 4.6. Table 3. Integrated Noxious Weed and Vegetation Management Technique Activity Date1 Responsibility Comment 2022 (Construction) Noxious weed inspection / herbicide application Spring and fall Reclamation Contractor • 30 days prior to construction and based upon noxious weed species’ growing season • Fall to control seeding of weeds Post-herbicide application inspection 10 to 14 days after treatment Reclamation Contractor Application of form/report documenting herbicide treatment and efficacy submitted to Garfield County Wash stations During construction Construction Contractor Stations would be located at project site entry and exit points Post-Construction (up to 4 years) Reclamation inspections and noxious weed treatments Spring and fall (up to 4 seasons) Reclamation Contractor Application form/report documenting herbicide treatment and efficacy would be submitted to Garfield County Native Seed Mix application Post-construction (Oct 25 – April 30) Reclamation Contractor May require more than one round of seed application Annual mowing/ mechanical vegetation maintenance June 15 – July 15 Reclamation Contractor Activities would be ongoing for the life of the solar facility 1 The precise application date(s) would be determined by the contractor based upon the target species and other seasonal and environmental conditions. 4.3. Chemical Control It is important to treat small infestations of noxious weeds chemically (List A and B species to be eradicated) as soon as possible. Table A.1 lists which noxious weed species respond best to chemical control. Herbicides are most effective when sprayed at specific stages of a noxious weed species’ lifecycle (GCVM 2016). The application of herbicide to control noxious weeds would occur each year, as needed, in the late spring or early summer. Specific chemical recommendations are available from the Garfield County Vegetation Management (GCVM) Department. All herbicide applications would comply with applicable labels, laws, regulations, and permit stipulations. Furthermore, any use of an herbicide inconsistent with the label can lead to injury of crops, humans, animals, and the environment. Therefore, chemical treatments would be conducted by a licensed herbicide applicator according to individual chemical and label requirements. Caerus Operating, LLC | Garfield County, Colorado Wheeler Gulch Solar Project VEGETATION MANAGEMENT PLAN 12 All herbicides are required to have a Human Health Risk Assessment. Notification of registered pesticide-sensitive persons must be given in accordance with C.R.S 35-10-112, and Part 12 of the Pesticide Applications Act. Applicators are required to notify registered individuals prior to applying herbicides on adjacent properties. For information about the registry, call the Colorado Department of Agriculture (CDA) at 303-239-4146. Furthermore, the reclamation contractor would provide Garfield County a list of proposed herbicides to be used for treatment efforts each year. The herbicide list is subject to change due to current site conditions, efficacy of treatments, availability of new herbicides, and other factors. Recommended herbicides can be found within the Garfield County Noxious Weed Management Plan (GCVM 2016). Chemical application equipment would vary according to the time of year, plant phenology, size of infestation, chemical being applied, non-target species present, and noxious weed cover in the infested area. The equipment chosen would provide the most effective noxious weed control while also reducing unnecessary environmental impacts, such as application outside of infested areas. ATVs and trailered sprayers would be used for most herbicide application. Spot applications would be used preferentially to avoid non-target plants or limit contamination of sensitive resource areas (i.e., wetlands or stream). Digital copies of herbicides, labels, and safety data sheets would be managed by the reclamation contractor and available upon request. Caerus would initiate noxious weed management efforts for high-priority species and concentrated noxious weed occurrences. Treatment efforts would be limited to the property for which Caerus has management responsibility, which consists of the project area, access roads, and other areas used for staging materials or equipment. In addition, Caerus would prepare and submit reports to Garfield County detailing all noxious weed treatments (see Section 5.3). 4.4. Mechanical Control Mechanical control would include mowing, cutting, and hand removal of noxious weeds. Table A.1 lists and details which noxious weed species respond best to mechanical control. The extent of the infestations across the project area would limit the effectiveness of post- construction mechanical control methods to spot control. Also, mechanical control methods used across large areas could increase soil erosion and encourage additional weed species' colonization or spread. However, small infestations (less than 0.5 acre) can be controlled effectively using mechanical control methods. Although not a primary method of noxious weed management, mechanical control would be used when chemical control is ineffective or otherwise prohibited. Mechanical control would be used during the construction process when existing vegetation is removed to permit for the installation of the underground conductor, aboveground conductor panels, and associated design infrastructure. Road base aggregate would be used on the project area interior access roads. Disturbed soils and vegetation would not be removed from the site as a result of access road work (grading and recontouring). Sagebrush vegetation would be mowed, chipped, and spread onsite to create microhabitat and help retain topsoil, encourage the regrowth of existing native vegetation, and promote reclamation of reseeded areas. Prescribed burns and grazing would not be used as a method of mechanical control on the project. Caerus Operating, LLC | Garfield County, Colorado Wheeler Gulch Solar Project VEGETATION MANAGEMENT PLAN 13 4.5. Cultural Control Cultural control methods or management practices are those that favor the growth of desirable plants over noxious weeds, including maintaining optimum fertility and plant moisture status, revegetating at optimum density and spatial arrangement, and planting species most suited to a particular area. Techniques include dense seeding, fertilization, mulching, careful irrigation practices, sensible grazing regimes, and improved land management practices (GCVM 2016). Where possible, the project would limit the establishment of new noxious weed infestations by minimizing disturbance and weed seed dispersal while maintaining the native vegetation community. Disturbances would be revegetated with an approved native seed mix. Using native plants or seeds to revegetate disturbed areas helps to control the degradation of native ecosystems, limit the need for herbicides, and conserve water. Project construction would also avoid disturbances on wetlands and streams, thereby minimizing the potential spread of noxious weed species associated with mesic soils. Table A.1 lists which weed species respond best to cultural control. 4.6. Wash Stations Equipment and vehicle cleaning is an important noxious weed control component of project activities. Mud and soil on equipment and vehicles have the potential to carry weed seeds or propagative plant parts to or from the project area. Implementing the following proactive measures and approaches to noxious weed management would significantly reduce the potential for project activities to spread noxious weed species. • Vehicles would be inspected and washed to remove all mud and soil that could harbor noxious weed parts (i.e., roots, seeds, and vegetation) prior to entering or exiting the project area. • Wash and inspection stations would be located at project area entrance points. • Clean equipment may enter or exit the project area without washing, assuming the equipment has been properly inspected. 5. Monitoring, Reporting, and Remedial Action Monitoring revegetation and noxious weed occurrences in the project area would occur annually for four years post-construction. Surveys would be conducted by qualified personnel at least once a season to ascertain the nature and distribution of existing and new noxious weed occurrences. Noxious weed occurrences would be evaluated using the management guidelines described in Section 4, and appropriate management methods would be implemented to control further spread and encourage the growth of native vegetation. 5.1. Revegetation The reclamation contractor would conduct annual reclamation monitoring, reporting, and remedial action after construction is complete. Annual monitoring and reporting of progress for all reclaimed areas would occur for four years or until the revegetated areas reach 70 percent cover as compared to pre-construction native vegetation. Monitoring would consist of qualitative assessments at sites where revegetation progress and soil stabilization would be compared to adjacent native plant community conditions. Monitoring sites used to prove attainment of Caerus Operating, LLC | Garfield County, Colorado Wheeler Gulch Solar Project VEGETATION MANAGEMENT PLAN 14 reclamation standards would be identified by the reclamation contractor. Reclamation success would be approved by Garfield County when disturbed areas meet the reclamation success criteria listed in Section 3.3. Annual qualitative and quantitative performance monitoring would be conducted by the reclamation contractor to determine reclamation effectiveness and revegetation of reseeded areas. Post-construction monitoring would begin in the growing season in the first year following construction and would occur annually until conditions meet the success criteria. Post- construction monitoring would qualitatively assess the following ecosystem indicators as compared to adjacent native vegetation conditions. • Bare ground percentage, including rocks, woody debris, biotic soils, and leaf litter • Plant cover percentages, vegetation composition, and soil stability • Noxious weed species (new and existing populations) 5.2. Noxious Weeds Management Management and monitoring activities within reclaimed project areas are expected to require ongoing and integrated noxious weed control. Monitoring noxious weed occurrences would primarily involve inspections of previously treated areas but would also inspect other areas to minimize the spread and establishment of noxious weed species. Monitoring would occur 10-14 days after the implementation of noxious weed control measures to determine the efficacy of control methods. As required, additional control measures would be conducted by the reclamation contractor to manage noxious weed occurrences. Guidelines for monitoring and integrated noxious weed management would include the following. • Monitoring would be conducted using a qualitative, visual assessment of the previously implemented noxious weed management control(s) efficacy. • At each detected noxious weed occurrence, surveyors would record species, relative population size, and location (including GPS coordinates). • Additional control measures would be implemented to control existing noxious weed occurrences and minimize their potential to spread into reclaimed project areas. 5.3. Reporting and Remedial Actions The reclamation contractor would submit ongoing noxious weed treatment reports (i.e., herbicide application records) to the Garfield County vegetation manager after each noxious weed treatment event. These reports would include the control method, amount and type of herbicide used (if any), date of application, treated acreage, noxious weed species treated, GPS location of treated area(s), and other pertinent information. Application forms would be submitted within a month of treatment. Other maintenance activities would consist of the installation, replacement, or removal of erosion control measures, as necessary, throughout the maintenance, monitoring, and reporting period. All plastic silt fence, straw wattles, and rock socks would need to be replaced intermittently and removed after reclamation is complete. Plastic becomes litter and a hazard to wildlife even if the item is marketed as "UV degradable." It is therefore recommended that fully Caerus Operating, LLC | Garfield County, Colorado Wheeler Gulch Solar Project VEGETATION MANAGEMENT PLAN 15 biodegradable stormwater control measures are used to avoid the potential hazard to wildlife. All non-biodegradable materials that are not permanent would need to be removed completely before reclamation monitoring is complete. Seasonal precipitation and related runoff could affect overall plant cover within and adjacent to drainage features. With the installation of erosion control devices (e.g., silt fencing, straw wattles) at reclamation sites, seasonal runoff events are not anticipated to reduce the potential to meet the reclamation success criteria. However, if reclamation progress is being affected by runoff and erosion, then remedial actions would be implemented as necessary to address the issue(s). These actions would consist of recontouring, additional erosion control measures, and/or supplementary seeding. Drought conditions caused by low precipitation and prolonged unseasonal temperatures could negatively affect reclamation and revegetation progress. Drought could result in reduced plant regrowth and establishment, higher plant mortality, or an increased potential for noxious weed infestations. Remedial measures for prolonged drought would include strategic reseeding prior to precipitation events; extension of the maintenance, monitoring, and reporting period; and potential adjustment of the performance success criteria for drought conditions. These and additional remedial measures would be implemented by the reclamation contractor and approved by Garfield County vegetation manager (see Table 4). Table 4.

Control Methods for Project Weed Species Species CDA Rank Recommended Control Methods1 Control Methods^ Mechanical Chemical Cultural Salt cedar (Tamarix chinensis) B Yes Yes Yes Mechanical: Methods using a bulldozer, prescribed fire, chainsaws, or loppers must be followed up with chemical treatment. Chemical: Herbicide applied through cut-stump treatment, treatment of resprouts when they are 1 - 2 meters tall, or basal bark treatment. Cultural: Revegetation is necessary after treatment to protect soil and reduce reinvasion threat. Recommended Approach: Integrated management using mechanical and chemical methods. Canada thistle (Cirsium arvense) B Yes Yes Yes Mechanical: Mowing can be effective if done every 10 - 21 days throughout the growing season. Chemical: Treatments may be necessary for 1 - 3 years because of nutrient stores. Cultural: Prevent bare ground and maintain healthy pastures, riparian areas, and rangelands. Recommended Approach: Integrated management using mechanical and chemical methods. Common burdock (Arctium minus) C Yes Yes Yes Mechanical: Hand pull or dig when soil is moist and bag plants immediately. Mowing can also be effective. The goal is to prevent seed production and/or spread. Chemical: Herbicide applied on spring or fall rosettes or young, actively growing, pre-flowering plants. Cultural: Minimize soil disturbances and encourage establishment of desirable grasses and forbs. Recommended Approach: Mechanical, cultural, and chemical control methods. Downy brome (Bromus tectorum) C No Yes Yes Mechanical: Mechanical methods are best for small infestations. Mowing is not recommended as it leaves roots intact, stimulates flower production, disperses seeds, and can expand the size of the infested area. Chemical: Herbicides are effective but are often impractical for larger populations and can affect grasses that would otherwise compete with downy brome. Cultural: Revegetating with a perennial grass promotes natural competition and effective control. Recommended Approach: Integrated management using cultural and chemical control methods. Common reed (Phragmites australis) Watch List Yes Yes Yes Mechanical: Large stands may be reduced in density, biomass, and height through grazing. Mowing and burning early in the growing season reduces biomass and increases the contact area for herbicide applications on new growth. Chemical: Broadcast application early in the growing season or when inflorescences start to form, followed by spot applications in following years. Cultural: Revegetating with native perennials following treatment. Recommended Approach: Mechanical, cultural, and chemical control methods. ^ Annual treatments for four years post-construction 1 Biological controls are not proposed or recommended in the project area.

Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update EXECUTIVE SUMMARY 1 Executive Summary HDR Engineering, Inc. (HDR) has completed a Phase I Environmental Site Assessment Update (Phase I ESAU) of an 88-acre parcel located in Garfield County, Colorado. The parcel is the proposed site for a 10 megawatt (MW) solar energy system referred to as the Wheeler Gulch Solar Project. Caerus Oil and Gas LLC (“User”), current owner of the property for the proposed Wheeler Gulch Solar Project, has requested a Phase I ESA Update for permitting support to develop the Wheeler Gulch Solar Project. A previous Phase I ESA report dated January 27, 2023 (January 2023 Phase I ESA) was prepared by HDR for Caerus Oil and Gas LLC. The previous report included the same footprint as the current Subject Property. This update addresses new Agency information received after the January 2023 Phase I ESA was completed. The property, referenced herein as the “Subject Property,” is an irregularly shaped lot (Parcel Identification Number [PIN] 217133100020). The Subject Property is bound by American Soda LLP, a soda ash manufacturing facility to the southeast and the Parachute Creek Natural Gas Plant to the northwest. Parachute Creek runs through the southern portion of the Subject Property, and County Road 215 runs through the northeast portion. The surrounding property land use consists of industrial facilities, open rangeland, and oil and gas infrastructure. Figures 1 and 2 provide further detail regarding the boundaries of the Subject Property. This Phase I ESAU was conducted and updated in accordance with the scope and limitations of the ASTM Practice E 1527-21. This Phase I ESAU identified one Controlled Recognized Environmental Condition (CREC) in connection with the Subject Property. The Phase I ESAU includes the required updates to the following primary components, as outlined in Section 4.6 of ASTM E 1527-21: 1) landowner interviews, 2) search of environmental databases (federal, tribal, state, and local government), 3) site reconnaissance conducted on June 27, 2023, and 4) declaration by the environmental professional. Required updates to the search for recorded environmental cleanup liens is considered a User requirement and is outside the scope to the Environmental Professional (HDR). Any exceptions to or deletions from ASTM E 1527-21 are described later in this report. Findings General findings of this assessment include the following: • The environmental database search conducted by EDR identified three (3) listings within the Subject Property boundaries and twenty-four (24) listings within the ASTM search buffer (1 mile). o All three listings under the PFAS ECHO database within the Subject Property boundary were inactive crude petroleum and natural gas extraction sites with no compliance violations documented. o A total of twenty-four listings were identified at sixteen locations within the one-mile search buffer.  21 listings under the PFAS ECHO database were identified within approximately 0.25 miles of the Subject Property. All sites were listed as crude petroleum extraction and natural gas extraction sites with no compliance violations documented. Nine out of the 21 sites were listed as actively extracting oil and gas, and the remaining 12 sites were listed as inactive. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update EXECUTIVE SUMMARY 2  UNOCAL CORP (2717 GARFIELD CR 215, MAP ID 1). This property is located 0.46 miles downgradient of the Subject Property. • LTANKS/LUST– Records were found for a release on 5/10/1994. Limited details on the tank contents or capacity were provided. A No Further Action (NFA) letter was issued on 8/18/1994. • UST – One 4,018-gallon diesel underground storage tank (UST) and one 4,018-gallon gasoline UST were reported as permanently closed on 12/31/1993.  UNOCAL SHALE OIL FACILITY (2717 CNTY RD 215, MAP ID 2). This property is located 0.5 miles upgradient of the Subject Property. • CORRACTS – This property was ranked as a medium corrective action (CA) priority facility in 1993. An investigation began in 1995 to due to groundwater contamination at active/inactive holding ponds, presence of oil in sewer water upstream of the API Separator and a need to upgrade the drum storage area. The investigation workplan was approved in 1997, remediation construction began in 2000 were complete as of 4/17/2000. This property was deferred to Resource Conservation and Recovery (RCRA) Subtitle C for storage of benzene and was not listed on the National Priorities List (NPL). • An activity use limitation (AUL), in the form of a Deed Restriction and Notification executed in November 1998, was identified on the site for the parcel where the soil repository containing arsenic contaminated soils is located. The Deed Restriction and Notification limits uses of the repository parcel and requires Colorado Department of Public Health and the Environment (CDPHE) notification before any modification or disturbance to the repository commences. No other environmental lien/AULs were identified by the User. HDR did not conduct any additional environmental lien/AUL searches for the Project Area. • No lease documents or other contractual agreements were identified between the current Landowner and the Leasee(s) for the two oil/gas well pads. A Landowner Questionnaire was completed on August 7, 2023, by Mr. Jason Eckman, the Regulatory and Community Relations Lead for the current landowner, Caerus Oil and Gas LLC. Mr. Eckman stated that the property has been owned by Caerus Oil and Gas LLC for five years. Mr. Eckman stated the prior owners of the Subject Property used it to support oil shale development. He was aware of two producing oil/gas wells owned by Terra Energy Partners in the northwest and southeast portion of the Subject Property and a soil repository parcel containing excavated soil contaminated with arsenic from a holding pond in the northwest portion of the Subject Property. Mr. Eckman stated that the soil repository and two producing oil/gas well pads are excluded from the Wheeler Gulch Solar Project. • HDR conducted the site reconnaissance on June 27, 2023. The site reconnaissance identified no changes in site conditions since the December 2022 reconnaissance was completed. The Subject Property is a primarily vacant, undeveloped parcel with mostly short herbaceous plants and some trees surrounding the location of a former holding pond and near the banks of Parachute Creek. A barbed wire fence was present around the majority of the Subject Property. Agricultural fields were present in the northeast portion of the Subject Property, northeast of Highway 215. A well- maintained access road was present in the south-central area of the Subject Property which led to an unfenced equipment storage yard containing a small shed and conex box, as well as generators, trailers, and other construction equipment. Other small areas of the property appeared to be leased to oil and gas businesses including some buildings on the southeast corner of the property and an access road on the eastern side of the property. A small wildfire was in the mountains to the south of Parachute, Colorado. Opinions HDR has reviewed the stated data sources, which are part of the ASTM E1527-21 assessment protocol. Based upon the review of the data, HDR has developed the following professional opinions: Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update EXECUTIVE SUMMARY 3 • An equipment storage yard is present in the southern portion of the Subject Property. The equipment storage yard contains a small shed and conex box, as well as generators, trailers, and other construction equipment. Petroleum products for the generators may exist on site, but not likely in significant quantities. This site is not considered to be a REC. • A Holding Pond and settling ponds/aeration basins were located on the northeast Subject Property from 1981 to 1993. The holding pond was taken out of service in November 1993 and soils in the bottom of the holding pond were tested and shown to exceed the natural background arsenic levels. Soils exceeding a CDPHE established performance standard of 9.8 mg/kg were excavated and placed in a soil repository parcel created out of the former aeration/settling basins immediately north of the holding pond. The soil repository is subject to a AUL in the form of a November 1998 Deed Restriction and Notification. CDPHE certified closure in a January 24, 2002 memorandum indicating that all work required by the Compliance Order (#95-12-21-01) had been completed. Based on this analysis, the Holding Pond is considered to be a historical recognized environmental condition (HREC). The soil repository parcel, in the footprint of the former aeration/settling ponds, is considered a controlled recognized environmental condition (CREC). • The larger East Holding Pond was present in the 1993 historic aerial and remained on site in 1999, undergoing closure, after the adjacent Holding Pond facility had been closed. A December 14, 2001 Final Clean Closure Report provided a summary of closure activities and soil and wastewater analytical results for the closure of Temporary Basin No. 3 (referred to as the larger East Holding Pond in this Phase I ESAU). The Final Clean Closure Report provided the analytical data to support clean closure namely that all contaminated media and materials above clean closure standards were removed from the Site and disposed of at off-site landfills approved by CDPHE. This included documentation that arsenic soils were below the clean closure standard established in the Closure Plan of 9.8 mg/kg. This value is below the current CDPHE soil screening level for arsenic. CDPHE conducted a site inspection on December 17, 2001 and approved clean closure of Temporary Basin #3 in the January 24, 2002 memorandum. This site is considered a HREC. • Oil and gas production in the northwest and southeast corners of the Subject Property has been present since at least the early 2000s. The lease agreements for the two oil/gas well pads were not available. No information was found regarding historical releases; however, a lack of an agreement between the two parties opens up the User to liability should a release occur. The oil/gas well pads are considered a business environmental risk due to a lack of documented agreement between the User and the leasing party. Conclusions Based upon the above-detailed Findings and Opinions, HDR concludes that a CREC have been identified in association with the Wheeler Gulch Solar Project, as summarized in the Opinions section above. The following statement is required by ASTM E1527-21 as a declaration that RECs were found: HDR has performed a Phase I ESA in conformance with the scope and limitations of ASTM E1527-21 of the proposed Wheeler Gulch Solar Project located at 3477 County Road 215 Parachute, CO 81652. Any exceptions to or deletions from these practices are described in following sections of this report. This report has revealed a CREC in connection with the Subject Property. Recommendations Recommendations included in this report were developed through the investigative procedures described in the Scope of Services, Significant Assumptions, and Limitations sections of this report (See Section 2.3). These findings should be reviewed within the context of the limitations provided in the Limitations section. HDR makes the following recommendations: Recommendation 1 HDR recommends that the Wheeler Gulch Solar Project avoid construction in the location of the arsenic soil repository and the operating oil and gas pads identified in Figure 2. If construction is Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update EXECUTIVE SUMMARY 4 anticipated in the location of the arsenic soil repository, per the Deed Restriction and Notification, the User must notify CDPHE before construction commences. Recommendation 2 HDR recommends that the User complete and maintain lease agreements (or other appropriate legal mechanism) with the operator(s) of the oil and gas pads to determine environmental liability should a release occur due to Leasee operations. Recommendation 3 HDR recommends that the User consider the “shelf life” of Phase I documents in determining risk. ASTM E 1527-21 states that a conforming “Phase I” report is valid for a period of 180 days and may be updated during the 180 days to 1-year timeframe. The report is valid for use in any of the CERCLA defenses ONLY if it is updated within this time frame. If greater than one year passes from the final report date, the Phase I effort would need to be repeated to remain in compliance with ASTM and the “All Appropriate Inquiry” protections.

This ASTM standard defines the following categories of recognized environmental condition (REC): REC: (1) The presence of hazardous substances or petroleum products in, on, or at the Project Area due to a release to the environment; (2) the likely presence of hazardous substances or petroleum products in, on, or at the Project Area due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on, or at the Project Area under conditions that pose a material threat of a future release to the environment. ASTM E 1527-21 defines release as a release of any hazardous substance or petroleum product shall have the same meaning as the definition of “release” in CERCLA 42 U.S.C. § 9601(22)). There are a number of statutory exclusions from the definition of release that may impact the environmental professional’s opinions and conclusions, such as the normal application of fertilizer. Controlled REC (CREC): A recognized environmental condition affecting the Project Area that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations). Additional conditions that are not included under the definitions of a REC, but are defined by ASTM Practice E 1527-21 include: Historical REC (HREC): A previous release of hazardous substances or petroleum products affecting the Project Area that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the Project Area to any controls (for example, activity and use limitations or other property use limitations). A historical recognized environmental condition is not a REC. De minimis: A condition that generally does not present a threat to human health or the environment, and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimis conditions are not RECs, historical RECs nor CRECs. Business Environmental Risk: A risk which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated in this practice. Consideration of business environmental risk issues may involve addressing one or more non-scope considerations. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update INTRODUCTION 6 1.2 Report Users HDR received authorization from Caerus Oil and Gas LLC (User) to conduct an Phase I ESAU of the Subject Property. The Subject Property is the proposed site for the Wheeler Gulch Solar Project (specific project limits are shown in Figures 1 and 2), located in Parachute, Garfield County, Colorado. This Phase I ESAU has been prepared for Caerus Oil and Gas LLC, and only Caerus Oil and Gas LLC has the right to rely on the contents of this Phase I ESAU without written authorization. 1.3 Scope of Services, Significant Assumptions, and Limitations The services provided for this project consisted of the following: • Provide a description of the Subject Property including current land uses (Section 2.2 and 2.3) • Provide a general description of the topography, soils, geology, and groundwater flow direction (Section 2.4) • Review reasonably ascertainable and reviewable regulatory information published by federal, state, local, tribal, health, and/or environmental agencies pertaining to the Subject Property (Section 4.0) • Review historical data sources for the Subject Property, including aerial photographs, topographic maps, fire insurance maps, city directories, and other readily available development data (Section 5.0) • Interview current owner of the Subject Property and interview other persons with knowledge of the development history of the Subject Property (Section 6.0) • Conduct an area reconnaissance and an environmental review—including a visual review of adjoining properties—with a focus on indications of hazardous substances, petroleum products, polychlorinated biphenyls (PCBs), wells, storage tanks, solid waste disposal pits and sumps, and utilities (Section 7.0) • Determine data gaps in the information obtained and comment on their significance in identifying RECs for the Subject Property (Section 8.0) • Prepare a written report of methods, findings, opinions, and conclusions (Section 9.0). The goal of this scope of services is to assist the user in identifying conditions in the project area that may indicate risks regarding hazardous materials storage, disposal, or other impacts. The resulting report may qualify the user for relief from liabilities as one of three “defenses” identified in the 2002 Brownfields Amendments to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 9607 (All Appropriate Inquiry subsections). These three defenses include: The “innocent landowner” defense to potential liabilities under 42 United States Code [U.S.C.] § 9601 The “contiguous project corridor owner” defense pursuant to 42 U.S.C. § 9607q The “bona fide prospective purchaser” defense pursuant to 42 U.S.C. §9607r Federal regulations at (42 U.S.C §9601(35)(A) & (B), §9607(b)(3), §9607(q); and §9607(r)), promulgated by the United States (U.S.) Environmental Protection Agency (EPA), require that liability release be based (in part) on completion of All Appropriate Inquiries (AAI) prior to purchase of a property. Those inquiries are documented by Phase I reports, or Environmental Site Assessments (ESAs). EPA has agreed that the recently developed ASTM guidance (ASTM Practice E 1527-21: 3.2.6) specifies and interprets AAI requirements. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update INTRODUCTION 7 A user is defined by ASTM Practice E1527-21 as the party seeking to use Practice E1527 to complete an ESA of the Subject Property and may include a potential purchaser of land in the Subject Property, a potential tenant of the Subject Property, an owner of land in the Subject Property, a lender, or a project manager. Investigative areas not included in the standard ASTM ESA scope include asbestos, lead-based paint, lead in drinking water, radon or urea formaldehyde, wetland issues, regulatory compliance, cultural and historic resources, industrial hygiene, health and safety, ecological resources, endangered species, and high voltage power lines. Indoor air quality from sources such as mold and asbestos are not included in the ASTM standard, except to the extent that indoor air impacts are caused by releases of hazardous substances into subsurface soil or groundwater (vapor intrusion). The potential for vapor encroachment or intrusion into structures in the Subject Property is considered and identified from onsite or offsite sources based on the experience of the Environmental Professional. The scope of services for ESA projects also does not include the completion of soil borings, the installation of groundwater monitoring wells, or the collection of soil or groundwater samples. State and national policies and standards relevant to vapor intrusion are in flux and subject to change. HDR has made certain assumptions in preparing the scope of this assessment: • Data gathered from public information sources (e.g., libraries or public regulatory agencies) are accurate and reliable. • Site operations reflect site conditions relative to potential releases, and no intentional concealment of environmental conditions or releases has occurred. • Interview information is directly reported as gathered by the assessor and is limited by the accuracy of the interviewee’s recollection and experience. • Published geologic information and site observations made by the environmental professional are used to estimate likely contaminant migration pathways in the subsurface. These estimates by the environmental professional are limited in accuracy and are generally cross-referenced with existing information about similar sites and environmental releases in the area. • Regulatory information is limited to sites identified after the late 1980s, because reliable records were not kept by regulatory agencies prior to that time frame. The findings and conclusions presented in this report are based on the procedures described in ASTM Practice E1527-21, informal discussions with various agencies, a review of the available literature cited in this report, conditions noted at the time of this Phase I ESAU, and HDR’s interpretation of the information obtained as part of this Phase I ESAU. The findings and conclusions are limited to the specific project and properties described in this report, and by the accuracy and completeness of the information provided by others. An ESA cannot entirely eliminate uncertainty regarding the potential for RECs. Conducting this assessment is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with a Subject Property within reasonable limits of time and cost. In conducting its services, HDR used a degree of care and skill ordinarily exercised under similar circumstances by reputable members of its profession practicing in the same locality. This Phase I ESA conforms to the level of documentation required in ASTM Practice E1527-21. However, HDR may omit discussion of certain records, i.e., sources deemed, in HDR’s professional opinion, to be inapplicable, or of limited value, to the specific needs of this client. In accordance with ASTM, however, if the lack of available documentation results in a data gap, this data gap is identified herein, and its significance is discussed. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update SITE DESCRIPTION 8 2.0 Site Description 2.1 Location and Legal Description The property, referenced herein as the Subject Property, is the proposed location for the Wheeler Gulch Solar Project. The Subject Property is an irregularly shaped lot, approximately 88 acres in area, located at the addresses listed in Table 1 below, in the town of Parachute, Garfield County, Colorado. Table 1. Property Identification Numbers PIN Address Land Use Lot Size (acres) Listed Owner 217133100020 3477 County Road 215 Parachute, CO 81652 Agricultural/Rural 88 acres Caerus Operating LLC The Subject Property is bound by American Soda LLP, a sodium carbonate and sodium bicarbonate manufacturer to the southeast and Parachute Creek Natural Gas Plant to the northwest. Parachute Creek runs through the southern portion of the Subject Property, and County Road 215 runs through the northeast portion. Please refer to the Project Location and Project Detail Maps (Figures 1 and 2, respectively) for further details regarding project limits and location. 2.2 Site and Vicinity Characteristics The Subject Property lies within the southern half of Garfield County, in the town of Parachute, Colorado. The surrounding property land use consists of industrial facilities, open rangeland, and oil and gas infrastructure. According to the United States Geological Survey (USGS) 7.5-minute topographic map for Parachute, Colorado, the Subject Property lies within a creek bed and pitches south/southwest towards Parachute Creek. The elevation ranges from 5540 (ft) above mean sea level (amsl) in the northeast corner, to 5370 amsl in the southern portion of the Subject Property. Mountain ranges are located to the northeast and southwest of the Subject Property. 2.3 Description of Structures, Roads, and Other Site Improvements Two (2) high-pressure natural gas pipelines parallel the south side of County Road 215 and run through the northeast corner of the Subject Property. A third high-pressure natural gas pipeline was located 300 feet from the western boundary of the Subject Property (NPMS 2022). American Soda LLP, a soda ash manufacturing facility is located adjacent to the east boundary of the Subject Property. The Parachute Creek Natural Gas Plant is located adjacent to the northwest portion of the Subject Property. Thirteen (13) water wells are present within the Subject Property and are described further in section 2.4.2. Two (2) producing oil/gas wells are located in the northwest and southeast corner of the Subject Property. A soil repository cell containing arsenic contaminated soils from a former holding pond is located in the northwest portion of the Subject Property. An access road is present in the south-central area of the Subject Property leading to an unfenced equipment storage yard. Parachute Creek runs through the southern portion of the Subject Property and joins the Colorado River three miles to the southeast. County Road 215 and Garden Gulch Road run through the northeast corner of the Subject Property. Several transmission and distributions lines traverse the eastern portion of the Subject Property. Abandoned Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update SITE DESCRIPTION 9 power infrastructure is scattered through the western portion of the Subject Property with some active infrastructure along the western edge. 2.4 Area Geology and Hydrogeology 2.4.1 Geology The Subject Property is situated on the western flank of the Colorado Rocky Mountains. The local geology consists of Fluvial Deposits overlain by unconsolidated alluvial materials. The Subject Property lies within a river eroded basin. The surficial geology of the Subject Property consists of deposits from the Wasatch Formation, which are classified as fluvial deposits of claystone, sandstone, and conglomerate covered by unconsolidated gravels and alluviums. Deposits from intermountain lakes and related deposits of marlstone and shale are also present in the area (Tweto 1979). The underlying bedrock is the Wasatch Formation which the Molina and Atwell Gulch Members. Bedrock thickness at the Subject Property is approximately 1500ft (Donnell 1986). Soil at the site (Halaquepts) is classified as a clay loam with a very slow infiltration rate and is considered poorly drained (NCSS 2022). 2.4.2 Groundwater and Well Information According to the Colorado State Geological Survey, the underlying fluvial deposits and Wasatch formation bedrock are not considered major drinking water aquifers in the area. Higher yields are typically found in the deeply buried Mississippian Leadville Limestone. Groundwater elevation data is not available for the Subject Property. However, nearby subsurface investigations indicated that the depth to water is shallow (approximately 40 feet below ground surface) and the groundwater flow direction is estimated to be southeastern toward Parachute Creek. The well search conducted by EDR identified ten monitoring wells depths ranging from 35 to 55 feet and three abandoned monitoring wells within the Subject Property boundaries.

No new listings in addition to those in the EDR database report were found. COLORADO PIPELINE AWARENESS National Pipeline Mapping System (NPMS) A search for gas and oil pipelines within the vicinity of the Subject Property and adjacent properties was conducted. The following information was collected: • Two high-pressure natural gas pipelines are located parallel to the south side of County Road 214, which runs through the northwest corner of the Subject Property. A second high-pressure natural gas pipeline was located 300 feet south of the Subject Property. • One hazardous liquid pipeline was located 500 feet west of the Subject Property. A release of 3.60 BBLs of flammable/toxic fluid occurred on 5/14/2020 as a result of equipment failure. 1.60 BBL were recovered. The area where the release occurred was on a concrete pad, adjacent to the east side of four ASTs, and surrounded by a soil berm. No records of the release flowing outside of the bermed area was reported. UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Cleanups In My Community A search for cleanup sites was conducted for the Subject Property and surrounding properties. No new listings in addition to those in the EDR database report were found. 4.2.2 Agency File Reviews Based on the results of the January 2023 Phase I ESA report, Mr. Jason Eckman, on behalf of the User, Caerus Oil and Gas LLC, submitted a document request to CDPHE to obtain closure documents for the two former holding ponds on the property. On June 21, 2023, CDPHE provided the following closure documents and correspondence memorandums: • Final Clean Closure Report Temporary Basin No. 3 Parachute Creek Shale Oil Facility, Parachute, CO, December 14, 2001. • CDPHE Memorandum entitled “RE: Closure Verification and Certification and Closure Approval of Temporary Basin 3 at the Unocal Parachute Creek Upgrade Facility and Compliance Order #95-12- 21-01 Close-out”, January 24, 2002. The first document, the 2001 Final Clean Closure Report, provided a summary of closure activities and soil and wastewater analytical results for the closure of Temporary Basin No. 3 (referred to as the larger East Holding Pond in this Phase I ESAU). The Final Clean Closure Report provided the analytical data to support clean closure namely that all contaminated media and materials above clean closure standards were removed from the Site and disposed of at off-site landfills approved by CDPHE. This included documentation that arsenic soils were below the clean closure standard established in the Closure Plan of 9.8 mg/kg. This value is below the current CDPHE soil screening level for arsenic. CDPHE conducted a site inspection on December 17, 2001 and approved clean closure of Temporary Basin #3 in the January 24, 2002 memorandum. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update RECORDS REVIEW 17 The January 24, 2002 memorandum also provided concurrence with Unocal’s request to close-out and terminate Compliance Order #95-12-21-01. Specifically, it stated: After reviewing the submitted information and information in our files, we [CDPHE] concur with Unocal’s request and herby close-out and terminate Compliance Order #95-12-21-01. The concurrence to terminate the Compliance Order demonstrates regulatory approval for clean closure of the Former Holding Pond. A complete copy of the two Agency files are included in Appendix A. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update HISTORICAL USE INFORMATION 18 5.0 Historical Use Information The objective of reviewing historical use information is to develop a history of previous land uses at, and in the vicinity of, the Subject Property, and to assess these uses for potential hazardous materials impacts that may affect the Subject Property. HDR reviewed those historical sources that were reasonably ascertainable and likely to provide useful information, as defined by the ASTM standard. A historical review of the Subject Property was conducted and documented in Section 5.0 of the January 2023 Phase I ESA. The review found that the Subject Property had historically been vacant up until the late 1970s/early 1980s when holding ponds used to support adjacent industrial facilities, and gas and oil infrastructure were present within the Subject Property. 5.1 Environmental Liens, AULs, and Additional Information The User indicated that no Environmental Liens were found for the Subject Property. An AUL, in the form of a Deed Restriction and Notification, is present on the Subject Property for the parcel where the soil repository containing arsenic contaminated soils is located. The deed restriction was executed in November 1998 by Unocal, the owner of the real property at the time. The deed restriction provided a brief summary of the construction and closure of Unocal’s Construction Camp Holding Pond in the northwest corner of the Subject Property. The Holding Pond, constructed in 1981, was originally designed for use as a polishing basin for a sewage treatment system but in 1987, Unocal was given permission by CDPHE to store treated process water in the Holding Pond until 1993 when it was taken out of service. Arsenic was present in the holding pond above background and 12,000 cubic yards of soil were excavated and consolidated in an on-site soil repository located in the footprint of the aeration/settling ponds. Refer to Figure 2 for the location of the soil repository and the former Holding Pond. The deed restriction and notice (See Appendix C) limits uses of the repository as follows: “future use of the land contained in the Parcel must not disturb the soil repository controls implemented by Unocal. The controls are the graded and compressed cap and liner. Any future owner of the Parcel must notify CDPHE before any modification or disturbance to the existing control commences” 5.2 Summary of Previous Environmental Investigations HDR previously prepared a Phase I ESA of the Project Area dated January 27, 2023. Caerus Oil and Gas LLC, current owner of the property for the proposed Wheeler Gulch Solar Project, requested a Phase I ESA for permitting support to develop the Wheeler Gulch Solar Project. The Subject Property boundary has not changed since the January 2023 Phase I ESA. The January 2023 Phase I ESA identified a two RECS, one CREC and one business environmental risk described below. • A Holding Pond and settling ponds/aeration basins were located on the northeast Subject Property from 1981 to 1993. The holding pond was taken out of service in November 1993 and soils in the bottom of the holding pond were tested and shown to exceed the natural background arsenic levels. Soils exceeding a CDPHE established performance standard were excavated and placed in a soil repository parcel created out of the former aeration/settling basins immediately north of the holding pond. HDR was unable to locate the Closure Plan and associated regulatory approval documents. The soil repository is subject to a AUL that references the closure documents with CDPHE in the form of a November 1998 Deed Restriction and Notification. Based on this analysis, the soil repository parcel is considered a CREC and the footprint of the former holding pond is considered a REC. • The larger East Holding Pond was present in the 1993 historic aerial and remained on site in 1999, undergoing closure, after the adjacent Holding Pond facility had been closed. HDR was unable to Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update HISTORICAL USE INFORMATION 19 locate documentation to identify the type of liquids managed in the East Holding Pond or any regulatory documentation supporting its closure. The East Holding Pond is considered a REC. • Oil and gas production in the northwest and southeast corners of the Subject Property has been present since at least the early 2000s. The lease agreements for the two oil/gas well pads were not available. No information was found regarding historical releases; however, a lack of an agreement between the two parties opens up the User to liability should a release occur. The oil/gas well pads are considered a business environmental risk due to a lack of documented agreement between the User and the leasing party. A copy of the January 2023 Phase I ESA can be found in Appendix B. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update INTERVIEWS 20 6.0 Interviews 6.1 Landowner Interview A Landowner Questionnaire was completed on August 7, 2023, by Mr. Jason Eckman, the Regulatory and Community Relations Lead for the current landowner, Caerus Operating LLC, who stated that the property has been owned by Caerus Operating LLC for six years. Mr. Eckman stated the prior owners of the Subject Property used it to support oil shale development. He was aware of two producing oil/gas wells owned by Terra Energy Partners in the northwest and southeast portion of the Subject Property and a soil repository containing excavated soil contaminated with arsenic from a holding pond in the northwest portion of the Subject Property. Mr. Eckman stated that the soil repository and two producing oil/gas well pads were excluded from the Wheeler Gulch Solar Project. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update SITE RECONNAISSANCE 21 7.0 Site Reconnaissance Mr. Joe Wilch, Geologist and Hydrogeologist with HDR conducted the site reconnaissance on June 27, 2023. The site reconnaissance activities included a review of the Subject Property and surrounding area. No significant changes were noted within the Subject Property from the site reconnaissance conducted on October 18, 2022, for the January 2023 Phase I ESA. The Subject Property was primarily vacant, undeveloped parcel with mostly herbaceous plants and scrubby grasses, areas of tall grasses and shrubs, and some trees surrounding the location of a former drainage basin and near the banks of Parachute Creek. A barbed wire fence was present around the majority of the Subject Property. Agricultural fields were present in the northeast portion of the Subject Property, northeast of Highway 215. A well-maintained access road was present in the south-central area of the Subject Property which led to an unfenced equipment storage yard containing a small shed and conex box, as well as generators, trailers, and other construction equipment. The surrounding properties were industrial oil and gas businesses to the northwest, southeast, and north. These businesses included large oil and gas processing buildings and equipment, and unpaved storage yards with large amounts of vehicles. Parachute Creek traversed the Subject Property in the westernmost section of the Subject Property. The creek was surrounded by dense vegetation and the water was high in silt content. At the time of the site reconnaissance, a small wildfire was in the mountains to the south of Parachute, Colorado. Photographs were not taken during the June 27, 2023 site reconnaissance, but Mr. Joe Wilch confirmed no changes from the January 2023 Phase I ESA photolog were noted. The January 2023 Phase I ESA photolog is provided in Appendix D. 7.1 Utilities and PCBs High voltage power lines transect the eastern portion of the Subject Property from north to south, crossing over the access road to the equipment yard. Abandoned power infrastructure is scattered through the western portion of the Subject Property with some active infrastructure along the western edge. Several mounted transformers were present on power poles throughout the Subject Property, and one abandoned transformer was present in the northwest corner of the Subject Property. No obvious signs of leaks were noted in association with any of the transformers. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update DATA GAP ANALYSIS 22 8.0 Data Gap Analysis The ASTM E1527-21 standards require a listing of “data gaps,” including data failure, encountered during the investigative process that may affect the validity of the conclusions drawn by the environmental professional. The ASTM E1527-21: 12.7 standard also requires that the environmental professional estimate the relative importance of the data gaps. Generally, gaps in available data are related to the availability of historical data sources for specific sites of concern. The environmental professional uses multiple historical data sources as a method to provide coverage for data gaps. Historical information is collected on a recurring basis, and the passage of time between data sets may or may not constitute a significant gap in data coverage. For this project, no significant data gaps, as defined by ASTM E1527-21, were identified. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update FINDINGS, OPINIONS, AND CONCLUSIONS 23 9.0 Findings, Opinions, and Conclusions HDR has completed a Phase I ESAU of an 88-acre parcel located in Garfield County, Colorado. The parcel is the proposed site for a 10 MW solar energy system referred to as the Wheeler Gulch Solar Project. Caerus Oil and Gas LLC, current owner of the property for the proposed Wheeler Gulch Solar Project, has requested a Phase I ESA Update for permitting support to develop the Wheeler Gulch Solar Project. A previous Phase I ESA report dated January 27, 2023 (January 2023 Phase I ESA) was prepared by HDR for Caerus Oil and Gas LLC. The previous report included the same footprint as the current Subject Property. This update addresses new Agency information received after the January 2023 Phase I ESA was completed. This Phase I ESAU was conducted and updated in accordance with the scope and limitations of the ASTM Practice E 1527-21. This Phase I ESAU identified one CREC in connection with the Subject Property. The Phase I ESAU includes the required updates to the following primary components, as outlined in Section 4.6 of ASTM E 1527-21: 1) landowner interviews, 2) search of environmental databases (federal, tribal, state, and local government), 3) site reconnaissance conducted on June 27, 2023, and 4) declaration by the environmental professional. Required updates to the search for recorded environmental cleanup liens is considered a User requirement and is outside the scope to the Environmental Professional (HDR). Any exceptions to or deletions from ASTM E 1527-21 are described later in this report. 9.1 Findings General findings of this assessment include the following: • The environmental database search conducted by EDR identified three (3) listings within the Subject Property boundaries and twenty-four (24) listings within the ASTM search buffer (1 mile). o All three listings under the PFAS ECHO database within the Subject Property boundary were inactive crude petroleum and natural gas extraction sites with no compliance violations documented. o A total of twenty-four listings were identified at sixteen locations within the one-mile search buffer.  21 listings under the PFAS ECHO database were identified within approximately 0.25 miles of the Subject Property. All sites were listed as crude petroleum extraction and natural gas extraction sites with no compliance violations documented. Nine out of the 21 sites were listed as actively extracting oil and gas, and the remaining 12 sites were listed as inactive.  UNOCAL CORP (2717 GARFIELD CR 215, MAP ID 1). This property is located 0.46 miles downgradient of the Subject Property. • LTANKS/LUST– Records were found for a release on 5/10/1994. Limited details on the tank contents or capacity were provided. A No Further Action (NFA) letter was issued on 8/18/1994. • UST – One 4,018-gallon diesel underground storage tank (UST) and one 4,018-gallon gasoline UST were reported as permanently closed on 12/31/1993. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update FINDINGS, OPINIONS, AND CONCLUSIONS 24  UNOCAL SHALE OIL FACILITY (2717 CNTY RD 215, MAP ID 2). This property is located 0.5 miles upgradient of the Subject Property. • CORRACTS – This property was ranked as a medium corrective action priority facility in 1993. An investigation began in 1995 to due to groundwater contamination at active/inactive holding ponds, presence of oil in sewer water upstream of the API Separator and a need to upgrade the drum storage area. The investigation workplan was approved in 1997, remediation construction began in 2000 were complete as of 4/17/2000. This property was deferred to RRCRA Subtitle C for storage of benzene and was not listed on the NPL. • An AUL, in the form of a Deed Restriction and Notification executed in November 1998, was identified on the site for the parcel where the soil repository containing arsenic contaminated soils is located. The Deed Restriction and Notification limits uses of the repository parcel and requires CDPHE notification before any modification or disturbance to the repository commences. No other environmental lien/AULs were identified by the User. HDR did not conduct any additional environmental lien/AUL searches for the Project Area. • No lease documents or other contractual agreements were identified between the current Landowner and the Leasee(s) for the two oil/gas well pads. A Landowner Questionnaire was completed on August 7, 2023, by Mr. Jason Eckman, the Regulatory and Community Relations Lead for the current landowner, Caerus Oil and Gas LLC. Mr. Eckman stated that the property has been owned by Caerus Oil and Gas LLC for five years. Mr. Eckman stated the prior owners of the Subject Property used it to support oil shale development. He was aware of two producing oil/gas wells owned by Terra Energy Partners in the northwest and southeast portion of the Subject Property and a soil repository parcel containing excavated soil contaminated with arsenic from a holding pond in the northwest portion of the Subject Property. Mr. Eckman stated that the soil repository and two producing oil/gas well pads are excluded from the Wheeler Gulch Solar Project. • HDR conducted the site reconnaissance on June 27, 2023. The site reconnaissance identified no changes in site conditions since the December 2022 reconnaissance was completed. The Subject Property is a primarily vacant, undeveloped parcel with mostly short herbaceous plants and some trees surrounding the location of a former holding pond and near the banks of Parachute Creek. A barbed wire fence was present around the majority of the Subject Property. Agricultural fields were present in the northeast portion of the Subject Property, northeast of Highway 215. A well- maintained access road was present in the south-central area of the Subject Property which led to an unfenced equipment storage yard containing a small shed and conex box, as well as generators, trailers, and other construction equipment. Other small areas of the property appeared to be leased to oil and gas businesses including some buildings on the southeast corner of the property and an access road on the eastern side of the property. A small wildfire was in the mountains to the south of Parachute, Colorado. 9.2 Opinions HDR has reviewed the stated data sources, which are part of the ASTM E1527-21 assessment protocol. Based upon the review of the data, HDR has developed the following professional opinions: • An equipment storage yard is present in the southern portion of the Subject Property. The equipment storage yard contains a small shed and conex box, as well as generators, trailers, and other construction equipment. Petroleum products for the generators may exist on site, but not likely in significant quantities. This site is not considered to be a REC. • A Holding Pond and settling ponds/aeration basins were located on the northeast Subject Property from 1981 to 1993. The holding pond was taken out of service in November 1993 and soils in the bottom of the holding pond were tested and shown to exceed the natural background Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update FINDINGS, OPINIONS, AND CONCLUSIONS 25 arsenic levels. Soils exceeding a CDPHE established performance standard of 9.8 mg/kg were excavated and placed in a soil repository parcel created out of the former aeration/settling basins immediately north of the holding pond. The soil repository is subject to a AUL in the form of a November 1998 Deed Restriction and Notification. CDPHE certified closure in a January 24, 2002 memorandum indicating that all work required by the Compliance Order (#95-12-21-01) had been completed. Based on this analysis, the Holding Pond is considered to be a HREC. The soil repository parcel, in the footprint of the former aeration/settling ponds, is considered a controlled recognized environmental condition CREC. • The larger East Holding Pond was present in the 1993 historic aerial and remained on site in 1999, undergoing closure, after the adjacent Holding Pond facility had been closed. A December 14, 2001 Final Clean Closure Report provided a summary of closure activities and soil and wastewater analytical results for the closure of Temporary Basin No. 3 (referred to as the larger East Holding Pond in this Phase I ESAU). The Final Clean Closure Report provided the analytical data to support clean closure namely that all contaminated media and materials above clean closure standards were removed from the Site and disposed of at off-site landfills approved by CDPHE. This included documentation that arsenic soils were below the clean closure standard established in the Closure Plan of 9.8 mg/kg. This value is below the current CDPHE soil screening level for arsenic. CDPHE conducted a site inspection on December 17, 2001 and approved clean closure of Temporary Basin #3 in the January 24, 2002 memorandum. This site is considered a HREC. • Oil and gas production in the northwest and southeast corners of the Subject Property has been present since at least the early 2000s. The lease agreements for the two oil/gas well pads were not available. No information was found regarding historical releases; however, a lack of an agreement between the two parties opens up the User to liability should a release occur. The oil/gas well pads are considered a business environmental risk due to a lack of documented agreement between the User and the leasing party. 9.3 Conclusions Based upon the above-detailed Findings and Opinions, HDR concludes that a CREC have been identified in association with the Wheeler Gulch Solar Project, as summarized in the Opinions section above. The following statement is required by ASTM E1527-21 as a declaration that RECs were found: HDR has performed a Phase I ESA in conformance with the scope and limitations of ASTM E1527-21 of the proposed Wheeler Gulch Solar Project located at 3477 County Road 215 Parachute, CO 81652. Any exceptions to or deletions from these practices are described in following sections of this report. This report has revealed a CREC in connection with the Subject Property. Wheeler Gulch Solar Project | Phase I Environmental Site Assessment Update RECOMMENDATIONS 26 10.0 Recommendations Recommendations included in this report were developed through the investigative procedures described in the Scope of Services, Significant Assumptions, and Limitations sections of this report (See Section 2.3). These findings should be reviewed within the context of the limitations provided in the Limitations section. HDR makes the following recommendations: Recommendation 1 HDR recommends that the Wheeler Gulch Solar Project avoid construction in the location of the arsenic soil repository and the operating oil and gas pads identified in Figure 2. If construction is anticipated in the location of the arsenic soil repository, per the Deed Restriction and Notification, the User must notify CDPHE before construction commences. Recommendation 2 HDR recommends that the User complete and maintain lease agreements (or other appropriate legal mechanism) with the operator(s) of the oil and gas pads to determine environmental liability should a release occur due to Leasee operations. Recommendation 3 HDR recommends that the User consider the “shelf life” of Phase I documents in determining risk. ASTM E 1527-21 states that a conforming “Phase I” report is valid for a period of 180 days and may be updated during the 180 days to 1-year timeframe. The report is valid for use in any of the CERCLA defenses ONLY if it is updated within this time frame. If greater than one year passes from the final report date, the Phase I effort would need to be repeated to remain in compliance with ASTM and the “All Appropriate Inquiry” protections.

The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

The process for obtaining limits involves the regulated entity (permittee) disclosing releases in a NPDES permit application and the permitting authority (typically the state but sometimes EPA) deciding whether to require monitoring or monitoring with limits. Caveats and Limitations: Less than half of states have required PFAS monitoring for at least one of their permittees and fewer states have established PFAS effluent limits for permittees. New rulemakings have been initiated that may increase the number of facilities monitoring for PFAS in the future.

These nine sites, know commonly as UMTRA sites, were remediated jointly by the State of Colorado and the U.S. Department of Energy during the late 1980’s and early 1990’s. Mill tailings were removed from 8 of the mill sites and relocated in engineered disposal cells. A disposal cell is designed to encapsulate the material, reduce radon emanation, and prevent the movement of water through the material. At one site, Maybell, CO, the tailings were stabilized in-place at the mill site. After remediation of the tailings was completed, the State and DOE began to investigate the residual impacts to groundwater at the mill sites. The groundwater phase of the UMTRA program is on-going.

Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

(Harding ESE) has completed the clean closure activities for Union Oil Company of California's (Unocal) Temporary Basin No. 3, located at the Parachute Creek Upgrade Facility near Parachute, Colorado (Figure l.l). The project objective was to achieve final clean closure of the temporary wastewater storage basin, which was formerly located immediately west of the Upgrade Facility (Figure 1.2). Harding ESE performed the closure activities in accordance with the Colorado Hazardous Waste Management Act (CHWMA) (the State of Colorado's Resource Conservation and Recovery Act [RCRA] equivalent) and Unocal's "Final Temporary Basins Nos. l, 2, and 3 Clean Closure Plan" (Closure Plan). The Closure Plan (dated May 19, 1997) was approved by the Colorado Department of Public Health and Environment (CDPHE) on July 21,1997. Clean closure of Temporary Basins Nos. I and 2 were completed in 1998 and approved in 1999. The closure activities for Temporary Basin No. 3 included: (l) evaporating process wastewater contained in the basin; (2) testing, removing, and disposing of residual salts; (3) removing and disposing of liners; (4) charactenzing subliner soils; (5) backfilling and grading; (6) revegetating the area; and (7) decontaminating ancillary equipment. The closure activities were completed in December 2001. This Clean Closure Report presents a description of the tasks performed during closure of the basin, including a summary of the analytical data from the salts, liner materials, and subJiner soil verification samples. This report concludes with a certification of clean closure for Temporary Basin No. 3. 526741.s 12ltvot ccRl2/1 l/01 1Harding ESE 2.O TASK { - PROCESS WASTEWATER EVAPORATION AND SOLIDIFICATION The first task performed during the closure project was evaporation of approximately 3 million gallons of process wastewater. The wastewater had been previously treated to below characteristic hazardous waste levels and is detailed in Section 2.0 of the "Final Clean Closure Report, Temporary Basins Nos. I and2, Parachute Creek Shale Oil Facility, Parachute, Colorado," dated December 7, 1998. After treatment, Temporary Basin No. 3 contained approximately 24 million gallons of nonhazardous water. Task I involved installing a spray evaporator system in the basin to reduce the volume of water. The system operated through 2000 and reduced the volume of water to be managed during final basin closure to 3 million gallons. At the end of the evaporation phase in May 2001, the overall composition of the non-hazardous water in Temporary Basin No. 3 included approximately 80% sodium sulfate, 8% sodium chloride, 8% magnesium sulfate, and 4o/o various carbonate species. In addition, the water contained small amounts of arsenic and selenium, but at concentrations below the regulatory hazardous characteristic levels in 6CCR 1007-3, section 261.24. Four separate water samples were collected in June 2001 from Temporary Basin No. 3 and submitted to Key Laboratories in Grand Junction for metals analysis. The final laboratory results are presented in Appendix A and are summarized below for arsenic and selenium. All samples were below the TCLP limits and confirmed that the water was non-hazardous. An additional water sample was collected from the sump on October I I , 2001 , at the end of the mechanical evaporation task. That sample (Pond #3) had an arsenic concentration of 0.78 mg/l, also below the TCLP regulatory limit. 526't4 1.5 12/1vot ccRl2/l l/01 2Harding ESE Task I - Process }Yastewater Evaporation and Solidification Temporary Basin No.3 Sample Identification Total Arsenic (me/l) Total Selenium (mefl) Pond #1 Pond #2 Pond #3 Evap #l 0.12 0.42 0.44 0.50 <0.1 <0.0001 <0.0001 <0.0001 TCLP limit 5.0 mg/l Arsenic and 1.0 mg/l Selenium mg/l Milligram per liter Unocal began mechanical evaporation of the remaining 3 million gallons of water in June 2001 using two submerged combustion evaporators (SCE). Each SCE unit was operated for 10-12 hours each in a 24-hour shift. In addition, a thermal pump evaporator was also occasionally operated in order to enhance the total evaporation rate. Residual brine from the evaporators was then sent to the adjacent solidification cells. Solidification of the residual brine was accomplished in 4 rectangular reinforced concrete cells. The dimensions of these cells were 16 feet long by 6 feet wide by 4.5 feet high. A lime product (Quicklime) was added to the brine in each cell and thoroughly mixed to ensure complete solidification and stabilization for handling and transport. The estimated amount of lime used for solidification was 2,299 tons per cell for a total of 9,196 tons. Samples of the residual salts, Quicklime, and solidified salt were periodically collected and submitted to Key Laboratories in Grand Junction for Toxicity Characteristics Leaching Procedure (TCLP) analysis for arsenic. The final laboratory results are presented in Appendix A and are summarized below.

Eight samples collected from random truckloads of salt removed from the basin were analyzed for TCLP arsenic to confirm it was nonhazardous. As summarized below, and presented in Appendix B, laboratory results indicated that the salts were non-hazardous for arsenic.

Visual inspection of the liners before removal was difficult due to residual salt material remaining in the basin. Possible breaches, in the form of tears, may have occurred during the removal of the liners using heavy equipment. However, after the removal of the liners these breaches were identified by discolored subliner soils. A total of eight samples were collected from the liners, drainage net, and geotechnical fabric: four from the north side of the basin, and four from the south side. The samples were submitted to Key Laboratories for TCLP analysis. Once the samples were accepted, Key Laboratories combined the four materials from each side of the basin into two discrete samples since there was not enough of each material for individual TCLP analysis. Analytical results relating to this task are presented in Appendix C. Results of the laboratory analyses show that the liner materials were nonhazardous at 0.01 milligrams per liter (m/L) for arsenic for both the north side sample and south side sample. These results are consistent with the liner results from the closure of Temporary Basin Nos. I and2. The non-hazardous basin liners were then cut using a blade mounted on a front-loader, folded or rolled into manageable pieces using a front-loader and bobcat, placed directly into long-dump trucks, and then transported to the Unocal oil shale mine to be used as a protective cover of the entombed salt. 52674 1.5 t2/11/01 ccRl2/l l/01 6Harding ESE 5.O TASK 4. GLOSURE SOIL SAMPLING The soil underlying Temporary Basin No. 3 was evaluated for potential areas of contamination after the liners were removed. The constituents of concem and corresponding closure performance standards are shown in Table 5.1. The analytical results of the samples collected from the underlying soil are listed in Table 5.2. This section describes the soil sampling procedures and results for closure verification. 5.1 Soi! Sampling Procedures Harding ESE implemented the sampling program described in Section 5,2.4 of the Closure Plan to evaluate soil conditions beneath the former lined area in the basin. As described in the Closure Plan, the bottom portion of the basin was gridded into a number of "cells," with 12 cells in Temporary Basin No. 3. Each of these cells was further divided into approximately 50-foot sub-cells. The sub-cells were then randomly selected as the verification sample site for the overall cell, as shown in Figure 5.1. Seventeen random, hand-driven, grab samples were collected from the top 6 inches of soil in the basin, and include: o Twelve separate cell samples and one duplicate cell sample r Four "suspect area" samples were collected. The "suspect area" samples were collected at areas corresponding to areas of discolored soil where possible breaches of the liner may have occurred. 5.2 Soil Sampte Analytical Results All soil samples were submitted to Key Laboratories, Inc. (Grand Junction, Colorado) for analysis of arsenic by EPA Method 6020, volatile organic compounds (VOCs) by EPA Method 8260, and semi- volatile organic compounds (SVOCs) by EPA Method 8270. The analytical results are summarizedin Table 5.2 and are presented in Appendix D. As stated in the Closure Plan, soil areas exceeding the closure performance standard for arsenic are to be excavated and disposed of. Three such areas were encountered in Temporary Basin No. 3 that exceeded the closure performance standard; these were sample locations P3C6HS1, P3Cl lHS2, and P3C10HS3. 526741.5 t2fit/01 ccRl2/l l/01 7Harding ESE Task 4 - Glosure Soil Sampling However, the soil would not be considered characteristically hazardous based on the "Twenty-times Rule". The soil surrounding the three areas was excavated (approximately l0 cubic yards per location), and the material was transported to the Unocal oil shale mine and placed with the nonhazardous salt. The areas were re-sampled, samples P3C6HS1+1, P3Cl lHA2+1, P3Cl0HS3+1, and the results were below the closure performance standard for arsenic. As stated in the Closure Plan, soil areas exceeding the closure performance standard for organics were to be removed, treated onsite with biodegradation, and replaced. No exceedances of the organic closure performance standards were found in Temporary Basin No. 3. Analytical results for all soil samples collected in Task 4 are contained in Appendix D. Analytical results for the verification soil samples indicated no exceedances of the closure performance standards for the constituents of concern. Therefore, the basins meet the clean closure requirements and are considered clean closed. 526741.5 t2ltilot ccRl2/l l/01 8Harding ESE i 6.0 TASK 5 - BAGKFILLING AND GRADING Harding ESE backfilled and graded Temporary Basin No. 3 using clean soil from the berms that formerly surrounded the basins, and onsite stockpiles that were created when the basin was originally constructed. The fill material was compacted with equipment used to haul and spread the backfill. The area will be returned to a natural grade after the final grading is completed in January 2002, with a general slope towards the west. 52674 t.5 12ltvot ccRl2/l 1/01 IHarding ESE 7.O TASK 6.
