Parachute, Colorado
Dear Gregg:
The purpose of thls letter is to inform the Colorado Division of Minerals and Geology
(DMG) of the Unocal Oil Company of Callbmia's (dba Unocal) intent to place certain
uraste materials in tre Unocal Parachute Creek Shale Oll Project mine as part of the
RetoruUpgmde dEcommissioning and closure activities atthe Unocalfacility near
Paradrrrte. Colorado. The decommissioning and closure activitiEs ane scheduled for
la6 summer 1999 and 2000. Unocalhas revlened state environmental prograrns and
conesponding regulations that may affed the projec{. This letter describes horv waste
materials willbe managed in aocordance with the applicable regulations and solicG
DMG's comments on our proposed approacfi.
Wasta Materials
The Unocal Paracfiute Creek Shale Oll Project conslsted of a 13,500 ton-perday mine,
a 10,000 barrel-perday abweground Rdort Facility. where oilshale was heated to
recover raw shale oil, and a 10,000 barrel-perday Upgrade Facll3ty where raw shale oil
uras @nvert'Ed lnto syncrude. Dudng the period of operations, a series of surf;ace
impoundmenb at the Upgrade Facilfi received trcaEd nraters fiom process areas.
Procgss waters floued fiom the Upgrade Facility production units through the oily water
sewer lines, the API Separator, and lnto the Active/lnactive Basins. These waters were
then eused to moisturize and cool retorted shale- \Mten watef production exceeded
the amountthat could be reused, tfie waterwa's diverted from the Ac{iva/lnadive
Basins through the Plant Effluent Llft Station to the Holding Pond and the three
Temporary Basins located atthe Upgrade Facility.

Process waters stored in the Unocal Upgrade Facilrty basins from 1991 were
characteristt'cally hazardous due to elevated concerrtrations of arsenlc and benzene
and were regulated by the Hazardous Matedals and Waste Managemefi Division of
CDPHE. Unocalbegan closure of the basins in 1994, and to date, the Astive Basin,
lnactive Basin, Holding Pond, and Temporary. Basin Nos. 1 and 2 have approved clean
dosure ceffications firom CDPHE. As part of closure, Unocaltreated approximately
25 miltion gallons of hazardous wastanrater to reduce the aeenic conoenhations to
nonhazardous levels. Temporary Basin No. 3 is the last basin to be closed and
contains approximately 10 million gallons qf nonhazardous wastewater.
To compleE closure of Temporary Basin No. 3, Unocalwillevaponate the 10 milllon
gallons to approrimately 2.5 million gallons of nonhazardous liquid and treat the water
in a submerged quench evapomtor. Because the vrater is high in total dissolved solids
(IDS), the finalteatnent willyield approximately 2000 tons of a nonhazardous salt
materialthatwlll subscquently be solidffied wtth fly ash or cement klln dusL wttich wlll
increase the amount of materialto about 4000 tonB. Based on bencfi scale tests, fie
saft material is erpested to be nonhazardous. Unocal conducted pllot Esting of
submerged quenc-tr evaporabr systems ln June 19e9. Atthattime, samples of the satt
matErialwere collested fortesting to confirm that lt is indeed nonhazardots, ln
addilion, Unocalwill colleet sampl* of the material when full scale operations begin in
2000 to confirm the characterization of the materials- AnalyticalresuJts of the salt
materialfrom the pilottests and fullscale operation wtll be provlded fur your review.
Unocalwill place the solidified nonhazardous material in an engineered rcpository in the
Unocal Panactrute CreEk Shale Oil Project oil shale minE, as further described beloral.
No hazardous wastes will be placed in the mine-
Repository Design
The repository will be located just inside the rnine in an unused heading orffthe
Conveyor Drlft, as shonn in Figure 1. Access to the area wlll be through the Main
Reftrm Airway and the 106 Drift, as shown in Figure 2- Figure 3 shovrrs a concepfual
isomEtrlc of the rEposibry. ln general, a 1-fostthict sand base wlllbe placed in the
repository and then werlain with a 60 mil HDPE llner or40 mil reirrforaed PP linerthat
will be anchorsd irrto the ribs of thE heading. A z-foot protective layer of sand will be
placed on top of the liner, as shorrn in Figurc 4.
This portion of the mine is dry and no urater is erpec{ed b enbrthe heading.
Nevertheless, the reposltory is deslgned to keep uraterftom entering and mntacting thE
uraste mabrial, and to eliminac migration of liquids from the cell, if any. Therefore,
once the solidified salt material has been placed in the repository, a @ver liner will be
placed over thE materiat and welded to the boftom and vrrall liner as shown in

Figures 5 through 7. The heading wtth the totally-sealed reposltory willthen be bermed
offto dbaltour any later traffic into the area.
Regulatory Compliance
The satt material that will be placed in the repository is a nonhazardous solid uraste
resulting from the final treatment of wasfierreater stored in Ternporary Basin No. 3. As
describEd above, the materialwill not be a characteristic or listed hazardous \i/aste
according to the regulations in 6 CCR 1007{, part 261, and will not be regulated under
the RCRA hazardoue waste regulations. Because the mlne and retort facility are
regulated under the Colorado Division of Minenals and Geology (DMG) Permit
M-78.263UG, the plaoement of the salt material in the mine is also exemptffom the
stab solid waste regulatlons as stated at 6 GCR 1007-2, section 1.4.2. That section
states that facilities for solid raraste disposal are exempt from the solid vnaste permifting
provisions where a person "engaged in mining operations permitted by IDMGI performs
solict waste disposal of mlning or other solid wastes generated by such operations
wifrrin the permitted area for suott operatlons."
No additional permits appear to be necessary for placement of the materials in the
mine. Nonetheless, Unocal notified Ms. Donna Stoner (CDPHE) regarding solid urasb
and Mr. Joe Sctrie{felin (GDPHE){razardous waste, regarding the mine permit, to
confirm that the GDPHE ls in agreemEnt wtth the proPosed approach. A copy of Ms.
Stone/s approrral letter dated June 18, 1999 is atached-
Unocal will schadule contrac'tors to begin construstion of the reposibry later this
summer and begin placement of material in the spring of 2000- This letbr is intended
to inform you of the underground repository as we continue to decommission the
Parachute Creek Shale Oil Shale Facilities and solicit any comments CDPHE may have
with this proposed approaclr. Please call me al97U2E5-7600 exL?22 if yotl have any
questons or wlsh to arrange yoursite vis'tt l'll be orfi of the office July 12-1S.
Sincerely,
Richard L. Brammer

Dear Mr. Squire:
Unocal would like to change the location in the Long Ridge Mine of the approved
depository for the solidified salts recovered an the closure of Temporary Basin#3.
The requested alternative location is within the ore storage gallery toward the
south wall and beyond the draw down cone of any reclaim feeder. Being in a
dead storage area the material would not be disturbed in any future activity if the
mine were restarted. This location is dry and has a floor comprised of twenty feet
thickness of concrete separating the storage area from the lower reclaim feeder
tunnel. This dry, sealed area would preclude the need to contain the stabilized
salts within a wrapping, as was the previous depository configuration.
The materialwould be stacked on the floor; covered with the high-density
polyethylene pond liner and guarded with concrete barriers so as to prevent
future disturbance from any renewed activity.
The bench testing has shown the solidified material to be wellwithin the
parameters of safety as depicted by the Toxic Characteristic Leaching
Procedure. The leaching limits of arsenic from Unocal's testing were 0.3 to 0.4
ppm. are below the RCRA hazardous limits.

Grand Junction, Colorado 81501
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
Dear Mr. Brammer,
On December 17,2001, Kathryn Stewart and Joyce Williams, as hazardous waste inspectors for the
Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management
Division (the Division), performed a closure verification inspection of Temporary Basin 3. At that time,
all closure activities for Temporary Basin 3 had been completed with the exception of revegetation.
Subsequent to the inspection, we have reviewed the Final Clean Closure Report for Temporary Basin 3
dated December 14, 1998. We have also received and reviewed the independent closure certification
from Harding ESE, as well as the closure certification from Unocal for this same basin.
After our inspection and review, which verified that Temporary Basin 3 had been backfilled, and graded,
and review of the aforementioned information submitted by Unocal, we hereby approve the clean
closure of Temporary Basin 3.
In a separate letter from Unocal dated December 12,2007, Unocal requested termination of Compliance
Order #95-12-21-01 and termination of ground water monitoring in the Holding Pond vicinity. In this
letter, Unocal stated that all work required by the Compliance Order has been successfully completed.
After reviewing the submitted information and information in our files, we concur with Unocal's request
and hereby close-out and terminate Compliance Order #95-12-21-01. In addition, we concw with
Unocal that ground water monitoring is no longer required around the soil repository in the vicinity of
the Holding Pond and can be terminated.
2r/l,
This brings to successful conclusion all hazardous waste activities and clean-up at the Unocal Parachute
Creek facilities. It has been a long effort. We very much appreciate your efforts and the efforts of your
staff over the years to accomplish these tasks. We also appreciate the workjng relationship we have
shared with you, your staff, and your contractors. If you have any questions please feel free to call me at
303-692-3356.
Sincerely,
Joe Schieffelin, Unit Leader
Hazardous Waste Compliance Unit

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.
The purpose of this Phase I ESA is to identify Recognized Environmental Conditions (RECs) that may
adversely affect the Subject Property. This Phase I ESA was conducted in accordance with the scope and
limitations of ASTM International (ASTM) Standard Practice E1527-21. This report includes a summary of
the site reconnaissance conducted on October 18, 2022, landowner interview, a review of environmental
databases, and a review of historical data sources. Any exceptions to or deletions from these ASTM
practices are described later in this report.
Findings
General findings of this assessment include the following:
• The Subject Property is situated on the western flank of the Colorado Rocky Mountains within a
river eroded basin. The local geology consists of Fluvial Deposits overlain by unconsolidated
alluvial materials. The surficial geology of the Subject Property consists of deposits from the
Wasatch Formation as well as the presence of deposits from intermountain lakes and related
deposits of marlstone. Bedrock thickness at the Subject Property is approximately 1500 feet and
soil at the site (Halaquepts) is classified as a clay loam with a very slow infiltration rate and is
considered poorly drained.
• 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 computerized environmental database search conducted by EDR identified 13
monitoring wells at depths ranging from 35 to 55 feet within the Subject Property. Three out of
the ten wells were abandoned. Fifty well records were identified within 1-mile.
• The environmental database search conducted by EDR revealed no listings for the Subject
Property and three listings within the ASTM-designated search buffer (up to 1-mile). One orphan
site was also found in the search. The following listings of potential concern were identified within
the search buffer:
o 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.
o 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).
• A review of historical aerials, topographic maps, and other information concluded that the Subject
Property had historically been vacant up the late 1970s, early 1980s when two holding ponds and
associated infrastructure, referred to as the Holding Pond and East Holding Pond, were used to
support adjacent industrial facilities.
o The Holding Pond was constructed in 1983 and closed in 1993. Arsenic contaminated soils
exceeding natural background standards were identified. These soils were excavated and
placed in an on-site repository north of the main holding pond. HDR was unable to locate
the Closure Plan and associated regulatory approval documents.
o The East Holding Pond was present in the 1993 historic aerial and was undergoing closure
in the 1999 historic aerial. HDR was unable to locate documentation to identify the type
of liquids managed in the East Holding Pond or any regulatory documentation supporting
its closure.
• A review of historical aerials and topographic maps identified gas and oil infrastructure have been
present within the Subject Property, in the northwest and southeast corners, beginning in 2006.
• 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 Colorado Department of Public Health and the Environment (CDPHE) notification before
any modification or disturbance to the repository commences.
• 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 December 5, 2022, 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 sated 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 October 18, 2022. 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. Trash was present in the
southwestern edge of the Subject Property including an old automobile, debris from a wooden
structure, and scrap metal. 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.
• 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 parcel with some active infrastructure at the very
western edge.
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
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
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.
Conclusions
Based upon the above-detailed Findings and Opinions, HDR concludes that RECs have not 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 no indications of RECs 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.
Based upon the identification of RECs in the Subject Property, HDR makes the following
recommendations:
Wheeler Gulch Solar Project | Phase I Environmental Site Assessment
EXECUTIVE SUMMARY
4
Recommendation 1
HDR recommends a Phase II evaluation for soils in the footprint of the former Holding Pond and East
Holding Pond focused on areas where disturbance is anticipated. The evaluation will potentially
hazardous waste impacts and inform soil management needs during construction.
Recommendation 2
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 3
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 4
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.

1.0 Introduction
1.1 Purpose
The purpose of this Phase I ESA is to document the evaluation of the Subject Property for indications of
“recognized environmental conditions,” as defined by ASTM International Practice E1527-21. This ASTM
standard defines the following categories of REC:
REC:
(1) The presence of hazardous substances or petroleum products in, on, or at the Subject Property due to
a release to the environment; (2) the likely presence of hazardous substances or petroleum products in,
on, or at the Subject Property 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 Subject Property under conditions that pose
a material threat of a future release to the environment.
ASTM E1527-21 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 Subject Property 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 E1527-21 include:
Historical REC (HREC):
A previous release of hazardous substances or petroleum products affecting the Subject Property 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 Subject Property to any controls (for example, activity and use limitations or other property
use limitations). A historical recognized environmental condition is not a recognized environmental
condition.
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.

1.2 Report Users
HDR received authorization from Caerus Oil and Gas LLC (User) to conduct a Phase I ESA 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 ESA 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 ESA 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 Subject Property 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 CERCLA Section 9607 (All Appropriate Inquiry subsections). These three defenses
include:
1. The “innocent landowner” defense to potential liabilities under 42 United States Code [U.S.C.] § 9601
2. The “contiguous project corridor owner” defense pursuant to 42 U.S.C. § 9607q
3. 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 ESAs. EPA has agreed that the recently developed ASTM guidance
(ASTM Practice E1527-21: 3.2.6) specifies and interprets AAI requirements.
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 ESA, and HDR’s interpretation of the information
obtained as part of this Phase I ESA. 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.

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. Fifty well records were
identified within 1-mile of the Subject Area.

1955
and
1960
EDR The 1955 aerial image is incorrectly shifted south, but there were no significant
changes to the Subject Property or adjacent properties.
1979 EDR The aerial image was not clear enough to observe any notable features or changes
within the Subject Property.
1983 EDR The aerial image is incorrectly shifted north. A holding pond facility was present in the
northern portion of the Subject Property by 1983 which included a main holding pond
and three aeration/settling basins. Four buildings were present southeast of the
Subject Property. Industrial development was present to the southeast.
1993 EDR A large holding pond was present east of the existing holding pond facility in 1993. The
surrounding properties remained in industrial land use.
1999 EDR By 1999, only the large east holding pond was present within the Subject Property.
2006 EDR By 2006, the large east holding pond had been partially filled in. The rectangularly-
shaped soil repository is slightly visible in the west central portion of the Subject
Property in the footprint of the former aeration/settling basins. One oil/gas well pad
was present in the northwest corner and one well pad was present in the southeast
portion of the Subject Property. Industrial and oil and gas infrastructure including
holding ponds, ASTs, oil/gas well pads and warehouses were present adjacent to the
northwest and southeast boundary of the Subject Property by 2006.
2009 EDR By 2009, the well pad adjacent to the north boundary of the Subject Property had
expanded in size. Three ASTs and four generators were clearly visible in the southeast
corner of the Subject Property.
2017 EDR No significant changes within the Subject Property.
2021 Google Earth By 2021, what appears to be machinery and storage containers are stored in the
southern portion of the Subject Property.
5.4 Historical Topographic Maps
Historical topographic maps provide an overview of the area relative to potential previous land uses. HDR
reviewed USGS 7.5-minute historical topographic maps of the Subject Property provided by EDR. The
USGS 7.5-minute series topographic maps were reviewed for Parachute, Red Pinnacle, and Grand Valley
for 1962, and Parachute, Red Pinnacle, Forked Gulch and Circle Dot Gulch for the years 2013, 2016 and
2019. These maps served to augment information that was gathered in the historic aerial photograph
review.
A review of the topographic maps concluded that the Subject Property had historically been vacant up
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.
Copies of the historical topographic maps are included in Appendix B.
5.5 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 (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”
5.6 Summary of Previous Environmental Investigations
The deed restriction and notice discussed in Section 5.5 described an investigation and closure plan for
the former holding pond facility. HDR was unable to locate these reports to summarize the investigations.
HDR was unaware of any other previous environmental investigations on the Subject Property at the time
of this report.

6.0 Interviews
6.1 Landowner Interview
A Landowner Questionnaire was completed on December 5, 2022, 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 five years. Mr. Eckman sated 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.

SITE RECONNAISSANCE
20
7.0 Site Reconnaissance
HDR conducted the site reconnaissance on October 18, 2022. The site reconnaissance activities included
a review of the Subject Property and surrounding area.
The Subject Property was primarily vacant, undeveloped parcel with mostly short 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 northeast of Highway 215.
Minor amounts of discarded trash were also present throughout the Subject Property. Larger pieces of
trash were found in a ditch near the southwestern edge of the Subject Property. These items included: an
old automobile, debris from a wooden structure, and scrap metal.
A well-maintained access road was present in the south-central area of the Subject Property which led to
an unfenced equipment storage yard. The equipment yard contained a small shed and conex box, as well
as generators, trailers, and other construction equipment. Two producing gas wells were present in the
northwest and southeast portions of the Subject Property.
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.
Photographs taken during the site reconnaissance are 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.

DATA GAP ANALYSIS
21
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, the following significant data gaps, as defined by ASTM E1527-21, were identified:
• The former Holding Pond and aeration basin/settling ponds were closed in 1998. The Deed
Restriction and Notification indicated that the Pond closure was completed in accordance with a
CDPHE-approved Closure Plan. HDR was unable to locate the Closure Plan and associated
regulatory approval documents. Without these documents, it cannot be verified that this facility
closure was completed in accordance with the plan, met the soil performance standards
established for the closure, or was approved by CDPHE.
• A second large holding pond was located east of the Holding Pond discussed in the previous bullet.
This East Holding Pond (refer to Figure 2) 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 locate documentation to identify the type of liquids managed in the East Holding
Pond or any regulatory documentation supporting its closure. Without this information, HDR is
unable to determine the potential hazardous materials impacts in this area of the Subject
Property.

FINDINGS, OPINIONS, AND CONCLUSIONS
22
9.0 Findings, Opinions, and Conclusions
HDR has completed a Phase I ESA of an 88-acre parcel located in Garfield County, Colorado, for a proposed
10 MW solar energy system. Caerus Oil and Gas LLC (“User”) has requested a Phase I ESA for permitting
support to develop the Wheeler Gulch Solar Project.
The purpose of this Phase I ESA is to identify Recognized Environmental Conditions (RECs) that may
adversely affect the Subject Property. This Phase I ESA was conducted in accordance with the scope and
limitations of ASTM International (ASTM) Standard Practice E1527-21. This report includes a summary of
the site reconnaissance conducted on October 18, 2022, landowner interview, a review of environmental
databases, and a review of historical data sources. Any exceptions to or deletions from these ASTM
practices are described later in this report.
9.1 Findings
General findings of this assessment include the following:
• The Subject Property is situated on the western flank of the Colorado Rocky Mountains within a
river eroded basin. The local geology consists of Fluvial Deposits overlain by unconsolidated
alluvial materials. The surficial geology of the Subject Property consists of deposits from the
Wasatch Formation as well as the presence of deposits from intermountain lakes and related
deposits of marlstone. Bedrock thickness at the Subject Property is approximately 1500 feet and
soil at the site (Halaquepts) is classified as a clay loam with a very slow infiltration rate and is
considered poorly drained.
• 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 computerized environmental database search conducted by EDR identified 13
monitoring wells at depths ranging from 35 to 55 feet within the Subject Property. Three out of
the ten wells were abandoned. Fifty well records were identified within 1-mile.
• The environmental database search conducted by EDR revealed no listings for the Subject
Property and three listings within the ASTM-designated search buffer (up to 1-mile). One orphan
site was also found in the search. The following listings of potential concern were identified within
the search buffer:
o 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.
o 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).
• A review of historical aerials, topographic maps, and other information concluded that the Subject
Wheeler Gulch Solar Project | Phase I Environmental Site Assessment
FINDINGS, OPINIONS, AND CONCLUSIONS
23
Property had historically been vacant up the late 1970s, early 1980s when two holding ponds and
associated infrastructure, referred to as the Holding Pond and East Holding Pond, were used to
support adjacent industrial facilities.
o The Holding Pond was constructed in 1983 and closed in 1993. Arsenic contaminated soils
exceeding natural background standards were identified. These soils were excavated and
placed in an on-site repository north of the main holding pond. HDR was unable to locate
the Closure Plan and associated regulatory approval documents.
o The East Holding Pond was present in the 1993 historic aerial and was undergoing closure
in the 1999 historic aerial. HDR was unable to locate documentation to identify the type
of liquids managed in the East Holding Pond or any regulatory documentation supporting
its closure.
• A review of historical aerials and topographic maps identified gas and oil infrastructure have been
present within the Subject Property, in the northwest and southeast corners, beginning in 2006.
• 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 Colorado Department of Public Health and the Environment (CDPHE) notification before
any modification or disturbance to the repository commences.
• 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 December 5, 2022, 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 sated 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 October 18, 2022. 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. Trash was present in the
southwestern edge of the Subject Property including an old automobile, debris from a wooden
structure, and scrap metal. 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.
• 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 parcel with some active infrastructure at the very
western edge.
Wheeler Gulch Solar Project | Phase I Environmental Site Assessment
FINDINGS, OPINIONS, AND CONCLUSIONS
24
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
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
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.
9.3 Conclusions
Based upon the above-detailed Findings and Opinions, HDR concludes that RECs have not 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 no indications of RECs in connection with the Subject Property.

RECOMMENDATIONS
25
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.
Based upon the identification of RECs in the Subject Property, HDR makes the following recommendation:
Recommendation 1
HDR recommends a Phase II evaluation for soils in the footprint of the former Holding Pond and East
Holding Pond focused on areas where disturbance is anticipated. The evaluation will potentially
hazardous waste impacts and inform soil management needs during construction.
Recommendation 2
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 3
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 4
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.

SURROUNDING SITES: SEARCH RESULTS
Surrounding sites were identified in the following databases.
Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on
a relative (not an absolute) basis. Relative elevation information between sites of close proximity
should be field verified. Sites with an elevation equal to or higher than the target property have been
differentiated below from sites with an elevation lower than the target property.
Page numbers and map identification numbers refer to the EDR Radius Map report where detailed
data on individual sites can be reviewed.
Sites listed in bold italics are in multiple databases.
Unmappable (orphan) sites are not considered in the foregoing analysis.
