Case Summary:
The applicant, Prospect Solar, LLC, (Prospect) is requesting a 1041 Solar Energy Facility (SEF) Permit,
Prospect is located on a total of (7) properties for a total SEF size of approximately 1,500 acres and is
generally located between County Road 67 and County Road 75 and between County Road 2 and County
Road 6. State Highway 79 travels north/south through the western portion of the SEF. Prospect will
generate about 199 -megawatt AC (MWAC). The infrastructure includes racking equipment, underground
collection lines, a 100 -megawatt AC (MWAC) Battery Energy Storage System (BESS), a step-up
substation, transformer and maintenance facilities, and a 230kV interconnecting transmission line to
connect to a new Tri-State Switching Station (switchyard). Prospect is a utility -scale project and will be
connected to the grid. The BESS will enable electricity to be delivered to the grid at night.
Ground -mounted solar collectors will be less than 10 feet, measured from the highest grade below each
solar panel to the highest extent of the solar panel rotation. The SEF is not within 500 feet of any residence.
During the twenty-four to thirty-six (24 to 36) -month construction period there will be 300-450 workers at
the site. Construction of the Prospect will occur during daylight hours over the twenty-four to thirty-six (24
to 36) -month construction period. Construction will occur between the hours of 6:30 am to 3:30 pm Monday
through Saturday. If construction activities continue past daylight, nighttime lighting would be temporary
and shielded.
A security fence will be constructed around the perimeter of the Project to prevent the public from entering
the area.
The facility is unmanned, and no water or sewage disposal service is proposed. Bottled water and portable
toilets will be provided during construction.
Prospect is south of and adjacent to the Janus Solar Project which is a 700 -acre. Janus is also a 1041 Solar
Energy Facility Project submitted to the County under USR24-0012. There are two parcels that are part of
Prospect and Janus and due to this these two parcels where divided to ensure that there is only one USR
per parcel. Parcel 147930000001 was split from 320 acres to 80 acres + 240 acres with Janus on the 80
acres portion and Prospect on the remaining 240 acres. Additionally, parcel 147725000007 was split from
160 acres to two (2) 80 -acre parcels. Janus is on the northern 80 acres with Prospect on the southern 80
acres. Due to the timing of these splits the new parcel numbers have not yet been generated by the
Assessor so the parcel number reflected in this report are the previous numbers.
A Decommissioning and Reclamation Plan along with a cost estimate was submitted with the application
materials. An Emergency Response Plan (ERP) was also submitted as requested by Weld County Office
of Emergency Management (OEM). The OEM is reviewing the ERP and is requesting revisions.
Upon receipt of the referral agency comments the application immediately responded with
acknowledgements to the Weld County Oil & Gas Energy Department and the Colorado Parks and Wildlife
(CPW) referral agency comments.
DEPARTMENT OF PLANNING SERVICES STAFF RECOMMENDS THAT THIS REQUEST BE
APPROVED BASED ON THE FOLLOWING APPROVAL CRITERIA:
1. The submitted materials are in compliance with the application requirements of Chapter 21 of the Weld
County Code.
2. It is the opinion of the Department of Planning Services' staff that the applicant has shown
compliance with Section 21-7-350. A of the Weld County Code, as follows:
A. Section 21-7-350. C. 1 — The health, welfare and safety of the citizens of the County will be protected
and served.
Prospect Solar, LLC (Prospect) is a 1041 Solar Energy Facility (SEF) on 1,500 -acres. The SEF will
generate about 199 -megawatt AC (MWAC). The infrastructure includes racking equipment,
USR24-0013 I Prospect Solar, LLC
Page 3 of 23
underground collection lines, a 100 -megawatt AC (MWAC) Battery Energy Storage System
(BESS), a step-up substation, transformer and maintenance facilities, and a 230kV interconnecting
transmission line to connect to a new Tri-State Switching Station.
The 1,500 -acres is generally located between County Road 67 and County Road 75 and between
County Road 2 and County Road 6. This is a remote area of the County. There are seven (7)
affected properties that contribute to the 1,500 acres and there is only one built structure, an
equipment building. Apart from the creek beds the topography is generally flat and the 1,500 acres
consist of undeveloped land along with cultivated cropland, including sorghum and winter wheat.
Four (4) letters of support were submitted with the application materials.
The adjacent properties are zoned A (Agricultural) and the land uses include pastures, crops and
rural residences. Per Section 21-2-260 the Department of Planning Services sent notice to the
surrounding property owners with 1,320 feet and the owners and lessees of the mineral estate on
or under the parcels. In total thirty-six (36) owners were notified. The Department of Planning
Services received eleven (11) letters of objection. The letters outline concerns about wildlife and
the environment, the efficacy of the junipers used for screening, decrease in property values,
aesthetics, "solar farm stigma", water runoff, leaching of hazardous materials, chemical spills, toxic
material release, dust, noise and vibration, increase in the traffic noise from State Highway 79 due
to crop removal, increased truck traffic during construction, glint & glare, heat effects (microclimate),
electromagnetic interference, light pollution, conflicts with future land use plans, psychological
effects including stress and anxiety, change in quality of life, lack of fencing, and sustainable
farming.
Public outreach included individual neighbor meetings, a neighbor open house, and a project
website (https://prospectandjanussolar.com/). The neighbor open house meeting was held on July
5, 2023, at Weld Central High School, and hosted landowners, tenants, and neighbors within 1,000
feet of the site, as well as community partners from across the region. Eight (8) Surrounding
Property Owners attended and discussed their concerns with the application and the applicant met
with a ninth (9th) Surrounding Property Owner one-on-one at a later date. The goal for the meeting
was to share information with and hear feedback from neighbors and local community, so that these
concerns could be factored into how Prospect proceeds forward. Follow up notifications regarding
the project were sent in August to ensure that all neighbors had a chance to review the project and
have their concerns addressed prior to application submittal. The submittal to the County includes
mitigation action for aesthetics (visual), wildlife, soils (erosion), dust, noise, and wetlands and
waterways. Section E outlines some of these mitigation measures.
The Design Standards (Section 23-2-240), Operation Standards (Section 23-2-250), Conditions of
Approval, and Development Standards ensure that there are adequate provisions for the protection
of health, safety, and welfare of the inhabitants of the neighborhood and County.
B. Section 21-7-350.C.2 -- The natural and socio-economic environment of the County will be
protected and enhanced.
The Socioeconomic Impact and Community Benefit Report (Report) provided with the application
materials states that the positive socioeconomic impacts include employment opportunities during the
short term (construction phase) as well as the long-term (operational phase). These opportunities consist
of direct construction and maintenance jobs in addition to indirect effects such as supply chain
purchases, construction in the form of grading, structural, and electrical installations, as well as local
building materials like gravel and concrete which support industries in logistics and other professional
services that are likely sourced locally. Solar projects contribute to fortifying the local tax base through
induced sales tax revenue and property taxes. The solar market has exhibited job growth from 2016 to
2021, outpacing the overall U.S. economy's job growth by a factor of five, amounting to a 44%
increase. Over the decade from 2009 to 2019, major technology corporations contracted extensive
amounts of solar energy for their operations and creating job opportunities. The solar industry
features a diverse workforce.
USR24-0013 I Prospect Solar, LLC
Page 4of23
The Report also states it is estimated that the Prospect Solar Project, in combination with the Janus
Solar Project, will support 1,977 full-time equivalent, direct and indirect jobs, and produce nearly
$13 million in projected property tax revenue. Economic output during the twenty-four to thirty-six
(24 to 36) -month construction phase is estimated to be $171,955,000 and $8,229,700 during the
operating life of the Janus and Prospect Solar Projects.
During the construction period, the local economy may see a small influx of dollars and a small
increase in sales tax revenue. Additionally, the local economy will be stimulated through
employment of Weld County's workforce. For example, the non -local workers will use local hotels,
motels, and other temporary housing, eat at local restaurants, and shop at local businesses.
C. Section 21-7-350.C.3 -- All reasonable alternatives to the proposed action, including use of existing
rights -of -way and joint use of rights -of -way wherever uses are compatible, have been adequately
presented.
Prospect is located on 1,500 -acres generally located between County Road 67 and County Road
75 and between County Road 2 and County Road 6. According to the application materials a larger
land area was initially studied, and the 1,500 -acre final footprint was selected because it offered
advantages to the community and overall environment while providing opportunities and
circumstances favorable to Solar and BESS facilities, specifically:
1) Ample undeveloped flat land, with the ability to accommodate various layouts of PV solar
and the incorporation of appropriate setbacks.
2) Existing transmission infrastructure less than 0.2 miles from the property.
3) Augmenting, while sustaining for future landowners, current unsustainable primary land
use as indicated by the landowners.
D. Section 21-7-350.C.4 -- The proposed action is compatible with and represents the best interests
of the people of the County and represents a fair and reasonable utilization of resources in the
impact area.
The applicant submitted an Environmental Conservation Measures report with the application
materials incorporating the comments of the Colorado Parks and Wildlife (CPW) and the U.S. Fish
and Wildlife and it states, in part, that the final layout of the solar arrays will avoid wetlands,
waterways, and sensitive species habitats.
Additionally, the application materials include an email, dated February 3, 2023, from U.S. Fish and
Wildlife Service (Service) that states that, "...the Service has reviewed your Prospect solar project
in Weld County and has no concerns with this project resulting in impacts to species listed as
proposed, threatened, or endangered. We appreciate your efforts to ensure the conservation of
threatened and endangered species." A letter dated May 17, 2023, from Colorado Parks and
Wildlife (CPW), was also submitted with the application materials and includes information about
incorporating one or more north -south movement corridors for game, recommendations for
conducting pre -construction nesting surveys, and requirements on fencing types. The CPW also
submitted referral agency comments dated June 18, 2024 re -iterating the same information.
The US Department of Energy, the Environmental Protection Agency, the US Fish and Wildlife
Service and the US Army Corps of Engineers did not submit a referral agency response.
Weld County Oil & Gas Energy Department (OGED) submitted referral agency comments dated
June 18, 2024 indicating that there are no 1041 WOGLA Permits on the subject properties but there
are several oil and gas encumbrances near the subject properties.
The Southeast Weld Conservation District's referral dated August 13, 2024 include
recommendations that the applicant conserve natural resources through the implementation of a
revegetation and soil conservation plan, including, but not limited to, pre -planting grass seed,

The application materials state that utilization of local resources within Weld County will be minimal
as Prospect will not require services such as water, sewage, or emergency services at a level
typical of other land uses in the area. The Socioeconomic Impact and Community Benefit Report
submitted with the application materials state that Prospect will be a low water -use development
and that none of the proposed site will be irrigated. However, the applicant is proposing screening
is the form of Rocky Mountain Juniper trees which require, 15,125 gallons of water per week during
the first year of establishment, noting that the trees do not need to be watered during the winter.
Water for construction purposes, such as concrete foundations and dust control, is generally
covered via off -site sources by a construction water provider and is appropriately sourced from
municipal or private sources.
Finally, water will be required to clean the solar panels to maintain energy output. The exact
cleaning schedule is a function of precipitation, dust, and other particulate settling on the panels.
To minimize cleaning, the neighboring roads will be treated with GMCO CS products, a blend of
liquid magnesium chloride and a complex sugar. The product is for gravel road stabilization and
dust control. This GMCO CS reduce water consumption related to cleaning during the operation
period. Water for operational purposes would either be brought onsite or accessed via an
appropriately permitted water source at the site.
The State of Colorado Division of Water Resources in their referral agency comments dated July
3, 2024 stated that a copy of well permit no. 322682 was included in the referral material. This
permit was approved pursuant to CRS 37-90-105 for a well on a tract of land of 160 acres described
as the SW1/4 of Section 24, Township 1 North, Section 63 West of the Sixth P.M., Weld County.
Water from this well may be used for domestic purposes inside two (2) single family dwellings, and
the watering of four (4) of the owner's own large non-commercial domestic animals (per single
family dwelling), irrigation of 2,000 square -feet of lawn and garden and the watering of livestock on
range and pasture. As permitted, this well cannot be used for the proposed solar facility, unless the
well is re -permitted to operate pursuant to a Determination of Water Rights and a Replacement
Plan to be approved by the Groundwater Commission.
Prospect contacted the Division of Water Resources (DWR) to discuss the status of the well.
Prospect is proposing to submit the appropriate documentation to the DWR to re -permit the well,
USR24-0013 I Prospect Solar, LLC
Page 6 of 23
however, in the meantime, Mr. Madole (the current owner of the well) will continue to utilize the well
for its current purposes. There is a Condition of Approval that this well be re -permitted for use by
the fire district prior to recording the map.
The well will be used to fill the onsite water tank for panel cleaning and fire suppression. Prospect
provided the Fire District with the project layout and water tank specs on July 14, 2023 and Oct 11,
2023. The Southeast Weld Fire Protection District provided referral comments dated June 11, 2024,
stating that the applicant is required to go through the District's process of plan review/fees and
inspections prior to construction.
Sewage is not required on the site and portable toilets will be provided during construction.
E. Section 21-7-350.C.5 -- A satisfactory program to mitigate and minimize adverse impacts has been
presented, including decommissioning and reclamation.
The 1,500 -acres that comprise Prospect are located in a remote area of the County. There are
twenty-eight (28) parcels within one -quarter (1/4) mile of the site, ten (10) of these parcels contain
at least one residence. These residences are primarily located west of County Road 71, with one
(1) residence located east of County Road 73. No residences are within 500 feet of the SEF.
A siting analysis was performed in order to identify potential adverse impacts.
The siting analysis reviewed visual impacts, wildlife resources, sensitive soils, and wetlands and
waterways. Effects of dust and noise were also considered in separate reports. Visual impacts will
be addressed through the installation of landscaping screens. The application materials included
the following reports: a Photosim Visual Impact Analysis, a Critical Issues Analysis, a Technical
Memorandum for the Protected Species Report, a Dust and Weed Mitigation Plan, a Glare Study,
a Socioeconomic and Community Benefit Report, a Wetland and Waterbody Delineation Report,
an Environmental Conservation Measures Report, an Archaeology Class I File Search, along with
a Decommissioning and Reclamation Plan.
The visual impacts will be addressed through a Screening Plan. The 1041 USR map depicts a
triangular pattern of junipers along State Highway 79 and between Prospect and some of the
surrounding property owners' properties. This juniper screening will be placed: 1) along the east
and west side of State Highway 79 from County Road 4 extending south for one-half (1/2) mile
along State Highway 79; 2) along the south side of County Road 4 for about one -quarter (1/4) of a
mile extending west from State Highway 79; 3) and along the adjacent property boundary of the
Davis Residence (Corrected Lot A of RE -1445 part of the NE4 of Section 34, Ti N, R63VV). The Jeff
Erker property (Lot C of RE -4104 part of the SE4 of Section 30, T1 N, R62W) will be surrounded by
a (4) tall, eight (8) wide, 5,235' long berm will be placed along with the juniper trees along the top
of the berm. The operator will ensure that any dead or dying trees will be replaced so that the
screening will remain in place over the life of the project. Additionally, a Development Standard has
been added that states that the landscaping will be maintained and any plantings that are diseased
or dying shall be replaced within the growing season or next calendar year whichever occurs
sooner. The operator will also water the trees for one (1) year to ensure they are established.
Wildlife habitat and endangered wildlife species will not be significantly impacted. The subject
properties provide low to moderate habitat for various federal and state listed species. Setbacks
and wildlife corridors have been established to preserve the natural resources and connect
habitats. The applicant corresponded with the U.S. Fish and Wildlife Service and the Colorado
Parks and Wildlife (CPVV) departments prior to submitting the application and it was determined
that Prospect will not interfere or disturb habitat for listed and existing species. A 250 to 500 -foot
wildlife corridor has been incorporated into the design plan.
Localized soil stripping will be required for the inverters, substation, and laydown yards. This
topsoil, along with the soil from the stormwater ponds, will be stockpiled on site to form a four (4)
tall, eight (8) wide, 5,235' long berm that will be placed on the north and west property boundary of
the Jeffrey Erker property (Lot C of RE -4104 part of the SE4 of Section 30, Ti N, R62W). No soil
USR24-0013 I Prospect Solar, LLC
Page 7of23
stripping is planned under panels or at the screw pile locations, unless required to smooth out
localized knolls and depressions, or to facilitate appropriate stormwater runoff. Native plant seeding
will be incorporated between and around the solar arrays to restore the appearance of the site and
to promote the return of native species and pollinators. Drainage and vegetation will be preserved
and promoted throughout the site, with the location of the solar arrays to be built around the existing
Sand Creek and West Sand Creek. Southeast Weld Conservation District returned a referral dated
August 13, 2024, requesting a revegetation plan after construction, and to manage soil erosion
during construction.
Drainage patterns, flow rates, and runoff water quality will not be impacted by the solar facility
components. Installation of water quality or detention facilities will be implemented in accordance
with the project's drainage report. Appropriate temporary construction -related erosion and
sedimentation control "Best Management Practices" (BMPs) will be applied during the construction
phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality.
Prospect will mitigate the basins and re-establish native vegetation to reduce run-off and potentially
mitigate flooding risks around the immediate area. A Floodplain Development Permit is required
per the referral comments from the Floodplain Administrator dated July 9, 2024.
The Dust Abatement Plan will control the air pollution that will occur due to construction traffic and
grading. Dust mitigation includes actions like moistening the soil, spraying the roads with a dust
suppressant or binder (magnesium chloride and lignin mixture), monitoring for fugitive dust,
creating buffers between the neighboring properties, and post construction re -vegetation of
disturbed areas with a county approved seed mix. Vehicle tracking devices will be installed at truck
exit drives. The speed of the vehicles will be five (5) mph or less, to minimize dust emissions. The
site is generally flat and only spot grading is anticipated which will reduce the amount of dust.
Operators shall continuously employ the dust mitigation practices in order to control fugitive dust.
Prospect will generally be controlled remotely from the operator and local utility central control
centers. During normal operation, the solar field and substation may be accessed by the operator
and utility personnel to conduct routine inspections or maintenance, with limited dust creation and
negligible effects to local roadways. Operations and maintenance work is typically done monthly
and lasts only a few days, not requiring a full-time presence of more than 1-2 workers.
Noise and disruption related to construction include pile driving at 89 - 95db(A) and equipment
backup beeping (reverse warning sounds) of 97-112 db(A). This noise will be temporary in nature
and is not anticipated to exceed maximum levels at the property boundary for construction
activities. Additionally, the transformers, inverters and fans on the BESS create a humming noise
that may be noticeable to nearby residents or wildlife. It is anticipated that this noise will not exceed
the noise regulations as set forth by Weld County.
Any debris produced during construction will be promptly removed and disposed of properly by the
construction contractor.
The Glint and Glare Analysis was submitted with the application materials. The analysis was
reviewed the effects of the solar energy facility on nearby residences and on a privately owned
landing strip near the site. Worst -case scenario parameters were used for a conservative estimate.
Findings show that with appropriate system settings, it is unlikely that glare from the proposed solar
project will be problematic in any manner for the surrounding area and that this 1041 Solar Energy
Facility would pass the Federal Aviation Administration's 2021 policy regarding glint and glare
effects to commercial airports.
A security fence will be constructed around the perimeter of the Project to prevent the public from
entering the area.
The Decommissioning Plan states that the site will be returned to pre-existing conditions within
twelve (12) months of operation cessation. Monitoring and site restoration may extend beyond this
period to ensure successful revegetation and rehabilitation.

F. Section 21-7-350.C.6 -- The nature and location or expansion of the facility complies with all
applicable provisions of the master plan of this County and service areas, and other applicable
regional, metropolitan, state and national plans.
Prospect is generally located between County Road 67 and County Road 75 and between County
Road 2 and County Road 8. The site is not within a Coordinate Planning Agreement area (CPA) or
a three (3) mile referral area for any municipality.
The first responders and/or emergency services that are affected with this proposal include the
Sheriff's Department and the Southeast Weld Fire Protection District. The Weld County Sheriff's
Office submitted a referral agency response dated June 11, 2024 stating that they have no
concerns and the applicant has been in communication with the Fire District to discuss the source
and access to water in the event of an emergency.
The State of Colorado Division of Water Resources in their referral agency comments dated July
3, 2024 stated that a copy of well permit no. 322682 was included in the referral material. This
permit was approved pursuant to CRS 37-90-105 for a well on a tract of land of 160 acres described

stating that the applicant is required to go through the District's process of plan review/fees and
inspections prior to construction.
Construction of the Prospect will occur during daylight hours over the twenty-four to thirty-six (24
to 36) -month construction period. If construction activities continue past daylight, nighttime lighting
would be temporary and shielded. The application materials estimate that there will be 300-450
workers at the site. Construction will occur between the hours of 6:30 am to 3:30 pm Monday
through Saturday. The traffic narrative states that there will be three hundred (300) daily trips of
passenger vehicles, fifteen (15) daily water trucks, and fifteen (15) daily trips of heavy-duty trucks.
This volume of daily traffic of 660 trips are expected to be the highest volume generated during
construction of the solar facility. The application materials also state that it is believed that trips
generated by the construction of the Prospect and Janus projects will not have major impacts on
the transportation patterns or the roads in the area of the project site.
During normal operation, the solar field and substation may be accessed monthly by 1-2 workers
to conduct routine inspections or maintenance. These inspections may occur over a few days.
There will be no permanent cargo containers, with the exception of the O&M container, which will
be installed in the project substation area.
G. Section 21-7-350.C.7 -- The nature and location or expansion of the facility does not unduly or
unreasonably impact existing community services, nor will it create an expansion of the demand
for government services beyond the reasonable capacity of the community or region to provide
such services, as determined by the Board of County Commissioners.

The government services significantly affected with this proposal include, but are not limited to, first
responders and/or emergency services including the Sheriff's Department and the Southeast Weld
Fire Protection District. The Weld County Sheriffs Office submitted a referral agency response
dated June 11, 2024 stating that they have no concerns and the applicant has been in
communication with the Fire District to discuss the source and access to water in the event of an
emergency.
The application materials include an email summary, date July 6, 2023, that outlines a discussion
between the Southeast Weld Fire Protection District (District) and the applicant. The District stated
that a water tank on the projects site which can be used by the Fire District in the area would be
very helpful and that the applicant should determine how much water is needed for the projects
and then work out as much there is left available for the fire department to use based on the size
of the tank. The District also stated that the fire department shall be allowed to enter at any time
using a Knox -box key to open the gates and that the project layout must respect the fire code
spacing regulations to allow enough space for fire trucks to turn. The District requested a dust and
weed mitigation plan which has been included in the application materials.
The District submitted referral agency comments dated June 11, 2024, stating that the applicant
will be required to go through the District process of plan review, fees, and inspections prior and
during construction.
The Weld County School District RE -3J did not return a referral response.
H. Section 21-7-350. C.8 -- The nature and location of the facility or expansion will not unduly interfere
with existing easements, rights -of -way, other utilities, canals, mineral claims or roads.
The application materials state that Prospect is not anticipated to unduly interfere with existing,
canals, mineral interests, easements, ROWs, or other utilities. Canals and other irrigation channels
will be considered with construction phase of Prospect and that the irrigation pathways and ditches
have been marked and planned around within the site plan. The structures and channels will be
preserved on the property for possible future use of agriculture following the decommissioning of
the project.
Additionally, according to the State of Colorado Energy and Carbon Management Commission
(ECMC) maps seven (7) well bore permits have been filed on the site. Prospect is sited to avoid
existing oil and gas facilities and pipelines, surface use agreements, and reasonably
accommodates mineral access through appropriate setbacks that have been incorporated into
project design. The location of the SEF is in a low oil and gas producing area in the County and all
the wells on properties have expired and there are no reports of production to the ECMC.
Mineral estate owners were identified through a list provided by the Weld County Clerk and
Recorder. The applicant is communicating with these owners to obtain Surface Use Agreements
and will incorporate mineral access locations in the USR map as needed. The mineral owners were
notified of the public hearing for this 1041.
The Development Review referral agency comments dated July 9, 2024, state that Prospect solar
panels are proposed to be installed in/on the existing County Road 71 right-of-way (ROW). The
proposal is required to be revised to remove these panels from the ROW. Development Review's
referral expressed no concerns with the roads in the area.
The referral agency comments from Tri-State, dated June 24, 2024, indicate that the switching
station will need to be larger than two (2) acres as proposed. Tri-State typically requires ten (10) to
fifteen (15) acres for a switching station. Tri-State also has concerns with the proposed Project
schedule. Stating that operation of the facility is proposed for Summer of 2026, but execution of a
LGIA, procurement of switches and other materials, and 1041 permitting for a switching station will
not be feasible by 2026. Finally, Tri-State indicate that the application materials state that, "Tri-
State will permit, operate, and build a short 0.1 -mile long overhead 230kV gen-tie line." However,
USR24-0013 I Prospect Solar, LLC
Page 10 of 23
the referral agency comments state that Tri-State will not build the developer's gen-tie line. Tri-
State would build the lines to connect their switching station to the existing line, but the line to
connect the generation facility to the last span outside of the switching station will need to be
permitted and built by the developer.
In an email dated June 28, 2024, the applicant indicated that they would connect via a short 0.1
mile gen-tie from the project substation to a new 230 kV switching station that will be permitted,
built, and operated by Tri-state at the approximate co-ordinates of 40° 1'9.60"N, 104°23'42.11"W.
The applicant also discussed Tri-States concerns about the size of the switching station and
provided an updated map showing the larger acreage.
Prospect will maintain minimal impact on usage of utilities during construction. The substation and
switchyard are a part of the Prospect Solar Energy Facility (SEF).
I. Section 21-7-350.C.9 -- Adequate utilities exist or shall be developed to service the site, as
necessary.
Prospect's demand for utilities is low and the substation and switchyard will be constructed as part
of the Prospect Solar Energy Facility (SEF). Additionally, Prospect will connect via a short 0.1 -mile
gen-tie from the project substation to a new 230 kV switching station that will be permitted, built,
and operated by Tri-state at the approximate co-ordinates of 40° 1'9.60"N, 104°23'42.11"W.
Bottled water will be used during construction and Prospect will have no impacts on vested water
rights. Portable toilets are required the construction phase.
State of Colorado Division of Water Resources returned a referral dated July 3, 2024, stating "A
copy of well permit no. 322682 was included in the referral material. This permit was approved
pursuant to CRS 37-90-105 for a well on a tract of land of 160 acres described as the SW1/4 of
Section 24, Township 1 North, Section 63 West of the Sixth P.M., Weld County. Water from this
well may be used for domestic purposes inside two (2) single family dwellings, and the watering of
four (4) of the owner's own large non-commercial domestic animals (per single family dwelling),
irrigation of 2,000 square -feet of lawn and garden and the watering of livestock on range and
pasture. As permitted, this well cannot be used for the proposed solar facility, unless the well is re -
permitted to operate pursuant to a Determination of Water Rights and a Replacement Plan to be
approved by the Groundwater Commission."
J. Section 21-7-350.C.10 -- The nature and location for expansion of the facility will not unduly
interfere with any significant wildlife habitat or adversely affect any endangered wildlife species,
unique natural resource or historic landmark within the impact area.
Prospect is characterized as a utility -scale Solar Energy Facility (SEF) on 1,500 -acres. The
infrastructure required includes racking equipment, underground collection lines, a 100 -megawatt
AC (MWAC) Battery Energy Storage System (BESS), a step-up substation, transformer and
maintenance facilities, and a 230kV interconnecting transmission line to connect to a new Tri-State
Switching Station.
Prospect's location, generally between County Road 67 and County Road 75 and between County
Road 2 and County Road 8, is a remote area. There are three (3) USRs within one (1) mile of the
exterior boundary of the SEF: USR-1186 for 115 kV transmission lines, SUP -483 (USR-483) for a
gravel mine, and USR12-0039 for agricultural services. The adjacent land uses include pastures,
crops, vacant land, and some rural residences. Linear infrastructure includes a State Highway
(State Highway 79) and local, primarily gravel, roads. Lost Creek, Sand Creek, West Sand Creek,
and associated unnamed tributaries travel through the subject properties. Permanent removal of
the topsoil will be required for the inverters, substation, and laydown yards. Impacts to native
vegetation around the site are expected to be minimal.
Southeast Weld Conservation District returned a referral dated August 13, 2024, requesting a
revegetation plan after construction, and to manage soil erosion during construction.

Pivot irrigation was historically conducted utilizing leased water rights on a Corrected Lot B of RE -
1445 part of the NE4 of Section 34, T1 N, R63W (PN 147734000020). Upon permit approval, these
rights will transfer back to the original tenant. No additional irrigated prime agricultural land exists
on the subject properties.
The Colorado Parks and Wildlife (CPW) submitted referral agency comments dated June 18, 2024
that included information about incorporating one or more north -south movement corridors for
game, recommendations for conducting pre -construction nesting surveys, and requirements on
fencing types. The application materials included letters from both CPW and U.S. Fish and Wildlife
(FWS).
The applicant submitted an Environmental Conservation Measures report with the application
materials incorporating the comments of CPW and the FWS and it states, in part, that the final
layout of the solar arrays will avoid wetlands, waterways, and sensitive species habitats.
The US Department of Energy, the Environmental Protection Agency, the US Fish and Wildlife
Service, the US Army Corps of Engineers, and History Colorado, the State Historic Preservation
Office did not submit referral agency comments.
K. Section 21-7-350.C.11 -- The geological and topographic features of the site are adequate for all
construction, clearing, grading, drainage, vegetation and other needs of the facility construction or
expansion.
There are no significant geologic hazards or geologic areas of importance. The Colorado Geologic
Survey did not return a referral agency response. The prevalent natural hazard is flooding from Lost
Creek, Sand Creek, West Sand Creek, and associated unnamed tributaries that travel through the
Prospect SEF, south towards Adams County. These creeks are usually dry however, at times, they
have significant flows and high-water during storms evidence by scoured creek beds and a large
box culvert installed by the Colorado Department of Transportation (CDOT) under State Highway
79. Two of the subject parcels are traversed by theses creeks. The referral agency comments from
the Floodplain Administrator, dated July 1, 2024, state that although FEMA has not mapped the
floodplains in this are it is evident that portions of the 1,500 acres are in the floodplain and a Flood
Hazard Development Permit is required prior to construction. Apart from the creek beds the
topography is gently rolling (somewhat flat) and, according to the application materials, 160 acres
of the 1,500 acres are irrigated crop (sorghum and winter wheat) and the remainder is undeveloped
land. There are seven (7) total properties that contribute to the 1,500 acres and there is only one
built structure, an equipment building.
Localized soil stripping will be required for the inverters, substation, and laydown yards. This
topsoil, along with the soil from the stormwater ponds, will be stockpiled on site to form a berm
located on the boundary with (part of the W2 Section 30, Ti N, R62W (PN 147930000001). No soil
stripping is planned under panels or at the screw pile locations, unless required to smooth out
localized knolls and depressions, or to facilitate appropriate stormwater runoff. Drainage and
vegetation will be preserved and promoted throughout the site, with site plans built around the
existing Sand Creek and West Sand Creek.
Southeast Weld Conservation District returned a referral dated August 13, 2024, requesting a
revegetation plan after construction, and to manage soil erosion during construction.
L. Section 21-7-350. C.12 -- The existing water quality of affected state waters will not be degraded
below state and federal standards or established baseline levels.
The application materials included a Wetland and Waterbody Delineation Report (October 2022)
that states that there are six (6) acres identified in the National Wetlands Inventory (NWI) of
wetlands and three (3) waterbodies (Sand Creek, West Sand Creek, and an unnamed tributary to
Sand Creek) that total 1.4 linear miles. The wetlands and the waterbodies overlap. Sand Creek is
the one (1) water body that is potentially jurisdictional. No jurisdictional wetlands were identified.

Lost Creek, Sand Creek, West Sand Creek, and associated unnamed tributaries travel through the
Prospect SEF, south towards Adams County. These creeks are usually dry however, during storms
events, they have significant flows and high-water evidence by scoured creek beds and a large box
culvert installed by the Colorado Department of Transportation (CDOT) under State Highway 79.
Two of the subject parcels are traversed by theses creeks. The referral agency comments from the
Floodplain Administrator, dated July 1, 2024, state that although FEMA has not mapped the
floodplains in this are it is evident that portions of the 1,500 acres are in the floodplain and a Flood
Hazard Development Permit is required prior to construction.
The US Army Corps of Engineers did not submit a referral agency response.
Prospect will not impact hydrologic flow of surface water or groundwater, and it will not affect
groundwater recharge. Prior to construction, a Storm Water Permit for Construction Activities would
be acquired from the Colorado Department of Public Health and Environment (CDPHE).
Prospect will include setbacks per state mandates for all wells, active or abandoned, to ensure no
contamination or impacts to surface waterways or ground water. No discharge of contaminants or
other materials will occur to state waters as a result of this Project.
M. Section 21-7-350.C.13 -- The proposed project will not have a significantly adverse net effect on
the capacities or functioning of streams, lakes and reservoirs in the impact area.
Lost Creek, Sand Creek, West Sand Creek, and associated unnamed tributaries travel through the
Prospect SEF, south towards Adams County. Prospect's configuration will avoid these stream beds
and any Waters of the United States (WOTUS) and the final layout of the solar arrays will also
avoid wetlands and sensitive species habitats.
N. Section 21-7-350.C.14 -- The benefits of the proposed developments over the life of the project
outweigh the temporary losses of any natural resources or reduction of productivity of agricultural
lands as a result of the proposed development.
The 1,500 -acres is generally located between County Road 67 and County Road 75 and between
County Road 2 and County Road 8. This is a remote area of the County. There are seven (7)
affected properties that contribute to the 1,500 acres and there is only one built structure, an
equipment building. Apart from the creek beds the topography is generally flat and the 1,500 acres
consist of undeveloped land along with cultivated cropland, including sorghum and winter wheat.
The Southeast Weld Conservation District's referral dated August 13, 2024 include
recommendations that the applicant conserve natural resources through the implementation of a
revegetation and soil conservation plan, including, but not limited to, pre -planting grass seed,
installing hedgerows or windbreaks, and practicing soil conservation measures.
Grasses and other low -growth species will be seeded beneath the panels to reduce soil erosion
and the weeds will be managed. The loss of natural resources will be negligible, and, at the time of
decommissioning, the land will be restored to its previous condition for future uses. Prospect
reduces the negative impacts by avoiding sensitive environmental areas like the creek beds and it
does not produce hazardous waste.
Weeds will be managed by the following methods:
1) Planting native or desirable plant species for site colonization and promoting healthy vegetation
communities in reclaimed areas. Preventing unnecessary ground disturbance through precise
planning of construction projects and other activities. Managing the prompt revegetation of
disturbed areas.
2) Mowing, pulling, disking, and plowing may be used on weedy species for which these
treatments are effective.
USR24-0013 I Prospect Solar, LLC
Page 13 of 23
3) Introduce insects or other biologic agents which are known to inhibit or prevent reproduction of
noxious weed species. If biological agents are employed, control methods will be coordinated
with the Colorado Department of Agricultural Insectary in Palisade, Colorado.
4) Application of appropriate herbicides by a licensed applicator. All herbicides will be applied in
accordance with the manufacturer's label and in accordance with Colorado laws.
Prospect will produce alternative energy that will help the state and local communities achieve
Colorado energy goals. Additionally, as previously stated, the positive socioeconomic impacts
include employment opportunities during the short term (construction phase) as well as the long-
term (operational phase). These opportunities consist of direct construction and maintenance jobs
in addition to indirect effects such as supply chain purchases, construction in the form of grading,
structural, and electrical installations, as well as local building materials like gravel and concrete
which support industries in logistics and other professional services that are likely sourced locally.
Prospect requires minimal governmental services and the installation of the SEF will supplement
landowner income.
O. Section 21-7-350.C.15 -- The applicant has obtained or will obtain all property rights, permits and
approvals necessary for the proposed project, including surface, mineral access rights and
easements for drainage, utilities, access, etc. If the applicant has not obtained all necessary
property rights, permits and approvals, the Board may, at its discretion, grant the permit conditioned
upon completion of the acquisition of such rights prior to issuance of a building permit by the
County.
According to the application materials the necessary lease agreements have been obtained and
recorded with the Weld County Clerk and Recorder. Prospect will obtain building permits after this
USR is recorded. Prospect is in the process of obtaining the necessary ditch agreements and
County Road ROW access permits.
According to the Critical Issues Analysis submitted with the application materials the permits
required prior to construction and operation include, but are not limited to, a Weld County grading
permit, a Weld County right-of-way permit, Weld County building permits, Colorado Department of
Public Health and Environment (CDPHE) Colorado Pollutant Discharge Elimination System
(CPDES) permit, Colorado Department of Transportation (CDOT) access permits, and U.S.
Environmental Protection Agency (USEPA) Spill Prevention, Containment, and Countermeasures
(SPCC) Plan, U.S. Army Corp of Engineers Nationwide for work in the wetlands . Prospect will
avoid the Waters of the United States (WOTUS).
P. Section 21-7-350.C.16 -- The proposed project will not present an unreasonable risk of exposure
to or release of toxic or hazardous substances within the impact area.
The application materials stated that Prospect will not present an unreasonable risk of exposure to
or release of toxic or hazardous substances. The solar modules are composed solely of solid
materials, contain no cadmium, and a small amount of lead that is well under Federal limits. During
operation, maintenance will generally include only inert substances such as water for washing the
panels. No fuel or raw materials will be stored onsite during operations.
During construction, fuel, raw materials, equipment, and related items will be maintained per a Spill
Prevention, Control, and Countermeasures (SPCC) Plan. The contractor will prepare and adhere
to the SPCC Plan to ensure that petroleum products and hazardous materials are managed
appropriately. Compliance with U.S. Environmental Protection Agency (USEPA) Resource
Conservation and Recovery Act laws governing the proper management of solid and hazardous
waste will be closely followed for all waste disposals. The SPCC Plan will ensure that liquids and
gases used in construction will be contained and managed in accordance with county, state, and
federal requirements.
The Project will also include the construction of a Battery Energy Storage System (BESS). The
BESS is lithium ion based and is designed to meet the recommendations and requirements from
local authorities (i.e., Southeast Weld Fire District) regarding fire, safety, and noise. The project
USR24-0013 I Prospect Solar, LLC
Page 14 of 23
and battery supplier will comply with USEPA regional chemical reporting requirements for batteries
and hazardous materials.
The Weld County Office of Emergency Management (OEM) submitted referral agency comments,
dated September 9, 2024, stating that the operators of Prospect are required to provide adequate
training for first responders on the BESS units. The applicant will need to work closely with Chief
Beach of the Southeast Weld Fire Protection District (SEWFPD) to ensure this training occurs.
This recommendation is based, in part, upon a review of the application materials submitted by the

Diana,
Thank you for your time as well. Here is the information for each of the items you requested, as well as
answers to other questions you posed:
1. The letter about the division of the properties and the intent.
We acknowledge that Swank and Erker are both included in both projects, and therefore we will divide
their parcels so that each USR is on its own legal lot. We will keep you apprised of our progress
(estimated 30-45 days).
2. All the Certificate of Conveyances (sometimes called a Chain of Title). Please keep in mind that
the conveyances (deeds) need to be dated between 1972 (or before) to today. So for example, once
the two parcels are split those new deeds will need to be submitted. There will be 4 new needs as
we discussed.
Requested.
3. The information about the switching stating vs substation and if it exists or is being built.
Prospect Solar will interconnect at Tri-State's switchyard, which is yet to be built and its future location is
shown in the Plot Plan C302 submitted (labelled as "Tri-State Switchyard"). The project has set aside
land to transfer to Tri-State for the switchyard that will be built by the utility for the project. The name of
the switchyard has not been chosen byTriState yet. The Prospect substation and the Tri-State switchyard
will both operate at 230 kV.
Janus Solar will interconnect at WAPA's Sand Creek switchyard. This is Western Area Power Authority's
future substation that has been permitted by Weld County on the Hernandez parcel 147725200001. The
approximate location of the WAPA Sand Creek Switchyard is shown on the Janus Conceptual Site Plan
(as well as 1041 SEF Permit Map and Plot Plan C302). The Janus substation and the WAPA switchyard will
both operate at 115 kV.
3. Utility Company Interconnection Agreement
1
Please find attached the System Impact Study and Facility Study Agreement executed with Tri-State for
Prospect, and the SIS and FS Agreements executed with WAPA for Janus, demonstrating the projects
have applied to and are undergoing interconnection studies with the respective utility.
4. Kevin L Helzer and Lorie L Helzer
We understand that 2b_Auth Statement of Authority4KL.PDF shows that 20 years ago Kevin L Helzer and
Lorie L. Helzer were partners and both had signed the Statement of Authority, yet the Memo of
Lease_4KL.PDF only includes Lorie's signature. Please note Lorie Helzer is the Manager of 41<L LLC, the
owner of that tract of land, therefore she is the only one required to sign. With respect to the other parcel,
which is under their name, they have both signed as tenants in common. Therefore no additional
signatures are required. Both Kevin and Lorie also signed the Weld County 1041/USR Authorization Form,
attached.
6. Is every inverter coupled with the DC BESS? How many BESSs are proposed for each project?
Yes direct current (DC) BESS are coupled with inverters rather than consolidated in a single location. For
Prospect there are 32 BESS DC -coupled inverters and 56 Solar PV inverters. For Janus there are 7 DC -
coupled inverters and 23 Solar PV inverters. Please refer to the previously provided April 2024 conceptual
site layout for both projects, where is shown the inverters that are coupled with the DC BESS in purple,
and the standard Solar PV inverters in green.
Roger (copied) is working with the County attorney to finalise the waiver schedule. As we work on items
#1 and 2 —which will be provided before the staff report — we ask that the County begin the referral
agency process. We will continue to provide updates and commitments. Do you concur with this
approach?
Respectfully,

Hi Jeremy:
Thank you for calling me on Friday. I enjoyed meeting your team. I think we had a great conversation,
especially for me as I now know quite a bit more about the project. This is not a complete list of all we
discussed but please submit:
1. The letter about the division of the properties and the intent.

2. All the Certificate of Conveyances (sometimes called a Chain of Title). Please keep in mind that the
conveyances (deeds) need to be dated between 1972 (or before) to today. So for example, once the

3. The information about the switching stating vs substation and if it exists or is being built. I plan to drive
out there and see if I can see it too. And the name — are there two or one known by two names.
Thanks again,
