PROJECT DESCRIPTION (SATISFIES 21 -3-330 .C. 1 .A-G)
INTRODUCTION
This document is being submitted by Tri-State Generation and Transmission Association , Inc.
(Tri-State) to request review of Phase II of the proposed Southwest Weld Expansion Project
(SWEP or Project) under the provisions of the Weld County 1041 process. This submittal
includes the purpose and need and description of the proposed Project, which is situated on
privately owned property in Weld County.
Who is Tri-State?
Tri-State is a wholesale electric power supplier owned by the 44 electric cooperatives and
public power districts (the "Member Systems") that it serves. Tri-State generates and
transports electricity to its member systems throughout a 200,000-square-mile service
territory across Colorado, Nebraska, New

PROJECT DESCRIPTION
Tri-State is proposing to construct a series of new transmission lines and substations, called
the Southwest Weld Expansion Project, to establish new delivery points for its Member
Systems, United Power. The Project will be located in rural Weld County, northwest of
Hudson , Colorado, and is primarily intended to serve existing load and the growing oil and
gas development in the area. Phase II of the project will include the following components
(Figure 1A):
A new 115/69/13.2-kilovolt (kV) substation located west of the town of Hudson called the
Colfer Substation. This substation will replace United Power's existing Hudson
Substation .
Approximately 9 miles of 230/115-kV transmission line from Tri-State's Greenhouse
Substation (approved as part of Phase I ) to the proposed Colfer Substation .
A new 115/69/13.2-kV substation located off of County Roads 49 and 30 called the
Rattlesnake Ridge Substation
Approximately 8.5 miles of 230/115-kV transmission line from the proposed Colfer
Substation north to the proposed Rattlesnake Ridge Substation

United Power will construct distribution lines (< 115-kv, and as defined in Section 23. 1 .90 of
Weld County Code) out of the various substations, not included as part of this Project, and a
use allowed by right in the Agricultural Zone District.
The substation and transmission line construction is expected to begin in mid-2016 and the
facilities are expected to be in-service between late-2016 and late-2017. The proposed
transmission lines will be approximately 30.5 miles in length and located entirely on private
lands. The proposed 230/115-kV transmission lines will be built to be capable of 230-kV, but
one circuit will be operated initially at 115-kV. The new 115-kV and 230/115-kV transmission
lines will be constructed out of wood and self-weathering steel. The right-of-way will be 150-
feet-wide.
The Project occurs primarily in unincorporated Weld County. The transmission lines coming
out of the Greenhouse substation would be located within the City of Fort Lupton.
Approximately 0.5 mile of the Colfer to Rattlesnake Ridge transmission line is located within
the Southeast Weld Regional Urbanization Area (RUA).
PURPOSE AND NEED
Tri-State is a regional, wholesale electric power supplier owned by the Member Systems that
it serves. Tri-State is obligated to provide reliable, efficient, cost-based , wholesale power to
these Member Systems, who in turn provide retail electric service to their end-use member-
consumers.
United Power, one of Tri-State's Member Systems, has received formal requests for service
to several large industrial loads in southwest Weld County primarily for oil and gas extraction ,
processing , and transportation. These load requests include approximately 100 megawatts
(MW) for oil and gas production facilities, 90 MW for gas processing plants, and 120 MW for
oil and gas transportation . The transportation loads consist of twelve compressor sites each
2
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
with a demand of 10-12 MW. Additionally, United Power anticipates a significant amount of
native residential load growth in support of oil and gas development. Together, these retail
load requests exceed 300 MW and cannot be accommodated by United Power's existing
34.5-kV sub-transmission and distribution systems in the area.
Tri-State has also received inquiries from one of its other members, Poudre Valley Rural
Electric Association (PVREA) for up to an additional 50 MW in the area south of Kersey and
immediately north of United Power's service area. In addition to the upgrades approved by
the Weld County Board of County Commissioners on February 4, 2015 for Phase I of the
project (USR14-0067), the electrical infrastructure to serve these needs will be completed as
part of this Phase II of the Southwest Weld Expansion Project (Figure 1A) and will include a
substation, called Neres Canal, which would be served by the Milton substation and would be
included in the operator's County permit application for the gas plant.
Tri-State is also working with Xcel Energy (Xcel), the other utility that serves southwest Weld
County. Tri-State and Xcel have entered into an agreement which would allow Xcel to be a
partner on the project pending negotiation of a participation agreement that would meet the
load-serving needs for both companies in the most efficient way possible, and would include,
at a minimum , a connection from Xcel's Hudson — Fort Lupton 115kV line to the new Colfer
Substation (approximately 500' of transmission line).

ALTERNATIVES TO THE PROPOSED PROJECT
Transmission System Alternatives
Two electrical system alternatives were evaluated to address the need for the Project.
Alternative A: No Action
Taking no action would result in no power delivery to Tri-State's Members and their
customers. The No Action Alternative does not meet the need of the Project and would
require oil and gas operators to "self-generate" to meet their power needs and to obtain the
accompanying air permits to do so.
Alternative B: New Substations and 115-kV and 230-kV Transmission Line Connections
Tri-State evaluated transmission (230-kV and 115-kV), sub-transmission (69-kV and 34.5-
kV), and distribution alternatives to meet United Power's forecasted loads and to develop a
coordinated distribution and transmission plan for the area. The studies concluded that: 1 ) 69
and 13.2-kV is the preferred delivery voltage for serving the numerous compressor station
and other loads in the area; 2) additions to existing substations as well as new substations
would be required to serve the various loads; and 3) certain 230-kV and 115-kV facilities are
required to source the new 115/13.2-kV substations and 69-kV sub-transmission system .
This alternative would involve the construction of approximately 30.5 miles of 230-kV and
115-kV transmission line and three new substations. Alternative B would provide the
necessary power to serve oil and gas facilities in the area, as requested by Member
customers.
The preferred system alternative is Alternative B . Alternative B meets the Project's purpose
and need and provides a cost-effective, secure, and reliable source of power for Tri-State's
Members, United Power, PVREA, and their customers.
Transmission Line Routing Alternatives
The process used to identify alternative locations for the transmission lines began with
delineating the Study Area (for all phases of the Project). The general location for the
substation site and the transmission lines were initially identified based on the location of the
oil and gas facilities, interconnection considerations, existing infrastructure, and residences.
The locations of these features heavily influenced the area of consideration for the
transmission lines and substations. A Transmission Routing Study was completed for the
Study Area (Appendix A) to help determine potential routes for the Project based on a
number of criteria, including , but not limited to the following :
Li Length following existing linear features
Number of residences in proximity
• Agricultural uses (e.g. center pivots)

A detailed description of the Transmission Routing Study is provided in Section 21 -3-330. B.6,
and in Appendix A. A summary of the alternatives for each segment of the Project is provided
in Figure 1B and summarized in Tables 1 and 2.
Greenhouse Substation to Colfer Substation ;Greenhouse—Colfer;
The preliminary routes for the proposed 230-kV Greenhouse—Colfer transmission line were
identified along existing transmission lines, Highway 52, and field lines (Figure 1 B). An
existing utility corridor, which is located directly northeast of the Greenhouse Substation and
going east toward Hudson, presented an opportunity for routing , although the corridor
crosses near two residences and is approximately 1 .4 miles from the Platte Valley Airpark.
An additional route was identified to the north that avoids the residential crossing, but passes
near four additional residences. A route to the south along Highway 52 was also evaluated
because of the potential to consolidate disturbance with the highway corridor.
Greenhouse—Colfer Preferred Route
The Preferred route (Figure 1 B) makes use of the existing utility corridor between the
Greenhouse Substation and the Hudson area. The route has the fewest residences within
both 200 feet and 500 feet and the fewest number of center pivots within 75 feet of the right-
of-way (ROW). The Preferred route is approximately 1 .06 miles from the Platte Valley Airpark
but is adjacent to an existing transmission line, and would be located on the north side of the
existing line, away from the airport to the south .
Greenhouse—Colfer Alternative 1
Alternative 1 (Figure 1 B) follows the Preferred route to the north but then turns east
approximately 0.5 mile north of the Preferred route along County Road 20. This route is
parallel to County Road 20 for most of the route; however, it would create an additional
corridor approximately 0.5 mile from the existing corridor. This route is the longest and
crosses within 75 feet of four center pivots (twice as many as the other alternatives) (Table
1 ). This route would also impact twice as many residences as the Preferred route.
Greenhouse—Colfer Alternative 2
Alternative 2 (Figure 1 B) runs east out of the Greenhouse Substation to the Hudson area
(proposed Colfer Substation) south of the other alternatives along Highway 52 . This route is
the shortest and occurs next to the fewest number of oil and gas facilities; however, it would
impact nearly five times as many residences as the Preferred route and would impact the
most landowners (Table 1 ). Alternative 2 is also the closest to the Platte Valley Airpark and
would create a new obstruction for the airport to the south .

Colfer Substation to Rattlesnake Ridge Substation (Colfer—Rattlesnake Ridge)
The area between the Colfer Substation and the Rattlesnake Ridge Substation is primarily
agricultural land (center pivots and pasture lands) with intermittent residential development.
Preliminary routes for the Colfer—Rattlesnake transmission line were identified along field
lines and County roads. An addition route that follows an existing transmission line owned by
Xcel Energy (Xcel) to the east was also evaluated .
Colfer—Rattlesnake Ridge Preferred Route
The Preferred route begins at the proposed Colfer Substation property and heads due west
parallel to Xcel's existing Hudson—Fort Lupton line for approximately 0.8 mile where it turns
due north and runs along property boundaries for 2.5 miles. The route then crosses the
existing east-west utility corridor and continues north for another 1 .5 miles where it turns
north to the Rattlesnake Ridge Substation parcel.
This route is the shortest length of the Colfer—Rattlesnake Ridge alternatives, and has the
fewest number of road crossings. It also has the fewest number of residences and the fewest
landowners impacted (Table 2).
Colfer—Rattlesnake Ridge Alternative 1
Alternative 1 heads west out of the Colfer Substation for approximately 1 .8 miles where it
heads north for 2.5 miles along County Road 41 (Figure 1 B). The transmission line would
have to cross the County Road four times along this stretch to avoid homes and oil and gas
facilities, and additional crossing could be required upon final engineering . The route then
heads to the east for approximately 1 mile where it heads north again along County Road 43
for 3 miles. The route would have to cross the County Road 9 times along this stretch to
avoid homes and oil and gas facilities. The route then goes west for 2.5 miles along County
Road 20 where it crosses back-and-forth another two times.
Alternative 1 has the highest percentage of the route adjacent to linear features (County
Roads); however it has a large amount of residences within 5OO feet of the centerline (23)
11
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
and a large amount of center pivots (24) (Table 2). The amount of corner structures required
for all of the road crossings could make the route cost prohibitive.
Colfer-Rattlesnake Ridge Alternative 2
This route goes south out of the Colfer Substation property for approximately 0.5 mile to the
existing Hudson Substation . It then follows Xcel's existing Ennis—Hudson transmission line for
7.8 miles, crossing County Road 49 twice. The route then heads north off of the existing
corridor for 3 miles.
This route is the longest of the Colfer—Rattlesnake Ridge alternatives and has the majority of
its route adjacent to existing transmission line corridors. However, it crosses within 500 feet
of six residences and impacts 17 landowners. Additionally, it is within 200 feet of 10 oil and
gas facilities.

Rattlesnake Ridge Substation to Milton Substation ;Rattlesnake Ridge—Milton;
The area between the Rattlesnake Ridge Substation and the Milton Substation is dominated
by oil and gas development, agricultural land uses, and rural residents. The County Road 49
corridor runs between the two substations and is proposed for substantial widening and re-
alignment in the coming years. Alternatives were evaluated that included use of the existing
disturbed County Road 49 corridor and also routes to the east and west of the corridor to
avoid oil and gas facilities, residences, and agricultural operations.

Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
Rattlesnake Ridge—Milton Preferred Route
The Preferred route out of the Rattlesnake Ridge Substation crosses County Road 40 at the
intersection of County Road 44 and heads north, just east of the future road alignment for
approximately 3.3 miles. It then diverts to the west off of the road to avoid homes and crosses
through land owned by the State of Colorado. It crosses back into the County Road 49
alignment near County road 42 and continues north for 1 .2 miles where it terminates at the
Milton Substation. This route was the shortest and had the fewest number of road crossings
and residences and landowners impacted (Table 3).
Rattlesnake Ridge—Milton Alternative 1
Alternative 1 crosses County Road 49 out of the Rattlesnake Ridge Substation and heads
east along County Road 30 for approximately 0.5 mile where it turns north and runs along
property boundaries approximately 5 miles where it rejoins the County Road 49 alignment. It
then parallels the road to the north for another 1 .8 miles, crossing the road three times to
avoid homes and oil and gas facilities. The route then diverts to the northwest for 3.5 miles
until it crosses County Road 44 and returns the 1 .4 miles to the east to terminate at the Milton
Substation .
Rattlesnake Ridge—Milton Alternative 2
Alternative 2 goes east along County Road 30 out of the Rattlesnake Ridge Substation for
2 miles where it turns to the north and runs along property lines for another 2 miles. It then
alternates to the east and west for approximately 9 miles until it reaches County Road 49
where it turns west for 1 .5 miles to the Milton Substation .

Milton Substation to South Kersey Substation (Milton—South Kersey)
The area between the Milton Substation and the South Kersey Substation includes two
airports, which dominated the routing efforts in this area. The Easton Valley View Airport
occurs along County Road 49 approximately 1 .2 miles north of the Milton Substation. The
Beaugh Field , which is a private airstrip, is located northeast of the Milton Substation
approximately 0.3 mile east of County Road 51 . The area also includes center pivots and
irrigated agriculture, residences, and oil and gas wells and tank batteries.
Milton—South Kersey Preferred Route
The Preferred route runs north out of the Milton Substation and turns to the east along the
southern boundary of a parcel owned by Noble Energy. The route then continues north along
the west side of the Noble parcel for approximately 0.5 mile where it turns to the northeast
and then north through two parcels. The route does not occur along parcel boundaries on
these properties due to the approach and departure zone for the Easton Valley View Airport.
North of County Road 48 the route then re-joins the parcel boundary and continues to the
north for 0.75 mile where it crosses County Road 50 onto a parcel owned by DCP Midstream
and into the South Kersey Substation.
Milton-South Kersey Alternative 1
Alternative 1 also runs north out of the Milton Substation and then east across the southern
boundary of the Noble parcel. It then continues east for 0.5 mile where it turns north along
County Road 51 . This route would cross County Road 51 seven times to avoid residences
and oil and gas facilities before crossing County Road 50 into the South Kersey Substation .
This route was not selected because of the congestion along County Road 51 . This route
would include purchasing and relocating one homeowner (Table 4).
Milton—South Kersey Alternative 2
Alternative 2 follows the same route as the Preferred Alternative and Alternative 1 out of the
substation and east across the Noble parcel. It would then continue east for 0.9 mile where it
would turn north along parcel boundaries. The route would jog to the west to avoid a center
pivot along County Road 48 and would then jog west again to stay along parcel boundaries. It
would continue north from there into the South Kersey Substation . This route would involve
purchasing and discontinuing use of the Beaugh airfield (Table 4).

USE BY SPECIAL REVIEW APPLICATION CHAPTER 23, ARTICLE II,
DIVISION 4 OF THE WELD COUNTY CODE
23-2-240 . DESIGN STANDARDS.
A. An applicant for a Use by Special Review shall demonstrate compliance with the following
design standards in the application and shall continue to meet these standards if approved
for DEVELOPMENT.
1 . Adequate water service in terms of quality, quantity and dependability is available to the
site to serve the USES permitted.
Not applicable. The use being permitted includes transmission lines and substations,
which do not require water service. Bottled water will be used at the staging areas.
2. Adequate sewer service is available to the site to serve the USES permitted.
Not applicable. The use being permitted includes transmission lines and substations,
which do not require sewer service. Portable toilets will be used during construction .
3. If soil conditions on the site are such that they present moderate or severe limitations to
the construction of STRUCTURES or facilities proposed for the site, the applicant has
demonstrated how much limitations can and will be mitigated.
Nearly all of the soils along the transmission rights-of-way and the substations have
low shrink/swell potential as described in Section 23-2-260 and shown in associated
Figure 5. The majority of the soils are not limited for structures. However, Tri-State
will perform geotechnical studies at the substation sites. The soils study will identify
the structural characteristics of the soil and provide recommendations for
construction of foundations within the soils. Appendix D includes a soil report
prepared by the Natural Resources Conservation Service (NRCS). See also Section
21 -3-330. B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and
Noise Impacts.
4. Adequate fire protection measures are available on the site for the STRUCTURES and
facilities permitted.
The proposed transmission lines and substation are designed with overhead ground
wires and grounded towers to protect the system from becoming damaged by
lightning . See Section 21 -3-330. B.5.g—Hazards and Emergency Procedures for
additional fire protection measures.
5. USES shall comply with the following stormwater management standards:
a. Stormwater retention facilities shall be provided on site, which are designed to
retain the stormwater runoff from the fully developed site from a one-hundred-year
storm or as otherwise required by the Department of Public Works. In the case of a
LIVESTOCK CONFINEMENT OPERATION (L.C.O.), wastewater collection,
conveyance and retention facilities shall be designed and constructed in
17
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
accordance with the Confined Animal Feeding Operation Control Regulations (5
CCR 1002-19).
A range of measures to ensure that the Project does not impact water quality,
among other things, is listed in Appendix C, and prior to construction, a Storm
Water Permit for Construction Activities would be acquired from the Colorado
Department of Public Health and Environment (CDPHE). The Storm Water
Management Plan prepared as part of the Storm Water Permit will include the
use of sediment control measures, covering of exposed soils, and other
established Best Management Practices (BMP) that will control runoff. See
Sections 21 -3-330. B. 12—Air and Water Pollution Impacts and Control
Alternatives, Air Pollution Impact and Control , and 21 -3-330. B. 16-Surface and
Subsurface Drainage.
b. The drainage facilities shall be designed to release the retained water at a quantity
and rate not to exceed the quantity and rate of a five-year storm falling on the
UNDEVELOPED site.
There would be no alteration in the pattern or intensity of surface drainage as a
result of construction or operation of the transmission lines. Drainage from the
substations would be directed towards detention pond(s) located on the
substation properties. Drainage plans will be prepared for the Rattlesnake Ridge
Substation , the Milton Substation , and the Colfer Substation .
6. All parking and vehicle storage shall be provided on the site; parking shall not be
permitted within any public right-of-way. An adequate parking area shall be provided to
meet the parking needs of employees, company vehicles, visitors and customers.
During construction , all vehicles would be parked at the staging areas on County
Road 18, at the Colfer and South Kersey staging areas, and on County Road 43
(Figure 1 B), and no parking areas would be constructed. No parking would occur
within any public right-of-way. Only a small portion of the transmission line right-of-
way would be disturbed for vehicle access. See Section 21 -3-330. B.2 .b—Access to
the Project Area.
7. The USE shall comply with all the SETBACK and OFFSET requirements of the zone
district.
The portions of the Project located in unincorporated Weld County are within the A
(Agricultural) Zone District. The minimum setback in the A zone is 20 feet, and the
minimum offset is 3 feet, or 1 foot for each 3 feet of building height, as defined in
Section 23-3-50 of the Weld County Code. The transmission and substation
structures proposed as part of this project comply with the County setback and offset
requirements.
18
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
8. The access shall be located and designed to be safe; ingress and egress shall not
present a safety hazard to the traveling public or to the vehicle accessing the property.
For USES generating high traffic volumes and large number of large, slow-accelerating
vehicles, acceleration and deceleration lanes may be required to mitigate a potential
traffic hazard.
No adverse effects on county roads are anticipated. Access roads would be created
off of the following County roads for the substations and staging areas (Figure 1 B):
County Road 18 staging area—County Road 18
Colfer staging area—County Road 16
County Road 43 staging area—County Roads 43 and 30
South Kersey staging area—County Road 51
Tri-State will submit Access Road Permit applications and will comply with all County
design standards.
All mobile construction equipment would be certified to operate on Interstate
highways. There may be short periods of time when traffic would be halted on county
roads to allow construction vehicles to enter and exit the construction areas. No
improvements to roads in Weld County would be required . See Section 21 -3-
330. B.7—Natural and Socioeconomic Environmental Impacts from Construction of
the Electric Transmission Line.
9. New accesses to public rights-of-way shall be constructed using the following as
minimum standards:
a. Size of drainage structure—twelve (12) inches in diameter.
b. Length of drainage structure—twenty (20) feet.
c. Depth of cover over pipe—twelve (12) inches.
d. Width of access—fifteen (15) feet.
e. Maximum grade of access—fifteen percent (15%).
f. Flare radius—twenty (20) feet.
g. Depth of surfacing—four (4) inches.
Standards exceeding these minimums may be required depending on the type and
volume of vehicles generated by the type of USE proposed.
Access roads would be created off county roads for the substations and staging
areas, as described above. Access roads would be 25 feet-wide with a minimum
inside flare radius of 50 feet. The roads would be designed with a 6 inch section of
modified Class 5 road base. Tri-State will submit Access Road Permit applications
and will comply with all County design standards.
19
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
10. Buffering or SCREENING of the proposed USE from ADJACENT properties may be
required in order to make the determination that the proposed USE is compatible with
the surrounding uses. Buffering or SCREENING may be accomplished through a
combination of berming, landscaping and fencing.
The proposed use (electric transmission) and the proposed structures (utility poles
and substation structures) are compatible with the other uses and structures within
and adjacent to the Agricultural Zone district. This zone district contains existing
electric transmission and distribution lines, existing substations, and extensive oil and
gas development, making their appearance and operation balanced with the
surrounding uses.
11 . Uses by Special Review in the A (Agricultural) Zone District shall be located on the least
prime soils on the property in question unless the applicant can demonstrate why such
a location would be impractical or infeasible.
Numerous soil types along the transmission lines are designated as Prime Farmlands
or Farmlands of Statewide or Local Importance (Figure 2). However, placement of
the transmission line structures would not preclude the use of farmland under the
suspended transmission line. Approximately 32 acres of the right-of-way is
considered Prime Farmland , if Irrigated or Drained (Figure 2). There are
approximately 71 acres of Farmland of Statewide Importance on the 150-foot right-of-
way. However, only a small portion of the soils in the right-of-way would be disturbed
for the Project (less than 1 acre of permanent disturbance for the transmission lines).
Approximately 35% of the Colfer Substation is considered Farmland of Statewide
Importance and 10% of the Rattlesnake Ridge Substation is considered Prime
Farmland if Irrigated (Figures 3A-3C). However, the Colfer Substation is not currently
being used for agriculture because of oil and gas development and the parcel
proposed for the Rattlesnake Ridge Substation is proposed for multiple oil and gas
facilities, exclusive of the substation . See Section 21 -3-330. B. 15—Hydrologic,
Atmospheric, Geologic, Pedologic, Biotic, Visual , and Noise Impacts.
B. If the Special Review Permit for a MAJOR FACILITY OF A PUBLIC UTILITY OR PUBLIC
AGENCY is approved, the Planning Commission shall arrange for the Department of
Planning Services to record the appropriate Facilities Plan, Utility Line or Selected Route
Map with the County Clerk and Recorder. (Weld County Codification Ordinance 2000-1 )

An applicant for a Special Review Permit shall demonstrate conformance with the following
operation standards in the Special Review Permit application to the extent that the standards
affect location, layout and design of the Use by Special Review prior to construction and
operation. Once operational, the operation of the USES permitted shall conform to these
standards.
A. The operation of the USES shall comply with the noise standards enumerated in Section 25-
12-101 , C.R.S.
The Project would be constructed and maintained in accordance with Colorado Revised
Statutes 25-12-101 et seq . (Noise Abatement) and Article IX, Section 14-9-10 et seq . of
the Weld County Code. Additionally, audible noise levels were modeled for the Project
and are expected to be below 46 dBA (roughly comparable to a conversation in the
home) at the edge of the 230-kV right-of-way in rainy conditions, and below 21 dBA
(roughly comparable to a whisper) at the edge of the 230-kV right-of-way in rainy
conditions. See Section 21 -3-330. B. 15—Hydrologic, Atmospheric, Geologic, Pedologic,
Biotic, Visual, and Noise Impacts.
B. The operation of the USES shall comply with the air quality regulations promulgated by the
Colorado Air Quality Control Commission.
Construction of the Project is not expected to contribute negatively to the air quality
status in the area. There would be no long-term air quality effects associated with routine
operation and maintenance of the proposed transmission lines and substations. See
Section 21 -3-330. B. 12—Air and Water Pollution Impacts and Control Alternatives, Air
Pollution Impact and Control.
C. The operation of the USES shall comply with the water quality regulations promulgated by
the Colorado Water Quality Control Commission.
There would be no direct impacts to water quality associated with the regular operation or
maintenance of the transmission lines and substations. See Section 21 -3-330. B. 12—Air
and Water Pollution Impacts and Control Alternatives, Air Pollution Impact and Control.
D. The USES shall comply with the following lighting standards:
1 . Sources of light, including light from high-temperature processes such as combustion
or welding, shall be shielded so that light rays will not shine directly onto ADJACENT
properties where such would cause a nuisance or interfere with the USE on the
ADJACENT properties; and
No lighting would be required for transmission line structures. Lighting will be
installed throughout the substation yards and mounted on the exterior of the electric
equipment enclosures. However, lights are generally only on in emergency situations
when maintenance is required during low light conditions. Substation lighting would
not cause a nuisance on adjacent properties.
29
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
2. Neither direct nor reflected light from any light source may create a traffic hazard to
operators of motor vehicles on PUBLIC or private STREETS and no colored lights may
be used which may be confused with or construed as traffic control devices.
No lighting would be required for transmission line structures. Lighting will be
installed throughout the substation yards and mounted on the exteriors of the electric
equipment enclosures. However, lights are generally only on in emergency situations
when maintenance is required during low light conditions. Substation lighting would
not cause a traffic hazard on county roads and no colored lights would be used .
E. The USES shall not emit heat so as to raise the temperature of the air more than five
degrees (5°) Fahrenheit at or beyond the LOT line.
The proposed transmission lines and substations would not raise the temperature of the
air more than five (50) degrees Fahrenheit at or beyond the lot line. See Section 21 -3-
330. B.5.g—Hazards and Emergency Procedures.
F. Property shall be maintained in such a manner that grasses and weeds are not permitted to
grow taller than twelve (12) inches. In no event shall the property owner allow the growth of
NOXIOUS WEEDS.
Tri-State's Environmental Protection Measures for Construction Projects (Appendix C)
contains a description of revegetation and noxious weed control.
G. Any off-site and on-site improvements agreement shall be made in conformance with the
County policy on collateral for improvements. (Weld County Codification Ordinance 2000-1 ;
Weld County Code Ordinance 2007-1 )
Not applicable.
23-2-260 . APPLICATION REQUIREMENTS.
A. The purpose of the application is to give the petitioner an opportunity to demonstrate
through written and graphic information how the proposal complies with the standards of
this Chapter. The following supporting documents shall be submitted as a part of the
application except for those items determined by the Director of Planning Services, in
writing, or the Board of County Commissioners, on the record, to be unnecessary to a
decision on the application:
1 . A statement which explains that the proposal is consistent with Chapter 22 of this Code
and any other applicable code provision or ordinance in effect.
The Weld County Code, Chapter 22, Comprehensive Plan , has been reviewed and

Weld County USR and 1041 Application
2. A statement which explains that the proposal is consistent with the intent of the district
in which the USE is located.
The portions of the Project located in unincorporated Weld County are within the
Agricultural Zone District. Major facilities of public utilities are uses that are allowed
by special review within the Agricultural Zone District. See Section 21 -3-330. B.5.a—
Present Use and Zoning .
3. A statement which explains that the USES which would be permitted will be compatible
with the existing surrounding land USES.
The area is largely used for agricultural purposes, oil and gas development, and rural
residences. There are numerous existing transmission line corridors in the area
including one that largely parallels the Greenhouse—Colfer transmission line. This
Project would be compatible with the existing surrounding land uses. See Section 21 -
3-330. B.5.m—Existing Land Uses of All Properties Adjacent to Parcel.
4. A statement which explains that the USES which would be permitted will be compatible
with the future DEVELOPMENT of the surrounding area as permitted by the existing
zone and with future DEVELOPMENT as projected by Chapter 22 of this Code and any
other applicable code provision or ordinances in effect, or the adopted MASTER PLANS
of affected municipalities.
This use is consistent with the future development of the surrounding area as
permitted by the existing zoning and as projected by Chapter 22 of this Code. See
Section 21 -3-330. B.5.a—Present Use and Zoning . The area surrounding the
Greenhouse—Colfer transmission line located within the City of Fort Lupton is zoned
Industrial; the remaining substations and transmission lines are located in
unincorporated Weld County in the Agricultural zone.
5. A statement which explains that the application complies with Article V of this Chapter
if the proposal is located within any Overlay District Area identified by maps officially
adopted by the COUNTY.
A portion of the Milton—South Kersey transmission line and all of the Milton
Substation is within an Overlay District Area, as defined in Article V for the Greeley-
Weld County Airport. The portion of the transmission line within the Overlay District
Area is approximately 29,000 feet from the end of the runway at its nearest point. The
Milton Substation is approximately 43,000 feet from the end of the runway. Tri-State
coordinated with the Operations Coordinator at the Greeley-Weld County Airport,
Cooper Anderson , and was informed that the proposed project south of Kersey
should not interfere with the operations of the airport. However, an official review will
occur through the Project's Federal Aviation Administration (FAA) filing.

6. A statement which explains that if the USE is proposed to be located in the A
(Agricultural) Zone District, the applicant has demonstrated a diligent effort has been
made to conserve prime agricultural land in the locational decision for the proposed
USE.
Numerous soil types along the transmission lines are designated as Prime Farmlands
or Farmlands of Statewide Importance. However, placement of the transmission line
support structures would not preclude the use of farmland under the suspended
transmission lines. Approximately 32 acres of the right-of-way is considered Prime
Farmland , if Irrigated or Drained. There are approximately 71 acres of Farmlands of
Statewide Importance within the 150-foot right-of-way (Figure 2). However, only a
small portion of the soils in the right-of-way would be disturbed for the Project (less
than 1 acre of permanent disturbance for the transmission lines). Approximately 35%
of the Golfer Substation is considered Farmland of Statewide Importance and 10% of
the Rattlesnake Ridge Substation is considered Prime Farmland if Irrigated.
However, the Golfer Substation is not currently being used for agriculture because of
oil and gas development and the parcel proposed for the Rattlesnake Ridge
Substation is proposed for multiple oil and gas facilities, exclusive of the substation .
See Section 21 -3-330. B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic,
Visual, and Noise Impacts.
7. A statement which explains that there is adequate provision for the protection of the
health, safety and welfare of the inhabitants of the NEIGHBORHOOD and the COUNTY.
All Tri-State electric facilities are designed , constructed , operated, and maintained to
meet or exceed all applicable standards of design and performance set forth in the
National Electrical Safety Code (NESC 2012). Health and safety concerns associated
with the Project, therefore, would be limited largely to electromagnetic fields (EMF)
from the transmission lines. EMF was modeled for the project based on typical and
peak loads, from the proposed transmission lines, and is described in Section 21 -3-
330. B.5.g—Hazards and Emergency Procedures.

The names and addresses of all owners of surface property within 500 feet of the centerline
of the proposed corridor are provided in Appendix G.
21 -3-330.B.2.b—Access to the Protect Area
Right-of-way agreements include 150-foot easements purchased from landowners along the
transmission alignment. Tri-State would acquire easements for the transmission lines prior to
construction.
Only a small portion of the transmission line right-of-way would be disturbed for structure
installation and vehicle access. The majority of the proposed right-of-way can be accessed
from existing county roads (Figure 2) and via cross-country travel. Where construction of new
roads is required to gain access to sites where the poles would be erected, Tri-State will
design the roads to minimize impacts to resources while allowing access by construction and
maintenance vehicles. The location of proposed new roads will be provided to the County
with the final plat.
Existing oil and gas access roads would be used to access the staging areas located off of
County Roads 18 and 43. The substation access roads would be used to access the staging
areas at the Colfer and South Kersey Substations. Tri-State will submit Access Road Permit
applications where required and will comply with all County design standards.
21 -3-330.B.2.c—Real Property Interests

The portion of the Project located in unincorporated Weld County is zoned Agricultural. This
zoning is intended to provide areas for the conduct of agricultural activities and activities
related to agriculture and agricultural production without interference of other incompatible
land uses. Land use in the Project vicinity is primarily agricultural , residential, and energy
development (oil and gas facilities). Land cover in the Project area is primarily grassland,
weeds, and herbaceous vegetation (Figure 6). Existing land use is presented in Figure 7.
21 -3-330.B.5.b—d—Map Extent
Figure 2 illustrates all existing transmission lines of 115-kV or greater within two miles of the
Project site.
21 -3-330.B.5.e—Type of Facility
The Project would involve construction of approximately 30.5 miles of new 230-kV
transmission lines originating at the Greenhouse Substation and terminating at the South
Kersey Substation . United Power would construct the distribution lines (< 115-kV), which are
considered a use allowed by right in the Agricultural Zone District, and not included in this
permit application . The new transmission lines would be constructed on steel structures
within a 150 foot right-of-way. The transmission line would consist of approximately 160-270
structures, with conductors and phase wires, a shield wire, and an optical ground wire for
internal Tri-State communications.
The project will also include three new substations:
Colfer Substation-115/69/13.2-kV substation located on lands to be owned by Tri-State. The
Colfer Substation will include a 115-kV six breaker ring bus, expandable to an inverted
breaker and a half, one 115/69/13.8kV 100 megavolt ampere (MVA) transformer, one
115/13.2kV 40 MVA transformer, and four 115-kV transmission line bays.
Rattlesnake Ridge Substation-115/69/13.2-kV substation located on lands leased by United
Power. The Rattlesnake Ridge substation will include a ring bus (expandable to a breaker
and a half) with 4x 115-kV breakers, a single 115/13.2kV 40 MVA transformer, and one
115/69/13.8kV 100 MVA transformer.
Milton Substation-230/115-kV substation located on lands to be owned by Tri-State. The
Milton Substation will include one 230/115-kV 300 MVA transformer, three 230-kV breakers
and three 115-kV breakers, expandable to an ultimate arrangement that will include a 115-kV
inverted breaker and a half and a 230-kV inverted breaker and a half. The substation will
allow for future expansion and additional 230-kV, 115-kV, or distribution level connections.
There will initially be a 230-kV connection from the Phase I Greenhouse Substation and a
49
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
115-kV connection to a future substation located just east of the Milton Substation (across
County Road 49) called the Neres Canal Substation . The Neres Canal Substation would be
permitted by an oil and gas operator as part of a proposed gas plant.
Site preparation at all of the substations will include grading , fencing , grounding , and
construction foundations. The addition of equipment to the South Kersey substation would
include a breaker, line position , and associated equipment (all located inside the existing
fence boundary).
The Project also includes construction staging areas used for the duration of construction to
store equipment and stage construction located near the Davis Substation on County Road
18, near the Rattlesnake Ridge Substation on County Roads 43 and 30, and at the proposed
Colfer and South Kersey Substations. Each staging area will have two construction trailers
on-site for approximately 19 months, multiple storage containers, and other associated
equipment.

21 -3-330. B. 5.g—Hazards and Emergency Procedures
The purpose of the proposed Project is to transform and transmit electricity. The greatest
danger from a transmission line is direct contact with electrical conductors. Accordingly,
extreme caution must be exercised when operating high-profile vehicles and equipment near
the Project facilities. The conductors are supported by insulators mounted on grounded poles
to prevent arcing (which could start a fire). Tri-State prohibits storage of flammables,
construction of flammable structures, and other activities that have the potential to cause or
provide fuel for fires on its easements and rights-of-way. There are no explosive substances
associated with the proposed transmission lines or substations. All Tri-State electric facilities
are designed, constructed, operated , and maintained to meet or exceed all applicable
standards of design and performance set forth in the NESC (NESC 2012).
Post-construction, the proposed transmission lines and substations would be unmanned and
controlled remotely by Tri-State. The proposed lines are designed with overhead ground
wires and grounded towers to protect the system from becoming damaged by lightning .
Transmission line poles and conductors occasionally may be hit by lightning ; therefore, the
area near towers and other tall objects (e.g. , trees) should be avoided during thunderstorms.
Health and safety concerns associated with the Project, therefore, would be limited largely to
EMF from the transmission lines and substations. Electric fields are caused by voltage on an
object, such as the voltage on conductors connected to an energized substation . Magnetic
fields are produced when an electrical current flows through a conductor. EMF extends
outward from transmission line conductors and decreases rapidly with distance from the
transmission line. This concept of prudent avoidance was considered in the siting , proposed
construction, and operation of this facility.
The expected levels of EMF for the proposed transmission lines were modeled for the Project
and were found to be below 150 milligauss (mG), as required by the Colorado Public Utilities
Commission (PUC) (Rules 3206(e) and (f)). Levels are predicted to be below 50 mG at the
edge of the 230-kV right-of-way. These levels are similar to magnetic fields generated by
common household appliances, power tools, and office equipment (Table 7).
The Colorado PUC requires a utility to include the concept of prudent avoidance with respect
to planning , siting , construction , and operation of transmission facilities. Prudent avoidance is
the striking of a reasonable balance between the potential health effects of exposure to
magnetic fields and the cost and impacts of mitigation of such exposure, by taking steps to
reduce the exposure at reasonable or modest cost. Such steps might include, but are not
limited to: ( 1 ) Design alternatives considering the spatial arrangement of phasing of
conductors: (2) Routing lines to limit exposures to areas of concentrated population and
group facilities such as schools and hospitals; (3) Installing higher structures; (4) Widening
right-of-way corridors; and (5) Burial of lines. This Project utilizes a delta design conductor
configuration and also maintains suitable distances from sensitive group receptors like
schools and hospitals.

* Dash (—) means that the magnetic field at this distance from the operating appliance could not be distinguished
from background measurements taken before the appliance had been turned on.
** Some appliances produce both 60-Hz and higher frequency fields. For example, televisions and computer screens
produce fields at 10,000-30,000 Hz (10-30 kHz) as well as 60-Hz fields.
*** Microwave ovens produce 60-Hz fields of several hundred milligauss, but they also create microwave energy
inside the appliance that is at a much higher frequency (about 2.45 billion hertz). We are shielded from the higher
frequency fields but not from the 60-Hz fields.

Numerous scientific studies have been conducted to better understand whether there is a
possibility that EMF causes disease. The consensus of scientists familiar with these studies
is that no significant risk to humans from long-term exposure to EMF has been established .
Tri-State remains sensitive to the EMF issue and responds promptly and accurately to
inquiries with currently available information . As corporate policy, Tri-State has adopted
programs to ensure that its electric facilities are designed , constructed, and operated to
minimize, to the extent prudent and practicable, the level of EMF that is created . Tri-State's
position statement on EMF health effects is included as Appendix B.
Environmental Hazards
Enclosed containment would be provided for all trash . All construction waste, including trash
and litter, garbage, other solid waste, petroleum products, and other potentially hazardous
materials would be removed from the site and transported to a disposal facility authorized to
accept such materials. There would be no significant amount of hazardous materials stored in
the Project area.
Construction, operation , and maintenance activities would comply with all applicable federal,
state, and local laws and regulations regarding the use of hazardous substances. The only
hazardous chemicals expected to be used on site are those found in diesel fuel , gasoline,
coolant (ethylene glycol), and lubricants in machinery. Hazardous materials would not be
drained onto the ground or into streams or drainage areas. In its contract with the
construction contractor, Tri-State would specify that it will hold a required pre-construction
meeting with the contractor to ensure all applicable laws and Tri-State's procedures would be
followed. Tri-State's Project Environmental Protection Measures for Construction Projects are
attached as Appendix C.
Although the transmission lines would be inspected annually, emergencies may occur. If
there were an issue, appropriate field crews and engineering personnel would be notified by
telephone or radio and they would undertake the required procedures to correct the problem
and restore facilities to normal operations.

21 -3-330. B.5.n—Present Zone and Overlay Zones
A portion of the Milton—South Kersey transmission line and all of the Milton Substation is
within an Overlay District Area, as defined in Article V for the Greeley-Weld County Airport.
The portion of the transmission line within the Overlay District Area is approximately 29,000
feet from the end of the runway at its nearest point. The Milton Substation is approximately
43,000 feet from the end of the runway. Tri-State coordinated with the Operations
Coordinator at the Greeley-Weld County Airport, Cooper Anderson , and was informed that
the proposed project south of Kersey should not interfere with the operations of the airport.
However, an official review will occur through the Project's FAA filing .
The transmission line from the Greenhouse Substation to the Colfer Substation , as well as
the Milton—South Kersey route, will require submittal of an application with FAA for a
"Determination of No Hazard to Air Navigation", due to its proximity to the Platte Valley
Airpark and the Easton-Valley View Airport, respectively. Tri-State will receive FAA clearance
prior to construction of these transmission lines.

21-3-330.B. 6—Natural and Socioeconomic Environmental Constraints
Affecting Site Selection and Construction
A Transmission Routing Study was completed for the Study Area (Appendix A) to help
determine potential routes for the Project. Detailed routing objectives are provided in Table 8
below, but generally included the following considerations:
❑ Length following existing linear features
❑ Number of residences in proximity
❑ Agricultural uses (e.g. center pivots)
Total line length between substations
,J Engineering factors (e.g . airports, stream crossings)
❑ Property lines
Proximity to wells and other oil and gas facilities
Table 8: Routing Objectives
Land Use Objectives
Avoid oil and gas flare and vent facilities by 75 feet for height clearance
Avoid gas pipelines by 75 feet. Avoid gas and water wells by 200 feet
Parallel existing transmission lines where possible, while maintaining appropriate clearance
Minimize number of transmission line crossings
Favor routing transmission line through areas with existing and future land uses that are compatible with
62
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
Table 8: Routing Objectives
transmission lines such as industrial, commercial, and agricultural land uses. Avoid areas with existing
and future land uses that are not compatible such as residential developments and high density land
use
Where they exist and are not constrained by crowding, parallel existing linear corridors (roads and
transmission lines)
Avoid occupied structures and other buildings
Avoid homes and buildings, and other industrial structures such as oil and gas wells, so that the ROW is
kept clear of existing structures
Avoid impacts to local airports, both private and public
Transportation Objectives
Favor paralleling existing state highways and county and local roads where possible
Land Cover Objectives
Transmission line spans are approximately 700 feet to 800 feet; therefore, avoid surface water or other
land features such as ditches that are greater than 800 feet in width that cannot be spanned
Minimize impacts to sensitive resources that exist in wetlands by spanning wetlands or routing around
wetlands or through careful pole placement
Existing Utility Infrastructure Objectives
Assess feasibility of routing along existing transmission and distribution lines and existing pipelines
Cultural and Historic Resources Objectives
Avoid potential degradation of National Register of Historic Places (NRHP)-listed sites by routing
transmission line away from such sites
Work with local county and municipalities to identify culturally sensitive landmarks or sites and avoid
routing transmission line within these sites
Biological Resources Objectives
Reduce potential impacts to sensitive species habitat
Minimize impacts to avian species by avoiding nesting areas
Based on the comparative analysis and stakeholder input, the preferred routes were
selected . The preferred routes minimize impacts to residences and current land use.
21-3-330.B. 7—Natural and Socioeconomic Environmental Impacts from
Construction of the Electric Transmission Line (satisfies 21-3-330. C. 2.a)
Land Use
Land use along the proposed transmission line route would be minimally impacted and would
continue to include agriculture, residential use, and oil and gas activities. The Weld County
Code, Chapter 22, Comprehensive Plan , has been reviewed and the proposed transmission
lines are consistent with the intent of the Comprehensive Plan , including land use,
environmental resources, and natural resources.
The proposed transmission lines would be located in an area that is zoned Agricultural.
Although the transmission lines are not an agricultural use, it is a land use commonly located
in agricultural areas and does not conflict with the goals outlined in the Comprehensive Plan .
Careful site planning would be developed with only a localized loss of agricultural land
quality. Ground disturbance generally would be limited to an area of approximately 100
63
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
square feet around each pole (10 feet x 10 feet). Although the route crosses over a number
of center pivots, agricultural productivity would be minimally impacted as a result of the
Project due to the ability of transmission lines to span the pivots. The long-term presence of
the numerous existing transmission lines and continued agricultural, residential, and oil and
gas development in the area provide an example of the complementary nature of the uses.
Transportation Impacts (satisfies 21 -3-330.C.2 .g)
Approximately 55 construction workers would be employed during the course of the
approximately 11 -month construction period . The maximum number of construction workers
at any one time would be approximately 55; however, the workers would likely be dispersed
along the right-of-way. Table 9 lists the personnel and equipment for each phase of
construction. Table 10 lists the weight of construction vehicles.
After construction , the Project would generate infrequent trips to the transmission lines and
substations during operation ; the lines would be inspected annually and occasionally for
maintenance.
No adverse effects on county roads are anticipated . Tri-State would work with the Weld
County Public Works Department to determine the appropriate access to the construction
area. All mobile construction equipment would be certified to operate on Interstate highways.
There may be short periods of time when traffic would be halted on County Roads to allow
construction vehicles to enter and exit the construction area. No improvements to Weld
County roads would be required.
Construction of the transmission lines and substations may coincide with construction of the
Weld County Road 49 expansion . Tri-State is working closely with the Public Works
Department to ensure that the Projects can be completed safely with minimal impacts to
traffic and landowners.

Socioeconomic Impacts ;satisfies 21 -3-330.C.2.g and 21 -3-330.C.3.a)
The communities nearest to the Project area are Fort Lupton , Hudson , and Kersey. Larger
nearby cities include Loveland, Greeley, Longmont and Thornton. It is anticipated that the
Project would have a small beneficial impact to the local economies of these towns and the
larger metropolitan cities. Construction contractors, regardless of origin, would likely spend
some money in these communities for fuel, food , or other supplies. During the construction
period , the local economy may see a small influx of dollars and a small increase in sales tax
revenue. The footprints of the proposed structures would be the only land removed from
current use. Land between the transmission structures would remain available for farming,
grazing , or other operations that do not interfere with safe and reliable operation of the
transmission lines.
The Project area is located within District 3 of the Weld County Sheriff's Department and is
within the jurisdiction of the following Fire Protection Districts (FPD):
Fort Lupton FPD
Hudson FPD
65
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
Platteville—Gilcrest FPD
SE Weld FPD
Platte Valley FPD
La Salle FPD
Greater Brighton FPD
Public roads are maintained by the Weld County Department of Public Works and the City of
Fort Lupton . The nearest hospital to the southern side of the Project area is in the City of
Longmont (Longmont United Hospital) and the nearest hospital to the northern side of the
Project area is in the City of Greeley (Northern Colorado Medical Center). None of these
services is expected to be affected, unless emergency situations occur.
There are no adverse socioeconomic impacts associated with the Project. The Project would
generate additional tax revenue for Weld County. This Project is not inconsistent with the
Economic Development Goals and Policies described in the Weld County Comprehensive
Plan (Weld County 2008).
Discussion of Impacts on Additional Resources Including Significant Environmentally
Sensitive Factors (satisfies 21 -3-330.C.2c and 21 -3-330.C.2e)
Vegetation Including Marshlands and Wetlands
The Project area is characterized by agricultural lands, oil and gas development, and
residential use. The surrounding vegetation is primarily disturbed grassland . Permanent
removal of vegetation would occur at structure sites and substations. Construction would
occur primarily in areas that have been previously disturbed , and impacts to native vegetation
communities are expected to be minimal. Most access would be overland or along existing
roads and minimal vegetation would be disturbed from roads.
No drainages or wetlands would be impacted by the transmission lines or substations.
Figure 8 presents a map of water resources within the Project area.
Wildlife and Critical Wildlife Habitat
The Project area is likely to support a variety of common wildlife such as coyote, fox, skunk,
rabbits, and various birds. There is no designated critical wildlife habitat in the vicinity of the
project although suitable habitat may exist for the state-listed Western burrowing owl.
Prior to construction, Tri-State will conduct surveys for migratory birds and Western
Burrowing Owls (in prairie dog towns in the vicinity of the transmission lines and substations).
If any nests for migratory birds or any listed species are found , appropriate construction
timing limitations will be enforced, as feasible, according to Colorado Parks and Wildlife
(CPW) recommendations. Where timing limitations or setback cannot be applied due to
timing constraints, other alternative mitigation measures would be considered and vetted with
CPW . If any federally-listed species are found, Tri-State will consult with the U . S. Fish and
Wildlife Service (USFWS) regarding avoidance and mitigation.

To preclude avian electrocutions and minimize collision risk, Tri-State would incorporate
Avian Protection Plan (APP) standards developed by the Avian Power Line Interaction
Committee (APLIC 2006) and the APP guidelines (APLIC and USFWS 2005) to protect birds
on power lines, as well as NESC-specified electric conductor clearances.
Project impacts to wildlife are expected to be minimal and limited to temporary disturbance
from construction activities.
Special Status Species
Federal and state-listed threatened or endangered species that occur in the Project area are
listed in Table 11 .

The Mexican Spotted Owl is known to occur in the southwestern U .S. with the main
populations inhabiting Arizona and New Mexico. The Mexican Spotted Owl prefers canyon
habitat consisting of mixed-conifer, pine-oak, and riparian forest. This habitat is not present in
the Project area. Therefore, Mexican Spotted Owls are unlikely to be impacted by the Project.
The Preble's meadow jumping mouse is a federally threatened species. This species inhabits
riparian areas and adjacent uplands. Preferred riparian habitat includes mixed vegetation
types where dense herbaceous or woody vegetation occurs near the ground level and where
available open water exists during their active season. Presence of this species in the Project
area is highly unlikely. There is no designated critical habitat for Preble's meadow jumping
mouse in Weld County.
69
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
The Ute ladies'-tresses orchid and Colorado butterfly plant are federally threatened plant
species associated with floodplains and wet meadows. No suitable habitat occurs within the
Project area.
Although Bald and Golden Eagles are not federally listed species under the Endangered
Species Act, they have federal protections under the Bald and Golden Eagle Protection Act
and the Migratory Bird Treaty Act. Eagles are found throughout the continuous U .S. and
Alaska, and occupy a very wide range of habitat. For nesting , they most frequently use cliffs
but will also nest in trees. Pre-construction surveys would be conducted for raptors to identify
any active nests and appropriate timing restrictions would be implemented to avoid impacts
to the Bald and Golden Eagles.
In addition to federally listed species, state-listed species that could occur in or near the
Project area include Plains Sharp-tailed Grouse, Mountain Plover, Western Burrowing Owl,
Swift Fox, and Ferruginous Hawk.
The Plains Sharp-tailed Grouse is listed as endangered in Colorado. The bird formerly nested
over much of the northern two-thirds of the eastern prairie, but the present population
consists of only a few hundred birds in Douglas County (CPW 2010). No impacts to Plains
Sharp-tailed Grouse are expected.
The project area is considered overall range for swift fox, which is a state-species of special
concern. As with other terrestrial mammal species in the area, impacts to swift fox are
expected to be minimal and primarily consist of temporary disturbance from construction
activities. Swift fox could be temporarily displaced during construction of the substations and
transmission lines, but animals in the area are likely habituated to human activity due to
residential development, agriculture, and oil and gas activities.
The Mountain Plover is a state-species of special concern and occurs in Weld County. More
than half of the world's population nests in the state, east of the Project area in the Pawnee
National Grasslands. Mountain plovers inhabit prairie grasslands, arid plains and fields.
Nesting areas include grasslands grazed by prairie dogs and cattle, and overgrazed tallgrass
and fallow fields. Presence or absence surveys for Mountain Plovers will be conducted prior
to construction in areas identified as suitable habitat. If any nests are found, appropriate
construction timing limitations will be implemented to avoid impacts to the Mountain Plover.
The Western Burrowing Owl is a state-threatened species and could occur in the Project
area. In northeastern Colorado, burrowing owls are typically associated with prairie dog
colonies. Burrowing owls can excavate their own burrows, but they usually depend on
burrows that have been started by colonially burrowing mammals, especially ground squirrels
and prairie dogs. Pre-construction surveys will be conducted in prairie dog towns. If Western
burrowing owls are encountered , timing restrictions will be implemented to avoid impacts to
this species.
70
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
The Ferruginous Hawk is a state-species of special concern in Colorado, and occurs year-
round in the state. It is a common winter resident on the eastern plains in open grasslands
and shrub steppe communities. Ferruginous Hawks nest in flat, rolling or rugged terrain in
open areas, cliffs or rock outcrops, or isolated trees in grasslands. Pre-construction surveys
will be conducted for raptors and if nests are encountered construction timing will be
implemented to avoid impacts to this species.
Unique Areas of Geologic, Historic, or Archaeological Importance
Tri-State will conduct a Class I archaeological database search of the Project area, as well as
a Class III pedestrian survey on properties where survey permission has been granted and
where significant disturbance has previously not occurred. Any sites found to be eligible for
listing on the NRHP will be spanned and avoided by the Project. There are no areas of
geologic importance in the vicinity of the project.
Vested Water Rights
The Project would have no impacts on vested water rights. Construction water and water to
suppress dust during construction activities would be trucked into the area.
21-3-330.B. 8—Long-Term Effects upon Physical and Socioeconomic
Development
The proposed Project would not have any adverse effects on physical or socioeconomic
development of the area.
21-3-330.B. 9—Mitigation of Adverse Impacts and Maximization of
Positive Impacts
Efforts would be made so the contour of the land and natural drainage patterns along the
right-of-way are not disturbed . If land contours and drainage patterns are disturbed, efforts
would be made to restore any negative effects. Because Weld County has a semi-arid
climate, revegetation can be difficult. As a result, disturbances to land surrounding the
construction area would be minimized. All practical efforts would be made to re-establish
native vegetation in the disturbed area. Tri-State's Environmental Protection Measures for
Construction Projects, included as Appendix C, addresses site reclamation of disturbed
areas.
21-3-330.8. 10—Non-Structural Alternatives
There are no non-structural alternatives that would accomplish the purpose and need for the
transmission lines and overall Project. If the Project is not constructed, Tri-State and its
Member's customers would be required to move their facilities or self-generate.
71
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
21-3-33O.B. 11-Structural Alternatives
Transmission routing alternatives were considered in addition to the Preferred routes. These
alternatives are discussed in more detail in the Alternatives to the Proposed Project section
(page 3).
21-3-330.B. 12—Air and Water Pollution Impacts and Control Alternatives
Air Pollution Impact and Control (satisfies 21 -3-330.C.2.d;
Construction would last approximately 11 months. Construction activities associated with the
proposed transmission lines and substations would generate less than significant amounts of
particulate matter from soil disturbances and diesel-powered equipment, and less than
significant amounts of carbon monoxide and the precursor pollutants to ozone formation from
tailpipe emissions. Any air pollutants generated would be widely dispersed across the Project
area, short term in duration , and minimized by the small scale of construction operations for
the substations, and excavating foundations for transmission structures. Air pollutants also
would be minimized through implementation of dust suppression and proper vehicle
maintenance. Therefore, Project construction is not expected to impact the air quality status
in the area. There would be no long-term air quality effects associated with routine operation
and maintenance of the proposed transmission lines and substations. Once construction
activities have been completed, but before vegetation has been re-established, some minor
amount of additional dust could occur. The generation of dust would be monitored by Tri-
State, and the appropriate action would be taken to control the dust and ensure that potential
wind erosion is minimized .
Weld County is an attainment area for all measured pollutants, including particulate matter
smaller than 10 micrometers in diameter (PMio). No air emissions would result from operation
of the transmission lines or substations.
Water Pollution Impacts and Control
There would be no direct impacts to water quality associated with regular operation or
maintenance of the transmission lines and substations. Drainage from the substations would
be directed towards detention pond(s) located on the substation properties. Drainage plans
will be prepared for the Rattlesnake Ridge Substation, the Milton Substation , and the Colfer
Substation . Prior to construction , a Storm Water Permit for Construction Activities would be
acquired from the CDPHE , where required .
21-3-330.B. 13—Design Alternatives: Access, Landscaping, and
Architecture
Access to the Project construction area would primarily be provided by existing roads and the
right-of-way along the transmission lines. Where construction of new roads is required to gain
access to sites where the poles would be erected, Tri-State will design the roads to minimize
impacts to resources while allowing access by construction and maintenance vehicles. The
access roads would not require architectural or landscape treatments.
72
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
21-3-330.B. 14—New or Upgraded Services
New or upgraded services are not applicable to, and not required for, this Project.
21-3-330.B. 15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic,
Visual, and Noise impacts
Biotic and atmospheric impacts are described above.
Hydrologic
Construction and maintenance of the transmission lines and substations would not
measurably impact surface water or groundwater quality. Additionally, there would be no
long-term impacts to surface water or groundwater hydrology as a result of construction or
operation of the Project. Project would not impact hydrologic flow of either surface water or
groundwater, nor would it affect groundwater recharge. Prior to construction, a Storm Water
Permit for Construction Activities would be acquired from the CDPHE, where required
Minimal water would be used during Project construction. Water for construction purposes,
including concrete foundations and dust control, would be brought in from off-site sources by
a construction water provider. The source of the construction water would be from either a
private well owned by the construction water company or from a municipality. No existing
water rights would be impacted, and there would be no long-term use of water. If water is
needed for revegetation around transmission structures or temporary access roads, the
construction water provider would supply the water.
No water would be required for the operation of the transmission lines or substations.
Geologic
Construction and operation of the electric transmission lines and substations would not alter
the geology of the Project area. The Project does not occur within a Geologic Hazard Area.
Pedologic
Appendix D includes a complete list of the soil map units that occur in the Study Area.
Figure 5 shows the linear extensibility, or soil shrink/swell potential, in the Study Area.
Shrink/swell potential of a soil is based on the change in length of an unconfined clod as
moisture content is decreased from a moist to a dry state. The classes of shrink/swell
potential are shown in Table 12. The majority of the soils in the Study Area have low
shrink/swell potential.
Table 12: Soil Shrink/Swell Classes
Class Value
Low 0-3%
Moderate 3-6%
High 6-9%
Very high > 9%
73
Southwest Weld Expansion Project Phase II
Weld County USR and 1041 Application
Figure 9A shows the soil erodibility based on factor K within the Project area. The factor K is
a measurement of the soil's susceptibility to sheet and rill erosion by water; it is calculated as
a function of an average diameter of the soil particles. Factor K is one of six factors used in
the Revised Universal Soil Loss Equation to predict annual rate of soil loss in tons per acre
per year. Factor K values range from 0.02 to 0.69, with higher values indicating higher losses.
For the purpose of this report, soil K factors would be classified based on Table 13.
Table 13: Soil Erodibility Classes
Class Factor K Value
Low 0.05-0.2
Moderate 0.21 -0.4
High > 0.4
According to the NRCS Soil Survey of the Northern Part of Weld County (Appendix D), the
majority of the soils, including those found at the substations have low to moderately
erodibility. Soil erodibility by wind is shown on Figure 9B. Soils that are highly erodible by
wind occur throughout the Project area. EPMs described in Appendix C are expected to
mitigate impacts.
There are no data sources available that evaluate subsidence hazard in the Study Area.
However, there are no mines in the vicinity of the Study Area, which may increase the risk of
soil subsidence.
Numerous soil types along the transmission lines are designated as Prime Farmlands or
Farmlands of Statewide Importance. However, placement of the transmission line support
structures would not preclude the use of farmland under the suspended transmission lines.
Approximately 32 acres of the right-of-way is considered Prime Farmland , if Irrigated or
Drained . There is approximately 71 acres of Farmlands of Statewide Importance on the 150-
foot right-of-way (Figure 2). However, only a small portion of the soils in the right-of-way
would be disturbed for the Project (less than 1 acre of permanent disturbance).
Approximately 35% of the Golfer Substation is considered Farmland of Statewide Importance
and 10% of the Rattlesnake Ridge Substation is considered Prime Farmland if Irrigated .
However, the Golfer Substation is not currently being used for agriculture because of oil and
gas development and the parcel proposed for the Rattlesnake Ridge Substation is proposed
for multiple oil and gas facilities, exclusive of the substation .

The Project would not adversely affect any of the soil types within the Study Area.
Construction of the project would cause some localized soil compaction and increase the
potential for soil erosion . Long-term effects associated with soil erosion and compaction
would be minimized or negated though use of EPMs (Appendix C).
Noise
The Project would be constructed and maintained in accordance with Colorado Revised
Statutes 25-12-101 et seq. (Noise Abatement) and Article IX, Section 14-9-10 et seq . of the
Weld County Code. However, corona may result in audible noise being produced by the
transmission lines. Corona is the electrical ionization of the air that occurs near the surface of
the energized conductor due to very high electric field strength . The amount of corona
produced by a transmission line is a function of the voltage of the line, the diameter of the
conductors, the locations of the conductors in relation to each other, the elevation of the line
above sea level, the condition of the conductors and hardware, and the local weather
conditions. Irregularities (such as nicks and scrapes on the conductor surface or sharp edges
on suspension hardware) concentrate the electric field at these locations and thus increase
the electric field gradient and the resulting corona at these spots. Raindrops, snow, fog , and
condensation accumulated on the conductor surface are also sources of surface irregularities
that can increase corona.
Audible noise levels were modeled for the Project and are expected to be below 46 dBA
(roughly comparable to a conversation in the home) at the edge of the 230-kV right-of-way in
rainy conditions, and below 21 dBA (roughly comparable to a whisper) at the edge of the 230-
kV right-of-way in normal conditions.
Visual
The Project is not expected to significantly affect the aesthetics of the area. There is
extensive oil and gas development in the area, as well as existing electrical infrastructure
including transmission lines.
21-3-330.B. 16-Surface and Subsurface Drainage
Subsurface drainage would not be impacted by the proposed transmission lines. There would
be no alteration in the pattern or intensity of surface drainage as a result of construction or
operation of the transmission lines. Drainage from the substations would be directed towards
detention pond(s) located on the substation properties. Drainage plans will be prepared for
the Rattlesnake Ridge Substation , the Milton Substation, and the Colfer Substation . A range
of measures ensuring the Project does not impact water quality is listed in Appendix C; prior
to construction , a Storm Water Permit for Construction Activities would be acquired from
CDPHE, where required.

TOPIC
No. STANDARD ENVIRONMENTAL PROTECTION MEASURES
General
G-1 The contractor shall comply with all federal, state, and local environmental laws, orders,
and regulations. Prior to construction, all supervisory construction personnel will be
instructed on the protection of cultural and ecological resources.
G-2 Prior to construction , Tri-State shall discuss with the contractor areas of environmental
sensitivity within the Project area and , in particular, those areas where a monitor must be
present during construction.
Access Routes
AR-1 No construction activities will be performed during periods when the soil is too wet to
adequately support equipment and vehicles. If equipment or vehicles create ruts in excess
of 4-6 inches deep for a distance of 10 feet on native surface roads, the soil shall be
deemed too wet to adequately support construction equipment. If equipment or vehicles
create ruts in excess of 1 inch deep on graveled roads, the roads shall be deemed too wet
to support construction equipment.
AR-2 Only the minimum amount of soils and vegetation necessary for the maintenance of
access routes and the safe and reliable operation of the transmission line will be disturbed.
If excavation is necessary, topsoil will be conserved and reused as cover on disturbed
areas to facilitate re-growth of vegetation. Vegetation will be cleared from those areas
necessary to obtain adequate working width and turning radius space for maintenance
equipment and allow for the safe operation of the transmission line.
AR-3 Water bars on the access roads will be constructed as specified by Tri-State. Water bars
will be constructed to: 1 ) simulate the imaginary contour lines of the slope (ideally with a
grade of 1 to 2%); 2) drain away from the disturbed area; and 3) begin and end in
vegetation or rock, whenever possible. Tri-State to provide specification for water bar
construction.
Water turn-off bars or small terraces shall be installed across all temporary construction
access roads and trails on hillsides to prevent erosion and facilitate natural revegetation of
the trails.
Aesthetics
A-1 The contractor shall exercise care to preserve the natural landscape and shall conduct
construction operations so as to prevent any unnecessary destruction, scarring, or
defacing of the natural surroundings in the vicinity of the work. Except where clearing is
required for permanent works, approved temporary or permanent construction roads,
staging areas, or excavation operations, vegetation shall be preserved and protected from
damage by the contractor's construction operations and equipment.
A-2 The contractor shall minimize scarring, defacing, damage, or destruction of the natural
landscape resulting from construction operations. Any unnecessary or unauthorized
damage shall be repaired by the contractor to the satisfaction of Tri-State.
A-3 All construction materials, waste, and debris shall be removed from the project area in a
timely manner. Burning or burying of waste materials on the right-of-way or at the
construction site will not be allowed. All materials resulting from the contractor's clearing
operations shall be removed from the right-of-way.
A-4 Structures will be located and designed to conform with the terrain and with minimal visual
impacts whenever possible. Leveling and benching of the structure sites will be done to the
minimum necessary to allow structure assembly and erection.
Air Quality
AQ-1 The contractor shall utilize practicable methods and devices as are reasonably available to
control, prevent, and otherwise minimize atmospheric emissions or discharges of air
contaminants.
AQ-2 Possible construction-related dust disturbance shall be controlled by the periodic
application of water to all disturbed areas along the right-of-way and access roads.
C-1

TOPIC
No. STANDARD ENVIRONMENTAL PROTECTION MEASURES
AQ-3 Vehicles and equipment showing excessive emission of exhaust gases due to poor engine
adjustments or other inefficient operating conditions shall not be operated until corrective
adjustments or repairs are made.
AQ-4 Post seeding mulch will be utilized during reclamation activities to help reduce wind erosion
and blowing dust. The mulch/stabilization will be performed as soon as possible after
completion of project activities to minimize potential fugitive dust generation as
revegetation occurs.
Biological Resources
BR-1 Vegetation shall be preserved and protected from damage by construction operations to
the maximum extent practicable. Removal of brush and trees will be limited to those
necessary for access and construction. There will be no clear cutting within the right-of-
way unless specifically approved in writing by Tri-State.
BR-2 Disturbed areas where vegetation has been removed by construction activities to the
extent that the potential for soil erosion is increased to a detrimental level will be subject to
seedbed preparation techniques, reseeded with an approved seed mixture, and mulched
(if necessary) during a recognized planting season. Mulching shall be applied only to those
areas where potential erosion would prohibit vegetation establishment and growth .
BR-3 The contractor shall not cross any wetland and riparian areas (of or relating to, or located
on, the banks of a river or stream), except at designated locations designated by Tri-State
BR-4 On completion of the work, all work areas, except any permanent access roads/trails, shall
be regraded, as required, so that all surfaces drain naturally, blend with the natural terrain,
and are left in a condition that will facilitate natural revegetation, provide for proper
drainage, and prevent erosion.
BR-5 All disturbed areas, except the access route running surfaces, will be reseeded with seed
mixes as specified by Tri-State.
BR-6 All construction materials and debris shall be removed from the project area.
BR-7 To preclude avian electrocutions and minimize collision risk, Tri-State will incorporate
Avian Protection Plan (APP) standards developed by the Avian Power Line Interaction
Committee (APLIC 2006) and the APP guidelines (APLIC and USFWS 2005) to protect
birds on power lines, and NESC-specified electric conductor clearances.
Cultural Resources
CR-1 Prior to construction, all supervisory construction personnel will be instructed on protection
of cultural resources with reference to relevant laws and penalties, and the need to cease
work in the location if cultural resource items are discovered.
CR-2 Should any previously unknown historic/prehistoric sites or artifacts be encountered during
construction, all land-altering activities at that location will be immediately suspended and
the discovery left intact until such time that Tri-State is notified and appropriate measures
taken to assure compliance the National Historic Preservation Act and enabling legislation.
Fire Prevention/Control
FP-1 Construction vehicles shall be equipped with government-approved spark arresters.
FP-2 The contractor shall maintain in all construction vehicles a current list of local emergency

Hazardous Materials
HM-1 Tri-State shall comply with all applicable federal laws and regulations existing or hereafter
enacted or promulgated regarding toxic substances or hazardous materials. In any event,
Tri-State shall comply with the Toxic Substances Control Act of 1976, as amended (15
U .S.C. 2601 , et seq.) with regard to any toxic substances that are used, generated by, or
stored on the right-of-way or on facilities authorized under this right-of-way grant (See 40
Code of Federal Regulation (CFR), Part 702-799 and especially, provisions on
polychlorinated biphenyls, 40 CFR 761 . 1-761 . 193. ). Additionally, any release of toxic
substances (leaks, spills, etc.) in excess of the reportable quantity established by 40 CFR,
Part 117 shall be reported as required by the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, section 102b. A copy of any report required or
requested by any federal agency or state government as a result of a reportable release or
spill of any toxic substance shall be furnished to the authorized officer concurrent with the
filing of the reports to the involved federal agency or state government.
HM-2 No bulk fuel storage will occur within the public lands portion of the project right-of-way. All
fuel and fluid spills within this area will be handled in accordance with appropriate state
and federal spill reporting and response requirements. The contractor shall notify Tri-State
of any spills so appropriate notifications can be made to regulatory authorities.
HM-3 Any waste generated as a result of the proposed action will be properly disposed of in a
permitted facility. Solid waste generated during construction and periodic maintenance
periods will be minimal . All hazardous materials will be handled in accordance with
applicable local, state, and federal hazardous material statues and regulations.
Land Use
LU-1 All activities associated with the construction, operation, and maintenance of the
transmission line will take place within the authorized limits of the transmission line right-
of-way and access routes. Additional access routes or cross-country travel will not be
allowed outside of the authorized routes prior to review and approval by Tri-State.
LU-2 The contractor shall maintain all fences, brace panels, and gates during the construction
period. Any fence, brace panel, or gate damaged during construction will be repaired
immediately by the contractor to appropriate landowner or agency standards as
determined by the authorized officer.
LU-3 The contractor shall eliminate, at the earliest opportunity, all construction ruts that are
detrimental to agricultural operations and/or hazardous to movement of vehicles and
equipment. Such ruts shall be leveled, filled, and graded, or otherwise eliminated in an
approved manner. Damage to ditches, tile drains, culverts, terraces, local roads, and other
similar land use features shall be corrected as necessary by the contractor. The land and
facilities shall be restored as nearly as practicable to their original condition.
LU-4 Structure foundation holes will not be left open overnight and will be covered. Covers will
be secured in place and will be strong enough to prevent livestock, wildlife, or the public

Noxious Weeds
NW-1 To minimize introduction of noxious weed seed sources to the project area, the following
measures will be performed . All heavy equipment utilized during construction will be
washed prior to departure from the equipment storage facility. Washing of equipment prior
to transport from one work site to another is not recommended, as on-site washing of
equipment increases the chance of weed seed dispersal by drainage of water off of the
site, across an area greater than the size of the work site. Equipment will have
accumulations of mud `knocked off' instead. This method promotes containment of weed
seeds on the work site. All seed mixes and mulch used for reclamation activities will be
certified weed-free.
Soils and Geology
S-1 The contractor shall mitigate soils compacted by movement of construction vehicles and
equipment by 1 ) loosened and leveled harrowing or disking to approximate pre-
construction contours and 2) reseeding with certified weed-free grasses and mulched
(except in cultivated fields). The specific seed mix(s) and rate(s) of application will be
determined by Tri-State.
S-2 Movement of construction vehicles and equipment shall be limited to the right-of-way and
approved access routes.
S-3 Excavated material not used in the backfilling of poles shall be spread around each pole,
evenly spread on the access routes in the immediate vicinity of the pole structure, or
transported off site to a Tri-State-approved disposal location. Disturbed areas shall then be
regraded to approximate pre-construction contours and reseeded as specified in S-1 .
S-4 Topsoil will be removed, stockpiled, and re-spread at temporarily disturbed areas not
needed for maintenance access.
Traffic
T-1 The contractor shall make all necessary provisions for conformance with federal, state, and
local traffic safety standards and shall conduct construction operations so as to offer the
least possible obstruction and inconvenience to public traffic.
Water Quality and Erosion
WQ-1 Construction activities shall be performed by methods that prevent entrance or accidental
spillage of solid matter, contaminants debris, and other objectionable pollutants and
wastes into flowing streams or dry water courses, lakes, and underground water sources.
Such pollutants and wastes include, but are not restricted to, refuse, garbage, cement,
concrete, sanitary waste, industrial waste, radioactive substances, oil and other petroleum
products, aggregate processing tailings, mineral salts, and thermal pollution.
WQ-2 Dewatering work for structure foundations or earthwork operations adjacent to, or
encroaching on , streams or water courses shall not be performed without prior approval by
Tri-State and appropriate state agencies. Water and eroded materials will be prevented
from entering the streams or watercourses by constructing intercepting ditches, bypass
channels, barriers, settling ponds, or other approved methods.
WQ-3 Borrow pits shall be so excavated that water will not collect and stand therein. Before
being abandoned, the sides of borrow pits shall be brought to stable slopes, with slope
intersections shaped to carry the natural contour of adjacent, undisturbed terrain into the
pit or borrow area, giving a natural appearance. Waste piles shall be shaped to provide a
natural appearance.
WQ-4 Excavated material or other construction materials shall not be stockpiled or deposited
near or on stream banks, lake shorelines, or other water course perimeters where they can
be washed away by high water or storm runoff or can in any way encroach upon the water
source itself.

WQ-5 Waste waters from construction operations shall not enter streams, water courses, or other
surface waters without use of such turbidity control methods as settling ponds, gravel-filter
entrapment dikes, approved flocculating processes that are not harmful to fish,
recirculation systems for washing of aggregates, or other approved methods. Any such
waste waters discharged into surface waters shall be essentially free of settleable material.
Settleable material is defined as that material that will settle from the water by gravity
during a 1 -hour quiescent period.
WQ-6 A Storm Water Management Plan shall be developed, if required, to address all
construction and reconstruction activities. The plan shall conform with all U.S.
Environmental Protection Agency and Best Management Practices requirements.

Weld County USR and 1041 Application
Site-Specific Development Plan and Use by Special Review (USR) Questionnaire
1 . Explain, in detail, the proposed use of the property.
The proposed use of the property is described in the following sections of the Weld
County 1041 Permit Application : Project Description , Introduction , Purpose and Need,
and Proposed Action Sections.
2. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 22 of the Comprehensive Plan.
The Weld County Code, Chapter 22, Comprehensive Plan , has been reviewed and the
proposed substations and transmission lines are consistent with the intent of the
Comprehensive Plan, including Land Use, Environmental Resources, and Natural
Resources.
The proposed substations and transmission lines are located in the Agriculture Zone.
Although the transmission lines are not an agricultural use, it is a land use that is
commonly located in agricultural areas and does not conflict with the goals outlined in the
Comprehensive Plan. Careful site planning can be developed with only a localized loss of
agricultural land quality. Ground disturbance for transmission lines is generally limited to
the area immediately around the base of each pole. The Colfer and Rattlesnake Ridge
substations would occur on lands removed from agricultural use for oil and gas
development. Agricultural practices could continue on adjacent lands.
Impacts to environmental resources such as air, water, waste, noise, and public health
would be minimal and limited to the construction period (see Sections 21 -3-330. B.5.g ,
21 -3-330. B. 12, and 21 -3-330.B . 15). Mitigation practices described in Appendix C of this
Weld County 1041 Application would be implemented to minimize impacts to
environmental resources.
Natural resources such as sensitive wildlife areas, recreation areas, and mineral and
energy resources would not be impacted by the proposed Project. Impacts to and
proposed mitigation for sensitive wildlife are described in the Wildlife and Critical Wildlife
Habitat section and Appendix C of this Weld County 1041 Application . No parks, open
space or recreation areas are located near the Project. A number of oil and gas wells and
associated facilities occur in the vicinity of the proposed transmission lines and
substations. Detailed design of the transmission lines will ensure that poles are located to
avoid any impact on these facilities.

3. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 23 (Zoning) and the zone district in which it is located.
The proposed Project is located within the Agricultural Zone District. Major facilities of
public utilities may be constructed , operated , and maintained in the Agricultural Zone
District upon approval of a permit in accordance with the requirements and procedures
set forth in Article II , Division 4 of Chapter 23 of the Weld County Code. Major facilities of
a public utility are also subject to the provisions of section 23-4-420. This section of the
code states that the applicant shall have the burden of proof to demonstrate that there is
a need for the facility within the proposed area of service; this is discussed in the Purpose
and Need section of this Weld County 1041 Application .
4. What types of uses surround the site (explain how the proposed use is consistent
and compatible with surrounding land uses).
The area is largely used for agricultural purposes, oil and gas development, and rural
residences. There are numerous existing transmission line corridors in the area including
one that largely parallels the Greenhouse—Colfer transmission line. This Project would be
compatible with the existing surrounding land uses. There are a total of six total
residences within 200 feet of the Preferred transmission line routes and 21 residences
within 500 feet. There are no residences adjacent to the Colfer Substation . One
residence is located across County Road 49 from the Rattlesnake Ridge Substation , and
one residence is located on the same parcel as the Milton Substation . There are multiple
oil and gas wells and facilities, including pipelines, in the area as well.
5. Describe in detail, the following:
a. Number of people who will use the site
Following construction, no people would use this site, other than those performing
routine maintenance and monitoring the transmission lines and substations.
b. Number of employees proposed to be employed at this site
The maximum number of construction workers at any one time would be
approximately 55. The Project would generate infrequent trips to the transmission
lines and substations during operations with the line being inspected annually and for
occasional maintenance.
See Section 21 -3-330. B.7 of the Weld County 1041 Application for additional
information .

RE: Minor Changes to the Use by Special Review (USR) and 1041 Permit Application for Phase
II of the Southwest Weld Expansion Project
Mr. Ogle:
Tri-State Generation and Transmission Association, Inc. (Tri-State) is submitting this letter to
inform you of minor changes to the application submitted on July 23, 2015 for the Use by
Special Review (USR) and 1041 Permit Application for the Southwest Weld Expansion Project,
Phase II (Project). Based on ongoing planning and coordination with the County, landowners,
and other developers in the area, Tri-State is proposing the following changes to the application:
the modification of the maximum structure height to 140' up from 135 '; the addition of another
landowner; and a change in access for the Rattlesnake Ridge Substation. Each of these changes is
described below.
Section 23-2-260.C.6 (pages 36 — 38) and Figure 4 in the application describe the typical 230-kV
structure proposed for the Project. This structure has been changed slightly to better allow Tri-
State to maintain these structures now and into the future. The maximum height of the structure
will change from 135 ' to 140' to allow for greater spacing between the conductors to meet
current industry requirements for minimum approach distances. A revised Figure showing the
typical structure type is attached to this letter.
As the County is aware, there is extensive oil and gas development in this area of the County. In
order to accommodate a pipeline that was recently constructed along the proposed Milton —
South Kersey route, Tri-State shifted the line slightly to the west. This shift added an additional
landowner to the list of surface property owners. Mr. Larry Oster (Parcel No. 153073000049),
located in Township 4N, Range 64 West, Section 7, has since been informed of the Project and
has granted Tri-State survey permission on his property.
Throughout the development of the Project and in preparation of the 1041 and USR permit
application, Tri-State coordinated with the Weld County Public Works Department on their
proposed County Road 49 expansion. Access to the proposed Rattlesnake Ridge Substation was
initially proposed along County Road 30 in order to avoid conflicts with the County's expansion.
However, recent issues with the land rights related to the access off of County Road 30 have
required that Tri-State move its proposed access to County Road 49. The Public Works
Department would like Tri-State to share Access Point W-80, as identified in their Access

completion of project activities to minimize potential fugitive dust generation as re-vegetation
occurs.
Biological Resources
BR-1 Vegetation shall be preserved and protected from damage by construction operations to the
maximum extent practicable. Removal of brush and trees will be limited to those necessary for
access and construction There will be no clear cutting within the right-of-way unless specifically
approved in writing by Tri-State.
BR-2 Disturbed areas where vegetation has been removed by construction activities to the extent
that the potential for soil erosion is increased to a detrimental level will be subject to seedbed
preparation techniques, reseeded to an approved seed mixture, and mulched if necessary
during a recognized planting season . Mulching shall be applied only to those areas where
potential erosion would prohibit vegetation establishment and growth .
BR-3 The contractor shall not cross any wetland and riparian areas (of or relating to, or located on ,
the banks of a river or stream), unless at designated locations designated by Tri-State
BR-4 On completion of the work, all work areas, except any permanent access roads/trails, shall be
regraded , as required , so that all surfaces drain naturally, blend with the natural terrain, and
are left in a condition that will facilitate natural revegetation , provide for proper drainage and
prevent erosion .
BR-5 All disturbed areas, except the access route running surfaces, will be reseeded with seed
mixes as specified by Tri-State.
BR-6 All construction materials and debris shall be removed from the project area.
BR-7 In order to preclude avian electrocutions and minimize collision risk, Tri-State will incorporate
Avian Protection Plan (APP) standards developed by the Avian Power Line Interaction

NW-1 To minimize introduction of noxious weed seed sources to the project area the following
measures will be performed : All heavy equipment utilized during construction will be washed
prior to departure from the equipment storage facility. Washing of equipment prior to transport
from one work site to another is not recommended , as on-site washing of equipment increases
the chance of weed seed dispersal by drainage of water off of the site, across an area greater
than the size of the work site. Equipment will have accumulations of mud `knocked off' instead.
This method promotes containment of weed seeds on the work site; all seed mixes and mulch
used for reclamation activities will be certified weed-free.
Soils and Geology
S- 1 The contractor shall mitigate soils compacted by movement of construction vehicles and
equipment, by 1 . ) loosened and leveled harrowing or disking to approximate pre-construction
contours and 2. ) reseeded with certified weed-free grasses and mulched (except in cultivated
fields). The specific seed mix(s) and rate(s) of application will be determined by Tri-State .
S-2 Movement of construction vehicles and equipment shall be limited to the right-of-way and
approved access routes.
S-3 Excavated material not used in the backfilling of poles shall be spread around each pole,
evenly spread on the access routes in the immediate vicinity of the pole structure or
transported off-site to a Tri-State approved disposal location . Disturbed areas shall then be
regraded to approximate pre-construction contours and reseeded as specified in S-1 .*
S-4 Topsoil will be removed, stockpiled, and re-spread at temporarily disturbed areas not needed
for maintenance access.*
Traffic
T-1 The contractor shall make all necessary provisions for conformance with federal , state and
local traffic safety standards and shall conduct construction operations so as to offer the least
possible obstruction and inconvenience to public traffic.
Water Quality and Erosion
WQ-1 Construction activities shall be performed by methods that prevent entrance or accidental
spillage of solid matter, contaminants debris, and other objectionable pollutants and wastes
into flowing streams or dry water courses, lakes and underground water sources. Such
pollutants and wastes include, but are not restricted to, refuse, garbage, cement, concrete,
sanitary waste, industrial waste, radioactive substances, oil and other petroleum products,
aggregate processing tailings, mineral salts and thermal pollution .
WQ-2 Dewatering work for structure foundations or earthwork operations adjacent to, or encroaching
on , streams or water courses shall not be performed without prior approval by Tri-State and
appropriate state agencies. Water and eroded materials will be prevented from entering the
streams or watercourses by constructing intercepting ditches, bypass channels, barriers,
settling ponds or other approved methods.
WQ-3 Borrow pits shall be so excavated that water will not collect and stand therein . Before being
abandoned , the sides of borrow pits shall be brought to stable slopes, with slope intersections
shaped to carry the natural contour of adjacent, undisturbed terrain into the pit or borrow area,
giving a natural appearance. Waste piles shall be shaped to provide a natural appearance.
WQ-4 Excavated material or other construction materials shall not be stockpiled or deposited near or
on stream banks, lake shorelines or other water course perimeters where they can be washed
away by high water or storm runoff or can in any way encroach upon the actual water source
itself.
WQ-5 Waste waters from construction operations shall not enter streams, water courses or other
surface waters without use of such turbidity control methods as settling ponds, gravel-filter
entrapment dikes, approved flocculating processes that are not harmful to fish , recirculation
systems for washing of aggregates or other approved methods. Any such waste waters
discharged into surface waters shall be essentially free of settleable material. Settleable
material is defined as that material that will settle from the water by gravity during a 1 -hour
quiescent period.
WQ-6 A Storm Water Management Plan shall be developed if required, to address all construction ,
reconstruction activities. The plan shall conform will all EPA and Best Management Practices
(BMP) requirements.
