Article II, Division 4. It is the responsibility of the applicant to be knowledgeable of the specific requirements of the Weld
County Code, Chapter 23,Article II, Division 4,for the use by Special Review application process.
Uses by Special Review are uses which have been determined to be more intense or to have a potentially greater
Impact that the Uses Allowed by Right in a particular zone district. Therefore, Uses by Special Review require
additional consideration to ensure that they are established and operated in a manner that is compatible with existing
and planned land uses in the neighborhood. The additional consideration of Uses by Special Review is designed to
protect and promote the health, safety, convenience, and general welfare of the present and future residents of Weld
County.
The Department of Planning Services is responsible for reviewing and processing the application in accordance with
Section 23-2-210 of the Weld County Code. The Planning Commission will consider the application in accordance with
Section 23-2-220 of the Weld County Code. The Planning Commission will provide a recommendation to the Board of
County Commissioners concerning the application. The Board of County Commissioners will consider the application in
accordance with Section 23-2-230 of the Weld County Code.

present the proposal and answer any questions. The applicant is also encouraged to communicate with the Current
Planner assigned to process and review the application once it has been submitted in order to keep up to date with any
developments pertaining to the application.

Services.
APPLICATION REQUIREMENTS:

A form of vested property right will be established for a three year period upon the effective date of the Board of County
Commissioners' final or conditional approval of a Special Review permit. The vested right runs with the property and
gives the landowner the right to undertake and complete development of the Special Review permit. Weld County may
attach terms and conditions to the Special Review permits as may be reasonably necessary to protect the public health,
safety, and welfare. Failure by the landowner to abide by any of the terms and conditions will result in a forfeiture of the
vested property right. Approval of a vested property right shall not constitute an exemption from or waiver of any
provisions of Weld County's regulations pertaining to the development and use of property.
INVESTIGATION FEE
An additional fifty percent of the permit fee shall be added to the cost of the Special Review permit application fee when
the use is started without a Special Review permit. The payment of the investigation fee shall not relieve any persons

PROJECT DESCRIPTION (SATISFIES 21 -3-330.C.1 .A-G)
Introduction
This document is submitted in support of a request by Tri-State Generation and Transmission
Association, Inc. (Tri-State) and United Power Inc. (United Power) to review the proposed
Davis 115-kilovolt (kV) Substation and Transmission Line Project (Project) under the
provisions of the Weld County 1041 process. This submittal includes a description of the
proposed Project and presents the purpose and need for the Project, which is situated on
privately owned property in Weld County.
Project Description
Tri-State and United Power are proposing to construct a new 115-kV transmission line and
electrical substation (Davis substation) in Weld County. The proposed transmission line
would begin at Xcel Energy's (Xcel's) Hudson-Fort Lupton 115-kV transmission line, proceed
north (paralleling the existing Xcel Fort Lupton-Pawnee 230-kV transmission line on the west
side), and terminate at the proposed Davis substation located on the NEY4 of the NWIA of
Section 14, Township 2 North, Range 66 West. The transmission line alignment and
substation location is zoned agricultural.
An application for a Recorded Exemption (RE) has been submitted prior to completion of this
Use by Special Review(USR) 1041. This RE will create four lots in the northwest corner of
Section 14. The Davis substation will be located on Lot of this RE.Inited Power intends
to purchase this site after approval of the RE and this USR 1041.
The proposed Davis substation will be located just east and south of an existing oil and gas
production facility owned by Anadarko/Kerr McGee (Anadarko) (USR-1353AM,
SUP-211AM2, USR-1291, and USR-1002AM3). The proposed substation will be adjacent to
the proposed amine and cryogenic facility (Lancaster Plant USR 12-0023) to be operated by
Anadarko. The new amine and cryogenic facility will be associated with the existing
production facilities, but will not be a part of the existing USR cases west and north of the
proposed site.
Purpose and Need
The proposed Davis 115-kV Substation and Transmission Line Project is needed to provide
electricity to Anadarko's proposed amine and cryogenic facility (Lancaster Cryogenic Plant)
and expansion of their existing facilities on that site. That proposed facility and expansion will
require additional electricity that is not currently available with the existing distribution lines. In
addition, the Davis substation will increase service reliability in the surrounding area, and
provide capacity for future growth. The anticipated in-service date for the Project is
December 2012.
Alternatives to the Proposed Project
Electrical System Alternatives
Three electrical system alternatives were evaluated to address the need of the Project.
Alternative 1: No Action. Taking no action would result in no power delivery to Anadarko's
Lancaster Facility. The No Action Alternative does not meet the need of the Project.

Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
Alternative 2: Construct a 230-kV transmission line from Xcel's Fort Lupton-Pawnee 230-kV
transmission line and construct the Davis substation. Although the Fort Lupton-Pawnee
230-kV transmission line is closer to the proposed Davis substation location, a system impact
study is required to be performed by Xcel before this alternative can be validated. The system
impact study would have taken over a year to complete. Alternative 2 does not meet the need
of the Project to be in service by January 2013.
Alternative 3: Construct a transmission line connecting Xcel's Hudson-Fort Lupton 115-kV
transmission line to the proposed Davis substation. Alternative 3 would involve the
construction of approximately 1.5 miles of 115-kV transmission line.
Preferred System Alternative
The preferred system alternative is Alternative 3. Alternative 3 meets the Project's purpose
and need and provides a timely, cost-effective, secure, and reliable source of power for the
proposed Lancaster Cryogenic Plant.
Transmission Line Routing
An opportunities and constraints analysis was completed for the study area to help determine
potential routes for the transmission line (Figure 1).
Three (3) routes were determined to be feasible based on the analysis.
Route 1:
Route 1 is the preferred transmission line route. Route 1 would parallel Xcel's existing Fort
Lupton-Pawnee 230-kV transmission line on the west side for majority of the length. In the
middle of Section 14, the transmission line would turn west and then proceed north for
approximately 1/8 mile and terminate at the Davis substation.
Route 1 would make use of an existing transmission corridor. The new transmission line
could be placed west of the existing 230-kV line (overlapping Xcel's existing easement) and
would require only a small additional right-of-way from landowners. It is preferable to place
the new transmission line west of the 230-kV line, rather than on the east side (Route 2)
because it would have impact landowners less since it would be closer to the parcel
boundary and would not require additional right-of-way east of the existing 230-kV
transmission line.
Route 2:
Route 2 would parallel Xcel's 230-kV Fort Lupton-Pawnee transmission line on the east side.
The same landowners would be affected as those for Route 1, but Route 2 would occur
farther into the parcel, rather than on the boundary. Route 2 also would require crossing
under the existing 230-kV transmission line to get to the Davis substation.
Route 3:
Route 3 would be located the farthest east on the eastern boundary of Section 23 and 14. At
the half-section line of Section 14, Route 3 would turn west and follow the half-section line to
Anadarko's property, where it would turn north for 1/8 mile into the Davis substation. Route 3
would create transmission lines on each side of two parcels and would not follow any existing
linear infrastructure. It also is the longest alternative.

Construction of the transmission line would not create runoff in excess of
previous site levels and would not change existing topography or adversely affect
drainage. There would be no alteration in the pattern or intensity of surface
drainage as a result of construction or operation of the transmission line facility.
The proposed substation site is relatively flat and would be surfaced with gravel.
A drainage report would not be required for the site. The stormwater drainage
collected from this site would collect via natural contours in the land and travel to
a retention pond outside of this lot, immediately west on Anadarko's site. A
description of historic stormwater flows across the site is included in Appendix A.
See Sections 21-3-330.8.12—Air and Water Pollution Impacts and Control
Alternatives, Air Pollution Impact and Control, and 21-3-330.8.16-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.
Drainage of the Davis substation is included in the Lancaster Cryogenic Plant
USR Application as part of the design of the entire site.
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.
Right-of-way agreements include 100-foot easements purchased from landowners
along the transmission alignment. Only a small portion of the transmission line right-
of-way would be disturbed for structure installation and vehicle access. No new roads
would be needed to gain access to sites where the poles would be erected.
Additional parking and storage would occur immediately north of the proposed Davis
substation between the County Road and the substation yard within the parcel of
land to be purchased by United Power. See Section 21-3-330.8.2.b—Access to the
Project Area.
During construction, all vehicles would be parked within the designated parking area
adjacent to the Davis substation. See Section 21-3-330.8.7—Natural and
Socioeconomic Environmental Impacts from Construction of the Electric
Transmission Line.
7. The USE shall comply with all the SETBACK and OFFSET requirements of the zone
district.
This Project is located within the A (Agricultural) Zone District. The minimum setback
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. This Project complies with
the setback and offset requirements, as shown in Figure 2.

13
Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
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
the proposed transmission line and substation are consistent with the intent of the
Comprehensive Plan, including Land Use, Environmental Resources, and Natural
Resources.
Weld County Code, Chapter 22, states "The Comprehensive Plan is intended to be
used for the general purpose of guiding and accomplishing the coordinated, adjusted
and harmonious development of the County"(Sec.-22-1-100). It further states that
the "Comprehensive Plan is a long-range look into the future, a twenty-year vision of
changes"(Sec-1-10, B.). This proposal is consistent with surrounding industrial uses
to the west and the existing transmission line to the east. In addition, this Project
would provide a power source that could handle future growth development in the
area. This Project is consistent as described by the intent of the Weld County Code
Chapter 22 of the Comprehensive Plan under the Industrial Development section.
Under subparagraph A-D, this intent has been further delineated.
Subparagraph A. states "The intent of the industrial Goals is to establish industrial
areas where a balanced, diversified economy can be encouraged in an effort to
maintain and enhance the quality of life of Weld County citizens." This proposal
would fit in well with other industrial sites located along the same corridor.
Subparagraph B. states "When reviewing proposed industrial development, there
should be a thorough examination of issues, such as compatibility with surrounding
and regional land uses, availability and adequacy of infrastructure and services
serving the proposal and impacts on the natural environment."Again, the proposal is
compatible with surrounding land uses, and proposes to utilize the existing
transmission infrastructure to feed power into the electrical substation.
Subparagraph C. states "It is essential to have supporting utilities, public services
and related facilities for any industrial development. The fiscal limitations of both the
private and public sector cannot sustain indiscriminate development without regard
for how such services and facilities will be provided."United Power's proposal is
driven by Anadarko's growth; however, the surrounding area would benefit because
additional capacities would be in place for reliability purposes as well as growth
opportunities.
14
Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
Subparagraph D. states "Industrial development can occur throughout the County in
a variety of targeted locations, and it differs in intensity and character."The proposal
selected was a targeted area, which meets the needs of both Anadarko and United
Power. This targeted location is near Anadarko's facilities and an existing
transmission line.
Section 22-2-10(D) emphasizes the extraction of natural resources as an important
part of the economy of the County. Development of this site would contribute to the
expansion of the county's industrial economic base by providing increased capacity
to an essential function in the production of natural gas in the County.
The Comprehensive Plan also addresses the presence of oil and gas deposits in the
County and encourages the extraction of oil and gas resources that conserve the
land and minimize the impact on surrounding land and the existing surrounding land
uses. The proposed facility would address the increase of natural gas liquids from
newly developed wells in the area. These liquids must be separated for the delivery
of products to customers. The proposed substation would directly support the
extraction of oil and gas resources in Weld County.
See Section 21-3-330.8.7—Natural and Socioeconomic Environmental Impacts from
Construction of the Electric Transmission Line.
2. A statement which explains that the proposal is consistent with the intent of the
district in which the USE is located.
Chapter 23 of the Weld County Code describes its purpose as "...to promote the
health, safety, convenience, morals, order and welfare of the present and future
inhabitants of the COUNTY."This proposal is consistent with the intent of Chapter 23
of the Weld County Code because by allowing the proposal, the County would be
assisting in providing electricity for the following purposes:health, safety,
convenience, order and welfare of the County inhabitants, both current and future.
In addition, 23-1-40 8-8 of said chapter states, "Otherwise planning for and
regulating the USE of land so as to provide planned and orderly USE of land and
protection of the environment in a manner consistent with constitutional rights."
United Power worked diligently with Anadarko to mitigate the impact of surrounding
lands and environment when looking at property options for this proposal. United
Power recommended a site immediately adjacent to an existing transmission line and
near a county road for the distribution exits of the electrical substation.
The proposed use is consistent with the intent of the Weld County Code. Public
utilities facilities are allowed as a use by special review in the A (Agricultural) Zone
District according to Section 23-3-40(D) of the Weld County Code. This Project would
incorporate natural vegetation outside of the immediate electrical substation
component and along the transmission line right-of-way. This would allow the Project
to blend in to a natural environment of that specific area.
15
Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
See Section 21-3-330.8.5.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.
A variety of land uses surround the proposed Davis substation. To the west and north
there are two oil and gas production facilities operated by Anadarko. To the east and
south there are large tracks of agricultural land. The home nearest to the proposed
site is located 0.6 mile east on Weld County Road(WCR) 22. Consideration has
been taken to ensure that the Davis substation would operate in a manner
compatible with existing and planned uses in the area. This new substation would
support the proposed Lancaster Plant as well as future growth in the area.
The proposed transmission line alignment crosses rangeland and is immediately
adjacent to Xcel's Fort Lupton-Pawnee 230-kV transmission line. The proposed
transmission line would not impact any agricultural uses in this area. The closest
residence to the proposed transmission line is approximately 500 feet away.
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 21-3-330.8.5.a—Present Use and Zoning.
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.
Not applicable. The Project area is not within an Overlay District Area, as defined in
Article V.
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.
The proposed Davis substation is located next to a proposed cryogenic and amine
facility and an existing oil and gas production facility. The land for the Davis
substation is not currently in agricultural production.
The preferred transmission line alignment is located on the west side of Xcel's Fort
Lupton-Pawnee 230-kV transmission line between the fence line and the existing
transmission line. By siting the transmission line on the west side of the existing line,
16
Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
less agricultural land would be impacted. Currently, the area is rangeland with no
crops. See Section 21-3-330.8.15—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 and United Power electric facilities are designed, constructed, operated,

power to operate Anadarko's Lancaster Cryogenic Plant.
16. A description of the proposed fire protection measures.
As discussed in Section 21-3-330.8.5.g—Hazards and Emergency Procedures, 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 could cause or provide fuel for fires on
its easements and rights-of-way. There are no explosive substances associated with
the proposed transmission line. All Tri-State and United Power electric facilities are
designed, constructed, operated, and maintained to meet or exceed all applicable
standards of design and performance set forth in the NESC. The proposed line is
designed with overhead ground wires and grounded towers to keep the system from
becoming damaged by lightning.
All roads leading to and those in the proposed Davis substation area would be
designed and maintained to support fire apparatus. A turnaround may be constructed
as necessary to accommodate fire apparatus. United Power support personnel are
either in the field or on call at all times to provide technical assistance in fire
prevention and elimination.

21-3-330.B.5.b—d—Map Extent
Figure 7 illustrates all existing transmission lines of 115-kV or greater within 2 miles of the
Project site.
21-3-330.B.5.e—Type of Facility
The Project would involve constructing 2 miles of new 115-kV transmission line between
Xcel's Hudson-Fort Lupton 115-kV transmission line and the proposed Davis substation.
United Power would construct and maintain the Davis substation. Tri-State would own and
construct the new 115-kV transmission line. The transmission line would be a single-circuit,
115-kV line constructed on single-pole steel or wood structures within a 100-foot right-of-way.
The transmission line would consist of approximately 22-25 structures with three conductors.
The new 115-kV transmission line would provide the required electricity to power Anadarko's
Lancaster Cryogenic Plant, located adjacent to the proposed Davis substation.
21-3-330.B.5.f—Projected Development Schedule
A Project schedule is presented in Table 1.
Table 1 Project Schedule
Milestone Date
Easement Acquisition May-July 2012
Weld County Permit Granted August-September 2012
Materials Ordered Spring-Summer 2012
Construction Begins on Substation October 2012
Construction Begins on Transmission Line December 2012
Project in Service February 2013
21-3-330.B.5.g—Hazards and Emergency Procedures
The purpose of the proposed transmission line and substation facilities is to conduct
electricity. The greatest danger from a transmission line is direct contact with electrical
conductors. Accordingly, extreme caution must be exercised when operating vehicles and
equipment near the Project. 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 may cause or
provide fuel for fires on its easements and rights-of-way. There are no explosive substances
associated with the proposed transmission line. All Tri-State and United Power 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 line and substation would be unmanned and
controlled remotely. 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. The proposed transmission line and substation are designed with
overhead ground wires and grounded towers to protect the system from becoming damaged
by lightning.

Health and safety concerns associated with the Project, therefore, would be limited largely to
EMF from the transmission line. Electric fields are caused by voltage on an object (e.g.,
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.
The concept of prudent avoidance was considered in the siting and proposed construction
and operation of this facility; therefore, the transmission line corridor would be in a sparsely
developed area.
For the purpose of this study, EMF was modeled as a function of predicted magnetic field
levels, based on maximum load, from the proposed transmission line. Figure 8 shows
expected levels of EMF for the proposed 115-kV single-circuit transmission line. The graph
indicates that under typical operating loads, magnetic fields beneath the transmission line
would be approximately 14.76 milligauss (mG) and approximately 2.71 mG at the left edge of
the right-of-way and 3.51 mG at the right edge of the right-of-way. These levels are similar to
magnetic fields generated by common household appliances, power tools, and office
equipment (Table 2).

The Colorado Public Utilities Commission requires public utilities to weigh potential health
effects and the cost of mitigating those effects by using alignments that—limit exposures [of
electric and magnetic fields] to areas of concentrated population and group facilities such as
schools and hospitals-I (4CCR 723-3-180)(2)) —or by burying transmission lines.1 This Project
maintains suitable distances from such areas.
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 and United Power remain 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 E.
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.
46
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.

21-3-330.B.5.k—Total Acreage of the Parcel, Right-of-Way or Corridor under
Consideration
The surface area for the newly constructed transmission line and right-of-way on private land
would total approximately 12 acres. The new substation would be approximately 2.89 acres
in size.
21-3-330.B.5.l—Existing Land Use
The proposed Davis substation would be located on private land owned by Anadarko. The
land is zoned for agriculture and has oil and gas development.
The proposed transmission line is currently on rangeland and immediately west of Xcel's Fort
Lupton-Pawnee 230-kV transmission line.
21-3-330.B.5.m—Existing Land Uses of All Properties Adjacent to Parcel
A variety of land uses surround the proposed Davis substation. To the west and north there
are two oil and gas production facilities operated by Anadarko. To the east and south there
are large tracks of agricultural land. The home nearest to the proposed site is located 0.6 mile
east on WCR 22.
The proposed transmission line would be located on the west side of Xcel's Fort Lupton-
Pawnee 230-kV transmission line between the fence line and the existing transmission line.

21-3-330.B.5.n—Present Zone and Overlay Zones
The current zoning in the Project area is agricultural. The Project site is not situated within the
boundaries of a 100-year or 500-year floodplain (Federal Emergency Management Agency
1997). There are no Code of Federal Regulations (CFR) Part 77 restrictions (objects affecting
navigable airspace)within the Project area. The Project would not affect navigable airspace.

21-3-330.6.6—Natural and Socioeconomic Environmental Constraints
Affecting Site Selection and Construction
An opportunities and constraints analysis was performed for the new transmission line within
the Project study area. The opportunities and constraints criteria are provided in Table 3. The
substation location was determined by Anadarko in their overall site plan for the Lancaster
Cryogenic Plant.

The opportunities and constraints analysis yielded three possible alternatives for the
transmission line. The three alternatives were then compared based on the following:
• Number of residences within 100 and 500 feet
• Number of oil and gas wells within 150 feet
• Number of parcels crossed
• Number of communication towers within 100 feet
• Length of transmission line
• Length paralleling existing linear features
• Length of transmission line adjacent to county roads
• Length crossing historic sites
Several categories (e.g., habitat for threatened and endangered species, wetlands, surface
waters, raptor nests)were not found within the Project area and were, therefore, not included
in the comparative analysis. There also are no socioeconomic constraints associated with the
Project.
Based on the comparative analysis and landowner input (discussed in the Transmission Line
Routing section), the preferred route along the west side of Xcel's Fort Lupton-Pawnee
230-kV transmission line was selected. The preferred route minimizes impacts to natural
resources and current land use and maximizes use of an existing transmission line corridor.
50
21-3-330.8.7—Natural and Socioeconomic Environmental Impacts from
Construction of the Electric Facilities (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 rangeland and oil and gas development.
The Weld County Code, Chapter 22, Comprehensive Plan, has been reviewed and the
proposed transmission line is consistent with the intent of the Comprehensive Plan, including
land use, environmental resources, and natural resources.
The proposed transmission line would be located in an area that is zoned agricultural.
Although a transmission line is 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.
Ground disturbance generally would be limited to an area of approximately 625 square feet
around each pole. Construction of the proposed transmission line is not a catalyst that would
cause additional non-agricultural land uses on adjacent land. The long-term presence of
Xcel's Fort Lupton-Pawnee 230-kV transmission line and continued agricultural uses in the
same area provide an example of the complementary nature of the two uses.
The substation would be located adjacent to the Lancaster Cryogenic Plant, consolidating the
two uses onto Anadarko's property.
Transportation Impacts (satisfies 21-3-330.C.2.g)
In 2009, the average daily traffic count on WCR 22 in the area of the proposed Davis
substation was approximately 1,000 cars. Addition of the substation would have little effect on
that number, only adding sporadic trips from non-permanent employee vehicles. The
proposed plant would not adversely affect the area traffic from the current traffic that
accesses the neighboring sites. Documentation of an improvements agreement and road
maintenance agreement would be provided after such agreement is prepared.
Based on the existing utilization of WCR 22 and the lack of additional daily trips that the
proposed activities would generate, it does not appear that approving the proposed use
would be detrimental to the safety or welfare of the motoring public in Weld County.
Approximately 25 construction workers would be employed during the course of the
approximately 3-month construction period. Table 4 and Table 5 list the personnel and
equipment for each phase of construction for both the substation and transmission line. Table
6 lists the weight of construction vehicles.

Socioeconomic Impacts (satisfies 21-3-330.C.2.g and 21-3-330.C.3.a)
The community nearest the Project area is the town of Fort Lupton located approximately
1.5 miles to the southwest. It is anticipated that the Project would have a small beneficial
impact to the local economy. Construction contractors, regardless of origin, would likely
spend money in the town of Fort Lupton 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 would not interfere with safe and reliable
operation of the transmission line.
The Project area is located within the jurisdiction of the Fort Lupton Fire Protection District.
Public roads are maintained by the Weld County Department of Public Works. The nearest
hospital is the Longmont United Hospital, located Longmont, CO. 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
not cause any residents or businesses to be displaced. 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 site vicinity is characterized by agricultural uses, primarily farming and ranching.
The surrounding vegetation communities can be characterized as disturbed grassland.
Permanent removal of vegetation would occur at structure sites and within the substation
footprint. Construction of the proposed Davis substation would occur in an area that has been
previously disturbed, and impacts to native vegetation communities are expected to be
minimal. Access to transmission structures would be overland in nature and minimal
vegetation would be disturbed in access routes.
There are no surface waters or wetlands within the preferred transmission line alignment or
within the footprint of the Davis substation. Figure 9 presents a map of water resources within
two miles of the Project site.
The Project would not impact hydrologic flow of surface water or groundwater, nor would it
affect groundwater recharge.
Wildlife and Critical Wildlife Habitat
Given the established use of the site and the surrounding agricultural use, the area is unlikely
to support quality habitat for many species. Common wildlife such as coyote, fox, skunk,
rabbits, and various birds are likely to be present in the area and are expected to occasionally
pass through the site, but the site is not likely to support nesting or denning habitat for most
species. Only minimal impacts to wildlife are expected to occur, and these would likely be
limited to temporary disturbance from construction activities.
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) (APLIC 2006) and the APP guidelines (APLIC and U.S. Fish and Wildlife
Service [USFWS] 2005) to protect birds on power lines, as well as NESC-specified electric
conductor clearances.

The USFWS list of federally threatened or endangered species includes six wildlife species
and two plant species in Weld County: Mexican Spotted Owl, Least Tern, Piping Plover,
Whooping Crane, Black-footed Ferret, Preble's Meadow Jumping Mouse, Colorado butterfly
Plant, and Ute Ladies'-tresses.
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 Least Tern and Piping Plover are typically found near water. Least Terns are fish eaters
and prefer to nest on sandy or pebbly beaches around lakes and reservoirs, or on sandbars
consisting of sandy soils in river channels. Piping Plovers feed on a variety of beach-dwelling
invertebrates and nest on sandy lakeshore beaches, sandbars within riverbeds, or even
sandy wetland pastures. Given the lack of water and the intense agricultural land use, these
two species are not expected to occur in the Project area.
The Whooping Crane is a rare North American bird with the largest population migrating
between the Arkansas National Wildlife Refuge and the Wood Buffalo National Park. This
population uses the Central Flyway to migrate across Texas, Oklahoma, Kansas, Nebraska,
South Dakota, North Dakota, and eastern Montana. Whooping Cranes are listed by the
USFWS for Weld County as a potentially impacted species due the potential depletion of the
Platte River Basin. The USFWS considers projects with less than 0.1 acre-foot per year of
57
Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
depletion to be de minimis exceptions for water-related activities in the Platte River Basin.
The proposed Project may use water for dust abatement activities during construction;
however, water use will be below the de minimis threshold for depletion. No impacts to
Whooping Cranes are anticipated for this Project.
The Black-footed Ferret is the rarest mammal in North America; there are no surviving wild,
unmanaged populations. This animal is an obligate predator of prairie dogs and, as a general
rule, cannot survive in the absence of large prairie dog colonies. There are two populations of
Black-footed Ferrets in Colorado (both re-introduced): one west of Rangely near the Utah
border, and one southeast of Dinosaur National Monument (Colorado Parks and Wildlife
[CPW] 2011). Re-introduced ferrets in Wyoming are located in Shirley Basin, between
Medicine Bow and Casper (Wyoming Game and Fish Department 2011). Prairie dog colonies
were not observed in the vicinity of the Project site during surveys; therefore, the Black-footed
Ferret would not be impacted by the Project.
The Preble's Meadow Jumping Mouse is a federally threatened species in Colorado. 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 along the proposed route is highly unlikely. There is no suitable habitat or
designated critical habitat for the Preble's Meadow Jumping Mouse in or near the Project site,
therefore, no impacts to the species are expected.
The Ute Ladies'-tresses and Colorado Butterfly Plant are federally threatened plant species
associated with floodplains and wet meadows. The Project site does not support suitable
habitat, therefore, the Project would not impact these species.
In addition to federally listed species, state-listed species that could occur in or near the
Project area include the Western Burrowing Owl and Plains Sharp-tailed Grouse.
The Western Burrowing Owl is a state-threatened species that could occur in the Project
area. In northeastern Colorado, Burrowing Owls typically are associated with prairie dog
colonies. Burrowing owls can excavate their own burrows, but they usually depend on
burrows that have been started by burrowing colonial mammals, especially ground squirrels
and prairie dogs. Prairie dog colonies were not observed in the vicinity of the Project site;
therefore, the Western Burrowing Owl is not expected to be impacted by the Project.
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).
The Bald Eagle was removed from listing as threatened under the Endangered Species Act
on June 28, 2007, but has federal protection under the Bald and Golden Eagle Protection Act
and the Migratory Bird Treaty Act. The Bald Eagle is also a species of state special concern
in Colorado, although this designation is not a statutory category. Bald Eagles are found
throughout the continuous U.S. and Alaska, particularly in areas with large expanses of
aquatic habitat. Bald Eagles inhabit areas near reservoirs and rivers. In Colorado, mature
cottonwood groves found along streams and rivers are typically used as Bald Eagle nesting
and roosting habitat. Bald Eagles nest in Colorado from early February through the middle of
August. Wintering areas are commonly associated with open water or where other food
sources (e.g., rabbits, deer, carrion) are readily available. There are no known Bald Eagle
nesting or roosting sites near the Project area.
58
Unique Areas of Geologic, Historic, or Archaeological Importance
Tri-State performed a Class I archaeological database search of the Project area for sites
eligible or listed under the National Register of Historic Places (NRHP). There are no NRHP
eligible or listed sites within the Project area.
Vested Water Rights
The Project would not have impacts on vested water rights. Construction water and water to
suppress dust during construction activities would be trucked into the site.
21-3-330.6.8—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.
21-3-330.6.9—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
transmission 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. Environmental Protection Measures for Construction
Projects, included as Appendix B, addresses site reclamation of disturbed areas.
21-3-330.6.10—Non-Structural Alternatives
There are no non-structural alternatives that would accomplish the purpose and need for the
transmission line and overall Project. If the Project is not constructed, Tri-State and United
Power would be required to seek other locations to construct adequate facilities to
accomplish the Project goals.
21-3-330.6.11-Structural Alternatives
Two alternatives were considered in addition to the preferred alternative. These alternatives
are discussed in more detail in the Alternatives to the Proposed Project section.
21-3-330.6.12—Air and Water Pollution Impacts and Control Alternatives
Air Pollution Impact and Control (satisfies 21-3-330.C.2.d)
Construction would last approximately three months. Construction activities associated with
the proposed transmission line 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
excavating foundations and placing single-pole transmission structures. Air pollutants also
would be minimized through implementation of dust suppression and proper vehicle
maintenance. A water truck would be utilized to maintain dust suppression for during
59
Davis 115-kV Transmission Line and Substation
Weld County USR and 1041 Application
construction of the proposed Davis substation and transmission line, if needed. Therefore,
Project construction is not expected to contribute 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 line or substation. Once construction activities have been
completed, the site would be stabilized using native vegetation and access to the proposed
Davis substation would be paved.
Water Pollution Impacts and Control
There would be no direct impacts to water quality associated with regular operation or
maintenance of the transmission line or substation. The Project would not create runoff in
excess of historic levels and would not change existing topography or adversely affect
drainage. There would be no alteration in the pattern or intensity of surface drainage as a
result of construction or operation of the transmission line.
The substation would drain stormwater to Anadarko's detention pond as part of the overall
Lancaster Plant Site Plan.
21-3-330.6.13—Design Alternatives: Access, Landscaping, and
Architecture
Access to the proposed transmission line would be provided by existing roads and the
100-foot-wide right-of-way along the transmission line. No new roads would be required for
the transmission line construction. The access points would not require architectural or
landscape treatments beyond restoring any disturbed land to its preconstruction condition.
Access to the proposed Davis substation would be from WCR 22, utilizing an existing access
to the Project site.
21-3-330.6.14—New or Upgraded Services
New or upgraded services are not applicable to, and not required for, this Project.
21-3-330.6.15—Hydrologic, Atmospheric, Geologic, Pedologic, Biotic,
Visual, and Noise Impacts
Biotic and atmospheric impacts are described above.
Hydrologic
Construction and maintenance of the Project 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. The Project
would not impact hydrologic flow of either surface water or groundwater, nor would it affect
groundwater recharge.
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.
No water would be required for the operation of the transmission line or substation.
60
Geologic
Construction and operation of the electric transmission line would not alter the geology of the
Project area. The topography of the Project area is relatively flat; slopes range from 0 to
3 percent across the Project site.
Pedologic
Figure 10 shows the soil shrink/swell potential in the Project area. Shrink/swell potential of a
soil is based on the change in length of an unconfined clod as moisture content is increased
from air-dry to field capacity. The classes of shrink/swell potential are shown in Table 8. All of
the soils in the Project area have low shrink/swell potential.
Table 8 Soil Shrink/Swell Classes
Class Value
Low < 3%
Moderate 3-6%
High 6-9%
Very high > 9%
Figure 11 shows the soil erodibility based on factor K within the Project area. 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 0.05 to 0.69, with higher values indicating higher losses.
For the purpose of this report, soil K factors are classified based on Table 9.
Table 9 Soil Erodibility Classes
Class Factor K Value
Low 0.05-0.2
Moderate 0.21-0.4
High > 0.4
According to the Natural Resources Conservation Service (NRCS) Soil Survey of the
Northern Part of Weld County, the following general soil map unit complexes are found within
the Project area (NRCS 2012).
Vona Loamy Sand - The soils in this unit are deep, well drained, nearly level soils (0 to
9 percent and 3 to 9 percent)formed in alluvium and/or eolian deposits.
Erodibility:Vona soils have moderate erodibility.
Shrink/Swell Potential:Vona soils have low shrink/swell potential.
Olney Loamy Sand - The soils in this unit are deep, excessively drained, nearly level soil (1 to
3 percent)formed in mixed deposit outwash.
Erodibility: Olney soils have moderate erodibility.
Shrink/Swell Potential: Olney soils have low shrink/swell potential.

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.
Visual
The Project is not expected to significantly affect the aesthetics of the area. The northern part
of the Project crosses an abandoned turkey farm, which will become a dairy. Tank batteries
and a Federal Communication Commission tower occur within 0.5 mile of the southern
portion of the proposed transmission line. Given the span length and use of single-pole
construction, visual aesthetics of the area would be minimally impacted.
21-3-330.6.16-Surface and Subsurface Drainage
Subsurface drainage would not be impacted by the proposed transmission line. There would
be no direct impacts to water quality associated with regular operation or maintenance of the
transmission line or substation. Project construction would not create runoff in excess of
previous site levels and would not change existing topography or adversely affect drainage.
There would be no alteration in the pattern or intensity of surface drainage as a result of
construction or operation of the substation or transmission line facility. A range of measures
ensuring the Project does not impact water quality are listed in Appendix B; prior to
construction, a Storm Water Permit for Construction Activities would be acquired from the
Colorado Department of Public Health and Environment, if needed.

Historic Stormwater Flows for the Proposed Davis Substation
Site
CIVIL NARRATIVE
STORM WATER FLOWS
For The
UNITEDPOWER SUBSTATION SITE
General Location and Description:
The proposed United Power Substation is located south of County Road 22, between County Roads 31 and 37,in
the NE 1/4 of the NW 1/4, Section 14, Township 2N, Range 66W, 6th Principal Meridian, Weld County, Colorado.
The site will be accessible from County Road 22 by a gravel surfaced access road. The site is approximately 350-
ft x 400-ft or 3.2 acres. The vegetation on the site consists mostly of native prairie grasses. There are no perennial
or intermittent streams; there are also no water bodies within or immediately adjacent to the project site.
Historical Storm Water Flows:
Historically, off-site runoff enters the site from east northeast direction and flows across the proposed site
southwest and then in a west direction across the subject property. After leaving the proposed site the historic
flows trend northwest where it flows into an existing road side ditch along the south side of County Road 22. The
subject property has not shown to have a history of any surface drainage issues such as ponding or flooding.
Flow patterns for predevelopment drainage are shown on the attached drawing. (11-01-CE-0600)
Planning Goals:
The storm water planning goals include:
• Intercept all offsite flows and direct these flows to the existing roadside ditch along the south side of
County Road 22.
• Capture all onsite flows and direct these flows to a proposed localized Extended Detention Basin
(EDB). (Shown on attached drawing)
Developed Storm Water Flows:
Upon completion of the construction of the substation, the finished surface of the site will be a mixture of
recycled concrete and gravel. All off-site flows will be directed away from the site and into the existing County
Road 22 roadside ditch. To control on-site flows, the site will be graded to provide a cross slope of 1.25%
generally in a northwest direction. All on-site flows will be directed into the EDB before returning to the natural
flow pattern. An outlet structure at the low end of the EDB will be installed near the natural discharge point and
the flows ultimately enter the existing roadside ditch along the south side of County Road 22.
Off-site flows will be directed around the proposed site and continue to be captured into the existing
ditch along the south side of County Road 22 as historically outlined. Post development on-site storm
water flows will be discharged from the EDB at historical rates.

Appendix B:
Environmental Protection Measures for Construction Projects
TOPIC STANDARD ENVIRONMENTAL PROTECTION MEASURES
- No.
General
The contractor shall comply with all federal, state, and local environmental laws,
G-1 orders, and regulations. Prior to construction, all supervisory construction personnel
will be instructed on the protection of cultural and ecological resources.
Prior to construction, Tri-State shall discuss with the contractor areas of
G-2 environmental sensitivity within the Project area and, in particular, those areas
where a monitor must be present during construction.
Access Routes
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
AR-1 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.
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
AR-2 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.
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
AR-3 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
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
A-1 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.
The contractor shall minimize scarring, defacing, damage, or destruction of the
A-2 natural landscape resulting from construction operations. Any unnecessary or
unauthorized damage shall be repaired by the contractor to the satisfaction of Tri-
State.
All construction materials, waste, and debris shall be removed from the project area
A-3 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.
Structures will be located and designed to conform with the terrain and with minimal
A-4 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
The contractor shall utilize practicable methods and devices as are reasonably
AQ-1 available to control, prevent, and otherwise minimize atmospheric emissions or
discharges of air contaminants.
TOPIC STANDARD ENVIRONMENTAL PROTECTION MEASURES
- No.
AO-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.
Vehicles and equipment showing excessive emission of exhaust gases due to poor
AQ-3 engine adjustments or other inefficient operating conditions shall not be operated
until corrective adjustments or repairs are made.
Post seeding mulch will be utilized during reclamation activities to help reduce wind
AQ-4 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
Vegetation shall be preserved and protected from damage by construction
BR-1 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.
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
BR-2 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.
The contractor shall not cross any wetland and riparian areas (of or relating to, or
BR-3 located on, the banks of a river or stream), except at designated locations
designated by Tri-State
On completion of the work, all work areas, except any permanent access
BR-4 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 or United Power.
BR-6 All construction materials and debris shall be removed from the project area.
To preclude avian electrocutions and minimize collision risk, Tri-State will
incorporate Avian Protection Plan (APP) standards developed by the Avian Power
BR-7 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
Prior to construction, all supervisory construction personnel will be instructed on
CR-1 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.
Should any previously unknown historic/prehistoric sites or artifacts be encountered
during construction, all land-altering activities at that location will be immediately
CR-2 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 response providers and methods of contact/communication.
TOPIC STANDARD ENVIRONMENTAL PROTECTION MEASURES
- No.
Hazardous Materials
Tri-State and United Power 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 CFR,
Part 702-799 and especially, provisions on polychlorinated biphenyls, 40 CFR
HM-1 761.1-761.193.). 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.
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
HM-2 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.
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
HM-3 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
All activities associated with the construction, operation, and maintenance of the
transmission line will take place within the authorized limits of the transmission
LU-1 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.
The contractor shall maintain all fences, brace panels, and gates during the
LU-2 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.
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
LU-3 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.
Structure foundation holes will not be left open overnight and will be covered.
LU-4 Covers will be secured in place and will be strong enough to prevent livestock,
wildlife, or the public from falling.
Noise
Construction vehicles and equipment shall be maintained in proper operating
N-1 condition and shall be equipped with manufacturers' standard noise-control
devices or better (e.g. mufflers, engine enclosures).
TOPIC STANDARD ENVIRONMENTAL PROTECTION MEASURES
- No.
Noxious Weeds
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
NW-1 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
The contractor shall mitigate soils compacted by movement of construction
vehicles and equipment by 1) loosened and leveled harrowing or disking to
S-1 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.
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
S-3 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
The contractor shall make all necessary provisions for conformance with federal,
T-1 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
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
WQ-1 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.
Dewatering work for structure foundations or earthwork operations adjacent to, or
encroaching on, streams or water courses shall not be performed without prior
WQ 2 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.
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
WQ-3 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.
Excavated material or other construction materials shall not be stockpiled or
WQ 4 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.
TOPIC STANDARD ENVIRONMENTAL PROTECTION MEASURES
- No.
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
WQ 5 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.
A Storm Water Management Plan shall be developed, if required, to address all
WQ-6 construction and reconstruction activities. The plan shall conform with all U.S.
Environmental Protection Agency and Best Management Practices requirements.
TOPIC STANDARD ENVIRONMENTAL PROTECTION MEASURES
- No.
General
The contractor shall comply with all federal, state, and local environmental laws,
G-1 orders, and regulations. Prior to construction, all supervisory construction personnel
will be instructed on the protection of cultural and ecological resources.
Prior to construction, Tri-State shall discuss with the contractor areas of
G-2 environmental sensitivity within the Project area and, in particular, those areas
where a monitor must be present during construction.
Access Routes
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
AR-1 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.
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
AR-2 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.
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)
AR-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
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
A-1 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.
The contractor shall minimize scarring, defacing, damage, or destruction of the
A-2 natural landscape resulting from construction operations. Any unnecessary or
unauthorized damage shall be repaired by the contractor to the satisfaction of Tri-
State.
All construction materials, waste, and debris shall be removed from the project area
A-3 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.
Structures will be located and designed to conform with the terrain and with minimal
A-4 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
The contractor shall utilize practicable methods and devices as are reasonably
AQ-1 available to control, prevent, and otherwise minimize atmospheric emissions or
discharges of air contaminants.

HEADQUARTERS: P . BOX 33695 DENVER, COLORADO 80233-0695 303-452-6111
POSITION STATEMENT
Electric and Magnetic Field (EMF) Health Effects
Lights, appliances, computers, power lines and any other devices that carry or use electricity produce
electric and magnetic fields (EMF). The Earth itself also creates natural EMF in varying amounts.
Therefore, we are all continuously exposed to EMF as a result of living in a society that so heavily relies on
the use of electricity as a source of energy.
In recent years, concerns have been raised that exposure to EMF might cause or contribute to adverse
health effects, including cancer. We at Tri-State Generation and Transmission Association are aware of
these concerns and we wish to express our position on EMF and our commitment to this matter.
Scientists agree that the answers to these concerns must come from well-conducted research studies.
During the last three decades several thousand studies aimed at a better understanding of this issue have
been conducted around the world. The consensus of scientists familiar with these studies is that no
significant risk to humans from long-term exposure to EMF has been established.
In addressing this issue, Congress in 1991 asked the National Academy of Sciences to review the
research literature on the effects from exposure to EMF and for the National Institute of Environmental
Health Sciences (NIEHS) to conduct a scientific research program to evaluate the health risk to humans of
EMF. The National Academy of Sciences formed the Committee to Review the Research Activities
Completed Under the Energy Policy Act of 1992. The Committee issued their report in 1999 titled
"Research on Power-Frequency Fields Completed Under the Energy Policy Act of 1992." In the report
they state " the committee recommends that no further special research program focused on possible
health effects of power-frequency magnetic fields be funded."
The NIEHS in May 1999 prepared their report to Congress on the results of their sponsored research and
other research conducted to date around the world. In a letter accompanying this report, the NIEHS
Director concluded, "the scientific evidence suggesting that ELF-EMF exposures pose any health risk is
weak". He goes on to say "virtually all of the laboratory evidence in animals and humans and most of the
mechanistic work done in cells fail to support a causal relationship between exposure to ELF-EMF at
environmental levels and changes in biological function or disease status." While these scientific reviews
were conducted some time ago and EMF research has continued since then, the overall conclusions of
these newer studies remain about the same as before.
Tri-State recognizes its responsibility to provide wholesale electric service at the lowest possible cost in a
manner that is safe, reliable and environmentally sound. This responsibility includes carefully designing
and locating our facilities in strict accordance with the National Electric Safety Code and all applicable
federal, state and local regulations. Despite the lack of clear evidence from reliable studies of any adverse
effect EMF may have on human health, we will continue to construct and operate our facilities in a manner
that minimizes, to the extent prudent and practical, the amount of EMF that is created.
Since there are still unanswered questions and opposing theories, Tri-State agrees that limited research
should continue in a credible and objective manner even though the federal government has ceased
funding all such research studies. Accordingly, we will continue to be a sponsor of the EMF research
program of the Electric Power Research Institute, of which we are a member. We will continue to closely
monitor the results of these and other scientific studies as they are completed. Our commitment is to keep
our member systems, our employees and our electric consumers informed of the results of this research
and promptly and knowledgeably respond to all inquiries with accurate and current information.
