SUPPLEMENTARY INFORMATION: Western is a power marketing agency of DOE
that markets Federal electric power to statutorily defined customers,
including project use, municipalities, irrigation districts, and Native
American tribes. Western initially determined that an Environmental
Assessment (EA) would be prepared for the proposed Granby Pumping
Plant-Windy Gap Transmission Line Rebuild Project on February 25, 2005.
Western held open-house scoping meetings on July 28, 2005, and November
15, 2006. The public expressed numerous concerns about the impacts of
the project. Based on a review of the public's concerns, Western
subsequently determined that an EIS would be prepared.
The EIS will address the environmental impacts of the proposal to
remove about 12 miles of existing 69-kV transmission line and the
construction and operation of about 12 miles of new 138-kV double-
circuit transmission line (which would be operated at 69/138-kV), and
adding a second power transformer. Alternatives, including the no
action alternative, will also be addressed in the EIS. Western's EIS
process will comply with NEPA (42 U.S.C. 4321-4347, as amended),
Council on Environmental Quality regulations for implementing NEPA (40
Code of Federal Regulations [CFR] parts 1500-1508) and DOE NEPA
implementing procedures (10 CFR part 1021). Because the proposed
project may involve action in floodplains, the EIS will include a
floodplain assessment and floodplain statement of findings following
DOE regulations for compliance with floodplain and wetlands
environmental review requirements (10 CFR part 1022).
Description
Western's Rocky Mountain Region proposes to rebuild and upgrade the
Granby Pumping Plant-Windy Gap 69-kV transmission line, between the
Windy Gap Substation and the Granby Pumping Plant, a distance of
approximately 11.7 miles. The transmission line, which was constructed
on wood-pole H-frame structures, is located in Grand County, Colorado,
near the towns of Granby and Grand Lake. Other participants in the
project include Tri-State Generation and Transmission, Inc. (Tri-State)
and the Northern Colorado Water Conservancy District (NCWCD).
Western's Granby Pumping Plant-Windy Gap 69-kV transmission line
has been in operation approximately 65 years. It supplies electrical
power to the Colorado-Big Thompson Project (C-BT) facilities and
electrical substations operated by Mountain Parks Electric, Inc.
(MPEI), a Tri-State member operating company.
The area transmission system has also been served by the Bureau of
Reclamation's (Reclamation) Adams Tunnel 69-kV cable for the past 50
years, and the cable is at the end of its planned service life. The
Adams Tunnel 69-kV cable provides Tri-State with a second power source
for MPEI loads. In 1992, Western and Reclamation studied costs,
engineering requirements and electrical system constraints for
replacing the Adams Tunnel cable in anticipation of its eventual
failure. In 1994, Western and Reclamation decided not to replace the
cable if it fails.
For electrical service reliability, Tri-State must maintain a
second source of power for MPEI loads. The result of systems studies by
both Western and Tri-State demonstrated electrical system reliability
improvements when a new 138-kV transmission line was added between the
Windy Gap and Granby substations.
The NCWCD expressed interest in extending the 138-kV transmission
line directly to C-BT Project facilities at Granby Pumping Plant to
allow better voltage support for motor starting at Granby Pumping
Plant.
The proposed project includes the following actions.
Remove 10.0 miles of 69-kV circuit: Windy Gap Substation-
Stillwater Tap.
Remove 1.7 miles of 69-kV circuit: Stillwater Tap to
Granby-Granby Pumping Plant Substation.
Remove three 69-kV line switches at Granby Tap.
Construct 10.0 miles of 138-kV double-circuit transmission
line with overhead fiber optic ground wire (operated at 69/138-kV):
Windy Gap Substation-Stillwater Tap.
Construct 1.7 miles of 138-kV double-circuit transmission
line with overhead fiber optic ground wire (operated at 69/138-kV):
Stillwater Tap-Granby Pumping Plant Substation.
Install 69-kV three-way line switches at new Willow Creek
Tap (replaces Granby Tap).
Install 69-kV three-way line switches at Stillwater Tap.
Construct a new 138/69-kV Granby Pumping Plant Substation,
consisting of two circuit breakers with 138-kV main and transfer busses
and a 138/69-kV power transformer.
Install a new 69-kV circuit breaker at the existing 69/
6.9-kV Granby Pumping Plant Substation.
Install a new 138-kV circuit breaker bay at the Windy Gap
Substation.
The right-of-way for the existing transmission line is generally
30-feet wide, which is inadequate for new transmission line
construction and maintenance. Some segments of the proposed rebuilt and
upgraded transmission line would be constructed on new rights-of-way on
alternative alignments. Remaining segments of the transmission line
would be constructed on existing rights-of-way that will be widened to
accommodate construction, operation, and maintenance.
The proposed substation site for the new 138/69-kV Granby Pumping
Plant Substation would be approximately 200 feet by 150 feet in area,
and located entirely on Reclamation property.
No Action Alternative
Under the No Action alternative, none of the proposed facilities
would be constructed, and the existing 69-kV transmission line would be
left in place. Different transmission projects could be proposed by
other entities to strengthen the electrical system in the project area.
Agency Responsibilities
Western has determined that an EIS is required under DOE NEPA
implementing procedures, 10 CFR 1021, in light of the public's concerns
about potential impacts of the project. Western will be the lead
Federal agency for preparing the EIS, as defined in 40 CFR 1501.5. In
addition, the USFS has been designated a cooperating agency. Western
invites interested agencies,
[[Page 45042]]
Tribes, organizations, and members of the public to submit comments or
suggestions to assist in identifying environmental issues and in
determining the appropriate scope of the EIS. Western will invite other
Federal, State, local, and tribal agencies with jurisdiction by law or
special expertise, with respect to environmental issues, to be
cooperating agencies on the EIS, as defined in 40 CFR 1501.6. Such
agencies also may make a request to Western to be a cooperating agency.
Designated cooperating agencies have certain responsibilities to
support the NEPA process, as specified in 40 CFR 1501.6(b).
Environmental Issues
The EIS will address impacts from the proposed project and a range
of reasonable alternatives that achieve that same purpose and need.
This notice is to inform agencies and the public of the proposed
project and solicit comments and suggestions for consideration in
preparing the EIS. To help the public frame its comments, this notice
contains a list of potential environmental issues Western has
tentatively identified for analysis. These issues include:
1. Impacts on protected, threatened, endangered, or sensitive
species of animals or plants or their critical habitats;
2. Impacts on other biological resources;
3. Impacts on land use, recreation, and transportation;
4. Impacts on floodplains and wetlands;
5. Impacts on cultural or historic resources and tribal values;
6. Impacts on human health and safety;
7. Impacts on air, soil, and water resources (including air
quality, surface water impacts, and groundwater impacts);
8. Visual impacts; and
9. Socioeconomic impacts and disproportionately high and adverse
impacts to minority and low-income populations.
This list is not intended to be all-inclusive or to imply any
predetermination of impacts. Western invites interested parties to
suggest specific issues within these general categories, or other
issues not included above, to be considered in the EIS.
Public Participation
Opportunities for public participation are planned for the entire
EIS process. Western anticipates the EIS process will take about 12
months and will include an open-house public scoping meeting;
consultation and involvement with appropriate Federal, State, local,
and tribal agencies; public review and hearing on the published Draft
EIS; a published Final EIS; and publication of a Record of Decision.
Western will mail newsletters to the mailing list developed for the
proposed project to communicate project status and developments. Anyone
may request to be placed on the mailing list.
The scoping period will provide opportunity for interested members
of the public, representatives of groups, and Federal, State, local,
and tribal agencies to give input on the scope of alternatives and
issues that will be addressed in the EIS. As part of the scoping
period, Western will hold a public open-house scoping meeting near the
project area. Interested individuals and groups are invited to attend
anytime between 4 and 7 p.m., according to the date and location noted
above. The open-house scoping meeting will be informal, with Western
representatives available for one-on-one discussions with attendees.
Attendees will have the opportunity to view maps of the proposed
transmission line route, learn about the NEPA process and the proposed
schedule, suggest changes and improvements to the proposed project, and
obtain additional information. Written comments regarding environmental
issues, alternatives, and other scoping issues may be turned in at the
scoping meetings or may be provided to Western by fax, e-mail, U.S.
Postal Service, or other carrier. Although comments on the proposed
project may be submitted at any time during the EIS process, to be
assured consideration in helping define the scope of the EIS, all
comments or suggestions regarding the appropriate scope must be
received by the end of the scoping period. Comments received by Western
at or as a result of the July 28, 2005, and November 15, 2006, open
houses will be used to help define the scope of the EIS.
Dated: July 30, 2007.
