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 proposed to prepare an Environmental
Assessment (EA) for the proposed Trinity Public Utility District (PUD)
Direct Interconnection Project on February 25, 2005. The USFS expressed
concerns regarding potential impacts to the northern spotted owl and
designated critical habitat and on Late Successional Reserve forest
areas. Based on a review of the USFS concerns, Western determined to
prepare an EIS, with USFS and BLM as cooperating agencies.
The EIS will address the environmental impacts of the removal of
about 5.3 miles of existing 12-kV distribution line and the
construction and operation of about 16 miles of new 60-kV transmission
line, a tap structure and associated equipment, and a new switchyard in
Trinity County. 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 (10 CFR part 1022).
Purpose and Need
Western proposes to establish a direct connection between Western's
Central Valley Project (CVP) and Trinity PUD at a higher voltage to
strengthen power deliveries and enhance reliability of service.
Delivery of CVP power to Trinity County, in part, is authorized by the
Trinity River Division Act.
Proposed Project Description
The proposed project would include (1) removal of about 5.3 miles
of old 12-kV distribution line from Trinity Power
[[Page 35267]]
Plant at Trinity Dam to a tap point about 0.75 mile west of Lewiston
Dam and construction of a new 60-kV transmission line to replace the
12-kV line on an expansion of the existing right-of-way (ROW), (2)
construction of a tap structure with three-way switch equipment on the
new 60-kV transmission line at the location near Lewiston Dam and a
radial 1.2 miles tap line south to the existing Lewiston Substation on
Trinity Dam Road, parallel to an existing distribution line, and (3)
construction of a new 60-kV transmission line on a new ROW from the tap
point west about 8.5 miles to the proposed new Weaverville Switchyard,
which would be located about two miles south of Weaverville on the east
side of Highway 299. Western will use the EIS scoping process to
explore and refine any reasonable alternatives to the proposed route.
The new single-circuit 60-kV line would be constructed on single
poles with steel reinforced aluminum conductors on horizontal line post
insulators. An overhead ground wire or a fiber optic cable for remote
operation of the transmission line would be mounted above the
conductors. The poles would be 50 to 100 feet high, and the span
between poles would average 350 feet. Specific spans could range from
100 to 500 feet. On average, there would be 17 poles per mile of
transmission line, with approximately 272 poles required for the entire
project. Pole heights, locations, and span lengths would vary depending
on terrain and topography; structural limitations; cost; visual
considerations; existing and proposed land uses; crossings of roads,
canals, and other overhead lines; and other features specific to the
project. Each pole would be set 8 to 10 feet deep in an augured hole,
backfilled with excavated material. Some locations would not be
accessible by vehicles on the ground; at these locations holes would be
hand-dug and the poles flown in and set by helicopter.
The proposed new transmission line would require an 80-foot wide
ROW. Generally the ROW would be acquired by Western as a utility
easement; the underlying land owner or land manager would retain their
existing ownership. Existing access roads and logging roads would be
used to the extent possible for construction access, with a total of
approximately two miles of new access roads required. These would
primarily be short spurs from existing access roads to structure
locations which would be restored after construction and not maintained
as permanent roads. ROW clearing for the transmission line and new
roads would require cutting trees. Western would enter into a timber
contract with the landowner or land management agency for commercial
timber produced from ROW clearing activities. Slash would be chipped
for soil stabilization or piled for later burning in accordance with
landowner or manager requirements.
Additional details on the individual segments follow:
Segment 1--Trinity Power Plant to Lewiston Tap
Segment 1 would consist of about 5.3 miles of new 60-kV
transmission line between Trinity Substation at Trinity Power Plant and
the tap point west of Lewiston Dam. Except for the last couple of spans
to the tap point, and dropping off the hill east of the fish hatchery,
the new line would be centered on an existing ROW presently occupied by
a Trinity PUD 12-kV distribution line. This existing line would be
removed and the ROW expanded to 80 feet in width to accommodate the
larger transmission line. The old poles are not chemically treated and
would be left along the edge of the ROW, reutilized by the landowner or
manager, or cut up and placed in the slash piles for burning according
to the preference of the landowner or manager. Hardware, conductors,
and insulators would be removed from the ROW and reutilized or recycled.
Segment 1 would require about 90 new poles, four pulling sites, and
0.5 mile of access road. This segment passes through steep and rugged
terrain, mostly within the Shasta-Trinity National Forest, with
portions inside the Shasta-Trinity National Recreation Area, both
administered by the USFS. About 1.0 mile is administered by the Bureau
of Reclamation, 0.5 mile is owned by Sierra Pacific Industries (SPI),
and 0.25 mile is private land.
Segment 2--Lewiston Tap to Lewiston Substation
Segment 2 would consist of constructing approximately 1.2 miles of
new 60-kV transmission line between Lewiston Tap and Lewiston
Substation within a new ROW parallel to an existing Trinity PUD
distribution line. This radial feed would begin at the Lewiston Tap
structure at the termination of Segment 1 and proceed south to Trinity
PUD's existing Lewiston Substation on Trinity Dam Road north of
Lewiston. The tap structure would be a steel pole with a three-way
switch to accommodate the incoming Segment 1 line from Trinity
Substation, the Segment 2 tap line to Lewiston Substation, and the
outgoing Segment 3 line to the new Weaverville Substation. Existing
access roads would be used, with only very short spurs from the
existing parallel distribution line access road to the new structure
locations as needed.
Segment 2 would require about 20 new poles, two pulling sites, and
0.3 mile of access road. This segment would cross a mix of National
Forest, SPI, BLM, and private land as it parallels the Trinity River on
the west bank.
Segment 3--Lewiston Tap to Weaverville Switchyard
Segment 3 would consist of about 8.5 miles of new 60-kV
transmission line in a new ROW starting at Lewiston Tap. The line route
would proceed west and northwest, then generally southwest to the site
of the proposed new Weaverville Switchyard, located about two miles
south of the center of Weaverville on the east side of Highway 299.
Most of the area that would be crossed is also steep and rugged terrain
similar to Segment 1. Existing access and logging roads would be used
to the extent possible, with new roads limited to spurs to reach individual
structure locations. Inaccessible areas would be reached by helicopter.
Segment 3 would require about 144 new poles, six pulling sites, and
1.2 miles of new access road. This segment would pass through land
mostly owned by SPI, with much of the remaining property managed by
BLM. About 0.25 mile is privately owned. Although this area is also
rugged terrain, the route follows an existing SPI main access road
along a ridge for much of its length avoiding the steeper areas and
minimizing the need for new access roads.
Weaverville Switchyard
The proposed new Weaverville Switchyard would be constructed about
two miles south of the center of Weaverville on the east side of
Highway 299. This facility would have a footprint of approximately 90
by 110 feet, which would be located next to an abandoned section of old
Highway 299. The old highway section would be used for access to the
new switchyard. Two spur lines would connect the switchyard with a 60-
kV transmission line nearby, presently owned by the Pacific Gas and
Electric Company. This 60-kV transmission line would be acquired by the
Trinity PUD. The spur lines would replace one span of the existing
line, thus looping the line in and out of the proposed new switchyard.
The site is forested and would be obtained from BLM. Any commercial
timber resulting from clearing the site would be
[[Page 35268]]
purchased from BLM under one of the timber contracts.
Alternatives
An alternative alignment of the tap line from Lewiston Tap to
Lewiston Substation was identified, and an alignment crossing above
Lewiston Dam was also explored. Western will use input from the public
scoping process to determine if other alternatives should be developed
and analyzed.
No Action Alternative
Under the No Action alternative, none of the proposed facilities
would be constructed, and the existing 12-kV distribution line would be
left in place.
Agency Responsibilities
Western has determined an EIS is required, in light of concerns
about potential impact on northern spotted owls, their designated
critical habitat, and on Late Successional Reserve forest. Western will
be the lead Federal agency for preparing the EIS, as defined in 40 CFR
1501.5. In addition, USFS and BLM have been designated cooperating
agencies. Western invites interested agencies, tribes, organizations,
and members of the public to submit comments or suggestions to assist
in identifying environmental issues and in determining the proper scope
of the EIS. Western will invite other Federal, State, and local
agencies, and tribal governments 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
This notice is to inform agencies and the public of the proposed
project and solicit comments and suggestions for consideration in
preparing the scope of 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 ground water 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 scope of 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 open-house public scoping meetings;
consultation and involvement with appropriate Federal, State, and local
agencies, and tribal governments; public review and hearings on the
published Draft EIS; a review and comment period; a published Final
EIS; and publication of a ROD. The USFS and BLM will publish separate
RODs on their agency decisions. Additional informal public meetings
could be held in the proposed project area if public interest and
issues indicate a need. 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.
Western will hold a 30-day scoping period to ensure interested
members of the public, representatives of groups, and Federal, state,
and local agencies, and tribal governments have an opportunity to
provide input on the scope of alternatives and issues that will be
addressed in the EIS. As part of the scoping period, Western will hold
public open-house scoping meetings near the project area. Interested
individuals and groups are invited to attend anytime between 3 p.m. and
7 p.m. according to the dates and locations noted above. The open-house
scoping meetings 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 by fax, e-mail, U.S. Postal
Service, or other carrier to the Western contact provided under
Addresses above. To be assured consideration, all comments or
suggestions regarding the appropriate scope of the document must be
received by July 19, 2006.
Comments on the proposed project may, however, be submitted at any
time during the consultation and comment period of the EIS process.
Dated: June 13, 2006.
