DEPARTMENT OF THE INTERIOR
Bureau of Reclamation
Contra Costa Water District Multi-Purpose Pipeline Project,
Contra Costa County, California
AGENCY: Bureau of Reclamation, Interior.
ACTION: Notice of Intent to prepare a draft environmental impact
statement and notice of scoping meeting.
-----------------------------------------------------------------------
SUMMARY: Pursuant to Section 102(2)(c) of the National Environmental
Policy Act (NEPA), the Bureau of Reclamation (Reclamation) proposes to
prepare a draft environmental impact statement (DEIS) for Contra Costa
Water District's (CCWD) Multi-Purpose Pipeline (MPP) Project.
[[Page 46372]]
The Proposed Action is the construction and operation of two water
pipelines and supporting pumping facilities. These facilities are
required to supplement the Contra Costa Canal and provide adequate
water transmission capacity to meet the projected demand through the
year 2020.
The purpose of the meeting is to receive comments regarding the
appropriate scope of the DEIS. CCWD staff will make a brief
presentation to describe the proposed project, its purpose and need,
alternative pipeline alignments, and scenarios for construction and
operation. The public may comment on the environmental issues to be
addressed in the DEIS. If necessary due to large attendance, comments
will be limited to 5 minutes per speaker. Written comments will also be
accepted by the District through September.
DATES: A scoping meeting is scheduled for the project on Saturday,
September 18, 1997, at 7:00 p.m.
ADDRESSES: The scoping meeting will be held at the Bay Point Ambrose
Community Center, 3105 Willow Pass Road, Bay Point, California.
Information on the scoping meeting and the DEIS may be obtained from
Mr. Steve Edmondson, Bureau of Reclamation, South-Central California
Area Office, 2666 North Grove Industrial Drive, Suite 106, Fresno, CA
93727.
FOR FURTHER INFORMATION CONTACT: Mr. Steve Edmondson, Bureau of
Reclamation, (209) 487-5049; or Ms. Christina Ko Hartinger, Contra
Costa Water District, (510) 688-8335.
SUPPLEMENTARY INFORMATION: CCWD's MPP Project involves the following
improvements:
1. Multi-Purpose Pipeline. The multi-purpose pipeline is a capacity
improvement project for meeting year 2020 system demands of CCWD's raw
water system. The MPP would supplement the capacity of the Contra Costa
Canal (which carries raw water) with a treated water pipeline extending
approximately 22 miles from CCWD's Randall-Bold Water Treatment Plant
in Oakley, east to CCWD's Treated Water Service Area in Concord. The
MPP would terminate near CCWD's Bollman Water Treatment Plant near
Concord. This new treated water pipeline paralleling the canal would
free up canal capacity for raw water transmission. Under normal
operations, the MPP would convey treated water westward to CCWD's
Treated Water Service Area. In an emergency, the MPP could also carry
treated water eastward from CCWD's Bollman Water Treatment Plant. The
25-million-gallons-per-day (mgd) pipeline would be 36 inches in
diameter and approximately 22 miles long. CCWD is evaluating several
pipeline route alternatives including: the canal right-of-way, local
streets, and an active railroad corridor.
2. Raw Water Pipeline. The MPP Project also includes approximately
4 miles of 36-inch raw water pipeline (36 mgd) bypassing canal reach 4
from downstream of the Neroly Blending Facility to the canal near
Antioch. The raw water pipeline could be installed parallel and
adjacent to the MPP pipeline. The raw water pipeline is sized to meet
the year 2020 canal demands through the existing tunnel segment within
canal reach 4.
3. Treated Water Pump Station. The MPP Project includes a proposed
25-mgd pump station at the Randall-Bold Water Treatment Plant to pump
treated water from the plant through the multi-purpose pipeline. No
treatment plant capacity improvements are required for the MPP.
4. Raw Water Pump Station. The MPP Project includes a 36-mgd raw
water pump station that would be located downstream of the Neroly
Blending Facility and upstream of the tunnel. The pump station would
pump raw water from the Canal through the raw water pipeline.
5. Canal Gate Improvements and Neroly Blending Facility
Improvements. The MPP Project includes modifications to six of the
seven active check structures along the canal between pumping plant No.
4 and Mallard Reservoir at Bollman Water Treatment Plant. At each check
structure, CCWD would install motorized gates that could be opened
during periods of high flow rates, thereby increasing canal capacity.
The Neroly Blending Facility (an in-canal facility to blend Delta water
and water from the Los Vaqueros Reservoir) would be expanded by
widening the canal or raising the sides.
6. Back-up Power for MPP Treated Water Pump Station. As part of the
MPP Project, the District would install an emergency generator for the
firm capacity (four 1,000-horsepower pumps) at the MPP treated water
pump station.
7. MPP Enhancements. The District would construct emergency
connections from the MPP to the canal and to the shortcut pipeline,
thereby allowing the MPP to deliver water to functional portions of the
canal that may be disconnected from eastern supply sources during an
emergency such as an earthquake. In addition, these connections could
be used to temporarily supply treated water to the canal while portions
of the canal are out of service for maintenance.
These actions will be evaluated in accordance with the legislative
requirements of NEPA and other relevant regulations. CCWD is preparing
an environmental impact report (EIR) on the project, pursuant to the
California Environmental Quality Act (CEQA).
