DEPARTMENT OF THE INTERIOR
Bureau of Reclamation

San Luis Low Point Improvement Project, California

AGENCY: Bureau of Reclamation, Interior.
ACTION: Notice of intent (NOI) to prepare an environmental impact
statement/environmental impact report (EIS/EIR) and notice of public
scoping meetings.

-----------------------------------------------------------------------

SUMMARY: Pursuant to the National Environmental Policy Act and the
California Environmental Quality Act, the Bureau of Reclamation
(Reclamation) and the Santa Clara Valley Water District, in
coordination with the San Luis and Delta Mendota

[[Page 50998]]

Water Authority, intend to prepare an EIS/EIR for the San Luis Low
Point Improvement Project (Low Point Project). Reclamation is the lead
Federal agency and Santa Clara Valley Water District is the lead State
agency for preparation of the EIS/EIR.
    The Low Point Project is designed to address water supply
reliability issues in San Luis Reservoir associated with conditions
occurring in summer months when water levels are low. During this time,
reservoir-wide growth of algae makes the water unsuitable for certain
agricultural and municipal and industrial users in the San Felipe
Division with existing treatment facilities (also known as the ``low
point issue'').

DATES: A series of public scoping meetings will be held to solicit
public input on alternatives, concerns, and issues to be addressed in
the EIS/EIR. The meeting dates are as follows:
    • September 10, 2008, 4:30 p.m. to 7:45 p.m., San Jose, CA.
    • September 11, 2008, 10 a.m. to 12 p.m., Sacramento, CA.
    • September 11, 2008, 5 p.m. to 9 p.m., Los Banos, CA.
    Written comments must be received by October 28, 2008.

ADDRESSES: The public scoping meeting locations are:
    • San Jose at the Rose Garden Public Library, 1580 Naglee Avenue.
    • Sacramento at the Federal Building, 2800 Cottage Way,
Cafeteria Conference Rooms C-1001 and C-1002.
    • Los Banos at the Miller and Lux Community Center, 830 Sixth Street.
    Written comments on the scope of the EIS/EIR should be sent to Ms.
Lynnette Wirth, Bureau of Reclamation, 2800 Cottage Way, Public
Affairs, Sacramento, CA 95825, e-mailed to lwirth@mp.usbr.gov, or faxed
to 916-978-5114.

Manager, at the above address, 916-978-5086 (TDD 916-978-5608), or via
e-mail at: smchale@mp.usbr.gov; or Ms. Tracy Ligon, Santa Clara Valley
Water District, 5750 Almaden Expressway, San Jose, CA 95118-3686, at

SUPPLEMENTARY INFORMATION: San Luis Reservoir is a jointly shared off-
stream storage facility providing Reclamation and the State of
California the ability to store water during wet seasons and deliver it
during dry seasons. Use of the reservoir helps to maximize Central
Valley Project (CVP) and State Water Project supplies and contract
deliveries. Any constraint in the release of water from San Luis
Reservoir, including maintaining water levels to avoid the low point
issue, could limit water supplies.
    The Low Point Project is designed to address water supply
reliability issues in San Luis Reservoir associated with the low point
issue. The low point issue arises when water levels fall below 300
thousand acre-feet (TAF), creating a water quality restriction (algae
blooms) that has the potential to interrupt a portion of the San Felipe
Division's water supply. The low point issue may affect the ability of
San Luis Reservoir to provide water supply reliability and deliveries
to south-of-Delta contractors.
    Conditions at San Luis Reservoir promote the growth of reservoir-
wide algae during the summer months, when the reservoir reaches the
lower water surface elevations (approximately 300 TAF). Algae blooms
vary in size in different years, but generally reach diversion
facilities when the reservoir has 300 TAF of water remaining in
storage. The water quality within the algal blooms is not suitable for
agricultural water users with drip irrigation systems in San Benito
County or for municipal and industrial water users relying on existing
water treatment facilities in Santa Clara County. Reaching 300 TAF
creates a risk for the San Felipe Division contractors because the San
Luis Reservoir is the only CVP water source point that they can access.
    The project location is focused around San Luis Reservoir in Merced
County. The project also includes the service areas of the CVP San
Felipe Division in Santa Clara and San Benito Counties, and other CVP
contractors within the San Luis and Delta Mendota Water Authority in
the western San Joaquin Valley.

Background

    One of the options identified in the 2000 CALFED Programmatic
Record of Decision was a bypass canal that would connect the San Felipe
Division to water delivered by the Sacramento-San Joaquin River Delta
pumping facilities, to increase use of water in San Luis Reservoir by
up to 200 TAF.
    Reclamation issued a Notice of Intent (NOI) for a similar project
on July 17, 2002. The participating agencies conducted scoping
meetings, and the results of those meetings have been incorporated into
this project. After publishing the initial NOI, the project focus has
broadened, which has resulted in new planning objectives. The agencies
have decided to re-issue the NOI and conduct new scoping meetings
because of the length of time that has passed and the change in project
objectives.

Objectives

    The overall objective of the Low Point Project is to optimize the
water supply benefit of San Luis Reservoir while reducing additional
risks to water users by:
    • Avoiding supply interruptions when water is needed by
increasing the certainty of meeting the requested delivery schedule
throughout the year to south-of-Delta contractors dependent on San Luis
Reservoir;
    • Increasing the reliability and quantity of yearly allocations
to south-of-Delta contractors dependent on San Luis Reservoir; and
    • Announcing higher allocations earlier in the season to
south-of-Delta contractors dependent on San Luis Reservoir without
sacrificing accuracy of the allocation forecasts.
    The Low Point Project may also provide opportunities for ecosystem
restoration.

Alternatives

    Initial alternatives fall into seven general categories:
    • Institutional: Non-structural measures, including
agreements and exchanges that would reduce the likelihood of San Luis
Reservoir reaching its functional low point or would provide alternate
supplies for the San Felipe Division during times when the functional
low point is reached.
    • Source Water Quality Control: Improvements to San Luis
Reservoir water quality that would reduce water supply interruptions
for the San Felipe Division while continuing supplies for the rest of
the San Luis and Delta-Mendota users.
    • Water Treatment: New or enhanced raw water treatment
capabilities using dissolved air flotation that could treat San Luis
Reservoir water and reduce or eliminate interrupted deliveries when
algae blooms are in the vicinity of the Pacheco Intake.
    • Conveyance: Facilities that would allow San Felipe
Division CVP supplies to bypass the San Luis Reservoir altogether or
change the location of the San Felipe Division's intake so that low
water levels and algae are not a problem.
    • Storage: Facilities that would create additional storage,
either on the San Felipe side of San Luis Reservoir or within the
Central Valley, to provide an alternate water supply.
    • Alternate Water Supplies: Measures that would provide a
new source of water to users in the San Felipe

[[Page 50999]]

Division, reducing their demands on San Luis Reservoir water supplies.
    • Combination Alternative: Measures that work best in
combination, augmenting efficient use of existing available water
supplies and facilities to resolve the low point problem. The
Alternative Water Supplies concept incorporates multiple strategies,
such as source shifting, new supply development, additional treatment
technology, reoperation, and operational agreements, which build upon
one another either incrementally or in total, to achieve water supply
reliability, water quality, and system flexibility project objectives
and opportunities.
