San Diego County Water Authority; Notice of Preliminary Permit
Application Accepted for Filing and Soliciting Comments, Motions To
Intervene, and Competing Applications

April 7, 2010.
    On March 1, 2010, San Diego County Water Authority filed an
application for a preliminary permit, pursuant to section 4(f) of the
Federal Power Act, proposing to study the feasibility of the San
Vicente Pumped Storage Water Power Project No. 13747. The proposed
project would be located at the existing San Vicente dam and reservoir
on San Vicente Creek in San Diego County, California. The project would
consist of the existing San Vicente reservoir functioning as the lower
reservoir of the project and one of three alternatives as an upper
reservoir: the Iron Mountain Alternative, the Foster Canyon
Alternative, and the East Reservoir Alternative. Specific details about
each of these alternatives are described below. The sole purpose of a
preliminary permit, if issued, is to grant the permit holder priority
to file a license application during the permit term. A preliminary
permit does not authorize the permit holder to perform any land-
disturbing activities or otherwise enter upon lands or waters owned by
others without the owners' express permission.
    All three of the alternatives would use the San Vicente reservoir
as the lower reservoir of the pumped storage project. The San Vicente
reservoir portion of the project would consist of:
    (1) an existing dam, currently being raised to a dam height of 337
feet, and a length of 1,442 feet; and (2) an existing impoundment, that
upon completion of the dam raise will have a surface area of 1,600
acres, and storage capacity of 247,000 acre-feet with a normal maximum
water surface elevation of 767 feet above mean sea level (msl).
    The three alternatives for the upper reservoir are described below.

Iron Mountain Alternative

    (1) A proposed 235-foot-high, 1,250-foot-long upper dam located 3
miles north of San Vicente reservoir; (2) a proposed reservoir with a
surface area of 93 acres having a storage capacity of 8,070 acre-feet
and a normal maximum water surface elevation of 2,110 feet above msl;
(3) a proposed 12,300-foot-long, 20-foot-diameter concrete power
tunnel; (4) two proposed 500-foot-long, steel-lined penstocks; (5) a
proposed powerhouse containing two generating units having a total
installed capacity of 500 megawatts; (6) a proposed 3,300-foot-long,
24-foot-diameter concrete tailrace; (7) a proposed 14,000-foot-long,
230-kilovolt transmission line; and (8) appurtenant facilities.

Foster Canyon Alternative

    (1) A proposed upper dam approximately one half mile north of San
Vicente reservoir; (2) a proposed upper reservoir with a surface area
of 100 acres normal maximum water surface elevation of 1,490 feet above
msl; (3) a proposed 3,000-foot-long, 20-foot-long, concrete power
tunnel; (4) two proposed 300-foot-long, steel-lined penstocks; (5) a
proposed powerhouse containing two generating units having a total
installed capacity of 480 megawatts; (6) a proposed 2,700-foot-long,
24-foot-diameter concrete tailrace; (7) a proposed 9,000-foot-long,
230-kilovolt transmission line; and (8) appurtenant facilities.

The East Reservoir Alternative

    (1) A proposed upper dam approximately 0.8 miles east of San
Vicente Reservoir; (2) a proposed upper reservoir with a surface area
of 60 acres and a normal maximum water surface elevation of 1,600 feet
above msl; (3) a proposed 6,000-foot-long, 20-foot-long concrete power
tunnel; (4) two proposed 300-foot-long, steel-lined penstocks; (5) a
proposed powerhouse containing two generating units having a total
installed capacity of 570 megawatts; (6) a proposed 2,600-foot-long,
24-foot-diameter concrete tailrace; (7) a proposed 15,000-foot-long,
230-kilovolt transmission line; and (8) appurtenant facilities.
    The proposed project would have a maximum estimated annual
generation of up to 1,000 gigawatt-hours, which would be sold to a
local utility.
