AGENDA TOPICS
1. Chairman Monroy introduced the meeting minutes of March 29,
1990, which were subsequently reviewed and approved by the
Committee members.
2. Proposed SDG&E Expansion at Encina:
a. The Committee noted the details of the May 10, 1990, tour
of the Encina Power Plant and public hearings that follow.
San Diego Gas and Electric will provide a bus leaving at
1:00 p.m. from City Hall for an hour tour of the Encina
facility. At 2:00 p.m., the bus returns and the
California Energy Commission will open its public hearing
on the proposed expansion. The Commissioners will stay
until all testimony regarding the Encina site is received.
b. Chairman Monroy indicated that he has received copies of
State Attorney General's Office Opinions regarding the
issue of ownership of Agua Hedionda Lagoon. An issue
regarding the underlying ownership of the lagoon by the
State of California and not SDG&E appears to be
developing. Chairman Monroy will be conducting other
research into this issue and speaking with State and local
officials regarding this subject.

c. Chairman Monroy discussed some areas of concern that are
not addressed in San Diego Gas and Electric's application
for the Encina plant expansion:
1) Discharge Volume
SDG&E is currently allowed to discharge up to 800,000
gpm (gallons per minute) of sea water. However, prior
studies on the environmental effect of cooling water
discharge were based on a 150,000 gpm rate. SDG&E
should update their studies to reflect current
discharge rates. There is the potential for
additional impacts to the long shore transport system.
2) Fish Kills and Kelp Damage
SDG&E's application does not offer a method for
mitigating the destruction of kelp and sea life caused
by increased thermal discharge into the ocean.
Additionally, increased water volumes into the western
basin of the lagoon may increase the fish kills at the
plant.
3) Lagoon Siltation
There appears to be some circumstantial evidence that
the cooling water demand from the proposed power plant
addition will increase the rate of siltation of the
Agua Hedionda Lagoon. One study found that no sand
bars existed in the west end of the lagoon prior to
the previous Unit 3 and Unit 4 expansion. Current
sand studies identify scour holes produced by the
intake of cooling water. The volume of the sand bars
is approximately the same as the scour holes. No
causal relationship has been established between the
formation of the holes in the lagoon bottom and the
lagoon sand bars, but the matter should be addressed
by SDG&E in their application.
d. It was reported that the City of Carlsbad is hiring a
series of consultants to identify legal and environmental
issues to challenge the NOI application.
e. It was moved, seconded, and was unanimously approved to
appoint Mario Monroy as spokesman for the Beach Erosion
Committee in the NOI hearing.

3. New Business and Announcements
a. Pearl Johnson shared information and old photographs that
suggest over the past one hundred years the lagoons in
North San Diego County are slowly drying up. Pearl also
mentioned that Councilmember Ann Kulchin would forward
material from BEACh to the Beach Erosion Committee.
b. Pearl Johnson also provided some information from previous
studies to the Committee regarding electromagnetic
radiation from transmission lines including power
generating facilities and transfer stations.
c. Tekmarine will have the April sand survey results
available for discussion at the next Beach Erosion
Committee meeting. Because SDG&E is scheduled to dredge
the Agua Hedionda Lagoon this fall or winter, additional
surveys will be recommended for "before" and "after" sand
conditions.
d. The next meeting date was set for June 28, 1990.
The meeting was adjourned by Chairman Monroy at 7:40 p.m.
Discussion items will include the spring sand survey, an update of
the NOI process, and the new draft of the Batiquitos Lagoon EIR.
