INFORMATION
LEAGUE OF WOMEN VOTERS PRESENTATION. Mrs. Skotnicki urged attendance
at the "208" Water Quality Workshop, to be held on Tuesday, August 2,
1977, at the San Diego Hilton, which is being co-sponsored by the
League of Women Voters, San Diego Ecology Centre and the American
Association of University Women. The Workshop will present an ex-
planation of the area-wide management plan which will identify how
this region can meet Federal water quality standards. Lorraine
Boyce, Chairwoman of the CPO Board of Directors will moderate the
Workshop.

INFORMATION (CONTINUED)
3. BULLETIN FROM STATE WATER RESOURCES CONTROL BOARD. Mr. Evans re-
ferred to the bulletin dated June 1977 and stated it is reaffirm-
ing what was already known—that the State grant funds will be
exhausted by late 1977 and we will get no State funds for Encina
Step 2 and Step 3 unless the Clean Water Bond Law of 1978 is
adopted. Supposedly, if the Bond Law is adopted, it will have a
provision for retroactively reimbursing agencies for the 12% per-
cent State grants. Mr. Evans also indicated the Clean Water Grant
program regulations have been revised to give heavy emphasis on
water reclamation.
4. LETTER FROM EPA REGARDING RAQS IMPLEMENTATION PLAN. Mr. Evans
quoted the letter dated July 12, 1977, from the Director of the
Water Division, EPA, San Francisco, addressed to Lorraine Boyce,
Chairwoman, Policy Advisory Committee, San Diego Air Quality Pro-
gram, which reads in part: "EPA is willing to grant approval to
proceed with the design phase (Step 2) of these projects pending
final resolution of the facilities design parameters." ...
"To determine whether construction can proceed (Step 3), we will
review the actual implementation that has occurred." ... Mr.
Evans summed up the letter, stating that the EPA said, "You have
submitted a plan and we don't like it but we are willing to live
with it." Mr. Evans remarked that for all practical purposes we
have cleared the hurdle of providing an Air Quality Implementation
Plan.
5. LETTER TO LEUCADIA COUNTY WATER DISTRICT REGARDING DISCHARGE OF
SECONDARY SLUDGE. Mr. Evans referred to his letter dated July
15, 1977, addressed to Mr. Hanson. He stated that it was brought
to his attention that several years ago a proposal had been made
by the Leucadia County Water District which contained some aspects
of its current plan for reactivating its secondary treatment plant
and storing the treated effluent to be discharged to Encina during
off-peak hours. Mr. Evans said he reviewed previous JAC minutes
and staff reports that had been done relative to the proposal.
He explained that he had met with Mr. Hanson and Leucadia's en-
gineer and it was agreed that some more information needs to be
assembled and evaluated. Mr. Evans remarked that Brown and Cald-
well will be doing a study on this matter as part of Encina's re-
rating. He informed the Committee that he is not recommending
any action at this time but wanted to let the members know that
the plan is being investigated.
6. PROGRESS ON ENCINA RE-RATING STUDY. Mr. Evans asked Mr. Oldsen
to make the report since he has been closely involved in the study.

INFORMATION (CONTINUED)
6. Mr. Oldsen stated they have been working diligently on the matter
and that they have been overwhelmed with many technical problems
while carrying out the test. He said that grease removal is the
problem that they are most concerned about. Mr. Oldsen remarked
that they thought they could transfer the knowledge gained from
the recent San Elijo study to the Encina study; however, there were
numerous problems. He said they continually had problems diffusing
chlorine uniformly. Mr. Oldsen mentioned that the reason it is so
important to accomplish a reduction by chlorination is that chlor-
ination will provide a backup to the present system should operat-
ing at a higher capacity cause deterioration in the effluent quality.
He remarked that the hydraulic testing and chlorination testing in
the sedimentation tanks are running concurrently, providing an ex-
cellent way to measure performance. Once we are certain the sedi-
mentation tanks are satisfactorily handling 16 to 17 million gallons
per day then there are some other steps. For instance, Brown and
Caldwell will evaluate the digester performance and the ability of
the plant to pass peak flows.
Mr. Oldsen explained that the use of chemicals to promote foccula-
tion is not being studied since the minute we start using chemicals
we develop a whole new set of problems.
He also mentioned that the re-rating study at the San Elijo Treat-
ment Plant had indicated that an upgrading from 2 million gallons
per day to 2.7 million gallons per day was in order. Mr. Oldsen
mentioned that the San Elijo re-rating is to be decided at the
Coastal Commission level on the 5th of August. He said the Encina
Plant was, in effect, re-rated when it was expanded from 9.75
million gallons per day to its present capacity during Phase IIA.
Mr. Oldsen said we should not be discouraged—that it is just taking
time.
*****
Mr. Dominguez asked if there was anything being done along the line
of environmental covers for the digesters.
Mr. Evans explained that, at the present time, the program for
alleviating the problem with the digesters involved the bypass of
the steam injection system in favor of a heat exchanger. Brown
and Caldwell, as well as the County Operations staff, feels that
perhaps the steam injection system may be contributing to the foam-
ing problem. Although environmental covers are a possibility, the
cost of such covers and the problems associated with venting them
properly make them near the end of a long line of possible solutions.

REPORTS - ROUTINE
7. OPERATIONS AND MAINTENANCE REPORT.
Mr. Evans reported that we have not had any significant foaming during
the last several weeks. He said we are controlling the odors by re-
ducing the temperature in the digesters.
Mr. Evans indicated that last week the propeller meter was tested
during a period of peak flow. The test results showed that at that
time the control room totalizer was reading 14.6% low. He also said
that if the 14.6% factor were applied to the average daily reading
that result would be extremely close to what we are estimating for
the total plant flow.
Mr. Evans called the JAC's attention to the $500,000 grant from the
State Water Resources Control Board which is available for a water
reclamation study in San Diego County. Mr. Evans said that at this
point it looked like San Diego County would be the sponsoring agency
and would receive the grant but the CPO would be heavily involved
in the project. A discussion took place on the approaching meeting
of the San Diego Region Water Reclamation Study Agency and that
Agency's involvement with this particular grant. It was felt by
several JAC members that the study agency would be the appropriate
sponsoring agency for the reclamation study grant.
(Break. Meeting was reconvened at 10:05 A.M.)
Mr. Evans reported on the staff level meeting with the State Coastal
Commission to discuss the Phase III coastal permit appeal. At that
meeting the Coastal Commission staff indicated that the State
Coastal Commission would not address the issues of air quality or
capacity but would be primarily concerned that the financing of the
Phase III project would not be dependent on the development of pres-
ent agricultural lands, lagoon frontage or bluffs in the coastal zone.
Attorney Gann added that our letter of request to re-open the permit
appeal would emphasize that the proposed expansion complies with the
spirit of the Coastal Act.
8. FLOW REPORTS. Mr. Evans distributed a memorandum explaining how each
agency computes its E.D.U. information. He also pointed out that the
June Flow Report showed that San Marcos County Water District flows
had decreased approximately 20 percent, or 300,000 gallons per day.
9. SULFIDE CONDITION REPORT. Mr. Evans indicated that the sulfide con-
dition of the system seemed to be normal for this time of the year.
Mr. Oldsen said that Leucadia and Encinitas should be congratulated
for their success in reducing sulfides in their systems.

port reflecting operation and maintenance costs through the end of
the fiscal year shows that the total expenditures were $122,000
under the budgeted amount.

tion to purchase a storage cupboard and a work table.

WORK TABLE ($97) AND STORAGE CUPBOARD ($91).
12. MANAGEMENT SUBCOMMITTEE MEETING. The meeting was set for Wednesday,
August 24, following the next JAC meeting.

continue with Brown and Caldwell as the project design engineers was
set for Wednesday, August 3, at 2:30 P.M., in the Encina Conference
Room. Members are Messrs. Schneider, Hanson, McKay, Beckman, Oldsen
and Evans.
The meeting was adjourned at 10:40 A.M. The next meeting is scheduled
