RECOMMENDED ACTION:
Approve by minute motion:
1. Approve in concept expansion of the Shadowridge Water
Reclamation Plant (Buena Sanitation District) from 1.0 MGD
1.78 MDG and,
2. Agree to participate in and, if necessary, fund a
proportionate share of the costs of a reorganization
study of the Joint Advisory Committee and the Encina WPCF.
ITEM EXPLANATION;
The above items were brought before the JAC at its meeting of
January 28 and the JAC requested that the respective Councils
and Boards indicate approval before proceeding. A short
recapitulation of the issues is:
1. Buena has requested approval in concept of its proceeding
to expand the Shadowridge Reclamation Facility from 1.0
to 1.78 MGD capacity. The Shadowridge facility does not
process the solids from its sewage but transports them
to Encina for processing. This results in an "enriched"
effluent which has the solids equivalent to a higher
normal flow. Encina was sized and funded based upon
liquid flows (expressed as million gallons per day).
Current capacity is 22.5 MGD although the digesters
which process the solids can process up to 26 MGD of
normal solids. The Shadowridge increase in solids may,
at some future time, exceed its ownership right (4.6%)
of the digester capacity. Buena has agreed to either
acquire additional solids capacity as part of the next
expansion or procure excess solids capacity from some
other agency. The best alternative will not be known
until the completion of the Facilities Plan (sometime
in July-August 1987); however, Buena desires to proceed
with its planning at this time. Solids resulting from
this expansion will not be sent to Encina for at least
four years and it is reasonable to believe that capacity
will be available for them at that time. It is recommended
that Council approve this matter by minute motion.
2. JAC has discussed and undergone some reorganizaton in the
past ten years. Leucadia County Water District, the
present administrator, believes that a further reorgani-
zation of the facility is warranted at this time. The
Leucadia directors cite a slow decision-making process
which requires unanimous agreeement of all six agencies
for changes to the basic agreement, all appropriations
and policy matters and the fact that two-thirds of its
board meeting time is devoted to Encina matters, as reasons
for further reorganization study. Leucadia is proposing
that a scope of work be developed by the Plans and Policies
Committee for approval at the March JAC meeting. It is
recommended that participation in the reorganization
study be approved.

The following are items of Council interest which were discussed at the
JAC meeting:
1. The contract for development of the Faciities Plan was awarded to
Corolla Engineers and should be complete by July, 1987.
2. Mr. Mamaux will serve as Carlsbad's representative to the Budget
Advisory Committee.
3. The Solids Management Study should be complete by mid-February.

SUBJECT: Expansion of Buena's Shadowridge Water Reclamation
Treatment Facility from 1.0 mgd to 1.78 mgd
Dear JAC Representatives:
The Buena Sanitation District is requesting JAC agencies' approval of a
0.78 mgd expansion to its Shadowridge Water Reclamation Facility. This
request is in accordance with Section l(a) of the Twenty Seventh (27th)
Supplement, since the proposed expansion will eventually result in solids
being treated in Unit I of Encina.
If there is the need to acquire additional solids capacity at Encina, we
would recommend that Buena pay its fair share for this capacity. This is
an uncertainty at this time. However, the Phase IV Study, which is to be
completed in June, 1987, will define the present solids processing
capability at Encina and the proportionate solids capacity of each agency.
After reviewing this matter, the Technical Advisory Committee (TAC)
members concluded that the proposed expansion be approved in concept at
this time. Final approval is to follow the completion of the Phase IV
Study. At that time, a good faith review may be in order for the
provisions of the 27th Supplement.
Therefore, on behalf of the Buena Sanitation District, it is requested
that each agency approve in concept the Shadowridge expansion with final
approval being subject to solids capacity requirements determined by the
Phase IV Improvements Study.
