ENCINA WPCF SHORT TERM
CAPACITY MANAGEMENT POLICY

RECOMMENDED ACTION:
Council approve by minute motion the proposed Encina WPCF Short Term Capacity
Management Policy.
ITEM EXPLANATION:
In comparing existing capacity ownerships and agency flows, the Encina Joint
Advisory Committee (JAC) became concerned about the availability of treatment
capacity at Encina through construction of the Phase IV expansion. To address
this concern, JAC retained a consultant to develop a short range strategy to
insure capacity availability for all agencies through construction of the
expansion.
The attached policy continues historic practices at Encina with the exception
of the capacity monitoring program. In the past, Encina has monitored only
actual flows. Under the new program, capacity will be monitored on flows and
permit commitments issued.
Under the new policy, when an agency's flow commitments reach their capacity
ownership, they are required to report to JAC how they propose to provide for
future capacity within their jurisdiction.
FISCAL IMPACT:
None.

PURPOSE - To establish a policy minimizing the disruption of
wastewater service in the Encina service area prior to
the completion of Phase IV.
BACKGROUND - The Encina Phase IV Expansion Project is scheduled for
completion by mid-1991. A short term capacity manage-
ment study was accepted by the Encina Joint Advisory
Committee (JAC) on September 7, 1988. That study exa-
mined the Encina service area treatment needs over the
short term, i.e., until the completion of Phase IV. The
report concluded that given the current situation, there
should be sufficient treatment capacity within the ser-
vice area until mid-1992; after that, the Phase IV
capacity would be used. However, individual agencies
may face capacity shortfalls and/or present trends may
change significantly, and a basin wide shortfall could
occur prior to the completion of Phase IV. Upon exa-
mining the situation on capacity, the member agencies
set the following policy:
POLICY - 1. The agencies shall agree to present to JAC, the
method or methods to be utilized by such agency(s)
to meet future commitments, when an agency's
monthly flow plus its commited flows (commited
flows are calculated using an agency's planning
flow per EDU) reaches its owned and leased
capacities.

2. Interagency lease agreements and/or permanent
exchanges of Encina capacity shall continue to be
the method of meeting individual agency shortfalls.
3. When the Encina service area flows reach 26.5
million gallons per day (MGD) on a monthly basis the
member agencies will consider the following correc-
tive action after due consideration is given to the
estimated Phase IV completion date:
A. Curtailment of all groundwater clean ups and
acceptance of septage discharges at the Encina
plant.
B. Restricting Oceanside flow to that from the
"Wilcox Triangle Area".
C. Transfer ing a portion of Vista's flow, origi-
nating in the Encina service area, to Oceanside.
D. Activation of the Calavera Hills treatment plant
to its maximum liquid and solids treatment
capacity.
E. Rehabilitation of the anaerobic digester at the
Gafner Treatment plant to obtain additional
solids treatment capacity.
F. Other options, including direction of member
agency flows to treatment plants outside the
service area.
4. The member agencies shall provide on a monthly basis
to the EAA:
A. A total count of connected EDU's

B. A total EDU count of legally binding commitments
to serve and the estimated schedule of actual
flow associated with the commitments.
5. This policy shall expire upon completion of the
Phase IV project.
