3ECOMMENDED ACTION:
This item is for review and discussion. No action will be taken at this time.
On Monday, August 15, 1994, the San Diego County Water Authority member agency IICP
Advisory Group met to review proposed revisions to the IICP (or Metropolitan Drought
Management Plan). You may remember the IICP is the Metropolitan plan to manage the water
supplies during our most recent drought. IICP stands for Metropolitan’s Incremental
Interruption and Conservation Plan.
Some proposed revisions in the attached will be presented and discussed at Wednesday’s
Commission meeting.
METROPOLITAN'S DROUGHT MANAGEMENT PLAN

Introduction
The purpose of the Drought Managanent Plan

for implmmentation during a mupply shortage in calendar

critical by the end of the year, it io appropriate that
Metropolitan and its Member Agencies be prepared for a
supply shortage,
This IMP ir primarily focused on actions required
for 1995; however, elements of this DMP will be folded into
a more comprehensive Resource Management: Plan.

1 require agencies to
account and certify that they have made operational
chang8s neceerary for such storage, These accounting
and certification processes must take place after the
delivaries have been made, The lag time between deliveries
and certifications typically is aeveral weeks. Because of
this lag it ie not poerible to immediately determine each
agency's performance under the IICP. Thus, a delay in
4 disincentive charges BCCO unt may -
gccur. However the annual reconciliation will
account for any irregularities.
As an example of how scheduled targets ad4he
are determined, consider a hypothetical
agency which utilierd 200 acre-feet (AF) in January of
the base year
The 200 AF is further broken
down to 100 AF of noninterruptible water, 50 AF
of agricultural eervice, and 50 AF of sea water barrier.
Tn Stage V the agency's scheduled target quantity
for January is determined as follows:
100 AF noninterruptibls - 20 percent = 80 AF
+SO AF agricultural - 50 percent = 25 AF
+50 A€ sea water barrier - 58 2p percent = =zf fi
AE
equals scheduled January target quantity = iEW 1-F
Therefore, this agency would be allowed to
purchase a knaxinum of W
under the scheduled target quantities without incurring
AF in January during Stage V
a disincentive charge, Thio amount can be increased at
the discretion of the General Manager through deliveries
of watery made to GOOD- 'v storage -
