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 Chapter 1 Introduction The purpose of the Drought Managanent Plan (PMP) i8 to r8tablieh a oat of oprrating procedures for implmmentation during a mupply shortage in calendar year (CY) 1995 that will have the laast impact on ratafl GUEI~OIPI~S. With atate rassrvoir levels projected to be 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. Manageasnt Plan will incorporate operational objectfves for water supplies in rsurplus as well as shortage conditions. The Resource I Tha DMP procedures will take into account both Metropolitan and regional supplias and demands. pha1m8 will bm used in the DMP with the final phare being the fmplemmntatfon of mandatory stages of the Incremental Interruption and Conservation Plan (IICP).

Certifications are due three business days after the end of the working manth in order to be processed in that month's invoices. -27- DRAFT In-lieu deliveries to storage under the IICP 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.
