WATER RESOURCES TECHNICAL REPORT−Water deliveries from the Conejo Creek Diversion Project (4,000 AFY) added asadditional in-lieu water deliveries to offset pumping demand in PTP and PVCWDwells.• FCGMA Cutbacks. Adding the final 10 percent FCGMA cutbacks to M&I wells withinthe FCGMA boundary, 5 percent in 2005 and 5 percent in 2010. This replaces thereduced pumping in Scenario 3 of the Inland Saline Intrusion Assessment Project, whichassumed an 8 percent weighted average cutback over 30 years to reach the full pumpingallocation cutback of 25 percent over this simulation period• Supplemental M&I Water Program. Adding the Supplemental M&I Water Program forthe O-H System. This program is described in Section 3.0 and involves delivering anestimated 4,000 AFY of water from the El Rio wellfield, which consist of Conejo Creekcredits, to PVCWD in lieu of groundwater pumping. These deliveries would be madeduring wet and average years as groundwater level conditions dictate in the Forebayarea. It is assumed that an average of 4,000 AFY are delivered over the 31-yearsimulation period, which would result in 5,167 AFY being delivered during the 24 wetand normal years and no deliveries in the dry years. It is assumed that water is pumpedfrom the following El Rio wells.Groundwater Recovery for the M&I ProgramWell1. El Rio # 152. El Rio # 53. El Rio # 64. El Rio # 75. El Rio # 116. El Rio # 87.

Three scenariosare developed (1a, 1b, and 1c) to meet this objective. These scenarios are described below.Scenarios 1a and 1bScenarios 1a and 1b consist of the following:• Groundwater Recharge. 2,814 AFY of recycled water are equally delivered foragricultural irrigation to growers along the OVMWD Ocean View pipeline that pumpW112003002SCO LW1458.DOC/ 033390002 74
