PRO RAM 4 • ' In response to the issues outlined in the RFP, PMC has provided a detailed scope of work, which reflects the needs of the San Joaquin County, our understanding of the tasks to be undertaken, and the work products to be delivered. PMC, in our association with other knowledgeable and experienced consultants described in the Project Team section of this ! proposal, will prepare a project-level Environmental Impact Report for the DeSilva Gates project. PMC anticipates that the EIR process can be completed within 32 weeks for a cost �[ of$199,650. E The Environmental Impact Report.(EIR) for the proposed project will be prepared in accorda.nce.with the current State Guidelines for implementing the California Environmental ., l Quality Act (CEQA) The EIR will discuss the potential environmental effects associated with 'C"construc ing'and operating the DeSilva Gates Quarry, including effects of groundwater extraction on nearby farms and the California Aqueduct system,'increase in'truck traffic'and related diesel emissions, noise associatedwith operating the aggregate processing facility, and the loss of Prime Farmland for 40 years during quarry operations and reclamation of the site back to agricultural uses. �i In preparing the EIR, the project team will work closely with San Joaquin County and � J interested agencies, other consultants, responsible agencies, boards, or concerned parties to ensure that the EIR accurately describes the projects' significant impacts. In this regard, the EIR is intended to document the potential impacts of the DeSilva Gates project. PROJECT UNDERSTANDING The proposed project is the preparation of an Environmental Impact Report (EIR) for the DeSilva Cates project located west of_ caster,Road between Vernalis'Road (State Route 132) t fand�Blewitt Road,.east,of the Delta Mendota Canal and southeast of Tracy.' The project includes a Quarry Application for the establishment of a new aggregate quarry and processing facility and reclamation plan. The quarry would extract 20 million cubic yards of f aggregate over forty years in four phases. Approximately 750,000 tons of aggregate would be extracted annually. Extraction would occur in two pits, the South Pit and North Pit. In the first phase, the South Pit would be excavated to design depth and the first stage of the North Pit would be excavated to 20 feet. Water from the South Pit would be stored in Stage 1 of the North Pit. In the second phase, North Pit (Stage 1) would be mined to design depth and the South Pit would be backfilled to 15 feet above groundwater and groundwater would be stored in the South Pit. The third phase includes mining Stages 2 and 3 of the North Pit to design depth and backfilling Stage 1 of the North Pit to 15 feet above groundwater. F Topsoil would be replaced in Stage 2 of the North Pit and groundwater stored in the South Pit. The final phase would keep Stage 3 of the North Pit as a pond for agricultural use and �- backfill Stages 1 and 2 of the North Pit to 15 feet above groundwater. The South Pit would also be backfilled to 15 feet above groundwater and the topsoil replaced. The aggregate mining would occur as either a "dry pit operation," where water in the pit [. would be pumped to another pit so only dry materials are excavated, or as a "wet pit operation" with mining activities occurring below the water table. The EIR will analyze each type of operation. The reclamation plan proposes two options 1) reclaim the majority of the site to agriculture through backfilling the North Pit to 90 feet above mean sea level, then replacing topsoil on 7 ! Stages 1 and II for agricultural use, and backfilling the South Pit to grade, or 2) reclaim North �L Pit Stages 1 and II to agriculture, backfill the South Pit to grade, and use North Pit Stage III as an agricultural storage pond.
