Document Description
The Proposed Project would be constructed in two phases. Phase 1 involves construction of a 50-acre (1,000,000 cubic yard or “CY”) Class II Landfill, known as the Aerojet Waste Consolidation Unit (AWCU or Phase 1 AWCU), on top of the existing non-operating WRND. The existing non-operating WRND is an approximately 100-acre dump located within the ±250-acre WRND parcel. The Phase 1 AWCU would accommodate 1,000,000 CYs of “Transfer Material” excavated from within the AWCU Service Area, defined as the access-controlled 8,500-acre Aerojet Sacramento facility Phase 1 also includes transportation of approximately 500,000 CY of Transfer Material from the existing Aerojet Landfill consistent with the separately approved Aerojet Landfill Clean Closure Plan and amendment of the Aerojet Landfill approved CCP offsite haul route. The remaining 500,000 CY capacity of the Phase 1 AWCU would be filled with Transfer Material from other locations within the AWCU Service Area. These additional projects would be required to evaluate environmental impacts associated with excavation and loading of the Transfer Material; however, the benefits to the environment of transporting Transfer Material from other excavation sites within the AWCU Service Area to the AWCU, placement of that Transfer Material into the AWCU, and capping and monitoring that Transfer Material are included in this analysis. Phase 2 involves construction of the WRND Cap (Phase 2 Cap), an approximately 50-acre cap on top of the remaining WRND that was not capped by the AWCU under Phase 1, and official closure of the WRND consistent with Title 27 requirements. Any portion of the AWCU that has been utilized or constructed and not filled at the time final closure of both the AWCU and WRND, will be closed under the Phase 2 project that caps the WRND. All other areas of the AWCU that have received wastes will be closed under the Phase 1 project.
