Improvements on the project site include a residential house and barn located on the privately-owned parcels off South Costa Ranch Road (formerly Koster Road). Other improvements include a mobile home and outbuilding located on the north side of Hospital Creek and two mobile homes located south of Hospital Creek. The house and barn would be relocated to another location on-site before mining occurs at their existing location. The mobile homes and outbuilding will be removed. The specific purposes and objectives of the Applicant in implementing the Proposed Project include: • Provide a reliable source of construction aggregate for the San Joaquin County and Stanislaus County areas. • Replace depleted resources at the Applicant's Tracy facility. • Provide a full range of aggregate products from one location. • Retain company employment associated with aggregate extraction and processing. • Maximize use of existing aggregate processing facilities and investments. For example, some of the aggregate plant processing equipment currently located at the Applicant's Tracy aggregate plant will be relocated to Vernalis when processing is discontinued at Tracy. Some of this relocated equipment will consist of scrubbers, coarse and fine material washers, dewatering screens, radial stackers, etc. • Retain company position and market share as a leading regional aggregate provider. Provide economical ready mix concrete and asphalt for the local market. • Recycle broken concrete and asphalt pavement into base material rather than having this material go to a landfill. Proposed Project Components The Applicant proposes to conduct a phased mining program that would excavate pit run material and convey it to an on-site central processing plant. There will be eight phases, with each phase mined separately and in a different location on the project site. In addition to mining, PhaseVlll will include the initial, up-front installation of the processing plants, scales and other facilities. Mining will begin with Phase I, and once Phase I is completed the extraction would proceed to Phase II and continues in numerical order until Phase VIII is mined. Refer to Figure 3-3 for the proposed mining plan (Option 1) and the location of the separate phases. Silt products from the plant would be discharged into silt ponds. Phase VII will be used as a temporary silt pond until Phase I mining is completed. At that time, the silt pond will be moved to the eastern portion of Phase I, and mining will continue with Phase II and progress in order. All disturbed surface runoff would either be directed to silt ponds or contained within the mining excavation. Reclamation will also follow in the mining order, starting with Phase II (Phase I will be reclaimed when mining is completed and the silt pond is no longer necessary).
