LFR Inc. The "Water Quality Control Plan, Sacramento River and San Joaquin River Basins" (RWQCB 1998) designates beneficial uses, establishes water-quality objectives, and contains implementation plans and policies for all waters of the Basin. The designated beneficial uses of the groundwater, as specified in the Basin Plan, are domestic and municipal, agricultural, and industrial supply. Two production wells are located at the Site (PW-1 and PW-2; Figure 3). PW-1 is screened from 150 to 215 feet bgs. PW-2 was installed by the previous property owner and the screened interval is not known; however, the pump was set at 130 feet bgs. Based on review of California Department of Water Resources (DWR) well logs, there is one well (screened from 170 to 230 feet bgs) located at the adjacent and downgradient Teichert Aggregate facility. 5.0 SUMMARY OF WORK COMPLETED This section provides a summary of the site activities conducted during January 2003 through May 2006. 5.1 CEQA Initial Study LFR prepared a CEQA IS (LFR 2003c) for the Site on behalf of the CIWMB and DTSC in accordance with the California Environmental Quality Act (§ 21000 et seq., California Public Resources Code) and implementing Guidelines (§15000 et seq., Title 14, California Code of Regulations). Based on the results of the IS, the DTSC Branch Chief determined that the proposed project "could not have a significant effect on the environment and that a Negative Declaration would be prepared pending the implementation of proposed conservation measures provided in the IS." The proposed conservation measures were incorporated into Section 7.2.4 of the RAP and a Negative Declaration was prepared and signed by the DTSC on July 22, 2003. A copy of the Negative Declaration is included in Appendix C of the RAP, which can be found in Appendix A of this report. 5.1.1 Air Quality Conservation measures, consisting of dust control via water truck and/or hose spray, were implemented to comply with the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) Regulation VIII Control Measures for construction emissions of PM-10 contained in Table 8021-2 of the 2001 SJVUAPCD Rule 8021 "Construction, Demolition, Excavation, Extraction, and other Earth Moving Activities" guidance (adopted November 15, 2001), as applicable. It was agreed with the SJVAPCD that a formal Dust Control Plan would not be required. However, extensive air monitoring and dust control measures were implemented during removal activities. Details regarding these guidelines are provided in Section 7.2.4 of the RAP. rpt-RA_summ-Nov06-fina1-09025 Page 11
