Lee Higgins -2 - 25 January 2011 <br /> Chevron <br /> Catellus Property <br /> An ecological screening evaluation indicates that six threatened or endangered species were <br /> identified in the vicinity of the Site including two sightings of Swainson's hawk that were within <br /> a one-mile radius. The property is within the sphere of influence of the 2004 City of Tracy <br /> General Plan which indicates the area of the Site will be developed for industrial, commercial <br /> and office uses near California Interstate 205. There will be some low-density residential <br /> developments further from the highway. SAIC concluded that future development is not likely <br /> to provide adequate habitat for the hawk or the other species noted in the vicinity. <br /> SAIC concluded that no remedial action is necessary to protect human health or ecological <br /> receptors, and that a decision for no further action determination could be made. <br /> Based on a review, Central Valley Water Board staff has the following comments: <br /> • Consistent with other OVP/TAOC sites, a Soil and Groundwater Management Plan <br /> (SGMP) needs to be submitted. <br /> • Central Valley Water Board staff concurs with the findings of the HHSE and related <br /> supporting documentation, and that the Site is a candidate for closure. A request for a <br /> No Further Action Required (NFAR) determination may be prepared. <br /> • Documentation to support a NFAR closure determination should be completed in <br /> accordance with California Regional Water Quality Control Board, Central Valley <br /> Region's 16 April 2004 update to Appendix A of the Tri-Regional Board Staff <br /> Recommendations for Preliminary Investigation and Evaluation of Underground Tank <br /> Sites - No Further Action Requests. Section 6.5 - NFAR for Cases Exceeding Water <br /> Quality Objectives should be followed for documenting Site conditions. <br /> By 30 May 2011, please submit the SGMP and documentation to support a request for NFAR <br /> determination. <br /> If you have any questions or comments, please call Dean Hubbard at (559) 445-5179. <br /> SHELTON R.
