The letter responds to our request for a site status update for the aboveground tank spills at the Hamilton City and Tracy sites. The letter states that the last correspondence in Holly's Tracy files is a proposal to perform leachability testing in soils. Holly states that a work plan will be submitted if this is a preferred course of action. Holly should review the case files for the Tracy site and compile a thorough site summary, including historic soil and groundwater data collected. Once we have reviewed the site summary and available data, I will contact Holly to set up a meeting to discuss the site status and additional work(if necessary). The letter also requests closure for the Hamilton City site and enclosed a brief summary to address requirements outlined in the Table 1 - Checklist of Required Data For No Further Action Requests at Underground Tank Sites (Tri-Regional Board Staff Recommendation for Preliminary Investigation and Evaluation of Underground Storage Tank Sites, referred to Appendix B). In a 21 August 2000 phone conversation with Ms. Anne Ogrey of Spreckels, I informed her that staff was not able to evaluate the closure request because the information provided is vague and references historic reports dated in the early 1990s, which are not readily available. Holly needs to prepare a comprehensive closure request report, which should: (1) Recap the historic information and work performed at the site; (2) Present a tabular summary of all historic data collected; and (3) Provide rationale for the closure request. Also, Holly should sample the existing wells to support the closure request. The closure request report should include, at a minimum, the information required in Appendix B.
