As discussed in our June 24, 1996 meeting, the DTSC <br />and RWQCB have identified several comments that need to be <br />addressed in a revised Report. Following are DTSC comments and <br />enclosed are RWQCB comments that must be addressed prior to the <br />Report being approved: <br />1. The Report is missing a signature page showing who at CH2M <br />Hill prepared and approved the document. Please be aware <br />that all final technical workplans and reports must also be <br />signed and stamped by a registered Engineer or Geologist (as <br />appropriate) registered in California. <br />2. Conclusions made in Section 4.0 must discuss the level of <br />fulfillment of goals and objectives, remaining data gaps, <br />and options for addressing data naps and meeting goals. All <br />conclusions made must be adequately supported by conclusive <br />data clearly presented in the Report. Recommendations made <br />in Section 5.0 must include proposals for addressing data <br />gaps and fulfilling goals. As discussed in your Report, <br />during the Phase IV fieldwork, soil and groundwater <br />contamination has been detected in Area II. The Report <br />states that previously existing off-site industries may be <br />contributing sources, but does not provide adequate data to <br />support this conclusion. The Report also fails to provide <br />recommendations to collect any additional information to <br />properly define and address the newly discovered <br />contamination in Area II. <br />FA � d) <br />c:\FA07W.076 <br />is <br />Primed On Recycled Pape( <br />
