1805 Harbor, Stockton <br /> Continental Grain, Page 2 <br /> A separate site assessment investigation was performed by Kleinfelder in October 1999. <br /> PHS/EHD recommends reviewing the report of the site assessment as the information <br /> may be pertinent to your investigation. <br /> The vertical definition of the plume has not been defined. PHS/EHD recommends an <br /> addendum to the above-referenced work plan that will define the vertical extent of the <br /> contamination in both soil and groundwater. Instead of delaying the proposed work <br /> because BSFN has not granted permission to drill on their property, PHS/EHD <br /> recommends modifying the location of the exploratory borings and monitoring wells <br /> to Harbor Street. The work plan addendum should also include a proposal to conduct <br /> a 2000 feet well receptor survey in accordance with Appendix B of the Tri-Regional <br /> Board Staff Recommendations. All wells identified in the survey and the <br /> location/addresses on a map along with any known construction details of the wells <br /> should be provided. Submit a work plan addendum to PHS/EHD by April 1, 2000. <br /> E Work should commence no later than May 1, 2000. <br /> Please feel free to contact Jeffrey Worig at (209)468-0335 if you have any questions. <br /> Donna Heran, RENS, Director <br /> Environmental Health Division <br /> JJeffrey Wong , REHS Margaret agorio, REHS <br /> LOP/Site Mitigation Unit IV Supervisor <br /> c: RWQCB, Central Valley Region -Marty Hartzell <br /> c: Additional Responsible Party: Penny Newman Grain, 1805 Harbor St., <br /> Stockton, CA 95203 - Robert Mentelos <br /> fax: ATC Associates, Inc. - Drew Van Allen <br />
