Gail Wiggett <br /> August 14, 1996 <br /> Page 3 <br /> implement a subsurface investigation or, long-tern pumping of groundwater on the levee due to the <br /> indemnification requirements of Reclamation District#548 (RD#54.8). The RWQCB advised Tower Park to <br /> concentrate on remedial alternatives, such as bioremediation,that did not require intrusion in the levee. <br /> As discussed ui a July 23. 1996 telephone conversation with you,based on the indemnification requirements of <br /> RD #548. we do not believe that it will be possible to implement additional remedial activities that require <br /> subsurface trenching, boring and/or active soil vapor/groundwater extraction on the levee. .SECOR has placed <br /> a call to Mr. Robert Sternfels of RD 4548 to verify that their indemnification requirements are unchanged;we <br /> have not vet heard back from Mr. Sternfels. <br /> As indicated in.S'ECOR's Quarterly Groundwater Monitoring Report,First Quarter 1996 a Risk-Based Corrective <br /> Action (RBCA) approach would like to be pursued for the Site. We understand that specific guidance has not <br /> vet been developed by the RWQCB for this corrective action approach. Thus,we plan to defer a RBCA-approach <br /> wail the appropriate RWQCB guidance is available. If you have any questions or require additional information, <br /> please do not hesitate to contact us at(4 15) 882-1548. <br /> Sincerely. <br /> ED GFS <br /> SECOR International Incorpora 5�P��W.Mpo OCA <br /> No. 6197 � � <br /> Donald W.
