Cotulla <br /> San Joaquin County <br /> Public Health Services <br /> Environmental Health <br /> 1601 East Hazelton Avenue <br /> Stockton, California 95201 <br /> Dear Ms. Cotulla: <br /> We are in the process of revising the remediation plan we submitted on March <br /> 23, 1989, both to address the concerns raised in your October 10, 1989, <br /> response to the plan and to accomodate changing site conditions. <br /> Based on recent monitoring data, water levels have decreased to the point that <br /> several of the existing monitoring wells at the site are now dry. It is <br /> likely that hydrocarbons previously in the groundwater have been stranded in <br /> the soil . In addition, we wish to avoid delaying further the installation and <br /> operation of a remediation system by eliminating the need for an NPDES <br /> permit. Consequently, we are revising the plan to include proposals to <br /> satisfy the concerns you have raised and to address the fluctuating <br /> groundwater table. <br /> We will submit the revised Problem Assessment Report to your office and RWQCB <br /> by February 16, 1990. Please contact me at (713) 656-7755 if you have any <br /> questions about this site. <br /> Sincerely, <br /> JKH:sg <br /> 7514D <br /> OVERNIGHT MAIL <br /> c - Mr. J. R. Hastings <br /> Mr. L. W.
