Von Sosten Road <br /> Our meeting of Wednesday, October 9 1991, proved to be very beneficial in that all parties will continue <br /> to work cohesively toward our goal of restoring groundwater quality. <br /> 4 <br /> In summary and in reply to your letter of,,October 2, 1991: <br /> 1� <br /> San Joaquin County Public Health�Services,Environmental e ivision HD and Central <br /> Valley Regional Water quality Control Board (CVRWQCB) have determined that additional <br /> monitoring wells are needed to further characterize the Larnmersville School underground storage <br /> tank site. The purpose being to better define the groundwater contamination and aid in the <br /> development of a remediation action plan. PHS/EHD evaluation of work plans can be accomplished <br /> within 30 days of receipt. The evaluation process for reports of completed field activity may vary <br /> between 30 - 90 days, which is dependent upon staff workload and the report contents. <br /> Responses from CVRWQCB repres'entativi, Elizabet Thayer, may take considerably longer due to <br /> her prohibitive workload. In order to maintain continuity,however,we do not anticipate the need <br /> to await CVRWQCB comments prior to preparing our response at the conclusion of our evaluation. <br /> CVRWQCB comments will be necessary at the. time of final remediation and during request for site <br /> li <br /> closure. <br /> IF <br /> Groundwater Technology, Inc. (GTI) has submitted a work plan for additional monitoring wells. <br /> GTI will prepare an Interim Remediation Plan to ad ss the groundwater contamination during the <br /> next phase of field activities. <br /> As discussed, prior to the commencement of any corrective action/cleanup activities, a period of <br /> public notice must be given. We will pursue the pos ibility of utilizing the school board as a means <br /> of providing the required public notice. <br /> During the required notice period of 30 days, pilot testing of the proposed remedial action may be <br /> conducted. The compilation of 'pilot test data provides GTI with verification that the proposed <br /> system will perform satisfactorily: <br /> itA <br /> A DiNision 06an Joaquin County licalth C,tiervjccs <br /> I` <br />
