The Geological Technics Inc. (GT) correspondence requests an extension to submit laboratory data <br /> and a workplan to further characterize the documented soil and groundwater plume. An extension is <br /> granted, please submit the information requested by October 15, 1999. <br /> The Geological Technics Inc. (GT) correspondence also suggests that"Sinclair already had 3 wells that we <br /> could calculate groundwater gradient with, so surveying MW-4 is not necessary at this time." PHS/EHD <br /> strongly disagrees with your consultant(GT). All groundwater monitor wells must he surveyed and used in <br /> the evaluation of the hydrogeologic setting. Monitor well MW-4 was installed February 16, 1999. The <br /> workplan by Del Tech signed by Ray Kablanow (Registered Geologist, Geological Technics)dated August <br /> 20, 1997 proposed the installation of MW-4. This proposal also included "Surveying of the new <br /> monitoring well will be completed by a licensed surveyor..." This scope of work was approved by <br /> PHS/EHD on September 29, 1997. The consultant has failed to complete this task to date. <br /> On September 16, 1999 PHS/EHD spoke with Mr. Kablanow by telephone after reviewing the September <br /> 15, 1999 correspondence to PHS/EHD informing him of the monitor well surveying requirement. Prior to <br /> the completion and submittal of the next required groundwater monitoring event (QME) report, monitor <br /> well MW-4 must be surveyed and employed in the evaluation of gradient and flow direction. PHS/EHD <br /> now directs the responsible party at this site to complete this task. The next required quarterly <br /> groundwater-sampling event is past due. Please contact PHS/EHD to schedule the next QME. <br /> PHS/EHD strongly recommends that the responsible party at this site routinely request at least three <br /> bids for all scopes of work proposed related to corrective action activities at this Underground <br /> Storage Tank site as required by the Underground Storage Tank Cleanup Fund. All site work must <br /> be approved by PHS/EHD first then cost pre-approved by the Underground Storage Tank Cleanup <br /> Fund (USTCF) prior to commencing work. <br /> Should you have questions regarding this correspondence please contact Ron Rowe at (209) 468-0342 or <br /> Margaret Lagorio at(209)468-3449. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> Ronald Rowe, Sr. REHS Margaret agorio, REHS <br /> LOP/Site Mitigation Unit Supervisor <br /> Cc: CVRWCQB—Mark List <br /> Geological Technics- Ray Kablanow <br /> Del Tech--Don Light <br /> A Division of San Joaquin County Health Care Services <br />
