BROADWAY SITE CODE : 2577 <br /> STOCKTON <br /> we are in receipt of your October 24, 1994 letter requesting <br /> guidance for the investigation of your previously leaking <br /> underground petroleum storage tank. <br /> San Joaquin County Public Health Services, Environmental Health <br /> Division (PHS-EHD) once again will provide you with the <br /> appropriate information you have requested. <br /> On November 5, 1992 you were sent an official notification (NOR) <br /> that your site has been assigned to the Local Oversight Program <br /> (LOP) which informed you that the "Regional Board Staff <br /> Recommendations" , "Appendix All , and the LUFT Manual were to be <br /> used as guidance documents for the preparation of workplans and <br /> reports . <br /> On August 29, 1994 I personally explained these documents to you <br /> at the counter in my office and gave you copies of all but the <br /> LUFT Manual . You were instructed to contact the Central Valley <br /> Regional Water Quality Control Board (CVRWQCB) to obtain your own <br /> LUFT Manual . <br /> Within these documents are the details you have requested and <br /> although PHS-EHD can assist you obtaining these documents and <br /> comment on your workplans and reports, we cannot act as your <br /> consultant . <br /> Sites with documented groundwater contamination shall conform <br /> with the requirements listed on page 51 of the LUFT Manual . Some <br /> of these requirements include the placement of a minimum of three <br /> groundwater monitoring wells in order to determine the hydraulic <br /> gradient . If these three wells do not offer a "zero-line" of the <br /> groundwater contamination, then a step-out process of additional <br /> wells are required until the contamination plume of both soil and <br /> groundwater can be identified. <br /> A Division of San Joaquin County Heaith Care Services <br />
