Grantline. <br /> During the investigation of the above site, contamination was confirmed in the area of <br /> the tank location. Due this new leak source being identified, these tanks would have to <br /> be replaced due to the inability to reline the tanks to stop leakage. The relining of tanks . <br /> is prohibited by-CCR title 23 Section 2661 (c). <br /> The lateral and.vertical extent of soil and groundwater contamination found at this'site <br /> must be defined. Remedial alternatives must be evaluated and the most cost effective <br /> alternative implemented. It has been demonstrated that excavation/removal of <br /> contaminated soil is an effective remedial alternative in this area of Tracy. Our agency <br /> recommends that contaminated soil be excavated, immediately after the existing <br /> underground storage tanks (UST's) have been removed, as an interim remedial action. <br /> A plan for this work must be submitted to our agency. We will conduct public notification <br /> prior to approval of the work plan. The owner or operator of the UST's should complete <br /> a State Water Resources Control Board Petroleum Underground Storage Tank Cleanup <br /> Fund application and obtain preapproval from them for the costs of the investigation and <br /> remediation work performed at this site. <br />{ If you have any further questions regarding this matter, please contact Harlin Knoll, <br /> Senior REHS, at (209)468-3442 concerning any site investigation and remediation <br /> information, or Doug Wilson, supervising REHS, at (209)468-3446 for information <br /> t concerning permits and inspections for underground tanks. <br /> k <br /> Karen Furst, M.D., M.P.H. <br /> Health Officer <br /> Doug son, Supervising R.E.H.S. <br /> Environmental Health Division <br /> t DW/dw <br /> ' A Division of San Joaquin Counry Health Care Services <br /> i <br />
