ISfi�IIC RGG�AAi <br /> RE: California Highway Patrol SITE CODE: 1904 <br /> 385 W_ Grant Line Rd. <br /> Tracy, CA <br /> San Joaquin County Environmental Health Department (EHD) has not been informed of or <br /> received any reports of quarterly monitoring of the monitoring wells at the above referenced site <br /> since the URS Corporation report dated December 7, 2000, for water samples collected October <br /> 31, 2000. On January 25, 2002, END directed that the monitoring wells at this site be placed on <br /> a quarterly monitoring schedule immediately, that a quarterly report be submitted to EHD by April <br /> �. 1, 2002, and that the'water samples from the monitoring wells be analyzed for total petroleum <br /> hydrocarbons as gasoline, benzene, toluene, ethyl-benzene, xylene and 5 oxygenates (MtBE, <br /> DIPE, TAME, ETBE, TBA) using appropriate EPA Methods. Compliance with this directive has <br /> not been accomplished. <br /> L <br /> In addition, the work approved by EHD in March 2001, to investigate the lateral and vertical <br /> extent of the groundwater contaminant plume has not been performed. EHD is aware that you <br /> �.. have not been able to gain access to the private property north of this site to perform this <br /> investigation. EHD staff went to the site on March 14, 2003, to evaluate other options after <br /> discussion with State of California General Services Department staff. EHD approves the <br /> installation of the deeper screened monitoring well described in the URS March 16, 2001, work <br /> +� plan on site, west of the above ground storage tank. The information from this monitoring well <br /> and the sampling, monitoring and reporting information from the current on site wells will be <br /> discussed with the Central Valley Regional Water Quality Control Board prior to requiring further <br /> off site investigation. <br /> It has been over 2 years since data has been provided on the contaminant plume at this site. The <br /> above work must be completed by July 15, 2003. <br /> If you have any questions contact me at (209)468-3449. <br /> Donna Heran, REHS <br /> Director of Environmental Health <br /> Margaret Lagorio, Supervising REHS <br /> ' Unit IV/LOP <br /> 1 <br /> V <br /> C: CVRWQCB—James Barton <br /> URS—Philip Cox <br /> Albert & C Navarra <br /> `- CA Dept General Service, James Meda, 707 3rd Street, Suite 4330, Sacramento, 95605 <br />
