BOOZE00 <br /> TED PETERS TRUCKING <br /> PO BOX 831 <br /> MANTECA CA 95336 JUN 2 5 2001 <br /> RE. TED PETERS TRUCKING CO,INC SITE CODE: 1427 <br /> 1985 YOSEMITE <br /> NL NTECA CA 95336 <br /> San Joaquin County Public Health Services Environmental Health Division (PHS/EHD) <br /> has received and reviewed W,,k Plan Well A ban&mlpr dated June 14, 2001 prepared by <br /> Geological Technics,Inc (GTI). The work plan proposed destroying two monitoring wells <br /> (MW-2 and MW-3) at the above referenced site since onlynegligible amounts of gasoline <br /> remain in soil and groundwater. The work plan further proposed retaining MW 1 in order <br /> to support the above ground storage tank investigation. <br /> PHS/EHD does not approve the workplan at this time. Analytical results of MW-1 <br /> samples from the last quarterly sampling collected on May 1, 2000 were 379 micrograms per <br /> liter(�%/1) of Gasoline as reported in GrapxivaterMloruto ngRepon Spring Quarter 2000 dated <br /> August 18,2000 prepared by GTI. The same report concluded that groundwater does not <br /> appear to be significantly impacted. PHS/EHD agrees that the analytical results do not <br /> appear significantly high. Nevertheless, only three quarters of monitoring have been <br /> performed at this site to date. <br /> The monitoring wells were sampled in the months of July(3rd Quarter),November(4th <br /> Quarter), and May(tad Quarter). PHS/EHD req uirAes you to perform three additional <br /> consecutive quarters of sampling beginning in the 3�d Quarter of 2001 to provide at least one <br /> complete annual groundwater monitoring cycle before closure or well destruction can be <br /> considered. <br /> Donna Heran, REFIS,Director <br /> Environmental Health Division <br /> V <br /> Jeffrey Wong, Dot Lofstrom,RG <br /> LOP/Site Mitigation Unit IV LOP/Site Mitigation Unit IV <br /> Cc: CRWQCB, Central Valley Region— Marty Hartzell <br /> Cc: Geological Technics, Inc. -- Ray Kablanow <br /> A Division of San Joaquin County Health Care Services <br />
