Main Street ENVIRONMENT HEALTH <br /> Stockton, CA 95202-3029 PERMIT/SERVICES <br /> SUBJECT: Kleinfelder Report, Dated: January 3,2008 <br /> Underground Storage Tank Assessment at Granite Construction Company <br /> 10500 South Harlan Road <br /> French Camp, California <br /> Dear Mr. Knoll, <br /> Granite Construction Company is respectfully requesting a"No Further Action" letter from the <br /> San Joaquin County Environmental Health Department regarding the closure-in-place of five(5) <br /> underground tanks. In the attached tank assessment report prepared by Kleinfelder,soil samples <br /> collected underneath the five tanks did not detect any reportable concentrations of petroleum <br /> hydrocarbon constituents. In addition, accessibility to the underground tanks is constrained, <br /> because located directly above are two(2) 30,000-gallon bituminous asphalt tanks that currently <br /> support asphalt making operations. Due to limited access,the option of removing the five <br /> underground tanks would create a negative affect to the business operations at this site. <br /> Therefore, Granite concurs with Kleinfelder's recommendation to perform the following <br /> abandonment methodology: <br /> 1. Abandon-in-Place, five (5)underground tanks. <br /> 2. Pour and fill a concrete & sand slurry into all five underground tanks. <br /> 3. The anticipated completion date of this project is Monday, March 31, 2008. <br /> Please contact me at(209) 234-3529 with any questions or comments. <br /> Sincerely, <br /> fria'n Hof an <br /> Environmental Coordinator <br /> Cc: Syd DeVries, Plants Manager <br /> Hop Essick, Branch Manager <br /> Doug Heard, Kleinfelder <br /> Stockton Branch <br /> Box 151 <br /> Stockton,CA 95201 <br /> (209)982-4750 <br /> FAX(209)983-1257 <br />
