STATE OF CALIFORNIA ` GEORGE DEUKMEJIAN,Governor <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD— <br /> CENTRAL VALLEY REGION :dam <br /> 3443 ROUTIER ROAD <br /> SACRAMENTO,CA 95827-3098 <br /> t. r <br /> 5 November 1987 <br /> Mr. Al Olson <br /> San Joaquin Local Health District <br /> Environmental Health Department <br /> Post Office Box 2009 <br /> Stockton, CA 95201 <br /> CAMPBELL CHAIN FACILITY CONTAMINATED SOIL DISPOSAL AT FORWARD LANDFILL, <br /> SAN JOAQUIN COUNTY (CASE #2209) <br /> At your request, Beta Associates sent me a report describing soil contamination <br /> at the Campbell Chain Facility in- Union City. In that report, Beta proposes to <br /> dispose of 300 cubic yards of soil contaminated with metals at Forward Landfill . <br /> The concentration of metals is such that the soil will have to be treated <br /> specially if it is to be sent to Forward. The soil will have to be placed in a <br /> nonacidic environment, meaning that co-disposal with municipal refuse is <br /> prohibited. The soil may be used in the foundation layer of the final cover <br /> that will be installed over Waste Management Unit (WMU) A. with Department of <br /> Health Services approval . From the time the soil is transported to Forward <br /> until it is incorporated into the foundation layer of the cap, it should be <br /> covered with plastic tarps and plainly marked. This will prevent problems with <br /> runoff and ensure that the soil is not confused with other on-site soil piles <br /> that, after aeration to decrease levels of petroleum hydrocarbons, are used for <br /> daily cover in WMU D. <br /> If you have any questions, contact me at (916) 361-5737. <br /> 6; fi, 6v'o, <br /> TIMOTHY A.
