Final Record of Decision/Remedial Action Plan for Installation Restoration Site 12, Boat Channel Sediments

The project will involve dredging 9.10 acres of contaminated marine sediments from the northern portion of the San Diego Bay Boat Channel to prevent a release of hazardous substances in the sediment, including: copper, lead, zinc, total chlordane, and total dichlorodiphenyltrichloroethane. Dredging will be to a depth of one to two feet. The project is expected to generate approx 23,200 cy of dredged contaminated marine sediment. The project would also include dewatering dredged material on a barge, testing dredged materials, vessel transport of dredged material to Naval Base San Diego, and truck transport of dredged materials to the Copper Mountain Landfill disposal facility in Welton, Arizona.
