Case Description

The Halaco site (Site) is located in coastal Ventura County at 6200 Perkins Road, Oxnard, CA 93033. Halaco Engineering Company operated a secondary metal smelter at the site from 1965 to 2004, recovering aluminum, magnesium, and zinc from dross, castings, cans, car parts, and other scrap metal. The Site includes an 11-acre area containing the former smelter, and an adjacent 26-acre waste management area where wastes were deposited. Immediately adjacent to the Site is a portion of the Ormond Beach wetlands, which are one of the few remaining wetlands in the area and home to several endangered or threatened species.

During its 40 years of operation, Halaco produced a large quantity of waste (i.e., slag) containing residual metals from the smelting process. From about 1965 to 1970, Halaco discharged waste into unlined settling ponds in or adjacent to the Oxnard Industrial Drain. From about 1970 to 2002, Halaco deposited wastes into unlined earthen settling ponds east of the smelter. More than 700,000 cubic yards of waste remain on-site.

Most waste remains on-site, including more than 700,000 cubic yards in the waste management area and 50,000 cubic yards buried in the 11-acre area where the smelter operated. Elevated levels of aluminum, barium, beryllium, cadmium, chromium, copper, lead, magnesium, manganese, nickel, and zinc are present in the wastes and in affected soils and sediments. Some areas also contain elevated levels of thorium and radium. Waste material has moved into both underlying groundwater and sediments in the Oxnard Industrial Drain.

The Site was added by the EPA in September 2007 To the Superfund National Priorities List (NPL).
