1800 PITTSBURGH AVENUE
The site is located at 1800 Pittsburgh Avenue on a section of the Charleston Peninsula formed by the confluence of the Ashley and Cooper Rivers in Charleston, South Carolina. A tidal creek and marsh along Shipyard Creek border the site to the north and east, industrial and commercial land uses border the site to the south, and a CSX rail line borders the site to the west. Union Heights, a neighborhood with low-income and minority residents, is located just west of the site, past a CSX rail line. The Koppers Co., Inc. (Charleston Plant) Superfund site is located approximately one half-mile south of the site. From 1941 until 1998, a ferrochromium alloy smelting plant operated at the site. Plant operations included separating metal content from its ore using furnaces. Pittsburgh Metallurgical Company operated the plant from 1941 to 1966; Airco (British Oxygen Corporation) operated the plant from 1966 to 1979; and Macalloy Corporation operated the plant from 1979 to 1998. The Department of Defense has owned, operated or used areas of the site to produce and store ferrochromium alloy, chrome ore and slag since 1942. Operations at the site also collected an estimated 80,000 tons of air pollution control material, consisting of collected particulate dust and sludge, in an unlined surface reservoir on site. The plant discharged process water off site to the Shipyard Creek and a wetlands area. In 2000, EPA listed the site on the NPL. In 2005, Ashley II of Charleston, LLC purchased the site and developed approximately 30 acres on the southern portion of the site into an industrial park. Approximately 110 acres on the northern portion of the site remains undeveloped and covered with trees and shrubs. The site’s cleanup can support industrial land uses.
