EPA ANNOUNCES DELETION OF FLORIDA SUPERFUND SITE FROM NATIONAL LIST OF HAZARDOUS WASTE SITES

 ATLANTA, Feb. 5 /PRNewswire/ -- The U.S. Environmental Protection Agency (EPA) announced today that the Pioneer Sand Company Superfund site is being deleted from the National Priorities List (NPL) of sites eligible for long-term cleanup under the Superfund law.
 Cleanup at the site, which is located five miles northwest of Pensacola in Escambia County, Fla., has been completed.
 EPA, in conjunction with the Florida Department of Environmental Regulation (FDER), has determined that all appropriate cleanup measures have been completed and no further action is required at the Pioneer Sand site. EPA has further determined that the cleanup is effective and fully protective of public health and the environment. EPA and the FDER conducted a final inspection of the cleanup in July 1991. Public comment on the deletion was solicited from Dec. 1, 1992 to Jan. 1, 1993.
 The Pioneer Sand Superfund site is an 11-acre inactive sand mining facility which was used to dispose of shredded auto parts, construction debris, and various industrial sludge and resins from the mid-1970s until 1981. Primary contaminants of concern at the site are volatile organic compounds, primarily toluene, ethylbenzene, xylene, and polynuclear aromatic hydrocarbons. EPA placed the site on the NPL in 1983. A study by FDER determined the extent of the contamination and evaluated appropriate cleanup technologies. In the summer of 1986, EPA removed materials contaminated with polychlorinated biphenyls (PCBs) found on the site.
 In 1986, EPA, with FDER's concurrence, selected a cleanup remedy which included landfill closure of fill and sludge pond areas, consisting of a protective cover to prevent further migration of contaminants, a leachate collection system, and a gas collection and venting system; on-site treatment and disposal of sludge and water in the sludge pond; and operation and maintenance activities for at least 20 years. Operation and maintenance will consist of maintenance of the landfill cap and systems, and monitoring of groundwater on and around the site. Pre-design sampling confirmed indications from earlier investigations that groundwater off-site was not contaminated.
 Reichhold Chemical Company, one of the parties responsible for sending hazardous materials to the site, agreed to design and implement the cleanup remedy under EPA and FDER direction. The U.S. Navy, another party that disposed of waste at the site, is sharing cleanup costs with Reichhold. The cleanup action included solidification and stabilization of 7550 cubic yards of sludge from the pond using Portland cement and sand to immobilize the contaminants and to support the protective cap placed over the area. In addition, an innovative treatment technology was used to immobilize a Light Non-Aqueous Phase Liquid (LNAPL or chemicals floating on top of groundwater) in the landfill. The LNAPL was discovered during the remedial design and was included in the cleanup. The cost of the cleanup was between $3 million and $4 million. The cost for future operation and maintenance is projected to be about $120,000 per year. Reichhold and the Navy will conduct operation and maintenance activities for 30 years.
 Sites deleted from the NPL remain eligible for federal cleanup or for enforcement action under the Superfund in the unlikely event that site conditions warrant any such actions in the future. Should such actions become necessary, the agency can still recover response costs on deleted sites.
