 EPA ANNOUNCES MEETING AND COMMENT PERIOD ON PROPOSED CLEANUP
 AT CIBA GEIGY SUPERFUND SITE IN MCINTOSH, ALA.
 ATLANTA, May 13 /PRNewswire/ -- The United States Environmental Protection Agency (EPA) announced today the availability of a proposed plan for addressing contamination in one disposal area at the Ciba Geigy Superfund site in Washington County, Ala.
 Prior to selecting a cleanup remedy for this area, referred to as waste management area number 8, EPA will consider comments from the public and provide responses to those comments. The comment period began on April 30 and continues through May 29.
 EPA will hold a public meeting on Tuesday, May 19 at the McIntosh Town Hall on Commerce Street (U.S. Highway 43 North) in McIntosh beginning at 6:30 p.m. All interested citizens are invited to review the plan and the administrative record at the McIntosh Town Hall and to attend the meeting.
 EPA selected a remedy to address contamination in 10 of 11 former disposal areas on the site in 1991, and Ciba Geigy has already implemented a groundwater treatment remedy at the site. Waste management area number 8 was not included in the remedy selected in 1991 because the area contains mixed waste, and EPA needed additional information on the area before proposing a remedy. EPA considered the following alternatives for addressing contamination at waste management area number 8:
 1) No action -- used as comparison for other alternatives at no cost.
 2) Containment -- slurry wall to prevent movement of contamination at a cost of $10.9 million.
 3) Stabilization/Solidification -- excavation of contaminated materials for mixing with cement and placement in an on-site landvault at a cost of $30.4 million.
 4) Thermal Treatment -- excavation of highly contaminated materials for on-site incineration and disposal of ash in on-site landvault or use of innovative technology (if proven effective) and stabilization/solidification of moderate contamination or use of innovative technology if effective at a cost of $49.7 million.
 EPA will seek concurrence from the Alabama Department of Environmental Management (ADEM) prior to selecting a final remedy. EPA currently prefers alternative 4 above. EPA believes this remedy would most effectively reduce the threat posed to groundwater by contamination in this disposal area at the site.
 The site, placed on the Superfund National Priorities List of hazardous waste sites in 1983, is located about 50 miles north of Mobile. The McIntosh facility began operations in 1952 with the production of DDT. Today, the plant manufactures a variety of chemical products. The facility covers about 1,500 acres and employs about 1,300 workers. The site is located on the Tombigbee River; and under EPA direction, Ciba Geigy is currently beginning a study of the impact of site contamination on the floodplain. The site is contaminated by a variety of chemicals including pesticides, heavy metals and volatile organic compounds.
 Written comments must be postmarked by the end of the comment period and submitted to Betty Winter, Community Relations Coordinator, South Superfund Remedial Branch, U.S. EPA - Region IV, 345 Courtland St. N.E., Atlanta, GA 30365
