EPA SELECTS CLEANUP REMEDY FOR THE KOPPERS, INC. SUPERFUND SITE IN MORRISVILLE, N.C.
ATLANTA, Dec. 24 /PRNewswire/ -- The U.S. Environmental Protection Agency announced today that a Record of Decision (ROD) has been signed for the Koppers, Inc. Superfund site in Morrisville, N.C. The ROD outlines the remedy that will be used to address the soil, surface water and groundwater contamination at the site. Cleanup costs are estimated at $11 million. The cleanup design will include treatability studies to establish the effectiveness of dechlorination as the remedy for the contaminated soils. If this process does not adequately reduce contaminant levels, the soil will be excavated and transported to a permitted facility for incineration. The contaminated groundwater and surface water will be treated by carbon adsorption. Cleanup of the soil is expected to take up to two years, or longer, if dechlorination is utilized; however, if the soil is incinerated, cleanup is estimated at six to twelve months. Groundwater treatment is expected to take up to 30 years and surface water treatment is expected to take approximately three months. The ROD and the Administrative Record, a compilation of documents which formed the basis for EPA's selection of the remedy, are available for public review at the Cary Branch of the Wake County Library in Cary, N.C. The Koppers, Inc. site is located on Highway 54, one mile north of Morrisville. The site was added to EPA's National Priorities List (NPL) of hazardous waste sites on March 31, 1989. -0- 12/24/92 /CONTACT: Barbara Benoy, project manager, 404-347-7791, or Diane Barrett, Community Relations, 404-347-7791, or Carl Terry, press office, 404-347-3004, all of the U.S.Environmental Protection Agency/
