The Hegeler Zinc facility in Danville, Ill., and Copley Square Plaza of Copley, Ohio are two of the sites added to the list. The Hegeler site is a 100-acre former zinc smelter which operated from 1906 until about 1954. The property includes a 5-acre lead-contaminated slag waste pile. Studies confirm lead and cadmium contamination. The site is secured from public access and work is scheduled to begin this fall.

The Copley site is a former Danton Dry Cleaners that operated from 1963 to 1994. The site is 3 acres in size. Ohio EPA studies confirmed the presence of tetrachloroethylene, commonly known as PCE, in the groundwater. The EPA has selected a contractor to review the data collected and determine what other information should be collected to begin the cleanup.

About 70 percent of the sites listed on the NPL have been paid for or performed by parties that were held responsible. The just-added sites bring the total to 1,245 final NPL sites, with 64 proposed sites awaiting final agency action. Cleanup construction has been completed at 932 sites.
