The 850-acre Fort Hartford Coal Co. Stone Quarry site is located 1.25 miles northwest of Olaton, Kentucky. It includes the area where Fort Hartford Coal Company operated a limestone mine and then a storage facility for salt cake fines from the late 1950s to 1991. EPA placed the site on the Superfund program�s National Priorities List (NPL) in 1990 because of contaminated air, groundwater and surface water resulting from storage operations.
EPA, the Kentucky Department for Environmental Protection (KDEP) and Commonwealth Aluminum Concast, Inc., the site�s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site. Site contamination does not currently threaten people living and working near the site. A water line connects residences and businesses to the public water supply. By treating groundwater, placing institutional controls on the site property and undertaking Five-Year Reviews, EPA, KDEP and the site�s PRP continue to protect human health and the environment from site contamination.
