Conditions at proposal (June 24, 1988): The Caldwell Lace Leather Co., Inc., Site consists of three tannery waste areas in Logan County along the south side of Cemetery Road (State Highway 1039) approximately 2.5 miles northwest of Auburn, Kentucky. The areas have received wastes since 1972. Until 1985, the site was owned by Caldwell and received waste generated by leather-tanning processes at its plant in Auburn. In November 1985, North Park, Inc., a subsidiary of Auburn Leather Co., purchased the plant and disposal areas. The plant no longer conducts tanning operations.

During 1972-82, wastes, including chrome and vegetable tanning wash sludge, fleshings, screenings, and leather and gasket scraps, were buried in trenches or placed in unlined lagoons in a 5.5-acre area of the property. The sludge was generated from a chromium or vegetable tanning solution (water-soluble extracts from various plant parts) used to stabilize collagen fibers so that they are no longer biodegradable. Fleshings and screenings resulted from processes in which the leather is prepared for tanning by removing the hair and tissue from the flesh side of the skin.

The second disposal area is a 29.6-acre landfarm. In July 1982, the company received a conditional permit from the Kentucky Natural Resources and Environmental Protection Cabinet (KNREPC) to mix the sludges into the soil. The landfarm stopped operating in 1985.

In March 1983, KNREPC granted a conditional permit to Caldwell for the third area, a 5.1-acre landfill adjacent to the old trench/lagoon area, to accept only solid wastes, including the screenings, fleshings, leather scraps, and gasket scraps. In 1986, North Park, Inc., received a solid waste permit for the landfill from KNREPC. The company's operations generate only leather trimmings and scrap.

In July 1983, KNREPC detected chromium, including the most toxic hexavalent form, in a private well 1,200 feet from the landfill area. The well has been taken out of service. An estimated 660 people obtain drinking water from private wells within 3 miles of the site. Subsurface conditions are such that ground water migrates readily and contaminants can reach surface waters. The closest surface water intake is in Auburn, approximately 2 miles southeast of the site where Black Lick Creek originates.

KNREPC has documented violations of State waste management laws and regulations since 1978. In September 1984, Caldwell entered into an Agreed Order with the State to remedy past violations and prevent further violations. The closure consists of a three-phase approach involving application of lime and fertilizer, regrading and revegetation, and ground water/surface water monitoring.
