Abstract:  The South Point PLT site is located in the Village of South Point, Ohio. The South Point Plant, which covers approximately 610 acres, is situated on a relatively flat portion of the Ohio River terrace within the eastern flood plain of the river. The Plant was constructed in 1943 by the federal government for the production of ammonium nitrate explosives. Starting in 1946, companies such as Allied Chemical, Ashland Oil, South Point Ethanol, and Air Liquid Corporation purchased the property, or portions of it, for their use. In addition, portions of the Plant property are leased for agricultural purposes. From 1943 to the mid-1980s, plant refuse, coal cinder, small quantities of laboratory chemicals, asbestos-insulation materials, waste lubrication oils, by-product and off-speculation solids (such as ammonium nitrate, urea, and melamine), and waste lubrication oils were disposed of in areas on site including the Eastern Disposal Area, Disposal Area D, Melamine Ponds, and Northern Fly Ash Ponds.In 1984, the Plant was added to the National Priorities List (NPL). Potentially Responsible Parties (PRPs) signed a consent order in the spring of 1987. Field activities associated with the site investigation were conducted from 1989 to 1992. The site investigation was completed in mid-1994 and the feasibility study was completed and approved by mid-1997.
Remedy:  The following outlines the major components of the selected remedy. In the active area: institutional controls, excavation in the mid-plant area and coke-oven gas blowdown areas, and on-site consolidation in Eastern Disposal Area/Mid-Plant Area. In the inactive area: institutional controls, containment including consolidation and placement of a single barrier cover for Disposal Area D, single barrier cover for Eastern Disposal Area, and surface controls for Northern Fly Ash Ponds; and for groundwater, institutional controls, containment using the existing pumping containment system, and discharge into the Ohio River. Also, some additional characterization will be required in the area of the former melamine ponds.
