Site Description

The South Point Plant site, located in Lawrence County, Ohio, is a 610-acre industrial area where numerous potentially responsible parties (PRPs), including Allied-Signal, Ashland Oil, and South Point Ethanol (SPE), produced ammonia fertilizer and formaldehyde and operated a coal-water fuel pilot plant, a pitch prilling test plant, and an ethanol production plant. The site contains three unlined landfills that contain a variety of wastes including fly ash, plant refuse, coal cinders, and small quantities of chemicals. In addition, numerous activities have contributed to the contamination of groundwater and soils, including a number of major spills at the site.

The site is located on the eastern flood plain of the Ohio River. Approximately 65,000 people live within three miles of the site. The village of South Point is the nearest town. The intake for the Ashland, Kentucky municipal water supply, which serves approximately 24,000 people, is located on the Ohio River about one mile downstream of the site. The village of South Point draws its water supply from a well field near the site that supplies drinking water to an estimated 4,000 people.

Site Responsibility

This site is being addressed through federal, state, and potentially responsible party (PRP) actions.

Threats and Contaminants

The groundwater is predominantly contaminated with chloride, nitrate, and sulfate, with lesser amounts of the heavy metals iron and manganese. Soils are predominantly contaminated with heavy metals, including arsenic, and lesser amounts of chloride, nitrate, ammonium, and sulfate. Potential health threats exist from accidental ingestion and direct contact with soils and groundwater.

Cleanup Progress

The PRPs, who are past owners, operators, and generators, voluntarily entered into an Administrative Order on Consent (AOC) with the United States Environmental Protection Agency (EPA) to perform a Remedial Investigation/Feasibility Study (RI/FS). The AOC was signed by EPA on April 21, 1987. The PRPs submitted a Final RI Report, including a risk assessment, that confirmed the presence of volatile organic compounds (VOCs), semi-VOCs, and metals in soils and groundwater.

Due to the potential for the municipal wells to be affected by contamination from the site, one of  the PRPs entered into  an agreement, dated November 1983, with the village of South Point.  Under this agreement, the PRP would continue to pump some on-site process wells in order to hydraulically contain any contaminated groundwater on-site.  Even though that PRP went out of business, the other PRPs continue to honor the agreement.  This containment system will continue to operate at a rate of 2 to 4 million gallons per day until the contaminants in groundwater have dropped to acceptable health-based levels.  

A final version of the FS was approved in June 1997.  A Record of Decision, which selected a final remedy for the site, was signed in September 1997.  A Consent Decree was subsequently entered in federal court in November 1998 which required the PRPs to perform Remedial Design/Remedial Action (RD/RA) work.  RD work began in November 1998 and was completed in March 2001.  The RA work was completed in December 2001, and EPA conducted a final inspection on December 12, 2001.  A Preliminary Close Out Report, documenting the completion of construction at the site, was issued on December 28, 2001.  The final RA construction completion report was signed for the site on May 9, 2003.  In September 2011, EPA conditionally approved the Pump Well Modification Report and the proposed shutdown of pumping wells.  This conditional approval requires quarterly groundwater monitoring.  The groundwater flow map indicates that groundwater flow from the Site continues to be toward the Ohio River, and not toward the municipal well field. 

The EPA completed the first five-year review of the Site remedy in May 2006.   The second five-year review was completed in May 2011.  Both reviews found that the remedy was protective.  The next five-year review will be completed in 2016.  A Site-Wide Ready for Anticipated Use (SWRAU) determination was achieved for the Site on  September 22, 2011.  

Property Reuse

On July 26, 2002, EPA awarded the City of South Point a Superfund Redevelopment Initiative Program grant. This grant was used to promote redevelopment of the 610-acre site.
