The 3.5-acre National Electric Coil Co./Cooper Industries site is located in Dayhoit, Kentucky. It includes the area where National Electric Coil Company operated a coal mining machinery repair facility from 1951 to 1987. From 1987 to 2010, another company operated a similar facility at the site. In 2010, automobile storage operations began at the site. The U.S Environmental Protection Agency placed the site on the Superfund program’s National Priorities List (NPL) in 1992 because of contaminated air, soil and groundwater resulting from coal mining machinery repair operations.

EPA, the Kentucky Department for Environmental Protection (KDEP) and the site’s potentially responsible parties (PRPs) have investigated conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Contamination does not currently threaten people living and working near the site. Since 1989, a water line has connected residences and businesses nearby to the public water supply. By treating and monitoring groundwater and conducting required Five-Year Reviews, EPA, KDEP and the site’s PRPs continue to protect people and the environment from site contamination.

What Has Been Done to Clean Up the Site?

The 3.5-acre site is located on Old Highway 119 next to the Cumberland River in Dayhoit, Harlan County, Kentucky. The site includes a main manufacturing building, two smaller buildings, an asphalt paved parking lot and a grass-covered riverbank area. A mobile home park borders the site to the south, a Kentucky Utility Company electrical substation borders the site to the north, Old Highway 119 borders the site to the west and the Cumberland River borders the site to the east. The residential communities bordering the site and south of the site are low-income areas.

  • From 1951 to 1987, National Electric Coil Company operated a coal mining machinery repair facility under the ownership of the McGraw Edison Company. Operations included rewinding electric motors and manufacturing coils as well as rebuilding machinery used in the coal mining industry. Operations used chemicals to remove oil and tar from the used motors, capacitors, transformers and other equipment prior to rebuilding the equipment and discharged chemicals, wastes and contaminated transformer oils onto the ground and through a drainage pipe to the Cumberland River. Cooper Industries purchased the McGraw Edison Company in 1985 and continued the facility’s operations until 1987, when Treen Land Company bought the site property.
  • In 1992, the EPA listed the site on the NPL. Charles Dozier owned the site from 1994 until 2010 and the coal mining machinery repair facility operated under the National Electric Services Management Group. Currently, Jennifer Pennington owns the site and Pennington’s Wrecker Service operates on site. Operations include storage of wrecked automobiles on the asphalt parking lot next to the main building, storage of auto parts in on-site buildings and sale of salvage auto parts. Land use at the site is not expected to change in the near future.
  • McGraw-Edison/Cooper, Treen Land Company and National Electric Coil Company, the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by EPA and KDEP. The PRPs began preliminary groundwater pump-and-treat activities in 1993 to minimize migration of contamination. A water line was put in place to connect residences and businesses to the public water supply.
  • Between 1990 and 1991, the site’s PRPs conducted interim cleanup activities, which included digging up and disposing of contaminated source soils off site. Groundwater cleanup activities were c in 1998
  • EPA completed the site’s third Five-Year Review in 2013. It found that the site’s groundwater cleanup remains protective of human health and the environment in the short term. Continued protectiveness of the remedy requires further groundwater studies. EPA plans to complete the next Five-Year Review in 2018.

What Is the Current Site Status?

In 1996, EPA issued the site’s long-term cleanup plan. It included recovering contaminated groundwater from beneath the site and properties next to the site; using an air stripper to treat contaminated groundwater; treating contaminated gas from the air stripping operations; and discharging treated groundwater to the Cumberland River. In 2011, EPA revised the cleanup plan to include institutional controls to limit groundwater use and remove the treatment of gas from the air stripper.

The ground water pump-and-treat system continues to operate at the site. The site’s PRPs continue to conduct semi-annual ground water monitoring. EPA completed the last Five-Year Review in 2013 and the next Five-Year review is due in fall 2018.

Sampling and Monitoring

Semi-annual ground water monitoring is performed by the PRP’s contractors and documented in Semi-annual ground water monitoring reports.

Enforcement Information

EPA negotiated legal agreements with the site’s PRPs to investigate and clean up the site. McGraw-Edison/Cooper continues to fund site cleanup, monitoring and oversight activities.
