EPA seal(Lenexa, Kan., Jan. 2, 2018) - As a result of staff working hard to implement Administrator Pruitt’s initiatives to make strides in cleaning up the nation’s most contaminated toxic land sites, the U.S. Environmental Protection Agency (EPA) is announcing significant improvement in 2017 – through the deletion of all or parts of seven Superfund sites from the National Priorities List (NPL), including the Ellisville Superfund Site in St. Louis County, Mo. This is more than triple the number of sites removed from the list in 2016. 

“We have made it a priority to get these sites cleaned up faster and in the right way,” said EPA Administrator Scott Pruitt. “By creating a streamlined task force and making major remedy decisions that hold potentially responsible parties accountable for cleanup, the Superfund program is carrying out the Agency’s mission of protecting human health and the environment more every day.”

The Ellisville Superfund Site is located in west St. Louis County, about 20 miles west of downtown St. Louis. The site includes three nearby detached subsites: Bliss-Ellisville, the Callahan property, and the Rosalie property.

During the 1960s and 1970s, the Bliss Waste Oil Company transported and disposed of waste oil products, industrial wastes, and chemical wastes. The company disposed of these wastes in pits and drums, as well as on the ground at the 11-acre Bliss property, the eight-acre Callahan property, and the 85-acre Rosalie property.

In July 2017, EPA announced the deletion of the Callahan property subsite from the NPL. EPA oversaw the removal of contaminated soil down to bedrock at the Callahan property, and it now meets the criteria for unlimited use.

In 2016, EPA had deletion activities at two NPL sites, one full site, and portions of another. But in 2017, under the leadership of Administrator Pruitt, EPA has deleted three entire sites and portions of four others. This increase in deletions reflects the Administrator’s commitment to accelerating progress, reducing risks at Superfund sites, and returning sites to productive use.

These deletions come on the heels of Administrator Pruitt’s list of 21 sites that have been targeted for immediate and intense attention – a direct response to the Superfund Task Force Recommendations issued this summer.

NPL deletion occurs when all the remedies are successfully implemented and no further cleanup is required to protect human health or the environment. The Agency deletes portions of NPL sites when work at those portions is complete and other parts of the site still have ongoing actions.

The three completely deleted sites are:

  • Nutting Truck & Caster Co. in Minnesota, originally contaminated with trichloroethylene (TCE) in groundwater
  • Shpack Landfill in Massachusetts, which had contaminated soil, sediment and groundwater
  • Perdido Ground Water Contamination in Alabama, which was originally contaminated with benzene

EPA completed partial deletions for:

  • Mystery Bridge Road/U.S. Highway 20 in Wyoming, which had a groundwater plume and soils that contained benzene, toluene, ethylbenzene, and total xylenes
  • Ellisville Site in Missouri, which contained drums full of hazardous materials
  • Omaha Lead in Nebraska, where surface soil was contaminated by deposition of air emissions from historic lead smelting and refining operations
  • North Penn - Area 6 in Pennsylvania, where soils and groundwater were contaminated with volatile organic compounds

Deleting a site or portions of a site from the NPL may facilitate future redevelopment, one of EPA’s goals for the Superfund program.

The NPL is one focus area of the Superfund Task Force Recommendations to improve and revitalize the Superfund program. Work to prioritize and reinvigorate the Superfund program is underway and will continue into 2018.
