11 New Hazardous Waste Sites Proposed to the Superfund National Priorities List

EPA proposed 11 new hazardous waste sites to the Superfund National Priorities List (NPL) on March 8, 2004. The 11 sites proposed for listing include former mining sites, a former wood treater site, a manufacturing facility, and sites that have contaminated ground water, sediments, or residential soils. The sites contain a wide array of contaminants, including lead, arsenic, polychlorinated biphenyls (PCBs), volatile organic compounds, among others. EPA is not finalizing any sites in this notice.

The proposed sites were selected based on various factors including: risk to human health and the environment; the urgency of the need for response; projected total costs to the Fund; maintenance of a strong enforcement program; leverage of cleanups by others; and the level of support for listing from the state, tribes, and communities. The 11 proposed sites are:

  • Jacobsville Neighborhood Soil Contamination, Evansville, IN;
  • Devil's Swamp Lake, Scotlandville, LA;
  • Annapolis Lead Mine, Annapolis, MO;
  • Picayune Wood Treating, Picayune, MS;
  • Grants Chlorinated Solvents Plume, Grants, NM;
  • Diaz Chemical Corporation, Holley, NY;
  • Peninsula Boulevard Groundwater Plume, Hewlett, NY;
  • Ryeland Road Arsenic, Heidelberg Township, PA;
  • Cidra Ground Water Contamination, Cidra, Puerto Rico;
  • Pike Hill Copper Mine, Corinth, VT; and
  • Ravenswood PCE Ground Water Plume, Ravenswood, WV.

One of the sites is the Diaz Chemical Corporation (Diaz) site in Holley, New York, which is about 25 miles west of Rochester. Diaz had a long history of releases into the nearby residential community. Then, in January 2002, an air release left solidified drops of hazardous chemicals (2-chloro-6-fluorophenol and toluene) on homes and cars as far as 0.3 miles north of the site. Since EPA began response actions at the Diaz facility, the Agency assumed funding of temporary relocation of nearby residents who left their homes, is conducting an intensive investigation at the facility and in the nearby residential area, and plans to remove thousands of drums and other materials left behind at the site. EPA is proposing this site to the NPL due in part to this release, which lead to direct exposure to chemicals of nearby residents to the Diaz facility. In addition, on-site soils and groundwater are contaminated with volatile and semivolatile compounds. The subsurface contamination at the site potentially threatens public supply wells located 0.75 mile south.

The NPL serves primarily for informational purposes, identifying for the states and the public those sites that appear to warrant remedial actions. If these sites are eventually funded, EPA will work with states, tribes, local communities and other partners in identifying land reuse options and opportunities at these sites. Under its Land Revitalization Agenda announced last year, EPA made a commitment that revitalization and reuse will now be a formal part of planning at every site. Nationally, more than 70 percent of all Superfund sites are cleaned up by those responsible for the pollution. Since the beginning of the Superfund program, more than $21 billion in cleanup commitments and funding have been provided by the parties responsible for toxic waste sites.

With the 11 new sites proposed to the NPL, there are now 65 sites proposed and awaiting final agency action, including 59 non-federal sites and 6 federal facilities sites. There are 1,240 final sites on the NPL, including 1,082 non-federal sites and 158 federal facilities sites. Final and proposed sites now total 1,305. Cleanup construction has been completed at 892 sites and is underway at 360 additional sites.
