The EPA on Monday, March 1, 2010, announced it is adding 10 new hazardous waste sites to the National Priorities List (NPL) of Superfund sites. An additional eight sites were proposed to be added sometime in the future.

The following 10 sites have been added to the National Priorities List:

• Salt Chuck Mine (Outer Ketchikan County, Alaska)
• JJ Seifert Machine (Ruskin, Fla.)
• Kerr-McGee Chemical Corp - Jacksonville (Jacksonville, Fla.)
• Chemetco (Madison County, Ill.)
• Lake Calumet Cluster (Chicago, Ill.)
• Gratiot County Golf Course (St. Louis, Mich.)
• Kerr-McGee Chemical Corp – Navassa (Navassa, N.C.)
• Gowanus Canal (Brooklyn, N.Y.)
• Black Butte Mine (Cottage Grove, Ore.)
• Van Der Horst USA Corporation (Terrell, Texas)

The following eight sites have been proposed to the National Priorities List:

• Sanford Dry Cleaners (Sanford, Fla.)
• St. Clair Shores Drain (St. Clair Shores, Mich.)
• Vienna Wells (Vienna, Mo.)
• ACM Smelter and Refinery (Cascade County, Mont.)
• Wright Chemical Corporation (Riegelwood, N.C.)
• Black River PCBs (Jefferson County, N.Y.)
• Dewey Loeffel Landfill (Nassau, N.Y.)
• Smokey Mountain Smelters (Knox County, Tenn.)

The contaminants found at the added sites included arsenic, benzene, chromium, copper, creosote, cyanide, dichloroethene (DCE), lead, mercury, perchloroethene, polychlorinated biphenyls (PCBs) and selenium, among others, according to an agency press release.

For the newly listed sites without viable potentially responsible parties, the EPA will investigate the full extent of the contamination before starting significant cleanup at the site. Therefore, it may be several years before significant cleanup funding is required for these sites.
