The Superfund Program is responsible for assessing the impact of abandoned hazardous waste sites on or near tribal lands, resources, and populations. Since its inception in 1991, the Cherokee Nation Superfund Program has evaluated 117 potentially hazardous waste sites within the Cherokee Nation’s jurisdictional boundaries. These sites include solid waste dumps, landfills, and former industrial facilities. The Superfund Program also participates in the assessment of two sites–the former Tulsa Fuel and Manufacturing Company smelter site in Collinsville and Tar Creek–both sites are on the EPA’s National Priorities List. The program also provides technical training to environmental staff of the Cherokee Nation and other tribes.
