The mineral processing and mining sectors generate more wastes that are corrosive or contain toxic metals than any other industrial sector. Over the past decade, EPA has found that many of the facilities that manage these wastes have contaminated groundwater, surface water and soil either through failure to comply with state or federal environmental requirements or legally permissible waste management practices. Largescale mineral processing and mining operations often severely affect water supplies and wildlife and create environmental damage. Many facilities are located in populated areas, making health risks a significant concern for EPA. EPA has listed over 80 mineral processing and mining sites on the Superfund National Priorities List (NPL) and, along with states, undertaken expensive cleanups using a variety of legal authorities. A detailed description of mining and mineral processing activities and the resulting environmental damages can be found at www.epa.gov/superfund/programs/aml/index.htm and www.epa.gov/epaoswer/other/mining/minedock/damage/damage.pdf. The facilities that EPA plans to investigate have the potential to cause the environmental problems described in these documents.
