## Abstract

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (``CERCLA'' or ``the Act''), as amended, requires that the National Oil and Hazardous Substances Pollution Contingency Plan (``NCP'') include a list of national priorities among the known releases or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States. The National Priorities List (``NPL'') constitutes this list. The NPL is intended primarily to guide the Environmental Protection Agency (``EPA'' or ``the Agency'') in determining which sites warrant further investigation to assess the nature and extent of public health and environmental risks associated with the site and to determine what CERCLA-financed remedial action(s), if any, may be appropriate. This rule adds 10 new sites to the NPL: 9 sites to the General Superfund Section of the NPL and one site to the Federal Facilities Section of the NPL.
