National Oil and Hazardous Substance Pollution Contingency Plan National Priorities List Update

The United States Environmental Protection Agency (EPA) Region 6 is publishing a direct final notice for partial deletion of the RSR Corporation Superfund Site (RSR Site), Operable Unit (OU) No. 4 and Subarea 1 of Operable Unit (OU) No. 5, located in Dallas, Dallas County, Texas, from the National Priorities List (NPL). This partial deletion does not include OU No. 1, OU No. 2, OU No. 3 or Subareas 2, 3, and 4 of OU NO. 5. The partial deletion for OU No. 4 and Subarea 1 of OU No. 5 came at the request of a developer to help facilitate the purchase of these properties. The EPA plans to delete the other operable units and areas of the RSR Superfund Site in 2008. The NPL, promulgated pursuant to Section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is appendix B of 40 CFR Part 300, which is the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This direct final notice for partial deletion is being published by the EPA with the concurrence of the State of Texas, through the Texas Commission on Environmental Quality (TCEQ), because the EPA has determined that all appropriate response actions under CERCLA have been completed and, therefore, further remedial action pursuant to CERCLA is not appropriate for OU No. 4 and Subarea 1 of OU No. 5.
