National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the El Toro Marine Corps Air Station Superfund Site

The Environmental Protection Agency (EPA) Region IX is publishing a direct final Notice of Deletion of portions of the El Toro Marine Corp Air Station Superfund Site (Site), located in Irvine, California, from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This direct final partial deletion is being published by EPA with the concurrence of the State of California through the Department of Toxic Substances Control (DTSC), because EPA has determined that all appropriate response actions at these identified parcels under CERCLA have been completed. However, this partial deletion does not preclude future actions under Superfund. This partial deletion pertains to all Site media, including soil and groundwater, of parcels I-A, II-A, III-A, II-J, II-Q, II-S, II-T, III-C, I-C, II-U, I-B, I-E, I-G, I-H, I-I, I-J, I-L, I-M, I-P, II-G, II-I, II-P, III-D, I-K, I-N, I-O, I-S, II-E, II-L, II-M, II-R, I-Q, I- R, II-B, II-K, and II-O of the Site. The current remaining areas of the Site will remain on the NPL and are not being considered for deletion as part of this action.
