The Environmental Protection Agency (EPA) announces the deletion of one site, Corozal Well, from the Superfund National Priorities List (NPL). The NPL, created under 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). In accordance with 40 CFR 300.425(e), sites may be deleted from the NPL where no further response is appropriate. The EPA and the Commonwealth of Puerto Rico, through the Puerto Rico Department of Natural and Environmental Resources (PRDNER), have determined that all appropriate response actions under CERCLA have been completed and no further response is appropriate. However, this deletion does not preclude future actions under Superfund.
