National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List

The Environmental Protection Agency (EPA) announces the deletion of the Frontera Creek Superfund Site (Site) located in Rio Abajo within the Municipality of Humacao, Puerto Rico, from the National Priorities List (NPL). The NPL is Appendix B of 40 CFR Part 300 which is the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), which EPA promulgated pursuant to Section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended. EPA and the Puerto Rico Environmental Quality Board have determined that the Site poses no significant threat to public health or the environment and, therefore, no further response actions pursuant to CERCLA are appropriate.
