{"abstract":"The Environmental Protection Agency (EPA) is issuing a Notice of Intent to delete one site, Corozal Well, from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to 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). 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. However, this deletion does not preclude future actions under Superfund.","action":"Proposed rule; notice of intent.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2025/09/11/2025-17505.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"300","title":40}],"citation":"90 FR 43988","comment_url":null,"comments_close_on":"2025-10-14","correction_of":null,"corrections":[],"dates":"Comments regarding this proposed action must be submitted on or before October 14, 2025.","disposition_notes":null,"docket_ids":["EPA-HQ-OLEM-2025-1247","FRL-12905-01-OLEM"],"dockets":[{"supporting_documents":[{"title":"Responsiveness Summary for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0011"},{"title":"Deletion Docket Index for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0004"},{"title":"Puerto Rico Department of Natural and Environmental Resources Concurrence on the National Priority List Delisting for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0003"},{"title":"Final Close-Out Report for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0002"}],"agency_name":"EPA","documents":[{"comment_count":7,"comment_start_date":"2025-09-11","updated_at":"2025-10-15T00:01:26.834-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-HQ-OLEM-2025-1247-0001","allow_late_comments":false,"id":"EPA-HQ-OLEM-2025-1247-0001","comment_end_date":"2025-10-15","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":4,"id":"EPA-HQ-OLEM-2025-1247","title":"The National Priorities List (NPL) Deletion Docket for Corozal Well (Full Deletion)"}],"document_number":"2025-17505","effective_on":null,"end_page":43990,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/09/11/2025-17505.xml","html_url":"https://www.federalregister.gov/documents/2025/09/11/2025-17505/proposed-deletion-from-the-national-priorities-list","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-17505?publication_date=2025-09-11","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-09-11/2025-17505/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":332,"last_updated":"2026-06-25 14:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-09-11/pdf/2025-17505.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-17505.pdf?1757508315","publication_date":"2025-09-11","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/09/11/2025-17505.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Responsiveness Summary for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0011"},{"title":"Deletion Docket Index for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0004"},{"title":"Puerto Rico Department of Natural and Environmental Resources Concurrence on the National Priority List Delisting for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0003"},{"title":"Final Close-Out Report for the Corozal Well Site","document_id":"EPA-HQ-OLEM-2025-1247-0002"}],"comments_count":7,"agency_id":"EPA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-HQ-OLEM-2025-1247","supporting_documents_count":4,"docket_id":"EPA-HQ-OLEM-2025-1247","document_id":"EPA-HQ-OLEM-2025-1247-0001","regulation_id_number":null,"title":"The National Priorities List (NPL) Deletion Docket for Corozal Well (Full Deletion)","checked_regulationsdotgov_at":"2025-10-15T04:01:26Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":43988,"subtype":null,"title":"Proposed Deletion From the National Priorities List","toc_doc":"Proposed Deletion from the National Priorities List","toc_subject":null,"topics":["Air pollution control","Chemicals","Environmental protection","Hazardous substances","Hazardous waste","Intergovernmental relations","Natural resources","Oil pollution","Penalties","Reporting and recordkeeping requirements","Superfund","Water pollution control","Water supply"],"type":"Proposed Rule","volume":90}
