{"abstract":"The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (\"CERCLA\" or \"the Act\"), as amended, requires that the National Oil and Hazardous Substances Pollution Contingency Plan (\"NCP\") include a list of national priorities among the known releases or threatened releases of hazardous substances, pollutants or contaminants throughout the United States. The National Priorities List (\"NPL\") constitutes this list. The NPL is intended primarily to guide the Environmental Protection Agency (\"the EPA\" or \"the agency\") in determining which sites warrant further investigation. These further investigations will allow the EPA to assess the nature and extent of public health and environmental risks associated with the site and to determine what CERCLA-authorized remedial action(s), if any, may be appropriate. This rule adds one site, Gelman Sciences Inc., to the General Superfund section of the NPL.","action":"Final rule.","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/2026/03/13/2026-04904.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"300","title":40}],"citation":"91 FR 12304","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The rule is effective on April 13, 2026.","disposition_notes":null,"docket_ids":["EPA-HQ-OLEM-2024-0067","FRL-11724.1-02-OLEM"],"dockets":[{"supporting_documents":[{"title":"Support Document for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0161"},{"title":"Revised HRS Documentation Record - Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0160"},{"title":"NPL Site Narrative for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0159"},{"title":"State/Tribal Correspondence for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0004"},{"title":"HRS Documentation Record for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0003"},{"title":"NPL Site Narrative for Gelman Sciences Inc","document_id":"EPA-HQ-OLEM-2024-0067-0002"}],"agency_name":"EPA","documents":[{"comment_count":null,"comment_start_date":null,"updated_at":"2026-03-13T10:58:21.562-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-HQ-OLEM-2024-0067-0158","allow_late_comments":false,"id":"EPA-HQ-OLEM-2024-0067-0158","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":6,"id":"EPA-HQ-OLEM-2024-0067","title":"National Priorities List (NPL) for Gelman Sciences Inc., Ann Arbor, MI"}],"document_number":"2026-04904","effective_on":"2026-04-13","end_page":12308,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/03/13/2026-04904.xml","html_url":"https://www.federalregister.gov/documents/2026/03/13/2026-04904/national-priorities-list","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-04904?publication_date=2026-03-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-03-13/2026-04904/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":727,"last_updated":"2026-07-26 06:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-03-13/pdf/2026-04904.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-04904.pdf?1773319508","publication_date":"2026-03-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/03/13/2026-04904.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Support Document for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0161"},{"title":"Revised HRS Documentation Record - Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0160"},{"title":"NPL Site Narrative for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0159"},{"title":"State/Tribal Correspondence for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0004"},{"title":"HRS Documentation Record for Gelman Sciences Inc.","document_id":"EPA-HQ-OLEM-2024-0067-0003"},{"title":"NPL Site Narrative for Gelman Sciences Inc","document_id":"EPA-HQ-OLEM-2024-0067-0002"}],"comments_count":0,"agency_id":"EPA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-HQ-OLEM-2024-0067","supporting_documents_count":6,"docket_id":"EPA-HQ-OLEM-2024-0067","document_id":"EPA-HQ-OLEM-2024-0067-0158","regulation_id_number":null,"title":"National Priorities List (NPL) for Gelman Sciences Inc., Ann Arbor, MI","checked_regulationsdotgov_at":"2026-03-14T17:55:03Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":12304,"subtype":null,"title":"National Priorities List","toc_doc":"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":"Rule","volume":91}
