{"abstract":"PHMSA is proposing to revise the corrosion requirements in 49 CFR part 192 for gas distribution systems by replacing the 3-year reassessment interval with a 5-year reassessment interval following the replacement of pipeline segments or components in service lines. This change would provide cost savings to gas distribution operators.","action":"Notice of proposed rulemaking (NPRM).","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Pipeline and Hazardous Materials Safety Administration","name":"Pipeline and Hazardous Materials Safety Administration","id":408,"url":"https://www.federalregister.gov/agencies/pipeline-and-hazardous-materials-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/408","parent_id":492,"slug":"pipeline-and-hazardous-materials-safety-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2025/07/01/2025-12117.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"192","title":49}],"citation":"90 FR 28603","comment_url":null,"comments_close_on":"2025-09-02","correction_of":null,"corrections":[],"dates":"Persons interested in submitting written comments on this proposed rule must do so by September 2, 2025.","disposition_notes":null,"docket_ids":["Docket No. PHMSA-2025-0115"],"dockets":[{"supporting_documents":[{"title":"PRIA-Atmospheric Corrosion Reassessment","document_id":"PHMSA-2025-0115-0003"}],"agency_name":"PHMSA","documents":[{"comment_count":6,"comment_start_date":"2025-07-01","updated_at":"2026-09-08T08:55:59.538-04:00","comment_url":"https://www.regulations.gov/commenton/PHMSA-2025-0115-0001","allow_late_comments":false,"id":"PHMSA-2025-0115-0001","comment_end_date":"2026-09-05","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"PHMSA-2025-0115","title":"Pipeline Safety: Atmospheric Corrosion Reassessment for Pipeline Replacements"}],"document_number":"2025-12117","effective_on":null,"end_page":28606,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/07/01/2025-12117.xml","html_url":"https://www.federalregister.gov/documents/2025/07/01/2025-12117/pipeline-safety-atmospheric-corrosion-reassessment-for-pipeline-replacements","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-12117?publication_date=2025-07-01","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-07-01/2025-12117/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":687,"last_updated":"2026-11-07 16:15:04 -0500"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-07-01/pdf/2025-12117.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-12117.pdf?1751055317","publication_date":"2025-07-01","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/07/01/2025-12117.txt","regulation_id_number_info":{"2137-AF85":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2137-AF85/pipeline-safety-atmospheric-corrosion-reassessment-for-pipeline-replacements","title":"Pipeline Safety: Atmospheric Corrosion Reassessment for Pipeline Replacements","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2137-AF85&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2137-AF85"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"PRIA-Atmospheric Corrosion Reassessment","document_id":"PHMSA-2025-0115-0003"}],"comments_count":6,"agency_id":"PHMSA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=PHMSA-2025-0115","supporting_documents_count":1,"docket_id":"PHMSA-2025-0115","document_id":"PHMSA-2025-0115-0001","regulation_id_number":null,"title":"Pipeline Safety: Atmospheric Corrosion Reassessment for Pipeline Replacements","checked_regulationsdotgov_at":"2026-09-09T15:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":28603,"subtype":null,"title":"Pipeline Safety: Atmospheric Corrosion Reassessment for Pipeline Replacements","toc_doc":"Atmospheric Corrosion Reassessment for Pipeline Replacements","toc_subject":"Pipeline Safety","topics":["Natural gas","Pipeline safety","Pipelines"],"type":"Proposed Rule","volume":90}
