{"abstract":"The Federal Hazardous Materials Transportation Act (HMTA), 49 U.S.C. 5101 et seq., preempts California's reusability mandate for propane cylinders in California Public Resources Code, Sections 42395- 42395.2. The reusability mandate imposes localized design and manufacturing requirements on a container that is represented, marked, certified, or sold as qualified for use in the transportation of a hazardous material--specifically, propane--that are not substantively the same as the requirements in the HMR. The reusability mandate is also an obstacle to accomplishing and carrying out the HMTA. By banning a federally authorized, safety-compliant packaging based on localized waste management preferences, California creates a fragmented regulatory patchwork that undermines the primacy and uniformity of the Federal transportation safety framework.","action":"Notice of administrative determination of preemption.","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/2026/09/10/2026-18501.html","cfr_references":[],"citation":"91 FR 57684","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":null,"disposition_notes":null,"docket_ids":["Docket No. PHMSA-2025-0776","PD-41(R)"],"dockets":[{"supporting_documents":[{"title":"California’s Reusability Mandate for Propane Cylinders","document_id":"PHMSA-2025-0776-0021"},{"title":"2.27.26 Congressional Letter","document_id":"PHMSA-2025-0776-0015"},{"title":"Worthington Preemption Application with Certification and Exhibits 1-6","document_id":"PHMSA-2025-0776-0002"}],"agency_name":"PHMSA","documents":[{"comment_count":0,"comment_start_date":"2026-09-10","updated_at":"2026-09-10T09:58:42.864-04:00","comment_url":"https://www.regulations.gov/commenton/PHMSA-2025-0776-0020","allow_late_comments":false,"id":"PHMSA-2025-0776-0020","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"PHMSA-2025-0776","title":"PHMSA Preemption Determination Application (PDA) 41(R)"}],"document_number":"2026-18501","effective_on":null,"end_page":57693,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/09/10/2026-18501.xml","html_url":"https://www.federalregister.gov/documents/2026/09/10/2026-18501/hazardous-materials-californias-reusability-mandate-for-propane-cylinders","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-18501?publication_date=2026-09-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-09-10/2026-18501/mods.xml","not_received_for_publication":null,"page_length":10,"page_views":{"count":314,"last_updated":"2026-10-24 20:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-09-10/pdf/2026-18501.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-18501.pdf?1788957920","publication_date":"2026-09-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/09/10/2026-18501.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"2.27.26 Congressional Letter","document_id":"PHMSA-2025-0776-0015"},{"title":"Worthington Preemption Application with Certification and Exhibits 1-6","document_id":"PHMSA-2025-0776-0002"}],"comments_count":0,"agency_id":"PHMSA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=PHMSA-2025-0776","supporting_documents_count":2,"docket_id":"PHMSA-2025-0776","document_id":"PHMSA-2025-0776-0020","regulation_id_number":null,"title":"PHMSA Preemption Determination Application (PDA) 41(R)","checked_regulationsdotgov_at":"2026-09-11T16:55:13Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":57684,"subtype":null,"title":"Hazardous Materials: California's Reusability Mandate for Propane Cylinders","toc_doc":"California's Reusability Mandate for Propane Cylinders","toc_subject":"Hazardous Materials","topics":[],"type":"Notice","volume":91}
