{"abstract":"The Pipeline and Hazardous Materials Safety Administration (PHMSA) is amending the Hazardous Materials Regulations by establishing standards for the safe transportation of explosives on cargo tank motor vehicles and multipurpose bulk trucks transporting materials for blasting operations. This rulemaking is responsive to two petitions for rulemaking submitted by industry representatives: P-1557, concerning the continued use of renewal applications, and P-1583, concerning the incorporation of an industry standard publication. Further, developing these requirements provides wider access to the regulatory flexibility currently only offered by special permits and competent authorities. The requirements of this final rule mirror the majority of provisions contained in nine widely-used longstanding special permits that have established safety records. These requirements eliminate the need for future renewal requests, thus reducing paperwork burdens and facilitating commerce while maintaining a commensurate level of safety. This final rule authorizes the transportation of certain explosives, ammonium nitrates, ammonium nitrate emulsions, and other specific hazardous materials in both non-bulk and bulk packagings, which are not otherwise authorized under current regulations. These hazardous materials are used in blasting operations on cargo tank motor vehicles and specialized vehicles, known as multipurpose bulk trucks, which are used as mobile work platforms to create blends of explosives that are unique to each blast site. Finally, this rulemaking addresses the construction of new multipurpose bulk trucks.","action":"Final rule.","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/2015/12/21/2015-31880.html","cfr_references":[{"chapter":null,"citation_url":null,"part":171,"title":49},{"chapter":null,"citation_url":null,"part":172,"title":49},{"chapter":null,"citation_url":null,"part":173,"title":49},{"chapter":null,"citation_url":null,"part":177,"title":49}],"citation":"80 FR 79424","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: This final rule is effective January 20, 2016.","disposition_notes":null,"docket_ids":["Docket No. PHMSA-2011-0345 (HM-233D)"],"dockets":[],"document_number":"2015-31880","effective_on":"2016-01-20","end_page":79453,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2015/12/21/2015-31880.xml","html_url":"https://www.federalregister.gov/documents/2015/12/21/2015-31880/hazardous-materials-requirements-for-the-safe-transportation-of-bulk-explosives-rrr","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-31880?publication_date=2015-12-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2015-12-21/2015-31880/mods.xml","not_received_for_publication":null,"page_length":30,"page_views":{"count":4771,"last_updated":"2026-04-04 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2015-12-21/pdf/2015-31880.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-31880.pdf?1450446329","publication_date":"2015-12-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2015/12/21/2015-31880.txt","regulation_id_number_info":{"2137-AE86":{"issue":"201510","html_url":"https://www.federalregister.gov/regulations/2137-AE86/hazardous-materials-requirements-for-the-safe-transportation-of-bulk-explosives-rrr","title":"Hazardous Materials: Requirements for the Safe Transportation of Bulk Explosives RRR","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201510&RIN=2137-AE86&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2137-AE86"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"U.S. DOT/PHMSA - Regulatory Analysis for the Notice of Proposed Rulemaking (NPRM)","document_id":"PHMSA-2011-0345-0004"},{"title":"Institute of Makers of Explosives - Supplemental Information - SLP-23 October 2011 version","document_id":"PHMSA-2011-0345-0003"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=PHMSA-2011-0345","supporting_documents_count":2,"docket_id":"PHMSA-2011-0345","regulation_id_number":null,"title":"Hazardous Materials: Incorporation of Special Permits Authorizing the Transportation of Bulk Explosives","checked_regulationsdotgov_at":"2016-01-10T06:00:14Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":79424,"subtype":null,"title":"Hazardous Materials: Requirements for the Safe Transportation of Bulk Explosives (RRR)","toc_doc":"Hazardous Materials:  Requirements for the Safe Transportation of Bulk Explosives","toc_subject":null,"topics":["Exports","Hazardous materials transportation","Hazardous waste","Imports","Incorporation by reference","Labeling","Packaging and containers","Radioactive materials","Reporting and recordkeeping requirements","Security measures","Uranium"],"type":"Rule","volume":80}
