{"abstract":"This final rule revises MSHA's Emergency Temporary Standard (ETS) and addresses sealing abandoned areas in underground coal mines. The final rule includes requirements for seal strength, design, construction, maintenance and repair of seals and monitoring and control of atmospheres behind seals in order to reduce the risk of seal failure and the risk of explosions in abandoned areas of underground coal mines. It also addresses the level of overpressure for new seals.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF LABOR","name":"Labor Department","id":271,"url":"https://www.federalregister.gov/agencies/labor-department","json_url":"https://www.federalregister.gov/api/v1/agencies/271","parent_id":null,"slug":"labor-department"},{"raw_name":"Mine Safety and Health Administration","name":"Mine Safety and Health Administration","id":288,"url":"https://www.federalregister.gov/agencies/mine-safety-and-health-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/288","parent_id":271,"slug":"mine-safety-and-health-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2008/04/18/08-1152.html","cfr_references":[{"chapter":null,"citation_url":null,"part":75,"title":30}],"citation":"73 FR 21182","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective April 18, 2008.","disposition_notes":null,"docket_ids":[],"dockets":[],"document_number":"08-1152","effective_on":"2008-04-18","end_page":21209,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2008/04/18/08-1152.xml","html_url":"https://www.federalregister.gov/documents/2008/04/18/08-1152/sealing-of-abandoned-areas","images":{"ER18AP08.010":{"original_size":"https://img.federalregister.gov/ER18AP08.010/ER18AP08.010_original_size.gif"},"ER18AP08.011":{"original_size":"https://img.federalregister.gov/ER18AP08.011/ER18AP08.011_original_size.gif"},"ER18AP08.012":{"original_size":"https://img.federalregister.gov/ER18AP08.012/ER18AP08.012_original_size.gif"},"ER18AP08.009":{"original_size":"https://img.federalregister.gov/ER18AP08.009/ER18AP08.009_original_size.gif"}},"images_metadata":{"ER18AP08.010":{"original_size":{"identifier":"ER18AP08.010","content_type":"image/gif","size":29666,"width":2777,"sha":"b302a912e18ad2bebdd08d4f22be691b","url":"https://img.federalregister.gov/ER18AP08.010/ER18AP08.010_original_size.gif","height":1640}},"ER18AP08.011":{"original_size":{"identifier":"ER18AP08.011","content_type":"image/gif","size":42620,"width":3334,"sha":"7c8a5ea30cc7e00ef19a4acaf1d14373","url":"https://img.federalregister.gov/ER18AP08.011/ER18AP08.011_original_size.gif","height":1901}},"ER18AP08.012":{"original_size":{"identifier":"ER18AP08.012","content_type":"image/gif","size":42741,"width":3358,"sha":"f5d863c3d869407e43af7f84e3f007e9","url":"https://img.federalregister.gov/ER18AP08.012/ER18AP08.012_original_size.gif","height":1894}},"ER18AP08.009":{"original_size":{"identifier":"ER18AP08.009","content_type":"image/gif","size":27624,"width":2670,"sha":"adbe8d61e49f8ffd359c0f99f1b5a342","url":"https://img.federalregister.gov/ER18AP08.009/ER18AP08.009_original_size.gif","height":1618}}},"json_url":"https://www.federalregister.gov/api/v1/documents/08-1152?publication_date=2008-04-18","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2008-04-18/08-1152/mods.xml","not_received_for_publication":null,"page_length":28,"page_views":{"count":522,"last_updated":"2026-07-28 12:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2008-04-18/pdf/08-1152.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2008-04-18","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2008/04/18/08-1152.txt","regulation_id_number_info":{"1219-AB52":{"issue":"200710","html_url":"https://www.federalregister.gov/regulations/1219-AB52/sealing-of-abandoned-areas","title":"Sealing of Abandoned Areas","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200710&RIN=1219-AB52&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["1219-AB52"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-14T03:24:15Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":21182,"subtype":null,"title":"Sealing of Abandoned Areas","toc_doc":"Sealing of Abandoned Areas","toc_subject":null,"topics":["Mine safety and health","Reporting and recordkeeping requirements"],"type":"Rule","volume":73}
