{"abstract":"The Environmental Protection Agency is finalizing revisions and confidentiality determinations for the petroleum and natural gas systems source category of the Greenhouse Gas Reporting Program. In particular, this action adds new monitoring methods for detecting leaks from oil and gas equipment in the petroleum and natural gas systems source category consistent with the fugitive emissions monitoring methods in the recently finalized new source performance standards for the oil and gas industry. This action also adds emission factors for leaking equipment to be used in conjunction with these monitoring methods to calculate and report greenhouse gas emissions resulting from equipment leaks. Finally, this action finalizes reporting requirements and confidentiality determinations for nine new or substantially revised data elements contained in these amendments.","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/2016/11/30/2016-27981.html","cfr_references":[{"chapter":null,"citation_url":null,"part":98,"title":40}],"citation":"81 FR 86490","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on January 1, 2017.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2015-0764","FRL-9955-12-OAR"],"dockets":[],"document_number":"2016-27981","effective_on":"2017-01-01","end_page":86519,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/11/30/2016-27981.xml","html_url":"https://www.federalregister.gov/documents/2016/11/30/2016-27981/greenhouse-gas-reporting-rule-leak-detection-methodology-revisions-and-confidentiality","images":{"ER30NO16.001":{"large":"https://img.federalregister.gov/ER30NO16.001/ER30NO16.001_large.png","original_size":"https://img.federalregister.gov/ER30NO16.001/ER30NO16.001_original_size.png"},"ER30NO16.000":{"large":"https://img.federalregister.gov/ER30NO16.000/ER30NO16.000_large.png","original_size":"https://img.federalregister.gov/ER30NO16.000/ER30NO16.000_original_size.png"}},"images_metadata":{"ER30NO16.001":{"large":{"identifier":"ER30NO16.001","content_type":"image/png","size":5254,"width":753,"sha":"8d2fea0b466c26760614ad8e17272d7c","url":"https://img.federalregister.gov/ER30NO16.001/ER30NO16.001_large.png","height":155},"original_size":{"identifier":"ER30NO16.001","content_type":"image/png","size":6673,"width":2674,"sha":"e55955f97e86e0f156fdd797bae88ea3","url":"https://img.federalregister.gov/ER30NO16.001/ER30NO16.001_original_size.png","height":549}},"ER30NO16.000":{"large":{"identifier":"ER30NO16.000","content_type":"image/png","size":3544,"width":793,"sha":"12d6f6782d71260b742dc0bd9bfa1705","url":"https://img.federalregister.gov/ER30NO16.000/ER30NO16.000_large.png","height":67},"original_size":{"identifier":"ER30NO16.000","content_type":"image/png","size":4695,"width":2817,"sha":"cd70c57a2f43e31196b42fb87fe43fad","url":"https://img.federalregister.gov/ER30NO16.000/ER30NO16.000_original_size.png","height":239}}},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-27981?publication_date=2016-11-30","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-11-30/2016-27981/mods.xml","not_received_for_publication":null,"page_length":30,"page_views":{"count":1733,"last_updated":"2026-09-20 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-11-30/pdf/2016-27981.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-27981.pdf?1480427148","publication_date":"2016-11-30","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/11/30/2016-27981.txt","regulation_id_number_info":{"2060-AS73":{"issue":"201610","html_url":"https://www.federalregister.gov/regulations/2060-AS73/greenhouse-gas-reporting-rule-leak-detection-methodology-revisions-and-confidentiality-determination","title":"Greenhouse Gas Reporting Rule: Leak Detection Methodology Revisions and Confidentiality Determinations for Petroleum and Natural Gas Systems","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201610&RIN=2060-AS73&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AS73"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Subpart W—Petroleum and Natural Gas Systems: Redline/strikeout document showing changes to subpart W regulatory text in the final action: Greenhouse Gas Reporting Rule: Leak Detection Methodology Revisions and Confidentiality Determinations for Petroleum ","document_id":"EPA-HQ-OAR-2015-0764-0068"},{"title":"Greenhouse Gas Reporting Rule: Technical Support for Leak Detection Methodology Revisions and Confidentiality Determinations for Petroleum and Natural Gas Systems","document_id":"EPA-HQ-OAR-2015-0764-0066"},{"title":"Supporting Statement: Environmental Protection Agency--Greenhouse Gas Reporting Rule: Leak Detection Methodology Revisions and Confidentiality Determinations for Petroleum and Natural Gas Systems;
