{"abstract":"The Environmental Protection Agency (EPA) is finalizing requirements that state, local and tribal air agencies would have to meet as they implement the current and future national ambient air quality standards (NAAQS) for fine particulate matter (PM<INF>2.5</INF>). Specifically, this document provides details on meeting the statutory state implementation plan (SIP) requirements that apply to areas designated nonattainment for any PM<INF>2.5</INF> NAAQS, such as: General requirements for attainment plan due dates and attainment dates; emissions inventories; attainment demonstrations; provisions for demonstrating reasonable further progress; quantitative milestones; contingency measures; and nonattainment New Source Review (NNSR) permitting programs, among other things. This rule clarifies the specific attainment planning requirements that apply to PM<INF>2.5</INF> NAAQS nonattainment areas based on their classification (either Moderate or Serious), and the process for reclassifying Moderate areas to Serious. Additionally, in this document the EPA is revoking the 1997 primary annual standard for areas designated as attainment for that standard because the EPA revised the primary annual standard in 2012. The EPA first established the PM<INF>2.5</INF> NAAQS in 1997, completed a review and revision of those standards in 2006, and most recently completed a review and revision of the PM<INF>2.5</INF> NAAQS on December 14, 2012.","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/2016/08/24/2016-18768.html","cfr_references":[{"chapter":null,"citation_url":null,"part":50,"title":40},{"chapter":null,"citation_url":null,"part":51,"title":40},{"chapter":null,"citation_url":null,"part":93,"title":40}],"citation":"81 FR 58010","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on October 24, 2016.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2013-0691","FRL-9946-36-OAR"],"dockets":[],"document_number":"2016-18768","effective_on":"2016-10-24","end_page":58162,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/08/24/2016-18768.xml","html_url":"https://www.federalregister.gov/documents/2016/08/24/2016-18768/fine-particulate-matter-national-ambient-air-quality-standards-state-implementation-plan","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-18768?publication_date=2016-08-24","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-08-24/2016-18768/mods.xml","not_received_for_publication":null,"page_length":153,"page_views":{"count":3713,"last_updated":"2026-07-26 06:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-08-24/pdf/2016-18768.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-18768.pdf?1471956328","publication_date":"2016-08-24","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/08/24/2016-18768.txt","regulation_id_number_info":{"2060-AQ48":{"issue":"201604","html_url":"https://www.federalregister.gov/regulations/2060-AQ48/fine-particulate-matter-national-ambient-air-quality-standards-state-implementation-plan-requirement","title":"Fine Particulate Matter National Ambient Air Quality Standards: State Implementation Plan Requirements","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201604&RIN=2060-AQ48&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2060-AQ48"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Information Collection Request Supporting Statement for the Implementation of the Fine Particulate Matter National Ambient Air Quality Standards (ICR No. 2258.05, OMB 2060-0611)","document_id":"EPA-HQ-OAR-2013-0691-0149"},{"title":"API remarks for public hearing on PM 25 SIP Requests Proposed Rule April 29 2015","document_id":"EPA-HQ-OAR-2013-0691-0143"},{"title":"Public hearing transcript PM 25 SIP Requests Proposed Rule April 29, 2015","document_id":"EPA-HQ-OAR-2013-0691-0142"},{"title":"Email Damberg to Szabo EPA response 2 to comments on PM25 SIP Reqts Rule July 15 2016","document_id":"EPA-HQ-OAR-2013-0691-0136"},{"title":"Presentation to OMB and the Interagency Reviewers on 05/13/2016","document_id":"EPA-HQ-OAR-2013-0691-0129"},{"title":"Document submitted to initiate E.O. 12866 review -
