{"abstract":"The Environmental Protection Agency (EPA) is redesignating the Indiana portion of the Cincinnati-Hamilton, OH-IN-KY, nonattainment area (hereafter, \"the Cincinnati-Hamilton area\") to attainment for the 1997 fine particulate matter (PM<INF>2.5</INF>) annual national ambient air quality standard (NAAQS or standard). The Indiana portion of the Cincinnati-Hamilton area includes Lawrenceburg Township within Dearborn County. Because EPA has determined that the Cincinnati- Hamilton area is attaining this annual PM<INF>2.5</INF> standard, EPA is redesignating the area to attainment and also approving several additional related actions. First, EPA is approving an update to the Indiana State implementation plan (SIP) by updating the state's approved plan for maintaining the 1997 annual PM<INF>2.5</INF> NAAQS through 2027. In addition, EPA previously approved the base year emissions inventory for the Cincinnati-Hamilton area, and is approving Indiana's updated emissions inventory which includes emissions inventories for volatile organic compounds (VOCs) and ammonia. Indiana's approved maintenance plan submission also includes a budget for the mobile source contribution of PM<INF>2.5</INF> and nitrogen oxides (NO<INF>X</INF>) to the Cincinnati-Hamilton area for transportation conformity purposes, which EPA is approving. EPA is taking these actions in accordance with the Clean Air Act (CAA) and EPA's implementation rule regarding the 1997 PM<INF>2.5</INF> NAAQS.","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/2017/09/01/2017-18498.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40},{"chapter":null,"citation_url":null,"part":81,"title":40}],"citation":"82 FR 41527","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective September 1, 2017.","disposition_notes":null,"docket_ids":["EPA-R05-OAR-2016-0513","FRL-9967-17-Region 5"],"dockets":[],"document_number":"2017-18498","effective_on":"2017-09-01","end_page":41529,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2017/09/01/2017-18498.xml","html_url":"https://www.federalregister.gov/documents/2017/09/01/2017-18498/air-plan-approval-indiana-redesignation-of-the-indiana-portion-of-the-cincinnati-hamilton-oh-in-ky","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2017-18498?publication_date=2017-09-01","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2017-09-01/2017-18498/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":91,"last_updated":"2026-10-23 04:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2017-09-01/pdf/2017-18498.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2017-18498.pdf?1504183531","publication_date":"2017-09-01","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2017/09/01/2017-18498.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Revised 1997 PM2.5 (annual)  Redesignation for Indiana portion of Cincinnati Area, 08/19/2016 submittal","document_id":"EPA-R05-OAR-2016-0513-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R05-OAR-2016-0513","supporting_documents_count":1,"docket_id":"EPA-R05-OAR-2016-0513","regulation_id_number":null,"title":"Revised 1997 PM2.5 (annual)  Redesignation for Indiana portion of Cincinnati Area","checked_regulationsdotgov_at":"2017-09-21T06:00:19Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":41527,"subtype":null,"title":"Air Plan Approval; Indiana; Redesignation of the Indiana Portion of the Cincinnati-Hamilton, OH-IN-KY Area to Attainment of the 1997 Annual Standard for Fine Particulate Matter","toc_doc":"Indiana; Redesignation of Indiana Portion of Cincinnati-Hamilton, OH-IN-KY Area to Attainment of 1997 Annual Standard for Fine Particulate Matter","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Particulate matter","Wilderness areas"],"type":"Rule","volume":82}
