{"abstract":"The Environmental Protection Agency (EPA) is making a final determination that the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD- DE marginal ozone nonattainment area (the Philadelphia Area) has attained the 2008 ozone national ambient air quality standard (NAAQS) by the July 20, 2016 attainment date. This final determination is based on complete, certified, and quality assured ambient air quality monitoring data for the Philadelphia Area for the 2013-2015 monitoring period. The effect of this determination of attainment (DOA) is that the Philadelphia Area will not be bumped up or reclassified as a moderate nonattainment area. The determination of attainment is not equivalent to a redesignation, and the States in the Philadelphia Area must still meet the statutory requirements for redesignation in order to be redesignated to attainment. This determination is also not a clean data determination. This action is being taken under the Clean Air Act (CAA).","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/2017/11/02/2017-23226.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"82 FR 50814","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on December 4, 2017.","disposition_notes":null,"docket_ids":["EPA-R03-OAR-2016-0638","FRL-9969-93-Region 3"],"dockets":[],"document_number":"2017-23226","effective_on":"2017-12-04","end_page":50820,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2017/11/02/2017-23226.xml","html_url":"https://www.federalregister.gov/documents/2017/11/02/2017-23226/determination-of-attainment-by-the-attainment-date-for-the-2008-ozone-standard","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2017-23226?publication_date=2017-11-02","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2017-11-02/2017-23226/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":381,"last_updated":"2026-07-26 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2017-11-02/pdf/2017-23226.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2017-23226.pdf?1509540323","publication_date":"2017-11-02","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2017/11/02/2017-23226.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Delaware Brandywine/Martin Luther King Monitors DATA SUBSTITUTION ANALYSIS Technical Support Document","document_id":"EPA-R03-OAR-2016-0638-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R03-OAR-2016-0638","supporting_documents_count":1,"docket_id":"EPA-R03-OAR-2016-0638","regulation_id_number":null,"title":"Determination of Attainment by the Attainment Date for the 2008 Ozone NAAQS;  Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE  Nonattainment Area","checked_regulationsdotgov_at":"2017-11-22T06:00:16Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":50814,"subtype":null,"title":"Determination of Attainment by the Attainment Date for the 2008 Ozone Standard; Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE Nonattainment Area","toc_doc":"Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE Nonattainment Area; Determination of Attainment by the Attainment Date for the 2008 Ozone Standard","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Ozone","Reporting and recordkeeping requirements"],"type":"Rule","volume":82}
