{"abstract":"EPA is making two determinations regarding the Philadelphia- Wilmington-Atlantic City, PA-NJ-MD-DE 8-hour ozone moderate nonattainment area (the Philadelphia Area). First, EPA is determining that the Philadelphia Area has attained the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). This determination is based upon complete, quality assured, and certified ambient air monitoring data that show the area has monitored attainment of the 1997 8-hour ozone NAAQS for the 2008-2010 monitoring period. In accordance with EPA's applicable ozone implementation rule, this clean data determination suspends the requirement for the Philadelphia Area to submit an attainment demonstration, reasonably available control measures (RACM), a reasonable further progress (RFP) plan and contingency measures related to attainment of the 1997 8-hours ozone NAAQS. These requirements shall be suspended for so long as the area continues to attain the 1997 8-hour ozone NAAQS. Second, EPA is determining that the Philadelphia Area has attained the 1997 8-hour ozone NAAQS by its attainment date of June 15, 2011. These actions are 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/2012/03/26/2012-7196.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"77 FR 17341","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: This final rule is effective on April 25, 2012.","disposition_notes":null,"docket_ids":["EPA-R03-OAR-2011-0713","FRL-9652-6"],"dockets":[],"document_number":"2012-7196","effective_on":"2012-04-25","end_page":17344,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/03/26/2012-7196.xml","html_url":"https://www.federalregister.gov/documents/2012/03/26/2012-7196/approval-and-promulgation-of-air-quality-implementation-plans-delaware-maryland-new-jersey-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-7196?publication_date=2012-03-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-03-26/2012-7196/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":78,"last_updated":"2026-07-25 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-03-26/pdf/2012-7196.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-07196.pdf?1332506954","publication_date":"2012-03-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/03/26/2012-7196.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Technical Support Document Regarding Ozone Monitoring Data –Delaware, Maryland, New Jersey, and Pennsylvania; Determinations of Attainment of the 1997 8-Hour Ozone National Ambient Air Quality Standard for the Philadelphia-Wilmington-Atlantic City 8-Hour ","document_id":"EPA-R03-OAR-2011-0713-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R03-OAR-2011-0713","supporting_documents_count":1,"docket_id":"EPA-R03-OAR-2011-0713","regulation_id_number":null,"title":"Delaware, Maryland, New Jersey, and Pennsylvania- Determinations of Attainment of the 1997 8-Hour Ozone National Ambient Air Quality Standard for the Philadelphia-Wilmington-Atlantic City 8-Hour Ozone Moderate Nonattainment Area","checked_regulationsdotgov_at":"2012-04-27T21:52:56Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":17341,"subtype":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; Delaware, Maryland, New Jersey, and Pennsylvania; Determinations of Attainment of the 1997 8-Hour Ozone Standard for the Philadelphia-Wilmington-Atlantic City Moderate Nonattainment Area","toc_doc":"Delaware, Maryland, New Jersey, and Pennsylvania; Determinations of Attainment of 1997 8-Hour Ozone, etc.","toc_subject":"Approvals and Promulgations of Air Quality Implementation Plans:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Ozone","Reporting and recordkeeping requirements"],"type":"Rule","volume":77}
