{"abstract":"The Environmental Protection Agency (EPA) is taking final action to approve in part and disapprove in part, the May 29, 2012, and July 26, 2012, State Implementation Plan (SIP) submissions, provided by the Mississippi Department of Environmental Quality (MDEQ) for inclusion into the Mississippi SIP. This final rulemaking pertains to the Clean Air Act (CAA or the Act) infrastructure requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an \"infrastructure\" SIP. MDEQ certified that the Mississippi SIP contains provisions that ensure the 2008 8-hour ozone NAAQS is implemented, enforced, and maintained in Mississippi (hereafter referred to as an \"infrastructure SIP submission\"). With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, interstate transport, visibility protection requirements and the state board majority requirements respecting significant portion of income, EPA is taking final action to approve Mississippi's infrastructure SIP submissions, provided to EPA on May 29, 2012, and July 26, 2012. EPA is taking final action to disapprove Mississippi's May 29, 2012, and July 26, 2012, SIP submissions with regards to the state board majority requirements respecting significant portion of income. EPA will consider action with regards to the infrastructure elements related to PSD permitting, visibility and interstate transport in a separate action.","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/2015/03/02/2015-04140.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"80 FR 11131","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule will be effective April 1, 2015.","disposition_notes":null,"docket_ids":["EPA-R04-OAR-2012-0698","FRL-9923-55-Region-4"],"dockets":[],"document_number":"2015-04140","effective_on":"2015-04-01","end_page":11133,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2015/03/02/2015-04140.xml","html_url":"https://www.federalregister.gov/documents/2015/03/02/2015-04140/approval-and-promulgation-of-implementation-plans-mississippi-infrastructure-requirements-for-the","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-04140?publication_date=2015-03-02","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2015-03-02/2015-04140/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":113,"last_updated":"2026-09-20 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2015-03-02/pdf/2015-04140.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-04140.pdf?1425046363","publication_date":"2015-03-02","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2015/03/02/2015-04140.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"MS EOY Grant Letter 3.28.2014","document_id":"EPA-R04-OAR-2012-0698-0006"},{"title":"Mississippi_Network_ Plan Response letter11_22_13","document_id":"EPA-R04-OAR-2012-0698-0005"},{"title":"5.8.2014E-mail_Mississippi Supplemental Letter and 2008 Ozone updated information","document_id":"EPA-R04-OAR-2012-0698-0004"},{"title":"07-26-2012 MS 2008 8 Hour Ozone Infrastructure SIP","document_id":"EPA-R04-OAR-2012-0698-0003"},{"title":"5.29.2012 2008 Ozone Infrastructure SIP Certification - Final - Complete with transmittal letter","document_id":"EPA-R04-OAR-2012-0698-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R04-OAR-2012-0698","supporting_documents_count":5,"docket_id":"EPA-R04-OAR-2012-0698","regulation_id_number":null,"title":"2008 8-hour Ozone Mississippi 110(a)(1) and (2) Infrastructure","checked_regulationsdotgov_at":"2015-03-22T06:00:08Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":11131,"subtype":null,"title":"Approval and Promulgation of Implementation Plans; Mississippi; Infrastructure Requirements for the 2008 8-Hour Ozone National Ambient Air Quality Standards","toc_doc":"Mississippi; Infrastructure Requirements for the 2008 8-Hour Ozone National Ambient Air Quality","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Nitrogen dioxide","Ozone","Reporting and recordkeeping requirements","Volatile organic compounds"],"type":"Rule","volume":80}
