{"abstract":"EPA is proposing to take action on portions of State Implementation Plan (SIP) revisions submitted by the State of Oklahoma to address Clean Air Act requirements that prohibit air emissions which will contribute significantly to nonattainment in, or interfere with maintenance by, any other State for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards), the 1997 fine particulate matter (PM<INF>2.5</INF>) NAAQS and the 2006 24-hour PM<INF>2.5</INF> NAAQS. EPA is basing these proposed actions on the final determinations concluded within the Cross State Air Pollution Rule (CSAPR or Transport Rule) and proposed determination within the Supplemental Notice of Proposed Rulemaking (SNPR). EPA is proposing to disapprove, or in the alternative, approve the portion of the submittal demonstrating Oklahoma does not interfere with maintenance of the ozone NAAQS in other states. EPA intends to finalize approval or disapproval based on its final determination for the SNPR regarding Oklahoma for the ozone NAAQS. EPA is also proposing to approve the portion of the submittal demonstrating Oklahoma does not contribute significantly to nonattainment of the ozone NAAQS in other states. Finally, EPA is proposing to approve the portions of the submittals addressing Oklahoma's impacts for the PM<INF>2.5</INF> NAAQS in other states. This action is being taken under section 110 of the CAA.","action":"Proposed 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/2011/10/17/2011-26763.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"76 FR 64065","comment_url":null,"comments_close_on":"2011-11-16","correction_of":null,"corrections":[],"dates":"Written comments must be received on or before November 16, 2011.","disposition_notes":null,"docket_ids":["EPA-R06-OAR-2007-0314","FRL-9479-9"],"dockets":[],"document_number":"2011-26763","effective_on":null,"end_page":64069,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2011/10/17/2011-26763.xml","html_url":"https://www.federalregister.gov/documents/2011/10/17/2011-26763/approval-and-promulgation-of-implementation-plans-oklahoma-interstate-transport-of-pollution","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2011-26763?publication_date=2011-10-17","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2011-10-17/2011-26763/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":76,"last_updated":"2026-10-25 00:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2011-10-17/pdf/2011-26763.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2011-10-17","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2011/10/17/2011-26763.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"OK006.32 August 8, 2011, Federal Register Notice “Federal Implementation Plans: Interstate Transport of Fine Particulate Matter and Ozone and Correction of SIP Approvals”.","document_id":"EPA-R06-OAR-2007-0314-0032"},{"title":"OK006.31 September 25, 2009 EPA Memo “Guidance on SIP Elements Required Under Sections 110(a)(1) and (2) for the 2006 24-Hour Fine Particle (PM25) National Ambient Air Quality Standards (NAAQS)”.","document_id":"EPA-R06-OAR-2007-0314-0031"},{"title":"OK006.30 August 15, 2006 EPA Memo “Guidance for State Implementation Plan (SIP) Submissions to Meet Current Outstanding Obligations Under Section 110(a)(2)(D)(i) for the 8-Hour Ozone and PM2.5 National Ambient Air Quality Standards”.","document_id":"EPA-R06-OAR-2007-0314-0030"},{"title":"OK006.26  April 5, 2011 State Submittal: Certification of SIP Elements for the 2006 24-hour PM2.5 NAAQS under Clean Air Act Sections 110(a)(1)-(2).  13 pages r4e","document_id":"EPA-R06-OAR-2007-0314-0026"},{"title":"OK006.24 Congressional Review. 6 pages nyp","document_id":"EPA-R06-OAR-2007-0314-0024"},{"title":"OK006.23 March 23, 2010, EPA memorandum, “Modeling Procedures for Demonstrating Compliance with PM2.5 NAAQS”, from Stephen D.
