{"abstract":"The Environmental Protection Agency (EPA) is approving elements of State Implementation Plan (SIP) submissions from the State of Texas for Ozone (O<INF>3</INF>) and Nitrogen Dioxide (NO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). These submittals address how the existing SIP provides for implementation, maintenance, and enforcement of the 2008 O<INF>3</INF> and 2010 NO<INF>2</INF> NAAQS (infrastructure SIPs or i-SIPs). These i-SIPs ensure that the State's SIP is adequate to meet the State's responsibilities under the Federal 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/2016/09/09/2016-21593.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"81 FR 62375","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on October 11, 2016.","disposition_notes":null,"docket_ids":["EPA-R06-OAR-2012-0953","FRL-9950-77-Region 6"],"dockets":[],"document_number":"2016-21593","effective_on":"2016-10-11","end_page":62378,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/09/09/2016-21593.xml","html_url":"https://www.federalregister.gov/documents/2016/09/09/2016-21593/approval-and-promulgation-of-air-quality-implementation-plans-texas-infrastructure-or-requirements","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-21593?publication_date=2016-09-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-09-09/2016-21593/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":102,"last_updated":"2026-07-26 14:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-09-09/pdf/2016-21593.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-21593.pdf?1473338731","publication_date":"2016-09-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/09/09/2016-21593.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"TX144.06 EPA Guidance on Infrastructure State Implementation Plan Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2), September 2013. 62 pages v7a v9v","document_id":"EPA-R06-OAR-2012-0953-0006"},{"title":"TX144.05 Additional Materials for TSD","document_id":"EPA-R06-OAR-2012-0953-0005"},{"title":"TX144.04 Texas Infrastructure and Transport SIP for the 2008 Ozone NAAQS, Texas Project No. 2012-004-SIP-NR, submitted to EPA December 13, 2012 (TX-339, SIP). 155 pages 10.9 MB w28","document_id":"EPA-R06-OAR-2012-0953-0004"},{"title":"TX144.03 Texas Infrastructure and Transport SIP for the 2010 Nitrogen Dioxide NAAQS, Texas Project No. 2012-016-SIP-NR, submitted to EPA December 7, 2012 (TX-338, SIP).  118 pages 2.9 MB w28","document_id":"EPA-R06-OAR-2012-0953-0003"},{"title":"TX144.02 Technical Support Document for Infrastructure Requirements for the 2008 Ozone and 2010 Nitrogen Dioxide National Ambient Air Quality Standards. 19 pages.","document_id":"EPA-R06-OAR-2012-0953-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R06-OAR-2012-0953","supporting_documents_count":5,"docket_id":"EPA-R06-OAR-2012-0953","regulation_id_number":null,"title":"TX144 Texas Infrastructure or Requirements for the 2008 Ozone and 2010 Nitrogen Dioxide National Ambient Air Quality Standards","checked_regulationsdotgov_at":"2016-09-29T06:00:20Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":62375,"subtype":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; Texas; Infrastructure or Requirements for the 2008 Ozone and 2010 Nitrogen Dioxide National Ambient Air Quality Standards","toc_doc":"Texas; Infrastructure or Requirements for the 2008 Ozone and 2010 Nitrogen Dioxide National Ambient Air Quality Standards","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"],"type":"Rule","volume":81}
