{"abstract":"The Environmental Protection Agency (EPA) is approving elements of State Implementation Plan (SIP) submissions from Connecticut regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2008 lead, 2008 ozone, 2010 nitrogen dioxide, and 2010 sulfur dioxide National Ambient Air Quality Standards (NAAQS). EPA is also converting conditional approvals for several infrastructure requirements for the 1997 ozone NAAQS and for the 1997 and 2006 fine particle (PM<INF>2.5</INF>) NAAQS to full approval under the CAA. Furthermore, we are conditionally approving elements of Connecticut's infrastructure requirements of the CAA regarding prevention of significant deterioration requirements to treat nitrogen oxides as a precursor to ozone and to establish a minor source baseline date for PM<INF>2.5</INF> emissions. Lastly, EPA is approving three statutes submitted by Connecticut in support of its demonstration that the infrastructure requirements of the CAA have been met. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the 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/2016/06/03/2016-12375.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"81 FR 35636","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on July 5, 2016.","disposition_notes":null,"docket_ids":["EPA-R01-OAR-2015-0198","FRL-9940-14-Region 1"],"dockets":[],"document_number":"2016-12375","effective_on":"2016-07-05","end_page":35641,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/06/03/2016-12375.xml","html_url":"https://www.federalregister.gov/documents/2016/06/03/2016-12375/approval-and-promulgation-of-implementation-plans-connecticut-infrastructure-requirements-for-lead","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-12375?publication_date=2016-06-03","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-06-03/2016-12375/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":219,"last_updated":"2026-10-23 10:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-06-03/pdf/2016-12375.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-12375.pdf?1464871545","publication_date":"2016-06-03","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/06/03/2016-12375.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"so2_designation_tsd_final_13mar2013","document_id":"EPA-R01-OAR-2015-0198-0030"},{"title":"SO2 point sources in 2014 NEI","document_id":"EPA-R01-OAR-2015-0198-0029"},{"title":"march 14 2013 cover letter for so2 modeling","document_id":"EPA-R01-OAR-2015-0198-0028"},{"title":"Copy of so2_designvalues_20132015_final_07_29_16","document_id":"EPA-R01-OAR-2015-0198-0027"},{"title":"2016 AMPD data","document_id":"EPA-R01-OAR-2015-0198-0026"},{"title":"2014 NEI Tier 2 data","document_id":"EPA-R01-OAR-2015-0198-0025"},{"title":"2014 NEI Tier 1 data","document_id":"EPA-R01-OAR-2015-0198-0024"},{"title":"2013 Guidance on SIP elements for all NAAQS","document_id":"EPA-R01-OAR-2015-0198-0021"},{"title":"2009 Guidance on SIP elements for 2006 PM2.5 NAAQS","document_id":"EPA-R01-OAR-2015-0198-0020"},{"title":"2007 Guidance on SIP elements for 1997 Ozone and PM2.5 NAAQS","document_id":"EPA-R01-OAR-2015-0198-0019"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R01-OAR-2015-0198","supporting_documents_count":27,"docket_id":"EPA-R01-OAR-2015-0198","regulation_id_number":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Infrastructure State Implementation Plan Requirements for the 2008 lead (Pb), 2008 8-hr ozone (O3), 2010 nitrogen dioxide (NO2), 2010 sulfur dioxide (SO2) NAAQSs, and several infrastructure requirements for the 1997 and 2006 fine particle (PM2.5) NAAQSs.","checked_regulationsdotgov_at":"2016-06-23T06:00:14Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":35636,"subtype":null,"title":"Approval and Promulgation of Implementation Plans; Connecticut; Infrastructure Requirements for Lead, Ozone, Nitrogen Dioxide, Sulfur Dioxide, and Fine Particulate Matter","toc_doc":"Connecticut; Infrastructure Requirements for Lead, Ozone, Nitrogen Dioxide, Sulfur Dioxide, and Fine Particulate Matter","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Lead","Nitrogen dioxide","Ozone","Particulate matter","Reporting and recordkeeping requirements","Sulfur oxides","Volatile organic compounds"],"type":"Rule","volume":81}
