{"abstract":"EPA is approving most elements of submittals from the States of Connecticut, Maine, Massachusetts, and New Hampshire. We are also conditionally approving certain elements of these submittals, as well as disapproving a few elements of Massachusetts' submittals. The submittals outline how each state's State Implementation Plan (SIP) meets the requirements of section 110(a) of the Clean Air Act (CAA) for both the 1997 and 2006 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS). These actions are being taken under the Clean Air Act.","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/2012/10/16/2012-25300.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"77 FR 63228","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on November 15, 2012.","disposition_notes":null,"docket_ids":["EPA-R01-OAR-2011-0317 and EPA-R01-OAR-2011-0321 (CT)","EPA-R01-OAR-2011-0318 and EPA-R01-OAR-2011-0322 (ME)","EPA-R01-OAR-2009-0459 and EPA-R01-OAR-2011-0323 (MA)","EPA-R01-OAR-2009-0460 and EPA-R01-OAR-2011-0324 (NH)","A-1-FRL-9740-1"],"dockets":[],"document_number":"2012-25300","effective_on":"2012-11-15","end_page":63234,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/10/16/2012-25300.xml","html_url":"https://www.federalregister.gov/documents/2012/10/16/2012-25300/approval-and-promulgation-of-air-quality-implementation-plans-connecticut-maine-massachusetts-new","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-25300?publication_date=2012-10-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-10-16/2012-25300/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":96,"last_updated":"2026-07-28 04:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-10-16/pdf/2012-25300.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-25300.pdf?1350305303","publication_date":"2012-10-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/10/16/2012-25300.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"CT - SIP supplement Jan 7, 2011","document_id":"EPA-R01-OAR-2011-0321-0010"},{"title":"EPA Technical Support Document July 10, 2012.","document_id":"EPA-R01-OAR-2011-0321-0007"},{"title":"Infrastructure SIPs for the 1997 and 2006 Fine Particulate Matter Standards, State Letter July 11, 2012.","document_id":"EPA-R01-OAR-2011-0321-0006"},{"title":"Addendum to the CAA 110(a)(2)(D)(i)(l) Portion of Connecticut's Infrastructure Submittal for the 2006 PM2.5 NAAQS, State Letter August 19, 2011.","document_id":"EPA-R01-OAR-2011-0321-0005"},{"title":"Infrastructure SIPs for the 1997 and 2006 Fine Particulate Matter Standards, State Letter June 15, 2011.","document_id":"EPA-R01-OAR-2011-0321-0004"},{"title":"Adequacy Determination of the Connecticut SIP for CAA 110(a)(1) and (2)","document_id":"EPA-R01-OAR-2011-0321-0003"},{"title":"Adequacy Determination of the Connecticut SIP for CAA 110(a)(1) and (2) Cover Letter September 18, 2009.","document_id":"EPA-R01-OAR-2011-0321-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R01-OAR-2011-0321","supporting_documents_count":7,"docket_id":"EPA-R01-OAR-2011-0321","regulation_id_number":null,"title":"Approval of State Implementation Plan Revision: Connecticut; Section 110(a) Infrastructure SIP for the 2006 PM2.5 NAAQS\r\n","checked_regulationsdotgov_at":"2012-11-05T06:00:08Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":63228,"subtype":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; Connecticut, Maine, Massachusetts, New Hampshire; Infrastructure SIPs for the 1997 and 2006 Fine Particulate Matter Standards","toc_doc":"Connecticut, Maine, Massachusetts, New Hampshire; Infrastructure SIPs for 1997","toc_subject":"Approvals and Promulgations of Air Quality Implementation Plans:","topics":["Air pollution control","Carbon monoxide","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":77}
