{"abstract":"The Environmental Protection Agency (EPA) is approving most elements of State Implementation Plan (SIP) submissions from Massachusetts regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 1997 ozone, 2008 lead (Pb), 2008 ozone, 2010 nitrogen dioxide (NO<INF>2</INF>), and 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). EPA is also conditionally approving three aspects of the Commonwealth's submittals. In addition, we are also making findings of failure to submit pertaining to various aspects of the prevention of significant deterioration (PSD) requirements of infrastructure SIPs. Lastly, we are removing 40 CFR 52.1160 as legally obsolete. This action is being taken in accordance with 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/2016/12/21/2016-30466.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"81 FR 93627","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on January 20, 2017.","disposition_notes":null,"docket_ids":["EPA-R01-OAR-2014-0720","A-1-FRL-9952-94-Region 1"],"dockets":[],"document_number":"2016-30466","effective_on":"2017-01-20","end_page":93631,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/12/21/2016-30466.xml","html_url":"https://www.federalregister.gov/documents/2016/12/21/2016-30466/air-plan-approval-ma-infrastructure-state-implementation-plan-requirements","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-30466?publication_date=2016-12-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-12-21/2016-30466/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":135,"last_updated":"2026-04-24 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-12-21/pdf/2016-30466.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-30466.pdf?1482241529","publication_date":"2016-12-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/12/21/2016-30466.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"MA.Pb.CoverLtr.and.PubHearingCert","document_id":"EPA-R01-OAR-2014-0720-0026"},{"title":"MA.Pb.ISIP.Submittal","document_id":"EPA-R01-OAR-2014-0720-0025"},{"title":"MA_1997-OzoneISIP.Ltr-Dec-07","document_id":"EPA-R01-OAR-2014-0720-0024"},{"title":"MA_1997-OzoneISIP","document_id":"EPA-R01-OAR-2014-0720-0023"},{"title":"MA-MultiP.June-6-14.2008-Ozone-ISIP","document_id":"EPA-R01-OAR-2014-0720-0022"},{"title":"MA-MultiP.June-6-14.2010-NO2-ISIP","document_id":"EPA-R01-OAR-2014-0720-0021"},{"title":"MA-MultiP.June-6-14.2010-SO2-ISIP","document_id":"EPA-R01-OAR-2014-0720-0020"},{"title":"MA-MultiP.June-6-14.Cover&HearingCert","document_id":"EPA-R01-OAR-2014-0720-0019"},{"title":"MA-MultiP.June-6-14.Response-to-Com","document_id":"EPA-R01-OAR-2014-0720-0018"},{"title":"Guidance.2007.ozoneANDpm","document_id":"EPA-R01-OAR-2014-0720-0017"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R01-OAR-2014-0720","supporting_documents_count":25,"docket_id":"EPA-R01-OAR-2014-0720","regulation_id_number":null,"title":"Air Plan Approval; Massachusetts; Infrastructure State Implementation Plan Requirements","checked_regulationsdotgov_at":"2017-01-10T06:00:18Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":93627,"subtype":null,"title":"Air Plan Approval; MA; Infrastructure State Implementation Plan Requirements","toc_doc":"Massachusetts; Infrastructure State Implementation Plan Requirements","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","Reporting and recordkeeping requirements","Sulfur oxides","Volatile organic compounds"],"type":"Rule","volume":81}
