{"abstract":"The Environmental Protection Agency (EPA) is approving elements of State Implementation Plan (SIP) submissions from New Hampshire regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2008 lead, 2008 ozone, and 2010 nitrogen dioxide National Ambient Air Quality Standards (NAAQS). EPA is also converting conditional approvals for several infrastructure requirements for the 1997 and 2006 fine particle (PM<INF>2.5</INF>) NAAQS to full approval under the CAA. Furthermore, we are updating the classification for one of New Hampshire's air quality control regions for ozone based on recent air quality monitoring data collected by the state, and are granting the state's request for an exemption from the infrastructure SIP contingency plan obligation for ozone. Last, we are conditionally approving certain elements of New Hampshire's submittal relating to prevention of significant deterioration requirements. 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/2015/12/16/2015-31525.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"80 FR 78135","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on January 15, 2016.","disposition_notes":null,"docket_ids":["EPA-R01-OAR-2012-0950","A-1-FRL-9940-15-Region 1"],"dockets":[],"document_number":"2015-31525","effective_on":"2016-01-15","end_page":78141,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2015/12/16/2015-31525.xml","html_url":"https://www.federalregister.gov/documents/2015/12/16/2015-31525/air-plan-approval-nh-infrastructure-state-implementation-plan-requirements-for-ozone-lead-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-31525?publication_date=2015-12-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2015-12-16/2015-31525/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":139,"last_updated":"2026-04-23 22:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2015-12-16/pdf/2015-31525.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-31525.pdf?1450187130","publication_date":"2015-12-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2015/12/16/2015-31525.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Updated.Withdrawal.Attachement","document_id":"EPA-R01-OAR-2012-0950-0025"},{"title":"NH-Withdrawal.Ltr.12-29-15","document_id":"EPA-R01-OAR-2012-0950-0024"},{"title":"EPA Guidance on  Infrastructure State Implementation Plan (SIP) Elements Under Clean Air Act Sections 110(a)(l) and 110(a)(2), dated September 13, 2013.","document_id":"EPA-R01-OAR-2012-0950-0021"},{"title":"EPA Guidance on  \"Infrastructure\" Elements for SIPs Required Under Sections 110(a)(l) and (2) for the 2008 Lead (Pb) National Ambient Air Quality Standards, dated October 14, 2011.","document_id":"EPA-R01-OAR-2012-0950-0020"},{"title":"EPA Guidance on  \"Infrastructure\" Elements for SIPs Required Under Sections 110(a)(l) and (2) for the 2006 24-Hour Fine Particle (PM2.5) National Ambient Air Quality Standards, dated September 25, 2009.","document_id":"EPA-R01-OAR-2012-0950-0019"},{"title":"EPA Guidance on  \"Infrastructure\" Elements for SIPs Required Under Sections 110(a)(l) and (2) for the 1997 8-hour Ozone and PM2.s National Ambient Air Quality Standards, dated October 2, 2007.","document_id":"EPA-R01-OAR-2012-0950-0018"},{"title":"Temporary Permit (Permit No: TP-0008) for a Flue Gas Desulphurization System at Public Service of New Hampshire Merrimack Station, in Bow, NH Issued by the NH Department of Environmental Services, Air Resources Division.","document_id":"EPA-R01-OAR-2012-0950-0017"},{"title":"EPA Letter dated October 10, 2014 Approving New Hampshire Ambient Air Monitoring Program 2014/2015 Annual Network Review and Plan.","document_id":"EPA-R01-OAR-2012-0950-0016"},{"title":"New Hampshire Ambient Air Monitoring Program 2014/2015 Annual Network Review and Plan, dated July 2014.
