{"abstract":"EPA is approving a revision to the New Hampshire State Implementation Plan (SIP) that addresses regional haze for the first planning period from 2008 through 2018. The revision was submitted by the New Hampshire Department of Environmental Services (NHDES) on January 29, 2010, with supplemental submittals on January 14, 2011, and August 26, 2011. This revision addresses the requirements of the Clean Air Act (CAA) and EPA's rules that require States to prevent any future, and remedy any existing, manmade impairment of visibility in mandatory Class I Areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the \"regional haze program\").","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/2012/08/22/2012-20271.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"77 FR 50602","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: This rule is effective on September 21, 2012.","disposition_notes":null,"docket_ids":["EPA-R01-OAR-2008-0599","A-1-FRL-9716-7"],"dockets":[],"document_number":"2012-20271","effective_on":"2012-09-21","end_page":50608,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/08/22/2012-20271.xml","html_url":"https://www.federalregister.gov/documents/2012/08/22/2012-20271/approval-and-promulgation-of-air-quality-implementation-plans-new-hampshire-regional-haze","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-20271?publication_date=2012-08-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-08-22/2012-20271/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":191,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-08-22/pdf/2012-20271.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-20271.pdf?1345553298","publication_date":"2012-08-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/08/22/2012-20271.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Comment Received on New Hampshire Regional Haze SIP","document_id":"EPA-R01-OAR-2008-0599-0084"},{"title":"New Hampshire Regional Haze SIP - NH DES's Response.","document_id":"EPA-R01-OAR-2008-0599-0083"},{"title":"New Hampshire Regional Haze SIP- Transmittal of NH DES's Response.","document_id":"EPA-R01-OAR-2008-0599-0082"},{"title":"New Hampshire Regional Haze SIP - Revised New Hampshire BART Modeling.","document_id":"EPA-R01-OAR-2008-0599-0081"},{"title":"New Hampshire Regional Haze 8-26-2011 Final.","document_id":"EPA-R01-OAR-2008-0599-0077"},{"title":"New Hampshire Regional Haze 8-26-2011 Final - redline.","document_id":"EPA-R01-OAR-2008-0599-0076"},{"title":"January 14, 2011 Supplemental SIP - Response to Sierra Club Comments 01-14-11","document_id":"EPA-R01-OAR-2008-0599-0075"},{"title":"January 14, 2011 Supplemental SIP - Response to FLMs Comments 01-14-11","document_id":"EPA-R01-OAR-2008-0599-0074"},{"title":"January 14, 2011 Supplemental SIP - Response to EPA Comments 12-09-10","document_id":"EPA-R01-OAR-2008-0599-0073"},{"title":"January 14, 2011 Supplemental SIP - Response to EPA Comments 03-10-10","document_id":"EPA-R01-OAR-2008-0599-0072"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R01-OAR-2008-0599","supporting_documents_count":80,"docket_id":"EPA-R01-OAR-2008-0599","regulation_id_number":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; New Hampshire; Regional Haze State Implementation Plan to Meet the Requirements of 40 CFR 51.308.","checked_regulationsdotgov_at":"2012-09-11T08:07:51Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":50602,"subtype":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; New Hampshire; Regional Haze","toc_doc":"New Hampshire; Regional Haze","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}
