{"abstract":"The Environmental Protection Agency (EPA) is promulgating a source-specific Federal Implementation Plan (FIP) requiring the Navajo Generating Station (NGS), a coal-fired power plant located on the Navajo Nation near Page, Arizona, to achieve reductions in oxides of nitrogen (NOX) required under the Best Available Retrofit Technology (BART) provisions of the Clean Air Act (CAA) and the Regional Haze Rule (RHR). On February 5, 2013, EPA issued a proposed BART determination for NGS and an alternative to BART. In a supplemental proposal on October 22, 2013, EPA proposed to approve a new alternative plan, based on an agreement developed by a group of stakeholders known as the Technical Work Group (TWG). EPA is finalizing the alternative to BART described in our supplemental proposal. This rule is consistent with the TWG Agreement, including a lifetime cap in total emissions of NOX from NGS over 2009-2044 (2009-2044 NOX Cap). Our final action will achieve greater emissions reductions than BART and is expected to significantly reduce the impact of NGS on visibility at 11 mandatory Class I Federal areas. The operator of NGS must implement one of several alternative operating scenarios to achieve the necessary emission reductions to comply with the 2009-2044 NOX Cap.","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/2014/08/08/2014-18228.html","cfr_references":[{"chapter":null,"citation_url":null,"part":49,"title":40}],"citation":"79 FR 46514","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective date: This rule is effective on October 7, 2014.","disposition_notes":null,"docket_ids":["EPA-R09-OAR-2013-0009","FRL-9914-62-Region 9"],"dockets":[],"document_number":"2014-18228","effective_on":"2014-10-07","end_page":46555,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2014/08/08/2014-18228.xml","html_url":"https://www.federalregister.gov/documents/2014/08/08/2014-18228/approval-of-air-quality-implementation-plans-navajo-nation-regional-haze-requirements-for-navajo","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2014-18228?publication_date=2014-08-08","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2014-08-08/2014-18228/mods.xml","not_received_for_publication":null,"page_length":42,"page_views":{"count":889,"last_updated":"2024-03-19 06:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2014-08-08/pdf/2014-18228.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2014-18228.pdf?1407415714","publication_date":"2014-08-08","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2014/08/08/2014-18228.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Adequacy Status of the Cleveland/Akron, Ohio and the Columbus, Ohio Submitted 8-Hour Ozone Redesignation and Maintenance Plans for Transportation Conformity Purposes","document_id":"EPA_FRDOC_0001-6733"},{"title":"DELETE","document_id":"EPA_FRDOC_0001-6642"},{"title":"Agency Information Collection Activities; Proposals, Submissions, and Approvals","document_id":"EPA_FRDOC_0001-6334"},{"title":"Literature Search for 2,3,7,8-Tetrachlorodibenzo-p-Dioxin(TCDD) Dose-Response Studies for Use in an Upcoming Expert Panel Workshop","document_id":"EPA_FRDOC_0001-6019"},{"title":"Regulatory Agenda Semiannual Regulatory Agenda","document_id":"EPA_FRDOC_0001-6015"},{"title":"Correction to MVEBs for the Indiana and Ohio Portions of the Cincinnati-Hamilton, Ohio/Kentucky/Indiana, Submitted 8-Hour Ozone Attainment Demonstration","document_id":"EPA_FRDOC_0001-5132"},{"title":"Pesticides; tolerances in food, animal feeds, and raw agricultural commodities: Pyriproxyfen","document_id":"EPA_FRDOC_0001-3649"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA_FRDOC_0001","supporting_documents_count":7,"docket_id":"EPA_FRDOC_0001","regulation_id_number":null,"title":"Recently Posted EPA Rules and Notices from FR Feed.","checked_regulationsdotgov_at":"2014-08-28T06:00:13Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":46514,"subtype":null,"title":"Approval of Air Quality Implementation Plans; Navajo Nation; Regional Haze Requirements for Navajo Generating Station","toc_doc":"Navajo Nation; Regional Haze Requirements for Navajo Generating Station","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Administrative practice and procedure","Air pollution control","Environmental protection","Indians","Intergovernmental relations","Reporting and recordkeeping requirements"],"type":"Rule","volume":79}
