{"abstract":"The Environmental Protection Agency (EPA) is amending a Federal Implementation Plan (FIP) that addresses regional haze for the first planning period for Arkansas as it applies to the best available retrofit technology (BART) requirements for sulfur dioxide (SO<INF>2</INF>) and particulate matter (PM) for seven electric generating units (EGUs) in Arkansas and the SO<INF>2</INF> requirements under the reasonable progress provisions. These portions of the FIP will be replaced by the portions of a revision to the Arkansas State Implementation Plan (SIP) that we are taking final action to approve in a separate rulemaking that is published elsewhere in this issue of the Federal Register.","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/2019/09/27/2019-19877.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"84 FR 51056","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective October 28, 2019.","disposition_notes":null,"docket_ids":["EPA-R06-OAR-2015-0189","FRL-9997-88-Region 6"],"dockets":[],"document_number":"2019-19877","effective_on":"2019-10-28","end_page":51060,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/09/27/2019-19877.xml","html_url":"https://www.federalregister.gov/documents/2019/09/27/2019-19877/promulgation-of-air-quality-implementation-plans-state-of-arkansas-regional-haze-federal","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-19877?publication_date=2019-09-27","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-09-27/2019-19877/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":166,"last_updated":"2026-09-21 14:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-09-27/pdf/2019-19877.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-19877.pdf?1569501915","publication_date":"2019-09-27","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/09/27/2019-19877.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"AR020.0276-000 NPCA, Sierra Club, and Earth Justice Comments and PDF exhibits","document_id":"EPA-R06-OAR-2015-0189-0276"},{"title":"AR020.0271-000 SIP Appendix D","document_id":"EPA-R06-OAR-2015-0189-0271"},{"title":"AR020.0269-000 SIP Appendix B","document_id":"EPA-R06-OAR-2015-0189-0269"},{"title":"AR020.0243 Entergy Petition Seeking Reconsideration and Request for Administrative Stay of the Arkansas Regional Haze FIP. 306 pages 7.4 MB x7d","document_id":"EPA-R06-OAR-2015-0189-0243"},{"title":"AR020.0233 TCEQ_CAMx_Modeling_Guidance_2007Dec","document_id":"EPA-R06-OAR-2015-0189-0233"},{"title":"AR020.0230 reasonable_progress_guid071307","document_id":"EPA-R06-OAR-2015-0189-0230"},{"title":"AR020.0227 IWAQM phase 1","document_id":"EPA-R06-OAR-2015-0189-0227"},{"title":"AR020.0225 final-03-pm-rh-guidance_2007","document_id":"EPA-R06-OAR-2015-0189-0225"},{"title":"AR020.0224 Exhibit 7- Evaluation of Craig BART Modeling for Regional Haze Analysis- Hoffnagle","document_id":"EPA-R06-OAR-2015-0189-0224"},{"title":"AR020.0222 EPA RTC analysis_Craig Station","document_id":"EPA-R06-OAR-2015-0189-0222"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R06-OAR-2015-0189","supporting_documents_count":233,"docket_id":"EPA-R06-OAR-2015-0189","regulation_id_number":null,"title":"AR020 State of Arkansas; Regional Haze and Interstate Visibility Transport Federal Implementation Plan","checked_regulationsdotgov_at":"2019-09-30T03:30:08Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":51056,"subtype":null,"title":"Promulgation of Air Quality Implementation Plans; State of Arkansas; Regional Haze Federal Implementation Plan Revisions; Withdrawal of Portions of the Federal Implementation Plan","toc_doc":"Arkansas; Regional Haze Federal Implementation Plan Revisions; Withdrawal of Portions of the Federal Implementation Plan","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Ozone","Particulate matter","Reporting and recordkeeping requirements"],"type":"Rule","volume":84}
