{"abstract":"This rule establishes the initial air quality designations for most areas in the United States (U.S.), including Indian Country, for the 2006 24-hour fine particle (PM2.5) National Ambient Air Quality Standards (NAAQS). Through these designations, EPA is identifying areas that meet or violate these NAAQS. In particular, EPA is identifying the geographic boundaries of areas that violate, or contribute to violations of, the 2006 24-hour PM2.5 NAAQS. This is an important step toward providing the public health and welfare protections of the 2006 24-hour PM2.5 NAAQS. The Clean Air Act (CAA) requires states with areas designated nonattainment to undertake certain planning and pollution control activities within these areas in order to attain the standards as quickly as reasonably possible. Designating areas also helps citizens know whether the air quality where they live and work is healthful or unhealthful. Health studies have shown significant associations between exposure to PM2.5 and premature death from heart and lung disease. PM2.5 can also aggravate heart and lung diseases and has been linked to effects such as cardiovascular symptoms, cardiac arrhythmias, heart attacks, respiratory symptoms, asthma attacks, and bronchitis. These effects can result in increased hospital admissions, emergency room visits, absences from school or work, and restricted activity days. Individuals that may be particularly sensitive to PM2.5 exposure include people with heart or lung disease, older adults, and children.","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/2009/11/13/E9-25711.html","cfr_references":[{"chapter":null,"citation_url":null,"part":81,"title":40}],"citation":"74 FR 58688","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: The effective date of this rule is December 14, 2009.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2007-0562","FRL-8969-2"],"dockets":[],"document_number":"E9-25711","effective_on":"2009-12-14","end_page":58781,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2009/11/13/E9-25711.xml","html_url":"https://www.federalregister.gov/documents/2009/11/13/E9-25711/air-quality-designations-for-the-2006-24-hour-fine-particle-pm25-national-ambient-air-quality","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E9-25711?publication_date=2009-11-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2009-11-13/E9-25711/mods.xml","not_received_for_publication":null,"page_length":94,"page_views":{"count":581,"last_updated":"2024-03-30 04:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2009-11-13/pdf/E9-25711.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2009-11-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2009/11/13/E9-25711.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Email dated September 4, 2012 from Colleen McKaughan, USEPA Region 9 Associate Director Air Division, to Ginger Vagenas and Jefferson Wehling, USEPA Region 9, documenting conversation with Robert Palmquist, Ak-Chin Attorney, confirming that no additional ","document_id":"EPA-HQ-OAR-2007-0562-0574"},{"title":"Memorandum from Maeve Foley, USEPA Region 9 Grants & Program Integration Office to File regarding Communication with Brenda Ball about Potential Consultation with Ak-Chin Regarding 2006 24-hr PM2.5 Designation (August 21, 2012)","document_id":"EPA-HQ-OAR-2007-0562-0573"},{"title":"Memorandum from Colleen McKaughan, Associate Director, Air Division, Region 9 to File regarding Confirmation from Gila River Indian Community that Consultation Regarding 2006 24-hr PM2.5 Designation is Complete (August 21, 2012)","document_id":"EPA-HQ-OAR-2007-0562-0572"},{"title":"USEPA Air Quality System Preliminary Design Value Report and map titled 2009-2011 Design Values for the 2006 24-Hour Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards","document_id":"EPA-HQ-OAR-2007-0562-0571"},{"title":"Memorandum titled, Data Summary for Cowtown Monitor dated August 14, 2012, from Michael Flagg, USEPA Region 9 Air Quality Analysis Office, to Ginger Vagenas, USEPA Region 9 Air Planning Office","document_id":"EPA-HQ-OAR-2007-0562-0570"},{"title":"Memorandum to file regarding 110(k)(6) correction for the designation status for Ravalli, Montana, January 26, 2011","document_id":"EPA-HQ-OAR-2007-0562-0567"},{"title":"Designation decision letter from USEPA Administrator Jackson to Governor of California (CA), January 26, 2011","document_id":"EPA-HQ-OAR-2007-0562-0566"},{"title":"Summary Spreadsheet Data Dated October 28, 2009 Presenting PM2.5 Design Values Determined for the 3-year Periods from 2006-2008 -
