{"abstract":"The Environmental Protection Agency (EPA) is proposing to approve, through parallel processing, state implementation plan (SIP) revisions from the Yolo-Solano Air Quality Management District (YSAQMD or \"District\") to address Clean Air Act (CAA or \"Act\") requirements related to the 2008 8-hour ozone national ambient air quality standards (NAAQS or \"standards\"). These revisions concern emissions of oxides of nitrogen (NO<INF>X</INF>) from biomass boilers, and also address reasonably available control technology (RACT) requirements for major sources of NO<INF>X</INF> in the portion of the Sacramento Metro, CA, nonattainment area that is subject to YSAQMD jurisdiction. We are taking comments on this proposal and plan to follow with a final action.","action":"Proposed 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/2023/12/27/2023-28525.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"88 FR 89351","comment_url":null,"comments_close_on":"2024-01-26","correction_of":null,"corrections":[],"dates":"Comments must be received on or before January 26, 2024.","disposition_notes":null,"docket_ids":["EPA-R09-OAR-2023-0590","FRL-11615-01-R9"],"dockets":[{"supporting_documents":[{"title":"Section D - State Implementation Plan Submittal (February 14, 2024)","document_id":"EPA-R09-OAR-2023-0590-0006"},{"title":"Section C - EPA Guidance Documents","document_id":"EPA-R09-OAR-2023-0590-0005"},{"title":"Section B - Supporting Materials","document_id":"EPA-R09-OAR-2023-0590-0004"},{"title":"Section A - State Implementation Plan Submittal Documents","document_id":"EPA-R09-OAR-2023-0590-0003"},{"title":"Docket Index for Proposed Rule EPA-R09-OAR-2023-0590","document_id":"EPA-R09-OAR-2023-0590-0002"}],"agency_name":"EPA","documents":[{"comment_count":0,"comment_start_date":"2023-12-27","updated_at":"2024-01-27T00:04:28.520-05:00","comment_url":"https://www.regulations.gov/commenton/EPA-R09-OAR-2023-0590-0001","allow_late_comments":null,"id":"EPA-R09-OAR-2023-0590-0001","comment_end_date":"2024-01-27","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":5,"id":"EPA-R09-OAR-2023-0590","title":"Air Plan Revisions; California; Yolo-Solano Air Quality Management District"}],"document_number":"2023-28525","effective_on":null,"end_page":89355,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2023/12/27/2023-28525.xml","html_url":"https://www.federalregister.gov/documents/2023/12/27/2023-28525/air-plan-approval-california-yolo-solano-air-quality-management-district","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2023-28525?publication_date=2023-12-27","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2023-12-27/2023-28525/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":134,"last_updated":"2026-04-05 00:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2023-12-27/pdf/2023-28525.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2023-28525.pdf?1703598330","publication_date":"2023-12-27","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2023/12/27/2023-28525.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Section D - State Implementation Plan Submittal (February 14, 2024)","document_id":"EPA-R09-OAR-2023-0590-0006"},{"title":"Section C - EPA Guidance Documents","document_id":"EPA-R09-OAR-2023-0590-0005"},{"title":"Section B - Supporting Materials","document_id":"EPA-R09-OAR-2023-0590-0004"},{"title":"Section A - State Implementation Plan Submittal Documents","document_id":"EPA-R09-OAR-2023-0590-0003"},{"title":"Docket Index for Proposed Rule EPA-R09-OAR-2023-0590","document_id":"EPA-R09-OAR-2023-0590-0002"}],"comments_count":0,"agency_id":"EPA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R09-OAR-2023-0590","supporting_documents_count":5,"docket_id":"EPA-R09-OAR-2023-0590","document_id":"EPA-R09-OAR-2023-0590-0001","regulation_id_number":null,"title":"Air Plan Revisions; California; Yolo-Solano Air Quality Management District","checked_regulationsdotgov_at":"2024-01-27T05:04:27Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":89351,"subtype":null,"title":"Air Plan Approval; California; Yolo-Solano Air Quality Management District","toc_doc":"California; Yolo-Solano Air Quality Management District","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:\n","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Nitrogen oxides","Ozone","Reporting and recordkeeping requirements"],"type":"Proposed Rule","volume":88}
