{"abstract":"The Environmental Protection Agency (EPA) is proposing to determine that the San Joaquin Valley, California fine particulate matter (PM<INF>2.5</INF>) nonattainment area attained the 1997 annual PM<INF>2.5</INF> national ambient air quality standards (NAAQS) by the December 31, 2024 applicable attainment date. This proposed determination is based on ambient air quality monitoring data from 2022 through 2024. We are also proposing to make a clean data determination (CDD) based on the 2022 through 2024 data and our evaluation of preliminary air quality monitoring data from 2025. 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/2025/07/16/2025-13339.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"90 FR 31906","comment_url":null,"comments_close_on":"2025-08-15","correction_of":null,"corrections":[],"dates":"Comments must be received on or before August 15, 2025.","disposition_notes":null,"docket_ids":["EPA-R09-OAR-2025-0292","FRL-12825-01-R9"],"dockets":[{"supporting_documents":[{"title":"SJV 1997 Annual PM2.5 DAAD_Final_Docket Index","document_id":"EPA-R09-OAR-2025-0292-0034"},{"title":"F-1_91 FR 3836_SJV 1997 annual PM2.5 DAAD_2026-01-29","document_id":"EPA-R09-OAR-2025-0292-0033"},{"title":"E-2_AMP480_2025_2344358","document_id":"EPA-R09-OAR-2025-0292-0032"},{"title":"E-1_AMP480_2024_2335768","document_id":"EPA-R09-OAR-2025-0292-0031"},{"title":"D-2_SJV_Comment Letter for DAAD and CDD for the 1997 Annual PM2.5 Standard","document_id":"EPA-R09-OAR-2025-0292-0030"},{"title":"D-1_2025-08-05_Anonymous Comment","document_id":"EPA-R09-OAR-2025-0292-0029"},{"title":"SJV 1997 Annual PM2.5 DAAD_Proposal_Docket Index","document_id":"EPA-R09-OAR-2025-0292-0025"},{"title":"C-1_90 FR 31906_SJV 1997 annual PM2.5 DAAD CDD_2025-07-16","document_id":"EPA-R09-OAR-2025-0292-0024"},{"title":"B-3_2025-04-18 2024 Ltr - 2025 CARB Data Certification w encl","document_id":"EPA-R09-OAR-2025-0292-0023"},{"title":"B-2_2025-03-20 Ltr - 2024 SJV Data Certification w encl","document_id":"EPA-R09-OAR-2025-0292-0022"}],"agency_name":"EPA","documents":[{"comment_count":2,"comment_start_date":"2025-07-17","updated_at":"2025-08-19T01:55:53.986-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-R09-OAR-2025-0292-0001","allow_late_comments":false,"id":"EPA-R09-OAR-2025-0292-0001","comment_end_date":"2025-08-16","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":30,"id":"EPA-R09-OAR-2025-0292","title":"Determination of Attainment by the Attainment Date and Clean Data Determination;
