{"abstract":"The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of revisions to the Maricopa County Air Quality Department (MCAQD or \"County\") portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOC) from loading of organic liquids and gasoline. We are proposing action on local rules to regulate these emission sources under the Clean Air Act (CAA or \"Act\"). We are also proposing to disapprove the MCAQD's reasonably available control technology (RACT) demonstration for the source categories associated with these rules for the 2008 8-hour ozone national ambient air quality standards (NAAQS) in the Phoenix-Mesa ozone nonattainment area. 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/2024/11/08/2024-25947.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"89 FR 88690","comment_url":null,"comments_close_on":"2024-12-09","correction_of":null,"corrections":[],"dates":"Comments must be received on or before December 9, 2024.","disposition_notes":null,"docket_ids":["EPA-R09-OAR-2024-0349","FRL-12130-01-R9"],"dockets":[{"supporting_documents":[{"title":"A-01 Technical Support Document Maricopa 352","document_id":"EPA-R09-OAR-2024-0349-0012"},{"title":"A-02 Technical Support Document Maricopa 353","document_id":"EPA-R09-OAR-2024-0349-0011"},{"title":"C-01Guidance Doc for Correcting Common VOC and Other Rule Deficiencies","document_id":"EPA-R09-OAR-2024-0349-0010"},{"title":"D-01 Maricopa Rule 352 353 CondApp TSD August 2019","document_id":"EPA-R09-OAR-2024-0349-0009"},{"title":"C-02 Issues Relating to VOC Regulation Cutpoints Deficiencies and Deviations (aka Bluebook)","document_id":"EPA-R09-OAR-2024-0349-0008"},{"title":"B-06 Rule 353 Staff report","document_id":"EPA-R09-OAR-2024-0349-0007"},{"title":"B-04 Rule 353 Clean copy","document_id":"EPA-R09-OAR-2024-0349-0006"},{"title":"B-03 Rule 352 Staff report","document_id":"EPA-R09-OAR-2024-0349-0005"},{"title":"B-02 Rule 352 Change copy","document_id":"EPA-R09-OAR-2024-0349-0004"},{"title":"B-01 Rule 352 Clean copy","document_id":"EPA-R09-OAR-2024-0349-0003"}],"agency_name":"EPA","documents":[{"comment_count":1,"comment_start_date":"2024-11-08","updated_at":"2024-12-10T00:05:27.698-05:00","comment_url":"https://www.regulations.gov/commenton/EPA-R09-OAR-2024-0349-0001","allow_late_comments":false,"id":"EPA-R09-OAR-2024-0349-0001","comment_end_date":"2024-12-10","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":11,"id":"EPA-R09-OAR-2024-0349","title":"Air Plan Revisions;
