{"abstract":"The U.S. Environmental Protection Agency (EPA) is proposing to amend the General Provisions for National Emission Standards for Hazardous Air Pollutants (NESHAP) to address applicability and compliance issues resulting from the addition of a compound to the list of hazardous air pollutants (HAP) under the Clean Air Act (CAA). This action focuses on issues related to newly applicable standards for sources that become major sources solely from the addition of a compound to the CAA HAP list. This action also includes a discussion of the impacts of a newly listed HAP on the federal operating permit program.","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/2023/09/13/2023-19674.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"88 FR 62711","comment_url":null,"comments_close_on":"2023-11-13","correction_of":null,"corrections":[],"dates":"Comments: Comments must be received on or before November 13, 2023.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2022-0441","FRL-8673-02-OAR"],"dockets":[{"supporting_documents":[{"title":"Proposed changes for 40 CFR Part 63 Subparts A and C","document_id":"EPA-HQ-OAR-2022-0441-0008"},{"title":"Combined RLSO document from OMB revew","document_id":"EPA-HQ-OAR-2022-0441-0007"},{"title":"2021-07-26 APF Comments on EPA ANPRM on 1-BP Listing  (as filed)","document_id":"EPA-HQ-OAR-2022-0441-0006"},{"title":"A2C Comments on 1-BP ANPR July 26 2021","document_id":"EPA-HQ-OAR-2022-0441-0005"},{"title":"1-BP HAP ANPRM - Advocacy Comment Letter - 2021.07.26  Final","document_id":"EPA-HQ-OAR-2022-0441-0004"},{"title":"Earth Justice-ANPRM comments","document_id":"EPA-HQ-OAR-2022-0441-0003"},{"title":"Comment from Dmachay at SCL Web","document_id":"EPA-HQ-OAR-2022-0441-0002"}],"agency_name":"EPA","documents":[{"comment_count":14,"comment_start_date":"2023-09-13","updated_at":"2023-12-12T00:01:43.275-05:00","comment_url":"https://www.regulations.gov/commenton/EPA-HQ-OAR-2022-0441-0001","allow_late_comments":null,"id":"EPA-HQ-OAR-2022-0441-0001","comment_end_date":"2023-11-14","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":7,"id":"EPA-HQ-OAR-2022-0441","title":"Regulatory Infrastructure for New HAP Additions to Part 63;
