{"abstract":"The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submittal from the Alaska Department of Environmental Conservation (Alaska DEC) demonstrating that the SIP meets certain interstate transport requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated in 2010 for nitrogen dioxide (NO<INF>2</INF>) and sulfur dioxide (SO<INF>2</INF>). The EPA proposes to determine that Alaska's SIP contains adequate provisions to ensure that air emissions in Alaska do not significantly contribute to nonattainment or interfere with the maintenance of the 2010 NO<INF>2</INF> and SO<INF>2</INF> NAAQS in any other state.","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/2018/04/23/2018-08426.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"83 FR 17627","comment_url":null,"comments_close_on":"2018-05-23","correction_of":null,"corrections":[],"dates":"Comments must be received on or before May 23, 2018.","disposition_notes":null,"docket_ids":["EPA-R10-OAR-2016-0590","FRL-9977-06-Region 10"],"dockets":[{"supporting_documents":[{"title":"302 Supplemental Materials Memo to Docket 5 24 2018","document_id":"EPA-R10-OAR-2016-0590-0013"},{"title":"006_state submittals_Response to Comments","document_id":"EPA-R10-OAR-2016-0590-0007"},{"title":"005_state submittals_Public Notice","document_id":"EPA-R10-OAR-2016-0590-0006"},{"title":"004_state submittals_EPA Transmittal Letter","document_id":"EPA-R10-OAR-2016-0590-0005"},{"title":"003_state submittals_Affadavits","document_id":"EPA-R10-OAR-2016-0590-0004"},{"title":"002_state submittals_Adoption Memo","document_id":"EPA-R10-OAR-2016-0590-0003"},{"title":"001_state submittals_Interstate Transport","document_id":"EPA-R10-OAR-2016-0590-0002"}],"agency_name":"EPA","documents":[{"comment_count":4,"comment_start_date":"2018-04-23","updated_at":"2023-03-01T01:43:26.513-05:00","comment_url":"https://www.regulations.gov/commenton/EPA-R10-OAR-2016-0590-0001","allow_late_comments":null,"id":"EPA-R10-OAR-2016-0590-0001","comment_end_date":"2018-05-24","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":7,"id":"EPA-R10-OAR-2016-0590","title":"Air Plan Approval;
