{"abstract":"The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts. This SIP revision increases the total number of commercial parking spaces allowed in the Logan Airport Parking Freeze area by 5,000 parking spaces. The intended effect of this action is to reduce carbon monoxide (CO) and nitrogen oxide (NO<INF>X</INF>) emissions by reducing the increased vehicle miles traveled (VMT) resulting from insufficient available parking at Logan Airport. This action is being taken under the Clean Air Act.","action":"Final 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/2018/03/06/2018-04488.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"83 FR 9438","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on April 5, 2018.","disposition_notes":null,"docket_ids":["EPA-R01-OAR-2017-0590","FRL-9974-96-Region 1"],"dockets":[],"document_number":"2018-04488","effective_on":"2018-04-05","end_page":9440,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2018/03/06/2018-04488.xml","html_url":"https://www.federalregister.gov/documents/2018/03/06/2018-04488/air-plan-approval-massachusetts-logan-airport-parking-freeze","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2018-04488?publication_date=2018-03-06","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2018-03-06/2018-04488/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":281,"last_updated":"2026-06-24 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2018-03-06/pdf/2018-04488.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2018-04488.pdf?1520265620","publication_date":"2018-03-06","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2018/03/06/2018-04488.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Response to Comments Logan Parking Freeze 6-30-17","document_id":"EPA-R01-OAR-2017-0590-0009"},{"title":"Official Regulations Logan Parking Freeze 6-30-17","document_id":"EPA-R01-OAR-2017-0590-0008"},{"title":"Notice of Hearing Logan Parking Freeze","document_id":"EPA-R01-OAR-2017-0590-0007"},{"title":"Mass Register Frontal Material Logan Parking Freeze 6-30-17","document_id":"EPA-R01-OAR-2017-0590-0006"},{"title":"Logan Parking Freeze Background Document Attach 1 Technical Analysis","document_id":"EPA-R01-OAR-2017-0590-0005"},{"title":"Logan Parking Freeze Background Document 3-24-17","document_id":"EPA-R01-OAR-2017-0590-0004"},{"title":"Hearing Cerification Logan Airport Parking Freeze","document_id":"EPA-R01-OAR-2017-0590-0003"},{"title":"Cover Letter SIP Logan Parking Freeze 7-13-17","document_id":"EPA-R01-OAR-2017-0590-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R01-OAR-2017-0590","supporting_documents_count":8,"docket_id":"EPA-R01-OAR-2017-0590","regulation_id_number":null,"title":"Air Plan Approval; Massachusetts; Logan Airport Parking Freeze","checked_regulationsdotgov_at":"2018-03-26T10:00:15Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":9438,"subtype":null,"title":"Air Plan Approval; Massachusetts; Logan Airport Parking Freeze","toc_doc":"Massachusetts; Logan Airport Parking Freeze","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations:","topics":["Air pollution control","Carbon monoxide","Environmental protection","Incorporation by reference","Intergovernmental relations","Lead","Nitrogen dioxide","Ozone","Particulate matter","Reporting and recordkeeping requirements","Sulfur oxides","Volatile organic compounds"],"type":"Rule","volume":83}
