{"abstract":"The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Defense (DoD) are promulgating discharge performance standards for 11 discharges incidental to the normal operation of a vessel of the Armed Forces in the navigable waters of the United States, the territorial seas, and the contiguous zone. When implemented, the discharge performance standards will reduce the adverse environmental impacts associated with the vessel discharges, stimulate the development of improved vessel pollution control devices, and advance the development of environmentally sound vessels of the Armed Forces. The 11 discharges addressed by the final rule include the following: Catapult water brake tank and post-launch retraction exhaust, controllable pitch propeller hydraulic fluid, deck runoff, firemain systems, graywater, hull coating leachate, motor gasoline and compensating discharge, sonar dome discharge, submarine bilgewater, surface vessel bilgewater/oil-water separator effluent, and underwater ship husbandry.","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"},{"raw_name":"DEPARTMENT OF DEFENSE","name":"Defense Department","id":103,"url":"https://www.federalregister.gov/agencies/defense-department","json_url":"https://www.federalregister.gov/api/v1/agencies/103","parent_id":null,"slug":"defense-department"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2020/07/17/2020-12571.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"1700","title":40}],"citation":"85 FR 43465","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on August 17, 2020.","disposition_notes":null,"docket_ids":["EPA-HQ-OW-2016-0351","FRL-10009-46-OW"],"dockets":[],"document_number":"2020-12571","effective_on":"2020-08-17","end_page":43478,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2020/07/17/2020-12571.xml","html_url":"https://www.federalregister.gov/documents/2020/07/17/2020-12571/uniform-national-discharge-standards-for-vessels-of-the-armed-forces-phase-ii-batch-two","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2020-12571?publication_date=2020-07-17","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2020-07-17/2020-12571/mods.xml","not_received_for_publication":null,"page_length":14,"page_views":{"count":2062,"last_updated":"2026-07-26 04:15:02 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2020-07-17/pdf/2020-12571.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2020-12571.pdf?1594903515","publication_date":"2020-07-17","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2020/07/17/2020-12571.txt","regulation_id_number_info":{"2040-AF53":{"issue":"202004","html_url":"https://www.federalregister.gov/regulations/2040-AF53/uniform-national-discharge-standards-for-vessels-of-the-armed-forces-phase-ii-batch-two-unds-","title":"Uniform National Discharge Standards for Vessels of the Armed Forces--Phase II - Batch Two (UNDS)","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202004&RIN=2040-AF53&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2040-AF53"],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":0,"agency_id":"DOD","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=DOD-2020-OS-0002","supporting_documents_count":0,"docket_id":"DOD-2020-OS-0002","document_id":"DOD-2020-OS-0002-0018","regulation_id_number":null,"title":"2020 documents NOT taking public comment","checked_regulationsdotgov_at":"2020-08-12T08:30:08Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":43465,"subtype":null,"title":"Uniform National Discharge Standards for Vessels of the Armed Forces-Phase II Batch Two","toc_doc":"Uniform National Discharge Standards for Vessels of the Armed ForcesPhase II Batch Two","toc_subject":null,"topics":["Armed forces","Coastal zone","Environmental protection","Reporting and recordkeeping requirements","Vessels","Water pollution control"],"type":"Rule","volume":85}
