{"abstract":"The Environmental Protection Agency (EPA) and the Department of the Army (\"the agencies\") are finalizing a rule defining the scope of waters protected under the Clean Water Act. In developing this rule, the agencies considered the text of the relevant provisions of the Clean Water Act and the statute as a whole, the scientific record, relevant Supreme Court case law, and the agencies' experience and technical expertise after more than 45 years of implementing the longstanding pre-2015 regulations defining \"waters of the United States.\" This final rule advances the objective of the Clean Water Act and ensures critical protections for the nation's vital water resources, which support public health, environmental protection, agricultural activity, and economic growth across the United States.","action":"Final rule.","agencies":[{"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"},{"raw_name":"Department of the Army, Corps of Engineers","name":"Engineers Corps","id":142,"url":"https://www.federalregister.gov/agencies/engineers-corps","json_url":"https://www.federalregister.gov/api/v1/agencies/142","parent_id":103,"slug":"engineers-corps"},{"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/2023/01/18/2022-28595.html","cfr_references":[{"chapter":null,"citation_url":null,"part":328,"title":33},{"chapter":null,"citation_url":null,"part":120,"title":40}],"citation":"88 FR 3004","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This action is effective on March 20, 2023.","disposition_notes":null,"docket_ids":["EPA-HQ-OW-2021-0602","FRL-6027.4-01-OW"],"dockets":[{"supporting_documents":[],"agency_name":"COE","documents":[{"comment_count":null,"comment_start_date":null,"updated_at":"2023-02-25T06:03:24.604-05:00","comment_url":"https://www.regulations.gov/commenton/COE-2023-0001-0002","allow_late_comments":null,"id":"COE-2023-0001-0002","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"COE-2023-0001","title":"National Environmental Policy Act Notices and Other Notices"},{"supporting_documents":[{"title":"Summary Report of Tribal Consultation and Engagement for the Proposed Rule: Revised Definition of  Waters of the United States","document_id":"EPA-HQ-OW-2021-0602-0106"},{"title":"Multiflume runoff event August 1, 1990 (Video)","document_id":"EPA-HQ-OW-2021-0602-0104"},{"title":"68 FR 1995 (2003 SWANCC Guidance)","document_id":"EPA-HQ-OW-2021-0602-0095"},{"title":"United States v.
