{"abstract":"Pursuant to the National Environmental Policy Act (NEPA) and Presidential Executive Order 12114, DoN has prepared and filed with the U.S. Environmental Protection Agency a Draft Supplemental Environmental Impact Statement/Overseas Environmental Impact Statement (SEIS/OEIS) for Surveillance Towed Array Sensor System Low-Frequency Active (SURTASS LFA) Sonar Training and Testing in the Western North Pacific and Indian Oceans. The Draft SEIS/OEIS includes an analysis of the potential environmental impacts associated with conducting at-sea training and testing activities within the SURTASS LFA Study Area. The purpose of the Proposed Action is to perform training and testing activities that ensure the Navy remains proficient in the use of SURTASS LFA sonar in support of the Navy's mission.","action":"Notice.","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 Navy","name":"Navy Department","id":378,"url":"https://www.federalregister.gov/agencies/navy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/378","parent_id":103,"slug":"navy-department"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2025/06/13/2025-10454.html","cfr_references":[],"citation":"90 FR 25038","comment_url":null,"comments_close_on":"2025-07-28","correction_of":null,"corrections":[],"dates":"The 45-day public comment period begins June 13, 2025 and ends July 28, 2025.
