{"abstract":"The Environmental Protection Agency (EPA), Region 10, proposes to modify the National Pollutant Discharge Elimination System (NPDES) General Permit for Federal Aquaculture Facilities and Aquaculture Facilities Located in Indian Country in Washington (draft modified GP). The draft modified GP incorporates facility-specific conditions for Leavenworth National Fish Hatchery which will allow the facility to obtain coverage under the draft modified GP. Additionally, the draft modified GP proposes a modification to the chlorine monitoring requirements for all facilities covered under the GP. The draft modified GP and Fact Sheet addendum are available on the EPA Region 10 website at https://www.epa.gov/npdes-permits/npdes-general-permit- federal-aquaculture-facilities-and-aquaculture-facilities.","action":"Notice of proposed modification of NPDES General Permit and request for public comment.","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/2026/08/14/2026-16565.html","cfr_references":[],"citation":"91 FR 52688","comment_url":null,"comments_close_on":"2026-09-28","correction_of":null,"corrections":[],"dates":"Comments must be received by September 28, 2026.","disposition_notes":null,"docket_ids":["FRL-13413-01-R10"],"dockets":[{"supporting_documents":[{"title":"Adequacy Status of the Cleveland/Akron, Ohio and the Columbus, Ohio Submitted 8-Hour Ozone Redesignation and Maintenance Plans for Transportation Conformity Purposes","document_id":"EPA_FRDOC_0001-6733"},{"title":"DELETE","document_id":"EPA_FRDOC_0001-6642"},{"title":"Agency Information Collection Activities;
