DEQ seeks comment on proposed settlement action with City of Aberdeen 

Accepting comments from June 23, 2025, through July 23, 2025. 

The Idaho Department of Environmental Quality (DEQ) is seeking comment on a proposed settlement action and consent judgment with the City of Aberdeen for violations of the Clean Water Act and Idaho Pollutant Discharge Elimination System (IPDES) permit. The violations occurred at the city’s publicly owned wastewater treatment facility, which discharges into Little Hole Draw, a tributary to the American Falls Reservoir. 

The city obtained coverage under IPDES permit number ID0020176 as a discharger from its wastewater treatment facility at 2683 W. 1750 S. Aberdeen, Idaho. DEQ alleges that the city failed to comply with all applicable conditions of its permit. DEQ prepared a consent judgment directing Aberdeen to resolve the violations and pay an adjusted civil penalty of $26,525, with $21,220 administered as stipulated penalties, requiring the city to pay a total of $5,305 for the alleged violations. The city signed the consent judgment on April 8, 2025, and, in compliance with Idaho Code § 39-108(9) and the “Rules Regulating the Idaho Pollutant Discharge Elimination System Program” (IDAPA 58.01.25.500.04), DEQ is publishing the proposed settlement action for public comment. 

The proposed settlement action is available for public review on DEQ’s Public Comment Opportunities web page and at DEQ’s State Office (1410 North Hilton Street, Boise, Idaho 83706). Written comments will be accepted through July 23, 2025, at 5 p.m. MST. This settlement action may be amended or adjusted in the future, in which case, DEQ may provide an additional public comment opportunity.
