BOISE – The Idaho Department of Environmental Quality today issued a modified Idaho Pollutant Discharge Elimination System (IPDES) permit for the University of Idaho.
This action authorizes the university to discharge from all municipal separate storm sewer system (MS4) outfalls listed in the IPDES permit, including Paradise Creek and other associated waters of the United States.
The university requested a modification to the existing IPDES permit to incorporate alternative controls measures (ACMs), including combining screening of dry weather flows for multiple individual locations to one central location and using a computer-aided design map in place of the required Geographic Information System map.
On May 20, 2024, DEQ approved the ACMs as equivalent to the required Stormwater Management Program control measure, as authorized under the “Rules Regulating the Idaho Pollutant Discharge Elimination System Program” (IDAPA 58.01.25.201.02.c.ii.).
The final IPDES permit and fact sheet can be found on DEQ’s Issued Permits web page.
