Stormwater Permits
Stormwater is water from rain or snow that flows over surfaces such as parking lots, roofs, and sidewalks, picking up pollutants along the way. It flows untreated into a conveyance system, ultimately reaching the river. Idaho State University is a partner for the City of Pocatello Stormwater Permit.
Common stormwater pollutants include pet waste, litter, loose soil or dirt, and fertilizer, as well as pesticides and herbicides that are applied incorrectly. Stormwater pollutants aggregate as water flows overland.
The Pocatello Urbanized Area MS4 Permit defines an illicit discharge as “any discharge to an MS4 that is not composed entirely of stormwater." Section 2.4 of the MS4 Permit outlines allowable discharges. Any questions on allowable discharges should be directed to EHSS. Idaho State partners with the City of Pocatello for illicit discharge reporting.
If you see an illicit discharge on the Pocatello Campus, you may report it by:
- In the event of an emergency that is immediately dangerous to human health or the environment, dial 911
- Call EHS Director at (208) 282-3498 during normal business hours
- Call the City of Pocatello at (208) 234-6225
- Report to the City of Pocatello utilizing their online reporting form
