The Washington State University Pullman campus is covered by an Eastern WA Phase II Municipal Stormwater Permit issued by the WA State Department of Ecology.

Stormwater is generated when precipitation lands on impervious surfaces (roads, parking lots, rooftops and other hard impervious surfaces), and is subsequently discharged directly into local surface waters. Contaminates that may be present, such as vehicle fluids, pet waste, metals, litter and other substances are then washed into these local surface waters.

The Permit requires WSU Pullman to develop a Stormwater Management Program (SWMP) that minimizes the amount of contaminates that enter our local surface waters, and additionally requires that the SWMP be made available for public review and comment.
