Stormwater Management Program (SWMP)

The City of Pullman has been managing stormwater for a long time. However, to be more effective and create a successful program enhanced coordination between the various staff and departments that deal with stormwater needs to occur. The NPDES Phase II permit requires the City of Pullman to develop a comprehensive Stormwater Management Program (SWMP) and implement the Program prior to the end of the current permit cycle. A written report (SWMP) documenting the actions the City plans to implement to satisfy State requirements and protect water quality is required to be made available to Ecology annually  by March 31 and to the public by May 31.  It is the Stormwater Services policy to have a defined comment period on the Stormwater Management Plan. The comment period is from 3/31 to 5/15.
