A Spill Kit Program Success Story


The MS4 permit holders in Washington have formed regional alliances to share permit compliance resources and information.  These regional permit coordination groups are a place to help each other with stormwater management requirements and allow mentoring and sharing information and materials among jurisdictions.  This collaborative approach saves valuable time and resources and provides for a greater positive impact on Washington’s waters. If you are a part of a stormwater coordinator group not listed below or have information you’d like to share with other stormwater professionals, please contact Laurie Larson-Pugh.
