Municipal Permit Assistance

The Municipal Permit Assistance program is a resource for NPDES Municipal Separate Stormwater System (MS4) Permit holders statewide. We provide stormwater management, education, outreach, and compliance assistance through a variety of services, products/projects, and activities.  This web page has links to those resources and provides a bridge between regulatory authorities and municipalities who must comply with the MS4 permits.
For assistance or more information about the Municipal Stormwater Program please contact:
