EPA’s Transportation Stormwater Permit (MS4) Compendium

February 3 @ 2:00 pm - 3:00 pm

Stormwater discharges from roadways, including those within defined urbanized areas, are often covered under the NPDES Municipal Separate Storm Sewer System (MS4) regulations. State Departments of Transportation (DOTs) may be co-permittees with Phase I MS4s under a Phase I permit or small MS4s under either an individual or general Phase II MS4 permit. These permits typically include requirements related to pollution prevention, public education, public involvement, construction, post-construction for new development and redevelopment, and illicit discharge detection and elimination. Transportation stormwater management differs from traditional MS4 stormwater management in several ways, so transportation MS4 permit requirements are sometimes written differently.

This webinar will discuss EPA’s “Transportation Stormwater Permit Compendium,” a compendium of excerpted permit language from MS4 permits and other resources that can be used and/or tailored for transportation-specific MS4 permits. The webinar will discuss characteristics specific to transportation MS4s and roadway runoff, and will provide example excerpts of State DOT MS4 permits addressing various aspects of stormwater management for linear infrastructure projects.
