MCM 3: Outfall Inspections
Permittees with NPDES Municipal Separate Storm Sewer System (MS4) permit coverage are required to conduct screening of their regulated MS4 outfalls as part of Minimum Control Measure 3 (MCM3), Illicit Discharge Detection and Elimination. This course was developed to provide learners with step-by-step guidance on how to conduct dry weather screenings of MS4 outfalls to evaluate for the presence of illicit discharges.
