The NPDES Training Institute developed the Municipal Separate Storm Sewer System Compliance & Enforcement Certified Inspector (MS4 CECI) course to fill a need for municipalities, SWPPP design professionals and regulatory plan reviewers to be properly educated and knowledgeable of their compliance and enforcement activities as MS4 operators. We’ve received scores of questions asking if we could provide an MS4 Inspector course for their people. As a result, we’ve invested a lot of time and energy into the MS4 CECI course that answers all the questions we’ve ever received about the MS4 program.

Luke Owen, Principal trainer and consultant for the NPDES Stormwater Training Institute, lead the development of the MS4 CECI course and invited federal, state and local government officials and consultants to review and edit the class modules. As a result, we believe the MS4 CECI course is by far the most effective course offered anywhere that truly helps the MS4 inspector fulfill his/her MS4 responsibilities in the field. The course explains the complexities of the MS4 program and how the permit ties into the overall NPDES construction & multi-sector general permit programs. Additionally, it gives specific guidance on how to perform MS4 outfall, IDDE investigations, facility inspections and outfall monitoring duties.

MS4 field compliance and enforcement inspectors (MS4 CECI’s) are where the rubber meets the road when it comes to effectively growing our economy and protecting our water resources at the same time. Without knowledgeable MS4 inspector oversight of our watersheds; local fishing holes have little hope of holding fish for the next generation.
