Certified Municipal Stormwater Inspector

Municipalities have great responsibilities that they are required to administer under their NPDES MS4 permits. In addition to managing their own stormwater discharges and the six required Minimum Control Measures (MCMs), they must also inspect Construction and Industrial Permittee activities within their jurisdictions, and by municipal code, they also inspect commercial activities. They often need to form alliances and partnerships with neighboring municipalities and watershed districts, they need to inform and educate their citizens, and their field personnel need to be ever vigilant in identifying and preventing illicit discharges.

Military / Federal facilities can also have MS4, Industrial, and Construction permits.  They must follow the same rules, plus they have to comply with Section 432 of the 2007 Energy Independence and Security Act (EISA) which requires that post-construction hydrology not exceed pre-construction hydrology.  Throughout the year the National Stormwater Center will conduct CSI-MS4 classes that are specifically designed to include Military / Federal personnel.

The MS4 Stormwater Management Program (SWMP) details the procedures and processes municipalities will follow to stay in compliance with their NPDES permit. It must address the six Minimum Control Measures which are:

  • Public Education and Outreach                                         Good Housekeeping
  • Public Involvement and Participation                               Post Construction Site Run-Off
  • Illicit Discharge Detection and Elimination                      Construction Site Run-Off

MS4 permittees are required to implement the 6 MCMs, track and measure their effectiveness, and make corrections as needed.  Effective stormwater inspectors must understand their MS4 permit, as well as their regulatory authority's construction and industrial permits. Municipal Stormwater Inspectors implement and manage their municipality's SWMP as well as inspect construction sites, industrial sites, and by municipal ordinance, all commercial activity in their jurisdiction. Understanding their role, authority, and the demeanor Inspectors should display is critical to success, and to the implementation of the community's stormwater pollution prevention program.

Permits require "Qualified Personnel" conduct inspections and be part of the Stormwater Team.  National Stormwater Center certifies graduates.  This certification indicates that the services conducted are being performed by professionals who have met the established standards of knowledge, experience, and competence required in the field of stormwater inspections.  The National Stormwater Center's CSI-MS4 class has been an integral part of the success of more than 10,200 municipal inspectors across the country.  

During these times, our training classes are being conducted via instructor-led, interactive webinar technology. The National Stormwater Center cares about the health and safety of our customers and our staff and will continue to practice physical distancing measures until such time that in-person classes can safely be resumed.  Testing will be conducted; students are required to achieve a minimum overall score of 75% to be awarded 1.6 CEUs (Continuing Education Units), and a five (5) year Certified Municipal Stormwater Inspector certificate from the National Stormwater Center.

Municipal Personnel who take this course typically have responsibility for:

  • Inspections                                                                           Reporting & Signatory Certifications
  • Annual Reports                                                                    Illicit Discharge Detection & Elimination

Here are recent feedback comments:

"We had a great time – all of us. Everybody reported in afterwards and it was a hot topic in our group texts after it concluded. This is a large portion of what that group handles on a daily basis."

 "Class was great! I would recommend it to anyone or organization that has anything to do with drainage, construction, or water quality. Jeff is the perfect instructor for this class."

"I love your teaching style. Thank you so much for spending the extra time after the class to help me understand my permit. "

"I was able to learn a lot that I can bring back, and hopefully get the ball rolling here in my community."

"The class reaffirmed most of what I am doing and filled in the gaps to everything I wasn’t sure about."

"I was concerned about this being in webinar format, but I think Jeff did a good job of asking for participation from all of us. It definitely made me stay focused on the content – even though I just wanted to be outside enjoying the nice weather on Tuesday!"

"I can’t let the day end before thanking you. Like every National Stormwater Center class I’ve attended, masterfully prepared and delivered. And about as lively as the subject of environmental regulation could ever hope to get."


"Thank you for the engaging and informative class yesterday. I learned a lot, and now have an awareness of several shortcomings in our SWPPP and storm water plan."

"Very interesting material. I wish there was a way to implement it without impeding upon the profit incentive of all the business people of the world. I guess as the population on the earth increases, even doubling in the next 30 or so years, the need for clean water will become even more of a public incentive and it may become easier to get regulations in place that can help.
