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-vigilent in identifying and preventing illicit discharges.

Military / Federal facilities can also have MS4, Industrial, and Construction permits.  They have to follow the same rules, plus they must 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
  • Public Involvement and Participation
  • Illicit Discharge Detection and Elimination
  • Management of Construction Site Run-Off
  • Management of Post-Construction Site Run-Off
  • Good Housekeeping

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 7,333 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.
