About Our Courses

The National Stormwater Center’s courses focus on stormwater inspectors, NPDES permit compliance, and intent of the regulations. We believe that permit compliance is the key to achieving the goals of the Clean Water Act, and that inspectors make the difference. Our courses are developed by former Federal and State enforcement officers to create stormwater inspectors who are knowledgeable and who possess the necessary skills and demeanor to be effective in their duties.

We offer a variety of courses, on location and via webinar, all of which are instructor-led.  The following links provide detailed information about certified stormwater inspector courses, MS4 (municipal) workshops, and industrial employee courses.
