MS4 Pond Maintenance

General Information

The Municipal Separate Storm Sewer System (MS4) General Permit requires permitted agencies to inspect all ponds and outfalls (the point where storm water enters into a receiving water body) once every five years, or about 20% per year. The goal of the inspection is to determine whether a component is in good working condition and able to perform its intended function. Pond inspections are generally scheduled to begin in June.

See Before and After photos of pond outfalls.
