Moms, teachers, and boy scouts everywhere always warn you to be prepared. Well, they are right. Walden recently assisted a Long Island municipality prepare for a joint USEPA and NYSDEC inspection of its Municipal Separate Storm Sewer System (MS4) program. This municipality is not alone. The USEPA and NYSDEC are teaming up and inspecting many municipalities on Long Island for complying with the National and State Pollution Discharge Elimination System (NPDES and SPDES) permit requirements specifically relating to the Municipal Separate Storm Sewer Systems (MS4s). They are conducting audits and inspections to ensure municipalities are meeting their established Best Management Practices (BMPs) for each of the Minimum Control Measures (MCMs) that are a part of the MS4 program. Make sure you are completely up to date on your stormwater management program (SWMP), meeting all of your BMP’s, and with your knowledge of governmental alphabet soup to ensure a smooth inspection.
