On November 16, 1990, the Federal Register included notice of the promulgation of the NPDES Phase I Municipal Separate Storm Sewer System (MS4) program making this a major day in the stormwater sector. Since this time, thousands of communities, along with qualifying institutions and other entities, have developed MS4 programs and implemented millions of stormwater control measures collectively to address urban runoff pollution. This webinar will bring together stormwater professionals to recognize and celebrate the 2025 National Stormwater Day Stormwater Champion, Neil Weinstein as well as to provide an overview of the newly established EPA Stormwater Centers of Excellence for Stormwater Infrastructure Technologies (CESITs), present information on the Washington State Stormwater Awareness Week, present updates on the National Municipal Stormwater Alliance (NMSA), and share initial data findings from the recent Water Environment Federation (WEF) MS4 Needs Assessment Survey. This event is led by the National Municipal Stormwater Alliance (NMSA).
