Quotes
  • Ty Garmon (08:40): “Nobody cares about stormwater unless it’s coming in their house.”
  • Seth Brown (12:49): “We advocate as a 501c3 for our mission… to try to support MS4s… and make them more technically effective, more cost effective…”
  • Seth Brown (23:02): “we don’t want to have a bioretention facility become considered waters of the US.”
  • Seth Brown (47:xx): “can think of [STEP] as the consumer reports for stormwater infrastructure.”

In this episode of the Stormwater World Podcast, Ty Garmon talks with Dr. Seth Brown, Executive Director of NMSA, about why the alliance formed to give MS4 programs a unified national voice, how it advocates on issues like PFAS liability and Waters of the U.S., and the practical tools it offers members. They cover NMSA’s low-cost training and tracking, the open MS4 resource library, and membership options that fit both Phase I and Phase II communities. Seth explains National Stormwater Day on November 16 and how it recognizes the launch of the MS4 program while offering a free webinar and updates from Centers of Excellence. They dig into STEP, NMSA’s third-party testing effort meant to deliver clear, apples-to-apples performance data for proprietary BMPs. The episode closes with a call for stormwater to move from reactive work to proactive leadership and to claim its seat at the table.
