tmdl mapCLEAR’s venerable, award-winning NEMO (Nonpoint Education for Municipal Officials) Program is embarking on a five-year program to assist Connecticut communities in complying with the state’s revised “General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems,” or the MS4 permit. Stormwater runoff is a major source of flooding, erosion and water pollution in Connecticut’s waterways, and is expected to become even more of a problem as climate change progresses.
After much negotiation between CT DEEP, Connecticut municipalities and the environmental community, the MS4 underwent a significant expansion and enhancement this July. Eight new towns have been brought into the program, making a total of 121 (almost ¾ of all the municipalities in the state), and for the first time most state and federal institutions are also included. And, while the program remains organized according to its six “Minimum Control Measures,” there are important new aspects and requirements involving monitoring, maintenance of town properties, and “disconnecting” impervious areas through Low Impact Development (LID).
In the current economic environment Connecticut communities are struggling with a host of needs, and navigating the various aspects of the MS4 will be a challenge. In recognition of this, CT DEEP is funding NEMO to develop and implement a multifaceted support program that includes outreach, technical assistance, web tools and other resources. To list just a few:
  • MS4 “Circuit Rider”: a NEMO Extension Educator dedicated to the MS4 support program will conduct workshops, trainings and consultations with towns.
  • MS4 website: a website far above and beyond the typical regulation website is being developed, as an authoritative and detailed (but not wordy!) guide to MS4 implementation and home for special technical and mapping tools.
  • Webinar series: CLEAR’s webinar series will spin off a special NEMO/MS4 series highlighting different requirements of the regulation and approaches to meet them.
  • Mapping training: CLEAR’s Geospatial Training Program will provide training and tools to help communities meet the new mapping requirements of the permit.
  • Impervious Cover data: NEMO is working with an outside contractor to obtain high resolution impervious cover data, which will be an enormous asset to conducting the drainage area and impervious area analyses required in the permit.

The CLEAR Water Team (aka NEMO Team) is looking forward to this challenge, and in the process developing a whole new generation of stormwater outreach tools and resources. NEMO will be working with DEEP, regional Councils of Government, and both public and private sector organizations to tackle this issue so important to the health and welfare of the citizens of Connecticut.

Look for an announcement of the website soon. In the meantime you can view the CT DEEP MS4 Fact Sheet online (s.uconn.edu/ms4). Questions should be directed to Dave Dickson (david.dickson@uconn.edu) or Mike Dietz (michael.dietz@uconn.edu).
