The CT Department of Energy and Environmental Protection (DEEP) issued a new General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4) on January 20, 2016. The permit applies to all NVCOG municipalities with the exception of Bethlehem, and represents a marked increase in municipal responsibility in the management of stormwater and stormwater infrastructure over the previous permit originally issued in 2004.
The new permit retains the original 6 Minimum Control Measures found in the previous permit, but prescribes more comprehensive compliance requirements. NVCOG staff has prepared this MS4 Detailed Comparison between the previous and new permits.
UConn’s Center for Land Use Education and Research (CLEAR) Nonpoint Education for Municipal Officials (NEMO) program has been contracted by DEEP to provide MS4 assistance and outreach to municipalities. They have developed the Connecticut MS4 Guide, an online resource that includes information, guidance, maps and tools to help municipalities work through the permit process. They have also developed a Stormwater Management Plan Template, a comprehensive interactive online map, and have a Municipal Stormwater Educator available to answer questions and provide assistance.
Assistance with Stormwater Management Plan Updates and MS4 Program Registration
In order to assist municipalities with initial MS4 requirements, NVCOG can provide a pre-qualified list of consultants that can provide assistance with required stormwater management plan updates and MS4 program registration. Please contact NVCOG Senior Regional Planner Aaron Burdis, email@example.com, for the list of pre-qualified consultants.
Public Outreach and Education
NVCOG has contracted with the Pomperaug River Watershed Coalition (PRWC) to provide public outreach materials through the RiverSmart program. By participating in the program, NVCOG municipalities were able to meet all outreach and education requirements of the previous MS4 General Permit. NVCOG is working with PRWC to expand the program to include the new requirements, and we hope to continue to provide public outreach and education support for the new permit through the RiverSmart program.
MS4 and LID Local Regulation Assessment
NVCOG staff conducted assessments of all local regulations in the context of the required legal authorities and regulatory changes required under the new permit. Changes to local regulations will likely be necessary specifically regarding three sections of the new MS4 permit: Illicit Discharge Detection and Elimination, Construction Site Stormwater Runoff Control, and Post Construction Stormwater Management. Detailed assessments have been provided to each NVCOG municipality along with suggestions to meet the permit requirements. Assessment reports and assistance available upon request. Please contact Aaron Budris, abudris@nvcogct.
NVCOG can provide mapping tools and assistance to municipalities for MS4 permit compliance. Please contact NVCOG GIS Coordinator Glenda Prentiss, firstname.lastname@example.org for details.
UConn CLEAR has developed a comprehensive interactive online map to assist with MS4 Registration and Stormwater Management Plans.
