Stormwater Management Plan

Stormwater Management Plan

The Connecticut Department of Energy and Environmental Protection issued an updated "General Permit for the Discharge of Storm water from Small Municipal Separate Storm Sewer Systems"  (MS4 Permit) which took effect on July 1, 2017.  This permit regulates the discharge of storm water from all of the Town-owned and maintained drainage systems, and includes many new requirements related to such items as illicit discharge detection and elimination, water quality treatment for private developments that discharge into the town system, and increased inspection and maintenance requirements for public and private storm water infrastructure. A fact sheet describing the updated permit can be found here:  CT DEEP Fact Sheet

The Towns plan for compliance with this new permit is now available for review via this link:

Illicit Discharge Detection and Elimination (IDDE) Program

The DEEP MS4 General Permit also requires that the Town develop and implement a plan for the detection and elimination of illicit discharges to the town storm drainage system.  These may include continuous discharges such as cross connections of sanitary sewer pipes, as well as point source discharges such as septic system failures or sanitary sewer overflows.  The Town IDDE Program can be found using the link below.
