The MS4 Permit refers to The CT Stormwater Quality Manual
in several places. The manual was published by DEEP in 2004
and amended in 2011.
- Towns must require contractors, developers, and construction site operators to maintain consistency with the manual
- The use of low impact development must meet or exceed the practiices and standards laid out in the manual
- Disconnections of impervious cover from the stormwater system must be designed, installed, and contained consistent with the manual
Online Stormwater Quality Manual
NEMO is developing an interactive, searchable, online version of the Connecticut Stormwater Quality Manual that will be posted here in the fall of 2017. In the meantime, the pdf version of the manual, its worksheet, and the 2011 LID amendment can be viewed or downloaded below.
