The updated MS4 general permit requires municipalities to pass several 'legal authorities' which could be ordinances, bylaws, regulations, standard conditions of approval or other appropriate legal authorities. Generally, the three legal authorities in the permit are: to prohibit and eliminate illicit discharges, to require low impact development be considered before other practices for managing stormwater runoff, and to require and inspect stormwater runoff control practices at construction sites.
The examples we provide below don't substitute for real legal advice! Please be sure to consult your legal experts or town attorney.
In the Construction Site Stormwater Management (MCM 4) section of the CT MS4 Permit there is a requirement for MS4 communities to establish a legal authority to require certain measures to protect water quality during construction projects. We compiled example regulatory lanugage that can be adapted by MS4 communities to meet this legal authority requirement.
