Waterbury FAQ

Any non-stormwater substance entering the storm drain system, including paint, oil, chemicals, or sediment. Report violations to Waterbury public works.
West Haven FAQ

Projects disturbing less than one acre typically do not need the state Construction General Permit, but local erosion control approval is still required and best management practices apply under municipal ordinances.

No. Connecticut municipalities must implement at least the minimum control measures required by the MS4 general permit. Local rules may be stricter but never less protective than state standards.
