The State Water Control Board reissued, with amendments, the Virginia Pollutant Discharge Elimination System general permit for discharges of stormwater from construction activities. The amendments, among other things, update provisions concerning authorization of non-stormwater discharges, implement new requirements for controlling construction dewatering discharges to impaired waters or exceptional waters, and add a turbidity benchmark option to the contents of the stormwater pollution prevention plan.
