An operational Best Management Practice (BMP) uses preventative actions that involve operational planning and source controls.

	Employee Training - MDOT teaches their employees about storm water management, potential pollution sources, and BMPs.
	Identify and Prohibit Illegal or Illicit Discharges to Storm Drains - Inventory of outfalls, field investigations and follow-up visits for suspected problems within the storm drains are some of the steps MDOT undertakes to pin point sources and implement corrective actions.
	Clean and Maintain Storm Inlets, Catch Basins and Drain Channels - Inlets, catch basins and manholes are periodically inspected and cleaned out using a vacuum truck.
	Street Sweeping - Removes sediment on roads and reduces the amount of pollutants entering local waters.
