    Passive Treatment System
    Rochester Mills
    Little Mahoning Creek - North Branch

    Discharge #1, the smaller of 3 discharges, is treated with an OLC, whose effluent precipitates metals into a large forested area before entering Cessna Run. Discharges #2 and #3 were captured and transported to the same treatment system, an OLD with two accompanying sedimentation ponds.
