While washing a weak caustic storage tank to a recovery sump, the drain basin at the tank plugged with solids and overflowed to an adjacent storm runoff sewer which discharges downstream of our pH neutralization system. A change in operating procedures has been implemented to have the retention* gate in the storm sewer closed during washing out of area tanks. - (1 hr. 8 min.)-Misinterpretation of instructions i . regarding the clearing of a caustic product storage tanl for essential maintenance resulted in caustic reaching Outfall 001 downstream of the pH neutralization system.
