CAUSE DESCRIPTION AND CORRECTIVE ACTION: (CONTINdED) j At 0020 while performing a rinse after regenerating the resin of #12 make-up train the Service Building Operator discovered #12 Waste Neutralizing Tank (WNT) level indication was pegged high; he immediately secured the rinse.
- Subsequent investigation revealed the WNT to be full and overflowing to the ground, resulting in an unmonitored discharge of the tank, which is not allowed .
by Environmental Tech Spec 2.2.1. A sam to 12.1 and total dissolved solids (TDS)ple equal totaken ofppm.
12,000 the tank showed a pH equal .l A calculation -
based on ititial tank level and flow to the tank revealed the quantity of regenerant ;
waste and rinse water that spilled on the ground to be approximately 8,400 gallons. j No environmental impact is expected since a rinse cycle was in progress resulting in dilution of the tank contents. The spilled regenerant waste was further I diluted by the flow in outfall 002, thus significantly minimizing any environmental !
impact associated with this event. !
