Cause of Incident i

Approximately 100 gallons of 2000 ppm boron solution overflowed into a yard drain.

Date and Time The incident occurred on Saturday, August 30, 1986 at 12:30 pm. The duration was approximately 50 minutes.

t s; ,

e Summary The return line was connected to an ice machine from the roof of the auxiliary building to the storage tank on the ground. The line became disconnected from the tank and fell outside the secondary containment curbing which surrounds the tank. Absorbent material was placed around the yard drain to prevent as much as possible from being released while the line was being reconnected to the tank. The pH of this solution is 9.2 SU. The intake cove was thoroughly investigated and no visible impact was observed.

If you have any questions, please contact R.T. Simril at (704) 373-2310 or T.R. Story at (704) 373-7016.
