Description:
The WC (Conventional Waste Treatment System), Outfall 002, experienced a 9.4 pH level while discharging Settling Pond B.
This event occurred at 9:30 a.m. on February 2^.
1996.
Upon investigation, there appears to have been two problems tr..t led to the non-compliance: 1) The CO2 system
~
failed to perform as requL ed allowing the pH to exceed the limits and
- 2) the automatic shutoff valve that backs up the CO2 System was out of service for repairs and there were no additional fail-safe systems.
Settling Pond B was reading a pH of 8.6 on February 16, 1996 when discharge began.
After the elevated pH was detected, the discharge of Settling Pond B was discontinued.
Immediate repairs were initiated to correct the CO2 System and the automatic shutoff valve. After all repairs are completed and additional sampling performed, the discharge of Settling Pond B will continue.
