On March 24, 2023, a discharge occurred from Outfall 00D that was below the minimum pH permit limit of 6 . 5 . Approximately 39,000 gallons of water were discharged to the on-site absorption pond with a pH value between 3.5 and 6 . 0 . The next discharge, which also occurred on March 24, 2023, had a value of 9 .4 , which was within the proper pH l i m i t. Follow up samples of downgradient wells were taken and indicated within l i m i t pH values of 7 . 0 6 and 7 . 8 5 . C N P has not observed any environmental impact from this discharge. Corrective actions have been implemented to prevent reoccurrence.

Subject:
Donald C. Cook Nuclear Plant Groundwater Discharge Permit GW 1 8 l 0 I 02
Dear Ms. Klang,
By the above reference the Donald C. Cook Nuclear plant (CNP) provided notification of a pH noncompliance that occurred on March 24, 2023. This letter provides the written follow up notification of this event as required by the CNP Groundwater Discharge Permit ( G W I 8 1 0 1 02), Part I.I I d), Compliance Requirements. The lower pH limit for Outfall OOD (Turbine Room Sump) was exceeded during a pump-out on March 24, 2023. Approximately 39,000 gallons of pH range 3 . 5 6.0 was discharged to the on-site absorption pond.
As required by the CNP Groundwater Discharge Permit ( G Wl 8 10 1 0 2 ) , Part 1.11.c), the on-line pH meter data recorded a within limit pH value o f 9. 4 on March 24, 2023, at 22 : 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> during the next discharge period.
The following is a summary of an internal evaluation of the cause for the pH lower limit to be exceeded:
The Turbine Room Sump (Outfall 00D) effluent is continuously monitored by an on-line pH meter. Alarms are set for Low pH at 7.0, and High pH at 9.0. When the pH meter alarms, a signal is sent to a valve controller that will send a signal to the discharge valve to shut off the flow. An alarm is also sent to the control rooms, and subsequently the sump recirculation alarm light illuminates at the make-up plant panel.
On March 27, 2023, Turbine Room Sump pH data was downloaded for preparation of the monthly Discharge Monitoring report. It was noted that there was a period of time where the pH of the discharge was below the limit of 6.5, and during the following pump out the pH had returned to 9.4.
Cause investigation showed that both the calibration checks for the pH meter and the alarm function was satisfactory before and after the exceedance.
Interviews with operations personnel concluded the operator failed to verify that the discharge valve indicated closed before leaving the panel.
May 1 7 , 2023 OW Pennit G W 1 8 10 10 2 Page2 Follow up samples of downgradient wells were taken and indicate nonnal values.
Date Monitoring point pH Results 4/4/2023 Monitoring Well EW IA 7.06 4/4/2023 Monitoring Well E W I 2 7.85 We inspect the on-site absorption pond on a weekly basis and have not observed any environmental impact from this discharge. Based on the dilution of the effluent by a 6 million gallon settling pond, and additional groundwater dilution, there was no impact to the surrounding groundwater from this event. With this notification we have met Part 1. 1 la-d of the CNP Groundwater Discharge Pennit ( G W I 8 1 0 1 0 2 ) requirements.
The event was communicated to the Site to prevent a reoccurrence. A procedure change was initiated to clarify site and pennit compliance expectations during pH out of pennit compliance situations. Ongoing management observations are in place to detect any nonnalized behaviors that may have affected the event outcome.
