| (a) NPDES Discharge Permit 02-DP-0 187, Calvert Cliffs Nuclear Power Plant On February 18, 2010, Calvert Cliffs Nuclear Power Plant (CCNPP) personnel identified that waste'water with a pH greater than 9.0 was discharged from the CCNPP site in Lusby, MD between December 18, 2009 and January 26, 2010. The water discharged exceeded the limits of Reference (a). The wastewater was predominantly leakage from the condensate system, consisting of high purity Water with less than 10 ppm of amines added. The pH of the waste water did not exceed 9.7 at any time.The cause of non-compliance was a misunderstanding by plant personnel. | | (a) NPDES Discharge Permit 02-DP-0 187, Calvert Cliffs Nuclear Power Plant On February 18, 2010, Calvert Cliffs Nuclear Power Plant (CCNPP) personnel identified that waste'water with a pH greater than 9.0 was discharged from the CCNPP site in Lusby, MD between December 18, 2009 and January 26, 2010.

SUBJECT:
Calvert Cliffs Nuclear Power Plant Special Report: Noncompliance with Effluent Limitations
REFERENCE:
(a) NPDES Discharge Permit 02-DP-0 187, Calvert Cliffs Nuclear Power Plant On February 18, 2010, Calvert Cliffs Nuclear Power Plant (CCNPP) personnel identified that waste'water with a pH greater than 9.0 was discharged from the CCNPP site in Lusby, MD between December 18, 2009 and January 26, 2010. The water discharged exceeded the limits of Reference (a). The wastewater was predominantly leakage from the condensate system, consisting of high purity Water with less than 10 ppm of amines added. The pH of the waste water did not exceed 9.7 at any time.
The cause of non-compliance was a misunderstanding by plant personnel. It was thought that the pH limits did not apply to the waste water because it was being discharged through an alternate discharge point instead of being discharged through the waste neutralizing tank (MP 104A) as the waste neutralizing system was out-of-service for maintenance.
The total volume of waste water discharged during this period was estimated to be 175,000 gallons.
Because the high pH waste water was diluted by 2.4 million gallons per minute, there was no impact on the receiving waters. No accelerated or additional monitoring was performed.
To prevent recurrence site personnel have been trained on the pH requirements for discharge.
