OFFSITE NOTIFICATION MADE FOR NPDES NONCOMPLIANCE
"This event is being reported in accordance with 10 CFR 50.72(b)(2)(xi). On May 6, 2012, during daily chlorination activities, it was identified that the National Pollutant Discharge Elimination System (NPDES) permit limit for Total Residual Chlorine was exceeded between approximately 0935 hours [EDT] and 0947 hours [EDT] when the noncompliance was corrected. The maximum measured value was 0.29 mg/L, which exceeded the NPDES Maximum Concentration Limit of 0.2 mg/L.
"On May 6, 2012, at approximately 1930 hours [EDT], a 'Noncompliance Notification for Exceedance of a Daily Maximum Discharge Limit' was made to the Ohio Environmental Protection Agency. The cause of the NPDES permit noncompliance is under investigation. Chlorination evolutions have been suspended pending investigation results. At the time of the event, the plant was in Mode 1 at 100 percent rated thermal power.
"This event is also being reported in accordance with the plant's operating license, appendix B, Environmental Protection Plan, which states, in part, that any occurrence of an unusual or important event that indicates or could result in environmental impact causally related to plant operation shall be recorded and reported to the NRC within 24 hours followed by a written report."
The licensee notified the NRC Resident Inspector.
