| Title | Offsite Notification Due to Exceeding Chlorine Effluent Limit |
| Event Description | On August 24, 2017 a malfunction internal to the River Water Chemistry Control System resulted in measurable free available chlorine levels over a one-hour period at the station outfall to the Susquehanna River. The chlorine levels exceeded the station NPDES [National Pollutant Discharge Elimination System] permit effluent limitations. The River Water Chemistry Control System was shutdown until the condition is corrected.
The concentrations released did not threaten the downstream users or the environment. Pennsylvania Department of Environmental Protection was notified of the NPDES non-compliance on August 25, 2017 at 1115 [EDT]. Pursuant to 10 CFR 50.72(b)(2)(xi), this notification satisfies the requirement to notify the NRC of the occurrence of any event or situation related to the health and safety of the public or onsite personnel, or protection of the environment, for which notification to the other government agencies has been made. The NRC Resident Inspector has been notified. Notified DOE, EPA, USDA, HHS, and FEMA. |
