OFFSITE NOTIFICATION DUE TO EXCEEDING CHLORINE EFFLUENT LIMIT
"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].
