EPA ECHO Thermal Effluent Violations

From Open Energy Information

This site identifies electric power facilities that reported a thermal effluent violation from January 2012 to March 2016 according to the EPA ECHO reporting website. Further details about these incidents can be found in the report, “Water-related power plant curtailments: An overview of incidents and contributing factors.”

Point sources that discharge effluent to waters of the United States are subject to regulations under the Clean Water Act (CWA). These sources must obtain a National Pollution Discharge Elimination System (NPDES) permit from the jurisdiction that has been granted permitting authority, which often are state environmental agencies. NPDES permits establish pollution monitoring criteria and sets limits on pollutant concentrations that can be discharged. If a source discharges a pollutant above permit limit, this is considered a violation and must be reported to the permitting agency.

Plants can request a variance from thermal CWA discharge limits under Section 316 (a) of the CWA, which allows the NPDES permitting authority to establish alternate thermal discharge limits as long as the discharger can prove that increased temperature discharges still protect the receiving water body’s “balanced, indigenous population of shellfish, fish, and wildlife.”

Each NPDES permit is different for individual facilities and can require different limit requirements. For example, some permits set a limit on monthly maximum temperature discharge and some set limits on daily maximum temperature. Some permits have seasonally dependent limits, generally with higher temperature discharge limits in the summer months.

Each pin represents a thermoelectric power plant that reported a thermal effluent violation. Note that plants may or may not have experienced multiple violations during this time frame.
