ExpiredPAEP Webinar – November 15, 2021

Thermal Discharge Compliance

Monday, November 15, 2021
at 12:00 (Noon) Eastern


All facilities discharging heated water to Waters of the State must comply with federal and/or state water quality standards for temperature.  Thermal discharge limits are specified in a facility’s National Pollutant Discharge Elimination System (NPDES) permit for the discharge outfall.  The point of compliance may be at the actual outfall or at the edge of a specified mixing zone.

If compliance with water quality standards cannot be achieved, the discharger may request a variance under the CWA 316(a) and/or applicable state standards.  Typically, this will require a suite of studies to demonstrate that the water quality standards are more stringent than necessary and that a proposed alternative thermal limit has not caused appreciable harm and will ensure the protection and propagation of a balanced indigenous community on the water body receiving the thermal discharge.  If compliance has not recently been demonstrated through studies, the Director may require new studies be completed to ensure compliance.

A brief summary of the EPA guidance, study requirements, and a case study will be presented.
