What Does PSES Stand For?

PSES stands for Pretreatment Standards For Existing Sources

PSES, or Pretreatment Standards for Existing Sources, refers to regulatory guidelines established under the Clean Water Act to limit the discharge of pollutants from existing industrial sources into wastewater treatment facilities. These standards aim to protect water quality by ensuring that industries implement effective pretreatment processes before releasing their effluents. PSES play a critical role in safeguarding the environment and public health by setting permissible limits on specific contaminants and promoting compliance with environmental regulations.
