Wastewater Variances
  
 
National Summary
The Clean Water Act (CWA) provides for modifications of its wastewater discharge standards in exceptional cases. These modifications are called variances. Facilities discharging wastewater may request variances from general industry pretreatment standards for discharges into publicly owned treatment works (POTW) or from NPDES effluent limitations for discharges from individual facilities. Specific effluent and discharge standards have to be met by an applicant before EPA will grant a variance.
