Guidance Documents

This page contains a variety of downloadable Guidance documents that explain Surface Water Quality Standards procedures. 

Triennial Review Working Group

Wyoming’s surface water quality standards include designated uses, water quality criteria, and antidegradation provisions to protect and restore Wyoming’s surface waters. 

The standards are developed to be consistent with the Wyoming Environmental Quality Act and federal Clean Water Act using scientific principles, available data and supporting information, as well as public input.

  • Changes to designated uses
  • Site-specific water quality criteria
  • Discharger-specific variances
  • Guidance for Options to Modify Standards

  • Wyoming’s surface water quality standards are currently under review, as required by the federal Clean Water Act

  • Efforts to Address Nutrient Pollution in Wyoming’s surface waters

  • In anticipation of updating Wyoming fisheries designated uses and associated temperature criteria, Wyoming DEQ partnered with researchers at the University of Wyoming to compile information on thermal tolerances and distributions of fish.
