Water Quality - Permits

#FFFFFF
River

Welcome to the Permits Section

We issue legally binding permits for the discharge of pollutants to state waters, including surface waters and some groundwater.

Our job is to ensure that the discharge permits we issue protect the beneficial uses of those waters (domestic water supply, aquatic life, agriculture, recreation, and wetlands.)

Here is a quick overview of how permits work in Colorado.

  • Senate Bill 89-181 governs the protection of groundwater quality and discharges to groundwater among several implementing state agencies.
  • The discharge of dredge and fill materials into state waters is excluded from the definition of discharge pollutants and is regulated by a different program.
  • The Environmental Agriculture Program regulates the discharge of pollutants to state waters and other items related to animal feeding operations.

Basin schedule for individual permits

Individual process water permits to surface water are renewed under a basin schedule. Each year, the Water Quality Control Commission holds a basin hearing in June which becomes effective in December. The Permits Section starts renewing permits in the basin the year after the Commission hearing.
