  • The Clean Water Act created the NPDES ( National Pollutant Discharge Elimination System) Program.
    • Requires permits to discharge process water.
  • 1990 – Stormwater Regulations added

  • EPA has given The State of Colorado the authority to issue and enforce NPDES permits
  • Colorado created the Colorado Water Quality Control Act
  • Colorado renamed NPDES permits, CDPS (Colorado Discharge Permitting System) permits.

A: ANY WATER DISCHARGED FROM THE INDUSTRIAL SITE NEEDS A PERMIT. (except water associated with: fire fighting activities, springs, or landscape irrigation return flow.)

  • Stormwater General Permits
