Water Quality - Permits

     

     

     

    Welcome to the Permits Section web page. We issue permits for discharges of pollution to waters of the state, including groundwater.

    Our job is to ensure that the permits we write and issue are protective of the uses of those waters, like drinking water, aquatic life, agriculture, and recreation.

     

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

    Basin Schedule for Individual Permits


    Individual process water permits to surface water are renewed under a basin schedule, meaning the Permits Section starts renewing these permits the year after the Water Quality Control Commission basin hearing.

    The division does not currently have the resources to renew all permits every time it works in a basin. The division uses this criteria to prioritize individual permit renewals. 


    When the division is working in a basin, it regularly shares its progress during the quarterly permit webinars.
