  • Overview Groundwater Discharge

    This Overview of the Colorado State Ground Water Discharge Permit Program provides information on the regulatory and permitting requirements that apply to domestic wastewater treatment systems that potentially discharge to ground water, such as impoundments, land application systems, and septic tank systems.

  • Water Quality Control Commission Regulations:

    • Regulation No. 61 - Colorado Discharge Permit System Regulations

    • Regulation No. 62 - Regulations for Effluent Limitations

    • Regulation No. 41 - The Basic Standards for Ground Water

    • Regulation No. 42 - Site-Specific Water Quality Classifications and Standards for GW

    • Regulation No. 39 - Colorado River Salinity Standards
       

  • WQCD Engineering Section (e.g., District Engineers, Domestic Wastewater Treatment Works Site Application Process, Wastewater Design Review).

  • Water Well Construction Rules - See Section 14 for minimum construction standards for monitoring wells.  - Exit to Office of the State Engineer

  • Guidelines for Estimating Leakage from Existing Sewage Lagoons (These guidelines were developed and implemented by the State of Oregon Department of Environmental Quality and provide just one example of the Colorado WQCD's expectations for the contents and approach of a lagoon seepage rate study.)

  • Water and Wastewater Facility Operators Certification Board

  • Underground Injection Control (UIC) Program - Exit this site
    Underground injection wells are primarily used to dispose of wastes into the subsurface and have the potential to adversely affect underground sources of drinking water.  The UIC Program in Colorado is administered by the USEPA Region 8.

***  Note that both the  Water Quality Control Division (WQCD) Permits Section and the Solid Waste Program in the Hazardous Materials and Waste Management Division  (HMWMD) regulate activities impacting ground water.  The respective roles of the WQCD and HMWMD are described in the memorandum:  Water Quality Control Division and Hazardous Materials and Waste Management Division Solid Waste Program Coordination on Regulation of Groundwater Impacts Under SB-181.
