Underground Injection
Control (UIC) Program

General Information

The UIC Program at KDHE is administered by the UIC Unit within the Geology Section. The purpose of the UIC Program is to protect public health and safety, and the environment from injection activities. Injection well activities include the disposal of industrial waste into deep geologic formations, the solution mining of salt formations and the shallow injection of a variety of nonhazardous fluids below the land's surface.

The UIC program categorizes injection wells into five classes of wells. These are:

  • Class I: Wells used to inject hazardous wastes or dispose of industrial and municipal fluids beneath the lowermost formation containing, within one quarter (1/4) mile of the well bore, a source of fresh or usable water.
  • Class II: Wells used to inject fluids associated with the production of oil and natural gas or fluids/compounds used for enhanced hydrocarbon recovery. These wells normally inject below the lower-most fresh or usable water bearing zone except in cases where this zone is hydrocarbon producing. These wells are regulated by the Kansas Corporation Commission. The contact for the KCC is (316) 337-6197.
  • Class III: Wells which inject fluids for the extraction of minerals.
  • Class IV: Wells which dispose of hazardous or radioactive wastes into or above a fresh or usable water bearing zone. Class IV wells are prohibited.
  • Class V: Wells not included in other classes. Typically Class V injection wells are shallow wells used to place a variety of fluids below the land surface.
