Underground injection control well registration requirements & information

If you do not meet one of the exemptions above your injection well must be registered with us. There is no fee to register injection wells.

Authorized wells do not need a permit

The majority of the injection wells in Washington are rule-authorized — which means the injection well does not need a permit.

To be rule-authorized, a UIC well must meet two requirements:

• The well must be registered
  All well owners must provide inventory information by registering their UIC wells with us —  or with the EPA, Region 10, if the wells are located on tribal land.
   
• Water discharged from the well(s) must meet the non-endangerment standard
  The non-endangerment performance standard prohibits injection that allows the movement of contaminated fluids into groundwater.

Review or update the status of your well

You can view the approval status of your well online by reviewing your application.

The injection well owner (or designee) is responsible for keeping us informed of the status of the well, including whether the well is closing, changing ownership, or changing its use.

If information about your registration needs to be changed, please contact the UIC program coordinator.
