Colorado Underground Injection Control Permit (14-CO-c)

The United States Environmental Protection Agency (EPA) has not delegated authority to Colorado to regulate Class V underground injection control wells. However, the construction of Class V injection wells used to reinject spent geothermal fluids is regulated by the Colorado Division of Water Resources and requires a geothermal reinjection well drilling permit.
