Colorado Class VI Primacy Application Statement

The Environmental Protection Agency (EPA) is providing notice regarding Colorado's application for primacy over its Class VI Underground Injection Control (UIC) program. This application seeks authorization for the state to administer and enforce the federal Class VI program within its jurisdiction, which pertains to the injection of carbon dioxide for geologic sequestration.

This notice initiates a public comment period, allowing interested parties to review Colorado's application and submit feedback to the EPA. The EPA will consider these comments as part of its evaluation of whether Colorado's program meets the requirements for primacy. Further actions will depend on the outcome of this review and public consultation process.
