Colorado Stakes Its Claim in the Carbon Rush

The EPA proposes handing Colorado state-level control over CO₂ injection permits, cutting timelines and unlocking EOR investment across the Rockies

7 May 2026

US federal regulators have proposed granting Colorado state-level control over permits for Class VI injection wells, the regulated infrastructure used to store carbon dioxide permanently underground. Published on 19 March 2026, the proposal would remove the federal approval layer from a process that has historically taken more than two years to complete.

Oversight would sit with Colorado's Energy and Carbon Management Commission, whose Class VI regulations, adopted in December 2024, meet or exceed federal standards under the Safe Drinking Water Act. A virtual public hearing took place on 23 April 2026; the comment period closed on 4 May. A final EPA ruling is expected before year-end.

Timing matters. A 2025 federal law equalised the Section 45Q tax credit at $85 per tonne for both enhanced oil recovery (EOR) linked to CO₂ storage and standalone geological sequestration, closing a longstanding financial gap between the two activities. With economics now aligned, regulatory speed has become the primary constraint on project timelines.

Five states already hold primary enforcement authority over Class VI wells. Texas received the designation in November 2025 and now oversees the largest pipeline of pending applications in the country. Colorado's approval would extend state-controlled carbon governance into the Rocky Mountain region, opening new ground for CO₂-EOR hub development.

Whether EPA moves quickly enough to match industry expectations remains uncertain. Its final determination will set the regulatory template for further state primacy transfers across the western United States.
