Should states rather than the federal government regulate underground carbon sequestration?

The US Environmental Protection Agency has granted Colorado authority to manage carbon dioxide underground injection wells, known as Class VI wells. The Energy and Carbon Management Commission will now handle all state-level permitting and enforcement under the Safe Drinking Water Act.

Why it matters

Operators involved in carbon sequestration projects gain a more direct, state-level regulatory path for well permits. By securing this primacy, Colorado assumes control over the technical and legal review processes formerly managed by federal oversight.

Colorado is the seventh state to achieve Class VI primacy, gaining the authority to oversee carbon storage wells under Section 1422 of the Safe Drinking Water Act. This shift follows the state's prior experience with Class II well regulation, which it has managed since 1984.

The players

Energy and Carbon Management Commission

The Colorado state body responsible for the regulation of underground carbon dioxide injection and geological sequestration.

US Environmental Protection Agency

The federal agency tasked with protecting human health and the environment through the enforcement of national standards.

The details

The EPA's final rule empowers the Energy and Carbon Management Commission to conduct all technical and legal reviews for carbon sequestration projects. The commission now oversees the full lifecycle of Class VI well compliance and enforcement, including the transition of one pending permit application from federal oversight. The EPA maintains jurisdiction over all other well classes and tribal lands throughout the state.

1984: Colorado received its initial primacy over Class II wells.
October 13, 2026: The EPA officially authorized Colorado to regulate Class VI wells.

Market Landscape

This transition aligns with the state certification process established under the Safe Drinking Water Act section 1422. Colorado becomes the seventh state to formally adopt these federal standards for carbon storage oversight.

Operators currently seeking or holding Class VI well permits in Colorado should align their compliance filings with the Energy and Carbon Management Commission. Ensure all project documentation reflects the new state-led regulatory authority to avoid delays in processing.

The takeaway

The delegation of oversight to the Energy and Carbon Management Commission provides a singular point of contact for future sequestration permits. Operators should review the commission's updated filing portal to confirm that all current applications are correctly registered under state jurisdiction.
