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

The US Environmental Protection Agency has authorized Colorado to manage the permitting and enforcement of underground carbon dioxide injection wells. This decision makes Colorado the seventh state to achieve Class VI primacy under the Safe Drinking Water Act.

Why it matters

Granting state-level primacy ensures that local authorities can directly oversee geological carbon sequestration projects while meeting rigorous federal safety standards. This shift streamlines the regulatory process for businesses looking to implement carbon capture technology within the state.

Colorado is now the seventh state to receive Class VI primacy, building on the authority it first gained over Class II wells in 1984. The state program must adhere to the requirements established under section 1422 of the Safe Drinking Water Act.

The players

US Environmental Protection Agency

This federal agency is responsible for protecting human health and the environment by writing and enforcing regulations based on laws passed by Congress.

Energy and Carbon Management Commission

This Colorado state body is responsible for regulating oil and gas operations and carbon management to protect public health and the environment.

The details

The Energy and Carbon Management Commission will now take over jurisdiction from the EPA for overseeing Class VI well operations, including one pending permit application. The agency conducted a technical and legal review to ensure the state program aligns with federal mandates for protecting underground water sources.

1984: Colorado received primacy over Class II wells.
October 13, 2026: The EPA published the final rule granting Class VI authority.

Market Landscape

This transition marks a significant shift in regional regulatory control, empowering state agencies to manage infrastructure critical to the carbon capture industry. The move follows the framework established by the Safe Drinking Water Act section 1422 regarding underground injection controls.

The transfer of authority streamlines the approval process for energy projects, potentially accelerating the development of carbon sequestration sites in the state. Residents may see more localized oversight of industrial projects as the commission assumes direct responsibility for compliance.

The takeaway

Colorado joining the list of states with Class VI primacy signals a broader trend of delegating environmental oversight to state-level commissions. Businesses in the carbon management sector should prepare for updated permitting procedures now that state authorities hold local jurisdiction.
