EPA Proposes Class VI Primacy Handoff for Utah Carbon Storage

The EPA has proposed granting Utah primary enforcement authority over Class VI carbon dioxide injection wells, moving permitting for geologic sequestration out of federal hands and into the Utah Division of Oil, Gas and Mining (UDOGM).

The proposed rulemaking, issued under Section 1422 of the Safe Drinking Water Act (SDWA), sets a written comment deadline of December 7, 2026, with a virtual public hearing scheduled for December 3, 2026. If finalized, Utah joins the short list of states that regulate their own Class VI wells — the well class that governs long-term subsurface CO2 storage for carbon capture, utilization and storage (CCUS) projects.

Utah filed its formal primacy application on December 23, 2025. Roughly a year later, the federal process has reached the public-consultation stage, the last procedural gate before a final determination.

What does primacy actually change?

Right now, any developer seeking to drill and operate a Class VI injection well in Utah works through federal EPA regional oversight. That path is widely viewed in the industry as slower and less predictable than state-run programs, and it has been a recurring bottleneck for CCUS project scheduling across the Intermountain West.

Under the proposed rule, UDOGM would gain the authority to process, issue and enforce Class VI permits for industrial carbon storage projects inside state borders. The state agency would still have to comply with minimum federal SDWA protective standards — primacy transfers administration, not the underlying drinking-water safeguards.

In plain terms: project developers in Utah would file with Salt Lake City instead of the EPA regional office, provided the state keeps meeting federal floor requirements.

How the comment process works

The EPA has laid out a two-track consultation ahead of its final decision:

• Public hearing: A virtual session via Zoom on Thursday, December 3, 2026, from 5:00 to 7:00 pm MDT. Registered stakeholders can present oral testimony, capped at three minutes per commenter.
• Written comments: Formal docket submissions are open through December 7, 2026, under Federal Register Docket ID No. EPA-HQ-OW-2026-0496 at regulations.gov.

Once the comment window closes, the EPA will weigh public input against the technical documentation in Utah's application before deciding whether to add the state to the Class VI primacy list.

Why Utah, why now

The proposal fits a broader pattern across the Intermountain West, where states are pursuing Class VI primacy to accelerate CCUS deployment by streamlining environmental permitting for long-term subsurface carbon sequestration. Colorado has already secured the same authority from the EPA, and Utah's application tracks the same logic: state-level permitting is positioned as a way to shorten timelines for storage projects that anchor capture investments upstream.

For the circular carbon economy, the stakes are straightforward. Class VI wells are the compliance backbone for any durable geologic storage claim. Where permitting sits, and how fast it moves, shapes which projects reach final investment decision.

There's a caveat worth holding onto. This is a proposed approval, not a granted one — announced capacity in the regulatory sense, not built. Until the EPA issues its final rule, Utah's Class VI applicants remain in the federal queue.

What happens next

The milestone that decides everything is the EPA's final determination after December 7, 2026. Watch the docket at regulations.gov for the comment volume and any technical objections — those usually telegraph whether final approval lands cleanly or slips into renegotiation.
