Arnold & Porter has released a legal analysis examining how recent North Dakota court rulings reshape the state's pooling statutes for carbon capture and storage (CCS) operators. The advisory, "Carbon Capture Pooling Statutes After North Dakota Rulings: Lessons for Regulators and Developers," addresses unitization doctrine at a moment when Class VI well permitting is accelerating across sequestration-active states.

The publication targets the legal mechanism that lets an operator combine fractional mineral and pore-space interests into a single development unit. For CCS projects, pooling statutes must reconcile surface rights, pore-space ownership, mineral estates severed from the surface, and federal primacy review under the Safe Drinking Water Act. That intersection has produced the litigation now under analysis.

What does the ruling recalibrate?

Pooling doctrine dates to the oil and gas era, when forced unitization solved the problem of one operator holding up development across a common reservoir. CCS imports the same logic: without effective pooling, fragmented mineral and surface estates can stall a sequestration project long before drilling begins.

A Class VI permit under the federal Underground Injection Control program contemplates injection volumes and pressure regimes that require contiguous, controlled pore space, not a checkerboard of fractional consents.

The North Dakota rulings now under Arnold & Porter's commentary appear to recalibrate how courts read consent thresholds among working-interest owners, the rights of non-consenting mineral and pore-space holders, and the role of state agencies in compelling unitization over dissent.

Why a two-track legal advisory?

Arnold & Porter's "lessons for regulators and developers" subtitle signals two distinct reading lists with overlapping but distinct stakes. State oil and gas commissions and mineral-resource agencies will look for guidance on rulemaking, order drafting, and statutory amendment choices that anticipate further judicial review.

Developers with acreage in North Dakota, particularly those pursuing Class VI permits in saline formations, will look for title-curative steps and unitization-petition drafting practices that survive the new standard.

The dual framing reflects how pooling decisions cut both ways. Regulators who overreach risk appellate reversal. Developers who under-document title risk permit delay or invalidation when a competitor or non-consenting interest challenges the unit.

What changes next?

The regulatory milestone that will decide the next chapter is the next state commission order applying the rulings, alongside any further appellate review of the underlying decisions. Operators weighing North Dakota projects should track:

• Industrial Commission and Department of Mineral Resources orders on pooling petitions filed after the rulings
• Appellate review of any trial-court decision appealed from the rulings
• EPA determinations on Class VI primacy-related permit conditions tied to unitization

The market milestone that follows is the next financial investment decision on a CCS project in the state.

Until pooling doctrine stabilizes, announced capacity across North Dakota's saline formations will continue to diverge from permitted, financed, and operational tonnage.

The Arnold & Porter analysis offers the legal profession's most timely read on which gap-closing steps sit with the courts, which sit with the agencies, and which sit with developers working their acreage stacks.
