Senate Conservation committee deadlocks on House Bill 457 on carbon capture permitting and community protections
Summary
The Senate Conservation Committee split 3-3 on a do-pass recommendation for House Bill 457, a bill that would set state standards for carbon capture, direct air capture siting and CO2 storage; the tie left the bill without a committee recommendation and it will not proceed from the committee.
A Senate Conservation Committee tie vote left House Bill 457 without a recommendation after hours of testimony and questions about notice, well pressure limits and climate benefits.
Supporters told the committee the bill would allow the Legislature to set state-specific standards for CO2 injection and community engagement. Opponents and several senators pressed for more detail about who must be notified, how pressure limits will be set and whether primacy — state oversight instead of federal — is appropriate.
The dispute centered on technical and procedural requirements in the draft. One senator called the proposed notification requirements “gonna be a nightmare for any title attorney,” noting the draft requires identifying and notifying owners of surface, mineral and pore‑space estates within one half‑mile of a proposed sequestration unit. Committee members also probed injection pressure limits and safety modeling; witnesses said permitted injection pressures would be calculated similarly to existing saltwater disposal formulas and that CO2’s compressibility changes some reservoir behavior compared with water.
Experts described carbon capture and direct air capture as mature technologies in some settings and argued they are needed both to remove legacy CO2 from the atmosphere and to offset emissions from high‑temperature industrial processes. An expert witness said CO2 placed in a suitable formation initially dissolves into formation water (about 30% in days–weeks) and then, over years to centuries, a portion mineralizes and becomes immobile. The witness also described direct air capture efficiencies when powered by low‑carbon energy and said many projects rely on the federal Section 45Q tax credit to be financially viable.
Committee members raised other concerns: whether the state should seek primacy (taking over permitting from the EPA), how tribal consultation and community‑benefit agreements would be required and whether the state’s agencies have capacity to enforce new rules. One senator urged caution about giving state agencies more responsibilities without additional resources and recommended relying on existing EPA standards rather than immediate state primacy.
A do‑pass motion for House Bill 457 was moved and seconded, and the committee recorded a 3‑3 tie (Yes: Senator Zelle, Senator Scott, Senator Townsend; No: Senator Charlie, Senator Pope, Senator Cynthia Lopez). Under committee rules, the tie meant no positive recommendation; the chair said the bill “does not proceed” from the committee.
What remains unsettled are the specific notice requirements, who is legally recognized as the owner of pore space for contracting and whether the Legislature will require tribal consultation and community‑benefit agreements beyond federal rules. Proponents urged the state to adopt standards now so New Mexico can shape how operators receive permits and secure federal tax credits; opponents urged more guardrails and clarity before granting state authority.
The committee did not direct staff to take further action on House Bill 457 at this meeting; the record shows no assigned follow‑up tasks or amendments adopted during the hearing.
Votes at a glance: Do‑pass motion, House Bill 457 — motion failed in committee by tie (3 Yes, 3 No); resulting status — no committee recommendation; the bill does not proceed from the committee.
