On June 9, 2025, the U.S. Environmental Protection Agency (EPA) proposed granting the State of Texas primary enforcement authority—commonly referred to as “primacy”—over the permitting and regulation of Class VI underground injection control (UIC) wells under the Safe Drinking Water Act (SDWA). This would authorize the Texas Railroad Commission (RRC) to regulate the geologic sequestration of carbon dioxide (CO₂) through Class VI wells—an essential component of carbon capture and storage (CCS) infrastructure.

From Shale to Salt: Texas Supreme Court Applies Uniform Rule for Ownership of Subsurface Caverns
In a closely watched opinion issued on May 16, 2025, the Texas Supreme Court in Myers-Woodward, LLC v. Undergrounds Services Markham, LLC, — S.W.3d —, No. 22-0878, 2025 WL 1415892 (Tex. May 16, 2025) resolved a long-uncertain issue of subsurface property rights in the context of salt dome mining. The Court held that, unless a deed provides otherwise, subsurface voids created by salt mining operations are owned by the surface estate holder, not the mineral interest holder. By rejecting a salt-specific rule, the Court harmonized ownership principles across subsurface formations, applying a uniform rule regardless of the type of mineral removed.
Carbon Sequestration Can Combat Global Warming, Sometimes in Unexpected Ways
Whether by land, by sea or through human innovation, carbon sequestration is likely coming to (or already happening in) a destination near you. As our planet, overdosed on greenhouse gases, battles climate disasters, a logical solution is to simply stop pumping carbon dioxide into the air. Legislation worldwide is aimed at that target, but reducing output alone may not be enough. There are still billions of tons of extra CO2 already in the atmosphere—this crossroads is where sequestration comes into play.
