Regulating Geologic Sequestration in the United States: Early Rules Take Divergent Approaches

This journal article evaluates approaches taken by several U.S. states—in coordination with the U.S. Environmental Protection Agency (EPA)—toward geological sequestration (GS) of carbon dioxide. The authors present rules that take widely varying approaches to regulating GS, and point out that the new rules are very different from the existing Underground Injection Control (UIC) Program rules. The authors also comprehensively compare key elements impacted by the rules, such as monitoring requirements, long-term liability, environmental and health impacts assessment, and risk assessments.
