Final Geologic Sequestration Rules - Class VI Injection Well

U.S. Environmental Protection Agency (EPA) finalized two rules related to the capture and sequestration of carbon dioxide. Carbon capture and sequestration (CCS) technologies have the potential to enable large emitters of carbon dioxide to significantly reduce greenhouse gas emissions. This technology allows carbon dioxide to be captured at stationary sources and injected underground for long-term storage in a process called geologic sequestration. The new rules aim to protect drinking water and to track the amount of carbon dioxide that is sequestered from facilities that carry out geologic sequestration.

Drinking Water Protection:
EPA finalized a rule that sets requirements for geologic sequestration of carbon dioxide, including the development of a new class of injection well called Class VI, established under EPA’s Underground Injection Control (UIC) Program. The rule requirements are designed to ensure that wells used for geologic sequestration of carbon dioxide are appropriately sited, constructed, tested, monitored, and closed. The UIC Program was established under the authority of the Safe Drinking Water Act.

Greenhouse Gas Reporting:
EPA also finalized a rule on the greenhouse gas reporting requirements for facilities that carry out geologic sequestration. Information gathered under the Greenhouse Gas Reporting Program will enable EPA to track the amount of carbon dioxide sequestered by these facilities. The program was established in 2009 under authority of the Clean Air Act and requires reporting of greenhouse gases from various source categories in the United States.
