The U.S. Environmental Protection Agency (EPA) is tasked with the responsibility of establishing and enforcing any regulations associated with injecting and storing carbon dioxide (CO2) in the subsurface. In December 2010, EPA finalized minimum Federal requirements under the Safe Drinking Water Act (SDWA) for underground CO2 injection for the purpose of geologic storage. This final rule applies to owners or operators of wells that will be used to inject CO2 into the subsurface for the purpose of long-term storage. It establishes a new class of well, Class VI, as part of the Underground Injection Control (UIC) Program. Read More!

The U.S. Department of Energy (DOE) has no responsibility in developing regulations for underground CO2 storage. However, DOE does support the continued development and field testing of technologies that can be used by operators to verify that the regulations relating to the safe storage of CO2 underground are met.

Myth: Current regulations are inadequate to address the underground CO2 injection.
Reality: There are both Federal and state regulations that govern underground CO2 injection.
