Summary/Abstract
The EPA issues permits for CO2 injection wells, where captured CO2 is injected through deep underground wells into geologic formations in order to reduce CO2 emissions reaching the atmosphere (known as Class VI wells). In some cases, EPA delegates authority to states, known as program primacy, to administer underground injection programs and issue Class VI permits.
This report discusses the statutory and regulatory framework for permitting Class VI wells; describes Class VI permit application requirements and the permit review process; describes state primacy requirements and the primacy review process; and highlights selected policy issues for Congress.
