California Code, Public Resources Code - PRC § 71463

The State Geologist shall report seismic activity or leakage of carbon dioxide from a carbon dioxide capture, removal, or sequestration project to the state board and may recommend changes in the operations of the project to the state board.  The state board may require changes in operations of a carbon dioxide capture, removal, or sequestration project to ensure public and environmental health and safety, including, but not limited to, a mandatory pause in operation, if the monitoring and reporting detects increased seismicity or carbon dioxide leakage outside of the geologic storage reservoir.
