Cal. Pub. Res. Code § 3132 — Underground Injection Control

(a) For purposes of this section, the following definitions apply:

(1) “Carbon dioxide capture project” means a project that uses a process to separate carbon dioxide from industrial, commercial, or energy-related sources, other than oil or gas production from a well, and produces a concentrated fluid of carbon dioxide with the intent of preventing emission of the carbon dioxide into the atmosphere.

(2) “Carbon dioxide capture, removal, or sequestration project” means a carbon dioxide capture project or carbon dioxide removal project, that seeks to provide for the long-term isolation or utilization of the carbon dioxide from the atmosphere through storage in a geologic formation.

(3) “Carbon dioxide removal project” means a project that uses a process to remove carbon dioxide from the atmosphere.

(4) “Concentrated carbon dioxide fluid” means a fluid that contains concentrated carbon dioxide that is proportionately greater than the ambient atmospheric concentration of carbon dioxide.

(b) An operator shall not inject a concentrated carbon dioxide fluid produced by a carbon dioxide capture, removal, or sequestration project into a Class II well for purposes of enhanced oil recovery, including the facilitation of enhanced oil recovery from another well.
