The US Environmental Protection Agency (EPA) has granted West Virginia primary enforcement responsibility of Class VI wells under the Underground Injection Control Program.
The state is the fourth—after Louisiana, North Dakota, and Wyoming—given primary authority by EPA to oversee and administer its Class VI program, known as primacy. The authority allows the state to permit wells designed to inject carbon dioxide (CO2) into deep rock formations which serve as critical infrastructure for deploying carbon capture, utilization, and storage projects.
