EPA Grants Class VI Primacy to Colorado, Texas, and Arizona
What happened
The EPA published a final rule approving Colorado’s application for primary enforcement responsibility over Class VI injection wells under the Safe Drinking Water Act. This rule, which takes effect November 12, 2026, designates the state agency as the primary authority for reviewing and enforcing Class VI requirements on non-Indian lands. Colorado is the seventh state to receive this primacy, joining Louisiana, West Virginia, Wyoming, Arizona, North Dakota, and Texas.

Why it matters
This change is important for carbon capture and storage projects because permit applicants will primarily work with the state agency that oversees both surface development and geologic storage components. The state agency will be responsible for reviewing permit applications, issuing permits, and monitoring compliance.
