Primacy Certainty Act of 2025

The Primacy Certainty Act of 2025 sets clear deadlines for the EPA to review state applications for primary control over Class VI wells (used for carbon dioxide storage). It requires the EPA to provide detailed written explanations if it misses a 180-day deadline for reviewing applications, and automatically approves applications if the EPA fails to act within 30 days after that deadline. States seeking control must already have primary enforcement authority for other well types, and the bill mandates EPA transfer of pending permits to states once approval is granted. This directly affects states applying to manage Class VI well regulations, reducing uncertainty in the approval process.
