Primacy Certainty Act of 2023

The Primacy Certainty Act of 2023 sets clear deadlines for the EPA to review state applications for primary enforcement authority over Class VI wells (used for carbon dioxide injection). If the EPA fails to act within 180 days, it must provide a written explanation of delays; if no decision is made within 210 days total, the application is automatically approved. This directly affects states seeking to regulate Class VI wells, preventing indefinite federal delays in transferring oversight authority. Key provisions include requiring the EPA to work with states on pre-application steps, designate a single EPA contact per state, and transfer pending permits upon approval. The bill ensures states can assume regulatory control without federal conditions beyond existing requirements.
