The proposed rule would provide de minimus air quality benefits in downwind areas with extremely high costs – estimated by EPA at $22 billion discounted 2016 dollars for the 2023-2042 period. The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 ppb by 2025.
