Units with existing advanced NOx controls must optimize their utilization by 2023. The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 enjoyed ozone reductions of 3 to 5 ppb or more. Ozone concentrations in over 70 percent (i.e., ppb by 2025. million tons.
