Ozone Planning Efforts

Planning for air pollution is a collaborative and iterative process. As the health science improves, the Environmental Protection Agency (EPA) reviews and if necessary revises the health based standards (known as NAAQS). This revision begins a cycle of planning for each state agency to determine the status compared to the standard; evaluate the programs and strategies necessary to ensure maintaining or attaining the standard; implementing the standards and evaluating if those strategies have been effective. Below are DEEP's planning efforts and EPA responses for each standard.
