This plan is part of the state's efforts to meet the 1997 8-hour ozone national ambient air quality standard. The approval makes certain commitments federally enforceable as part of Pennsylvania's Implementation Plan. The plan focuses on ongoing air quality monitoring and measures to ensure that the area continues to meet required standards.
