The Air Quality Conformity Report documents provide an analysis of the air quality implications of the current York Area Metropolitan Planning Organization (MPO), Transportation Improvement Program (TIP) and Long-Range Transportation Plan (LRTP).
Since vehicular emissions contribute to ozone and Particulate Matter2.5 (PM2.5) violations, the federal Clean Air Act requires transportation planners in nonattainment and maintenance areas to consider the air quality impacts of their proposed plans, programs, and projects. These activities, if subject to federal involvement, must be shown to conform based on the requirements for each pollutant.
The York Area MPO (encompassing York County) must make separate conformity determinations for the two criteria pollutants for which it is in maintenance and nonattainment: ozone and PM2.5. For the 2006 PM2.5 daily standard, an affirmative conformity determination is made only for York County within this document. A final conformity determination approval by the U.S. Department of Transportation (US DOT) for this standard can only occur if all areas within the nonattainment area demonstrate conformity. This requires positive conformity determinations by the Harrisburg and Lebanon MPOs.
These documents and supporting analysis demonstrate transportation conformity to the 1997 8-hour ozone and the 1997 annual and 2006 daily (24-hour) fine particulate (PM2.5) National Ambient Air Quality Standards (NAAQS) and replaces the previous approved conformity demonstration of the TIP and LRTP. This document ensures that the findings meet all current ozone and PM2.5 criteria established by the U.S. Environmental Protection Agency (EPA).
