Final PM2.5 Rule Released. EPA published a final rule on May 6 in the Federal Register that addresses PM2.5 precursor emissions in transportation conformity. Specifically, the final rule adds the following transportation-related PM2.5 precursors to the transportation conformity regulations: nitrogen oxides (NOx), volatile organic compounds (VOCs), sulfur oxides (SOx), and ammonia (NH3). The final rule also specifies when each of these precursors must be considered in conformity determinations in PM2.5 nonattainment and maintenance areas before and after PM2.5 state air quality implementation plans (SIPs) are submitted. See: http://www.epa.gov/fedrgstr/EPA-AIR/2005/May/Day-06/a9086.htm.
