The Environmental Protection Agency (EPA) published a final transportation conformity rule for the new air quality standards on July 1, 2004 (69 FR 40004). The final rule describes in general terms how conformity will apply to new nonattainment and maintenance areas under the 8-hour ozone and PM2.5 standards, and how nonattainment areas for the 8-hour ozone standard will use existing adequate or approved motor vehicle emissions budgets ('budgets') in state implementation plans (SIPs) prepared for the 1-hour ozone standard. The transportation conformity rule (40 CFR part 93) outlines the procedures for determining whether federally funded or approved highway and transit projects are consistent with ('conform' to) state air quality goals. Both EPA and the U.S. Department of Transportation (DOT) agree it is necessary to provide additional guidance for conformity implementation to accompany the final rule. EPA is issuing this guidance to clarify how emissions analyses that support them are completed in existing and new nonattainment and maintenance areas, particularly those where multiple agencies or states are involved.
