A recently published Environmental Protection Agency (EPA) final rulemaking (40 CFR 93.116) established transportation conformity criteria and procedures for identifying transportation projects that must be analyzed for local air quality impacts in PM2.5 and PM10 nonattainment and maintenance areas. A qualitative hot-spot analysis is required for "projects of air quality concern" as defined in EPA's final rule. PM hot-spot analyses assess projects found to be of "air quality concern" through the interagency consultation screening process, in combination with changes in background air quality concentrations, to determine if new or worsened future violations will result from their implementation. This paper presents suggestions for the development and utilization of various tools based on existing studies, computations and data, which can be compiled to form an evidence toolbox for use in qualitative PM hot-spot analyses. The evidence toolbox is designed for use by transportation officials and interagency consultation groups (ICG) in order to demonstrate whether a transportation project may or may not have any adverse affect on future PM emissions.
