IntroductionThe current version of EPA's vehicle emission modeling software is MOBILE 6.2. This model must be used for all regional and project-level analyses. In addition, the screening model CAL3QHC is used to perform project-level analyses for carbon monoxide.Information for Project-Level AnalysisMOBILE 6.2 emission factor files should be obtained from PSRC to ensure consistency with the regional analysis and that the most current settings are used. These settings include vehicle registrations and data based on the Emission Check Program (vehicle Inspection and Maintenance program). Files are generally updated every year. Further asistance on performing project-level analyses can be found in the Guidebook for Conformity.ModelsEPA's MOBILE6 Vehicle Emission Modeling SoftwareCAL3QHC Air Pollution Modeling Software
