The report presents instructions on the Crosswalk/Air Toxic Emission Factor data management system (XATEF). The system was designed to allow rapid identification and cross-referencing of toxic air pollutant/emission source associations and to provide corresponding emission factors for these associations as available. The system contains Standard Industrial Classification (SIC) code/Source Category Code (SCC)/pollutant cross-references found in Toxic Air Pollutant/Source Crosswalk - A Screening Tool For Locating Possible Sources Emitting Toxic Air Substances, Second Edition, EPA-450/2-89-017; and air toxic emission factors compiled in Toxic Air Pollutant Emission Factors - A Compilation For Selected Air Toxic Compounds And Sources, Second Edition, EPA-450/2-90-011. The program has modules that allow users to search and download data to printers or files. The purpose of the report is to document the usage of the system. EPA is making available the system and data to agency users on one high density (1.2 MB) diskette.
