Toxic Air Pollutant/Source Crosswalk - A Screening Tool for Locating Possible Sources Emitting Toxic Air Pollutants

摘要

The report presents an Air Toxic Pollutant Crosswalk that associates emitting source categories with specific air toxics compounds. This is a qualitative association and does not provide any information about the quantities of pollutants emitted from the source categories. The crosswalk contains pollutant names, CAS numbers, industrial source categories (SIC codes), and emitting source classifications (SCC codes). Appendices C-G of the EPA report, Compiling Air Toxics Emissions Inventory, EPA-450/4-86-010, were updated and expanded to develop the report. In addition, a software system containing the crosswalk was developed for easy access and updating of the data. Use of the system is explained in the EPA report, Toxic Air Pollutant/Source Crosswalk - Information Storage and Retrieval System User's Manual, EPA-450/4-87-023b. EPA is making available the system and data base records to agency users upon request. The purpose of the report is to offer a technical service to air pollution control agencies in performing preliminary assessments of the types and sources of toxic compounds present in an area. The crosswalk helps agencies to identify the potential of pollutants to be emitted from sources in an area.
