When do I use the screening tables in Chapter 6 of the CEQA Air Quality Handbook (SCAQMD, 1993)?
The screening tables should no longer be used under any circumstances because they are based on obsolete mobile source emission factors and trip generation data. The reader should use the methodologies in the Appendix to Chapter 9 of the CEQA Air Quality Handbook or use a land use model, such as URBEMIS. Other air quality analysis methodologies not in the CEQA Air Quality Handbook are acceptable as long as they are well documented, including source(s), assumptions, equations used, calculations, etc.
