Air Quality Analysis Handbook

SCAQMD is in the process of developing an "Air Quality Analysis Guidance Handbook" (Handbook) to replace the CEQA Air Quality Handbook approved by the AQMD Governing Board in 1993.  The 1993 CEQA Air Quality Handbook is still available but not online. To obtain a hardcopy of the 1993 Handbook, contact SCAQMD's Subscription Services at (909) 396-3720. In addition, there are sections of the 1993 Handbook that are obsolete. A description of the obsolete sections can be obtained from CEQA Air Quality Handbook.
