Consolidated Table of OEHHA / ARB Approved Risk Assessment Health Values

The Consolidated Table of OEHHA / ARB Approved Risk Assessment Health Values is a quick look-up table of all cancer potency values and noncancer acute, 8-hour, and chronic Reference Exposure Levels (RELs) that are available for use in the AB 2588 Air Toxics "Hot Spots" Program.  The most current acute and chronic health values should be used for the development of a facility health risk assessment.  For more information on the OEHHA Guidelines, see the OEHHA website.  Users of this table are advised to monitor the OEHHA website for any updates to the health values.  If you have any questions, please call the Emission Assessment Branch of the Stationary Source Division at (916) 322-1617 or send email in care of YanPing Zuo.

All tables are in Adobe Acrobat format.
