Health Risk Assessment

A Health Risk Assessment (HRA) is a technical study that evaluates how toxic emissions are released from a facility, how they disperse throughout the community, and the potential for those toxic pollutants to impact human health. 

Both the South Coast AQMD and the state Office of Environmental Health Hazard Assessment (OEHHA) review HRAs submitted by facilities per the requirements of AB 2588.  Questions regarding health risk assessment methodology, guidelines and other AB 2588 issues should be directed to Tracy Goss at (909) 396-3106 or via email at  Also, risk assessment guidance from OEHHA and the South Coast AQMD is provided in links below.
