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. Facilities that submit HRAs in accordance with these requirements may also do so under the designation as a Potentially High Risk Level Facility. A Potentially High Risk Level Facility is one that has risks that may exceed the Significant Risk Level and is required to reduce risks promptly by submitting an Early Action Reduction Plan and a Risk Reduction Plan (RRP) on expedited timelines.
Questions regarding health risk assessment methodology, guidelines and other AB 2588 issues should be directed to Scott Epstein, Planning and Rules Manager at (909) 396-3754 or via email at [email protected]. Also, links to risk assessment guidance from OEHHA and the South Coast AQMD are provided at the bottom of this page.
The sections below list the recently approved HRAs and related AB 2588 documents, including those for Potentially High Risk Level Facilities. Alternate HRAs are not approved by South Coast AQMD and are not allowable for determining risk levels outlined in Rule 1402.
