Air Toxics Program
Prioritization
After a facility’s Plan and Report have been approved, the District is required to prioritize the facility to determine its status within the AB 2588 program. In establishing priorities, the air Districts considers the potency, toxicity, quantity, and volume of hazardous materials released from the facility, the proximity of the facility to potential receptors, and any other factors that determined to pose a significant health risk to nearby receptors. The District uses the prioritization methodology outlined in the California Air Pollution Control Officers Association (CAPCOA) Facility Prioritization Guidelines to prioritize facilities under AB 2588. A facility’s priority status is determined using the prioritization thresholds listed in District Policy APR 1906, as identified in the table below.| Prioritization Thresholds | Priority Category | Category Requirements |
|---|---|---|
| ≤1 | Low Priority | Facility is conditionally exempt from further AB 2588 requirements |
| >1 and ≤10 | Intermediate Priority | Facility is required to provide an update summary on a quadrennial basis |
| >10 | High Priority | Facility is required to perform a Health Risk Assessment |
