Under the Air Toxics “Hot Spots” Information and Assessment Act, the operator of a facility must provide notice to all exposed persons if, in the judgment of the South Coast AQMD, the facility’s health risks assessment indicates there is a significant health risk associated with air toxic emissions from the facility. The South Coast AQMD public notification thresholds are as follows:
-
Cancer risk > 10 in one million, or
-
Acute hazard index (HI) > 1.0, or
-
Chronic HI > 1. 0
The notice is made in accordance with procedures specified by the South Coast AQMD, which are as follows:
-
Identify the impact area, that is, the area above the notification thresholds;
-
Distribute public notice materials to all addresses and to parents of children attending school in the area of impact;
-
