California Air Toxic "Hot Spots" (AB2588) Program
This site provides background information on Assembly Bill 2588, the Air Toxics "Hot Spots" Information and Assessment Act of 1987, adopted in response to the public's concern about the emissions of toxic air contaminants and their potential adverse health effects. The "Hot Spots" Act requires facilities to report emissions of toxic chemicals to the local air district. The district reviews the emission reports and ranks (prioritizes) facilities for potential to pose significant risk. High priority facilities are required to conduct a detailed health risk assessment (HRA). Those facilities with a significant health risk are required to notify the affected public. Senate Bill 1731 amended the Hot Spots Act in 1992; requiring that facilities with significant health risks prepare risk reduction audits and plans and implement feasible risk reductions.
