State Law enacted in 1987 (Connelly)State Law enacted in 1987 (Connelly) Facilities that emit >25 tons/yr of criteria pollutants must report emissions in 1989Facilities that emit >25 tons/yr of criteria pollutants must report emissions in 1989 Facilities that emit >10 tons/yr report in 1990Facilities that emit >10 tons/yr report in 1990 Facilities that emit <10 tons/yr report in 1991Facilities that emit <10 tons/yr report in 1991 Approximately 5,000 facilities Statewide have been evaluated under AB 2588Approximately 5,000 facilities Statewide have been evaluated under AB 2588 Currently only 25 facilities are high riskCurrently only 25 facilities are high risk Background of AB 2588 “Hot Spots” Program

Facilities report air toxics emissions from routine operationsFacilities report air toxics emissions from routine operations High priority facilities prepare health risk assessmentsHigh priority facilities prepare health risk assessments Facilities notify public of significant risksFacilities notify public of significant risks Significant-risk facilities reduce risks below significance levelsSignificant-risk facilities reduce risks below significance levels Facility Requirements

7. Facility Reporting and Update Requirements Requires facilities to update their emission inventories every four yearsRequires facilities to update their emission inventories every four years Allows streamlined updates if “no significant change”Allows streamlined updates if “no significant change”
