“Hot Spots” Applicability Facilities that emit >10 tons per year of Total Organic Gasses (TOG), Particulate Matter (PM), Nitrogen Oxides (NOx), or Sulfur Oxides (SOx)Facilities that emit >10 tons per year of Total Organic Gasses (TOG), Particulate Matter (PM), Nitrogen Oxides (NOx), or Sulfur Oxides (SOx) Facilities that emit >5 tons/yr of any Federal Hazardous Air Pollutant (HAP)Facilities that emit >5 tons/yr of any Federal Hazardous Air Pollutant (HAP) Facilities that emit <10 tons/yr like gas stations, dry cleaners, hazardous waste incinerators, metal platers using cadmium or chromium, waste water treatment facilities, etc.Facilities that emit <10 tons/yr like gas stations, dry cleaners, hazardous waste incinerators, metal platers using cadmium or chromium, waste water treatment facilities, etc.

OEHHA adopts health values based on scientific reports and exposure dataOEHHA adopts health values based on scientific reports and exposure data ARB identifies facilities that must report, which emissions must be reported, and how they are reported to the local air districtARB identifies facilities that must report, which emissions must be reported, and how they are reported to the local air district Local air districts implement the program (review inventory and risk assessments)Local air districts implement the program (review inventory and risk assessments) “Hot Spots” Process

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

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”
