In 1987, the California legislature adopted the Air Toxics “Hot Spots” Information and Assessment ActLink to external website..  The goals of the Act are to collect emissions data of toxic air contaminants, identify facilities having localized impacts, to determine health risks, and to notify affected individuals.   Exposure to toxic air contaminants may produce various adverse health impacts.

There are seven important components to the program as follows:

1. Emissions Reporting Facilities submit an air toxics inventory through the Annual Emissions Report (AER) Program.
2. Prioritization From the reported toxic emissions, AQMD prioritizes facilities, using a procedure approved by the Governing Board, into three categories: high priority, intermediate priority, and low priority.
3. Risk Assessments Potentially high risk facilities must prepare a health risk assessment.
4. Public Notice If the risk reported in the HRA exceeds specific thresholds, then the facility is required to provide public notice to the affected community.
5. Risk Reduction Facilities with health risks above the action risk levels in Rule 1402 must reduce their risks to the community.
6. Industry-wide Source (IWS) Smaller or “IWS” facilities are identified in California H&SC, Section 44323. 

7. Fees State and local costs of implementing the Act are covered through annual fees.

Forms required by various aspects of the program are available for download.
