Who must comply with the “Hot Spots” Act?
The Air Toxics “Hot Spots” Act requires the California Air Resources Board (ARB) to maintain a list of toxic air pollutants that may cause adverse health affects. The list is contained in Appendices A-I and A-II of the ARBs Air Toxic “Hot Spots” Emission Inventory Criteria and Guidelines Regulation (CGR). The list, which is updated annually, contains chemicals that have been shown to cause adverse health effects. A business is subject to the Act if: • The business manufactures, formulates, uses, or releases any listed substance, or any substance that reacts to form a listed substance; or • The business is included in a current list of air toxic sources prepared by the APCD.
