Toxic Air Contaminant Identification Reports
This page last reviewed March 15, 2010
Assembly Bill 1807 (AB 1807) (Stats. 1983, Ch. 1047; Health and Safety Code section 39650 et seq., Food and Agriculture Code Section 14021
et seq.), enacted in September 1983, sets forth a procedure for the
identification and control of toxic air contaminants (TAC) in
California. Therefore, the Air Resources Board (ARB or the Board ) is
responsible for the identification and control of toxic
air contaminants, except in their pesticidal use. The
Department of Pesticide Regulation is responsible
for the regulation of toxic air contaminants in their
pesticidal use.
AB 1807 defines a "toxic air contaminant" as an air pollutant which may
cause or contribute to an increase in mortality or an increase
in serious illness, or which may pose a present or potential
hazard to human health (Health and Safety Code
Section 39655a). The ARB prepares identification
reports on candidate substances under consideration for listing as
toxic air contaminants. The reports and summaries
describe the uses of and the extent of emissions in California
resulting in public exposure, together with their
potential health effects.
The links below provide access to individual reports in PDF. The reports are also available in hard copy. If you have questions, or wish to receive a hard
copy, please call the ARB Air Quality Measures Branch at (916) 322-7072.
