Cal. Code Regs. tit. 17 § 70101
The objective of ambient air quality standards is to provide a basis for preventing or abating the effects of air pollution, including effects on health, esthetics and economy. The standards should not be interpreted as permitting, encouraging, or condoning degradation of present air quality in any air basin which now has an air quality superior to that stipulated in the standards. Pollution levels below those shown in the standards should not ordinarily produce the associated effects.
In determining compliance with the standards through air monitoring, the sites and conditions of air sampling should be so chosen as to realistically represent the exposures of people, animals, vegetation and materials.
Ambient air quality standards shall be reviewed and subject to modification whenever substantial pertinent new information becomes available and at least once every five years. To the extent feasible, review of a standard shall be coordinated with the review of any corresponding federal standard by the Environmental Protection Agency.
