(1) One percent or more of the mixture or product.
(2) Two percent of the mixture or product if the hazardous substance exists as an impurity in the mixture.
(3) One-tenth of 1 percent of the mixture or product if the hazardous substance in the mixture or product is designated as a carcinogen pursuant to the Occupational Carcinogens Control Act of 1976 (Ch. 2 (commencing with Section 24200), Div. 20, H.& S.C.) or the federal Hazard Communication Standard (29 C.F.R. Sec. 1910.1200).
The director may, by regulation, raise the concentration requirement for a hazardous substance which the director finds is not hazardous at the threshold levels; and, lower the concentration requirement for a hazardous substance for which there is valid and substantial evidence that the substance is extraordinarily hazardous.
(b) The manufacturer of a hazardous substance shall notify the director of any valid evidence which indicates that the concentration requirement for a hazardous substance established pursuant to subdivision (a) is higher than what is necessary to protect employees who work with, or may be exposed to, the substance.
