. (a) For the purposes of this chapter, a hazardous substance
is present in any mixture or product if it is present in any of the
following concentrations:
(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.
