The Office of Environmental Health Hazard Assessment (OEHHA) of
the California Environmental Protection Agency has added the 8 chemicals
named below to the list
of chemicals known to the State to cause cancer or reproductive
toxicity, for purposes of the Safe Drinking Water and Toxic
Enforcement Act of 1986 (Proposition 65 or the Act). These chemicals
are listed effective November 6, 1998. Metham sodium was included
in the notice of intent to list published on December 5, 1997 in
the California Regulatory Notice Register. The 7 other chemicals
were included in the notice of intent to list published on September
4, 1998 in the California Regulatory Notice Register.
The 8 chemicals are listed pursuant to an administrative mechanism
provided under the Act, based upon a formal identification by an
authoritative body that the chemical causes cancer or reproductive
toxicity. The table below indicates documents in which authoritative
bodies formally identified chemicals as causing cancer or reproductive.
Regulations governing the listing of chemicals under the "authoritative
bodies" mechanism are published in 22 CCR, Section 12306.
The 8 chemicals listed effective November 6, 1998, and the mechanism
under which each is listed are shown below:
