Chemical Listed Effective March 14, 2003 as Known to the State of California to Cause Cancer: Strong Inorganic Acid Mists Containing Sulfuric Acid

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is adding strong inorganic acid mists containing sulfuric acid to the list of chemicals known to the State to cause cancer for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). The listing of strong inorganic acid mists containing sulfuric acid is effective March 14, 2003.

The listing of strong inorganic acid mists containing sulfuric acid is based on a formal identification by an authoritative body (i.e., the National Toxicology Program ["NTP"]) that this chemical causes cancer. Regulations governing the listing of chemicals under the "authoritative bodies" mechanism are published in Title 22, California Code of Regulations, Section 12306. The reader is directed to the Notice of Intent to List strong inorganic acid mists containing sulfuric acid published in the July 19, 2002, issue of the California Regulatory Notice Register (Register 02, No. 29-Z) for the documentation supporting OEHHA's determination that the criteria for administrative listing have been satisfied for this chemical.

A complete, updated Proposition 65 list is published elsewhere in this issue of the California Regulatory Notice Register. The following table outlines the addition of strong inorganic acid mists containing sulfuric acid to the Proposition 65 chemical list as known to the State to cause cancer:
