The office is concurrently providing notice of its intent to list vinylidene chloride as known to cause cancer for purposes of Proposition 65.  In the event OEHHA does not list the chemical, this rulemaking will be withdrawn.

The purpose of this regulation is to provide "safe harbor" no significant risk levels for dichloromethane (methylene chloride), trichloroethylene, and vinyl chloride.

This regulation adopts no significant risk levels for: Acrylamide, Allyl Chloride, Aniline, Azobenzene, DDVP (Dichlorvos), Folpet, Furmecyclox, Hydrazine, Hydrazine sulfate, 4,4'-Methylene bis(N,N-dimethyl)­ benzeneamine, N-Nitrosodiethanolamine, N-Nitrosomethylethylamine, Pentachlorophenol, and Hexachlorocyclohexane (alpha, beta, and gamma isomers).  

The purpose of these regulations is to provide some "safe harbor" levels and methodologies, and criteria for exposure assessment, which will assist persons in making certain that their discharges, releases or exposures pose no significant risk or would have no observable effect within the meaning of the Act. Article 7, commencing at section 12701, addresses the determination of whether exposures to carcinogens listed under the Act pose no significant risk within the meaning of the Act. Article 8, commencing at section 12801, addresses the determination of whether exposure to listed reproductive toxins would produce no observable effect within the meaning of the Act. 

This regulation adopts no significant risk levels for Benzyl chloride of 4 micrograms per day and Bromodichloromethane of 5 micrograms per day. 

This proposed regulation adopts a no significant risk level for: Aldrin, Asbestos, Carbon tetrachloride, DDT/DDE/DDD, para-Dichlorobenzene, Dieldrin, 1,4-Dioxane, N-Nitrosodipropylamine, and Urethane.  

This regulation adopts no significant risk levels for: Acrylonitrile, Bis(chloromethyl) ether, 3,3'-Dichlorobenzidine, Epichlorohydrin, Hexachlorobenzene, Hexachlorocyclohexane (technical grade), and Polybrominated biphenyls. 

This regulation adopts "no significant risk" levels for Hexachlorodibenzodioxin (HCDD) of 0.0002 microgram per day and 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) of 0.000005 microgram per day. 

This regulation adopts a no significant risk level for benzene of 7 micrograms per day. 

This regulation adopts "no significant risk" levels in Section 12705, subsection (b), for the following chemicals: Arsenic, Butylated hydroxyanisole, Cadmium, and Chromium (hexavalent compounds).
