Am. Chemistry Council v. Off. of Environ. Health Hazard AssessmentAnnotate this Case
Proposition 65 was enacted by the voters to protect the people of California and its water supply from harmful chemicals. Proposition 65 required the Governor to publish, at least annually, a list of chemicals known to the state to cause cancer or reproductive toxicity. Proposition 65 added Health and Safety Code section 25249.8, which provided the listing obligations and sets forth four independent “listing mechanisms” by which a chemical could be listed, including the “state’s qualified expert” listing mechanism and the “authoritative body” listing mechanism. At issue in this case was whether the decision by the Office of Environmental Health Hazard Assessment (OEHHA) to list Bisphenol A (BPA) as a chemical known to cause reproductive toxicity under Proposition 65, was an abuse of discretion. BPA is used primarily to coat food and beverage packaging and containers. The American Chemistry Council (ACC) commenced this action seeking to enjoin OEHHA from listing BPA. In an amended complaint, ACC sought a peremptory writ of mandate directing OEHHA not to list BPA. The trial court denied the requested relief. ACC appealed, asserting that OEHHA abused its discretion in: (1) refusing to consider the arguments against listing BPA; (2) concluding that the National Toxicology Program (NTP) formally identified BPA as a reproductive toxicant in the monograph; and (3) determining that NTP concluded that studies in experimental animals indicated that there was sufficient data to establish that an association between adverse reproductive effects in humans and BPA is “biologically plausible” within the meaning of that term as it was used in OEHHA’s own regulation. The Court of Appeal found OEHHA’s position as to biological plausibility was based on, among other things, the presumption that chemicals that cause harm in experimental animals will also cause similar harm in humans in the absence of evidence to the contrary. The Court concluded OEHHA did not abuse its discretion in listing BPA based on the monograph. Therefore, the Court concluded the trial court did not abuse its discretion in denying ACC the relief requested in the amended complaint.
