Two lawsuits aim to stop US federal regulators and industry from "illegally" hiding basic information about toxic chemicals used in consumer products. Companies often claim that toxic chemicals' health and safety data, and even their names, are "confidential business information" (CBI) because making the data public could damage their bottom line. The US Environmental Protection Agency frequently allows industry to use the tactic, which makes it virtually impossible for public health researchers to quickly learn about dangerous chemicals. It also bars most EPA staff and state regulators from accessing the information and criminal charges could be brought against those who do. That leaves regulators attempting to protect the public without essential information for some chemicals and in effect creates a "shadow regulatory government" in the EPA, said Tim Whitehouse, a former EPA attorney who is now director of Public Employees for Environmental Responsibility (Peer), a plaintiff in one of the suits. The ... suit alleges the EPA has narrowed Congress's definitions of what should be made public. The EPA is also withholding chemical safety test results that show health risks to the public or environment. Separately, Peer is suing the EPA for hiding health and safety data for chemicals made by Inhance Technologies, which produces plastic containers found to leach dangerous levels of PFOA, a highly toxic compound, into the containers' contents.
