The Environmental Protection Agency (EPA) has announced it is taking another small step increasing transparency by providing free access to a key database that lists every chemical in commerce. Well…almost every chemical. Of the more than 84,000 chemicals on the Toxic Substances Control Act (TSCA) Chemical Substance Inventory, the identities of almost 17,000 are kept secret because the manufacturers allege the information is confidential business information (CBI). Such CBI claims are widely abused by manufacturers, and with the EPA's acquiescence, large amounts of information are inappropriately withheld from the public.
