The the 1976 Toxic Substances Control Act, or TSCA, is a broken law and contributes much to the delay of addressing poisons all round us. Part of the TSCA is it requires the EPA to consider economic costs of regulation. At this point, industry can argue that asbestos, cigarettes, or BPA is safe, or the costs of regulation is just too high, thus preventing the EPA from protecting citizens. The cost of balancing cost vs results often results in delay for the EPA in taking action, or taking no action at all.
