States Push to Curb Business Confidentiality Claims for Chemicals

"Federal law forces companies to provide detailed information to U.S. EPA about the toxicity of the chemicals they use.

But there is a catch. The same law -- the 1976 Toxic Substances Control Act, or TSCA -- prohibits the agency from sharing that information with the public or even with state and local authorities.

States are demanding that the law be changed."
