Thirty-five years of experience implementing and enforcing the Toxic Substances Control Act (TSCA) have demonstrated the strengths and weaknesses of the law and led many to propose legislative changes to TSCA's core provisions. The basic structure of the Toxic Substances Control Act (TSCA) of 1976 has never been amended, but recent legal, scientific, and technological changes are prompting some policy makers to re-examine the law. This book summarises the Toxic Substances Control Act (TSCA) and the major regulatory programs dealing with chemical production and distribution in U. S. commerce.
