The U.S. Environmenatal Protection Agency has made certain amendments to the Toxic Substance Control Act (TSCA) relating to the section 12(b) export notification requirements. The first change involves the notification frequency. The current annual notification has been changed to a one-time notification for a chemical on which the EPA has taken action. This rule also establishes de minimis concentrations for mixtures under which notification is no longer required. This threshold is generally set at 1% unless the subject chemical is a known or potential human carcinogen. For these carcinogens a threshold of 0.1% will be established under this regulation. PCB's will now be regulated at or above 50 parts per million (ppm). These changes will be effective January 16, 2007.
