The EPA on Monday, Sept. 20, 2010, submitted its final rule in the Federal Register promulgating significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 25 chemical substances which were the subject of premanufacture notices.

One of these chemical substances is subject to a TSCA section 5(e) consent order issued by the EPA. This action requires persons who intend to manufacture, import, or process any of these 25 chemical substances for an activity that is designated as a significant new use by this rule to notify the agency at least 90 days before commencing that activity.

See PE's exclusive table below for an account of the 25 substances.
