EPA is promulgating significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 56 chemical substances which were the subject of premanufacture notices (PMNs). Four of these chemical substances are subject to TSCA section 5(e) consent orders issued by EPA. Two of these chemicals are nanomaterials: siloxane modified silica nanoparticles (generic) and siloxane modified alumina nanoparticles (generic). This is the first time SNURs have been promulgated for nanomaterials.
This action requires persons who intend to manufacture, import, or process any of these 56 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.
The effective date of this rule is January 5, 2009 without further notice, unless EPA receives written adverse or critical comments, or notice of intent to submit adverse or critical comments before December 5, 2008. This rule shall be promulgated for purposes of judicial review at 1 p.m. (e.s.t.) on November 19, 2008. If EPA receives written adverse or critical comments, or notice of intent to submit adverse or critical comments, on one or more of these SNURs before December 5, 2008, EPA will withdraw the relevant sections of this direct final rule before its effective date. EPA will then issue a proposed SNUR for the chemical substance(s) on which adverse or critical comments were received, providing a 30-day period for public comment.
