EPA proposed a significant new use rule (SNUR) on July 11, 2011, for 14 glymes or dimethoxyethane. Issued under section 5(a)(2) of the Toxic Substances Control Act (TSCA), the SNUR would require persons who intend to manufacture, import, or process these chemicals for an activity that is designated as a significant new use by the proposed rule to notify EPA at least 90 days before commencing that activity. This notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.
