40 C.F.R. § 164.130
EPA has determined that any application under section 3 or section 18 of the Act to allow use of a pesticide at a site and on a pest for which registration has been finally cancelled or suspended by the Administrator constitutes a petition for reconsideration of such order. Because of the extensive notice and hearing opportunities mandated by FIFRA and the Administrative Procedures Act before a final cancellation or suspension order may be issued, EPA has determined that such orders may not be reversed or modified without affording interested parties-who may in fact have participated in lengthy cancellation proceedings-similar notice and hearing opportunities. The procedures set forth in this subpart D shall govern all such applications.
