In this order, EPA denies objections to an order denying a petition requesting the modification or revocation of the pesticide tolerances for alachlor, chlorothalonil, and metribuzin, established under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA). The petition was filed on December 17, 2004, by the States of New York, California, Connecticut, and Massachusetts. The petitioners claimed that EPA had improperly removed an additional safety factor for the protection of infants and children from the risk assessments for these pesticide tolerances and that inclusion of this safety factor rendered the tolerances unsafe. EPA issued an order denying that petition, in part, on August 2, 2006. On October 2, 2006, New York, Connecticut, and Massachusetts filed objections to EPA's denial order.
