In this Denial of Objections Order, EPA is denying the objections submitted by Amvac Chemical Corporation (AMVAC) to a Revocation Order EPA issued in May 2013 under the Federal Food, Drug, and Cosmetic Act (FFDCA) revoking all tolerances for the pesticide difenzoquat. EPA revoked the tolerances, consistent with the terms of a previously issued Data Call-In Order, because no notices of intent to submit the required data were submitted, as directed by that Data Call- In Order. In its objections, AMVAC requested that EPA delay the effective date for revoking the difenzoquat tolerances for 4\1/2\ years to allow for importation of food commodities that will be treated with the pesticide in Canada over the next 2 years. EPA denies AMVAC's objections because AMVAC has not filed a proper objection to the Revocation Order.
