EPA is taking direct final action to add a new section to part 180 which lists the pesticide chemicals that are exempt from the requirement of a tolerance when used in food-contact surface sanitizing solutions. The initial list of exempt pesticide chemicals in the new section is duplicated from the Food and Drug Administration's (FDA) regulations in 21 CFR 178.1010. EPA is also changing FDA's naming conventions for some of the chemical substances that were duplicated. Until recently, FDA under the Federal Food, Drug, and Cosmetic Act (FFDCA) section 409, regulated food-contact surface sanitizing solutions. With the amendments to FFDCA by the Food Quality Protection Act (FQPA) of 1996 and by the Antimicrobial Regulation Technical Corrections Act (ARTCA) of 1998, these responsibilities have been restructured. Under FFDCA section 408, EPA will now regulate the pesticide uses of these chemical substances and FDA under FFDCA section 409 will continue to regulate any indirect food additive uses of these chemical substances. Registrants of existing food-contact surface sanitizing solutions that contain chemical substances other than those listed in this direct final rule should identify these chemical substances and support their claim that the chemical substance is generally recognized as safe (GRAS), or permitted by FDA prior sanction, or approval, or subject to a letter of no objection in order to remain exempt from the requirement of a FFDCA section 408 tolerance.
