On May 3, 2019, the U.S. Environmental Protection Agency (EPA) announced it was making final a single correction to the data requirements for antimicrobial pesticide products codified in 40 C.F.R. Part 158, subpart W.  84 Fed. Reg. 18993.  The correction clarifies that the 200 parts-per-billion (ppb) level described in the antimicrobial pesticides data requirements regulations (40 C.F.R. § 158.2230 (d)) “is based on total estimated daily dietary intake for an individual and not on the amount of residue present on a single food,” as EPA states was incorrectly implied by the previous regulatory text.  

EPA initially proposed this change on August 18, 2017, (82 Fed. Reg. 39399) because it agreed to do so in a settlement agreement with the American Chemistry Council (ACC) after ACC filed a petition for review of the 2013 final rule titled “Data Requirements for Antimicrobial Pesticides” (78 Fed. Reg. 26936 (May 8, 2013)) in the U.S. Court of Appeals for the District of Columbia Circuit.  Specifically, EPA agreed to make this correction to “make the language consistent” with the U.S. Food and Drug Administration’s (FDA) policy set forth in FDA’s “Guidance for Industry, Preparation of Food Contact Notifications for Food Contact Substances: Toxicology Recommendations. Final Guidance. April 2002.”  EPA states that the change is intended to “enhance understanding of the data required to support an antimicrobial pesticide registration and does not alter the burden or costs associated with these previously promulgated requirements” and that it is not establishing “any new data requirements or any other revisions (substantive or otherwise) to existing requirements.” 

The final rule will become effective on July 2, 2019.
