## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of di-n-butyl carbonate (CAS Reg. No. 542- 52-9) when used as an inert ingredient (solvent) in pesticide formulations applied to growing crops, raw agricultural commodities after harvest, and animals, and when used as an inert ingredient in antimicrobial pesticide formulations in food-contact surfaces sanitizer products at a maximum level in the end-use concentration of 15,000 ppm (1.5%). Exponent Inc., on behalf of Huntsman Corp., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of di-n-butyl carbonate.
