## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of pyrrolo[3,4-c]pyrrole-1,4-dione, 3,6- bis(4-chlorophenyl)-2,5-dihydro- when used as an inert ingredient (dye, coloring agent) in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest. BASF Corporation 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 for pyrrolo[3,4-c]pyrrole-1,4-dione, 3,6- bis(4-chlorophenyl)-2,5-dihydro-. This regulation eliminates the need to establish a maximum permissible level for residues of pyrrolo[3,4- c]pyrrole-1,4-dione, 3,6-bis(4-chlorophenyl)-2,5-dihydro- when used in accordance with this exemption.
