## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of polyethyleneimine when used as an inert ingredient in a pesticide chemical formulation on growing crops and 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. This regulation eliminates the need to establish a maximum permissible level for residues of polyethyleneimine when used as an inert in pesticide formulations applied to growing crops and raw agricultural commodities after harvest.
