This regulation establishes an exemption from the requirement of a tolerance for residues of deoxyribonucleic acid sequences consisting solely of adenine, cytosine, guanine, and thymine, of 300 or fewer base pairs, and which do not contain start codons or regulatory sequences necessary for the initiation of transcription or translation when used as an inert ingredient (product identifier) in pesticide formulations applied to growing crops and to raw agricultural commodities after harvest at a concentration not to exceed 1.0 parts per million (ppm). InvisiDex Inc. 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 deoxyribonucleic acid that satisfy the terms of the exemption.
