What the agency says

This regulation establishes an exemption from the requirement of a tolerance for residues of l-arginine (CAS Reg. No. 74-79-3) when used as an inert ingredient (protein stabilizer) on greenhouse pre- bloom cucumbers at a maximum concentration of <=1%. D. O'Shaughnessy Consulting, Inc. on behalf of A&L Biological 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 l-arginine, when used in accordance with the terms of those exemptions.
