This regulation establishes an exemption from the requirement of a tolerance for residues of aspartic acid, N-(1,2-dicarboxyethyl)-, tetrasodium salt (CAS Reg. No. 144538-83-0) when used as an inert ingredient in antimicrobial pesticide products for which, when ready for use, the end-use concentration does not exceed 5,000 parts per million (ppm) of aspartic acid, N-(1,2-dicarboxyethyl)-, tetrasodium salt. Lanxess 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 aspartic acid, N-(1,2-dicarboxyethyl)-, tetrasodium salt, when used in accordance with the terms of the exemption.
