This regulation establishes an exemption from the requirement of a tolerance for residues of Alkyl (C<INF>12</INF>-C<INF>16</INF>) dimethyl ammonio acetate, herein referred to in this document as ADAA, when used as an inert ingredient (surfactant) in pesticide formulations for pre-harvest uses under 40 CFR 180.920 or applied to animals under 40 CFR 180.930 at a maxiumum concentration of 20% in pesticide product formulations. Technology Sciences Group, Inc., on behalf of Rhodia, Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of ADAA.
