This regulation establishes an exemption from the requirement of a tolerance for residues of methyl poly(oxyethylene)C<INF>8</INF>- C<INF>18</INF> alkylammonium chlorides where the poly(oxyethylene) content is n=2-15 and where C<INF>8</INF>-C<INF>18</INF> alkyl is linear and may be saturated or unsaturated, herein referred to in this document as methyl poly(oxyethylene)C<INF>8</INF>-C<INF>18</INF> alkylammonium chlorides (MPOACs), when used as an inert ingredient in pesticide formulations for pre-harvest uses under 40 CFR 180.920 at a maximum of 10% by weight in herbicide formulations and 5% by weight in all other formulations. The Joint Inerts Task Force (JITF), Cluster Support Team (CST No. 7), 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 MPOACs.
