This regulation establishes an exemption from the requirement of a tolerance for residues of Sodium monoalkyl and dialkyl (C<INF>6</INF>-C<INF>16</INF>) phenoxybenzenedisulfonates and related acids, often known as the "alkyldiphenyl oxide sulfnates", herein referred to in this document as ADPOS, when used as inert ingredients at a maximum of 20% by weight in pesticide formulations for pre-harvest and post-harvest use under 40 CFR 180.910, as well as for application to animals under 40 CFR 180.930. Dow AgroSciences, LLC, 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 ADPOS.
