## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of fatty acids, C<INF>16-18</INF> and C<INF>18</INF>-unsatd., esters with polyethylene glycol mono-Me ether (CAS Reg. No. 518299-31-5) when used as an inert ingredient (surfactant and related adjuvant of surfactant) on growing crops and raw agricultural commodities pre- and post-harvest limited to 25% by weight in pesticide formulations. Spring Regulatory Sciences on behalf of Sasol Chemicals (USA) LLC 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 fatty acids, C<INF>16-18</INF> and C<INF>18</INF>- unsatd., esters with polyethylene glycol mono-Me ether, when used in accordance with the terms of this exemption.
