## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of carboxymethyl guar gum sodium salt (CAS Reg. No. 39346-76-4) and carboxymethyl-hydroxypropyl guar (CAS Reg. No. 68130-15-4); when used as an inert ingredient (thicker/drift reduction agent) in pesticide formulations applied to growing crops. SciReg Inc., on behalf of Rhodia Inc., 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 carboxymethyl guar gum sodium salt and carboxymethyl- hydroxypropyl guar.
