## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of D-glucurono-6-deoxy-L-manno-D-glucan, acetate, calcium magnesium potassium sodium salt (diutan gum) Chemical Abstract Service Registration Number ((CAS Reg. No.) 595585-15-2) when used as an inert ingredient stabilizer/suspension agent applied to crops pre- and post-harvest and to food contact surfaces. Keller and Heckman on behalf of CP Kelco U.S., 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 D-glucurono-6-deoxy-L-manno-D-glucan, acetate, calcium magnesium potassium sodium salt (diutan gum).
