This summary covers the EPA's final rule regarding a polymer exemption in pesticide formulations: - Government Buyer: - Environmental Protection Agency (EPA) - Office of Pesticide Programs, Registration Division - OEMs and Vendors Mentioned: - Covestro LLC (represented by ChemReg Compliance Solutions LLC) - Products/Services Requested: - No procurement of products or services; the rule establishes an exemption for a specific polymer - Polymer details: - Name: Hexanedioic acid, polymer with sodium 2-[(2-aminoethyl)amino]ethanesulfonate (1:1), 1,6-diisocyanatohexane, 2,2-dimethyl-1,3-propanediol, 1,2-ethanediamine, and 1,6-hexanediol - CAS Number: 67815-81-0 - Minimum number average molecular weight: 64,900 Daltons - Use: Inert ingredient in pesticide chemical formulations - Unique or Notable Requirements: - The EPA determined the polymer meets criteria for low-risk polymers - No tolerance (maximum residue level) is required for this substance in food or feed commodities - The exemption was petitioned by ChemReg Compliance Solutions LLC on behalf of Covestro LLC - No products or services are being procured or awarded; this is a regulatory action, not a solicitation - Relevant Locations: - Environmental Protection Agency, 1200 Pennsylvania Ave. NW, Washington, DC 20460-0001 (regulatory office) - Statistical Area 630, Gulf of Alaska (mentioned in a separate NMFS action, not related to the EPA rule)

Description

This final rule by the Environmental Protection Agency (EPA) establishes an exemption from the requirement of a tolerance for residues of a specific polymer compound when used as an inert ingredient in pesticide chemical formulations. The polymer, identified by CAS Reg. No. 67815-81-0, was petitioned for exemption by ChemReg Compliance Solutions LLC on behalf of Covestro LLC. The regulation eliminates the need to set a maximum permissible residue level for this substance on food or feed commodities, based on EPA's assessment that the polymer meets criteria for low-risk polymers and poses no appreciable risk to human health, including infants and children, under reasonably foreseeable exposure scenarios.
