Sodium Nitrate in Pesticide Formulations; Exemption From the Requirement of a Tolerance

Document 2026-11941 is a Final Rule published by the Environmental Protection Agency in the Federal Register on June 15, 2026, with an effective date of June 15, 2026. This regulation establishes an exemption from the requirement of a tolerance for residues of sodium nitrate (CAS Reg. No. 7631-99-4) when used as an inert ingredient (dilutant/oxidizer) in pesticide formulations applied to raw agricultural commodities post-harvest under 40 CFR 180.910, only when used in a fumigant canister that is remotely detonated and released inside a sealed warehouse. AgroFresh 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 sodium nitrate, when used in accordance with the terms of this exemption. This action also corrects a typographical error to the CAS Reg. No. of d-Alpha tocopherol. A digit was inadvertently omitted from the previously listed CAS Reg. No., resulting in a number that is not valid and does not represent any chemical.
