(petitioner for the regulatory change) - No procurement of products or services is requested; this is a regulatory action - Rule establishes an exemption from tolerance requirements for sodium nitrate (CAS Reg.

Description

This regulation establishes an exemption from the requirement of a tolerance for residues of sodium nitrate when used as an inert ingredient in pesticide formulations applied to raw agricultural commodities post-harvest in sealed warehouses. The exemption applies only when sodium nitrate is used in a fumigant canister that is remotely detonated and released inside a sealed warehouse. The rule responds to a petition by AgroFresh Inc. and eliminates the need to establish a maximum permissible level for sodium nitrate residues under these conditions. It also corrects a typographical error in the chemical identification of d-Alpha tocopherol.
