Certain New Chemicals or Significant New Uses; Statements of Findings-March 2026

The Toxic Substances Control Act (TSCA) requires EPA to publish in the Federal Register a statement of its findings after its review of certain TSCA submissions when EPA makes a finding that a new chemical substance or significant new use is not likely to present an unreasonable risk of injury to health or the environment. Such statements apply to premanufacture notices (PMNs), microbial commercial activity notices (MCANs), and significant new use notices (SNUNs) submitted to EPA under TSCA. This document presents statements of findings made by EPA on such submissions during the period from March 1, 2026, to March 31, 2026.

Bacillus Thuringiensis Cry1B.34.1, Bacillus Thuringiensis Cry1B.61.1 and Adiantum Trapeziforme var. Braziliense IPD083Cb Proteins; Pesticide Tolerances

This regulation establishes exemptions from the requirement of a tolerance for residues of the Bacillus thuringiensis Cry1B.34.1, Bacillus thuringiensis Cry1B.61.1, and Adiantum trapeziforme var. braziliense IPD083Cb proteins (hereafter Cry1B.34.1, Cry1B.61, and IPD083Cb proteins) in or on all food and feed commodities when used as plant-incorporated protectants (PIP). Pioneer Hi-Bred International Inc. (Pioneer) submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting exemptions from the requirement of a tolerance. This regulation eliminates the need to establish maximum permissible levels for residues of Cry1B.34.1, Cry1B.61, and IPD083Cb proteins when used in accordance with the terms of the exemption.

Significant New Use Rules on Certain Chemical Substances (25-2.5e)

EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification; made an appropriate determination regarding that notification; and taken such actions as required by that determination.
