🧪EPA Findings on New Chemicals Not Likely to Present Risks
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 April 1, 2025 to April 30, 2025.
