Key takeaway
What This Development Means
The Environmental Protection Agency (EPA) has proposed updates to the Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA) for 17 chemical substances, including fluoroalkyl compounds and specific polymers. These updates would require manufacturers, importers, and processors to notify the EPA at least 90 days before engaging in significant new uses, allowing the agency to assess and manage potential risks. The proposal, published on 29 November 2024, aligns with EPA's efforts to regulate persistent and toxic substances like PFAS. Public comments are open until 30 December 2024.
What Are Fluoroalkyl Compounds and Polymers, and Why Are They Regulated by the EPA?
Fluoroalkyl compounds and polymers, such as fluoroalkylacrylate copolymers and fluoroalkyl acrylates, are chemical substances known for their durability and water-resistant properties. The EPA is proposing new Significant New Use Rules (SNURs) to regulate these substances due to their potential persistence in the environment and toxic effects, ensuring proper risk assessments are conducted before new uses.
Why Is the EPA Proposing New Rules for Fluoroalkylacrylate Copolymers?
The EPA's proposed rules for fluoroalkylacrylate copolymers aim to manage risks associated with their manufacturing, importation, or processing. These substances, part of the PFAS chemical family, are being regulated to prevent environmental persistence and potential health hazards. The new rules require a 90-day notification to the EPA for any significant new uses.
The Environmental Protection Agency (EPA) has proposed updates to Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA) for 17 chemical substances, including certain polymers and fluoroalkyl compounds. Published on 29 November 2024, the proposed changes aim to mandate pre-manufacture notifications for any new uses, ensuring thorough risk assessments are conducted before such chemicals are introduced into manufacturing, importation, or processing.
What The Proposal Entails
The EPA’s proposal includes requiring manufacturers, importers, or processors of these chemicals to notify the agency at least 90 days before commencing significant new uses. The agency will evaluate potential risks to human health and the environment under the stipulated conditions. If finalised, the proposed rules would apply across industries that produce or process these substances, as identified by specific North American Industry Classification System (NAICS) codes.
Notable Chemicals Affected
The list of affected substances includes generically identified polymers such as fluoroalkylacrylate copolymers and fluoroalkyl acrylates. Some are noted for their potential persistence, bioaccumulative characteristics, and toxic properties.
These SNURs align with EPA’s broader initiative to regulate per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," due to their lasting environmental and health impacts.
Economic Impact And Compliance Costs
The EPA estimates compliance costs for submitting a Significant New Use Notice (SNUN) at $45,000 for large businesses and $14,500 for small businesses, including user fees and submission costs. Export notifications under TSCA Section 12(b) could add further compliance expenses. Despite these costs, the EPA asserts that the proposal will not have a significant economic impact on small businesses or local governments.
Public Participation
The EPA invites public comments on the proposed rules until 30 December 2024. Stakeholders are urged to provide input through the official federal regulations portal, ensuring that their views on economic, environmental, and procedural aspects are considered.
