California redefines intentionally added PFAS chemicals in product manufacturing

During a recent Senate Health and Welfare meeting in Vermont, significant changes were proposed regarding the definition of "intentionally added" chemicals in manufacturing, particularly concerning PFAS (per- and polyfluoroalkyl substances). This substantial rewrite aims to clarify how these chemicals are defined and regulated in products.

The revised definition specifies that a chemical is considered "intentionally added" if it serves a specific function during the manufacturing process and is present in the final product. Notably, the addition of PFAS must be known or easily ascertainable by the manufacturer. Importantly, the use of water in the manufacturing process will not classify PFAS as intentionally added if the water comes from a compliant public water system and meets the state's maximum contaminant levels for PFAS.

This change is part of a broader effort to address environmental and health concerns related to PFAS, which have been linked to various health risks. However, the discussion raised questions about what constitutes a "covered product," indicating that further clarification and guidelines may be needed as the legislation progresses.

The implications of these changes are significant for manufacturers and consumers alike, as they seek to navigate the complexities of chemical use in products. As Vermont moves forward with these regulations, stakeholders will be closely monitoring how these definitions will impact manufacturing practices and public health.
