The Lautenberg Chemical Safety for the 21st Century Act updates which federal law?

• A. Clean Air Act
• B. Toxic Substances Control Act
• C. Safe Drinking Water Act
• D. Federal Insecticide, Fungicide, and Rodenticide Act

Answer: (B)

It updates the Toxic Substances Control Act. The Lautenberg Chemical Safety for the 21st Century Act, enacted in 2016, strengthens how the U.S. handles chemical safety by requiring the EPA to systematically evaluate existing chemicals for safety, establish clear priorities for risk evaluations, and require additional data and testing to fill information gaps. It uses a risk-based framework to determine if a chemical presents an unreasonable risk and, if so, enables regulatory actions to restrict or ban that chemical. It also improves data availability and transparency so safety decisions are better informed. These changes modernize chemical management specifically within TSCA, not the other laws that govern air quality, drinking water, or pesticides.
