The Environmental Protection Agency (EPA) is proposing new rules for the use of certain chemical substances under the Toxic Substances Control Act (TSCA). These rules, known as Significant New Use Rules (SNURs), require entities to notify EPA at least 90 days before starting activities considered significant new uses of these chemicals. The EPA will then assess these uses for potential risks. The proposed rules aim to ensure new chemical substances are safely manufactured and processed, protecting human health and the environment.
Simple Explanation
The EPA wants to make sure some new chemicals are used safely, so they've made a rule that says companies have to ask for permission before using them in certain ways. This is like asking a teacher if it's okay to do something new in class, just to make sure it's safe for everyone.
