The Environmental Protection Agency (EPA) is proposing new rules under the Toxic Substances Control Act (TSCA) for certain chemical substances previously submitted for premanufacture notices. These rules, known as Significant New Use Rules (SNURs), will require any person planning to manufacture or process these chemicals in a way that has been identified as a significant new use to notify the EPA at least 90 days before starting. This allows the EPA to assess the potential risks and decide on any necessary actions before the activity begins. Additionally, the chemicals must not be manufactured or processed for these new uses until they receive EPA approval.
Simple Explanation
The EPA wants to make sure people tell them before making or changing certain chemicals in new ways so they can check if it's safe, like asking for permission before trying something different.
