The Environmental Protection Agency (EPA) has issued new rules under the Toxic Substances Control Act (TSCA) for certain chemical substances identified in premanufacture notices (PMNs). These rules, known as Significant New Use Rules (SNURs), require companies to notify the EPA 90 days before beginning to manufacture or process these chemicals in ways considered a "significant new use," giving the EPA time to evaluate potential risks. The rules include specific requirements for workplace safety, such as ventilation and protective equipment, as well as guidelines for hazard communication. This regulation aims to prevent risks to human health and the environment before these new uses of chemicals are fully developed or used commercially.
Simple Explanation
The EPA has made new rules that say before people can start using certain chemicals in new ways, they must first tell the EPA so they can check if itβs safe. This helps make sure the new uses wonβt harm people or the planet.
