EPA proposes rules for new chemical substances under TSCA

The Environmental Protection Agency is proposing Significant New Use Rules, or SNURs, for certain chemical substances. These rules would require companies that want to manufacture, process, or import these chemicals for specific uses to notify the EPA at least 90 days before starting those activities.

Why it matters: This action creates an administrative hurdle for companies that want to expand how they use specific chemicals. It does not ban these uses but requires a waiting period and reporting so the EPA can evaluate potential risks before the activity begins. For most businesses, this is a compliance step rather than a total prohibition.

Who it affects

• Chemical manufacturers and processors, particularly those in NAICS codes 325 and 324110
