The US Environmental Protection Agency (EPA) has issued Significant New Use Rules (SNURs) for 25 chemicals that were the subject of pre-manufacture notices under the Toxic Substances Control Act (TSCA). As a result, “persons who intend to manufacture, import or process these substances for any activity that is designated as a significant new use to notify the agency at least 90 days beforehand.”
Nine of the 25 chemicals are subject to TSCA section 5(e) “risk-based” consent orders. These are substances whose associated activities have been determined by the agency as potential source of unreasonable risk to human health or the environment. Protective measures that will limit exposures or mitigate the potential unreasonable risk have been required by the orders.
