EPA and state regulators continue efforts to reform chemicals management regulations under the Toxic Substances Control Act (TSCA), as Congress debates reauthorization of the federal statute. On Dec. 2, 2009, regulators in 13 states issued a statement of principles for reforming TSCA. These include principles focused on manufacturer-provided chemical data reporting; protecting vulnerable populations through new regulations, addressing emerging contaminants, including nano-scale contaminants; and identifying safe alternatives to toxic chemicals in products. EPA has issued a statement of "essential principles" for reforming TSCA to aid Congress as it addresses reauthorization of the federal statute. EPA is seeking increased regulatory authority and tools to target chemicals of concern, and promptly assess and regulate new and existing chemicals.
