WASHINGTON, D.C. - The U.S. EPA is issuing a final rule under the Toxic Substances Control Act (TSCA) requiring manufacturers of 19 high production volume (HPV) chemicals to test the health and environmental effects of the chemicals and submit the data to the agency. This rule is one of a series of actions that EPA is taking to ensure that the agency has the data it needs to adequately review priority chemicals. HPV chemicals are produced in or imported into the United States in quantities of one million pounds or more per year.
