U.S. EPA Draft Risk Evaluation Under the Toxic Substances Control Act

The Association of California Water Agencies (ACWA) appreciates the opportunity to provide comments on the U.S. Environmental Protection Agency's (EPA) draft risk evaluation under the Toxic Substances Control Act (TSCA) for di-isononyl phthalate (DINP) (1,2-Benzene- dicarboxylic acid, 1,2- diisononyl ester) (CASRN 28553-12-0). ACWA shares EPA's goal to protect public health while ensuring a safe and reliable water supply. EPA should carefully consider additional information within the context of water supply before making a final determination as to whether DINP poses unreasonable risk and provide clear guidance on safe water supply piping alternatives if a final risk evaluation determines DINP poses unreasonable risk.
