Comment Letter: U.S. EPA Proposed High-Priority Substance Designations

The Association of California Water Agencies (ACWA) appreciates the opportunity to provide comments on the U.S. Environmental Protection Agency’s (EPA) proposal to designate vinyl chloride (CASRN 75- 01-4) as a High-Priority Substance for risk evaluation under the Toxic Substances Control Act (TSCA). ACWA shares EPA’s goal to protect public health while ensuring a safe and reliable water supply. When deciding whether to designate vinyl chloride as a High-Priority Substance, EPA should consider the potential impacts on states and public water agencies including compliance efforts, infrastructure upgrades, and associated costs.
