EPA Publishes 40 Candidate Chemicals for High and Low Prioritization under the Toxic Substance Control Act

On March 21, 2019, the Environmental Protection Agency (EPA) published a notice regarding its initiation of the prioritization process for 20 chemical substances as candidates for designation as High Priority Substances for risk evaluation and 20 chemical substances as candidates for designation as Low Priority Substances for risk evaluation. The amended Toxic Substance Control Act requires EPA to make these designations. A High Priority designation means the agency determined that the chemical substance may present an unreasonable risk of injury to health or the environment because of a potential hazard and a potential route of exposure under the conditions of use, including an unreasonable exposure to workers and other susceptible populations. A Low Priority designation means that EPA determined that the chemical substance does not meet the statutory criteria for a designation as a High Priority chemical.

The list of all the candidates can be accessed here. EPA is seeking information relevant for each chemical, such as hazard, exposure, uses, production size, etc. Each chemical has its own docket which can be found here. The comment period is open until June 19, 2019.
