The U.S. Environmental Protection Agency (EPA) will hold two virtual public meetings, on September 30 and October 1, 2024, to provide information regarding existing chemical pre-prioritization and prioritization activities under the Toxic Substances Control Act (TSCA). 89 Fed. Reg. 68894. EPA states in its August 28, 2024, notice that “[t]he purpose of prioritization is to designate a chemical substance as being either high priority for immediate further risk evaluation, or low priority, for which risk evaluation is not warranted at the time.” EPA notes that although the webinars will take place on two separate days, it will present identical content at each meeting. During the webinars, EPA will explain the prioritization process and provide an overview of information that it may use to inform the considerations that ultimately support a high- or low-priority substance designation, such as information on conditions of use and health effects resulting from exposure to the chemicals of interest. In addition, EPA will present the list of candidate chemical substances currently being considered for future prioritization actions for stakeholders to comment on the information available that EPA may use to determine which chemical substances may undergo prioritization in the near term. Registrations are due September 25, 2024, to receive the webcast meeting link and audio teleconference information before the meeting and to make oral comments during the meeting. Requests for special accommodations are due September 13, 2024, to allow EPA time to process the requests before the meeting. Following the public webinars, written comments may be submitted during a 30-day public comment period that will open following the second public webinar on October 1, 2024.
