On March 30, 2023, the U.S. Environmental Protection Agency’s (EPA) New Chemicals Program (NCP) held the second of a two-part webinar series on EPA’s new standardized process to assess risk and apply mitigation measures, as appropriate, for mixed metal oxides (MMO), including new and modified cathode active materials (CAM). Under the Toxic Substances Control Act (TSCA), EPA reviews new chemical substances before they enter the marketplace to ensure they do not present unreasonable risk to human health or the environment. In October 2022, EPA announced an “innovative effort” to help make its review of new MMOs, including new and modified CAMs, more efficient. The webinar focused on “one of the most time consuming parts of the new chemical review process for MMOs CAMs,” the human health risk assessment. During the webinar, EPA demonstrated a risk calculator tool that it developed. Once the tool is available for stakeholders to use, the submitter will be able to see immediately where mitigation will be required. For more information on the second webinar, please read the full memorandum.
