Register for Part Two of EPA’s Webinar Series on Reviewing Mixed Metal Oxides

Released on March 9, 2023

Join the U.S. Environmental Protection Agency (EPA) on March 30, 2023, at 1 p.m. EDT for 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 (MMOs), including new and modified cathode active materials (CAMs).

Under the Toxic Substances Control Act (TSCA), EPA reviews all 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 the Agency’s review of new MMOs, including new and modified CAMs, more efficient. MMOs have many electrical applications in batteries and uses as catalysts, adsorbents and in ceramics. Notably, MMOs, including CAMs, are a key component in lithium-ion batteries used in electric vehicles, making them a vital part of clean energy sectors.

This webinar will give an in-depth look into the standardized risk assessment approach, and present various case scenarios and a decision tree for identifying potential hazards and risks. The kick-off webinar, held in November 2022, provided a broad overview of the approach and answered stakeholder questions. Meeting materials are available for those who missed the first webinar.
