EPA Opens Registration for Part Two of Its Webinar Series on Reviewing MMOs
The U.S. Environmental Protection Agency (EPA) has opened registration for the second of its 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). The webinar, which will be held March 30, 2023, 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 kickoff webinar, held in November 2022, provided a broad overview of the approach and answered stakeholder questions. A summary of the first webinar is available in our November 23, 2022, memorandum.
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. As reported in our October 11, 2022, memorandum, EPA announced an innovative effort to help make its review of new MMOs, including new and modified CAMs, more efficient. According to EPA, 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.
