The U.S. Environmental Protection Agency (EPA) published a final rule on February 16, 2024, amending the Toxic Substances Control Act (TSCA) regulations for polymers manufactured under the terms of the polymer exemption by extending the submission deadline for reporting. 89 Fed. Reg. 12248. EPA notes that the regulations require that manufacturers (includes importers) of polymers manufactured under the terms of the exemption submit a report of manufacture or import by January 31 of the year subsequent to initial manufacture. EPA states that on June 7, 2023, it amended the exemption reporting requirement to require that the exemption report and accompanying confidentiality claims be submitted electronically. Because EPA experienced technical difficulties with the launch of the new electronic reporting tool, EPA is extending the reporting period for 2024 from January 31, 2024, to March 31, 2024, to allow manufacturers additional time to submit their reports and accompanying claims to EPA using the electronic reporting tool. The final rule was effective February 16, 2024. More information on EPA’s June 7, 2023, final rule with new and amended requirements concerning the assertion and treatment of confidential business information (CBI) claims for information reported to or otherwise obtained by EPA under TSCA is available in our June 12, 2023, memorandum.
