On April 25, 2019, EPA issued a proposed rule that would amend the TSCA Section 8(a) Chemical Data Reporting (CDR) requirements and the TSCA Section 8(a) size standards for small manufacturers. The current CDR rule requires manufacturers (including importers) of certain chemical substances listed on the TSCA Inventory to report data on chemical manufacturing, processing, and use every four years. EPA is proposing several changes to the CDR rule to make regulatory updates to align with new statutory requirements of TSCA, improve the CDR data collected as necessary to support the implementation of TSCA, and potentially reduce the burden for certain CDR reporters. Proposed updates to the definition for small manufacturers, including a new definition for small governments, are being made in accordance with TSCA Section 8(a)(3)(C) and impact certain reporting and recordkeeping requirements. Overall, according to EPA, the regulatory modifications may better address EPA and public information needs by providing additional information that is currently not collected; improve the usability and reliability of the reported data; and ensure that data are available in a timely manner. Comments are due by June 24, 2019.
