Environmental Protection Agency April 25, 2019 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve a revision to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NOX) from on-road heavy-duty vehicles. We are proposing to approve a local measure to reduce NOX emissions from these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.

EPA is proposing to amend the Toxic Substances Control Act (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 Chemical Substance Inventory (TSCA Inventory) to report data on chemical manufacturing, processing, and use every 4 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 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 for TSCA section 8(a) rules, including CDR. The definitions may reduce burden on chemical manufacturers by increasing the number of manufacturers considered small. Overall, these 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.
