On April 24, 2018, the U.S. Environmental Protection Agency (EPA) is scheduled to publish a notice in the Federal Register that it will be adding a supplemental analysis, “Supplemental Analysis of Alternative Small Business Size Standard Definitions and their Effect on TSCA User Fee Collection,” to the rulemaking docket for the User Fees for the Administration of the Toxic Substances Control Act (TSCA) proposed rule published on February 26, 2018. EPA will also be extending the comment period for the proposed rule for an additional 30 days “to give interested parties the opportunity to consider this additional analysis and prepare meaningful comments.” Comments will be due within 30 days of publication (by May 24, 2018). The original comment deadline was April 27, 2018.

Regarding the supplemental analysis, EPA states that it “provides additional estimates for the impact of setting the small business definition based on an employee-based threshold.” More information on the proposed rule is available in our February 9, 2018, memorandum “Administrator Pruitt Signs TSCA User Fee Proposal.”
