EPA Updates Small Manufacturer Definition, Reducing Reporting Burden for Certain Stakeholders

For Release: May 12, 2020

EPA is updating the definition of small manufacturers, including a new definition of what is considered a small government, used to determine reporting and recordkeeping requirements under the Toxic Substances Control Act (TSCA). The updated definitions will reduce reporting burdens on chemical manufacturers and small governments while maintaining the agency's ability to receive the information it needs to understand exposure to chemical substances manufactured in the United Sates.

These updated definitions apply to the current Chemical Date Reporting (CDR) rule reporting period, which will begin June 1, 2020, and impact certain reporting and recordkeeping requirements for TSCA section 8(a) rules. This action finalizes the amendments proposed last year and is based on 2018 dollars to ensure that the definition is as up-to-date as possible at the time of finalization.

EPA is also finalizing a technical correction at 40 CFR 704.104 for Hexafluoropropylene oxide and an update to the current small manufacturer definition in the Preliminary Assessment Information Rule (PAIR) rule.
