On February 8, 2019, the U.S. Environmental Protection Agency (EPA) published in the Federal Register its notice extending the review periods for all Toxic Substances Control Act (TSCA) Section 5 Premanufacture Notices (PMN), Significant New Use Notices (SNUN), Microbial Commercial Activity Notices (MCAN), and exemption notices that were submitted to the Agency under TSCA Section 5 before December 29, 2018, and for which the review period had not expired as of December 29, 2018.  84 Fed. Reg. 2851.  The notice states that EPA requires an extension of the review periods to complete its risk assessments, to examine its regulatory options, and to prepare the necessary documents associated with the relevant determination under TSCA Section 5(a)(3).  The duration of the extension period is a total of 33 days, but the notice states that because the extension is less than 90 days, EPA reserves the right under TSCA Section 5(c) to issue, for good cause, future additional extensions for individual cases up to a total of 90 days.

More information on why EPA has chosen to do this is in our blog item regarding the pre-publication version of this notice “EPA Extends Review Periods for TSCA Section 5 PMNs, SNUNs, MCANs and Exemption Notices Due to Lack of Authorized Funding and Shutdown.”
