These SNURs would require persons who intend to manufacture or process any of these chemical substances for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity. The Agency will take comment on the SNURs until November 28, 2016.

Because the Agency may need to regulate this new chemical substance, the Agency needs an extension of the review period to further investigate potential risk, examine regulatory options, and prepare the necessary documents, should regulatory action be required. The PMN included information indicating that this chemical is structurally similar to another chemical previously assessed by EPA that identified acute and chronic risks to human health and EPA is concerned that the PMN substance may present similar risks.

October 17, 2013 -- Toxic Substances Control Act Section 5 New Chemical and Significant New Use Notifications: Delay in Processing Due to Lack of Authorized Funding; Extension of Review Periods

Due to a lapse of appropriations and the Agency shutdown, EPA is extending (pursuant to TSCA sections 5(c) and 26(c) and 40 CFR 720.75(c)) the review periods for all TSCA section 5 Premanufacture Notices (PMNs), Significant New Use Notices (SNUNs), Microbial Commercial Activity Notices (MCANs), and exemption notices that were submitted to the Agency under section 5 of the Toxic Substances Control Act (TSCA; 15 U.S.C. section 2604) before October 1, 2013, and for which the review period has not expired as of October 1, 2013.

There is a possibility that the chemical substances submitted for review in these TSCA section 5 notifications may need to be regulated by EPA under TSCA. The Agency requires an extension of the review periods to complete its risk assessments, to examine its regulatory options, and to prepare the necessary documents, should regulatory action be required. Therefore, EPA has determined that good cause exists to extend, under TSCA section 5(c), the review period for each such TSCA section 5 notification.

The duration of this extension period is equivalent to the duration of the shutdown, i.e., equivalent to the number of days accruing from October 1, 2013, and the date on which this shutdown terminated on October 16, 2013, and EPA operations resumed on October 17, 2013, or a total of 16 days.

Also, during the shutdown, new notifications submitted on or after October 1, 2013, through E-PMN/CDX or other methods were not processed. Consequently, the review period for any TSCA section 5 notice submitted during the shutdown did not begin until operations resumed on October 17, 2013. Information on the duration of the furlough can be found on www.opm.gov.
