The required notification initiates EPA’s evaluation of the intended use within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required with that determination. This rule is effective 60 days after publication of the rule in the Federal Register.

February 1, 2019 – TSCA Section 5 New Chemical and Significant New Use Notifications: Delay in Processing Due to Lack of Authorized Funding; Extension of Review Periods

Due to the recent 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 TSCA section 5 (15 U.S.C. section 2604) before December 29, 2018, and for which the review period had not expired as of December 29, 2018. This impacts a total of 581 new chemical notifications.

The duration of this extension period is equivalent to the duration of the time period from December 29, 2018 (i.e., the date on which certain EPA operations shutdown) and the date on which EPA operations for the TSCA New Chemicals Program fully resumed (i.e., January 31, 2019), or a total of 33 days. 

Also, during the shutdown, new notifications submitted on or after December 29, 2018, 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 normal operations resumed on January 31, 2019. This impacts a total of 24 new chemical notifications.

Additional Information regarding this extension can be found in the Federal Register notice.

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.
