EPA is extending the public comment period for a manufacturer-requested risk evaluation of four chemical substances as a category, the octahydro-tetramethyl-naphthalenyl-ethanone chemical category (OTNE), to give stakeholders more time to review and comment. The current comment period was set to close on April 5, 2021, and EPA is extending the comment period an additional 30 days. Comments can be submitted to docket EPA-HQ-OPPT-2020-0738 on

EPA welcomes all public comments on this request, particularly on the following:

(*) Any information not included in the manufacturer request that the commenters believe EPA would need to conduct a risk evaluation.

(*) Additional conditions of use the agency is proposing to include in the risk evaluation.

(*) Information on conditions of use not included in the manufacturer request or in the additional conditions of use EPA is proposing to include in the risk evaluation, specifically the inclusion of any additional conditions of use and potentially exposed or susceptible subpopulations.  The agency is in the process of broadly re-examining how it intends to implement these and other provisions of the amended Toxic Substances Control Act (TSCA) including determining how new executive orders will be addressed.  This process would benefit greatly from stakeholder feedback.

After the comment period closes, the agency will review the comments and either grant or deny the request to conduct a risk evaluation within 60 days. If this request is granted, the manufacturers would be responsible for half the cost of the risk evaluation.

On November 20, 2020, EPA received a complete manufacturer request to conduct a risk evaluation for OTNE from International Flavors and Fragrances, Inc. (IFF), Privi Organics USA Corporation (Privi), and DRT America, Inc. (DRT), through the OTNE Consortium. OTNE is used as a fragrance ingredient. The manufacturer-requested risk evaluation of OTNE is the fourth evaluation of this kind to be requested under TSCA.

On December 8, 2020, EPA found this request to be facially complete. Under 40 CFR 702.37(e)(1), no later than 60 business days after receiving a request that EPA has determined to be facially complete, EPA is required to (1) submit for publication in the Federal Register the receipt of the request, (2) open a public docket for the request, and (3) provide no less than 45 calendar days for public comment.
