          - [EPA-HQ-OPPT-2011-0941; FRL-9979-23]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

This action is a notification that additional data has been added to the docket for the proposal to amend the significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for oxazolidine, 3,3′-methylenebis [5-methyl-. This action also reopens the comment period for an additional 30 days for public comments based on the additional data added to the docket. The proposal would amend the SNUR to allow certain new uses reported in the significant new use notice (SNUN) without requiring additional SNUNs and make the lack of certain worker protections a new use.

# SUPPLEMENTARY INFORMATION:

## I. General Information

### A. Does this action apply to me?

You may be potentially affected by this action if you manufacture, process, or use the chemical substance contained in this rule. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers determine whether this document applies to them. Potentially affected entities may include:
    - Manufacturers or processors of the chemical substance (NAICS codes 325 and 324110), e.g.,                      chemical manufacturing and petroleum refineries.                

                    This action may also affect certain entities through pre-existing import certification and export notification rules under TSCA. Chemical importers are subject to the TSCA section 13 (15 U.S.C. 2612) import certification requirements promulgated at 19 CFR 12.118 through 12.127 and 19 CFR 127.28. Chemical importers must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA. Importers of chemicals subject to a SNUR must certify their compliance with the SNUR requirements. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. In addition, any persons who export or intend to export a chemical substance that is the subject of a proposed or final SNUR are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see § 721.20), and must comply with the export notification requirements in 40 CFR part 707, subpart D.                          ( print page 34820)    

### B. What should I consider as I prepare my comments for EPA?

                    1.                     *Submitting CBI.*                     Do not submit this information to EPA through                     *regulations.gov*                     or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.                

                    2.                     *Tips for preparing your comments.*                     When preparing and submitting your comments, see the commenting tips at                     *http://www.epa.gov/​dockets/​comments.html*.                

## II. What action is the agency taking?

On February 8, 2018 (83 FR 5598) (FRL-9973-02), document, EPA proposed to amend the SNUR under section 5(a)(2) of TSCA) for oxazolidine, 3,3′-methylenebis [5-methyl- (40 CFR 721.10461), which was the subject of a premanufacture notice (PMN) and a significant new use notice (SNUN). The proposal would amend the SNUR to allow certain new uses reported in the SNUN without requiring additional SNUNs and make the lack of certain worker protections a new use.

In response to public comments on the proposed SNUR, EPA has added additional information to the docket that further explains EPA's risk assessment and includes additional data used in the assessment. EPA is hereby reopening the comment period for 30 days to allow interested parties to consider the data and submit any additional comments.

                    To submit comments, or access the docket, please follow the detailed instructions provided under                     **ADDRESSES**                    . If you have questions, consult the technical person listed under                     **FOR FURTHER INFORMATION CONTACT**                    .
