## I. General Information

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

                    You may be potentially affected by this action if you are a company needing assistance in creating structurally descriptive generic names for chemical substances whose specific chemical identities are claimed confidential, for purposes of protecting the specific chemical identities from disclosure and listing the substances on the TSCA Chemical Substance Inventory. This action may be of particular interest to entities that are regulated under TSCA (                    *e.g.,*                     entities identified under North American Industrial Classification System (NAICS) codes 324, 325, and 324110, among others). Since other entities also may be interested, the Agency has not attempted to describe all the specific entities and corresponding NAICS codes for entities that may be interested in or affected by this action.                

### 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.*

### C. How can I get copies of this document and other related information?

Please review the visitor instructions and additional information about the docket that is available at                     *http://www.epa.gov/​dockets.*                     You also will find this document and the “Guidance for Creating Generic Names for Confidential Chemical Substance Identity Reporting under TSCA” at                     *http://www.epa.gov/​tsca-inventory.*

## II. What is the Agency's authority for this action?

As amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in June 2016, TSCA section 14(c)(4), 15 U.S.C. 2613(c)(4), requires that EPA develop guidance regarding the determination of structurally descriptive generic names provided for chemical substances whose specific chemical identities have been claimed confidential in a TSCA notice. TSCA section 14(c)(1)(C) was amended to require submitters who assert a confidentiality claim for specific chemical identity to include a structurally descriptive generic name for the chemical substance that EPA may disclose to the public. The generic name must be consistent with EPA's guidance, and should describe the chemical structure of the substance as specifically as practicable while protecting those features of the chemical structure that are claimed as confidential and the disclosure of which would be likely to cause substantial harm to the competitive position of the claimant.

## III. What action is the Agency taking?

                    EPA is announcing the availability of the following guidance document: “                    *Guidance for Creating Generic Names for Confidential Chemical Substance Identity Reporting under TSCA.”*                     This guidance document is intended to assist companies in creating structurally descriptive generic names for chemical substances whose specific chemical identities are claimed confidential, for purposes of protecting the specific chemical identities from disclosure while describing the chemical substance as specifically as practicable, and for listing substances on the TSCA Chemical Substance Inventory.                

                    EPA previously published guidance to assist companies in creating structurally descriptive generic names in an appendix to the 1985 publication of the TSCA Inventory (Appendix B, “                    *Generic Names for Confidential Chemical Substance Identities,*                    ” in the “                    *TSCA Inventory, 1985 Edition*                    ”). The new guidance document updates and replaces the 1985 guidance. Consistent with TSCA section 14(c)(1)(C) and 14(c)(4) requirements, the updated guidance document provides more detail and clarity to companies regarding the approach for creating structurally descriptive generic names.                

As a nonbinding guidance document, this updated guidance document is a living document which may be revised periodically and without notice. In addition to seeking comments within the next 60 days, EPA welcomes public input on this guidance document at any time in the future.

Authority:15 U.S.C. 2613(c)(4).

Dated: June 21, 2018.
