**SUPPLEMENTARY INFORMATION:**
**I. Notice of the Application for Expansion**
OSHA is providing notice that UL LLC (UL), is applying for an expansion of current recognition as a NRTL. UL requests the addition of one test site to the NRTL scope of recognition.
OSHA recognition of a NRTL signifies that the organization meets the requirements specified in 29 CFR 1910.7. Recognition is an acknowledgment that the organization can perform independent safety testing and certification of the specific products covered within the scope of recognition. Each NRTL's scope of recognition includes (1) the type of products the NRTL may test, with each type specified by the applicable test standard and (2) the recognized site(s) that has/have the technical capability to perform the product-testing and product-certification activities for test standards within the NRTL's scope. Recognition is not a delegation or grant of government authority; however, recognition enables employers to use products approved by the NRTL to meet OSHA standards that require product testing and certification.
The agency processes applications by a NRTL for initial recognition, as well as for an expansion or renewal of recognition, following requirements in Appendix A to 29 CFR 1910.7. This appendix requires that the agency publish two notices in the *Federal Register* in processing an application. In the first notice, OSHA announces the application and provides the preliminary finding. In the second notice, the agency provides the final decision on the application. These notices set forth the NRTL's scope of recognition or modifications of that scope. OSHA maintains an informational web page for each NRTL, including UL, which details that NRTL's scope of recognition. These pages are available from the OSHA website at *http://www.osha.gov/dts/otpca/nrtl/index.html.*
UL currently has fifty-seven facilities (site) recognized by OSHA for product testing and certification, with the headquarters located at: UL LLC, 333 Pfingsten Road, Northbrook, Illinois 60062. A complete list of UL sites recognized by OSHA is available at *https://www.osha.gov/dts/otpca/nrtl/ul.html.*
**II. General Background on the Application**
UL submitted an application, dated October 6, 2023 (OSHA-2009-0025-0077), to expand recognition as a NRTL to include one additional test site located at: 4322 New Energy Way, Auburn Hills, Michigan 48326. OSHA staff performed a review of UL's testing facilities at UL Auburn Hills on February 24-25, 2025, in which assessors found some nonconformances with the requirements of 29 CFR 1910.7. UL has addressed these issues sufficiently, and OSHA staff has preliminarily determined that OSHA should grant the application.
**III. Preliminary Finding on the Application**
UL submitted an acceptable application for expansion of its scope of recognition. OSHA's review of the application file and pertinent documentation preliminarily indicates that UL can meet the requirements prescribed by 29 CFR 1910.7 for expanding its recognition to include one additional test site. This preliminary finding does not constitute an interim or temporary approval of UL's application.
OSHA seeks public comment on this preliminary determination.
**IV. Public Participation**
OSHA welcomes public comment as to whether UL meets the requirements of 29 CFR 1910.7 for expansion of recognition as a NRTL. Comments should consist of pertinent written documents and exhibits.
Commenters needing more time to comment must submit a request in writing, stating the reasons for the request by the due date for comments. OSHA will limit any extension to 10 days unless the requester justifies a longer time period. OSHA may deny a request for an extension if it is not adequately justified.
To review copies of the exhibit identified in this notice, as well as comments submitted to the docket, contact the Docket Office, Occupational Safety and Health Administration, U.S. Department of Labor. These materials also are generally available online at *https://www.regulations.gov* under Docket No. OSHA-2009-0025 (for further information, see the “ *Docket* ” heading in the section of this notice titled *ADDRESSES* ).
OSHA staff will review all comments to the docket submitted in a timely manner. After addressing the issues raised by these comments, staff will make a recommendation to the Assistant Secretary of Labor for Occupational Safety and Health on whether to grant UL's application for expansion of the scope of recognition. The Assistant Secretary will make the final decision on granting the application. In making this decision, the Assistant Secretary may undertake other proceedings prescribed in Appendix A to 29 CFR 1910.7.
OSHA will publish a public notice of the final decision in the *Federal Register* .
