Legal Status This site displays a prototype of a “Web 2.0” version of the daily
Federal Register. It is not an official legal edition of the Federal
Register, and does not replace the official print version or the official
electronic version on GPO’s govinfo.gov.

The documents posted on this site are XML renditions of published Federal
Register documents. Each document posted on the site includes a link to the
corresponding official PDF file on govinfo.gov. This prototype edition of the
daily Federal Register on FederalRegister.gov will remain an unofficial
informational resource until the Administrative Committee of the Federal
Register (ACFR) issues a regulation granting it official legal status.
For complete information about, and access to, our official publications
and services, go to About the Federal Register on NARA's archives.gov.

The OFR/GPO partnership is committed to presenting accurate and reliable
regulatory information on FederalRegister.gov with the objective of
establishing the XML-based Federal Register as an ACFR-sanctioned
publication in the future. While every effort has been made to ensure that
the material on FederalRegister.gov is accurately displayed, consistent with
the official SGML-based PDF version on govinfo.gov, those relying on it for
legal research should verify their results against an official edition of
the Federal Register. Until the ACFR grants it official status, the XML
rendition of the daily Federal Register on FederalRegister.gov does not
provide legal notice to the public or judicial notice to the courts.

Mine Safety and Health Administration

1. 30 CFR Parts 7, 18, 44, 46, 48, 49, 56, 57, 60, 70, 71, 72, 74, 75, and 90

( printed page 9447)

ACTION:

Final rule; technical amendment.

SUMMARY:

The Mine Safety and Health Administration (MSHA) is amending its published regulations to update the Agency's Headquarters address from Arlington, VA to its new location in Washington, DC.

DATES:

Effective date: February 26, 2026.

FOR FURTHER INFORMATION CONTACT:

Jessica D. Senk, Acting Director, Office of Standards, Regulations, and Variances, MSHA, at Senk.Jessica@dol.gov (email); (202) 693-9440 (voice); or (202) 693-9441 (facsimile). These are not toll-free numbers.

SUPPLEMENTARY INFORMATION:

In Spring 2025, MSHA moved its Headquarters offices from 201 12th Street South, Arlington, VA 22202-5452 to 200 Constitution Avenue NW, Washington, DC 20210. MSHA is amending its regulations to include the Agency's new Headquarters address in Title 30 of the Code of Federal Regulations (CFR), Mineral Resources, Chapter I.

This technical amendment is a procedural “rule” under 5 U.S.C. 551(4), and it is not subject to the notice-and-comment rulemaking requirements in 5 U.S.C. 553. This action also does not constitute a “regulatory action” subject to Executive Order 12866. Accordingly, the regulations in 30 CFR parts 7, 18, 44, 46, 48, 49, 56, 57, 60, 70, 71, 72, 74, 75, and 90 are amended to include the updated address information.
