Mine Safety and Health Administration (MSHA), Department of Labor.
Final rule; technical amendment.
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.
Effective date: February 26, 2026.
Jessica D. Senk, Acting Director, Office of Standards, Regulations, and Variances, MSHA, at [email protected] (email); (202) 693-9440 (voice); or (202) 693-9441 (facsimile). These are not toll-free numbers.
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.
