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.

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.
