43 C.F.R. § 3200.3
There are many leases and agreements currently in effect, and that will remain in effect, involving Federal geothermal resources leases that specifically refer to the United States Geological Survey, USGS, Minerals Management Service, MMS, or Conservation Division. These leases and agreements may also specifically refer to various officers such as Supervisor, Conservation Manager, Deputy Conservation Manager, Minerals Manager, and Deputy Minerals Manager. Those references must now be read to mean either the Bureau of Land Management or the Minerals Management Service, as appropriate. In addition, many leases and agreements specifically refer to 30 CFR part 270 or a specific section of that part. Effective December 3, 1982, references in such leases and agreements to 30 CFR part 270 should be read as references to this part 3200, which is the successor regulation to 30 CFR part 270.
