Title 30 › Chapter CHAPTER 3A— - LEASES AND PROSPECTING PERMITS › Subchapter SUBCHAPTER II— - COAL › § 209
The Secretary of the Interior can waive, pause, or lower rents or minimum royalties, or cut the royalty rate for a whole lease or just a part of it, when needed to help develop coal, oil, gas, oil shale, gilsonite, phosphate, sodium, potassium, or sulfur, or when a lease can't be run successfully under its current terms. At the leaseholder’s request, the Secretary must review royalty rates before commercial production starts for combined hydrocarbon leases in special tar sand areas. If operations are stopped to conserve resources, any acreage rent or minimum royalty payments stop for that suspension period, and the lease term is extended by that same time. This rule covers all oil and gas leases under the chapter, including unit or cooperative plans. The Secretary may not change advance royalty payments. Tar sand: rock (not coal, oil shale, or gilsonite) that either has hydrocarbon material with gas-free viscosity over 10,000 centipoise at original reservoir temperature, or contains hydrocarbon material that is produced by mining or quarrying.
