Title 30 › CHAPTER 3A — LEASES AND PROSPECTING PERMITS › SUBCHAPTER II — COAL › § 209
The Secretary of the Interior may waive, suspend, or lower rent or minimum royalties, or cut the royalty for all or part of a lease, when doing so will help develop resources or when the lease cannot be operated under its current terms. At the leaseholder’s request, the Secretary must review royalty rates before commercial operations start on combined hydrocarbon leases in special tar sand areas. "Tar sand" means rock (not coal, oil shale, or gilsonite) that has a hydrocarbon with a gas-free viscosity over 10,000 centipoise at original reservoir temperature, or rock that is mined or quarried for hydrocarbons. If the Secretary orders or agrees to suspend operations to conserve resources, rental and minimum royalty payments stop during the suspension and the lease is extended by that suspension period. The rule applies to all oil and gas leases under this chapter, including those in unit or cooperative development, but it does not allow waiving, suspending, or reducing advance royalties.
