eligible lands

All lands to be leased which are not subject to leasing under paragraphs (2) and (3) of this subsection shall be leased as provided in this paragraph to the highest responsible qualified bidder by competitive bidding under general regulations in units of not more than 2,560 acres, except in Alaska, where units shall be not more than 5,760 acres. Such units shall be as nearly compact as possible. Lease sales shall be conducted by oral bidding, except as provided in subparagraph (C). Lease sales shall be held for each State where eligible lands are available at least quarterly and more frequently if the Secretary of the Interior determines such sales are necessary. For purposes of the previous sentence, the term “eligible lands” means all lands that are subject to leasing under this chapter and are not excluded from leasing by a statutory prohibition, and the term “available”, with respect to eligible lands, means those lands that have been designated as open for leasing under a land use plan developed under section 1712 of title 43 and that have been nominated for leasing through the submission of an expression of interest, are subject to drainage in the absence of leasing, or are otherwise designated as available pursuant to regulations adopted by the Secretary. A lease shall be conditioned upon the payment of a royalty at a rate of not less than 12.5 percent in amount or value of the production removed or sold from the lease. The Secretary shall accept the highest bid from a responsible qualified bidder which is equal to or greater than the national minimum acceptable bid, without evaluation of the value of the lands proposed for lease. Leases shall be issued within 60 days following payment by the successful bidder of the remainder of the bonus bid, if any, and the annual rental for the first lease year. All bids for less than the national minimum acceptable bid shall be rejected. Lands for which no bids are received or for which the highest bid is less than the national minimum acceptable bid shall be offered promptly within 30 days for leasing under subsection (c) of this section and shall remain available for leasing for a period of 2 years after the competitive lease sale.
