(a) All lands in an oil shale lease must be described by the legal subdivisions of the public land survey system or if the lands are unsurveyed, the legal description by metes and bounds.

(b) Unsurveyed lands will be surveyed, at the cost of the lease applicant, by a surveyor approved or employed by the BLM.

No entity may hold more than 50,000 acres of Federal oil shale leases on public lands and 50,000 acres on acquired lands in any one state. Oil shale lease acreage does not count toward acreage limitations associated with leases for other minerals.

In computing the maximum acreage an entity may hold under a Federal lease, on either public lands or acquired lands, in any one state, acquired lands and public lands are counted separately. An entity may hold up to the maximum acreage of each at the same time.
