Title 30 › Chapter 3A— LEASES AND PROSPECTING PERMITS › Subchapter II— COAL › § 202a
The Secretary can approve joining coal leases into one "logical mining unit" when doing so will help get the most coal out. A logical mining unit is an area where the coal can be mined as one efficient operation; it can include federal and nearby non-federal lands, but the whole area must be under one operator’s control, be contiguous, and be able to be developed as a single operation. If anyone whose interests might be hurt asks, a public hearing must be held before approval. Once a unit is approved, mine plans must show the unit’s coal will be mined within a time set by the Secretary, normally no more than 40 years unless the Secretary allows a longer period to ensure maximum recovery or orderly, efficient, or economical development. The Secretary can treat work on one lease as meeting requirements for all leases in the unit, combine rentals and royalties and apply advanced royalty credits across the unit, and change lease terms to match unit rules. Existing leases can join only with all lessees’ consent. The Secretary can require unit formation by rule and decide participating acreage. A unit cannot be larger than 25,000 acres, and these rules do not waive the acreage limits in section 184(a).
