Title 30 › CHAPTER 3A — LEASES AND PROSPECTING PERMITS › SUBCHAPTER II — COAL › § 202a
The Secretary can allow coal leases to be joined into one "logical mining unit" when that will help recover the most coal. Anyone who might be harmed can ask for a public hearing before the joining happens. A logical mining unit is land that can be mined efficiently as one operation. It must be next to each other, run by one operator, and can include nearby non‑federal lands between or beside federal leases. After approval, the unit’s mining plan must mine the unit’s coal within a time set by the Secretary, normally no more than 40 years. The Secretary may allow a longer time if it will lead to greater recovery or more orderly, efficient, or economical development. The Secretary may count work on one lease as meeting requirements for all leases in the unit, combine rent and royalty payments, and apply advance royalties across the unit. Leases can be changed to follow unit rules. Older leases can join only if all leaseholders agree. The Secretary may require units by rule and decide participating acreage. No unit may be larger than 25,000 acres. This does not remove the acreage limits in section 184(a).
