Title 30 › CHAPTER 23 — GEOTHERMAL RESOURCES › § 1017
Unit agreement — a plan where leaseholders run a whole geothermal reservoir or part of it together. Communitization agreement — a plan that pools separate tracts and splits production or royalties among them. Lease owners may join together and operate their geothermal area under a unit agreement when it helps protect the resource. A majority of owners of one lease can make that lease join a unit. The Secretary of the Interior can start or require unit agreements, can set or change operating conditions with lessees’ consent, and can require new federal leases to say they must follow a unit plan. Leases with different terms or royalty rates do not have to be changed to match each other. If separate tracts cannot be developed alone, the Secretary may allow pooling under a communitization agreement so production or royalties are shared and treated as production for each tract. The Secretary must review each approved unit agreement within 5 years and at least every 5 years after that. After notice and comment, the Secretary can remove land from a unit if science shows it is not needed to manage the resource and removal helps conserve it. Removed land may be eligible for extension under section 1005(g) if it meets those rules. The Secretary may approve drilling or development contracts and leases run under those contracts are treated differently for holdings or control rules. The Secretary must coordinate unitization and pooling with state agencies.
