# §3210.10. When does lease segregation occur?

- (a) **Lease segregation occurs when—**
  - (1) A portion of a lease is committed to a unit agreement while other portions are not committed; or
  - (2) **Only a portion of a lease remains in a participating area when the unit contracts.** The portions of the lease outside the participating area are eliminated from the unit agreement and segregated as of the effective date of the unit contraction.
- (b) BLM will assign the original lease serial number to the portion within the agreement. BLM will give the lease portion outside the agreement a new serial number, and the same lease terms as the original lease.
