Section 20.03.16.090 - UNIT OR COOPERATIVE PLANS OF DEVELOPMENT OR OPERATION01.Unit Plan. For the purpose of properly conserving the natural resources of any oil and gas pool, field or like area, the lessee may, with the written consent of the Director, commit the leased lands to a unit, cooperative or other plan of development or operation with other state, federal, Indian, or privately-owned lands.02.Contents. An agreement to unitize must: describe the separate tracts comprising the unit; disclose the apportionment of the production of royalties and costs to the several parties; the name of the operation; and contain adequate provisions for the protection of the interests of all parties, including the state. The agreement must: be signed by or in behalf of those persons or entities having effective control of the geologic structure; submitted to the Director with the application to unitize; and effective only after approval by the Director.03.Interested Parties. The owners of any right, title or interest in the oil and gas resources to be developed or operated under an agreement may be regarded as interested parties to a proposed unitization agreement. Signature of a party with only an overriding royalty interest in unnecessary.04.Collective Bond. In lieu of separate bonds for each lease committed to a unit agreement, the unit operator may furnish and maintain a collective corporate surety bond or a collateral bond conditioned upon faithful performance of the duties and obligations of the agreement, the lease subject to the agreement and these rules. The liability under the bond will be for such amount the Director determines to be adequate to protect the interests of the state. If the unit operator is changed, a new bond or consent of surety to the change in principal under the existing bond must be filed within thirty (30) days of assignment.05.Lease Modification. The terms of any lease included in any cooperative or unit plan of development or operation may be modified by the Director with approval of the lessee, except that a unit agreement must have final approval by the Director for a state cooperative plan or the final approval by the secretary of interior for a federal cooperative plan prior to extending any lease into its eleventh year and each year thereafter. A lease so extended expires two (2) years after the unit plan expires provided the lessee continues to pay the annual rental as outlined in Subsection 041.03.06.Rentals. Rentals and royalties on leases so extended are at the rates specified in these rules. Advanced rental must be paid on or before the extended lease's anniversary date. Any unused portion of annual rental will not be refunded.07.Evidence of Agreement. Before issuance of a lease for lands within an approved unit agreement, the lease applicant must file with the Department evidence that he has entered into an agreement with the unit operator for the development and operation of the lands in a lease, or a statement giving satisfactory reasons for the failure to enter into such agreement. If such statement is acceptable, the applicant will be permitted to operate independently but be required to perform its operations in a manner that the Director deems to be consistent with the unit operations.08.Segregation Prohibited. A lease may not be segregated if any part thereof is included in a cooperative plan until the pool or field has been defined. Once defined, those areas outside the unit area or pool boundary can be surrendered as provided in Section 070.Idaho Admin. Code r. 20.03.16.090
