Additional Surface Permitting

Although the State Uranium Lease grants the right of ingress and egress related to the leased property; and, allow use of the surface as needed for operations, all mineral lessees are required to contact the surface lessee and negotiate Surface Impact Payments (SIP) as necessary. SIPs are intended to mitigate surface disturbance caused by mineral development.

Use of State Land outside the bounds of the mineral lease require additional permitting. Long term additional permitting, such as disposal wells, on-lease facilities handling off-lease minerals, or communication towers require a Special Use Lease (SUL). Short term permits such as roads or reserve pits, access roads, or construction activities, a Temporary Use Permit (TUP) is issued. Although the mineral lease allows for ingress and egress related to the leased parcel, access routes across parcels that are not within the lease area are subject to TUP permitting.

Lease expiration occurs at the end of the primary term, extension of primary term, or renewed lease term on leases which have not been developed or are diligently pursuing production. Lease expiration is an automitic function of lease terms and no notice is provided to lessees of expiring leases.

Surface Integrity and Minimum Reclamation

Uranium leases are required to maintained to be maintained in an ecologically prudent manner. When a lease is finally disposed of, reclamation of the disturbed areas must take place. Reclamation of the site is required to have vegetative composition and production similar to the surrounding rangeland and for the site to be physically stable. Surface compliance and reclamation inspections are performed by the Field Services Division (FSD) of OSLI.

Uranium lessees are encouraged to contact OSLI when surface compliance issues may arise so that the situation can be handled in a timely manner. Reclamation planning with OSLI staff is suggested so that reclamation plans can be tailored to meet the expectations of OSLI, expediting the reclamation process. FSD contact information can be found on the Contact page.
