Additional Required Permitting

Surface Impact Payment

Although State Bentonite leases give 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 pay a Surface Impact Payments (SIP). SIPs are intended ot re-compensate the grazing lessee of the stat surface as well as OSLI for the loss of forage associated with Bentonite development disturbance. Surface impact payments are required to be negotiated prior to exploration and development on any State mineral lease.

Board of Land Commissioners' Rules and Regulations, Chapter 4, Section 14.

Special Use Leasing and Temporary Use Permit

Use of State Land outside the bounds of the mineral lease require additional permitting. This is handled in two manners. For long term additional permitting, a Special Use Lease may be required. Situations requiring a Special Use Lease (SUL) could include disposal wells, on-lease facilities handling off-lease minerals, or communication towers. For short term permits such as roads or CBM reservoirs, Temporary Use Permits (TUP) are 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. For more information on SUL's and TUP's please refer to the links below.

Lease Relinquishment, Termination, and Expiration


A lessee may relinquish a lease for various reasons, using the form below. If the lease being relinquished is not developed in anyway, the lease is relinquished effective the day it is received by OSLI. If the lease being relinquished has been developed, the relinquishment will not be effective until the lands leased are reclaimed to an acceptable condition. Relinquishment of a lease does not relieve a lessee of obligations due to that lease. Parcels may be offered for lease after a lease has been relinquished on that parcel.

Surrender and Relinquishment Form


Termination of lease can be due to a variety of reasons including; no production without suspension of operations, failure to pay annual rental, or default of lease or SBLC Rules and Regulations, etc. The lessee of a terminating lease will receive thirty (30) notice of the lease termination. If no response or remedy is received within that thirty days, the lease will terminate on the appropriate effective date. Parcels may be offered to lease after a lease on that parcel has been terminated.


Expiration of leases occurs when a lease has reached the end of it’s primary term without production or diligent pursuit of production, or without extension or renewal of the primary term. Leases that have reached the end of their primary term without production or extension expire automatically as a function of the lease. Parcels that may be offered for lease after a lease on that parcel has expired.

Surface Integrity and Minimum Reclamation

Bentonite leases are required to be maintained in an ecologically prudent manner. Furthermore, when a lease is finally disposed of, reclamation of the disturbed areas must take place. Reclamation of the site is required to have vegetative production as good or better than 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.

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