1. 1. All lessees, permittees or designated operators shall submit to the agency, and receive approval for, a plan of operations before any surface disturbance, drilling or other operations which disturb the surface of trust lands subject to a lease or permit. The operations plan shall include at a minimum proposed access and infrastructure locations and proposed site reclamation. Before approval, the agency may require the lessee, permittee or designated operator to adopt a special rehabilitation program for the particular property in question. Before the lessee, permittee or designated operator shall

   commence actual operations or before commencing any surface disturbance associated with the activity on lands subject to a lease or permit, the permittee, lessee or designated operator shall provide a plan of operations to the agency simultaneously with the filing of any required plan of operations or permit application with UDOGM. The agency will review any request for approval of operations and will grant approval providing that the proposed location and operations are not in violation of any rules or order of the agency. Before operations can commence, approval must be granted by the UDOGM, if required by statute, and by the agency. Notice of approval by the agency shall be given in an expeditious manner to UDOGM.

2. 2. Before approval of any surface disturbing operation, the agency may require the lessee, permittee or designated operator to:

   1. (a) provide when requested, a cultural, paleontological and biological survey on lands under lease or permit, including providing the agency a copy of any surveys required by other governmental agencies;
   2. (b) provide for reasonable mitigation of impacts to other trust resources occasioned by surface or sub-surface operations on the lease;
   3. (c) negotiate with the agency a surface use agreement, right-of-way agreement, or both for trust lands other than the leased or permitted lands, where the surface of said lands are necessary for the development of the lease or permit.
3. 3. Maintain a record of geologic data accumulated or acquired by the lessee, permittee or designated operator concerning the land described in the lease or permit. This record shall show the formations encountered and any other geologic or development information reasonably required by the agency and shall be available upon request by the agency. A copy of the record, as well as any other data related to geologic exploration or resource development on trust lands shall be deposited with the agency at the agency's request.

4. 4. Any operations which disturb the surface of lands contained within or on trust lands shall be required to be reclaimed by rehabilitation of the disturbed area as described in the plan of operations approved by the agency, and as required by the laws administered by the UDOGM or as required by any other state or federal agency.

   1. (a) In all cases, at a minimum, the lessee, permittee or designated operator shall agree to establish a slope on any excavations to a ratio not steeper than one foot vertically for each two feet of horizontal distance, unless otherwise approved by the agency and UDOGM before commencement of operations. The establishment of a stable slope shall be a concurrent part of the operation of the leased or permitted premises such that operations shall at no time constitute a hazard. Any pits, excavations, roads and pads shall be shaped to facilitate drainage and control erosion by following the best management practices.
   2. (b) In no case shall the pits or excavations be allowed to become a hazard to persons or livestock. Any material removed from trust lands shall be stockpiled and be used to fill the pits and for leveling and reclamation of roads and pads unless consent of the agency, and if applicable of UDOGM, to do otherwise is obtained, so at the termination of the lease, the land will as nearly as practicable approximate its original horizontal and vertical configuration. Any drill holes must be plugged in accordance with rules promulgated by UDOGM.
   3. (c) The agency shall require of the lessee, permittee or designated operator that all topsoil in the area of surface disturbance be removed, stockpiled, and stabilized on the trust lands until the completion of operations and satisfactory use in reclamation. During reclamation, the stockpiled topsoil shall be redistributed on the area of surface disturbance and the land revegetated as prescribed by the UDOGM and the agency. Any mud pits and temporary debris and settlement basins shall be filled and materials and debris removed from the site.
5. 5. Lessees, permittees or designated operators shall comply with any laws and notification requirements and operating rules promulgated by UDOGM or any other federal or state agency that may have regulatory jurisdiction over mineral development on trust lands or the leased or permitted substance.
