the pipeline has been completed. This will allow for visual assessment of the pipeline, and access to the pipeline to provide temporary support or leveling in the event some action is required during undermining. In addition, this will allow rapid access for control and repair of a pipeline rapture, in the unlikely event that a pipeline failure should occur. It is anticipated that in the event insulation around the pipe is needed to maintain pumping due to weather conditions while the trench is open, either straw or sawdust may be packed around the pipe. Upon completion of undermining, this material would then be incorporated into the solid during burial of the pipeline and would act as a fertilizer. A side benefit of using these materials for insulation would be their absorbent capacities in the unlikely event of a pipeline failure during the undermining process. In the event of a pipeline failure, any oil that is collected on the surface will be cleaned up and disposed of in a workmanlike manner and in accordance with all applicable regulations. Likewise, any soil that becomes contaminated will be disposed of in the proper fashion. Following completion of undermining, and prior to final burial of the pipeline, an inspection and any necessary repairs to the pipeline segment will be conducted. In the event repairs are required, an Amoco contractor will perform the work under Amoco guidance, and CEC will reimburse Amoco for the cost of the repairs. Amoco's reclamation of the site will involve regrading, topsoiling, and revegetation. Given that Amoco is creating the disturbance associated with the pipeline work, and is also doing the reclamation work, CEC is not obligated to any long-term reclamation liability associated with the pipeline corridor. County Road 107, which covers the property from the southwest to the northeast, is an unimproved gravel road • maintained by CEC. This road has been abandoned by the County to the northeast of the mine complex and has been vacated to CEC. Subsidence is planned under portions of the existing road right-of--way. CEC proposes to maintain the road as necessary for its own use. State Hiehwav 13 The planned five-(5) year mining sequence places State Highway 13 outside the area of possible surface subsidence effects. However, CEC plans to monitor State Highway 13 in areas where mining is planned adjacent to the road. In the unlikely and highly improbable event that subsidence impacts State Highway 13, the road will be barricaded, if necessary, after notifying the appropriate agencies. Once the safety of the public has been assured by the notification of the agencies of the potential hazardous condition, then repair of the road will begin. All repair work will be carried out under the direction of the State Highway Department. Union Pacifj~formerly~enver and Rio Grande Railroad Sourl The planned five-(5) year mining sequence places the railroad spur (LIP) outside the area of possible subsidence effects. However, life-of-mine mining will undermine the raiUoad spur. in this area, CEC will develop a monitoring program and submit it to the MLRD for their review and approval. If the monitoring program indicates that subsidence is impacting the railroad spur, CEC will immediately notify the UP Railroad and the appropriate agencies. CEC will begin repair of the railroad. All work will be carved out under the direction of the UP Railroad. Irrigation Ditches The planned five-(5) year mining sequence places the irrigation ditches outside of the area of possible subsidence • effects. However, life-of- mine mining will locally undermine the imgation ditches. In these areas, CEC will develop a monitoring program and submit it to the MLRD for their review and approval, in writing. If the monitoring program indicates that subsidence is impacting the irrigation ditches, CEC will repair or replace the damaged ditches at their option. Permit Renewal No 3 2.05-65 7/15/98
