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 rupture, in the unlikely event that a pipeline failure should occur. It is anticipated that in the event insulation around [he 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 [he 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 EC 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, EC is not obligated to any long-term reclamation liability associated with the pipeline corridor. County Road 107 County Road 107, which covers the property from the southwest to the northeast, is an unimproved gravel road maintained by EC. This road has been abandoned by the County to the northeast of [he mine complex and has been vacated to EC. Subsidence is planned under portions of the existing road right-of-way. EC proposes to maintain the road as necessary for its own use. State Highway 13 The planned five-(5) year mining sequence places State Highway 13 outside the area of possible surface subsidence effects. However, EC plans to monitor State Highway 13 in areas where mining is planned adjacent [o the road. In [he unlikely and highly improbable even[ [hat 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 Pacific (formerly Denver and Rio Grande Railroad Spur) The planned five-(5) year mining sequence places the railroad spur {UP) outside the area of possible subsidence effects. However, life-of-mine mining will undermine the railroad spur. In this area, EC will develop a monitoring program and submit it to the CMLRD for their review and approval. If the monitoring program indicates that subsidence is impacting the railroad spur, EC will immediately notify the UP Railroad and the appropriate agencies. EC will begin repair of the railroad. All work will be carried out under the direction of the UP Railroad. Irrieation 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, EC will develop a monitoring program and submit it to the CMLRD for their review and approval, in writing. If the monitoring program indicates that subsidence is impacting the irrigation ditches, EC will repair or replace the damaged ditches at their option. Permit Revision 04-34 2.05-65 Revised 7/2/04
