The location of the pipeline structure on Map 2.05.4-5 is the permanent location. The design <br />details and historical information regarding the ditch relocation can be seen below. <br />T. Historical Information Regarding CCC Ditch Relocation <br />The following information is from the original CCC ditch relocation sub -section of the New <br />Horizon Mine Permit. As of the Mid Term Review of 2006, the HDPE pipeline was installed as <br />described below and has operated with no significant problems. All ditch users are satisfied with <br />the performance of the pipeline. It is important to note that the CC Company has accepted the <br />pipeline as a permanent structure, and the surface landowners have provided access to the CCC <br />ditch head gate. The location of the pipeline structure on Map 2.05.4-5 is the permanent location. <br />The Colorado Cooperative Company as operated an irrigation ditch known as the West Lateral <br />Ditch to irrigate lands in the area for many decades. With the mines advance to the north though <br />BB Road; this ditch needs to be diverted. Since the temporary detour route involves rises and <br />dips, a pipeline must be used. The plans enclosed in this document show the detailed design of <br />the pipeline temporary route and the permanent relocation. <br />After evaluation of all alternatives, it is believed that a high density polyethylene (HDPE) <br />pipeline is the best choice for the temporary and permanent routes. Although expensive, we feel <br />that this design will best suit the long term needs of the Colorado Cooperative Company. <br />The portion of ditch to be replaced begins near the eastern portion of the Martin property and <br />ends at the ditch crossing of 2700 Road. This distance is approximately 4616 feet with an <br />elevation drop of 77 feet. This is an average grade of 1.67%. The ditch will be disrupted in early <br />2002; therefore the temporary route will need to be installed prior to this time. Installation would <br />be undertaken well in advance of the irrigation season to ensure that the system is fully <br />functional when it is needed. <br />The logical location for the temporary route is south along the east side of the Martin property, <br />then in a curve on the reclaimed area below BB Road and then west to meet the existing ditch <br />immediately before it enters the existing culvert under 2700 Road. This is a distance of <br />approximately 3800 feet. Review of the final contours in the existing reclaimed area shows that <br />there is a rise in the reclaimed land along the temporary route, thus it is not possible to put the <br />temporary route in as an open ditch. For this reason, some type of pipeline is needed. The <br />Reeder/Garret/Johnson takeoff will be supplied by smaller pipe that will leave the main pipe <br />near the exit and continue north along 2700 Road to the existing distribution box. <br />Section 2.05.3(3) Page 40 September 2017 (TR -81) <br />
