As per the successful experience at NH2 Mine, it is believed that a high density <br />polyethylene (HDPE) pipeline is the best choice for the temporary and permanent <br />routes. Although expensive, WFC believes that this design will best suit the long term <br />needs of the CC Co. <br />WFC is evaluating two possible diversion routes for the proposed pipeline. One that <br />would begin at the easterly mine permit boundary and the route south along the county <br />road then around the mine area to the west and then north along 2600 Road to tie into <br />the existing ditch as it leaves the mine permit area. The second option would be to <br />begin the pipeline farther east to gain additional elevation drop as the pipeline swings <br />around the mine property. This additional elevation drop is desirous as it could provide <br />sufficient pressure to allow for side roll irrigation without the need for pumping. <br />Proposed pipeline construction would take place in the fall /winter of 2011/2012. <br />Installation would be undertaken well in advance of the irrigation season to ensure that <br />the system is fully functional when it is needed. <br />Once mining moves north of Meehan Draw and the area is restored to its approximate <br />original contour, the temporary line can be moved into the permanent location in the <br />winter of 2016 -2017. The permanent pipeline will be ready for use in the irrigation <br />season of 2016. <br />WFC is soliciting approval from the CC Company for the pipeline. <br />Design of the pipeline diversion was prepared by Del -Mont Consultants of Montrose <br />and their design details and all drawings are contained in Appendix 2.05.3(4) -4. Some <br />of the basic design characteristics are listed below. <br />6.2 Design Details <br />1) The pipeline will be a continuous fused polyethylene pipe of with no joints that <br />will roll with the terrain. This pipe is the best choice for tough applications and <br />long term durability. <br />2) The pipe wall thickness of is resistant to weather and wear and will remain <br />flexible. The polyethylene material is made to last indefinitely. <br />3) The pipe has excellent flow characteristics and will handle the full ditch flow <br />during the 6 years of temporary installation as well as for the permanent location. <br />4) Each takeoff will have a valve and a weir or flow meter for control and <br />measurement of the outflow. <br />5) The pipe is extremely durable and will avoid many pitfalls of other pipe types. <br />6) The temporary pipe will be laid on the surface while the permanent pipe will be <br />buried. The permanent line will not interfere with any post - reclamation land uses. <br />Section 2.05.3(4) Page 7 September 2014 (TR -06) <br />
