Once mining moves west of 2700 Road and the area is restored to its approximate original <br />contour, the temporary line can be moved into the permanent location in the winter of 2004- <br />2005. The permanent pipeline will be ready for use in the irrigation season of 2005. <br />1. Design Details <br />a. The pipeline will be a continuous fused polyethylene pipe of 28 inch outside diameter <br />with no joints that will roll with the terrain. This pipe is the best choice for tough <br />applications and long term durability. <br />b. The pipe wall thickness of 1.33 inches is resistant to weather and wear and will remain <br />flexible. The polyethylene material is made to last indefinitely. <br />c. Other specifications: 80 psi rating (more than adequate), inside diameter 26.33 inches, <br />length of approximately 4000 feet. <br />d. The pipe has excellent flow characteristics and will handle 25 cfs during the 6 years of <br />temporary installation and will pass 38 cfs for the permanent location. All takeoffs for <br />irrigation in the permanent line will be based on a main pipe flow of 38 cfs. <br />e. Each takeoff will have a valve and weir for control and measurement of the outflow. <br />f. The pipe is extremely durable and will avoid many pitfalls of other pipe types. <br />g. The temporary pipe will be laid on the surface while the permanent pipe will be buried. <br />The permanent line will not interfere with any post -reclamation land uses. <br />h. A pressure regulator will be placed in the line near the exit to control flow in the pipe. <br />i. During the temporary pipe time frame, the Reeder/Garret/Johnson distribution box will <br />be supplied from an 8" diameter SDR 26 pipe leading from the main pipe. <br />2. Timing <br />Temporary pipe will be laid during sometime in 2001 and will be put into operation either during <br />for the latter part of the irrigation season of 2001 or will be ready for the 2002 season. This will <br />depend on mining advance. <br />After mining continues west of 2700 Road and the area for the permanent line has been <br />backfilled and graded, the permanent line can be installed and should be ready for the 2005 <br />irrigation season. <br />U. Relocation of Utilities <br />1. Electric <br />When the mining operation crosses BB Road, the buried phone line and overhead power line <br />along it will be relocated to the BB Detour Road.
