The final urea of disturbance will be minimized, but the area of permanent <br />disturbance will be determined when the structure surueys are completed. The total <br />length of the line is estimated to be 11.25 miles. , <br />2l. Section 2.1.2.4, page 2-8 -Water. Elsewhere there is a mention of the possibility of water <br />veatment. Please describe. Where will this be done? <br />Due to the hardness of the water and its adverse affects on the processes involved, <br />the water must be processed to remove the majority of the Calcium and Magnesium <br />hardness. The water for the entire project will be provided from the water rights <br />associated with the UNOCAL facility. The water will be treated at the Parachute Site <br />and the treated water required at the upper facility at Piceance Creek will be pumped <br />to the upper plant site. The effluents from the water treatment process will be <br />pumped into the Parachute Site evaporation pond. <br />22. Section 2.1.4.1, page 2-9 -Solution piping. We need a complete description of the pipe <br />racks -how many pipes on a rack, how big a diameter, total height and width. Is there any <br />reason the pipes can't be placed on the ground? How bulletproof aze they? (there will probably <br />be hunters nearby). How many miles of pipe? <br />The well field piping will consist of the main header system that transits the well <br />field area and feeds into the process plant. Off of the main header system, a series of <br />lateral pipe systems will 6e routed into areas of the well field to connect to the <br />individual wells in the field areas. All of the Header and lateral pipe racks will have <br />three process'solution pipelines, a nitrogen gas line and an electrical conduit. The <br />main header process pipeline sizes will be 12 inches diameter, the lateral piping will <br />be 8 inch and the individual well connectittg pipes will be 4 inch. The Nitrogen <br />header will be 6 inch, the laterals will be 2 inch and the individual well piping will <br />be 2inch pipes. <br />Because the pipes will be insulated and there will be thermal expansion and <br />contraction on the lines it will be necessary to place the pipes on low pipe racks so <br />that the insulation will not be dnmaged. The pipes will be schedule 40 pipes and <br />depending on the caliber of the weapon used it could be possible to damage the pipes <br />with a bullet. Drawings for the main header, lateral, and individual well piperacks <br />are attached. <br />In the 0-5 year panel, the total length of the main header pipe system is estimated to <br />be 8,500 feet. The length of the lateral piping systems is estimated at 6,400 feet, and <br />the individual well piping system is estimated to be 3,900 feet. A cleared corridor of <br />10 feet is estimated for constriction of the main header and lateral systems. A n <br />additional corridor of 10 feet zui[I be used for construction of the main header and <br />Interal systems. The individual well piping will require a cleared corridor of 8 feet <br />and an additional 8 feet for construction. <br />12 <br />
