INTRODUCTION <br />Proiect Team <br />The project team involved with the Climax Storke Pipeline project were as <br />follows: <br />Owner: Climax Molybdenum Co., a division of Phelps Dodge Corp. <br />Engineer: W. W. Wheeler and Associates, Inc., Englewood, CO <br />Contractor: R. L. Beck Excavating, LLC, Leadville, CO <br />Kumar and Associates of Denver, CO was used to analyze concrete samples .,. <br />and provided geo-technical consultations as required. Mountain States Pipe and Supply <br />of Colorado Springs,,CO was used fo fuse the HDPE pipe sections and fittings. <br />Proiect Description . <br />The Climax Storke Pipeline is a process water transfer pipeline, used to transfer <br />untreated mine waterfrom the Climax-#5wShaft pump station to an existing discharge <br />pipeline near the top of Freemont Pass. The water is then delivered to.the..Tailing...,,,. __ _. <br />Distribution House and-on ~o the Climax-tailing ponds, where it is chemically-rtreated~ <br />before being released. The treatment process for this water is not a part of this project, <br />and is not described further. <br />The overall length of the pipeline is approximately 4250 feet. The majority of the <br />Storke pipeline consists of 24-inch O.D. HDPE pipe of various pressure ratings. The <br />pipe was manufactured in 50 feet long sections and the sections were joined using a <br />heat-fusion process. A short section (about 50 feet) of the pipeline in the #5 Shaft <br />Personnel Tunnel (PT) is fabricated from 316 stainless steel, and connects to the <br />existing 16-inch HDPE pipe in the PT. <br />The 24-inch HDPE pipeline is installed along an existing bench paralleling State <br />Highway 91. There are four cleanout ports located along the pipeline at approximately <br />900 feet intervals. These cleanouts consist of "tees" installed in concrete manholes, with <br />1 <br />
