LJ <br />' 2 <br />0 PIPELINE DESIGN AND SPECIFICATIONS <br /> . <br />' 2.1 Pipeline Design Criteria and Philosophy <br />The Yankee Gulch Project pipeline will be designed and constructed in <br />' accordance with applicable parts of the U.S. Department of Transportation (DOT) <br />Pipeline Safety Regulations contained in 49 CFR Part 195. Station piping will be <br />designed in accordance with ASME 31.4-1992 and 49 CFR Part 195. The State of <br />Colorado has not adopted any design codes applicable to the pipeline. Because <br />these DOT pipeline standards apply specifically to transportation of hazardous <br />liquids by pipeline, some of the standards may not be appropriate or necessary for <br />the Yankee Gulch Project pipelines. In addition, because of the insulation and <br />coating on the pipes and because of other specific features, the pipes may need to <br />' be handled differently than regular steel pipe. <br />The pipeline will be designed by The Williams Companies, which is a partner in <br />' American Soda. Pipeline standards contained in "The Williams Companies <br />Onshore Pipeline Construction Specifications" (dated 9 June 1997) will apply to <br />pipeline construction. The Williams Companies specifications meet or exceed <br />DOT standards and also provide more detailed construction specifications that <br />are consistent with the requirements of the DOT standards. <br />' Although the pipeline will be designed and constructed in accordance with <br />applicable parts of the DOT standards, the pipeline will not be regulated by DOT <br />and consequently will not be operated under DOT operating standards. <br />' 2.2 Pipe Specifications <br />' As described above, the pipelines will be designed according to the Williams <br />Companies standards and detailed construction specifications, which meet or <br />exceed DOT standards. <br />' • Design Pressures: The maximum allowable operating pressure for the <br />project pipes is 2,160 pounds per square inch gage (psig). A 72 percent design <br />factor of the yield strength of steel is the determining factor in the wall thickness <br />of the pipe. <br />• Pipe: The mainline pipe diameter, wall thickness requirements, and steel <br />pipe characteristics for the Yankee Gulch Project pipeline system are based on <br />' meeting maximum allowable operating pressures. The pipes will be of the <br />following inside diameters: 10.75-inch, 12.75-inch, or 14.00-inch. All pipe will be <br />covered by 3.25 to 3.50 inches of insulative and protective coatings. Pipes will be <br />' in nominal 40-foot or 80-foot lengths <br />PipeLne Wormaoon Summary A <br />Ya~ee GWCh Sodnm Minerals Pro~ecr <br />' Ammcan Sofa, L.L.P. <br />
