CNAPTERTWO Proposed Action and Alternatives <br />practices. Lights in the well field would be switch operated and would only be used when active <br />work is being conducted at a particulaz location. <br />Hazardous Materials <br />Table 2-5 lists the hazardous materials that aze expected to be used for construction and operation <br />of the Yankee Gulch Project, and it includes the storage location and quantity of materials stored. <br />Hazazdous materials would be properly stored and identified within the storage buildings at the <br />respective sites. Gasoline and diesel fuel would be stored inabove-ground tanks within a bermed <br />azea. <br />2.2.2 Pipeline <br />2.2.2.1 Pipeline Corridor <br />The project would require the installation and use of two, 43.4-mile-long, like-constructed <br />pipelines - a product pipeline and a return water pipeline. The project pipelines would be buried <br />and would be routed pazallel to existing pipeline corridors for approximately 33 miles. There is <br />no existing corridor neazby for miles 0 through 7 across the Piceance Site or for cniles 32 through <br />35 where the pipeline descends Davis Point (Figure 2-If). <br />Installation of the pipeline would require a maximum 125-foot-wide construction. right-of--way <br />and would disturb approximately 667 acres over the 43.4-mile-long pipeline corridor. In the long <br />term, however, a maximum 50-foot-wide permanent easement would occupy approximately 267 <br />acres. For purposes of analysis in the EIS, it is assumed that the right-of--way (ROW) would be <br />all ne~v disturbance. In actuality, it is estimated that up to 25 feet of the construction ROW may <br />overlap existing pipeline corridors in certain locations. <br />2.2.2.2 Pipeline Description <br />The pipeline, though not regulated by the US Department of Transportation (USI)OT), would be <br />designed, constructed, and installed in accordance with construction specifications that meet or <br />exceed applicable USDOT standazds. <br />The pipelines would be constructed of 10.75-, 12.75-, or 14.00-inch-diameter pipes covered by <br />insulative and protective coatings; pipes would be in nominal 40-foot or 80-foot lengths. Both <br />pipelines would be constructed with American Petroleum Institute SL grade steel. Pipe <br />diameters, wall thickness requirements, and steel pipe chazacteristics would be based on meeting <br />Maximum Allowable Operating Pressure. The wall thickness of the pipe may be increased in <br />areas of road crossings to meet jurisdictional restraints and design philosophy. All pipes would <br />have 12 to 14 mils of fusion-bonded epoxy (FBE) external corrosion coating. <br />Due to required operating conditions, the pipelines would have an insulated jacket to minimize <br />heat loss during transport of fluids between the Piceance Site and the Pazachute Site. The <br />insulated jacket would consist of three components: 1) the heat-resistant FBE de:>cribed above <br />would be applied to the pipe, 2) a closed-cell polyurethane foam with nominal thickness of three <br />2-12 <br />
