CHAPTERFIVE Draft EIS Recisions <br />include Castner, Glendive, Irigul-Pazachute, Red Creek, Redcreek-Rentsac, and Nihill soils, <br />which are distributed along the entire pipeline corridor. <br />Where topsoil is 6 inches or greater in depth, it would be segregated and stored along the ROW. <br />Immediately following pipeline installation, subsoil material would be replaced in the trench, and <br />any salvaged topsoil would be placed on top. Revegetation of the pipeline corridor would be <br />initiated during the first fall following pipeline installation. Upon successful revegetation of the <br />pipeline corridor with grasses and forbs, soils would be stabilized and the site returned to <br />productive use. Some areas may not be reclaimed effectively where broken bedrock is left <br />exposed or other adverse surface conditions exist. <br />This alternative is similar to the Proposed Action, and, for the soils resource, there would not be <br />a notable difference in impacts. A few project facilities would be enlazged, and Table 4.2-2 <br />shows the acres of disturbance for this alternative. Table B-6 in Appendix B shows acres of <br />disturbance by soil type. About ~SG.S 1,621.5 acres would be disturbed under this alternative; <br />however, only an additional 4 acres of fragile soils would be affected compazed with the <br />Proposed Action. Two pump stations neaz Davis Point, although not formally designed and <br />sited, would likely occupy fragile soils for the 10-yeaz life of the project. <br />Page 4-13; Groundwater <br />The Yankee Gulch Project, as proposed in the Mine Plan, would not utilize . at the Piceance Site. <br />Water for processing at this site would be transported via pipeline from the Parachute Site. This <br />water would consist of return and recycled water, along with some make-up water. Make-up <br />water would be acquired from the Colorado River through an existing water right and from <br />alluvial groundwater wells in the Parachute Creek valley through an existing water right. Since <br />these are existing water rights, impacts of the water withdrawal have been accounted for and will <br />not be evaluated further in this section. Potential effects on endangered fish species in the <br />Colorado River from water depletion are discussed in Section 4.10.2.1. Drinking water for the <br />Piceance Site would be transported to the site by truck. <br />Page 4-18 <br />4.5 METEOROLOGY AND AIR QUALITY <br />4.5.1 Introduction <br />Air quality in the study area would be affected during the construction and operation of the <br />proposed project. However, no significant impact udll would occur under the Proposed Action. <br />The proposed Yankee Gulch Project would involve air emissions resulting from the installation <br />of various stationary sources associated with the process facilities at both the Piceance Site and <br />the Parachute Site, and fugitive dust sources including roads and construction activity. The <br />primary effect to air quality would be a result of particulate emissions from product <br />processingzwd, oxides of nitrogen (NO,J emissions resulting from the burning of fossil fuels. <br />~ere~szlse-a, and potential ~ cazbon monoxide (CO) emissions resulting from the <br />product dryer. eke Although the solution mining and drilling/construction processes are Aei <br />expected designed not to break down the organic (oil shale) deposits, <br />5-19 <br />
