TAB 9 <br />• ATTACIII~TIP 9-2A <br />I V SOIL SURVEY ADDITION - EAST` PIT <br />INTRODUCTION <br />III III III IIIIIIIIII <br />sss <br />Doc Date:12/11/2001 <br />Peabody Coal Canpany will disturb approximately 5.1 acres of <br />native soils in Section 31 during 1980 and 1981. Previous dis- <br />turbance southeast of the present pit from July 1978 through <br />1979 totalled 4.4 acres. The disturbance schedule for the east <br />pit is inclu3e3 as part of the Topsoil t•]anagement Plan and <br />Sci~edule (Tab 9, Attachment 9-1). <br />Active mining will terminate in Section 31 following the 1980 <br />pit disturbance of 0.4 acres (see Exhibit 12-1). There will be <br />additional disturbance to the northwest in 1981. This distur- <br />• bance comprises 4.7 acres and is associated with highwall reduc- <br />tion. To predict the quality and quantity of topsoil to be <br />removed from this area (5.1 acres), the following soil assess- <br />ment was completed. <br />DES~RIPTICN OF TIO; AREA <br />The East Pit Soil Survey Addition is located 0.5 miles southwest <br />of the Nucla Mine office in the SW 1/4 NW 1/4 aryl the NW 1/4 <br />SP7 1/4 of Section 31, Township 47N, Range 15W in Montrose County, <br />Colorado. The field soil survey map boundary extends well beyond <br />the expected disturtxznce area. This survey area is delineated <br />on the Soil Type and Stripping Isopach Maps containe3 in Exhibit <br />9. Stockpile locations 1 through 4, 13, and 14 are located near <br />the east pit. Topsoil is currently salvaged ahead of the pit <br />disturbance using dozers and scrapers. Topsoil fran this area <br />has most recently been stored in Stockpile 14 (see Exhibit 9-2). <br />81 <br />• <br />
