as described in the footnotes is vague ("up to potentially 3-4 feet"). Additional <br />clarification is warranted. <br />a. Please provide separate cross-sections for West Pit and South <br />Taylor soil replacement depths. South Taylor cross-section <br />should depict two separate replacement zones (upper and lower) <br />for slopes greater than 10%. <br />Colowvo's Response: <br />As agreed, Colotiiyo has further amended the genetic cross section to <br />provide additional clctrifrcation, precluding the need to provide separate cross- <br />sections. <br />b. Please specify both a range and average thickness for the thick <br />soil (lower V2 slope) replacement zone in the South Taylor Area. <br />Average thickness for these thick soil zones should be at least <br />30". Text and/or diagram footnotes for South Taylor will need <br />to specify that, within designated aspen and thick soil tall shrub <br />establishment areas, average replacement thickness will be at <br />least 48", regardless of slope grade (refer to excerpt from <br />CDOW letter on page 2.05-49, which recommends creation of <br />sites with extremely deep topsoil depths for the benefit of woody <br />species like aspen and chokecherry). <br />Colotivyo's Response: <br />As agreed, Coloit?yo has provided thickness ranges for the pertinent <br />locations, along the slopes in reclamation areas in the Sotith Taylor mining area. <br />As agreed, an additional footnote hvs been added to the cross section that states <br />"Specific details regarding Topsoil replacement depths on special planting areas <br />ii,ill he inchided in the description pi-w4ded for approval prior to the creation of <br />those areas , <br />2. This question is based on the cross-sections as discussed in question 1 above. <br />Please include a generic cross-section for both the West Pit and the South <br />Taylor Pit, using the pit specific replacement zones in the appropriate cross- <br />section. <br />Colowti'o's Response: <br />Please see responses to Item I. <br />3. Response Accepted. Colowyo has provided the requested clarification regarding <br />the variable topsoil replacement plan. The text on pages 2.05-46 and 2.05-47 <br />adequately addressed the Division's concern. <br />4. The Division requested that Colowyo include a current topsoil balance chart <br />addressing the current topsoil balance for various areas within the original permit
