topography (See Pre-mining Topography Map (Map 18), Post-mining <br />Topography Map (Map 19) and Pre-mining and Post-mining Cross <br />Sections (Map 20)). Final grading for topsoil placement will be <br />done in a manner that reduces erosion and provides a surface for <br />topsoil that minimizes slippage. Prior to completion of topsoil <br />replacement on 3:1 (horizontal to vertical) slopes, a dozer will <br />construct a drainage control bench or furrow, where necessary, to <br />slow water flow on the longer slopes and minimize erosion. The <br />design Calculations for the benches and furrows are found in <br />Exhibit 7, Hydrology Information. At the completion of the final <br />grading, topsoil will be redistributed over the regraded spoil and <br />revegetated in accordance with Section 2.05.4. <br />Other surface treatments are also described in Section 2.05.4. A <br />list of the equipment used by Colowyo in order to perform the <br />day-to-day operation of coal mining is shown in Table 4, Equipment <br />List. <br /> <br /> <br />2.05-11 <br />
