The life-of-mine disturbance area from which topsoil was salvaged <br />(848.6 acres) and the topsoil stockpile sites as of December 31, 2008 are shown on the 2008 Topsoil <br />Replacement map. During 2008, there was no additional topsoil salvaged. The stockpile volumes are <br />listed in Table 08.1, Topsoil Stockpile Volumes. As of December 31, 2008, there were 70.5 acre-feet <br />of stockpiled topsoil remaining in the mining area. <br />Topsoil Replacement.
