<br />revegetation. However, as much as possible, topsoil /overburden
<br />will be immediately used in previously mined areas to build
<br />the required slopes of the reservoir and for revegetation of
<br />1
<br />the banks /periphery areas. Topsoil /overburden may also be
<br />temporarily stored on the future berm along the South Platte
