General gradation and characteristics of material Reclamation <br />side of pit has been regraded. Hichwall (west side) was recraded complete for <br />in August and now. East <br />September <br /> 1995 and looks good Two areas on hiahwall side will require so me maintenance repairs <br /> Some topsoil has been replaced at the very northern end of the fill area. <br />3.
