MCC and <br />the CDMG selected a vegetation community in the immediate vicinity of the mine which closely <br />approximated the biologic composition and character of a post-mine plant community as well as the <br />physical characteristics of the affected areas of the mine. This vegetation community was a former <br />agricultural and pasture area above the existing facilities area. The vegetation community and <br />physical characteristics (slope, aspect, drainage patterns) closely approximated the anticipated <br />• chazacter of the reclaimed landscape and vegetation community. <br />Revised Nw. 1996 PR07Rev.
