Post - mining contour map 2.05.4 -1 shows the proposed final contours. This map shows the
overburden box -cut stockpile, the topsoil stockpile, and sediment ponds NHN -001, NHN-
002, and NHN -003 remaining as permanent features. This final configuration is not in
agreement with Section 34- 33- 120(2)(c) and Rule 4.14(2)(a) and (d), and 4.14;2(1). Please
provide a map that shows the final post- mining contours of the facilities area including the
temporary box-cut spoil stockpile and the topsoil stockpile. Haul roads, mine facilities, and
years of mining should also be deleted from this map. If the ponds are to remain as
permanent features, please provide the appropriate demonstrations required by Rule
4.05.9(13). Item reso&ed in Aft = -2011 r °esl onse.

3. The post - Whiling contours on map 2.05.4 -1 show smooth straight slopes in the Gainey,
Meehan and Glasier properties. This map does not show where drainage ways will be
reestablished. The Division has 30 +years of experience with observing reclaimed slopes
and has noted that smooth straight slopes exhibit more erosion and gullying that reclaimed
slopes with undulations and slope variations. Please discuss why there are no erosion
control ditches or terracing proposed for the reclaimed slopes. Please submit post - mining
contours that have contours that more closely resemble the approximate original contours,
4.14.2(1). Item resolted in 1 ltty -2011 resImnse.
