Notes:
(A) Total material mined
(B) Water retained In product calculated as 4% of aggregate production
(C) Water used for dust control
(D) Water use for approx. 85,000 cubic yards of concrete production
(E) Operational consumptive use = (B) + (C) + (D)
(F) Total lake evaporation from exposed water surfaces requiring augmentation by Lafarge
(G) Column (E) + Column (F)
(H) Total lagged mining depletions which reflect existing real time conditions at the Howe Pit Site
