Notes:
[7] Based on information from Reese
[8] Equals Column [7] x # tons/yr.
[9] Equals Column [8] x 2000 x 0.04/62.4/43,560.
[10] Equals 1500 gal/day x number of operating days (20 days)/325851, during production months
[11] Equals Column [9] + Column[10]. Dust control water is pumped from open pits.
[12] Total Evaporative and Operational depleitons. Column[6], Table 1 + Column [11]
