Notes:
1.Percent of excavated material based on historical operations at pit.-Accounting values based on measurements of actual tonnage.
2.Total excavated material of 1600000 tons in 2016 and 1600000 tons in 2017,distributed per(1).
3.and 4.Projected tons of material washed and not washed based on historical operations at pit.Actual recorded values to be used in SWSP accounting.
5.Equal to 4%of washed material(3)+2%of material not washed(4).
6.Exposed surface area outside of lined areas.
7.Net evaporation based on gross evaporation(NOAA NWS-33)less 70%of average precipitation(see Table 17).
8.Equal to(6)a(7), Accountina values based on measurements of actual ice cover.
9.1 ac-ft in 2016 and 1 ac-ft in 2017.Distributed based on(1).
10.Equal to(5)+(8)+(9).
11.Equal to unlagged mining depletions(10),lagged back to South Platte River using AWAS program with following aquifer parameters:X=1200 ft;W=7996 ft;T=90000 gpd/ft,and S=0.2.
12.Dewatering at site only for bypass of precipitation inflows.
13.Equal to unlagged dewatering pumping(12),lagged back to South Platte River using AWAS program with following aquifer parameters:X=1200 ft;W=7996 ft;T=90000 gpd/ft,and S=0.2.
14.Equal to(11)+(12)+(13).Negative values(-)represent net depletions to river system.Positive values(+)represent net accretions to river system.
