Notes:
1.Percent of excavated material based on historical operations at site.-Accounting values based on measurements of actual tonnage.
2.Total excavated material of 380000 tons in 2016 and 0 tons in 2017,distributed per(1).
3.and 4.Projected tons of material washed and not washed based on historical operations at site.Actual recorded values to be used in SWSP accounting.
5.Equal to 4%of washed material(3)+2%of material riot washed(4).
6.Exposed surface area outside of lined areas.
7.Net evaporation based on gross evaporation(NOAA NWS-33)less 70%of average precisiteation(see Table 17).
8.Equal to(6)'(7). Accounting values based on measurements of actual Ice cover.
9.1 ac-ft in 2016 and 0 ac-ft in 2017.Distributed based on(1).and included as part of dewatering(15).
10.Percent of concrete production based on historical operations at site:Accounting values based on measurements of actual production.
11.Total concrete production of 4675 cubic yards in 2016 and 0 cubic yards in 2017,distributed per(10).Concrete plan(scheduled to move to Firestone Resource site on or about 4/1/2016
12.Equal to(11)'50 gallons per cubic yard/325851,and included as part of dewatering(15).
13.Equal to(5)+(8).Dust control(9)and water used for concrete production(12)comes from pumping for dewatering(15).Therefore,the water for dust control and concrete production are removed from the dewatering amount returned to river,as
calculated in the net depletions(17).
14.Equal to unlagged mining depletions(13),lagged back to St.Wain Creek using AWAS program with following aquifer parameters:X=715 ft;W=4173 ft;T=125000 gpd/ft,and S=0.2.
15.Based on average pumping over last year of 330 gpm recorded at site.
16.Equal to unlagged dewatering pumping(15),lagged back to St.Wain Creek using AWAS program with following aquifer parameters:X=715 ft;W=4173 ft;T=125000 gpd/ft,and S=0.2.
17.Equal to(14)+(15)+(16)+(9)+(12),since dust control and concrete water comes from dewatering pumping that does not return to the river.
Negative values(-)represent net depletions to river system.Positive values(+)represent net accretions to river system.
