Accounting values based on measurements of actual Ice cover. 9.Equal to(6)-(7)+(8). 10.1 ac-ft in 2016 and 1 ac-ft in 2017.Distributed based on(1),and included as part of dewatering(16). 11.Percent of concrete production based on historical operations at Rinn Valley permit area:Accounting values based on measurements of actual production. 12.Total concrete production of 80325 cubic yards in 2016 and 85000 cubic yards in 2017,distributed per(11).Concrete plant scheduled to move from Rinn Valley permit area on or about 4/1/2016 13.Equal to(12)'50 gallons per cubic yard/325851,and included as part of dewatering(16). 14.Equal to(5)+(9).Dust control(10)and water used for concrete production(13)comes from pumping for dewatering(16).Therefore,the water for dust control and concrete production are removed from the dewatering amount returned to river,as calculated in the net depletions(18). 15.Equal to unlagged mining depletions(14),lagged back to St.Vrain Creek using AWAS program with following aquifer parameters:X=2210 ft;W=2262 ft;T=72300 gpd/ft,and S=0.2. 16.Based on average pumping over last year of 660 gpm recorded at site. 17.Equal to unlagged dewatering pumping(16),lagged back to St.Vrain Creek using AWAS program with following aquifer parameters:X=2210 ft;W=2262 ft;T=72300 gpd/ft,and S=0.2. 18.Equal to(15)+(16).(17)+(10)+(13),since dust control and water for concrete production 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.
