Notes:
(1)Total material mined(no mining will occur during 2014-2015 SWSP)
(2)Water retained in product calculated as 4%of aggregate production per SB 89-120
(3)Water used for dust control(no dust control is planned for the Howe Pit Site during the SWSP renewal period)
(4)Water used for concrete batching(no concrete batching will occur during 2014-2015 SWSP term)
(5)Operational consumptive use=(2)+(3)+(4)
(6)Evaporative losses replaced by Denver Water
(7)Total consumptive use=(5)+(6)
(8)Reflects lagged depletions due to evaporation,operational uses and past mining activities at the site based on Glover analysis
using following parameters:
X= 2,400 ft
T= 45,000 gpd/ft
S= 0.2
W= 5,900 ft
(9)Reflects lagged depletions due to evaporation,operational uses and past mining activities at the site based on same parameters
