Annual Precipitation inches -Based on Western Regional Climate Center Fort Collins,CO Station(050035)
Gross Annual Evaporation= inches -Taken from NOAA Technical Report NWS 33
Notes-
(A)Based upon General Guideline,for Subaniure if(Iter Supply Plans for Sand and Gravel Puts
(B)Gross lake evaporation=(A)*(Gross Annual Evaporation 112).
(C)Estimated using annual precipitation and monthly distribution of precipitation from the Western Regional Climate Center-Fort Collins,CO(050035)
(D)Effective precipitation=0.7*(C):12.
(E)Net lake evaporation from exposed water surfaces=(B)-(D),there is no evaporation December-February due to below-freezing average monthly temperatures.
(F)Net exposed surface area calculated from dewatenng Cells 3 and 4.After July there is projected to be no exposed groundwater at the site due to completion of mining in Cell 3 and the completion of lining of Cell 5.Cell 4 dewatennc
will begin around August
(G)Total lake evaporation from exposed water surfaces=(E)*(F).
(H)Crashed aggregate estimates provided by Martin:Marietta.
(1)Washed aggregate estimates provided by Martin Marietta.
(J)Water retained in product equals 4%of total weight of washed aggregate produced and 21,0 of total weight of crushed aggregate produced
(K)Dust control water volumes provided by Martin Marietta.All dust suppression water in 2014 is projected to be supplied from the Home Office Pit
(L)Equals(J)+(K).
(M)Equal%(G)+(L).
(G)Lagging calculations were based on the following parameters.
Distance from stream=2,000 ft,Transmissivity=160,000 gpdi t,Specific Yield=0 2,No-flow Boundary=3,000 ft
