Gross Exposed Water Surface 0.43 acres within current petntit boundary prior to August 2014
Gross Exposed Water Surface 0.00 acres within current permit boundary after August 2014
Annual Precipitation= 15.5 inches -Based on Western Regional Climate Center Fort Collins,CO Station(050035)
Gross Annual Evaporation= 38 inches -Taken From NOAA Technical Report N\US 33
Notes,
(A)Based upon General Guidelines jiir Stlbsnitite Wetter Supp/v Plans for Stind and Gravel Pils
(B)Gross lake evaporation=(A)"(Gross Annual Evaporation 1 12).
(C)Estimated using annual precipitation and monthly distribution of precipitation from the Western Regtonal Climate Center-Fort Collins,CC)(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 dewatering Calls 3 and 4.After Julv there:it projected to be no exposed gmundwater at the site due to completion ofmming in Cell 3 and the completion of lining of cell 5.Cell 4 dewatering
will begin around August.
(G)Total lake evaporation from exposed water surfaces=(E)"(F).
(H)Crushed 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 2%of total weight of crushed aggregate produced
(K)Duvt control water volumes provided by Martin Marietta.All duct suppression water in 2014 iv projected to be supplied from the Home Office Pit.
(L)Equals(J)+(K)
(M)Equals(G)+(L).
(G)Lagging calculations were based on the following pammeters-
Distance from stream=2.000 fl,Trnsmissivily=160,000 gp(vtL Specific Yield=0.2.No-flow Boundary=3.000 ft
