Notes: Unit Transit Loss= 0.25% per mile
(A) Monthly Evaporation rates from previous AI CoSSP approvals Greeley Lease Transit Distance= 0.5 miles
(B) Estimated exposed groundwater acreage Greeley Lease Total Transit Loss= 0.13%
(C) Monthly Evap rate(Col A)multiplied by current monthly exposed surface area(Col B)
(D) Estimated production rate
(E) Assuming material is 2%water by weight;material is mined in a dewatered state and is not washed
(F) Estimated water needed for dust control on-site.
(G)Total Consumptive Use(CU)is Col C+Col E+Col F
(H) CU amount is lagged back to river using Glover equation. Lagged estimate includes past consumptive use at the East 8th Street Pit
(1) Lease from the City of Greeley
(J) Credit from the City of Greeley lease after transit loss is assessed
(K)Water Balance=(J)-(H)
