<br />2012 Water Balance
<br />Loloff Pit Substitute Water Supply Plan
<br />All values In ac -ft unless noted
<br />Notes:
<br />(A) Monthly Evaporation rates from previous approvals.
<br />(B) Estimated exposed acreage when pumps are on = .23 acres when pumps are off 10.5 acres
<br />(C) Monthly Evap rate (Col A) multiplied by current monthly exposed surface area (Col B).
<br />(0) Estimated production rate for 2010.
<br />Unit Transit Loss = 0.25% per mile
<br />Platte River Power Transit Distance = 30.3 miles
<br />Platte River Power Total Transit Loss = 7.58%
<br />Graham Ditch Transit Distance =
<br />Graham Ditch Total Transit Loss = 1.08%
<br />4.3 miles
<br />Assuming 4% of water retained in product.
<br />Intermittent Fill Volume = (Volume of Mined Material) x (1- Porosity) - (Col E). Mine material volume estimated using assumed specific weight 125 lb/ft'. Porosity assumed to be 3o%
<br />Estimated water needed for dust control on -site.
<br />Total Consumptive Use (CU) is Col C + Col E + Col F + Col G.
<br />CU amount is lagged back to river using a 6o day SDF factor. Lagged estimate includes past consumptive use at the Loloff Pit
<br />Lease from Platte River Power Authority
<br />Credit from Platte River Power Authority lease after transit loss is assessed
<br />Lease from Graham Ditch Company
<br />Credit from Graham Ditch Company lease after transit loss is assessed
<br />Lease from City of Greeley to provide effluent from Wastewater treatment plant which is right in the vicnity of Loloff therefore no transit loss is assessed.
<br />Water Balance = (I) + (K) + (M) - (H)
