<br />2013 Water Balance
<br />Loloff Pit Substitute Water Supply Plan
<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 6).
<br />(D) Estimated production rate for 2010.
<br />(E) Assuming 4% of water retained in product.
<br />(F) Intermittent Fill Volume = (Volume of Mined Material) x(1 - Porosity) - (Col E). Mine material volume estimated using assumed specific weight 125 lb/ft 3 . Porosity assumed to be 3o%
<br />(G) Estimated water needed for dust control on -site.
<br />(H) Total Consumptive Use (CU) is Col C+ Col E + Col F + Col G.
<br />(I) CU amount is lagged back to river using a 6o day SDF factor. Lagged estimate includes past consumptive use at the Loloff Pit
<br />(J) Lease from City of Aurora
<br />(K) Credit from City of Aurora lease after transit loss Is assessed
<br />(L) Lease from Graham Ditch Company
<br />(M) Credit from Graham Ditch Company lease after transit loss is assessed
<br />(N) 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 />(0) Water Balance = (I) + (K)+ (M) - (H)
