Notes:
[11 Total sand and gravel production in tons.
[2]Total dust control water uses in gallons. Dust control water uses considered 1009'o consumptive.
[3]Total maximum exposed groundwater surface area in the pit.
[4]Water removed in mined material.Equal to 4%water by weight of material produced.
[5]Total dust control water uses in acre-feet. Equal to[2]/325851.Dust control water uses considered 1000 o consumptive.
[6]Required evaporative replacement based exposed water surface area.Equals exposed water surface area x 3.85 ft x monthly%.
3.85 feet=annual net evaporation rate at the site
[7]Total unlagged depletions requiring replacement. Equals[4]+[5]+[6].
[8]Total lagged depletion to the Arkansas River.Lagging method described in the SWSP renewal request.
[9]Percent days of call during the month.
[10]Replacement requirement equal to-[8]*[9].
[11]Consumptive use credit from 2 Rocky Ford Ditch shares.Negative values indicate non-irrigation season net return flow obligations.
[12]_� r, ._. l -"
[13]Remaining replacement requirement after accounting for credit/obligation from Rocky Ford Ditch shares and other replacement supply(not applicable for this SWSP period).
[14]Transit loss requirement for reservoir release to meet the remaining replacement requirement.
[15]Required release equals[12]+[13].
[16]Scheduled release of leased water for 22 West Pit.Released water includes 35 acre-feet per year through agreement with Aurora.
[17]Transit loss percent assessed on reservoir release during month.
[18]Transit loss volume of water assessed on reservoir release during month.
