3 gallons of water per ton of Asphalt.Therefore,the estimated annual production of 150,000 Tons of asphalt
<br /> will require 1.38 AF of water each year during 2017 and 2018. Table 5 shows the estimated monthly
<br /> distribution of asphalt production and associated water uses.

<br /> 2.2.7 Water Losses due to Dust Control, Vehicle Washing, Indoor Uses, and Landscape Irrigation
<br /> Water used for dust control,vehicle washing, indoor uses,and landscape irrigation is metered. RESOURCE
<br /> estimated the amount of water required for these uses based upon water meter records available for the
<br /> 2009-2016 period. Operations for dust control within MCR's roads are considered 100% consumptive.
<br /> RESOURCE estimated that losses due to dust control operations for 2017 and 2018 will total 4.75 AF per
<br /> year. Water consumption due to vehicle washing at MCR (different than concrete truck washing) was
<br /> estimated at 0.15 AF per year. The consumptive use of water utilized for indoor uses at Everist's office and
<br /> shop is estimated at 10%. Based upon historic records of indoor water uses, depletions corresponding to
<br /> indoor water uses are estimated at 0.05 AF per year. Lastly, the consumptive use of water utilized for
<br /> landscape irrigation is estimated to average 1.83 AF per year. Landscape irrigation consists of a 0.25-acre
<br /> lawn, irrigated by sprinklers, and approximately 0.75 acres of trees watered by a drip-irrigation system.
<br /> Table 6 displays the estimated monthly distribution of these water depletions for 2017 and 2018.
<br /> 2.2.8 Well Permits Associated with Project Consumptive Uses
<br /> As required in the General Guidelines for SWSP, Everist holds the well permits necessary for its MCR
<br /> operation. On January 19, 2017 a gravel pit well permit application was submitted to the Division of Water
<br /> Resources to add dewatering as an authorized use(copy of the application is included in Attachment D).
