Blue Pit 112 Permit Amendment <br />z) The source of the water to be used by the Blue Pit Expansion is the Basin and <br />Spring Ditch. Also there are 2 wells on site which supply water to the concrete <br />plant and the shop. These items are shown on Map C -i. <br />3) The water supplied from the Basin and Spring Ditch as well as the wells on site <br />are not used for drinking water. Potable water is provided by bottled water. <br />4) The Basin and Spring Ditch only run during irrigation season. The well on site <br />is not affected by seasonal variations. During non - irrigation season, all water for <br />the operation comes from the wells. A majority of the water demands are during <br />irrigation season. <br />5) Water used in the material washing operations will be recycled through the <br />plant to reduce the annual amount of water used. Water recycling is currently <br />conducted at the Blue Pit. <br />6) A majority of the water consumption occurs during irrigation season. Washed <br />material is stockpiled through the winter to reduce winter water needs. <br />The determination was made in the decree of Appendix J that the mine will utilize 7.4 acre -feet of <br />consumptive use which was made available from the 1.o cfs that is the historic water right for the <br />property. This amount of water (7.4 acre -feet) at the mine has been sufficient for all consumptive <br />uses and since production is not changing for the 2014 amendment, the existing water rights are <br />sufficient. <br />Blue Pit May 2014 G -9 <br />
