<br />As material is excavated, it will be washed on site. The water retained in this material is <br />considered as consumptive use. The anticipated amount of material that will be mined and <br />washed each year is estimated at A00,000 tons. Assuming 4 percent moisture content by weigh[ <br />as suggested by the State Engineer's Office, the total annual depletion due to water retained in <br />product is 11.8 acre-feet. <br />In addition, water use at the site will include dust control. This is water applied to haul roads and <br />stockpiles. It is estimated that one load from a 3000-gallon capacity water truck (Monday <br />through Friday) for nine months is required for dust control. This results in a consumptive use of <br />1.8 acre-feet per yeaz. <br />The total annual consumptive uses associated with the mining operations are as follows: <br />Evaporation 15.1 acre-feet <br />Moisture Retained in Product 11.8 acre-feet <br />Dust Control 1.8 acre-feet <br />Total 28.7 acre-feet <br />Water Rights <br />The operator of the site controls 30 shares of the William R. Jones Ditch and 5 shares of the <br />Whitney Ditch that were historically used for irrigation on the site, The proposed mining <br />operation will include all the area historically irrigated with these shares. Due to the dry-up of the <br />historically irrigated lands, the ditch shares will be made available for stream depletions due to <br />the mining operation. <br />The William R. Jones Ditch shares yield approximately 6.5 acre-feetrshare and the Whitney Ditch <br />shares yield approximately 33 acre-feedshare. The combination of the water rights will supply <br />approximately 360 acre-feet of replacement water on an annual basis. <br />The William R. Jones Ditch shares and the Whitney Ditch shares will be used to replace out of <br />priority stream depletions during mining. An application to temporarily change the use of the <br />Jones and Whitney shares from agricultural use to augmentation will be submitted to the State <br />Engineer's Office. The reclamation augmentation requirements will also be mitigated with the <br />Whitney and Jones Ditch shares. <br />Surrounding Water Rights <br />Exhibit G-1 shows the permitted and/or adjudicated water rights within one half mile of the site. <br />Well and water rights tabulations from the State Engineer's Office were used to locate the <br />surrounding wells and water rights as shown in Exhibit G-1. <br />River View Resource, CAMAS ColornAo, /nc. <br />OMC //1 Permi! <br />Page lI <br />
