c. Dust Suppression Water Use: Water is used, <br />principally in the summertime months, for dust suppression on <br />mine haul roads. The number of truck loads of water used for <br />dust suppression, and the volumetric capacities of the trucks, <br />will be recorded to calculate the total volume of water used on a <br />monthly basis for dust suppression. Dust suppression use of <br />water is 100$ consumptive. <br />d. Storage of Water and Evaporation Loss: The <br />storage structures proposed in paragraph 7 will provide <br />augmentation water to the stream system for evaporation losses in <br />these structures. The monthly pan evaporation data which will be <br />used to estimate evaporation is presented in Exhibit F. These <br />pan evaporation data will be used, times a factor of 0.7, to <br />account for monthly evaporation from the pond surfaces. The <br />surface areas of each of the storage structures shall be <br />determined from elevation-area capacity curves for that <br />structure. <br />e. water Shinned in Coal: There is a certain amount <br />of water added to the coal that is processed and shipped off <br />site. The amount of moisture added to the coal before shipping <br />is estimated based upon the moisture added value of 0.34 percent, <br />derived by the Internal Revenue Service for calculating black <br />lung assessment. The formula presented in Exhibit E takes the <br />tonnage of coal shipped at a moisture content of 0.34 percent and <br />converts that value to acre feet. <br />11. Accounting for Augmentation Plan: <br />water being supplied for these mine uses will be <br />measured on a monthly basis using flow meters at each point of <br />diversion. Staff gages will be installed in each storage <br />structure so that the gage can be related to the elevation-area- <br />capacity curve to calculate the evaporation rate. The staff gage <br />readings will also be used to calculate the volume of water <br />released from the storage structures for augmentation purposes. <br />kpplicant shall prepare and submit accounting forms monthly to <br />the Division Engineer and/or water Commissioner showing the <br />operation of the augmentation plan. Applicant proposes to use <br />the form attached as Exhibit D at the initiation of the operation <br />of this plan. Alterations to this form will be made as required <br />and as approved by the Division Engineer, without the <br />modification of the decree. Such accounting shall also be <br />provided monthly upon request to any party to this case. Such <br />forms shall be in a format acceptable to the Division Engineer <br />and shall include the following data: <br />a. Amount of water used for commercial water use and <br />truck washing. <br />b. Amount of water used in mine ventilation system. <br />-16- <br />
