This results in <br />7.2 gallons of water per ton of coal leaving the property or <br />being lost to the drainage in the area. The mine will be pro- <br />ducing 200,000 tons per year at maximum production resulting <br />in approximately 180 gals./hr. being lost. This is equal to <br />4.8 acre feet/year. , <br />The sediment pond sizes are small enough that evaporation from <br />the ponds would be negligible. <br />The source of water for an augmentation plan to replenish the <br />water lost through the system is the Harvey Gap or Grass <br />Valley Reservoir. Shares of irrigation water are available <br />for purchase. <br />Current production levels of 200 tons per day result in 1.6 <br />acre feet of water lost in the system. Eastside does not pro- <br />pose to buy any shares at this time due to the low amount of <br />water lost. <br />Sincerely, <br />f'I ~.. .~ <br />Stephen Sel~ <br />General Manager <br />SS/mr <br />
