The clay liner will be installed <br />each year. Therefore, in an area <br />the side slopes will be sealed <br />prevented from flowing into the <br />completed, the entire perimeter <br />groundwater will be allowed to lea <br />as the mining progresses <br />that is previously mined, <br />and groundwater will be <br />pit. When the pit is <br />will be sealed and no <br />k into the hole. <br />2. In order to limit the area of dewatering, the mine has been <br />segregated into two cells. When the mining in Cell A has <br />been completed and moved into Cell B, Cell A can be <br />completely sealed off. This will act as a further barrier <br />for seepage into Cell B. <br />3. To preserve the integrity of the water flow in the channel <br />of the South Platte River, a 100 foot setback will be placed <br />for mining next to the river. In addition, the low dike <br />along the west property line will be preserved. <br />4. In order to $nderstand how the groundwater will behave <br />during the mining operation, C & M proposes to monitor three <br />nearby wells. By monitoring the wells we can predict how <br />the water table will behave and anticipate how much it could <br />drop during the various seasons of the year. The three <br />wells to be monitored are the following: <br />1. The well marked PP on our well map which is the well <br />accompanying the ready mix concrete plant. <br />2. The well marked AE which serves the house on the <br />processing site. <br />3. A selected well in the northwest quarter of the <br />northeast quarter of Section 31. <br />During the initial dewatering part of the mining operation <br />in Cell A, these wells will be monitored once every two <br />weeks. After this initial period, we should have a good <br />understanding of how the water table will behave and <br />monitoring can occur thereafter at one month intervals. Our <br />studies and experience predict that the dewatering will not <br />dry up any wells. If any wells are impacted to this extent, <br />C & M Companies will take measures to replace water for <br />those well owners. <br />Water Usaae <br />Water consumption from the mining operation will come from the <br />following: <br />G-3 <br />
