Banks and Gesso, LLC Groundwater Monitoring 1. Five monitoring wells have been installed on the property. These wells will provide a baseline of groundwater depths/elevations in the area before ' mining, and during dewatering operations. 2. Applicant will take monthly groundwater measurements of these wells and continue until tYie end of the reclamation process. 3. Applicant agrees to measure nearby shallow wells, with the well owners permission, assuming reasonable access for measurement physically exists at each well facility. ' 4. Groundwater records will be maintained in the on-site office, and available for public reviev/ during normal business hours. ' Mitigation Program 1. Based on the groundwater measurements, the Applicant agrees to notify ' any well owner of significant groundwater drops due to mining, that may affect the performance of that well. A significant drop would be three feet lower than the seasonal low for a well. The intent is to notify the neighbor ' in advance of a potential problem, and begin working together on a solution. 2. The Applicant agrees to mitigate the temporary effects of the dewatering ' operations on tFle subject well, using reasonable and cost-effective methods. 3. Mitigation techniques may include providing water, if required, construction of .a recharge facility and conveying water to it, altering the mining and reclamation sequence in that particular area of the site, etc. Since the solutions tend to be unique to each well location, the Applicant prefers to reserie some flexibility in selecting the mitigation technique to be implemented. ' Consumptive Use of Water Consumptive use of water will be through dust suppression in the plant area, on ' the interior haul road, <Ind through evaporative loss from stockpiles and alluvial groundwater exposed due to mining. The total annual depletion of South Platte River water due to the:;e factors will be 30 acre-feet for the first year and 42.0 acre-feet per year for the remainder of the mining process. An annual accounting of the consumptive use of the mining operation's water needs is required to be submitted to the State as part of the Substitute Supply Plan. A more complete description of the consumptive use of water by this operation is contained in the "Temporary Substitute Supply Plan" which is will be submitted to the Colorado Division of Water Resources.
