Second Submittal <br /> impacts. Similarly, we considered a mound (shown as negative value contours on the <br /> figures) of two feet or more to indicate areas where a potential may exist for increases in <br /> groundwater levels that could pose an issue. This value was chosen because the standard <br /> deviation was 2.1 feet,meaning predicted values above this become statistically significant <br /> in terms of potential impacts. <br /> 5.1 Mining Plan—Phases 1 through 5 <br /> Figure 16 through Figure 20 display predicted drawdowns at the ends of Phases 1 through <br /> 5,respectively. As the simulation moves through the phases,the areas of greatest potential <br /> impact (considered to be a drawdown of 5 feet or more and mound of 2 feet or more) are <br /> clearly seen. The potential for'impacts progresses from the south side of the Site to the <br /> north over the 10-year model timeframe. <br /> The largest off-site drawdowns occur from the mining north of the Little Cache la Poudre <br /> ditch. No wells are known to exist in this area north of the Site. The most significantly <br /> impacted wells are those in the"enclave" at the south side of the mine (the Cherry and the <br /> West wells). Although the Plantorium Greenhouse and Nursery did not respond to <br /> Telesto's questionnaire, we know that they have an irrigation well used to water their <br /> greenhouse plants. The Plantorium is inside the five-foot impact zone during the end of <br /> the first half of Phase 1. These three wells may require mitigation. <br /> 5.2 Mine Plan—Reclamation <br /> Figure 21 shows the model-predicted drawdowns after reclamation is complete. No off- <br /> site drawdowns greater than 5 feet are predicted. The largest is 3 feet in the enclave area. <br /> Three feet is statistically significant in this model, thus, that is one area to provide <br /> monitoring and mitigation if necessary after mining. The model predicts mounding in the <br /> statistically significant range up to approximately 370 feet west of the western Site <br /> boundary. <br /> Loveland Ready-Mix Concrete 18 Telesto Solutions,Inc. <br /> 20180112 gm=I%a(mtudy_2nd.bnun.d do�x January 2018 <br />
