response from the DRMS. As a response to my complaint, Eric Scott finally provided the correct <br /> data and the 15 month baseline measurements will not be completed till this fall. <br /> Why did Peter Hayes deny the damages to the Koehler wells in his letter dated January 27th, <br /> 2020 without any data and without any"Direct Observation"? The Operator response " the <br /> Koehler owned groundwater wells have returned to the historic groundwater elevation <br /> following the completion of the Loloff Mine slurry wall in 2017."The Koehler wells were <br /> measured the very first time in September 2019. <br /> 13. Please note the Division will require Loloff Construction to mitigate all impacts <br /> to permitted wells affected by the dewatering activities, not just the wells <br /> within 600 feet of the mining limit. <br /> Response: <br /> Loloff Construction, Inc. understands that if wells outside 600 feet of the mining limit <br /> are proven to be affected by the mining operation dewatering that Loloff <br /> Construction, Inc. would be required to mitigate the impacts. <br /> 16. The Operator states should levels in the existing wells change by 2-4 feet then <br /> Loloff Construction, Inc. will mitigate by recharging at locations along the pit <br /> to increase the levels of the groundwater so that the impact from dewatering is <br /> minimized. Please provide justification for the proposed 2-4 feet trigger. <br /> Typically, a trigger point of 2 feet change from historic ground water levels is <br /> acceptable. The Operator must explain any mitigation measures to be <br /> implemented and trigger points that would put mitigation measures into effect <br /> if the recharging method of mitigation is not effective. <br /> Response: <br /> The Operator is fine with changing the trigger point from 2-4 feet to 2 feet. Other <br /> mitigation measures that may be necessary if the recharging method is not effective <br /> would be (1) working with the well owners that are affected to re-set their existing <br /> pumps to a lower level in order to mitigate any flow impacts to the existing well(s); <br /> (2) if the method in (1) is not effective then drilling a new well or deepening the <br /> existing well or providing water service from the City of Greeley or North Weld <br /> Water. <br /> 5 <br />
