Sand and Gravel Mine near Montrose, Colorado, <br />we would like to add an additional commitment regarding the dispute over the mine's <br />potential to encounter groundwater in Phase 1 of the operation. Due to the limited <br />recharge area above the pit, the confirmed thickness of the gravel, high percolation <br />rates, lack of Water in other nearby pits, etc., we aze so confident that groundwater will <br />be a non-issue that we will commit to stopping mining in any area of Phase 1 where a <br />nearby monitor well shows water within 25 feet of the surface at any time. Therefore, <br />using the 4 existing monitoring wells in each approximate corner of Phase 1, if the <br />southwest well shows water at 24' from the surface, the southwest quarter of the phase <br />will cease mining. If the southwest and southeast wells show water within 24' of the <br />surface, then the entire south r/z of the phase will stop mining. Keep in mind that we <br />are only proposing to mine to a depth of 13' for the initial year while the well <br />monitoring is being done. CDMG will be welcome to conduct their own evaluations of <br />any well on site at any time. <br />Let me know if you have any further questions <br />...~ ,.,• <br />. o~ ,t ,-- , ..... <br />*- g' 'r: c":: <br />i' <br />Thanks. <br />Sincerely\G~~~~J """ <br />a <br />Gr~wicki, P.E. <br />Greg Lewicki and Associates <br />cc: Mark Haldorson <br />
