In the extremely unlikely event that groundwater was ever encountered during the 13 feet <br />temporary operation in Phase 1, and in subsequent phases, Haldorson commits to <br />covering any wet azeas with 5 feet minimum of overburden/topsoil and forgo any future <br />mining in that azea. <br />Summary of Additional Reasons Based on January 2004 Data and Investigations <br />10) Water well drilling confirmed the appreciable depths of gravel within Phases 1 <br />through 4 of the project. <br />11) Sieve Analyses and Percolation Testing confimed that the gravel offers almost no <br />resistance to water movement. <br />12) Additional geology investigation (supported by well drilling data) which shows a <br />shale ridge along the southwest comer of the permit area trending northwest to the <br />southeast, preventing almost all groundwater from entering the site. <br />13) Letters from various people supporting the fact that no water was encountered at <br />shallow depths in the surrounding pits, even during imgation season. <br />All of the information presented in the December 24, 2003 Report has been strengthened <br />and confirmed by the additional work done in January 2004. The fact that so little <br />imgable area can infiltrate water to the Haldorson site, combined with the fact that the <br />gravel is proven to be extremely permeable and the gravel depths in Phase 1 aze <br />confirmed to be greater than 60 feet, this rs overwhelming evidence that it is extremely <br />unlikely that groundwater will be encountered in Phase 1 to a depth oJat least 40 feet. <br />As stated eazlier, this request is for 13 feet. I believe, as a registered professional engineer <br />in the State of Colorado, with 23 years of mining, reclamation and hydrology experience <br />in this State, that the science is very cleaz and that to deny mining to the depth of 13 feet <br />in Phase 1 would be an extreme injustice to the applicant, Mark Haldorson. <br />p0 R E~I~T~ <br />~~ <br />20338 ~~ '/aS/9~f <br />
