1.3 Impacts to groundwater <br />Adverse impacts to the local groundwater aquifer have not been observed or reported on the <br />Greeley 35th Avenue Mine. Adverse impacts are not anticipated to develop as a result of current or <br />future MM reclamation in the West Cell of the Greeley 35th Avenue Mine. GEI has modeled <br />current and post reclamation groundwater conditions at the 35th Avenue site utilizing Visual <br />MODFLOW (Version 2011. 1, U.S. Geological Survey (USGS) 2014), and the results indicate a <br />maximum dfawdewn- mounding of 2-.61_5 feet of groundwater impact adjacent to the south side of <br />the West Cell and a maximum - risedrawdown of 1.5 foot of groundwater impact adjacent to <br />the east side of the West Cell, with impacts lessening as the distance away from the cell increases. <br />The MODFLOW does not predicted dfewdeym any impacts for the north and west side of the <br />West Cell is , due to the proximity of the Cache ]a Poudre River. The <br />results are provided in MODFLOW Figures ] through 69. <br />1.4 Well Inventory <br />A well inventory for areas surrounding the Greeley 35th Avenue Property was conducted to <br />identify registered wells within 600 feet as required by the Colorado Office of the State Engineer <br />(SEO). GEI identified sr>Ffive domestic wells and five-three irrigation wells within 600 feet of the <br />Greeley 35th Avenue Property boundary, however, only two wells (noted below) are within 600 <br />feet of the arovosed Developed Water Storage. The wells are identified below: <br />Domestic Wells within 600 feet of Developed Water Storage <br />Permit No. 75772 <br />Owner — Robert Drewer <br />Rt 2 Box 180A <br />Greeley, CO 80631 <br />Location NE '/.
