Table G-1 - Permitted and Decreed Wells Within 600 Feet of Mining Limits Map Permit Structure Zip ID No ID Well Name Owner Address City State Code 3791 E 18' 1 102669-A W C Mathews Street Greeley CO 80631 2 118187-A Weld County P.O. Box 758 Greeley CO 80631 3 76222-F Weld County I P.O. Box 758 1Greeley I CO 80631 At the time of SWSP application/approval, a new gravel pit well permit will be applied for/obtained to include the evaporative and operational losses from the property. If the proposed use of groundwater at the DPG Mining site results in material injury to surrounding wells, J-2 Contracting Company will ensure that all necessary measures are taken to address the issues. Water Quality An NPDES permit will be obtained from the Water Quality Control Division at the Colorado Department of Public Health & Environment for the DPG Mining site prior to discharging any groundwater that is dewatered from the site. This permit will be kept current and amended as necessary to ensure that any water discharged from the site will meet the permitted water quality standards. Impacts to Groundwater/Hydrologic Balance J-2 Contracting Company will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. J-2 Contracting Company will construct these ditches/ponds in the locations where direct discharge to an existing adjacent irrigation lateral is not available to ensure that stabilized groundwater levels are maintained. They will discharge dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance to the surrounding land. Slurry wall liners are proposed around the individual phases and will likely be installed either shortly after mining has begun or prior to mining starting. The only phase that mining may start prior to the slurry wall installation being completed is Phase 1. To summarize the mitigation process, as each phase of mining/dewatering occurs it will draw down the surrounding groundwater level to some extent. J-2 Contracting Company will monitor the groundwater levels adjacent to mine as each phase progresses. If groundwater levels drop to a level that prevents an adjacent well from performing acceptably, according to that well's owner, J-2 Contracting Company will either implement a groundwater recharge ditch/pond near the well in order to raise the groundwater level in the vicinity of the well and hence return it's operation to acceptable standards, or will negotiate an agreement with that well owner to replace the well or provide replacement water via other means until the mining and reclamation activities are concluded. Groundwater wells that are not owned by J-2 Contracting Company (Figure G-1) are potentially located within 600 feet of the mining limits. The exact physical location of these wells will be determined during the SWSP and well permit application processes. If wells are found to be within 600 feet of the mining limits, J-2 Contracting Company will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that J-2 Contracting 111111111 J&T Consulting,Inc.
