<br />STATE OF COlORA00 FiC HPaD D. ~M. Gnvc mop III IIIIIIIIIIIII III <br />DEPARTMENT OF NATURAL RESOURCES <br />Harris D. Sherman. Executive Director ggg <br />MINED LAND RECLAMATION <br />723 Centennial Building, 1313 Sherman S[reet <br />Denver, Colorado 80203 Tel. (303) 839-3567 <br />Hamlet J. Barry, I I I, <br />Director <br />January 18, 1982 <br />TO: Dan Mathews <br />FROM: Roy L. Cox ,~ <br />1 <br />SUBJECT: Technical Adequacy Review of the Grand Mesa Coal Company, <br />Red Canyon No. 1 and No. 2 Mines Permit Application and <br />Responses, File No. C-034-81 <br />I have completed the technical adequacy review you requested on the ground- <br />water, water quality, monitoring and geology sections of the Red Canyon No. 1 <br />a and No. 2 mines. Permit Application and Responses to preliminary adequacy <br />questions. During this review, several serious concerns were identified. <br />Among the identified concerns are: 1) The on and off-site impacts of mining <br />activities on surface and groundwater rights; 2) The impacts of mining on <br />surface and groundwater supplies to an alluvial valley floor (AVF); and 3) <br />The impacts of mining on renewable resource lands (e.g., aquifers, areas fo:~ <br />recharge to aquifers, areas for agricultural production of food, and pasture <br />lands). These concerns arise from the sensitivity of the lands to be under- <br />mined to changes in the quality and quantity of ground and surface waters. <br />These concerns are not adequately dealt with within the hydrology sections of the <br />permit application, since they are not supported by enough site-specific data. <br />Also maps contained within the geology and hydrology sections lack legible contour <br />lines, stream channels, and lack critical information such as springs, irrigation <br />systems, some monitoring well locations and drainage system boundaries. Written <br />findings have to be made by the Division before issuing a permit. These findings <br />can not be made at this time given the information presented in the permit <br />application and the information available to the Division. The following findings <br />can not be made: <br />1) The applicant has provided to the Division adequate hydrologic information to <br />make an environmental assessment (Rule 2.07.6(2)(a)); <br />2) The applicant's proposed mining operation is designed to prevent damage to <br />the hydrologic balance outside the proposed permit area (Rule 2.07.6(2)(c)); <br />3) The applicant's proposed operation will not interrupt, discontinue or preclude <br />farming upon alluvial valley floors (Rule 2.07.6(2)(k)); and <br />4) The applicant has identified the extent to which the proposed mining activities <br />may proximately result in contamination, diminution or interruption of an under- <br />ground or surface source of water within the proposed permit and adjacent areas <br />for all legitimate beneficial use. If water rights will be impacted, the appli- <br />cant will provide an alternative water supply. <br />T.he Red Canyon No. 1 mine in the E-Seam and the proposed No. 2 mine in the I)-Seam, <br />will undermine a major aquifer in the area, the "Glacial-Alluvial Aquifer". This <br />aquifer is composed of over 250' of coarse grained unconsolidated deposits, and <br />
