F. Transfer of Wells <br />The Division proposes to approve transfer of a monitoring well located in the SE'/a of <br />Section 30, T 34 N, R 4 W, N.M.P.M.. This proposal is based on the fact that a well <br />permit has been obtained from the State Engineer, and written requests for the transfer <br />have been received from the applicant and [he surface owner. Upon final bond release, <br />the wells will be transferred over to the landowner (4.05.14(3)). <br />G. Discharge of Water into an Underground Mine <br />No discharge of surface water into an underground mine opening occurs presently nor <br />during [he operation of the Chimney Rock Mine in years past. (4.05.16 and <br />4.05.3(1)(f)) <br />H. Probable Hydrologic Consequence <br />The site is an inactive former open pit coal mine. Surface reclamation of the site has <br />been completed and the pits backfilled. Data from water samples obtained from the <br />wells and surface water stations within and outside of [he permit area have indicated <br />little effect on the waters in the azea. Data from the wells and surface sampling stations <br />is reported in the Annual Hydrologic Reports. Future impacts could be related to the <br />infiltration of surface and groundwater into the backfilled pit areas. Since the areas <br />have been disturbed, the transmissivity of these areas is anticipated to be higher than <br />the surrounding areas. <br />Alluvia[ Aquifer mid Surface Water Impacts <br />An alluvial aquifer associated with Stollsteimer Creek has a high transmissivity rate and <br />is unconfined. Possible impacts to this aquifer would be associated with the infiltration <br />of lower quality water from the pit areas, effects from the dewatering conducted in the <br />area, and water quality deviations caused by surface infiltration of lower quality runoff <br />water. <br />The preferential flowpath of materials from the filled pits would tend to be horizontal <br />with discharge into the alluvial material. This is indicated by the difference in the <br />relative horizontal to vertical permeability of the formation, the shales that exist <br />between the pit areas and the sandstone, and the distance to the discharge point in the <br />alluvium. <br />Calculations indicate that the velocity of ground water movement through the Fruitland <br />Formation is adequate for infiltration to have taken place since the time of pit <br />backfilling. The pit in this area was backfilled in 1985; therefore, degradation to the <br />water quality or quantity in the area would have apparently occurred prior to the <br />present. <br />
