continue assessment of the groundwater geometry, static water level measurements
continue to be collected. Measurements, attached as Appendix 4 -3(b) and 4 -3c, indicate
spring rise in the perched water elevation. As discussed above, there is no identifiable
hydraulic connection between the water available in coals and in fractures or in springs
and seeps. There are no regional or widespread continuous aquifers in the permit or
adjacent areas, and consequently, piezometric maps cannot be developed. See Map 4 -3
for spring elevations and other water data. Hydro - geologically, the springs and seeps are
not connected (See logs and Map 4 -3). There is no correlation between the first water
samples and the ones submitted as additional information.
Monitoring of springs, seeps, and groundwater monitoring wells has continued since
permit issuance in accordance with the applicable monitoring program at any given time.
The current monitoring program was terminated in 2006 with the consent of the Colorado
Division of Reclamation, Mining and Safety. Hydrologic data has been complied in the
Annual Hydrologic Reports for the mine. These reports are submitted annually.
Information concerning the general geology and hydrology can be found in the following
public information which is available to the Division from other state and federal
agencies. Said information and data is hereby incorporated herein by reference.
