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