shown on Map King I-004. This well will be used as a water monitoring station
<br />because none of the other wells listed in this area are active. Analysis will be
<br />M performed quarterly and results will be included in the annual hydrology report
<br />submitted to the Division. Water will be sampled for parameters listed in 2.04.7,
<br />page 1 with the exception of ADepth to Water@ as this is a sealed well with no
<br />practical means of measurement. (See Ground Water Monitoring, 2.04.7 page 1).
<br />The Wiltze Well, located in the alluvial valley floor Adownstream@ from the
<br />west sedimentation pond is also used as a water monitoring station. Analysis will be
<br />performed quarterly and results will be included in the annual hydrology report
<br />submitted to the Division. Water will be sampled for parameters listed in 2.04.7,
<br />page 1 (See Ground Water Monitoring, 2.04.7 page 1).
<br />The Hay Gulch ditch, upstream from the mine area, will be sampled at the
<br />beginning of irrigation season in the spring and at the end of irrigation season in the
<br />fall to provide baseline data. Sampling will begin during spring of 1997 and
<br />continue through fall of 1998. Analysis results will be included in the annual
<br />hydrology report submitted to the Division. Water will be sampled for parameters
<br />listed in 2.04.7, page 1 (Ground Water Monitoring).
<br />All wells shown in Sections 28, 29, and 32, T35N R 11 W and Section 36, T35N
<br />R12W lie within the Hay Gulch drainage, topographically below the coal seam
<br />outcrop. There will be no Hydrologic effects on these wells or points of diversion.
<br />Two wells supply fresh water to the mine. One of these is located in the
<br />meadow of Hay Gulch off the permit site. A water right agreement for use of the
<br />meadow well is included (See Appendix 2(5)). Water from the two wells is pumped
<br />into the mine via one four inch water line. All water lines are buried beneath the
<br />frost line. This water supply is a result of a cooperative effort between the surface
<br />landowner, National King Coal, LLC and the Soil Conservation Service for
<br />incorporation into a field drainage program. Without this arrangement, water
<br />gradually builds up on the surface of the field denying the rancher access and
<br />utilization of his land.
<br />There will be no impacts downstream of Pine Gulch due to subsidence related
<br />depletion of flow. Subsidence could be caused by pillar extraction during retreat,
<br />but is not planned. National King Coal, LLC has submitted a mining plan showing
<br />elongated pillars supporting all entries under the Pine Gulch drainage system.
<br />These pillars will not be extracted on final retreat, thereby providing perpetual
<br />stability for the Pine Gulch drainage and preventing potential damage to the
<br />hydrologic balance outside the permit area. Map King I-012 shows the drainage
<br />basin of Pine Gulch above those points proposed to be .crossed by mine development
<br />is included. The total area of this drainage is approximately 365.5 acres.
