These structures aze located outside of the calculated angle of draw from any of the planned five-(5) year (1993 - 1998) mining. Therefore, the structures are protected from any subsidence-induced damage. Oil Pipeline. Ahigh-pressure, oil pipeline owned by AMOCO Pipeline Company traverses the permit area from the southwest to the northeast, approximately paralleling County Road 107.

Renewable Resource Lands The following renewable resource lands have been identified within and adjacent to the permit area: • Alluvial Valley Floor • Yampa River • Williams Fork River • Sandstone Aquifers Alluvial Valle,, Fem. The river valley bottoms of both the Yampa and Williams Fork Rivers are classified as alluvial valley floors (AVF). The ground surface in these alluvial valleys supports sheep and cattle ranching operations. The direction of ground water flow in the alluvium is generally parallel with river valley trends as well as towards the river. A detailed discussion of the hydrologic characteristics of the alluvial valley floors is presented in Section 2.04.7, Hydrology [nformation. Yampa River. The Yampa River meanders across the permit area from the northeast to the southwest. The Yampa River is a snowmelt stream and is dependent on the winter snowpack for much of its annual flow. Runoff from thunderstorms accounts for its peak flow during the summer and fall months. A detailed discussion of surface hydrology is presented in Section 2.04.7, Hydrology Information. Williams Fork River. The Williams Fork River is a major tributary to the Yampa River. The Williams Fork River traverses the southern part of the permit area where it joins the Yampa River. The Williams Fork River is a snowmelt • stream and is dependent on the winter snowpack for a majority of its annual flow.
