II. Support Facilities - Rule 4.04 The location of support facilities at the Meadows No. 1 Mine are depicted on Map 7 of the approved permit application package. Support facilities remaining on the site include the guard shack, office trailer, truck scales, Yampa River bridge, conveyor gallery, coal reclaim tunnel, ventilation fan system, crusher, well house, and shop. The office trailer, truck scales, bridge, and shop will be left in place as requested by the landowner, and mandated by decree of the Routt County District Court on October 27, 1983. The operator has not yet provided the Division with a detailed reclamation plan for the remaining structures and facilities yard areas. Stipulation 13 has been imposed upon the Division's proposed decision to renew the permit. The requirement is as follows: Stipulation No. 13 WITHIN THIRTY (30) DAYS OF THE DIVISION'S PROPOSAL TO APPROVE THE MEADOWS N0. 1 MINE PERMIT, SUN COAL COMPANY MUST SUBMIT A TECHNICAL REVISION APPLICATION WHICH ADEQUATELY ADDRESSES AND RESOLVES THE CONCERNS RAISED IN THE DIVISION'S PRELIMINARY ADEQUACY REVIEW LETTER DATED APRIL 27, 1993. III. Hydrologic Balance - Rule 4.05 A. Ground Water Ground water occurs in both bedrock and alluvial aquifers in the mine area. Regional bedrock aquifers include the Trout Creek Sandstone, the Middle Sandstone, the Twentymile Sandstone, and the White Sandstones. Many other strata are also water-bearing. However, they either yield insufficient amounts of water to wells, or are not continuous through the basin and, therefore, cannot be considered regional aquifers. Post-depositional folding of these strata has resulted in the formation of several bedrock ground water sub-basins. Generally, these sub-basins constitute separate ground water basins with individual recharge and discharge areas. This tends to localize bedrock ground water and inhibit regional flow patterns. The Meadows Mine is located on the eastern flank of the Hayden Syncline, a sub-basin of the Sand Wash Basin. Currently, four other mines are at least partially located within the Hayden Syncline: the Seneca II, the Grassy Gap, Seneca II West, and tie Hayden Gulch Mines. All of the mines obtain coal from the Mesa Verde Formation. Operators at Meadows and Grassy Gap mined coals in the lower coal group, below the Trout Creek sandstone. The two Seneca mines obtain coal from the middle coal group, and at Hayden Gulch coals were mined in the upper coal group, above Twentymile Sandstone. 7ransmissivities of the bedrock aquifers are usually low. High yields are only obtained in wells completed in fracture zones. The
