-e- ~~~~, B. Surface Water Information The surface water information within the permit application is found in Sections 3.2 and 3.5; Appendices III-2, III-11 and III-12; Tables III-13 through III-17 and III-21 through III-22c; Figures III-17h through III-17t, III-23, III-24 and TII-25; and Maps III-14 and IU-9. A description of surface water occurrence, surface water monitoring and mining impacts on surface water within the permit and adjacent areas can be found in Section VIII, "Probable Hydrologic Consequences of Mining and Cumulative Hydrologic Impact Study" of this document. With the acceptance of the hydrologic stipulations, the Division finds this section in compliance for the Eagle No. 5 and No. 9 Mines. VII. Alluvial Valley Floors - Rules 2.06.8 and 4.24 The applicant has determined that alluvial valley floors exist along both the Yampa and the Williams Fork valleys within the permit and adjacent areas. This determination is based upon the fact that flood irrigated agricultural activities are practiced on unconsolidated streamlaid deposits along both rivers. The Division concurs with this determination. The boundary of the alluvial valley floors is shown on Map IV-8 of the permit application, Three alluvial valley floors have been identified, the Williams Fork alluvial valley floor, the Yampa River/Big Bottom alluvial valley floor, and the Yampa River/Round Bottom alluvial valley floor, A]luvial Valley Floor Exemption Mining operations that, in the year preceding August 3, 1977, a) produced coal in commercial quantities and were located within or adjacent to alluvial valley floors, or b) obtained specific permit approval from the State to conduct surface coal mining and reclamation operations within an alluvial valley floor are exempted, under Rule 2.06.8(5)(a), from the alluvial valley floor provisions prohibiting mining in or adjacent to certain alluvial valley floors. On November 12, 1980, Empire Energy Corporation submitted a request to exempt their existing and proposed mining operations from these alluvial valley floor provisions. (See Appendix IV-7 of the permit application.) After reviewing that submittal, the Division determined that both the Eagle No. 5 Mine and the Eagle No. 9 Mine were eligible for the exemption. Materials on file with the Colorado Division of Mines, "Operator's Monthly Coal Report" indicate that coal was produced in commercial quantities from the Wise Hill No. 5 mine (now called the Eagle No. 5 Mine) in the year preceding August 3, 1977. Specific permit approval was granted for the Wise Hill No. 9 mine (now called the Eagle No. 9 Mine) by the Colorado Mined Land Reclamation Board on March 24, 1977.
