Although CWI feels the existing studies including <br />aerial photographs are adequate to characterize these lands, the Division <br />disagrees and feels field verifications are needed. Therefore, the following <br />stipulation is imposed. <br />Stipulation No. 28 <br />CWI SHALL COMPLETE THE ON-THE-GROUND FIELD VERIFICATIONS OF SURFACE <br />WATER RESOURCES ON THOSE LANDS FOR WHICH RIGHT OF ENTRY HAS NOT BEEN <br />OBTAINED. THE RESULTS OF THE SURVEY SHALL BE APPROVED BY THE DIVISION <br />PRIOR TO CWI UNDERMINING OR OTHERWISE AFFECTING THESE LANDS. <br />On-going monitoring consists of eleven surf <br />are monitored monthly for field parameters, <br />for ma,)or cations and anions.

To verify that no water will be lost when the Overland Ditch <br />diversion is used, the Division requests the following stipulation. <br />Stipulation No. 31 <br />CWI SHALL SUBMIT A PLAN TO MONITOR WATER QUANTITY CHANGES AS A RESULT OF <br />CHANGING THE OVERLAND DITCH POINT aF DIVERSION TO WEST ROATCAP CREEK <br />WITHIN THIRTY DAYS OF PERMIT ISSUANCE. <br />With acceptance of the above stipulations the information has been reviewed <br />and found to be in compliance with the requirements of this section. <br />VI. ALLUVIAL VALLEY FLOORS (2.06.8, 4.24) <br />The discussion of alluvial valley floors can be found on pages 5-6, Section <br />2.06 of Volume 1 and in the AVF Appendix, Volume 4. <br />Identification of Alluvial Valley Floors <br />The general area in which the Orchard Valley Mine is situated contains several <br />deposits of alluvium. These alluvial deposits are derived from three <br />sources: 1) Flood-plain alluvium (Qal) along the North Fork of the Gunnison <br />River; 2) Valley-fill deposits (Qvf) along a portion of Steven's Gulch; and <br />
