Stipulation No. 6 THE PERMITTEE SHALL SUBMIT AN ANNUAL HYDROLOGIC REPORT BY DECEMBER 1 OF EACH YEAR. THIS REPORT SHALL CONSIST OF AN ANALYSIS OF ALL MONITORING DATA COLLECTED THROUGH SEPTEMBER 30 FOR 1) SURFACE WATER, 2) GROUND WATER, 3) MINE INFLOWS, 4) CONSUMPTIVE USE OF WATER IN THE MINE, AND 5> MINE WATER DISCHARGES. THE REPORT SHALL CONTAIN AN ASSESSMENT OF THE IMPACTS OF MINING ON THE QUALITY AND QUANTITY OF GROUND AND SURFACE WATERS DURING THE PAST YEAR, AND AN ESTIMATE OF THE PROJECTED IMPACTS OF MINING IN THE FOLLOWING YEAR. THE HYDROLOGIC REPORT FOR 1983 IS TO BE SUBMITTED WITHIN 60 DAYS OF PERMIT ISSUANCE. With the acceptance of the above stipulations, the proposed operation is in compliance with the requirements of this section. VII. Alluvial Valley Floors - Rules 2.06.8 and 4.24 AVF Determination The applicant has provided the results of an alluvial valley floor field investigation in Volume 8 of the permit application. The extent of the study area is shown on Map I of Volume 8. It includes portions of the Williams Creek, Ward Creek, Cottonwood Creek, and Kiser Creek watersheds adjacent to the permit area. The mine itself is located between Ward Creek and Cottonwood Creek. The applicant has identified several areas of unconsolidated streamlaid deposits. The majority of this material occurs as mudflow fans, shown as Qaf on Map 7 of the addendum. There has been some discussion concerning whether or not these mudflow fans (alluvial fans) meet the geomorphic criteria for alluvial valley floors. The preamble to the OSM Alluvial Valley Floor Guideline (June 11, 1980) indicates that parts of alluvial fans should be considered for alluvial valley floor determination when they are integrated hydrologically with modern terraces. In this case, the fan deposits are integrated both hydrologically and agriculturally with the modern stream terraces, and should, therefore, be considered in the alluvial valley floor determination. The applicant has also identified four distinct river terraces south of the area which is covered by alluvial mudflow deposits (see Map 7 of Volume 8). The uppermost terrace (Q+4) appears to be part of a dissected pediment which occupies the topographic highs between the stream valleys. It is not a part of the valley bottom complex. The remaining terraces are topographically lower, and are part of the valley bottom complex. The applicant has also provided information concerning water availability for agricultural purposes. These studies focused on the Ward Creek and Williams Creek valleys since these areas may be affected by the proposed mining operations. _19_
