8. Since the sediment load and settling characteristics of the mine discharge water is variable a <br />conservative educated estimate of the retention pond requirements was made. Operational <br />observations indicate that under normal circumstances adequate settling occurs within the first <br />two ponds provided the mine discharge is properly treated with coagulant. <br />9. The first pond in the series is intended to accumulate the vast majority of the sediment from the <br />mine discharge. Periodic sediment removal will be facilitated by temporarily diverting mine flow <br />directly to the second pond while the first pond is dewatered and sediment removed. <br />Minor Revision #162 (09/2014) <br />
