Page 2 of 2 <br />The vegetative cover is described as excellent and no problems are reported with regard to erosion or <br />stability. The pond has received minimal inflow since it was last cleaned in 2010. <br />No inspection report of pond 001 is included. This report should be forwarded to the Division. <br />In the West Portal area containments 1 and 2 are both reported as dry with excellent vegetative cover, <br />and plenty of sediment storage capacity. <br />At the bottom of the RDA, containments 5 and 4 (or N and SE), are both described as having some <br />erosion forming gullies and significant sediment accumulation. The gullies should be monitored and <br />repaired if necessary, and the sediment should be cleaned out. No problems were observed with <br />containment 3 (or SW). <br />Finally, rule 4.05.9(17) requires that copies of impoundment inspection reports are retained at the mine <br />site, and that they are submitted to the Division on a quarterly basis. We received copies of reports from <br />Q 1, 2013 the day after we received those from Q4, 2012, which negates the value of the quarterly <br />reporting somewhat. <br />Sincerely, <br />Leigh Simmons. <br />Environmental Protection Specialist <br />
