Maintenance items identified during inspection: • Please address the constructed berm in the southern segment of Diversion 5 -D2. The land to the west appears to have been used as a borrow area to construct a land bridge across the diversion channel, precluding flow through this diversion. This may be remedied by clearing the berm from the channel, rerouting the flow around the berm, or placing a culvert to allow flow directly through the channel. Placing a culvert would require a Technical Revision application. • Minor tree debris is beginning to accumulate in Diversion 5 -D2 and should be monitored or removed before it becomes a problem. • Please clean out the following culverts: 28 (north side is % full), 34, 48, 63 (east side is blocked), the blocked discharge culvert from Pond 5 -P3. • Rocks are accumulating in the #5D (Mine 5 dewatering, outfall 003) discharge flume. Although water is no longer being pumped from Mine 5, the outlet should be maintained to allow flow as designed. • Animal burrows were noted in several pond embankments. This is a standard problem at this site and should be monitored / repaired as usual. • Please update mine ID signs at entrances to the site (Rule 4.02.2). The DRMS permit number is printed as "C- 081 -044" rather than the most appropriate "C- 1981 -044" or acceptable "C -81- 044." High quality stickers may be used to update the permit number rather than replacing the signs. • Two markers on topsoil stockpiles near the waste disposal site have fallen and should be replaced. • Update records to include missing files (underground mining landowner notifications, documents pertaining to the SL -1 bond release). • Quarterly pond inspections are conducted by a P.E.; please ensure inspection reports are certified by a P.E. at least once annually if being used as the annual certification in accordance with Rule 4.05.9(14)(a). No compliance issues were noted and no enforcement actions were taken as a result of this inspection. in
