Kerr (Marr) Mine — 2011 Annual Hydrology Report <br />STATION 320 <br />EC -field <br />Date Flow Rate (cfs) Temp © pH —field (s. u.) (umhos /cm) <br />(field c ata sheets to be submitted ur der separate cover) <br />5.1 LOADOUT AREA SURFACE MAINTENANCE & ACTIVITIES <br />During November, 2011 as previously approved in the Permit Document and with the approval of the <br />Army Corp of Engineers' 404 Permit (Section 24), the former sedimentation pond, aka, Tipple Pond at <br />the Loadout site was drained and backfilled and the topsoil reapplied to the disturbed area. The early <br />winter conditions at that altitude did not allow seeding of the site at that time. Application of the <br />approved seed mix, mulching and crimping of the mulch is scheduled for the spring season (2012) <br />when ground conditions allow. <br />6.0 WELL INSPECTION <br />The wells associated with the Kerr Loadout Monitoring requirements were inspected for defects and /or <br />repair needs. No anomalous conditions were observed during the 2011 water year. Alluvial wells AP -1 <br />and AP -2, located at the Loadout, will continue to be monitored until monitoring requirements are <br />terminated or final bond release is achieved for that site. <br />
