July 18, 2012 C- 1994- 082/Yoast Mine SLB <br />4.05.6, Discharge Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2, Ground Water <br />Monitoring 4.05.13; Surface Water Monitoring 4.05.13; Drainage — Acid and Toxic Materials 4.05.8; <br />Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />Ponds 010, 011A, 012, 012A, 013, and 014 all held water. Only Ponds 010 and 012 were discharging. <br />Pond 012A had evidently discharged through the secondary spillway, at a flow depth of approximately 10 -12 ". <br />The trash rack on Pond 012A was covered in debris but still functional. It should be cleared as soon as possible. <br />ST -1 held water below the discharge elevation, the surge structure above the "Bear Bait" drainage (YPM -24) was <br />dry. <br />ROADS — Rule 4.0 ❑ Construction 4.03.1(3)/4.03.2(3) ❑ []Drainage 4.03.1(4)/4.0).2(4)[111 Surfacing and <br />Maintenance4.03.1(5) and (6)/4.03.2(5) and (6)❑ ❑Reclamation 4.03.1(7)/4.03.2(7): <br />Roads were in good condition overall, but there were a few areas where runoff had crossed the road and <br />caused washouts. On Road B /LU -3A, near the Neck Pit slide, runoff backed up behind one of the check dams and <br />crossed the road in a gully about 9" deep. This area and several areas along LU -3B that were washed out and will <br />need to be repaired. <br />REVEGETATION — Rule 4.15 ❑ ❑ Vegetative Cover; Timing: <br />The SP07 -2 shrub plot that was reworked last year was still fairly weedy (thistle and houndstongue) but <br />most of the shrubs were alive. The area around the newly constructed surge structures in the North Pit YPM -13 <br />drainage was weedy. These two areas should be sprayed this season. In general, the weed population in the <br />reclaimed areas was much less than last year. <br />DOCUMENTS RECEIVED Exhibits A -1, B -1, and C -1 for SL -4 application. <br />ENFORCEMENT ACTIONS /COMPLIANCE <br />No enforcement actions were initiated as a result of this inspection, nor are any pending. <br />PHOTOGRAPHS <br />Pond 010 <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 3 of 6 <br />Channel on south side of Topsoil Stockpile I <br />
