SEDI!`1ENTATION PONDS <br />STRUCTURAL I~]SPECTIO:I PROGRAM <br />PURPOSE: To conduct structural inspection of sedimentation pond <br />dams for various hazardous conditions. This is as required by 30 CFR <br />817.46(b). <br />[4E'PHOD OF INSPECTION: <br />1. visually check for deformation in individual steel bin wall <br />members. This would constitute hoisting and buckling. <br />2. Visually check for deformation of bins in general. This <br />would constitute leaning of dam or uneven appearance. <br />3. Visually check for water leaks through or around the dam. <br />This might indicate piping out of dam material. The visual check <br />will go sufficiently downstream to observe leakage. <br />4. Check for erosion around the spillway aprons or around the <br />dam that might undermine the dam. <br />5. Dam movements will be monitored using surveying stations and <br />techniques. <br /> <br />I • <br />S,=JIMENTA j ford I <br />~'D ti:f7 <br />I i,l <br />t <br /> <br />-, ,:. <br />-~ • . . <br />- ' --~'- 2ETEN T IOtJ DA;ti1 <br />-=t~LAN - N'iO,~.1(TOf?I,VG LAYoI.IT <br />P~i;t~ia U=J~lT <br />STF: (t Dl~l <br /> <br />a~) watL <br />~_ <br />L>Vc'~ <br />~i'cjAt(.,' i/~OtaIT02 <br />~~~ <br />j`,'oT Tb ~L. <br /> <br />
