Pressure plate <br /> 9. Unsaturated hydraulic conductivity <br /> 10. Proctor compaction <br /> V. Infiltration Modeling needed,such as Heap leach Draindown Estimation,Tailings Impoundment <br /> Draindown Estimation,cap/cover materials,etc. <br /> VI. Waste Hock Management Plan <br /> I. Work plan history with geochemical and geotechnical summaries. <br /> 2. Operating/post reclamation management of the waste rock dumps(WRDs) <br /> 3. Describe mining sequence of rock types/volumes/final disposition(see section 111.2 above). <br /> 4. Describe how potentially acid generating(PAG)rock wilt be selectively mined,segregated and managed <br /> to preclude exposure to air and water.Need to address metals mobility/accumulation for both PAG and <br /> non-PAG materials(see section 1115.c). <br /> S. For each benign and PAG WRO facility,Include a text description for:toe elevation,crest elevation, <br /> ultimate height,reclaimed slope,plan dimensions,tonnage capacity and acres.Provide a summary <br /> table for volumes by facility far life-of-mine(LOM). <br /> 6. Supplement the text with plan and cross sectional drawings showing:plan views and related <br /> alluvial/cover stockpile locations,cross sectional views showing operational and post reclamation <br /> slopes,grades,toe and crest elevations,existing ground slope and cap thicknesses for tOM. <br /> 7. For pit backfill scenarios,Include the same text and supporting drawings previously described,describe <br /> any amendment requirements.Provide information on the total volume to be backfilled with rock type <br /> and its origin,final backfill elevation and rebound ground water elevation. <br /> 8. Tagirgs impoundments,heaps,ore stockpiles,topsoil stockpiles should include the same text and <br /> supporting drawings previously described. <br /> `7CL <br /> Page 16 of 36 <br />
