GENERAL NOTES ON MINING AMENDMENT AREA: <br />Mining of amendment connects with mining of land to the north of the amendment. General <br />mining direction to be north to south. Although overflow protection berms help protect the pit from <br />river overflows, it would be best to mine and backfill between mid - September and mid -April when <br />there is the least chance of river overflows occurring. Care must be exercised to not affect trees in <br />the 100' setback zone as those are major protection to keep the river in place. Backfill is best done <br />in more or less horizontal lifts, but avoid compacting backfill any more than is necessary. Pit <br />sideslopes can be steep to maximize recovery of rock. Pit should connect with pit to the north for <br />dewatering purposes. <br />GENERAL NOTES ON RECLAMATION: <br />Backfill to the original elevation. Do not compact backfill <br />any more than necessary; excessive compaction will limit the <br />success of revegetation. After completion of backfill, remove <br />Overflow Protection Berm by spreading over the top of the <br />backfill. For revegetation requirements, refer to the <br />Reclamation Plan (Exhibits E and F). <br />X <br />CD X 4602:9 <br />CD <br />x 4604:3 <br />4606/ a: m <br />X / N <br />4�( L� <br />o, <br />X46 4 ;I <br />6 :2 O <br />x, rn <br />ExistinglRipRap n X 4603. <br />- <br />- <br />- - -- <br />- - -- - - -- - - -- - - - - - -- <br />-------- - ---- - - - - -- <br />xsection A2 B oo -- <br />x46 l <br />03,0 <br />I� x <br />x4 � <br />I 4ti6 <br />I — I <br />W W W W <br />_ r <br />W W W W W W <br />J W W W W <br />W = W W W W <br />W W `V y6 qaW._ <br />• _ _ RR. r r <br />W W W W W W° NQ [D W F3BA* NQ <br />W W WALL vCFE[3),& ` <br />X y Otl1W` W^^yy��� nnW W_ W <br />W W W W W W X 6�J V 8W W <br />���I�IIIVJJJ VVVV� IIIJJJ <br />OVERFLOW PROTECTION BERM <br />(3 to 4 feet high - see plan for further description) <br />=se s:� Ae�r7 PERMIT BOUNDARY <br />(INCLUDES NO DISTURBANCE SETBACK ZONE) <br />MINING LIMIT <br />(NO CLOSER THAN 100' FROM RIVER BANK) <br />Setback from river is 100' <br />(protection berm may lapse <br />a few feet into setback, <br />otherwise no disturbance <br />in setback zone. Overburden <br />will not be stockpiled <br />in the setback zone.) <br />NOTES ON MINING "OLD BERM ": <br />Berm is composed of overburden and should be <br />used for backfill. Extraction of the berm will leave the <br />south side of berm unaffected. A low ridge will be left <br />along the south side of the Old Berm. The low ridge will <br />protect wetlands to the south from overflow from the <br />backfilled pit to the north and sedimentation that might <br />occur before full revegetation can be accomplished. <br />RECE'r <br />AUG 13 2004 <br />Permit #: M- 1986 -015 Confidential ?: N <br />Division of Mineral;, am; 6roiat,;. <br />Class: Recision Type /Seq.: AM -2 <br />From: Continental Mlaterials Corp To: DMG <br />Doc.
