July 17, 2012 C -1996- 084 /Lorencito Canyon Mine JHB <br />NECC will need to monitor these repairs until then to assure that they do not become weedy or begin to erode <br />again. NECC will seed the gully repair areas with the approved seed mix. <br />NECC was advised to submit results of analytical sampling to the Division. The Division has not yet received <br />these results. Please forward this information to the DRMS. <br />Gullies documented as having been repaired include; 2 gullies on the south side of reclamation parcel S -3 <br />The gully on the east side of Pond No. 6 emergency spillway. <br />Several gullies on the SE facing slope of parcel W -1. <br />Several large gullies in parcel W -6. <br />Two gullies on the outslope of Fill 8. <br />One gully on the east side of Fill 8. <br />Several gullies on the lower slope of parcel N -2. <br />One Gully on the upper parcel of W -4 <br />Several gullies on the east slope of C -1 <br />Repairs look good at this stage and are in agreement with methods previously discussed. Two area previously <br />identified and potentially needing repair that NECC did not enact repairs were the north slope of parcel N -1 and <br />the south slope of parcel W -5. NECC evaluated the live perennial species establishing in the bottom of these <br />locations, and considered that these locations were self healing. The Division concurred but recommended <br />anchoring of limited wattles or other erosion protection material to break up the concentrated flows contributing to <br />additional growth of these features. Mr. Steele was in agreement with this treatment. <br />TOPSOIL — Rule 4.06 Removal 4.06.2, Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; <br />Redistribution 4.06.4: <br />A small topsoil pile remains on site in the W -5 parcel. NECC had begun to use some of this material in the repairs <br />but found the salvaged pond sediment material preferred due to a greater amount of fines and greater cohesion. <br />NECC needs to provide the results of the alternate growth material analytical tests for the Division's evaluation. <br />DOCUMENTS RECEIVED None <br />OTHER (SPECIFY) <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 4 of 9 <br />
