June 23, 2014 C- 1996 - 084 /Lorencito Canyon Mine LDS <br />sediment were removed. Some erosion on the east side of the pond had been repaired and protected. The silt fence <br />on the emergency spillway had been repaired and reinforced with straw bales. The weir box had been cleaned out. <br />The primary spillway riser had been completely exposed showing all of the weep holes. The area disturbed and <br />reseeded last year (when the major erosion was repaired) was well vegetated. A small sump had been created at <br />the sharp right turn from the pond access road to the pond itself, with a rock check dam. The sump will treat water <br />from a relatively small area (just that which is not diverted through culvert C 19 or the XTO culvert below it) and <br />should be easier to clean of sediment than the pond. <br />Ponds 8 and 5 were dry. No recent work or disturbance had taken place. The shrubs on the embankment of <br />pond 5 were significant. <br />Pond 9A was dry. No problems were observed. The down drains were inspected and were in good shape <br />with no evidence of recent erosion. <br />Pond 7 was dry. A couple of significant shrubs were growing on the embankment. <br />Pond 6 was being cleaned of sediment at the time of the inspection. The check dams and bales running <br />beside the road leading to pond 6 were in need of cleaning out. In the case of the bales, if it is determined that they <br />are still necessary, many of them should probably be replaced this season. At the time of the inspection work had <br />not begun on the slope above pond 6, although the ditch above the slope had been prepared to allow access. The <br />low spot around the east side of the pond had not yet been touched. <br />Culverts were generally clear around the site and most ditches were in good shape, including a contour <br />ditch (D 19) which initially appeared from a high spot to be incised - on closer inspection the ditch really wasn't <br />incised very deeply and was already down to crumbly bedrock, with vegetation higher up. In contrast, the ditch <br />leading from the outlet of culvert C4 to the down drain on the east side of pond 7 (D 119) was badly eroded, <br />including a sharp drop of —6 ft at one point. The material appeared to be loose and ripe for further erosion. The <br />ditch should be repaired to prevent escalation of the problem. <br />GENERAL MINE PLAN COMPLIANCE: <br />TR18 - The proposed decision due date has been extended to August 29, 2014. The Division is awaiting a <br />response to the adequacy letter of May 29, 2013. <br />ROADS — Rule 4.03 <br />Construction 4.03.1(3)/4.03.2(3); Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance 4.03. 1(5) and <br />(6)14.03.2(5) and (6); Reclamation 4.03.1(7)14.03.2(7): <br />The roads were in good shape. The repeated passage of dump trucks carrying sediment from ponds 9 and <br />6 to the sediment drying area had loosened the surface of the roads, but not to the extent that any repair was <br />needed. <br />REVEGETATION — Rule 4.15 <br />Vegetative Cover; Timing: <br />The shrub plot was not exactly thriving, however there were transplants that were still alive - without <br />doing a survey it is hard to be more specific. NECC may wish to monitor the success of the transplants sooner <br />rather than later to gage the likelihood of meeting the revegetation success criteria. <br />TOPSOIL — Rule 4.06 <br />Number of Partial Inspection this Fiscal Year: 8 <br />Number of Complete Inspections this Fiscal Year: 4 <br />Page 3 of 15 <br />
