January 2,2013 C-1996-084/Lorencito Canyon Mine LDS inspection,but Mr Steele was able to get machinery to the site and repair the culvert by Friday afternoon(see photos 5 and 6). Those pictures also show the slope above which was in poor condition and will need a concerted effort over an extended period to control erosion and establish vegetation. The first culvert on the road to Pond 8 was blocked and must be cleared(see photos 7 & 8). This was also noted as a problem in the October inspection report and it appears that the elevation of the culvert relative to that of the ditch is too low for it to be effective. It is not clear whether this culvert"belongs"to NECC or to Pioneer Oil and Gas;regardless,these two must co-operate to maintain roads,ditches and culverts and this structure is critical to the designed management of surface water at the site,if it does not function as intended,the Division must hold NECC responsible. The other culverts on the road to pond 8 were all clear. Pond 8 was dry, although a little water had pooled upstream.Both spillways were in good shape.Fill 8, as viewed from the pond,was mostly snow-covered and appeared to be in relatively good shape (see photos 9-14). The level area far above pond 5,which is the only disturbed area reporting to this pond,has been suggested previously as suitable for permitting as an SAE,which could then allow for reclamation of pond 5 (see photo 15). The western edge of this area has some drainage issues which will need to be resolved before re-permitting is feasible.A substantial gully had formed a few feet to the north of the natural drainage,which was also noted in the October inspection report(see photos 16-18). This gully must repaired. Some thought should also be given to a longer term solution to erosion in this area, since the current strategy of controlling flow with straw bales has not been effective. If the creation of an armored ditch is favored,this should be handled in conjunction with the permit renewal. Above Pond 6 straw bales and rock check dams have been effective at controlling sediment runoff,however the sparse vegetation in the drainage reporting to Pond 6 means that the quantity of sediment is large and these bales need to be replaced(see photos 19-22). Pond 6 appeared to be in good shape, although a significant gully has formed below the pond,outside the emergency spillway(see photos 23 &24).NECC should develop a plan to address. GENERAL MINE PLAN COMPLIANCE: The permit renewal for Lorencito Canyon is on-going. This process should resolve some of the outstanding inconsistencies with maps and clarify the identification of, and the parties responsible for,various roads and culverts. SIGNS AND MARKERS—Rule 4.02: As with other NECC properties,the mine ID sign must be updated to show the new address. The permit boundary sign below Pond 8 was in place (see photo 13). Since this was a partial inspection,other boundary markers were not checked.
