February 18, 2015 C- 2010- 089/New Horizon North Mine BFB to the current design. The bottom and sides of the ditch are designed to be composed of soil but there may be some rock fragments from the rock ledge in the soil. The construction of pond 002 north ditch did not go beyond the stream buffer zone signs of Meehan Draw (photo 7). The stream buffer zones signs were still in place along Nygren Draw. These signs are less than 100 feet from the draw. WFC needs to apply for a stream buffer zone variance for this area or demonstrate that Nygren draw has less than a 1 square mile drainage area and does not warrant stream buffer zone protection as outlined in Rule 4.05.18. Water was being pumped to pond NHN -001 from the main pit. Pond NHN -001 contained some water but was not discharging. The discharge and outlet structures were free and clear of obstructions (photo 8). SIGNS AND MARKERS — Rule 4.02: Permit boundary signs were in place by the pond 001 discharge /flume structure and along the access road to the NH1 pond. TOPSOIL — Rule 4.06 Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution 4.06.4: Topsoil was salvaged for the construction of the Pond NHN -002 north ditch. The topsoil through this area varied in depth from 1 to 7 feet thick (photo 9). In areas where the topsoil was deep, a large vertical wall of topsoil remained that was susceptible to erosion. To protect the topsoil from erosion, WFC backfilled some bench 1 material from the ditch construction up against the vertical wall of topsoil (photo 10 & 11). The topsoil is undisturbed and is naturally consolidated and therefore will not mix with the ditch construction material.
