The explosives bunkers located in Elk Creek were checked. They were locked and found to be in compliance. Revegetation The drill road and pads in C Gulch were seeded by the end of August. Germination is very good over most of the area. The coconut and straw matting used to cover a majority of the reclaimed area is working very well to control erosion and to enhance the seed establishment. It was noted that where the matting was not used along a narrow strip on the outside of the disturbance, seed germination was poor. A copy of the seed tag was provided. OMI is seeding the species approved in the permitted seed mix. The rate of planting was higher than approved, but Mr. Milner said the rodents were eating quite a bit of seed and he wanted to be sure to get a good stand. He hopes the matting will help reduce the amount of seed that the rodents get! Heavy grazing is apparent at the reclaimed Bear Creek facilities. Several patches of thistle were observed in this area and should be sprayed this fall. Development Waste OMI is no longer depositing waste on the East Yard Pile. It has been compacted and is ready for topsoil placement. OMI is planning to use salvaged topsoil from the Elk Creek mine facilities development to cover the pile. If construction does not start soon, an alternate plan may be necessary. Waste is now being placed in the West Valley fill. In the first lift, OMI placed a layer of geotextile every four feet. The first lift is complete and OMI is currently placing waste in the 2"d phase of the 2nd lift. Waste is being placed in 6 inch lifts, rolled and compacted as the pile is constructed. Results from the compaction testing shows that nearly 100% compaction is being achieved. The first bench has been covered with at least four feet of material and it will be seeded this fall. Waste from the temporary waste pile in the East Yard is being trucked to the West Valley fill. The temporary pile is nearly depleted.
