If a berm is needed, the subsoil that was pushed into the eastern edge of Block 9 shall be limited to a 20' wide azea along the edge of the block. If no berm is needed, move the subsoil to the storage azea within 30 days of the approved contract for Block 2. 5. Timing -For Block 2 (and succeeding blocks), all stripping activities must be completed Qrior to the mining and crushing phase. In addition, all topsoil shall be stripped and stockpiled as per plan prior to any subsoil removal, and all subsoil shall be stripped as per plan prior to gravel mining. In order to ensure that the dirt-handling procedures identified above and in the forthcoming plan modification are understood by all parties involved, a joint field meeting will be required just prior to earthmoving activities. The United Companies production manager and crew foreman must be in attendance. We appreciate the effort that United has made to mitigate dust impacts from the operation. It is ~` - our understanding that the operation was temporarily shut down 3 days during the week of July 8's due to wind conditions. Please submit a copy of the work report for those days. The use of spray bars on the crusher and a water truck full-time on the site should be acceptable for dust control under normal conditions. Based on our observations and the recent residential complaint, we recommend that at the end of each work day, the water truck spray down all surfaces which have been disturbed that day. This would include the access trail leading to the east edge of the mine block, the surface of the exposed gravel or subsoil material, pit floor, and stockpile azeas.
