Hebert home. This monitor has been checked over years of operation. No tests have ever shown <br /> a particle velocity from blasting that has been above the design limit of 0.5 inches per second. <br /> There has never been a problem with damage from blasting at the home and none is expected in <br /> the future, although the Pit will move closer to the home. The particle velocities recorded at the <br /> home are very low and they will be continued to be monitored. Gary Horton is the Senior <br /> Environmental Coordinator at CC&V who conducts all blast monitoring and related work in and <br /> around the permit area. He has provided a letter report of the original blast design criteria,the <br /> pre-blast surveys, monitoring information and results. This report and related information is <br /> included in Attachment T-3. <br /> 23) Monitoring wells (4x) and road owned by Marlene Chapman <br /> The four monitoring wells owned by Marlene Chapman are located approximately 4,900 feet <br /> southwest of the toe of the toe of the Arequa Gulch VLF. The wells are immediately east of the <br /> Shelf Road and there are no existing or planned mine activities any closer than the Arequa Gulch <br /> VLF so there is no way that the wells could be affected by failure of the VLF. Since the VLF is <br /> lined and there is monitoring in place to ensure that the liner remains intact, it is extremely <br /> unlikely that a rupture could occur that would affect the wells. The measures to ensure that this <br /> will not happen are included in the Environmental Protection Plan of the approved Permit. <br /> 24) Road to excavation area owned by Shiloh Plain, Inc. <br /> There is a dirt two track road located approximately 2800 feet west of the Arequa Gulch VLF. <br /> The road is barely used and leads to the Perreten excavation area (Structure 25). There are no <br /> existing or planned mine facilities that will be closer than the 2800 feet distance to the VLF. For <br /> this reason, no further evaluation is needed. <br /> 25) Excavation area owned by William Perreten <br /> There is a minor surface disturbance of less than 0.1 acres that is located at the end of the Shiloh <br /> Plain road, which is approximately 2700 feet west of the Arequa Gulch VLF. There are no <br /> existing or planned mine facilities that will be closer than the 2700 feet distance to the VLF. For <br /> this reason, no further evaluation is needed. <br /> 26) CC&V Narrow Gauge railroad tracks on land owned by Rexanne <br /> Rowe <br /> The CC&V Narrow Gauge Railroad is a tourist railroad that runs from the old 1894 depot in the <br /> Town of Cripple Creek south to near the wye where the old Colorado Midland Terminal was <br /> located. The tracks continue to near the Squaw Gulch VLF. The tracks are mostly outside the <br /> 51 <br />
