to the distance to the mine excavation and the slope stability analyses that have been performed <br /> by CNI for the Main Cresson Mine, this structure should never be affected by the mine activity. <br /> 21) Single story single family house and driveway owned by Carol <br /> Barron <br /> The home owned and occupied by Carol Barron is a single story wood frame house at the end of <br /> the northernmost street(6`h Street) in the Town of Victor. It is the closest occupied dwelling not <br /> owned by CC&V to the mine activity. The closest edge of the South Cresson Mine pit to the <br /> home will be approximately 830 feet when full excavation is done. Since the Elkton and Cresson <br /> Mine Road is closer to the Pit than the Barron home, the slope stability evaluation for the Pit is <br /> included in the discussion for Structure 6 - Elkton and Cresson Mine Road. <br /> Since the home is relatively close to the final Pit, a seismic monitor has been placed in the home <br /> and has been checked over years of operation. <br /> Gary Horton is a Senior Environmental Coordinator at CC&V who conducts all blast monitoring <br /> and related work in and around the permit area. He has provided a letter report of the original <br /> blast design criteria, the pre-blast surveys, monitoring information and results. This report and <br /> related information is included in Attachment T-3. <br /> These monitors record blast information 24 hours per day. All measurements at the monitors <br /> have been well below the design limit of 0.5 inches per second. The monitors are set to trigger at <br /> 0.05 inches per second, which is ten times lower than the design velocity. There has never been a <br /> problem with damage from blasting at the home and none is expected in the future, although the <br /> Pit will move closer to the home. The particle velocities recorded at the home are very low and <br /> they will be continued to be monitored. <br /> 22) Two story single family house and driveway owned by Matthew & <br /> Leana Hebert <br /> The home owned and occupied by Mathew and Leana Herbert is a single story wood frame <br /> house near the end of the northernmost street (61h Street) in the Town of Victor. It is the 2°d <br /> closest occupied dwelling not owned by CC&V to the mine activity. The closest edge of the <br /> South Cresson Mine pit to the home will be approximately 870 feet when full excavation is done. <br /> Since the Elkton and Cresson Mine Road is closer to the Pit than the Barron home, the slope <br /> stability evaluation for the Pit is included in the discussion for Structure 6 - Elkton and Cresson <br /> Mine Road. <br /> Since the home is relatively close to the final Pit, and also within 190 feet of the Barron home, <br /> the seismic monitor which has been placed in the Barron home is also used to evaluate the <br /> 50 <br />
