unoccupied dwellings or structures. Structures that are within 1,000 feet of blasting area (please <br />see Map 4.08-1) are: <br />Bortles, Ken <br />26491 Z Rd <br />P.O. Box 97 <br />Nucla, Colorado 81424 <br />Zunich, Charles & Katherine <br />26585 Z Rd, <br />P.O. Box 73 <br />Nucla, Colorado 81424 <br />Marie Patsy Tucker Family Revocable Trust <br />P.O. Box 826 <br />Nucla, Colorado 81424 <br />Structures that are within 500 feet of the blasting area (please see Map 4.08-1) include: <br />Garvey Bros Land & Cattle Company, LLC WFC- formerly Starks <br />26491 2600 Rd 26432 2650 Rd <br />P.O.

Box 571 <br />Nucla, Colorado 81424 Nucla, Colorado 81424 <br />The analysis of near dwelling blasting conducted at New Horizon 2 will allow safe blasting <br />within 500 feet of any structure at New Horizon North. <br />No blasting will occur within 500 feet of any disposal well, petroleum or gas -storage facility, <br />municipal water -storage facilities, fluid transmission pipelines, gas or oil collection lines, and <br />water and sewage lines. <br />Blasting will be conducted to prevent injury to persons, damage to public or private property <br />outside the permit area. Adverse impacts to underground mine workings will not occur as there <br />are not any underground mines (active or inactive) in the vicinity of the New Horizon North <br />Mine. Blasting will not impact or change the course, channel, or availability of surface or ground <br />waters outside the permit area. <br />Seismic recording instruments will be utilized to monitor ground vibrations from blasting. The <br />seismographs will measure and record peak particle velocity in three mutually perpendicular <br />directions (transverse, vertical & longitudinal). Seismographs will be checked after each blast to <br />ensure compliance with the peak particle velocity is less than 1 inch per second as set forth in <br />Rule 4.08.4(10). Seismographs will be placed at the closest non -company owned structures or <br />company owned structures that are leased or rented, to the actual blast site or at some point in <br />between a blast and the structure or dwelling. Seismograph records will be kept in accordance <br />Section 4.08.5. <br />Section 4.08 Page- 4 - December 2015 (TR -12) <br />
