• All signals will be audible to all persons within one-half mile and each person who <br />works within the mine site area will be instructed of the meaning of the signals. <br />BME will post blasting warning signs at the entrance leading to the mine site and in <br />the immediate vicinity of the blasting area. <br />Access to the area subject to flyrock will be controlled by roadblocks and traffic <br />guards to prevent unauthorized personnel or livestock from entering the area. A <br />blasting representative will survey the area and announce the site safe following <br />each blast. <br />Flyrock, including blasting material, travelling along the ground will not be cast <br />beyond the permit area. <br />Blasting will be conducted to prevent injury to persons and damage to property <br />outside the boundary of the permit area. <br />There will be no change in the course, channel or availability of groundwater <br />outside the permit area due to the extremely long distance from the blasting area. <br />BME expects that the maximum weight of explosives that will be detonated at one <br />time in any 8-millisecond period will be less than 300 pounds. <br />There are no public buildings, disposal wells, petroleum or gas storage facilities, <br />municipal water storage facilities, fluid transmission pipelines, gas or oil collection <br />pipelines or water and sewage lines within 1,000 feet of the blasting site. <br />• Blasting Records - A record for each surtace blast will be retained and be available for inspection <br />for a period of three years following detonation. The records will contain the following: <br />1. Name of operator conducting blast. <br />2. Location, date and time of blast. <br />3. Name, signature and license number of blaster in charge. <br />4. Weather conditions. <br />5. Type of material blasted. <br />6. Number, holes, burden and spacing. <br />7. Diameter and depth of holes. <br />8. Types of explosives. <br />9. Weight of explosives. <br />10. Maximum weight of explosives detonated within any 8-millisecond period. <br />11. Maximum number of holes detonated within any 8-millisecond period. <br />12. Initiation system. <br />13. Type and length of stemming. <br />14. Mats or other protections used. <br />15.
