1. Destruction of damaged or deteriorating explosives or detonators; or <br />2. Disposal of misfires and/or undetonated explosives; or <br />3. Firing of charged holes as soon as practicable after cessation where electricity or stray current <br />conditions where electric detonators are used; or <br />4. Firing of chazged holes when weather conditions indicate the existence of a safety hazard is <br />eminent <br />Co]owyo gives warning and all-clear signals of different characters that are audible- within a range of one- <br />balfmile of the blast. Individuals within the permit area and individuals who reside or work within one-half <br />mile of the mining area will be notified of the meaning of the signals through appropriate written instructions. <br />Colowyo will periodically inform such individuals of the proposed blasting schedule and inform them of the <br />meaning of the signals. Colowyo will also maintain signs in accordance with Section 4.02. <br />Colowyo will regulate access into the area possibly subject to flyrock from blasting to protect the public and <br />livestock. Fences are in place to keep livestock out of the mining areas. The permit area will be identified by <br />signs on the access road restricting entry to authorized personnel. Signs will also be posted identifying the <br />area as a blasting area and describe the warning and all-clear signals. Immediate. access to the area of blasting <br />will be cleared and controlled by qualified mine personnel prior to any blast. <br />Colowyo will control air blast from its blasting operations within the permit area so it does not exceed the <br />values specified by the chart set forth in Rule 4.08.4(6). The satne design factors utilized to control the <br />seismic effects of blasting (i.e.: the use of numerous surface delays to "spread" the shots out over time, <br />particularly near residences) is also very effective in controlling airblast. Additionally, to keep airblast to a <br />minimum Colowyo uses various other methods to ensure airblasts are kept in compliance. <br />Colowyo will not conduct blasting within 1000 feet of any building used <br />Revision Date: 11 /21/03 <br />Revision No.: MR - 61 <br />4.08-3 <br />
