The schedule will be <br /> republished at least every 12 months. Before blasting in areas or at times not described in the <br /> published blasting schedule, a revised schedule will be promptly mailed to residents or owners of <br /> dwellings or persons who might regularly work within one-half mile of the area affected by <br /> blasting activities. Colowyo will conduct blasting at times identified in the blasting schedule <br /> (Figure 2.06-1), except in those unavoidable, hazardous situations where public or mine safety is <br /> involved. Unavoidable hazardous situations are seen to exist if safety requires the following: <br /> (1) Destruction of damaged or deteriorated explosives or detonators in a safe <br /> manner; <br /> (2) Disposal of misfires and/or undetonated explosives; <br /> (3) Firing of charged holes as soon as practical after cessation of static <br /> electricity or stray conditions where electric detonators are used; and <br /> (4) Firing of charged holes when weather or other conditions indicate the <br /> existence of a safety hazard is imminent. <br /> General Blasting Procedures <br /> Colowyo gives warning and all-clear signals of different character that are audible within a range <br /> of one-half mile from the point of the blast. Persons working within the permit area and each <br /> person who resides or regularly works within one-half mile from the blast area will be informed <br /> of the meaning of the signals through appropriate instructions.Access to the immediate area of the <br /> blasting site will be cleared and controlled by qualified mine personnel prior to any blast. Colowyo <br /> also maintains signs in accordance with 4.02.6. All areas subject to blasting are fenced for <br /> livestock. <br /> To protect the public, Colowyo will regulate access to any area possibly subject to flyrock from <br /> blasting within the permit area. The mine area will be identified by signs on all access roads <br /> restricting entry to unauthorized personnel. Signs identifying the area as a blasting area will <br /> describe the warning and all-clear signals. Four series of three short sirens and four series of three <br /> long sirens will be sounded before the blast. After checking the blast, the Blasting Foreman will <br /> report all clear to the barricade crews. <br /> Colowyo will use the explosive equation of 4.08.4 (10)(c)(i) to limit the pounds of explosive per <br /> 8ms period, similar to that shown on the Blasting Analysis Map (Map 26A).
