• 4.08 USE OF EXPLOSIVES <br />4.08.1 General Requirements <br />Colowyo will comply with all applicable State and Federal laws in the use of explosives. <br />Colowyo will conduct all blasts that use more than five pounds of explosives or blasting <br />agent according to the schedule required by Section 4.08.3. <br />All surface blasting operations at the Colowyo operation will be conducted by experienced, <br />certified, trained and competent persons who understand the hazards involved. Persons <br />responsible for blasting operations at a blasting site shall be familiar with the blasting plan <br />and any site-specific performance standards. The blaster and at least one other person must <br />be present at the firing of a blast. Each person responsible for blasting operations will <br />possess a valid certification in accordance with the appropriate federal and state law. <br />Colowyo will not conduct blasting within 1000 feet of any building used as dwelling, school, <br />church, hospital, or nursing facility; and 500 feet of facilities, including but not limited to <br />petroleum or gas storage facilities, fluid transmission pipelines, gas or oil collection lines or <br />water and sewage lines. Distances to various structures of possible concern surrounding the <br />mining area are shown on the Blasting Analysis Map (Map 26). <br />By employing the design criteria to minimize air blast and ground vibration Colowyo will <br />• insure that flyrock, including blasting material traveling along the ground, will not be cast <br />from the blasting vicinity, more than half the distance to a nearby dwelling or other occupied <br />structure and in no case beyond the line of property owned or leased by the Company or <br />beyond the area of regulated access required under Subsection 4.08.4(5). The minimization <br />of flyrock is also important and routinely monitored in order to reduce damage to mining <br />equipment. <br />u <br />4.08-1 Revision Date: 9/20/02 <br />Revision No.: RN-04 <br />
