Individuals within the permit area and individuals who <br />reside or work within one-half mile of the mining area will be notified of the meaning of <br />the signals through appropriate written instructions. Colowyo will periodically inform such <br />individuals of the proposed blasting schedule and inform them of the meaning of the <br />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 <br />protect the public and livestock. Fences are in place to keep livestock out of the mining <br />areas. The permit area will be identified by signs on the access road restricting entry to <br />authorized personnel. Signs will also be posted identifying the area as a blasting area and <br />describe the warning and all-clear signals. Immediate access to the area of blasting will be <br />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 <br />not exceed the values specified by the chart set forth in Rule 4.08.4(6). The same design <br />factors utilized to control the seismic effects of blasting (i.e.: the use of numerous surface <br />delays to "spread" the shots out over time, particularly near residences) is also very <br />effective in controlling airblast. Additionally, to keep airblast to a minimum Colowyo uses <br />various other methods to ensure airblasts are kept in compliance. <br />Colowyo will not conduct blasting within 1000 feet of any building used <br /> <br />4.08-3 Revision Date: I I/21/03 <br />Revision No.: MR-61 <br />
