~ Section 780.13 Continued. <br />• <br />Energy Fuels shall regulate access to an area possibly subject to <br />flyrock from blasting within the permit area to protect the public <br />and livestock, The general mine areas are identified by signs on <br />all access roads restricting entry to authorized personnel. Signs <br />identifying the area ae a blasting area describe the warning and <br />all clear signals. A modulated siren shall be sounded approxi- <br />mately 3 minutes before the blast. A single tone from the siren <br />will signal the all clear. Each specific blasting area will be <br />identified as such and all charged holes are guarded against un- <br />authorized personnel. Access to the immediate area of a blasting <br />site is cleared and controlled by qualified mine personnel prior to <br />a blast. <br />Energy Fuels shall use the explosive equation of paragraph (1)(1) <br />in 30 CFR 816.65 to limit the number of blast holes per delay such <br />• that the peak particle velocity limit of 1 inch per second is not <br />exceeded. If deviation from the number of holes per delay occur <br />(as shown in Blasting Pattern Alteration (Coal) (Map 39), and <br />Blasting Pattern Alteration (Overburden), (Map 40)) or upon request <br />from the regulatory authority, a seismograph will be utilized to <br />assure compliance. <br />A record of all coal and overburden blasts in the format as shown <br />in Figure 28, Blasting Record, shall be used at Energy Fuels. <br />Seismographic records will not be used due to the option Energy <br />Fuels has chosen to use the explosive equation in paragraph (1)(1) <br />of Section 816.65 and shown in Table 86, Case 1 - Blasting Parameters - <br />Overburden; Table 87, Case 2 - Blasting Parameters - Overburden; and <br />Table 88, Case 3 - Blasting Parameters - Overburden. <br />Energy Fuels will conduct blasting at times announced in the <br />blasting schedule, except in those unavoidable hazardous situations <br />• previously approved by the regulatory authority in the permit <br />application. <br />780-52 <br />
