The Division is reviewing your letter dated August 29, 2014 that you sent to <br />Marcia Talvitie regarding the Trapper Mine Blast Log Summary Form. We may have some additional questions <br />after we have finished our review. I called today to discuss of few of the items. <br />As you requested, I am e- mailing you to summarize what we discussed today. The first item we discuss was <br />issue #4 of your letter. I called to see if Trapper had modified the blast summary form to include a space to <br />record not only the distance but also the identification and direction from the nearest blast hole to the nearest <br />dwelling, school, church, or community or institutional building not located in the permit area or not owner nor <br />leased by Trapper Mine per Rule 4.08.5(4). Based on our discussion, Trapper is working on modifying the form. <br />We also briefly discussed compliance with Rule 4.08.5(l 1) which requires the maximum weight of explosives <br />used per 8- millisecond period be recorded on the blasting record form. <br />The last item we discussed was regarding airblast monitoring information required to be recorded. Per section <br />3.4.3, page 3 -31 of Trapper's permit, Trapper has committed to conducting airblast monitoring. Rule 4.08.5(17) <br />requires mines who conduct airblast monitoring to log the exact location of the instrument and the date, time and <br />its distance from the blast. Given Trapper's commitment to conduct airblast monitoring and the Rule requirement <br />this information should be recorded on the blast summary form. Please ensure this information is being <br />recorded. <br />Please let me know if you have further questions. <br />Thank you, <br />Jared <br />Jared r <br />https: / /mail.google.com /mail /u /0 / ?ui= 2 &ik= e29129fcb5& view =pt& search = inbox &th= l488f017b7d9abl b &siml= 1488f017b7d9abl b 1/2 <br />
