Trapper Mine <br />Records of Blasting <br />Page 3 <br />October 21, 2014 <br />the distance from the airblast monitoring unit to the blast will need to be included on the <br />blasting summary log. <br />Rule 4.08.5 states a record of each blast, including seismograph reports, shall be retained for at least 3 <br />years and shall be available for inspection by the Division and by the public on request. There appears to <br />be a delay between when the blast occurs to when the blasting summary log is completed with all the <br />required information. The Division understands there is a processing delay but believe a good practice <br />would be to have the blasting summary log completed with all of the required information within a week <br />of the blast. The Division appreciates the assistance Trapper's staff has provided in understanding their <br />blasting program. If you have any questions feel free to contact me at (303) 866 -3567, extension 8120. <br />Sincerely, <br />Jared Ebert <br />Environmental Protection Specialist <br />
