M-2005-071 +/ <br />ri <br />Dear Ms. Williams: <br />We are submitting a Motion for Clarification to the Board Order for the application <br />referred to above. The Order states that "ground vibration monitoring at the project site <br />shall continue for 30 days unless monitoring shows vibrations that could result in offsite <br />damages." From our discussions with Allen Sorenson of the DMG, it was our <br />understanding that monitoring would occur during a 30 day period at the beginning of <br />quarry ripping and/or rock crushing operations and that this monitoring would be <br />discontinued when enough data was collected to satisfy DMG staff that no potentially <br />problematic vibrations are being detected. Mr. Sorenson and Mr. Gordon Revey of <br />Revey Associates, Inc. agreed that the monitoring need only continue long enough for <br />adequate data to be collected and the additional expense of monitoiing continuously for <br />30 days would not be necessary unless the monitoring shows potentially problematic <br />vibrations. On behalf of Benson Brothers, we are requesting clarification of this <br />condition of the Order. <br />Thank you for your assistance. <br />Si~ncrerely, <br />/~~~G~ <br />Michael L.
