If ground vibration or Air blast limits are exceeded, the operator will immediately report the event with causes and corrective actions to the Department. Use of explosives at the blast site that produced the excessive reading shall cease until corrective actions approved by the Department are taken. However,blasting may occur in other approved areas within the permitted boundary. Authorization to blast at the blast site may be granted at the time of the verbal reporting of the high ground vibration or high air blast reading if the circumstances justify verbal approval. Failure to report will constitute a permit violation. H. The operator shall take all reasonable precautions to ensure that flyrock is not thrown beyond areas where the access is temporarily or permanently guarded by the operator. Failure to take corrective measures to prevent flyrock and repeated instances of flyrock shall be considered a violation of the Mining Permit. I. Should flyrock occur beyond the permitted and guarded areas, the operator shall immediately report the incident to the Department. Further use of explosives on the mine site shall be suspended until the following actions have been taken: i. A thorough investigation as to the cause(s)of the incident shall be conducted. ii.

L. Traffic on SR 1117 (Galestown Road)shall be stopped at a safe distance from the quarry site during blasting activities. M. Unless it is impractical from a standpoint of safety, all shots shall be completely mucked prior to the detonation of adjacent blasts to ensure that the actual burden conditions can be determined for explosive loading conditions. N. Vulcan Construction Materials,LP's blasting contractor shall perform laser transit profiles of face conditions prior to shot design. This will ensure precise overburden dimension data can be utilized for determining explosive distribution in the blast design to minimize flyrock potential. O. Formal meetings involving Vulcan Construction Materials,LP, its blasting contractor,and blasting investigation consultant personnel shall be held on a regular basis to review blasting operations at this quarry operation. Videotape of blast events, seismograph data, shot design, and hole loading parameters shall be reviewed to ensure that blasting operations remain consistent and controlled. Page 10 10.
