BLAST MONITORING <br />In order to obtain much more accurate information regarding detailed <br />blasting plans and schedules for the area within 550 feet from the <br />Dorchester Fuel Storage Facilities, GEC made specific arrangements <br />to monitor the 4:30 p.m. inter-burden blast on Wednesday, January 28, <br />1981, with six (6) seismographs on the Dorchester property. <br />Based on the recommendations provided by GEC's Blasting Consultant, <br />VME-Nitro Consul Inc., GEC Minerals, Inc., intends to use "regression <br />analysis" to design the blasting plan and schedule. The maximum <br />weight of explosives to be detonated within any 8 Millisecond Period <br />is listed as follows: <br /> Maximum GEC Proposed' <br />Distance (Ft) ANFO LB to use (Lb) <br />200 25 17-25 <br />300 56 39 <br />400 100 70-90 <br />500 150 100-140 <br />*For conservative blasting GEC only uses portions of the maximum weight <br />of ANFO to be used for 8 MS delay. <br />
