Used on surface to <br /> connect together and provide delay time between Nonelectric <br /> MS Detonators. (Detonator assemblies, nonelectric, 1.1 B, UN <br /> 0360 PG II or Detonator assemblies, nonelectric, 1.4B, UN <br /> 0361 PG II) <br /> ■ Detonating Cord - A flexible cord containing a center core of <br /> high explosives which may be used to initiate other high <br /> explosives. (Cord, Detonating, 1.1D, UN 0065, II EX <br /> 1992020035) <br /> o Any other products deemed necessary by the blasting sub-contractor <br /> Storage of Explosives <br /> At no time will explosives be stored onsite at Hitch Rack Ranch Quarry. Majority of <br /> blasting at Hitch Rack Ranch will be done using bulk explosives. All bulk explosive <br /> ingredients and explosive accessories will be brought to the site the day of the blast by <br /> the third party blasting contractor. Any unused quantities of bulk explosive ingredients <br /> and explosive accessories will be taken off site at the end of the blast by the same <br /> contractor that brought it to site. When bulk explosives are to be used, quantity of <br /> explosives on site is minimized. Bulk delivery equipment used by third party contractor <br /> carries bulk non explosive ingredients (Oxidizer and fuel) and mixes the non-explosive <br /> ingredients as they are loaded(pumped or augered) into the drill hole to make Blasting <br /> Agent. All bulk explosives are in placed in blastholes. Cast boosters and detonators are <br /> the only explosives handled on bench at site (max 120#total). There will be no unused <br /> bulk explosives to be transported off site. Where package explosives (Type E I.1D or <br /> 1.5D) may be required (e.g., for presplit or development work), these will be transported <br /> to site by US DOT/MSHA approved truck and explosives not used in daily operations <br /> will be returned to third parry blasting contractor's storage location. While on site, all <br /> explosives will be closely monitored and supervised by qualified personnel. <br /> Dates and Times of Blasting <br /> After a pattern is drilled the quarry manager will contact the third party blasting <br /> contractor with the number of holes, hole diameter, pattern dimensions, hole depths, and <br /> condition of the holes including the amount of water in each hole. From this information <br /> the volume of bulk explosives and blasting accessories will be determined. The quarry <br /> manager and the manager of the third party blasting contractor will schedule the blast for <br /> an appropriate date and time. The blast time will be adjusted on a case-by-case basis to <br /> minimize disruption to vehicle traffic on Little Turkey Creek Road. As discussed below, <br /> Little Turkey Creek Road is not within the "blast area" or"blast site" (as those terms are <br /> defined by MSHA) for any blast conducted at the Hitch Rack Ranch Quarry, but may at <br /> times fall within the scope of a safety corridor created as a measure of protection beyond <br /> strict regulatory requirements. Blasting will occur between the hours of 10:00 AM and <br /> 4:00 PM, with no more than three (3)blasts per week. The quarry manager will make <br /> 7 <br />
