3.0 Loading Requirements <br /> The uranium ore is to be loaded into highway haul trucks using a front-end loader. Required dust <br /> and contamination control measures during loading include: <br /> 1) The loader operator and truck driver are to avoid inhalation of dust during loading <br /> operations. The ore is expected to be moist to wet when hauled from the mine to the ore pad. <br /> If the ore should dry out prior to loading, the stockpile will be sprayed with water to <br /> minimize the amount of dust generated during loading operations. Water sprays will be <br /> applied only to the extent necessary to moisten the ore and ore pad area. <br /> 2) Spillage onto the transport truck is to be avoided during loading operations. Any loose <br /> material that drops onto the cab, bumpers, running boards, or other exterior surfaces will be <br /> removed and placed back on the ore pad prior to leaving the site. The truck tailgate will be <br /> closed and a tarpaulin (or other suitable cover) will be placed over the entire load and <br /> adequately secured so that fine ore particles cannot be released to the environment during <br /> transport. <br /> 3) The tonnage to be shipped is not limited by Title 49, but rather, by the size of the trailer(s) <br /> and any weight restrictions imposed by local or state agencies on the roads to be traveled. <br /> Care shall be taken to not overload transport vehicles. <br /> 4) Shipment during muddy conditions is to be avoided to minimize off-site contamination and <br /> the potential for an accident. Muddy conditions could result in the tracking of ore material <br /> from the site onto adjacent public roads. A gravel tracking pad will be constructed at the exit <br /> to the ore pad if muddy conditions cannot be completely avoided. <br /> 4.0 Vehicle Survey and Shipping Papers <br /> Prior to leaving the site, the loaded truck must be surveyed for leakage and radiation. Shipping <br /> papers must be completely filled out and in the possession of the driver. Mine personnel will be <br /> required to maintain records of the inspections and radiation scans performed for each shipment. <br /> Specific survey and shipping requirements include: <br /> 1) The truck will be scanned to verify that it meets gamma exposure rates stipulated in Title 49. <br /> Radiation levels shall not exceed lrem/hr (10 millisievert/hr (mSv/hr)) at 3 meters from the <br /> load for an unshielded cargo (173.427), 200 mrem/hr (2 mSv/hr) on the conveyance or <br /> package surface, and 10 mrem/hr (0.1 mSv/hr) at 2 meters from the conveyance or package <br /> surface (173.441). The transport index (TI) is equal to the maximum gamma exposure rate in <br /> mrems/hr at 1 meter (3.3 feet) from the conveyance or package surface, rounded up to the <br /> nearest tenth. The TI must be below 10. The TI measurements will be performed at the front <br /> of the tractor, on both sides of the trailer, and at the tailgate. <br /> 14 <br />
