• <br />Transporting uranium ore to the Mill in accordance with Section 6 below. <br />• Unloading transported uranium ore at the Mill. <br />• Maintaining exclusive (sole) use of the transport vehicle for uranium ore shipment and <br />providing a closed conveyance trailer while shipping uranium ore to the Mill (see <br />Sections 2 and 6.1). <br />• Carrying and delivering to the Mill a copy of the shipping; papers which will accompany <br />the uranium ore shipment (see Section 5). <br />• Ensuring that the training requirements described in Section 3.1.1 are satisfied. <br />• Preparing and adhering to an Emergency Response Plan (see Section 7). <br />• Contacting DUSA personnel listed on the shipping documents and providing emergency <br />response and cleanup personnel should accidental spillage of uranium ore occur during <br />transport to the Mill (see Section 7). <br />• Requesting an unrestricted use release survey from Mill radiation safety personnel when <br />the transport vehicle is planned for uses other than umaium ore haulage (see Section <br />8.3.2). <br />1.3. DUSA Responsibilities <br />DUSA personnel will be responsible for: <br />Assisting in emergency response situations if accidental spillage of uranium ore during <br />transport has occurred (see Section 7). <br />Completing radiation surveys of the transport vehicles -prior to return to service for . <br />unrestricted use and shipment of commodities other than uranium ore (see Section 8). <br />Signing and retaining all shipping and survey records perhining to shipments of uranium <br />ore (see Sections 5 and 9). <br />2. Classification of Ore and Exclusive Use Shipments <br />The Colorado Plateau uranium ore that will be shipped from the Mine to the Mill is classified as <br />Class 7 Radioactive LSA-I "hazardous material" under 49 CFR .171.8. However, shipments of <br />32 tons or less per trailer will generally not constitute an A2 quantity of any Class 7 radioactive <br />material, within the meaning of 49 CFR 173.403, due to the relatively low specific activity of the <br />uranium ore. This means that the shipments will generally be exempt from most of the marking <br />and labeling requirements (see Section 2(e)). It is the responsibility of the Mine operator/owner <br />to ensure that ore shipments from the Mine are not A2 quantities of Class 7 radioactive material. <br />An A2 quantity means that the activity from Unat or from any of its daughters in any ore <br />shipment exceeds the activity level set out in the table in 49 CFR 173.435. <br />Although the Colorado Plateau uranium ore will generally not on average have a high enough <br />specific activity level to constitute a "hazardous substance" under 49 CFR 171.8, D' USA has <br />concluded that it is nevertheless prudent that shipping papers and an emergency response plan, <br />normally required only for shipments of hazardous substances under 49 CFR 177.200, 177.817 <br />and 172.600, be required for each load of uranium ore (see Sections 5 and 7 below). <br />0 <br />July 5, 2007 2 Rev 0
