other solid wastes (including, but not limited to, tires, hoses, and plastic sheeting) would be <br />• properly disposed of in accordance with state and local regulations. <br />Transportation <br />The Operator is responsible for ensuring that radiation levels from hauling operations fall within <br />applicable DOT limits as specified in 49 CFR 173.427(a)(1). These requirements state that the <br />external dose rate may not exceed a radiation level of 1,000 mrem/hr at 3 meters from the <br />unshielded material. Based on the grade of the uranium ore from the Van 4 Mine, the exposure <br />rate would be less than 1 millirem per hour (mrem/hr) to recipients standing outside of the truck. <br />As a result, the requirements at 49 CFR 173.427(a)(1) are expected to be satisfied. <br />Requirements at 49 CFR 173.427(a)(5) and 173.441(a) state that under conditions normally <br />incident to transportation, the radiation level shall not exceed 200 mrem/hr at any point on the <br />external surface of the package and the transport index shall not exceed 10. These requirements <br />are also expected to be satisfied in all cases. The average reading in the occupied space of each <br />truck cab is not expected to exceed the DOT limit of 2 mrem/hr as specified in 49 CFR <br />173.441(b)(4). In addition, the Operator would perform (and document for the record) spot <br />gamma surveys on uranium ore shipments as appropriate in order to ensure that the regulatory <br />standards are satisfied. <br />The Operator's transportation policy specifies that ore trucks must be covered at all times, with <br />or without ore, except for loading and unloading, using a tarpaulin or other suitable mechanism. <br />With regard to accidents and other incidents involving the spillage of uranium ore, the policy <br />states that the transportation contractor is responsible for handling the accident and that the <br />contractor must have an Emergency Response Plan in case of emergency. <br />Recreation <br />Aside from surface facility areas, no public land access would be restricted by mining activities. <br />Signs would be posted advising the public of any mining activity and any road construction <br />activity. Cones and gates would be used when necessary to limit access or divert traffic at mine <br />surface facilities. <br />Air Quality <br />To control dust emissions, the Operator would cover haul truck beds with tarps for off-site <br />transportation of ore. <br />To control emissions from vent holes, watering of underground operations would take place to <br />reduce dust generation underground. <br />The Operator would spray water or chemical suppressants as needed on the storage piles to <br />reduce fugitive dust. Emissions from the topsoil storage piles would be controlled by vegetation <br />that has been or would be established on the piles. Dust emissions from storage piles must meet <br /> <br />3
