Potential for Exposure: The uranium ore transported to the mill ranges from 0.15 to 0.35 percent <br /> eUA. Based on EPA and NRC health-based standards, a cleanup action of material having this <br /> low of uranium content will not result in a worker becoming overexposed to radiation, even if <br /> the action extends over several work days. <br /> Required Personal Protection Equipment (PPE): Level "D" PPE consisting of work pants, <br /> sleeved work shirt, and sturdy work boots or shoes is required. Gloves, hard hats, safety glasses, <br /> dust masks, and steel-toed safety shoes/boots may be also required as needed. <br /> Cleanup Procedures: Because of its potential to cause a fire or contaminate nearby water courses, <br /> containment and cleanup of any fuel spills is normally the first priority. Many of the fire <br /> departments carry adsorbents and booms to contain and clean up these types of spills. Spilled ore <br /> materials, depending on the size of the spill, can be cleaned up with a loader, hand shovels, <br /> rakes, and shop brooms. If the spill is large, the ore should be transferred directly to another <br /> truck approved for uranium ore haulage. Smaller spills can be placed in barrels or other suitable <br /> containers. If it is windy, dust can be controlled with light water sprays; however, large volumes <br /> of water should not be used because this could result in runoff of water containing uranium and <br /> other contaminants. If the spill occurs near or within a stream or river, efforts should be made to <br /> limit the quantity of ore released to the water course. Because of its relatively low uranium <br /> content, however, no long-term environmental impacts would be expected if some of the <br /> material cannot be safely recovered. <br /> Cleanup Verification: After visible spilled ore material has been removed, a scintillometer or <br /> gamma meter should be used to identify any"hot spots" of residual radiation on ground surfaces. <br /> The hot spots can be marked using spray paint, chalk, or utility flags. After these hot spots are <br /> further cleaned, they should be rechecked with the instrument to verify that the area is at or near <br /> background radiation levels. This is normally readily achievable on hard surfaces such as <br /> concrete or asphalt. Some over-excavation of underlying soils may be necessary in gravel or <br /> grassy areas. If there is a concern regarding the cleanup levels achieved, sail samples can be <br /> taken of the contaminated area and a nearby uncontaminated area to establish background levels. <br /> Cleanup to a level of 5 pCi/g above background is normally considered adequate for protection <br /> of the environment. <br /> Disposal of Recovered Materials: Recovered materials that have been loaded for transport can be <br /> released by the assigned cleanup supervisor to be transported to the mill. Any materials <br /> contaminated with oil or fuel should be containerized and transported to a suitable holding area <br /> for later characterization and appropriate disposal. <br /> Decontamination of Equipment and Tools: The contract Emergency Response Team should have <br /> specific procedures in place for decontaminating equipment and tools for "free release" of these <br /> items. These procedures generally include cleaning protocols, collecting swipe samples for <br /> analysis, and scanning for radiation levels. <br /> Agency Notifications: Depending on the severity of the incident, one or more state and federal <br /> agencies may need to be notified. These notifications may include both verbal and written <br /> requirements and should be made by the transportation contractor with the assistance of the <br />
