Name Fire System Schematic Drawing INTRODUCTION The purpose of this Emergency Response Plan this Plan is to reduce the risk to our employees and to the community from potential health safety and environmental emergencies that could arise at the Denison Mines USA Corp DUSA White Mesa Uranium Mill the Mill This plan includes the following evaluation of the potential risks for accidents including fire explosions gas releases chemical spills and floods including tailings dam failure that could occur at the Mill specific emergency programs for each potential event administrative response actions and emergency response contacts both internal and external The Mill operates under the jurisdiction of the following regulatory agencies Utah State Department of Environmental Quality Division of Radiation Control Mine Safety and Health Administration Environmental Protection Agency Utah State Department of Environmental Quality Division of Air Quality and Utah State Division of Natural Resources Bureau of Dam Safety This Plan follows the standard format and content for emergency plans for fuel cycle and materials facilities set out in U.S Nuclear Regulatory Commission NRC Regulatory Guide 3.67 January 1992 Reg Guide 3.67 to the extent applicable to the Mill Section of Reg Guide 3.67 states that in its emergency response plan and in coordination meetings with offsite authorities the licensee should convey the concept that fuel cycle and materials facilities do not present the same degree of hazard by orders of magnitude as are presented by nuclear power plants Thus the classification scheme for these facilities is different Reg Guide 3.67 also refers to NRCs NUREG-l 140 Regulatory Analysis on Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees S.A McGuire January 1988 for description of past incidents involving radioactive materials NUREG-1140 analyzed potential accidents for 15 types of fuel cycle and other radioactive material licensees including uranium mills for their potential for offsite releases of radioactive materials NUREG-1140 concludes that for most of these licensees for example uranium mills the degree of hazard is small and that the low potential offsite doses the small areas where actions would be warranted the small number of people involved and the fact that the local police and fire departments would be doing essentially the same things they normally do are all factors that tend to make simple plan adequate NUREG-1 140 concludes that an appropriate plan would identify accidents for which protective actions should be taken by people offsite list the licensees responsibilities for each type of accident including notification of local authorities fire and police generally and give sample messages for local authorities E-1 including protective action recommendations This approach more closely follows the approach used for research reactors than for power reactors As result this Plan incorporates the most appropriate responses for the Mill in accordance with the requirements of Reg Guide 3.67 and the conclusions set out in NUREG-1 140 MILL OVERVIEW Master files containing Material Safety Data Sheets MSDSs for all materials in use at the Mill are maintained at the Safety Office Mill Maintenance Office Mill Laboratory and Mill Central Control Room Copies are also on file at the Blanding Clinic Doctors Offices Blanding Fire House and Office of the San Juan County Emergency Medical Coordinator PLAN OBJECTIVES The primary objectives of this plan are To save lives prevent injuries prevent panic and minimize property/environmental damage to the lowest possible level To evacuate and account for all people in the area including visitors truck drivers contractors etc To provide assembly areas that are as safe as possible and which can be reached without traveling through hazardous area Assembly areas will be properly manned to deal with sick or injured persons and provisions will be made to evacuate those persons to proper shelter and To make adequately trained personnel available to cope with rescue and recovery operations as directed by the Incident Commander Li E-2 FACILITY DESCRIPTION 1.1 Description of Licensed Activity The Mill is located approximately miles south of Blanding Utah The Mill processes conventional uranium or uranium/vanadium ores to

Lake City at the University of Utah Medical Center approximately hours drive by highway or in Denver Colorado approximately hours drive by highway There are no facilities close to the Mill site that could present potential protective action problems All schools arenas stadiums prisons nursing homes and hospitals are located in Blanding approximately miles north of the Mill site E-12 There are no sites of potential emergency significance such as liquefied petroleum gas LPG terminals chemical plants pipelines electrical transformers and underground cables in the vicinity of the Mill other than Mill site facilities described in detail in Section 1.2 above E-13 TYPES OF ACCIDENTS 2.1 Description of Postulated Accidents The following is description of each type of radioactive materials and other accident that could potentially occur at the Mill site that could require an emergency response 2.1.1 Unloading Storage of Ammonia release of anhydrous ammonia could occur through tank failure overfilling and failures of piping loading hoses hose couplings and emergency relief valves No radiological impacts are foreseen from release of anhydrous aiæmonia However in the event of an ammonia tank spill the material would be expected to evaporate quickly Release of the entire contents of one or both of the onsite ammonia tanks during short period of time could result in significant release to the environment the atmosphere of hazardous material that could require response by an offsite organization to protect persons offsite Such release is addressed in the Mills Risk Management Plan required under Section 12r of the Clean Air Act copy of which plan is attached hereto as Appendix The Risk Management Plan contemplates worst case scenario of the release of the entire 140000 pound contents of one of the anhydrous ammonia tanks over 10 minute period which could result in dangerous cloud of anhydrous ammonia that could extend 12 miles from the point of origin at the Mill An alternate scenario of release of 500 pounds of ammonia over one minute period could result in dangerous cloud of anhydrous ammonia that extends 0.8 miles from the point of origin Therefore an uncontrolled release of ammonia that could result in the release of 100 or more pounds of ammonia is classified as Site Area Emergency Any other uncontrolled release of ammonia other than minor release is classified as an Alert minor release of ammonia is classified as an On-Site Emergency See Section below for discussion of the significance of these classifications minor release of ammonia would be any release that is expected to be of small amount less than gallons 35 pounds that is not expected to be uncontrolled Minor releases of ammonia are not subject to the notification requirements of this Plan however they are subject to the procedures for response to an ammonia release outlined in Appendix The procedures for response to an ammonia release are outlined in Appendix An uncontrolled release of 100 pounds 20 gallons or more of anhydrous ammonia would also require that notice be given to the Community Emergency Coordinator for the local Emergency Planning Committee under the Emergency Response and Community Right to Know Act see Section 10 below The procedures for giving such notifications are also set out in Appendix to this Plan 2.1.2 Ammonia Explosion in Building An ammonia-air explosive mixture could be formed inside the Mill and SX buildings if line E-14 ruptured Existing controls include emergency powered vent fans operator presence at all times for surveillance and one-inch piping that minimizes potential release amounts Radiological impacts from the explosion would be minimal and most likely contained within the restricted area unless the explosion resulted in fire see Sections 2.1.6 and 2.1.7 below for the emergency response procedures to follow in the event of fire An ammonia explosion would be classified as Site Area Emergency if it involved the uncontrolled release of greater than lOOlbs of anhydrous ammonia and as an Alert if it involved an uncontrolled release of 35 pounds gallons to 100 pounds 20 gallons of anhydrous ammonia Releases of less than gallons are classified as On-Site Emergencies see Section for significance of this classification Any contamination would be recycled or disposed of as appropriate The procedure for response to an ammonia explosion are set out in Appendix 2.1.3 Unloading/Storage of Propane/Propane Fire or Explosion release of propane could occur through tank failure overfilling and failures of piping loading hoses hose couplings and emergency relief valves Daily inspections of the propane tank for leaks and integrity are conducted to minimize potential hazards associated with propane leaks No radiological impacts are predicted for release of propane unless the release is associated with fire Inhalation of propane is also less hazard than inhalation of ammonia and would not be expected to be significant threat to the public although it could pose hazards to workers in the immediate vicinity of the release Vapors can cause dizziness or asphyxiation without warning However there is significant risk of fire or explosion in the event that the release was uncontrolled and the propane was ignited Such release is addressed in the Mills Risk Management Plan required under Section 12r of the Clean Air Act copy of which plan is attached hereto as Appendix The Risk Management Plan contemplates worst case scenario of the release of 110000 pounds of propane resulting in vapor cloud explosion extending 0.40 miles from the point of origin An alternate scenario of release of 500 pounds of propane could result in vapor cloud explosion extending 0.01 miles from the point of origin The propane tank is located approximately 0.5 miles from Highway 191 and the nearest Mill property boundary so propane explosion is unlikely to have direct offsite impacts However as matter of caution notice is provided to offsite authorities An uncontrolled release of propane that could result in the possibility of an explosion is classified as an Alert minor release of propane see below is classified as an On-Site Emergency See Section below for discussion of the significance of these classifications minor release of propane would be any release that is expected to be of small amount and that is not expected to be uncontrolled or pose risk of explosion Minor releases of propane are E-15 not subject to the notification requirements of this plan however they are subject to the procedures set out in Appendix The procedures for response to propane release are outlined as Appendix 2.1.4 Leach Tank Failure The rubber lined leach tanks contain the nearly boiling ore/sulfuric acid slurry Tank failure due to corrosion and break-out is possibility Procedures and practices are in place and functioning to minimize this possibility Failure due to loss of structural integrity is also possible The tanks are evaluated as required to determine structural stability and the potential need for replacement Radiological impacts are minimal from an occurrence of this type Any release of material would be contained in the leach area or would flow to the lined catchment basin Roberts Pond west of the Mill for containment as designed Accidents of this type are classified as On-Site Emergencies See Section for the significance of this classification The procedures for response to leach tank failure are outlined in Appendix and in the Mills Spill Prevention Control and Countermeasures Plan For Chemicals and Petroleum Products the Spill Response Plan copy of which is attached as Appendix to this Plan 2.1.5 Sulfuric Acid Storage Tank Failure The Mills sulfuric acid storage tanks consist of one large above ground tank that can hold up to 1600000 gallons and two smaller tanks with capacities of 269160 gallons each Tank failure due to corrosion and break out is possible Failure due to loss of structural integrity as well as failures of piping loading hoses hose couplings and emergency relief valves sulfuric acid tank spill would flow via an above ground path to tailings Cell or to Roberts Pond There would be no radiological impacts associated with an accident of this type Nor would there be any significant hazards to the environment from off gases from any such release However there would be potential hazards to workers in the close vicinity from contact with sulfuric acid or inhalation of sulfuric acid vapors and release to the surface soils The large tank is equipped with high level audible alarm which sounds prior to tank overflows The two smaller tanks are also equipped with high level audible alarms Accidents of this type are classified as On-Site Emergencies because they will not lead to significant release to the environment of radioactive or other hazardous material See Section below for the significance of this classification The procedures for response to sulfuric acid tank failure are outlined in Appendix and in the E-16 Mills Spill Response Plan 2.1.6 SX Fire The possibility of maj or fire in the solvent extraction building is remote as very strict safety precautions are adhered to This part of the process is kept isolated and in separate buildings due to the large quantities of kerosene present These facilities are equipped with an independent fire detection and protection system In the event of fire in the solvent extraction building the fire suppression system delivers foam to the affected area The foam is designed to spray for 25 minutes followed by water at 100 psig and up to 2000 gpm In spite of the safety precautions major fire in the solvent extraction building could occur NRC staff concluded in NUREG-1140 that fire in the solvent extraction circuit is the accident of greatest significance for emergency preparedness for uranium mill from the point of view of potential radiological impacts offsite However NRC staff concluded that the calculated dose from this type of accident is small 0.1 rem or less because of the very low specific activity of the uranium and the low volatility of the uranium compounds which causes low release fraction NRC staff noted that these low release fractions are the reason why no offsite ground contamination was ever detected due to the historic fires that have occurred at other uranium mills In the 980s two solvent extraction fires occurred at other uranium Mills Neither fire resulted in appreciable release of uranium to the unrestricted environment and essentially complete recovery of the uranium was obtained As result NRC staff concluded in NUREG-1140 that no credible accident would justify emergency protective actions because radiation doses to the public offsite from an accident would be below the EPAs protective action guides Also the quantity of uranium inhaled is below the quantity where chemical toxicity effects are observed Thus neither radiation doses nor chemical toxicity from licensed materials is concern with respect to the need for prompt protective actions If major fire were to occur the radiological environmental effects would be confined within few hundred feet of the buildings Recovery of uranium that would be scattered by the burning solvent would be accomplished Uranium-contaminated soil would be processed in the Mill circuit or disposed of in the Mills tailings cells as appropriate The Mill would be required by existing regulations to take certain actions Among these the Mill would be required by 10 CFR 20.20 1b to conduct surveys offsite if appropriate to determine whether the NRCs limits on radioactivity in effluents to unrestricted areas in 10 CFR 20.106 were exceeded major fire would also require immediate notification of the Executive Secretary by telephone 10 CFR 20.403 Consequently the impact from such an event at the Mill would be limited to cleanup of contaminated material replacement of destroyed Mill components and short duration release of combustion products to the atmosphere major SX fire is classified as an Alert See Section for the significance of this classification El The procedures for response to an SX fire are outlined in Appendix 2.1.7 Other Fire fire could start anywhere in or around Mill facilities as result of number of causes such as lightning strikes electrical malfunction human error etc However at the Mill there is an increased risk of fire and of severe onsite or offsite consequences in the following areas due to the nature of the chemicals stored or used at those areas SX Building see Section 2.1.6 above Propane Tanks see Section 2.1.3 above and Lab or Lab Storage Area Fires could start in these areas due to equipment malfunction or hunian error and the intensity and consequences of the fire could be severe although direct radiological hazard from any such fires would be expected to be relatively low see Section 2.1.6 fof discussion of the radiological impacts of an SX fire which is the type of accident considered to have the highest risk of radiological impacts at uranium mill To the extent that facilities are damaged as result of any such fire there could be secondary radiological hazards such as fire damage in the yellowcake product drying packaging and storage areas that would have to be evaluated As discussed in Section 2.1.6 above an uncontrolled fire in the SX building is classified as an Alert All other uncontrolled fires in Mill buildings are classified as On-Site Emergencies See Section for discussion of the significance of these classifications Should fire other than an SX fire occur the procedure outlined in Appendix for reporting and responding to fires will be followed the procedure to be followed for an SX fire is outlined in Appendix 2.1.8 Tornado Although this is highly unlikely tornado could occur at the Mill severe tornado could cause buildings and other strnctures to collapse chemical or gas releases major fires as well as general panic The environmental impacts from tornado could be the transport of tailings solids and liquids ores or product from the Mill area into the environment This dispersed material would contaln some uranium radium and thorium An increase in background radiation could result and if sufficient quantities are detected and isolated they would be cleaned up However NRC staff have concluded in NUREG-l 140 that while tornadoes could release large amount of radioactive material they spread the material so greatly that resulting doses are very small As result tornadoes are not discussed further in NUREG-l 140 and are not considered to be significant radiological risk at uranium mills However to the extent that tornado has caused or is likely to result in an ammonia leak or propane release an SX building fire or breach of the Mills tailings cells it would be classified as Site Area Emergency or Alert depending on which one of these other accidents resulted from the tornado All other tornadoes would be classified as On-Site Emergencies See Section E-1 below for the significance of these classifications In the event of major tornado the procedures outlined in Appendix cii will be followed 2.1.9 Major Earthquake Although this is highly unlikely an earthquake could occur at the Mill severe earthquake could cause buildings and other structures to collapse chemical and/or gas releases major fires as well as general panic NRC staff concluded in NUREG-l140 that earthquakes were not identified as leading to significant releases of radionuclides unless they were followed by fire To the extent that an earthquake has caused or is likely to result in an ammonia leak or propane release an SX building fire or breach of the Mills tailings cells it would be classified as Site Area Emergency or Alert depending on which one of these accidents resulted from the earthquake All other major earthquakes would be classified as On-Site Emergencies See Section for the significance of these classifications In the event of major earthquake the procedures outlined in Appendix will be followed 2.1.10 Tailings Accidents 2.1.10 Flood Water BreachinR of Retention System In general flood water breaching of tailings embankments presents one of the greatest dangers for the sudden release of tailings solids and impounded water The tailings cells are designed with sufficient freeboard at least three feet to withstand back-to-back 100-year storm events or 40%of the probable maximum flood PMF followed by the 100-year storm event The flood design is equivalent to 15 inches of rainfall In addition the tailings dikes were designed in accordance with NRC regulations and allow sufficient margin of safety even in the event of an earthquake The possibility of floods in Westwater Creek Corral Creek or Cottonwood Wash causing damage to the tailings retention facility is extremely remote This is due to the approximately 200 foot elevation difference between the streambeds of the creeks and the toe of the tailings dikes Flood water breaching tailings embankment is classified as an On-Site Emergency because it is unlikely that any releases to the environment will leave the Mill property and in the event that any contamination were to leave the property it is unlikely that the release is expected to require response by an offsite response organization to protect persons offsite See Section below for the significance of this classification In the event of Flood Water Breach of the tailings retention system to procedures in Appendix will be followed E-19 2.1.10.2 Structural Failure of Tailings Dikes All tailings dikes have been designed with an ample margin of safety as per NRC regulations This has included design calculations showing dike stability even when the dike is saturated with moisture during seismic event the most severe failure mode In addition the tailings discharge system is checked at least once per shift during operation or once per day during Mill standby NRC staff concluded in NUREG-1 140 that tailings pond failures also release large quantity of material However NRC staff concluded that rapid emergency respoiise is not needed to avoid doses exceeding protection action guides because dose rates at spill site are very low NRC staff concluded that an appropriate response is to monitor drinking water especially for radium- 226 to be sure that drinking water standards are met Gamma ray monitoring of the ground is also appropriate to determine where the tailings have been deposited However NRC staff concluded that ground contamination presents little immediate hazard to the public because the gamma dose rates are low Gamma dose rates in contact with tailings should be less than 0.1 mR/hr clean-up of the spilled tailings would be expected buy this could be done effectively without pre-existing emergency preparedness Although the discharge from dike failure would soon cross the restricted area boundary the flow path is over three miles in length before leaving the Mill property In the event of dam failure large operating equipment will be mobilized to construct temporary earthen dikes or berms downgradient to the failed dike In addition the State of Utah Division of Radiation Control Executive Secretary the Executive Secretary MSHA and State of Utah Department of Natural Resources Division of Dam Safety will be notified The contamination from such an event would be cleaned up and returned to the tailings area tailings dam failure is classified as an On-Site Emergency because it is unlikely that any releases to the environment will leave the Mill property and in the event that any contamination were to leave the property it is unlikely that the release is expected to require response by an offsite response organization to protect persons offsite See Section for the significance of this classification In the event of tailings dam failure the procedures outlined in Appendix will be followed 2.1.103 Seismic Damage to Transport System In the event of seismic rupture of tailings slurry pipeline the released slurry will be contained in the tailings cells regardless of the quantity released The tailings retention system pipe is in the same drainage basin as the retention system Any tailings slurry released by pipe rupture no matter what the cause would flow downhill where it would be impounded inside tailings cell If break occurred the pumping system would be shut off personnel removed from the immediate area and the Executive Secretary notified The break would be repaired and the affected area cleaned up in the safest and most expeditious manner The advice and direction of the Executive Secretary would be sought and heeded throughout the episode E-20 seismic rupture in the tailings slurry pipeline would be classified as an On-Site Emergency See Section for the significance of this classification In the event of rupture in the tailings slurry pipeline the procedures outlined in Appendix will be followed 2.1.11 Terrorist/Bomb Threat In the event that any person should receive threat of bomb the procedure set out in Appendix should be followed Because of the unknown nature of the risk terrorist/bomb threat is classified as an Alert See Section for the significance of this classification In the event of terrorist/bomb threat the procedures in Apperfix will be followed 2.1.12 Chemical or Reagent Spills Tanks which are likely to overflow are equipped with high level alarms to reduce the possibility of spillage due to tank overflow and dikes and/or curbs are constructed around process and storage tanks excluding the water tank to confine the material in the event of tank spill However as an operating facility it is possible for spills of chemicals or reagents to occur from time to time Unless such spill qualifies as an ammonia release see Section 2.1.1 above propane release see Section 2.1.3 above or sulfuric acid release see Section 2.1.5 above the spill will be considered minor spill and will be addressed and cleaned up in accordance with the Mills Spill Response Plan It is unlikely that any such minor spills will impact the environment if cleaned up in accordance with the Mills Spill Response Plan The entire Mill facility is graded such that mn-off will drain into the Mills tailings cells copy of the Mills Spill Response Plan is included as Appendix to this Plan Any such minor spills are classified as Non-Subject Incidents See Section for the significance of this classification 2.1.13 Transportation Accident on the Mill Property Involving Spill of Yellowcake In the event of transportation-related accident on the Mill property involving spill of yellowcake immediate containment of the product will be achieved by covering the spill area with plastic sheeting or equivalent material to prevent wind and water erosion If sheeting is not available and depending on where the spill occurs soil from the surrounding area may be used Perimeter ditching will be used to contain the spill if it should occur in an area where runoff could result from precipitation E-21 All human and vehicular traffic through the spill area will be restricted The area would be cordoned off if possible All persons not participating in the accident response will be restricted to 50 feet from the accident site Local law enforcement officers will be notified and may be asked to assist in controlling traffic and keeping unauthorized persons out of the spill area Covered containers and removal equipment i.e large plastic sheeting radioactive signs ropes hoses shovels vacuums axes stakes heavy equipment front-end loaders graders etc will be available to clean up the yellowcake Radioactive Material Spill Kit is available and under the control of the Radiation Department If conditions warrant water will be applied to the spilled yellowcake in fine spray to assist in dust abatement Gloves protective clothing and any personal clothing contaminated during cleanup operations will be encased in plastic bags and kept in the plant area for decontamination or disposal Any fire at the site will be controlled by local experienced fire fighting personnel wearing appropriate respiratory protective equipment Response team members will have thorough knowledge in basic first aid and of the physical hazards in inhalation ingestion or absorption of radionuclides Team members will adequately protect themselves As per R3 13-15 requirements the Executive Secretary will be notified promptly of any accident of this type Any minor spills are classified as Non-Subject Incidents See Section for the significance of this classification 2.1.14 Offsite Transportation Accidents 2.1.14.1 Concentrate Shipments Concentrates will be shipped in sealed 55-gallon drums built to withstand normal handling and minor accidents Each drum will contain approximately 900 pounds of yellowcake maximum of 45 drums will be shipped in each closed van The drums will be sealed and marked Radioactive LSA low specific activity and the trucks will be properly marked Because most of the radioactive daughter products of uranium are removed in the extraction process and radioactive buildup of daughter products is slow yellowcake has very low level of radioactivity and is therefore classified by the Department of Transportation as low specific activity material The environmental impact of transportation accident involving release of the product would be minimal Yellowcake having high density even in severe accident in which multiple drums are breached would not easily disperse More than likely the drums and any released material would remain within the damaged vehicle or in an area of close proximity of the accident site Driver or carrier instructions are given to each driver of each transport leaving the plant site with load of yellowcake These instructions will consist of an explanation of the product preliminary precautions at the accident site whom to notify and what to do in case of fire copy of these instructions is included in the Mills Transportation Accidents Plan copy of E-22 which is attached as Appendix to this Plan Mill personnel would respond if requested for the initial spill response to handle any yellowcake transport accident procedure for this likelihood is included in the Mills Transportation Accidents Plan DUSA may contract with carrier or firm properly trained to handle any yellowcake transport accident Offsite accidents involving the transportation of product concentrats are classified as Non- Subject Incidents See Section for the significance of this classification In the event of an offsite accident involving spill of yellowcake the procedures outlined in the Mills Transportation Accidents Plan attached as Appendix hereto will be followed 2.1 .14.2 Ore or Alternate Feed Material Shipments Ore is shipped in 20 to 25 ton shipments in highway trailers tSat are covered by taau1ins The truck trailers are labeled Radioactive LSA Because the ore is typically in the form of large particles and is typically wet 2%to 5%moisture the potential for significant release from an accident involving an ore shipment truck is quite small Alternate feed materials can be transported to the Mill in number of conveyances Most typically alternate feed materials are either shipped in bulk in intermodal containers either with or without secondary containment such as supersac or in steel drums possibly in plastic overpacs in the back of van trailer Bulk shipments in intermodal containers are labeled Radioactive LSA For bulk materials the potential release from an accident is similar to potential releases from an accident involving conventional ores but this may vary depending on the feed material and the manner of conveyance The potential release from alternate feed materials that are transported in drums will vary depending on the particular alternate feed material and in some cases could be equal to or exceed the risks associated with transportation of yellowcake In the event of an accident the transportation company will respond to clean up any spilled material and ensure that the area is clean Mill personnel will support the transportation contractor in cleaning up the affected area and radiological scanning of the impacted area Offsite accidents involving the transportation of ores and alternate feed materials are classified as Non-Subject Incidents See Section below for the significance of this classification However the State of Utah Division of Radiation Control 801-536-4250 during normal business hours or after hours to the UDEQ Duty Officer at 801-536-4123 should be notified as soon as possible but no later than 24 hours after the incident 2.1 .14.3 Reagent Shipments Reagents are shipped in properly marked trailers and the driver are trained in hazardous materials transportation and accident procedures In the event of an accident all of the reagent suppliers E-23 transportation contractors are required to have emergency response contractors to respond to an accident and potential spill Many of the reagents that are used at the Mill are shipped on daily basis to other industrial facilities throughout the United States The potential for an accident is minimized due to quick response of the transportation contractors emergency response team and the training of many of the countrys emergency response services Offsite accidents involving the transportation of reagents are classified as Non-Subject Incidents See Section below for the significance of this classification However the State of Utah Division of Radiation Control 801-536-4250 during normal business hours or after hours to the UDEQ Duty Officer at 801-536-4123 should be notified as soon as possible but no later than 24 hours after the incident 2.2 Detection of Accidents Mill personnel perform number of daily and weekly inspections of the Mill facilities These are The Mills Shift Foremen conduct inspections of all facility areas each operating shift The Mills RSO or designee performs daily inspection of all facility areas Mill personnel perform daily weekly monthly and quarterly inspection of the Mills tailings cells and The Mills RSO or designee perform weekly inspections of all areas of the Mill These inspections particularly the shift and daily inspections provide means for Mill personnel to detect and alert the Mills operating staff of any abnormal operating condition or of any other danger to safe operations These inspections along with the observations of operating personnel in any impacted area are the primary means of detecting the accident and alerting the operating staff for chemical or gas leaks any fires in areas that do not have fire detection equipment or any impairment to the tailings cells For areas of the Mill with fire detection equipment such as the SX Building the office building and the Maintenance/Warehouse Building in addition to the foregoing inspections the fire detection equipment would be expected to also provide an early warning of fire Tanks which are likely to overflow are equipped with high level alarms to reduce the possibility of spillage due to tank overflow For terrorist or bomb threats the threat itself would provide the means of detection of the incident Where no threats are given suspicious activity would be observed during the shift and daily inspections In addition the Mill employs surveillance cameras in limited number of areas which are intended to allow Mill personnel to monitor product storage areas and certain access points to the facility The required responses to any detected accidents are set out in Section 2.1 above and in Appendices through for the various types of accidents E-24 CLASSIFICATION AND NOTIFICATION OF ACCIDENTS In this Emergency Response Plan accidents have been classified into four categories as described below It should be noted that Reg Guide 3.67 concludes that fuel cycle and material facilities such as the Mill do not present the same degree of hazard by orders of magnitude as are presented by nuclear power plants Thus the classification scheme for the Mill which has four classes of accidents Alerts Site Area Emergencies On-Site Emergencies and Non-Subject Incidents is different from the classification scheme for other nucleaf facilities which have two classes of accidents Site Area Emergencies and Alerts Reg Guide 3.67 provides that NRC intends that licensees be allowed to have single emergency plan that can apply to all licensee needs and regulatory requirements To this end it should be understood that licensee may wish to include in the emerency plan some incidents that do not fall within the jurisdiction of the NRC For example the licensee may wish to include industrial accidents or fires unrelated to the licensee s/Work with nuclear materials The licensee may include such incidents in the emergency plan As result this Plan includes On-Site Emergencies most of which do not involve risks of offsite releases of radiation and are therefore not specifically required by Reg Guide 3.67 to be included in an emergency response plan for the Mill and Non-Subject Incidents which are incidents that are addressed by other plans such as the Mills Spill Response Plan and Transportation Accidents Plan and that either involve incidents that could occur on site but that would not involve risks of offsite releases of radionuclides or that involve offsite accidents and for these reasons are not required by Reg Guide 3.67 to be included in this Plan These On-Site Emergencies and Non-Subject Incidents are included in this Plan in order to compile all potential emergencies into one Plan Although in some cases this merely involves referencing the type of accident or incident and then referring the reader to another plan the purpose is to allow Mill personnel to have reference source that will allow them to be able to respond quickly to each type of incident 3.1 Classification System At the Mill there are four classes of accidents Alerts Site Area Emergencies On-Site Emergencies and Non-Subject Incidents described as follows Alert An Alert is defined as an incident that has led or could lead to release to the environment of radioactive or other hazardous material but the release is not expected to require response by an offsite response organization to protect persons offsite An Alert reflects mobilization of the Mills emergency response organization either in standby mode that will activate some portions of the Mills organization or full mobilization but does not indicate an expectation of offsite consequences However an Alert may require offsite response organizations to respond to onsite condition such as fire E-25 The following potential accidents are classified as Alerts An uncontrolled release of 35 pounds gallons or more but less than 100 pounds 20 gallons of anhydrous ammonia see Section 2.1.1 An ammonia explosion that involves release of 35 pounds gallons or more but less than 100 pounds 20 gallons of anhydrous ammonia see Section 2.1.2 An uncontrolled release of propane that could result in an explosion see Section 2.1.3 major fire in the SX building see Section 2.1.6 and terrorist/bomb threat see Section 2.1.11 Site Area Emergency Site Area Emergency is defined as an incident that has led or could lead to significant release to the environment of radioactive or other hazardous materialand that could require response by an offsite organization to protect persons offsite Site Area Emergency reflects full mobilization of the Mills emergency response organization and may result in requests for offsite organizations to respond to the site Although it is unlikely that Site Area Emergency requiring offsite actions will occur at fuel cycle or materials facility such as the Mill the Mill must nevertheless be able to recognize potential offsite hazards and make the required notifications in such manner that offsite response organizations can take appropriate actions such as sheltering or evacuating persons in the affected area Accordingly the following potential accidents have been classified as Site Area Emergencies because they could require response by an offsite organization to protect persons offsite An uncontrolled release of 100 pounds 20 gallons or more of anhydrous ammonia see Section 2.1.1 and An ammonia explosion that involves release of 100 pounds 20 gallons or more of anhydrous ammonia see Section 2.1.2 On-Site Emergency An On-Site Emergency is defined as an incident that is of nature that has not led or could not lead to significant release to the environment of radioactive or other hazardous material and hence does not qualify as an Alert or Site Area Emergency but that nevertheless could pose significant and unusual safety hazards to workers at the site and is therefore subject to the procedures under this Plan The following potential accidents are or could be classified as On-Site Emergencies minor release less than 35 pounds gallons of anhydrous ammonia that is not uncontrolled see Section 2.1.1 E-26 An ammonia explosion in building unless this results in fire in the SX building an uncontrolled release of 35 pounds gallons or more of anhydrous ammonia or an uncontrolled release of propane that could result in an explosion in which case the classifications applicable to those other incidents would apply see Section 2.1.2 minor release of propane that is not uncontrolled and could not lead to an explosion see Section 2.1.3 leach tank failure see Section 2.1.4 sulfuric acid storage tank failure see Section 2.1.5 fire other than major fire in the SX building see Section 1.7 tornado unless this results in fire in the SX building an uncontrolled release of anhydrous ammonia or propane in which case the classifications applicable to those other incidents would apply see Section 2.1.8 major earthquake unless this results in fire in the SX building an uncontrolled release of anhydrous ammonia or propane in which case the classifications applicable to those other incidents would apply see Section 2.1.9 and Tailings Accidents flood water breaching of the tailings retention system see Section 2.1.10.1 Structural failure of tailings dike see Section 2.1.10.2 and Seismic damage to the tailings transportation system see Section 2.1.10.3 Non-Subject Incidents Non-Subject Incident is defined as an incident that involves an accident of specific nature that is covered under different plan and is not subject to this Plan but is listed in this Plan for informational purposes only The following potential incidents are or could be classified as Non-Subject Incidents chemical or reagent spill other than release of anhydrous ammonia or propane or sulfuric acid leak or spill These types of spills are covered by the Mills Spill Response Plan see Section 2.1.12 transportation accident on the Mill property involving spill of yellowcake These accidents are covered by the Mills Spill Response Plan see Section 2.1.13 and An offsite transportation accident Concentrate shipments These types of accidents are covered by the Mills Transportation Accidents Plan see Section 2.1.14.1 Ore or alternate feed material shipments see Section 2.1.14.2 and Reagent Shipments see Section 2.1.14.3 3.2 Notification and Coordination 3.2.1 Alert The purpose of declaring an Alert is to ensure that emergency personnel are alerted and at their emergency duty stations to mitigate the consequences of the accident that the emergency is E-27 properly assessed that offsite officials are notified and that steps can be taken to escalate the response quickly if necessary An Alert like Site Area Emergency differs from an On-Site Emergency or Non-Subject Incident in that offsite response authorities are notified as well as the State of Utah Division of Radiation Control This is because there is potential for offsite consequences The actions to be taken in the event of an Alert vary somewhat depenjing on the incident The actions to be taken for each incident described in Section 2.1 above that is classified as an Alert are set out in the various subsections in Section 2.1 and corresponding Appendices through to this Plan that relate to the specific incidents The actions set out in the Appendices describe to the extent appropriate for each incident how and by whom the following actions will be taken with respect to each specific incident Decision to declare an Alert this has been predetermine9 1y incident Activation of onsite emergency response organization Prompt notification of offsite response authorities that an Alert has been declared normally within 15 minutes of declaring an Alert Notification to the State of Utah Division of Radiation Control immediately after notification of offsite authorities and in any event within one hour of the declaration of an Alert Decision to initiate any onsite protective actions Decision to escalate to Site Area Emergency if appropriate Decision to request support from offsite organizations and Decision to terminate the emergency or enter recovery mode 3.2.2 Site Area Emergency The purpose of declaring Site Area Emergency is to ensure that offsite officials are informed of potential or actual offsite consequences that offsite officials are provided with recommended actions to protect persons offsite and that the Mills response organization is augmented by additional personnel and equipment Site Area Emergency like an Alert differs from an On-Site Emergency or Non-Subject Incident in that offsite response authorities are notified as well as the State of Utah Division of Radiation Control This is because there is potential for offsite consequences Unlike an Alert Site Area Emergency assumes that offsite emergency response assistance will be required The Mill has identified only two incidents that should be classified as Site Area Emergencies an uncontrolled release of 100 pounds 20 gallons or more of anhydrous ammonia and an ammonia explosion that involves the release of 100 pounds 20 gallons or more of anhydrous ammonia The actions to be taken in the event of such Site Area Emergencies are set out in subsection 2.1.1 above and in Appendices and to this Plan and describe to the extent appropriate how and by whom the following actions will be taken E-28 Decision to declare Site Area Emergency this has been predetermined by incident Activation of onsite emergency response organization Prompt notification of offsite response authorities that Site Area Emergency has been declared including recommendation for offsite protective actions normally within 15 minutes of declaring Site Area Emergency Notification to the State of Utah Division of Radiation Control immediately after notification of offsite authorities not later than one hour after the Mill has declared Site Area Emergency Decision on what onsite protective actions to initiate Decision on what offsite protective actions to recommend Decision to request support from offsite organizations and Decision to terminate the emergency or enter recovery mode 3.3 Information to be Communicated Mill personnel will do their best to provide clear concise information to offsite response organizations The communication should avoid technical terms and jargon and should be stated to prevent an under-or over-evaluation of the seriousness of the incident The procedures set out in the Section 2.1 and Appendices through describe the key types of information that will be communicated with respect to facility status releases of radioactive or other hazardous materials and recommendations for protective actions to be implemented by offsite response organizations where applicable Such Appendices also contain the preplanned protective action recommendations the Mill will make to each appropriate offsite organization for each incident that is classified as an Alert or Site Area Emergency including the size of the area where the actions are to be taken The Appendices also contain standard reporting checklist to facilitate timely notifications Mill personnel meet annually with the various offsite emergency response providers to ensure that This Plan contains the most practical and efficient protective actions for each postulated accident and that such providers understand and agree with the recommended courses of action and the notifications set out in this Plan are appropriate and the contact information is current E-29 RESPONSIBILITIES 4.1 Normal Facility Organization The Mill Manager is ultimately responsible for the Mill site The Mill Manager reports to the Executive Vice President US Operations of DUSA The Executive Vice President US

activity listed below During normal working hours while the Mill is in full operation all bf the individuals or their alternates should be available on site to fulfill their emergency assignments During evening or night shifts or during other times when the Mill is not in full operation not all of the individuals listed below will be on site However there will always be Shift Foreman on site Blanding is small town and most of the individuals listed below live within short distance of the Mill In the event of an emergency during non-working period afternoon or night shift during period of limited Mill operations or other situation wbere there is reduced staff at the Mill the Shift Forman or his supervisor if on site will initiate procedures to effect any necessary evacuations of the site and will contact the required personnel from the list of assignments below to assemble the team required in order to fill all of the necessary assignments Two of the first persons contacted will be the Mill Manager and the RSO who will ensure that the remalnder of the team is assembled in order to carry out the emergency procedures set out in this Plan for the emergency Facility System Operations The Mill Superintendent or in his absence Mill Foreman or the Mill Manager is responsible for all operational activities on the property In this capacity the Mill Superintendent Mill Foreman or Mill Manager can shut down any affected areas within the process and render aid to the other departments The Maintenance Superintendent or in his absence the Maintenance Foreman or the Mill Manager is responsible for all mechanical and instrumentation on the site and has the ability to gather resources during any declared emergency Shift Foremen are in charge until the foregoing personnel arrive and are responsible for all of the foregoing functions until relieved by one or more of the foregoing individuals Fire Control As Fire Chief the RSO has the responsibility to maintain trained fire crews and operable equipment mobilize and direct the fire crews and equipment in fire emergency or one containing the threat of fire and to assist in evacuation and rescue or recovery operations The RSO/Fire Chief makes sure that the team or crew has been established equipped and properly trained every six months The RSO/Fire Chief works with the Safety Department and the Safety Coordinator under 30 CFR 56.4330 Firefighting evacuation and rescue procedures E-33 In the absence of the RSO the Mill Safety Coordinator will assume these duties If the Safety Coordinator is not present those responsibilities fall to the next senior member of the Safety Department Scheduled time off at the Mill is worked around the RSO and Safety Coordinators time off Both individuals will not be given time off work at the same time thereby ensuring supervised coverage in the event of an emergency During an emergency situation the Safety Coordinator will also be present and receive direction from the RSOJFire Chief as to how to proceed If the RSO is present during the emergency the Safety Coordinator will act as the Assistant Fire Chief to free up the RSOs time to deal with radiation decontamination or other issues that may arise If the RSO is not present the Safety Coordinator will be the acting Fire Chief and the radiation designee will act as the Assistant Fire Chief but will only deal with radiation related issues Personnel Evacuation and Accountability The Malntenance Supervisor will direct all personnel in evacuatiOn and in activities to cope with the emergency including isolation of utilities and providing technical advice as needed The Maintenance Supervisor will be assisted by the Mill Safety Coordinator The Laboratory Supervisor has the responsibility to direct and account for all office personnel including DUSA personnel and office visitors in evacuation and in activities to cope with the emergency In case of mill tour the Supervisor accompanying the tour will be responsible for evacuation of visitors The Scale house person on shift will be responsible to account for ore truck drivers and reagent truck drivers The Mills Emergency Evacuation and Shut-Down Procedure is outlined in Appendix to this Plan Search and Rescue Operations The RSO will direct rescue operations and provide the necessary emergency medical personnel and facilities to cope with the emergency First Aid First aid will initially be the responsibility of the Safety Coordinator or Safety Technician If the need for first ald is minimal there may not be need to require offsite assistance However if there are any significant injuries or there is risk of any significant injuries the Safety Coordinator or Safety Technician will have the responsibility of contacting offsite medical and ambulance services for assistance E-34 Communications The Incident Commander will stop routine radio usage upon learning of an emergency and set up the base station in safe location for directing activities Radio usage will be limited to the emergency The Incident Commander has the responsibility to contact all outside services Radiological Survey and Assessment Onsite and Offsite On-site and offsite radiological surveys and assessments will be performed by one or more Radiation Technicians under the direction of the RSO The RSO may assist in performing any such surveys The surveys and assessments that will be required will depend on the incident Tn most cases radiological contamination resulting from the Mill would be expected to be limited and restricted to the Mill site In some cases however radiological contamination could be dispersed offsite The RSO will determine what surveys and assessments are reuired in order to determine to what extent if any radiological contamination has or could be dispersed offsite as result of the incident and determine what surveys are necessary in the circumstances to assess any onsite or offsite radiological contamination that may have resulted from the incident In the absence of the RSO the Lead Radiation Technician will make these determinations The Mill has established an emergency call sheet that will be used in the event of an emergency to alert all members of the department whether on-site and on-duty or not When an emergency occurs the RSO is notified first If the RSO is not available the Lead Radiation Technician is notified The on-shift Radiation Technicians notify the off-shift Radiation Technicians All Radiation Technicians are required to report to the site to assist in the emergency unless advised otherwise by the RSO This ensures that there will be adequate Radiation Safety Staff available for any emergency that may arise Personnel Decontamination Personnel decontamination will be performed by Mill Radiation Technicians under the direction of the RSO or in the absence of the RSO under the direction of the Lead Radiation Technician as needed Facility Decontamination Facility decontamination will be performed by Mill operations personnel maintenance personnel and/or utility crew personnel under the direction of the Mill Manager Mill Superintendent or Maintenance Superintendent to decontamination standards set by the RSO and monitored by Radiation Safety Staff E-35 Facility Security and Access Control The Mill Superintendent or in his absence Mill Foreman has the responsibility of directing outside emergency personnel and has the responsibility for plant security and will report directly to the Incident Commander Request Support from Offsite Agencies During an emergency the Incident Commander and/or the RSOIFire Chief will coordinate that the crew or team has the available members needed to respond to the emergency After the team or crew has responded and is in the process of handling the situation the Incident Commander and/or RSOIFire Chief will then coordinate with the Radiation/Safety Departments to maintain scene safety Scene safety includes but is not limited to crowd control outside emergency assistance requests and any decontamination Post-Event Assessment post-event assessment of facility conditions for future operations will be performed by the Mill Manager Mill Superintendent and/or Maintenance Superintendent post-event assessment of facilities for occupational safety will be performed by the Safety Coordinator post-event assessment of any on-site or offsite radiological contamination resulting from the incident will be performed by the Radiation Safety Staff under the direction of the RSO Record keeping The RSO will coordinate all record keeping relating to the incident and will be responsible for the preparation of an incident report Media Contact The Incident Commander President and Chief Operating Officer or Executive Vice President US Operations of DUSA shall be the sole media contact in the event of an emergency at the Mill 4.3 Local Offsite Assistance to Facility Under Letter of Agreement with the San Juan County Emergency Management Office DUSA will be assisted in the event of an emergency with all needed equipment and services at the disposal of San Juan County Local agencies have

Li The Mill has provided all of the foregoing facilities and agencies with Material Safety Data Sheets MSDSs for any potential incident at the Mill These are updated periodically by the Mill Also each facility has an understanding with DUSA that DUSA will perform all radiological assessments and decontaminate any area or equipment that has been contaminated during emergency activities Annual visits with each agency or facility are conducted to update and refresh the various departments about potential emergencies that may be encountered These visits are documented and housed in the Safety Office at the Mill E-37 Given that Mill personnel will be in attendance at any emergency situation there is no need to make any provisions to suspend security or safeguard measures for site access during an emergency in order to accommodate any of the agencies referred to above 4.4 Coordination with Participating Government Agencies Below are listed the principal State agency and other government local

Management and Fire Control and City of Blanding Fire Department to review items of mutual interest including relevant changes in this Plan During those meetings Mill personnel discuss the Plan notification procedures and overall response coordination as necessary E-38 EMERGENCY RESPONSE MEASURES Reg Guide 3.67 suggests that specific response measures should be identified for each class of emergency and related to action levels or criteria that specify when the measures are to be effected However rather than describe specific responses applicable to classes of emergencies this Plan describes the specific response measures for each type of accident Since the number of different types of accidents that have been postulated for the Mill is relatively small it was concluded that this more direct approach is most appropriate for facility such as the Mill There is no need to describe the specific actions and responses for each class of emergency when the actual specific response measures can be described more directly for each accident Section 2.1 and Appendices through set out the specific response measures for each postulated accident 5.1 Activation of Emergency Response Organization Activation of the Emergency Response Organization for each type of accident is set out in Section 2.1 and the applicable Appendix through contact list is maintained through the Mill Safety Department All supervisors and key personnel onsite have copy of this contact list The individuals listed are available at all times Blanding is small town and most of the individuals listed live within short distance of the Mill In the event of an emergency during non-working period afternoon or night shift or during period of limited Mill operations or other situation where there is reduced staff at the Mill the Shift Forman or his supervisor if on site will initiate procedures In addition the Radiation Safety Department has established an emergency call sheet that will require notification throughout the department When an emergency occurs the RSOIFire Chief is notified and then the Shift Radiation Technicians notify the off shift Radiation Technicians The shift Radiation Technicians will maintain scene security until directed by the RSO to do otherwise When the off duty Radiation Technicians arrive they will report immediately to the RSO and receive their instructions 5.2 Assessment Actions For each type of emergency the actions to be taken to determine the extent of the problem and to decide what corrective actions may be required are set out in Section 2.1 and the applicable Appendix through Where appropriate Section 2.1 and the applicable Appendix describe the types and methods of onsite and offsite sampling and monitoring that will be done in case of release of radioactive or other hazardous material To the extent not specifically addressed in Section 2.1 or in Appendices through Mill personnel will use procedures contained in existing Mill Standard Operating Procedures E-39 5.3 Mitigating Actions The means and equipment provided for mitigating the consequences of each type of accident are specified in Section 2.1 and Appendices through To the extent applicable these include the mitigation of consequences to workers onsite as well as to the public offsite as well as the criteria that will be used to decide whether single process or the entire facility will be shut down The Mills Emergency Evacuation and Shut Down Procedure is set out in Appendix 5.4 Protective Actions The nature of onsite and offsite protective actions the criteria for implementing those actions the areas involved and the procedures for notification to affected persons are described in Section 2.1 and Appendices through for each type of accident Ii order to prevent or minimize exposure to radiation radioactive materials and other haztrdous materials the procedures specified in Section 2.1 and those Appendices provide for timely relocation of onsite persons timely recommendation of offsite actions effective use of protective equipment and supplies and use of appropriate contamination control measures appropriate for each specified type of accident To the extent that any actions and equipment are described generally in Section 2.1 and those Appendices Mill personnel will take actions and use equipment in accordance with Mill Standard Operating Procedures 5.4.1 Onsite Protective Actions 5.4.1.1 Personnel Evacuation andAccountabilitv For each type of accident Section 2.1 and Appendices through include Criteria for ordering an evacuation The means and time required to notify persons involved Evacuation routes transportation of personnel Locations of onsite and offsite assembly areas Search and rescue Monitoring of evacuees for contamination and control measures if contamination is found Criteria for command center and assembly area evacuation and reestablishment at alternate location Procedures for evacuating and treating injured personnel including contaminated personnel and Provisions for determining and maintaining the accountability of assembled and evacuated personnel E-40 5.4.1.2 Use of Protective Equipment and Supplies Section 2.1 and Appendices through specify the required protective equipment and supplies to the extent not already covered by Mill Standard Operating Procedures To the extent that Section 2.1 and Appendices through do not specify protective equipment and supplies then protective equipment and supplies normally required or available under existing Mill Standard Operating Procedures for the required procedure or activity will apply In addition to normal supplies of equipment at the Mill such as respirators protective clothing etc the Mill maintains supplies of specialized equipment in certain locations for use in emergency situations as follows Fire Hose Fire hose cabinets are located at the following sites with minimum of 300 feet of 2-1/2 hose two spanner wrenches spray nozzles and one hydrant wrench South of SX West of CCD North of mill building East of pulp storage tanks Northwest of Maintenance Shop West of Warehouse and East of office building Self Contained Breathing Apparatus Two Self-Contained Breathing Apparatus SCBA units are located at each of the following locations Hose station east of office building Hose Station South of SX North End SX Outside Wall and North end of mill building outside wail Spill Clean-up Equipment Barrels of soda ash are located throughout the Mill to be used in case of chemical spill Soda ash is also stored in bulk if needed There are also few drums of absorbent stored near the laboratory The laboratory also contains acid spill kits and absorbent materials to be used in case of spill E-41 Fire Fighting PPE Two complete sets of turnout gear for firefighting andlor emergency extrication are located in the Fire Hose Station located on the east side of the office building Maintenance of Emergency Equipment Fire extinguishers are inspected on an annual basis as well as the fire pump system The Mill Safety Coordinator performs regular spot checks on the emergency equipment locations to ensure that all of the equipment is in place Extinguishers are serviced on an annual basis and then checked monthly to make sure units are still charged The SCBA units are also checked monthly and then pressure tested every five years 5.4.1.3 Contamination Control Measures Because of the nature of potential accidents that can occur at dranium mills it is unlikely that an accident would result in significant risk of overexposure to any workers or members of the public see the conclusions of NRC staff in NUREG-1140 discussed in section 2.1.6 above Therefore the Mills existing Standard Operating Procedures are considered adequate for preventing further spread of radioactive materials and for minimizing radiation exposures from radioactive materials that could be unshielded or released by abnormal conditions Section 2.1 and Appendices through describe isolation area access control and application of criteria for permitting return to normal use to the extent necessary and not otherwise covered by existing Standard Operating Procedures for the types of accidents that could occur at the Mill 5.4.2 Offsite Protective Actions Section 2.1 and Appendices through describe the conditions that would require protective actions offsite for the various types of accidents and describe the protective action recommendations that would be made to offsite authorities when each recommendation would be made and what area offsite would be affected 5.5 Exposure Control in Radiological Emergencies Given the radioactive materials found at the Mill and the types of postulated accidents it is not likely that Mill personnel or offsite workers would be exposed to levels of radiation that cannot be adequately addressed under existing Mill Standard Operating Procedures 5.5.1 Emergency Radiation Exposure Control Program 5.5.1.1 Radiation Protection Program During the emergency situation the Radiation Protection Manual SOP Book will be the guide for all decontamination and exposure monitoring E-42 The Mills RSO will be responsible for the determination of exposures to be allowed during the event of an emergency situation This includes the unlikely event of authorizing workers to receive emergency doses and for permitting onsite volunteers to receive radiation doses in the course of carrying out lifesaving and other emergency activities 5.5.1.2 Exposure Guidelines The onsite exposure guidelines to be used for all postulated accidents including actions to control fires stop releases or protect facilities will be those set out ih UAC R3 13-15 and the Mills Radiation Protection Manual These exposure guidelines will also apply to Removing injured persons Undertaking mitigating actions Providing onsite first ald Performing personnel decontamination Providing ambulance service and Providing offsite medical treatment 5.5.1.3 Monitoring DUSA will provide all needed instrumentation for determining doses received by individuals during all emergency situations DUSA will also provide OSL badge monitoring to those emergency response individuals during situations that may require extended periods of exposure to high radiation areas In the event of an accident such as an accident that involved the dispersion of yellowcake or fire in the SX building or elsewhere on the facility that could involve the dispersion of radioactive materials breathing zone samples will be taken if practicable in the circumstances DUSA emergency personnel will be provided with respiratory protection where appropriate The Mill does not supply respiratory protection to personnel from offsite response organizations Those organizations must supply their own respiratory protection Mill Radiation Safety Staff will advise personnel from offsite organizations of the specific radiological precautions that need to be taken for the various response activities Radiation safety personnel will also monitor various areas of the facility occupied by emergency personnel to the extent practicable Bioassays of DUSA and offsite response personnel will be performed as necessary Records of dose and dose commitments will be malntalned for Mill personnel and offsite support organizations emergency workers involved in the accident E-43 5.5.1.4 Decontamination of Personnel Any emergency response equipment that enters the Mills Restricted Area in response to an incident will be scanned and decontaminated prior to leaving the site according to the requirements found in Table of the NRCs Policy and Guidance Directive FC-85-23 Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct Source or Special Nuclear Material issued May 1987 Any personnel leaving the Mills restricted area or otherwise exposed to radiation from the incident will be scanned and decontaminated in accordance with the procedures set out in the Mills Radiation Protection Manual for personnel leaving the Mills restricted area Injured personnel will be evaluated for radiation contamination at the earliest convenience if there is potential for contamination Should it be necessary contaminated articles will be gathered by the radiological staff after medical treatment has been rendered If the personnel cannot be decontaminated the clinic/hospital personnel will be notified in advance Mill radiation safety personnel will be available to provide health physics support clinic/hospital personnel 5.6 Medical Transportation One fully-equipped First Responder Unit Ambulance is located west of the office building Other motor pool vehicles on the property will be utilized as needed in emergency situations with support as needed from the local Emergency Medical Services All transportation vehicles will be surveyed and decontaminated by the Radiation Department at the Mill Any emergency response equipment or personnel that enters the Restricted Area in response to an incident will be scanned and decontaminated prior to leaving the site according to the requirements found in Table of the NRCs Policy and Guidance Directive FC-85-23 Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct Source or Special Nuclear Material issued May 1987 If any injured personnel who may also be radiologically contaminated will be transported to medical treatment facilities the inside of the transport vehicle will also be scanned and decontaminated in accordance with the foregoing Guidance Injured personnel will be evaluated for radiation contamination if there was potential for contamination at the earliest convenience Should it be necessary contaminated articles will be gathered by the radiological staff after medical treatment has been rendered If the personnel cannot be decontaminated clinic/hospital personnel will be notified in advance E-44 5.7 Medical Treatment All medical facilities will be made aware of potential radiological and chemical hazards associated with the postulated accidents described in Section 2.1 St Marys hospital in Grand Junction Colorado approximately hours drive by highway is the nearest trauma center Specialized medical attention for radioactive contamination or chemical exposure would be located either in Salt Lake City at the University of Utah Medical Center approximately hours drive by highway or in Denver Colorado approximately hours drive by highway All facilities are aware that DUSA will take responsibility for the monitoring and potential decontamination of all facilities contaminated during these emergencies The Mill will provide ambulance and hospital personnel with health physics support if needed E-45 EMERGENCY RESPONSE EQUIPMENT AND FACILITIES 6.1 Command Center When the evacuation alarm sounds or when personnel are verbally notified by radio or other means all personnel will assemble at The parking lot south of the office The Scalehouse North side of Tailings Cell or North of the Mill The assembly site will depend upon conditions i.e nature of the emergency wind conditions etc The Incident Commander RSOIFire Chief or Shift Foreman will specify the appropriate assembly site The Mill does not have specific communication or assessment center Key personnel are equipped with handheld VFIF transceivers which will serve as the primary means of communication while personnel are assembling to the designated relocation areas and as needed thereafter to deal with the emergency The relocation area will serve as the initial assessment center Other communications and assessment centers will be set up in the Mills office building Scalehouse Warehouse or other areas of the Mill that have communication capability as needed depending on the nature and location of the emergency 6.2 Communications Equipment 6.2.1 Onsite Communications Employees will be notified to evacuate the area by dialing 184 on any area telephone and announcing that the Mill should be evacuated This announcement will be repeated three times When the paging system cycles through the evacuation siren continuous frequency will automatically sound for approximately forty-five seconds and then automatically shut off allowing communications by radio from that point If the 184 number is dialed accidentally the evacuation alarm may be canceled by disconnecting the phone until the page cycle ends then re dial 184 See Exhibits and 2. The primary onsite communications will be by radio throughout the course of the emergency and the subsequent recovery Onsite communication by radio is the typical day-to-day manner of communication within the Mill facility and is performed by individual hand held VHF transceivers There is no central relay or similar system that could be disabled in the event of an emergency As result there is no need to provide for an alternative onsite communication system or perform operational tests of that communications system E-46 6.2.2 Offsite Communications During an emergency situation DUSAs onsite ambulance is equipped with radio to communicate with the San Juan County Dispatch This service provides backup means of offsite communication other than commercial telephone and will allow the Mill to be in communication with all emergency response services Operational tests are conducted on this system periodically during the normal weekly operational checks of the onsite ambulance 6.3 Onsite Medical Facilities The Mill maintains medical supplies at the site for typical occupational injuries as required by MSHA One fully-equipped First Responder Unit Ambulance is located west of the office building Li Other motor pool vehicles on the property will be utilized as needed in emergency situations with support as needed from the local Emergency Medical Services Given the types of accidents identified it is unlikely that any personnel would require contamination control over and above the controls set out in the Mills Radiation Protection Manual which would be applied to injured personnel If it is not possible or there is not sufficient time to decontaminate individuals then advance notice will be applied to offsite medical personnel and facilities In addition Mill personnel will be available to provide health physics assistance to such medical personnel if necessary 6.4 Emergency Monitoring Equipment The monitoring equipment used on day-to-day basis by the Radiation Safety Department will be available to monitor personnel and perform area monitoring as well as to assess the release of radioactive materials to the environment As discussed in Section 2.1.6 above none of the postulated accidents described in Section 2.1 above is expected to release significant quantities of radionuclides into the environment The greatest risk of that would be fire in the solvent extraction building but as NRC concluded in NUREG-1 140 the potential for overexposures offsite would not be significant Mill personnel will monitor to assess the magnitude and dispersion of any releases after the fact by use of hand held gamma meters in the areas offsite that could have been impacted The existing high volume particulate stations will also provide some information on the magnitude and dispersion of any such releases Onsite area monitoring and personnel scanning will be performed by use of existing monitoring equipment which is located in the Radiation Safety Department This is considered to be as non-hazardous location as possible at the site because it is not located particularly close to any locations that could involve one of the postulated accidents E-47 Mill Radiation Safety Staff will use dragger tubes primarily to detect dangerous levels of anhydrous ammonia and propane and other chemically toxic materials If necessary monitoring personnel will be equipped with SCBA respiratory protection while performing such monitoring E-48 MAINTAINING EMERGENCY PREPAREDNESS CAPABILITY 7.1 Written Emergency Plan Procedures This Plan will be reviewed annually by the RSO and if required updated by the ALARA Committee The SERP Committee will then validate all changes that are being requested before such changes will be implemented into new revision of this Plan After final SERP approval changes will be updated to the Document Control System The Document Control supervisor will update this Plan and then amend all current copies of the Plan to the recipients listed on the Distribution List at the beginning of this document 7.2 Training Semi-annual training for the emergency response teams will fr conducted This training will include but not be limited to fire suppression emergency medical services evacuation under hazardous atmosphere conditions search and rescue proper PPE usage during each potential emergency situation and radiological contamination surveying onsite and offsite Each member of the emergency response team will be assigned his or her tasks and trained in detail about those tasks The Radiation Staff will be trained in the proper decontamination of personnel PPE and potentially offsite medical facilities All employees onsite will be trained in the use of respiratory protection and on radiological hazards during their normal monthly safety meetings and as needed during special radiation training sessions as processes change at the facility Because appropriately trained Mill personnel will be in attendance at the Mill to accompany any offsite emergency response personnel there is no need to provide periodic orientation tours of the facility to such personnel 7.3 Drills and Exercises Quarterly drills as required by MSHA are conducted by the Safety and Radiation Departments to monitor performance of personnel responding to emergency situations Each drill is enacted upon one or more of the potential emergencies contemplated by this Plan The drill and evacuation activities are documented by the Mills Safety Coordinator and maintained within plant files Management reviews all drills at quarterly ALARA Committee Meetings Because the impacts associated with most types of emergencies that could occur at the Mill are limited to the Mill site itself and the risks to the public are very low offsite agencies are not typically invited to participate in any drills or exercises at the Mill E-49 7.3.1 Biennial Exercises Commencing in 2010 training exercises will be held every two years with the potential offsite emergency responders These exercises consist of training and information pertaining to the operational activities at the time 7.3.2 Quarterly Communications Checks Quarterly communication checks with all potential offsite emergency responders will be performed The communication checks will be documented and housed in the Safety Department records These checks will update any changes to contact information for needed parties Emergency response groups that are required to be contacted are Blanding Police Department .1 Blanding City Fire Department San Juan County Sheriff San Juan County EMS All local medical clinics and or hospitals and Utah Highway Patrol 7.4 Critiques This Plan is subject to audit by the ALARA audit team see Section 7.5 below and the periodic drills and exercises referred to in Section 7.3 above are subject to review periodically by the Mills ALARA Committee Given the nature of the potential incidents that could occur at the Mill and the low risk to the public relative to incidents that could occur at other types of facilities such as nuclear power reactors the Mill does not require that critique be prepared for each drill and exercise by one or more of the nonparticipating observers other than the audits and reviews conducted by the ALARA Audit Committee and the ALARA Committee 7.5 Independent Audit This Plan including all procedures training activities emergency facilities equipment and supplies and records associated with offsite support agency interface described therein is subject to annual review by the Mills ALARA audit team The Mills ALARA audit team is comprised of DUSA corporate environmental and safety personnel who do not have direct responsibilities for implementing the emergency response program as well as an independent outside consultant with expertise in environmental and radiation safety matters Any recommendations or deficiencies observed by the ALARA audit team will be presented to the ALARA Committee for consideration typically within approximately 60 days after the audit has been completed Decisions by the Mills ALARA Committee to make any changes to this Plan will be submitted to the Mills SERP for implementation Any changes in plant layout E-50 process or facilities are included in the types of changes that will be reviewed and could warrant revision to this Plan 7.6 Maintenance and Inventory of Emergency Equipment Instrumentation and Supplies Fire extinguishers as well as the fire pump system are inspected on an annual basis The Mill Safety Coordinator performs regular spot checks on the emergency equipment locations to ensure that all of the equipment is in place Extinguishers are serviced on an annual basis and then checked monthly to make sure units are still charged The SCBA units are also checked monthly and then pressure tested every five years 7.7 Letters of Agreement Any changes to this Plan that would impact the actions of any offsite response organizations will be communicated to such organizations The Mill will review all letters of agreement with offsite agencies periodically to ensure that they are kept up to date and in force E-5 RECORDS AND REPORTS 8.1 Records of Incidents written report will be prepared for all incidents of abnormal operation equipment failure and accidents that led to plant emergency that is classified as an Alert or Site Area Emergency The report will include the cause of the incident personnel and equipment involved extent of injury and damage onsite and offsite resulting from the incident all locations of contamination with the final decontamination survey results corrective actions taken to terminate the emergency and the action taken or planned to prevent recurrence of the incident The report will also include the onsite and offsite support assistance requested and received as well as any program changes resulting from the lessons learned from any critique of emergency response activities All such reports unique to radiological emergency not covered by existing regulations or License conditions will be retained until the License is terminated The foregoing reports will be prepared under the direction of the RSO and will be maintained in the Mills files for inspection 8.2 Records of Preparedness Assurance Records will be maintained in accordance with all MSHA State of Utah and ALARA criteria These documents will be available on site and housed in the Safety Department for review E-52 RECOVERY AND PLANT RESTORATION The Incident Commander will make the determination as to when the facility has been restored to safe status In making this determination the Incident Commander will Assess the damage to and the status of the facilitys capabilities to control radioactive materials and hazardous materials Specifically the Incident Commander must be satisfied that all safety-related equipment required for safe occupation and use of the facility in those areas to be occupied and used e.g radiation monitoring instruments respiratory protection equipment fire-suppression and fire-fighting equipment containments and air filters have been checked and restored to normal operations The Incident Commander will be assisted by the RSO the Safety Coordinator and the Maintenance Supervisor or Maintenance Forman in making these determinations and ii Determine the actions necessary to reduce any ongoing releases of radioactive or other hazardous material and to prevent further incidents The Incident Commander will be assisted by the RSO the Safety Coordinator and the Maintenance Supervisor or Maintenance Forman in making these determinations The Incident Commander will direct the resources and personnel required in order to accomplish the tasks to meet any required restoration action During any planned restoration operations personnel exposures to radiation will be maintained within UAC R3 13-15 limits and as low as is reasonably achievable E-53 10 COMPLIANCE WITH COMMUNITY RIGHT-TO-KNOW ACT AND CLEAN AIR ACT 10.1 Community Right to Know Act Section 11002 and 11004 of the Emergency Response and Community Right to Know Act EPCRA of 1986 42 U.S.C 11001 et seq requires that notice be given to the community emergency response coordinator for the local emergency planning committee in the event of release of an extremely hazardous substance offsite This requirement does not apply to any release which results in exposure to persons solely within the sites or sites within which the facility is located The Mill maintains inventories of two extremely hazardous substances anhydrous ammonia and propane Mill personnel are required to provide notice to the community response coordinator for the local emergency planning committee in the event of an offsite release of either of those two substances See Sections 2.1.1 2.1.2 and 2.1.3 above and Appendices and 10.2 Clean Air Act When Congress passed the Clean Air Act Amendments of 1990 Section 12r required EPA to publish regulations and guidance for chemical accident prevention at facilities using substances that posed the greatest risk of harm from accidental releases These regulations require facilities such as the Mill that use store or otherwise handle threshold quantity of certain listed regulated flammable and toxic substances to develop Risk Management Program known as Risk Management Plan The Mill uses stores and handles threshold quantities of two substances listed under the regulations promulgated under Section l2r of the Clean Air Act anhydrous ammonia and propane and has submitted to EPA Risk Management Plan for those two substances copy of that Risk Management Plan is attached as Appendix to this Plan E-54 APPENDIX EMERGENCY RESPONSE PROCEDURE FOR RELEASE OF ANHYDROUS AMMONIA See also Section 2.1.1 of the Emergency Response Plan The following steps will be followed for an uncontrolled release of anhydrous ammonia The steps should be followed in the order set out below unless more than one crew is mobilized in which case some of the steps can be taken simultaneously by different crews The Incident Commander has the authority to vary from the steps set out below if he deems it necessary in the circumstances to protect public health safety or the environment CAUTION INHALATION OF ANYDROUS AMMONIA CAN CAUSE INCAPACITATION SERIOUS INJURY AND DEATH release of anhydrous ammonia would most likely occur suddenly The person who would first witness the release should immediately contact his or her supervisor who would activate the evacuation alarm by using the dial 184 notification system Evacuate all personnel from the Mill site to location upwind of the spill and account for all personnel including all contractors and visitors at the Mill and all ore product and reagent truck drivers in accordance with the Emergency Evacuation and Shutdown Procedure described in Appendix Determine Incident Commander The Incident Commander will be the Mill Manager or in his absence the Mill Superintendent or in the absence of both the Mill Manager and the Mill Superintendent the RSO Shift Foremen are in charge and are responsible for all emergency procedures until the Incident Commander arrives Determine crews that may be required see Section 4.2.2 of the Plan for discussion of the available crews at the disposal of the Incident Commander Mobilize trained personnel and emergency equipment such as SCBAs first aid equipment etc See U.S Department of Transportation Pipeline and Hazardous Materials Safety Administration 2008 Emergency Response Guidebook the DOT Guidebook for appropriate protective clothing In that Guidebook Anhydrous ammonia has an ID No of 1005 and is covered by Guide No 125 copy of Guide 125 is attached to this Appendix Initiate rescue operations for any people who may be trapped by the release do this only with properly trained and equipped personnel A-3 Attend to any injured persons One of the following EMT-trained personnel should be contacted if they are on-site to aid in the event of any injuries to personnel David Turk Move victim to fresh air Give artificial respiration if victim is not breathing Do not use mouth-to-mouth method if victim ingested or inhaled the substance give artificial respiration with the aid of pocket mask equipped with one-way valve or other proper respiratory medical device Administer oxygen if breathing is difficult Remove and isolate contaminated clothing and shoes In case of contact with liquefied gas thaw frosted parts with lukewarm water In case of contact with substance immediately flush skin or eyes with running water for at least 20 minutes Control any bleeding Treat for shock if necessary Immobilize any fractures and stabilize for transportation Scan the injured for excessive alpha prior to transporting if time allows if alpha is excessive or there is no time to scan notify the clinic/hospital personnel and the RSO Keep victim warm and quiet Keep victim under observation Effects of contact or inhalation may be delayed The Safety Coordinator or Safety Technician will notify the following as needed Blanding Clinic 678-2254 or 678-3434 930 400 San Juan Hospital Monticello 678-2830 or 587-2116 364 1st Ambulance Service Blanding Dial 911 Ensure that medical personnel are aware of the materials involved and take precautions to protect themselves and if the Mill ambulance is used an attendant must ride with the injured person in addition to the driver except where the injured person could normally be transported in car or pickup Initiate necessary steps to contain and/or neutralize the release such as spraying with water fog turning off valves etc See Material Safety Data Sheet attached to this Appendix and See Exhibit for list and locations of main shut-off valves Guard against possible fires by shutting off electrical circuits isolating gas lines and eliminating ignition sources from affected areas 10 if the incident involves an uncontrolled release of 100 pounds 20 gallons or more of anhydrous ammonia the incident is classified as Site Area Emergency and could pose A-3 hazard to the public if the incident involves an uncontrolled release of between 35 pounds gallons and up to 100 20 gallons of anhydrous ammonia it is classified as an Alert In either case notify the community emergency response coordinator for the local emergency planning committee as soon as possible within 15 minutes after declaration of the emergency if possible as follows Rick Bailey 587-3225 work 587-2313 home Also make the following notifications as soon as possible Blanding Fire House and Sheriffs office Blanding Fire 350 West 200 South Blanding Phone number is 911 Sheriffs Office 297 West South Main Monticello

the notification should advise of the expected quantity of anhydrous ammonia released and provide the Mills initial recommendation for offsite protective actions which are that the offsite response authorities should follow the recommendations for releases of anhydrous ammonia contained in the DOT Guidebook In the DOT Guidebook Anhydrous ammonia has an ID No of 1005 and is covered by Guide No 125 Initial isolation and protective action distances are set out in Table to the DOT Guidebook Copies of the relevant portions of the Guidebook are attached to this Appendix An uncontrolled release of the contents of one of the anhydrous ammonia tanks at the Mill would be similar to an uncontrolled release from rail car or tanker truck and would be considered to be large spill under Table of the DOT Guidebook The foregoing offsite officials should also be advised of the conclusions of the Mills Risk Management Plan attached hereto as Appendix as it relates to anhydrous ammonia 11 if the incident involves an uncontrolled release of greater than 35 pounds gallons of anhydrous ammonia report the release to the State of Utah Division of Radiation Control 801-536-4250 during business hours or after hours to the UDEQ Duty Officer at 801-536- 123 immediately after notification of offsite authorities and in any event within one hour A-3 after declaration of the emergency if possible This immediate notification is required because an uncontrolled release of anhydrous ammonia of greater than 35 pounds gallons and up to 100 pounds 20 gallons is classified as an Alert and release of 100 pounds 20 gallons or more is classified as Site Area Emergency 12 Notification of Mill Management The Incident Commander will notify one of the following of all incidents if not already alerted

Some of these materials may react violently with water Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices Containers may explode when heated Ruptured cylinders may rocket CALL Emergency Response Telephone Number on Shipping Paper first If Shipping Paper not available or no answer refer to appropriate telephone number listed on the inside back cover As an immediate precautionary measure isolate spill or leak area for at least 100 meters 330 feet in all directions Keep unauthorized personnel away Stay upwind Many gases are heavier than air and will spread along ground and collect in low or confined areas sewers basements tanks Keep out of low areas Ventilate closed spaces before entering PROTECTIVE CLOTHING Wear positive pressure self-contained breathing apparatus SCBA Wear chemical protective clothing that is specifically recommended by the manufacturer It may provide little or no thermal protection Structural firefighters protective clothing provides limited protection in fire situations ONLY it is not effective in spill situations where direct contact with the substance is possible EVACUATION Spill Fire If tank rail car or tank truck is involved in fire ISOLATE for 1600 meters mile in all directions also consider initial evacuation for 1600 meters mile in all directions Page 196 See Table Initial Isolation and Protective Action Distances for highlighted materials For non-highlighted materials increase in the downwind direction as necessary the isolation distance shown under PUBLIC SAFETY ML LI TOXIC may be fatal if inhaled ingested or absorbed through skin Vapors are extremely irritating and corrosive Contact with gas or liquefied gas may cause burns severe injury and/or frostbite Fire will produce irritating corrosive and/or toxic gases Runoff from fire control may cause pollution PUBLIC SAFETY FIRE Small Fire Dry chemical or 002 Large Fire Water spray fog or regular foam Move containers from fire area if you can do it without risk Do not get water inside containers Damaged cylinders should be handled only by specialists Fire involving Tanks Fight fire from maximum distance or use unmanned hose holders or monitor nozzles Cool containers with flooding quantities of water until well after fire is out Do not direct water at source of leak or safety devices icing may occur Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank ALWAYS stay away from tanks engulfed in fire SPILL OR LEAK Fully encapsulating vapor protective clothing should be worn for spills and leaks with no fire Do not touch orwalk through spilled material Stop leak if you can do it without risk If possible turn leaking containers so that gas escapes rather than liquid Prevent entry into waterways sewers basements or confined areas Do not direct water at spill or source of leak Use water spray to reduce vapors or divert vapor cloud drift Avoid allowing water runoff to contact spilled material Isolate area until gas has dispersed FIRST AID Move victim to fresh air Call 911 or emergency medical service Give artificial respiration if victim is not breathing Do not use mouth-to-mouth method if victim ingested or inhaled the substance give artificial respiration with the aid of pocket mask equipped with one-way valve or other proper respiratory medical device Administer oxygen if breathing is difficult Remove and isolate contaminated clothing and shoes In case of contact with liquefied gas thaw frosted parts with lukewarm water In case of contact with substance immediately flush skin or eyes with running water for at least 20 minutes In case of contact with Hydrogen fluoride anhydrous UN1052 flush skin and eyes with water for minutes then for skin exposures rub on calcium/jelly combination for eyes flush with water/calcium solution for 15 minutes Keep victim warm and quiet Keep victim under observation Effects of contact or inhalation may be delayed Ensure that medical personnel are aware of the materials involved and take precautions to protect themselves Page 197 HOW TO USE TABLE INITIAL ISOLATION AND PROTECTIVE ACTION DISTANCES The responder should already have Identified the material by its ID Number and Name if an ID Number cannot be found use the Name of Material index in the blue-bordered pages to locate that number Found the three-digit guide for that material in order to consult the emergency actions recommended jointly with this table Noted the wind direction Look in Table the green-bordered pages for the ID Number and Name of the Material involved in the incident Some ID Numbers have more than one shipping name listed look for the specific name of the material If the shipping name is not known and Table lists more than one name for the same ID Number use the entry with the largest protective action distances Determine if the incident involves SMALL or LARGE spill and if DAY or NIGHT Generally SMALL SPILL is one which involves single small package e.g drum containing up to approximately 200 liters small cylinder or small leak from large package LARGE SPILL is one which involves spill from large package or multiple spills from many small packages DAY is any time after sunrise and before sunset NIGHT is any time between sunset and sunrise Look up the INITIAL ISOLATION DISTANCE Direct all persons to move in crosswind direction away from the spill to the distance specifiedin meters and feet Spill Page 298 Initial Isolation Initial Isolation Distance Look up the initial PROTECTIVE ACTION DISTANCE shown in Table For given material spill size and whether day or night Table gives the downwind distancein kilometers and miles for which protective actions should be considered For practical purposes the Protective Action Zone i.e the area in which people are at risk of harmful exposure is square whose length and width are the same as the downwind distance shown in Table Initiate Protective Actions to the extent possible beginning with those closest to the spill site and working away from the site in the downwind direction When water- reactive TIH producing material is spilled into river or stream the source of the toxic gas may move with the current or stretch from the spill point downstream for substantial distance The shape of the area in which protective actions should be taken

PROTECTIVE CLOTHING Street Clothing and Work Uniforms These garments such as uniforms worn by police and emergency medical services personnel provide almost no protection from the harmful effects of dangerous goods Structural Fire Fighters Protective Clothing SFPC This category of clothing often called turnout or bunker gear means the protective clothing normally worn by fire fighters during structural fire fighting operations It includes helmet coat pants boots gloves and hood to cover parts of the head not protected by the helmet and facepiece This clothing must be used with full-facepiece positive pressure self-contained breathing apparatus SCBA This protective clothing should at minimum meet the OSHA Fire Brigades Standard 29 CFR 1910.156 Structural fire fighters protective clothing provides limited protection from heat and cold but may not provide adequate protection from the harmful vapors or liquids that are encountered during dangerous goods incidents Each guide includes statement about the use of SFPC in incidents involving those materials referenced by that guide Some guides state that SFPC provides limited protection In those cases the responder wearing SFPC and SCBA may be able to perform an expedient that is quick in-and-out operation However this type of operation can place the responder at risk of exposure injury or death The incident commander makes the decision to perform this operation only if an overriding benefit can be gained i.e perform an immediate rescue turn off valve to control leak etc.The coverall-type protective clothing customarily worn to fight fires in forests or wildlands is not SFPC and is not recommended nor referred to elsewhere in this guidebook Positive Pressure Self-Contained Breathing Apparatus SCBA This apparatus provides constant positive pressure flow of air within the facepiece even if one inhales deeply while doing heavy work Use apparatus certified by NIOSH and the Department of Labor/Mine Safety and Health Administration in accordance with 42 CFR Part 84 Use it in accordance with the requirements for respiratory protection specified in OSHA 29 CFR 1910.134 Respiratory Protection and/or 29 CFR 1910.156 Fire Brigades Standard Chemical- cartridge respirators or other filtering masks are not acceptable substitutes for positive pressure self-contained breathing apparatus Demand-type SCBA does not meet the OSHA 29 CFR 1910.156 f1i of the Fire Brigades Standard If it is suspected that Chemical Warfare Agent CW is involved the use of NIOSH-certified respirators with CBRN protection are highly recommended Chemical Protective Clothing and Equipment Safe use of this type of protective clothing and equipment requires specific skills developed through training and experience It is generally not available to or used by first responders This type of special clothing may protect against one chemical yet be readily permeated by chemicals for which it was not designed Therefore protective clothing should not be used unless it is compatible with the released material This type of special clothing offers little or no protection against heat and/ or cold

of an ammonia explosion in building The steps should be followed in the order set out below unless more than one crew is mobilized in which case some of the steps can be taken simultaneously by different crews The Incident Commander has the authority to vary from the steps set out below if he deems it necessary in the circumstances to protect public health safety or the environment CAUTION INHALATION OF ANYDROUS AMMONIA CAN CAUSE INCAPACITATION SERIOUS INJURY AND DEATH An ammonia explosion would most likely occur suddenly The person who would first witness the explosion should immediately contact his or her supervisor who would activate the evacuation alarm by using the dial 184 notification system Evacuate all personnel from the Mill site to location upwind of the impacted area and account for all personnel including all contractors and visitors at the Mill and all ore product and reagent truck drivers in accordance with the Emergency Evacuation and Shutdown Procedure described in Appendix Determine Incident Commander The Incident Commander will be the Mill Manager or in his absence the Mill Superintendent or in the absence of both the Mill Manager and the Mill Superintendent the RSO Shift Foremen are in charge and are responsible for all emergency procedures until the Incident Commander arrives Determine crews that may be required see Section 4.2.2 of the Plan for discussion of the available crews at the disposal of the Incident Commander Mobilize trained personnel and emergency equipment such as SCBAs first aid equipment etc See U.S Department of Transportation Pipeline and Hazardous Materials Safety Administration 2008 Emergency Response Guidebook the DOT Guidebook for appropriate protective clothing In that Guidebook anhydrous ammonia has an ID No of 1005 and is covered by Guide No 125 copy of Guide 125 is attached to this Appendix Initiate rescue operations for any people who may be trapped as result of the explosion do this only with properly trained and equipped personnel Guard against possible fires by shutting off electrical circuits isolating gas lines and eliminating ignition sources from affected areas A-3 In the event of fire follow procedures set out on Guide No 125 If the fire is in the SX Building follow the procedures in Appendix in addition to the procedures in this Appendix Isolate utility lines affected by the fire 10 Extinguish the fire and post fire watch for flare-ups 11 In cases where the fire is not extinguished within thirty minutes of discovery the area must be barricaded off after extinguishing and left undisturbed until released by MSHA and DUSA management 13 Attend to any injured persons One of the following EMT-trained personnel should be contacted if they are on-site to aid in the event of any injuries to personnel David Turk Move victim to fresh air Give artificial respiration if victim is not breathing Do not use mouth-to-mouth method if victim ingested or inhaled the substance give artificial respiration with the aid of pocket mask equipped with one-way valve or other proper respiratory medical device Administer oxygen if breathing is difficult Remove and isolate contaminated clothing and shoes In case of contact with liquefied gas thaw frosted parts with lukewarm water In case of contact with substance immediately flush skin or eyes with running water for at least 20 minutes In case of bums immediately cool affected skin for as long as possible with cold water Do not remove clothing if adhering to skin Control any bleeding Treat for shock if necessary Immobilize any fractures and stabilize for transportation Scan the injured for excessive alpha prior to transporting if time allows If alpha is excessive or there is no time to scan notify the clinic/hospital personnel and the Radiation Safety Office Keep victim warm and quiet Keep victim under observation Effects of contact or inhalation may be delayed The Safety Coordinator or Safety Technician will notify the following as needed Blanding Clinic 678-2254 or 678-3434 930 400 San Juan Hospital Monticello 678-2830 or 587-2116 364 1st Ambulance Service Blanding Dial 911 Ensure that medical personnel are aware of the materials involved and take precautions to protect themselves and A-3 if the Mill ambulance is used an attendant must ride with the injured person in addition to the driver except where the injured person could normally be transported in car or pickup 14 Initiate necessary steps to contain and/or neutralize the release of ammonia that caused the explosion such as spraying with water fog turning off valves etc See Material Safety Data Sheet attached to this Appendix and See Exhibit for list and locations of the main shut-off valves 15 if the incident involves an uncontrolled release of 100 pounds 20 gallons or more of anhydrous ammonia the incident is classified as Site Area Eemergency and could pose hazard to the public if the incident involves an uncontrolled release of between 35 pounds gallons and 100 pounds 20 gallons of anhydrous ammonia it is classified as an Alert In either case notify the community emergency response coordinator for the local emergency planning committee as soon as possible within 15 minutes of declaration of the emergency if possible as follows Rick Bailey 587-3225 work 587-2313 home Also make the following notifications as soon as possible Blanding Fire House and Sheriffs office Blanding Fire 350 West 200 South Blanding Phone number is 911 Sheriffs Office 297 West South Main Monticello Phone number is 911 or 435 587-2237 Blanding Police Dial 911 678-2916 or 678-2334 Highway Patrol Dial 911 or 587-2000 In its notifications to the foregoing offsite officials the Mill personnel making the notification should advise of the expected quantity of anhydrous ammonia released and provide the Mills initial recommendation for offsite protective actions which are that the offsite response authorities should follow the recommendations for releases of anhydrous ammonia contained in the DOT Guidebook In the DOT Guidebook Anhydrous ammonia has an ID No of 1005 and is covered by Guide No 125 Initial isolation and protective A-3 action distances are set out in Table to the DOT Guidebook Copies of the relevant portions of the Guidebook are attached to this Appendix An uncontrolled release of the contents of one of the anhydrous ammonia tanks at the Mill would be similar to an uncontrolled release from rail car or tanker truck and would be considered to be large spill under Table of the DOT Guidebook The foregoing offsite officials should also be advised of the conclusions of the Mills Risk Management Plan attached hereto as Appendix as it relates to anhydrous ammonia 16 If the incident involves an uncontrolled release of greater than 35 pounds gallons of anhydrous ammonia report the release to the State of Utah Division of Radiation Control 801-536-4250 during business hours or after hours to the UDEQ Duty Officer at 801-536- 4123 immediately after notification of offsite authorities and in any event within one hour after declaration of the emergency if possible This immediate notification is required because an uncontrolled release of anhydrous ammonia of greater than 35 pounds gallons and up to 100 pounds 20 gallons is classified as an Alert and release of 100 pounds 20 gallons or more is classified as Site Area Emergency 17 Notification of Mill Management The Incident Commander will notify one of the following of all incidents if not already alerted and part of the Emergency

cannot be found use the Name of Material index in the blue-bordered pages to locate that number Found the three-digit guide for that material in order to consult the emergency actions recommended jointly with this table Noted the wind direction Look in Table the green-bordered pages for the ID Number and Name of the Material involved in the incident Some ID Numbers have more than one shipping name listed look for the specific name of the material If the shipping name is not known and Table lists more than one name for the same ID Number use the entry with the largest protective action distances Determine if the incident involves SMALL or LARGE spill and if DAY or NIGHT Generally SMALL SPILL is one which involves single small package e.g drum containing up to approximately 200 liters small cylinder or small leak from large package LARGE SPILL is one which involves spill from large package or multiple spills from many small packages DAY is any time after sunrise and before sunset NIGHT is any time between sunset and sunrise Spill Look up the initial PROTECTIVE ACTION DISTANCE shown in Table For given material spill size and whether day or night Table gives the downwind distancein kilometers and miles for which protective actions should be considered For practical purposes the Protective Action Zone i.e the area in which people are at risk of harmful exposure is square whose length and width are the same as the downwind distance shown in Table The responder should already have Look up the INITIAL ISOLATION DISTANCE Direct all persons to move in crosswind direction away from the spill to the distance specifiedin meters and feet Initial Isolation Initial Isolation Distance Initiate Protective Actions to the extent possible beginning with those closest to the spill site and working away from the site in the downwind direction When water- reactive TIH producing material is spilled into river or stream the source of the toxic gas may move with the

O m i PROTECTIVE CLOTHING Street Clothing and Work Uniforms These garments such as uniforms worn by police and emergency medical services personnel provide almost no protection from the harmful effects of dangerous goods Structural Fire Fighters Protective Clothing SFPC This category of clothing often called turnout or bunker gear means the protective clothing normally worn by fire fighters during structural fire fighting operations It includes helmet coat pants boots gloves and hood to cover parts of the head not protected by the helmet and facepiece This clothing must be used with full-facepiece positive pressure self-contained breathing apparatus SCBA This protective clothing should at minimum meet the OSHA Fire Brigades Standard 29 CFR 1910.156 Structural fire fighters protective clothing provides limited protection from heat and cold but may not provide adequate protection from the harmful vapors or liquids that are encountered during dangerous goods incidents Each guide includes statement about the use of SFPC in incidents involving those materials referenced by that guide Some guides state that SFPC provides limited protection In those cases the responder wearing SFPC and SCBA may be able to perform an expedient that is quick in-and-out operation However this type of operation can place the responder at risk of exposure injury or death The incident commander makes the decision to perform this operation only if an overriding benefit can be gained i.e perform an immediate rescue turn off valve to control leak etc.The coverall-type protective clothing customarily worn to fight fires in forests or wildlands is not SFPC and is not recommended nor referred to elsewhere in this guidebook Positive Pressure Self-Contained Breathing Apparatus SCBA This apparatus provides constant positive pressure flow of air within the facepiece even if one inhales deeply while doing heavy work Use apparatus certified by NIOSH and the Department of Labor/Mine Safety and Health Administration in accordance with 42 CFR Part 84 Use it in accordance with the requirements for respiratory protection specified in OSHA 29 CFR 1910.134 Respiratory Protection and/or 29 CFR 1910.156 Fire Brigades Standard Chemical- cartridge respirators or other filtering masks are not acceptable substitutes for positive pressure self-contained breathing apparatus Demand-type SCBA does not meet the OSHA 29 CFR 1910.156 f1i of the Fire Brigades Standard If it is suspected that Chemical Warfare Agent CW is involved the use of NIOSH-certified respirators with CBRN protection are highly recommended Chemical Protective Clothing and Equipment Safe use of this type of protective clothing and equipment requires specific skills developed through training and experience It is generally not available to or used by first responders This type of special clothing may protect against one chemical yet be readily permeated by chemicals for which it was not designed Therefore protective clothing should not be used unless it is compatible with the released material This type of special clothing offers little or no protection against heat and/ or cold Examples of this type of equipment have been described as Vapor Protective Page 348 Suits NFPA 1991 also known as Totally-Encapsulating Chemical Protective TECP Suits or Level protection OSHA 29 CFR 1910.120 Appendix and Liquid-Splash Protective Suits NFPA 1992 1993 also known as Level or protection OSHA 29 CFR 1910.120 Appendix or suits for chemical/biological terrorism incidents NFPA 1994 class or Ensembles No single protective clothing material will protect you from all dangerous goods Do not assume any protective clothing is resistant to cold and/or heat or flame exposure unless it is so

PROPANE See also Section 2.1.3 of the Emergency Response Plan The following steps will be followed for an uncontrolled release of propane The steps should be followed in the order set out below unless more than one crew is mobilized in which case some of the steps can be taken simultaneously by different crews The Incident Commander has the authority to vary from the steps set out below if he deems it necessary in the circumstances to protect public health safety or the environment CAUTION PROPANE IS EXTREMELY FLAMMABLE RISK OF FIRE OR EXPLOSION release of propane would most likely occur suddenly The person who would first witness the release should immediately contact his or her supervisor who would activate the evacuation alarm by using the dial 184 notification system Evacuate all personnel from the Mill site to location upwind of the spill and account for all personnel including all contractors and visitors at the Mill and all ore product and reagent truck drivers in accordance with the Emergency Evacuation and Shutdown Procedure described in Appendix Determine Incident Commander The Incident Commander will be the Mill Manager or in his absence the Mill Superintendent or in the absence of both the Mill Manager and the Mill Superintendent the RSO Shift Foremen are in charge and are responsible for all emergency procedures until the Incident Commander arrives Determine crews that may be required see Section 4.2.2 of the Plan for discussion of the available crews at the disposal of the Incident Commander Mobilize trained personnel and emergency equipment such as SCBAs first aid equipment etc See U.S Department of Transportation Pipeline and Hazardous Materials Safety Administration 2008 Emergency Response Guidebook the DOT Guidebook for appropriate protective clothing In that Guidebook propane has an ID No of 1075 and is covered by Guide No 115 copy of Guide 115 is attached to this Appendix Initiate rescue operations for any people who may be trapped by the release do this only with properly trained and equipped personnel In the event of spill or leak follow the procedures set out under the heading Spill or Leak in Guide No 115 A-3 Guard against possible fires by shutting off electrical circuits isolating gas lines and eliminating ignition sources from affected areas See Exhibit for list and locations of main shut-off valves In the event of fire follow procedures set out under the heading Fire in Guide No 115 10 Isolate utility lines affected by the fire 11 Extinguish the fire and post fire watch for flare-ups 12 In cases where the fire is not extinguished within thirty minutes of discovery the area must be barricaded off after extinguishing and left undisturbed until released by MSHA and DUSA management 13 Attend to any injured persons One of the following EMT-trained personnel should be contacted if they are on-site to aid in the event of any injuries to personnel David Turk Move victim to fresh air Give artificial respiration if victim is not breathing Administer oxygen if breathing is difficult Remove and isolate contaminated clothing and shoes Clothing frozen to the skin should be thawed before being removed In case of contact with liquefied gas thaw frosted parts with lukewarm water In case of burns immediately cool affected skin for as long as possible with cold water Do not remove clothing if adhering to skin Control any bleeding Treat for shock if necessary Immobilize any fractures and stabilize for transportation Scan the injured person for excessive alpha prior to transporting if time allows If alpha is excessive or there is no time to scan notify the clinic/hospital personnel and the Radiation Safety Office Keep victim warm and quiet The Safety Coordinator or Safety Technician will notify the following as needed Blanding Clinic 678-2254 or 678-3434 930 400 San Juan Hospital Monticello 678-2830 or 587-2116 364 1st Ambulance Service Blanding Dial 911 Ensure that medical personnel are aware of the materials involved and take precautions to protect themselves If the Mill ambulance is used an attendant must ride with the injured person in addition to the driver except where the injured person could normally be transported in car or pickup 4.3 14 If the incident involves an uncontrolled release of propane that could result in an explosion it is classified as an Alert As result notify the community emergency response coordinator for the local emergency planning committee as soon as possible within 15 minutes after declaration of the emergency if possible as follows Rick Bailey 587-3225 work 587-2313 home Also make the following notifications as soon as possible Blanding Fire House and Sheriffs office Blanding Fire 350 West 200 South

notifications to the foregoing offsite officials the Mill personnel making the notification should advise of the expected quantity of propane released and provide the Mills initial recommendation for offsite protective actions which are that the offsite response authorities should follow the recommendations for releases of propane contained in the DOT Guidebook In the DOT Guidebook propane has an ID No of 1075 and is covered by Guide No 115 Initial isolation and evacuation recommendations are set out in Guide No 115 Copies of the relevant portions of the DOT Guidebook are attached to this Appendix An uncontrolled release of the contents of the Mills propane tank would be similar to an uncontrolled release from rail car or tanker truck The foregoing offsite officials should also be advised of the conclusions of the Mills Risk Management Plan attached hereto as Appendix as it relates to propane 15 If the incident involves an uncontrolled release of propane that could result in an explosion report the release to the State of Utah Division of Radiation Control 801-536-4250 during business hours or after hours to the UDEQ Duty Officer at 801-536-4123 immediately after notification of offsite authorities and in any event within one hour after declaration of the emergency if possible This immediate notification is required because an uncontrolled release of propane that could result in an explosion is classified as an Alert A-3 16 Perform scans on personnel that may have been exposed to areas of high radiation Perform bioassays if appropriate 17 Notification of

followed in the order set out below unless more than one crew is mobilized in which case some of the steps can be taken simultaneously by different crews The Incident Commander has the authority to vary from the steps set out below if he deems it necessary in the circumstances to protect public health safety or the environment In the case of tornado 1.1 If you are in building Go to the center of an interior room on the lowest level away from corners windows doors and outside walls Put as many walls as possible between you and the outside Avoid areas close to process equipment and leach tanks Avoid the SX building if possible If possible get under sturdy table or cover yourself with some sort of thick padding to protect against falling debris in case the roof and ceiling fall and Crouch as low as possible to the floor facing down and cover your head with your hands 1.2 if you are in vehicle Get out immediately and go to the lowest floor of sturdy nearby building and follow the procedures in 1.1 above if it is not possible to get to nearby sturdy building then run to low ground away from any vehicles and trees and follow the instructions in 1.4 1.3 if you are in the Scalehouse or other similar mobile home or trailer Get out immediately You are safer out of the Scalehouse or similar structures than you are if you stay inside if possible go the nearest sturdy building and follow the instructions in 1.1 above if it is not possible to go to nearby sturdy building seek shelter on the open ground away from the Scalehouse or other similarbuilding and follow the instructions in 1.4 1.4 If you are out in the open if possible seek shelter in sturdy building if not lie flat and face-down on low ground such as in nearby ditch or depression Be aware of the potential for flooding A-3 Cover your head with your hands Get as far away from trees and vehicles as you can they may be blown onto you in tornado and Watch out for flying debris 1.5 After the tornado Stay away from damaged areas unless your assistance has been specifically requested by the Incident Commander Heavily damaged buildings and other structures could collapse at any time Stay away from power lines and puddles with wires in them they may still be carrying electricity Watch your step to avoid broken glass nails and other sharp objects Do not use any matches or lighters in case of leaking natural gas pipes or fuel tanks nearby and Open cabinets cautiously Beware of objects that can fall off the shelves In case of major earthquake Be aware that some earthquakes are actually foreshocks and larger earthquake might occur Minimize your movements to few steps to nearby safe place as outlined below and stay there until the shaking has stopped 2.1 if you are indoors DROP to the ground take COVER by getting under sturdy table or other piece of furniture and HOLD ON until the shaking stops if there isnt table or desk near you cover your face and head with your arms and crouch in an inside corner of the building Stay away from glass windows outside doors and walls and anything that could fall such as lighting fixtures furniture or equipment Use doorway for shelter only if it is in close proximity to you and if you know it is strongly supported loadbearing doorway Stay inside until the shaking stops and if is safe to go outside and Be aware that the electricity may go out or the sprinkler systems or fire alarms may turn on 2.2 if you are outdoors Stay there Move away from buildings streetlights and utility wires The greatest danger exists directly outside buildings at exits and alongside exterior walls and Once in the open stay there until the shaking stops A-3 2.3 if you are in moving vehicle Stop as quickly as safety permits and stay in the vehicle Avoid stopping near or under buildings trees overpasses and utility wires and Proceed cautiously once the earthquake has stopped Avoid roads bridges or ramps that might have been damaged by the earthquake 2.4 After the Earthquake Expect aftershocks These secondary shockwaves are usually less violent than the main quake but can be strong enough to do additional damage to weakened structures and can occur in the first hours days weeks or even months after the quake Stay away from damaged areas unless your assistance has been specifically requested by the Incident Commander Heavily damaged buildings and other structures could collapse at any time Stay away from power lines and puddles with wires in them they may still be carrying electricity Watch your step to avoid broken glass nails and other sharp objects and Do not use any matches or lighters in case of leaking natural gas pipes or fuel tanks nearby Determine Incident Commander The Incident Commander

Figure Mill Site Drainage Basins WHITE MESA MILL SPILL PREVENTION CONTROL AND COUNTERMEASURES PLAN FOR CHEMICALS AND PETROLEUM PRODUCTS 1.1 OBJECTIVE The objective of the Spill Prevention Control and Countermeasures SPCC Plan is to serve as site-specific guideline for the prevention of and response to chemical and petroleum spills and as guidance documeht for compliance with Groundwater Discharge Permit No UGW370004 The plan outlines spill potentials containment areas and drainage charapteristics of the White Mesa Mill site The plan addresses chemical spill prevention spill potentials spill discovery and spill notification procedures The Oil Pollution Prevention Sections of the Clean Water Act 40 CFR 112 to 117 also referred to as the Spill Prevention Control and Countermeasures SPCCrules establish requirements that apply to facilities which could reasonably be expected to discharge oil in quantities that may be harmful as described in that Act into or upon the navigable waters of the United States or that may affect natural resources of the United States Section 112 states that the Act is not applicable to facilities that are not subject to the authority of the Environmental Protection Agency EPA for one of the following reasons Due to its location the facility could not reasonably be expected to discharge oil into navigable waters of or impact natural resources of the U.S or The facility is subject to authority of the Department of Transportation as defined in Memorandum of Understanding MOU between the Secretary of Transportation and the EPA Administrator or The facility does not exceed either the underground or the above ground storage capacity 42000 gallons and 1320 gallons respectively prescribed in the rules The Mill could not reasonably be expected as described in the SPCC regulation to discharge oil into the navigable waters or impact natural resources of the U.S The Mill site was constructed with an overall grade and diversion ditch system designed to channel the non-recovered portion of any material spill to the tailings management system Hence it is not reasonable to expect that surface spills will ever reach navigable waters or natural resources of the U.S or Utah Therefore the SPCC reporting requirements in the Clean Water Act are not applicable to the Mill However as good environmental management practice the Mill has implemented the spill management program described in this document which is consistent with the intent of the Clean Water Act to the extent practicable Although the Mill by design cannot directly impact navigable waters of the U.S and as result spills that may occur but are retained within the site would not be reportable the Mill implements these practices in good faith effort to minimize all potential sources of pollution at the site Storage of ores and alternate feeds on the ore pad and containment of tailings in the Mill tailings impoundment system are not considered spills for the purposes of this SPCC Ammonia is the only chemical that has the potential to leave the site and would do so as vapor Figure Site Layout Map shows map of the mill site

illustrated in Figure The map shows drainage basin boundaries flow paths constructed diversion ditches tailings cells the spillway between Cell and dikes berms and other relevant features The White Mesa Mill is zero discharge facility for process liquid wastes The mill area has been designed to ensure that all spills or leaks from tanks will drain toward the lined tailings cells The tailings cells in turn are operated with sufficient freeboard minimum of three feet to withstand 100%of the PMP Probable Maximum Precipitation This allows for maximum of 10 inches of rain at any given time 1.4 DESCRIPTION OF BASINS Precipitation and unexpected spills on the mill property are contained within their respective drainage basins Runoff would ultimately drain into one of the three lined tailings cells 1.4.1 Basin Al Basin Al is north of Cell 1-I and Diversion Ditch No The basin contains 23 acres all of which drain into Westwater Creek This area is not affected by mill operations 14.2 Basin A2 Basin A2 contains all of Cell 1-I including an area south of the Diversion Ditch No The basin covers 84 acres Any runoff from this basin would be contained within Cell 1-I 1.4.3 Basin BI Basin Bl is north of the mill property and is not affected by mill operations The basin contains 45.4 tributary acres Runoff from this basin drains into flood retention area by flowing through Diversion Ditch No Diversion Ditch No drains into Westwater Creek 14.4 Basin B2 Basin B2 is northeast of the mill and contains only 2.6 acres Runoff from this basin would drain into Diversion Ditch No Diversion Ditch No ultimately drains into Diversion Ditch No This basin is not affected by mill operations 1.4.5 Basin B3 Basin B3 contains most of the mill area buildings ore stockpiles process storage tanks retention ponds spill containment structures pipelines and roadways The normal direction of flow in this basin is from the northwest to the southwest Any runoff from this basin would drain into Cell 1-I The basin contains 64 acres This basin has sufficient freeboard to withstand 100%of the PMP Probable Maximum Precipitation This allows 10 inches of rain for any given storm event 1.4.6 Basin Basin contains all of Cell The basin consists of 80.7 acres This basin contains earth stockpiles and the heayyequipment shop The direction of flow in this basin is to the southwest All runoff in this basin would be channeled along the southern edge of the basin Runoff would then flow into Cell via the spillway from Cell to Cell 1.4.7 Basin Basin contains all of Cell This basin consists of 78.3 acres including portion of the slopes of the topsoil stockpile and random stockpile The basin contains all flows including those caused by the PMF 1.4.8 Basin Basin contains Cell 4A and consists of 43.3 acres All anticipated flows including those caused by the PMF will be contained within the basin and will flow directly into Cell 4A 1.5 POTENTIAL CHEMICAL SPILL SOURCES AND SPILL CONTAINMENT This section details potential sources of chemical spills and reportable quantities For purposes of this SPCC reportable quantity will be defined as quantities listed below which could be expected to reach navigable waters of the United States Reportable Quantities are those identified in 40 CFR Part 117 Table 117.3 Reportable Quantities of Hazardous Substances Designated Pursuant to Section 311 of the Clean Water Act It is not expected that any spill would reach navigable waters of the United States However if spill of volume listed below occurs and remains on the mill site which is the more likely scenario then management is to be notifie so that proper internal evaluations of the spill are made 1.5.1 Reagent Tanks Tank list included in Table 2.0 1.5.2 Ammonia The ammonia storage tanks consist of two tanks with capacity of 31409 gallons each The tanks are located southeast of the Mill building Daily monitoring of the tanks for leaks and routine integrity inspections will be conducted to minimize the hazard associated with ammonia The reportable quantity for an ammonia spill is gallons Ammonia spills should be treated as gaseous Ammonia vapors will be monitored closely to minimize the hazard associated with inhalation If vapors are detected efforts will be made to stop or repair the leak expeditiously Ammonia is the only chemical as vapor that has the potential to leave the site 1.5.3 Ammonia Meta Vanadate Ammonia meta vanadate is present in the SX building as the process solutions move through the circuit to produce the vanadium end product But the primary focus will be on the transportation of this chemical The reportable quantity for an ammonia meta vanadate spill is 1000 pounds 1.5.4 Caustic Storage Sodium Hydroxide The caustic storage tank is located on splash pad on the northwest corner of the SX building The tank has capacity of 19904 gallons The tank supports are mounted on concrete curbed catchment pad that directs spills into the sand filter sump in the northwest corner of the SX building The reportable quantity for sodium hydroxide spill is 85 gallons 1.5.5 Sodium Carbonate Soda Ash The soda ash solution tank has capacity of 16921 gallons and is located in the northeast corner of the SX building The smaller soda ash shift tank has capacity of 8530 gallons and is located in the SX building Spills will be diverted into the boiler area and would ultimately drain into Cell 1-I There is no reportable quantity associated with sodium carbonate spill 1.5.6 Sodium Chlorate Sodium chlorate tanks consist of two fiberglass tanks located within dike east of the SX building The larger tank is used for dilution purposes and has maximum capacity of 17700 gallons The smaller tank serves as storage tank and has capacity of 10500 gallons Daily monitoring of the tanks for leaks and integrity inspections will be conducted to minimize the hazard associated with sodium chlorate Sodium chlorate that has dried and solidified becomes even more of safety hazard due to its extremely flammable nature The reportable quantity for sodium chlorate spill is 400 gallons 1.5.7 Sulfuric Acid The sulfuric acid storage tanks consist of one large tank with the capacity of 16000000 gallons and two smaller tanks with capacities of 269160 gallons each The large tank is located in the northwest corner of mill area basin B3 and is primarily used for acid storage and unloading The tank support for the large tank is on mound above depression which would contain significant spill All flows resulting would be channeled to Cell 1-I The tank is equipped with high level audible alarm which sounds prior to tank overflows concrete spill catchment with sump in the back provides added containment around the base of the tank However the catchment basin would not be able to handle major tank failure such as tank rupture The resulting overflow would flow towards Cell 1-I The two smaller storage tanks are located within an equal volume spill containment dike east of the mill building The tanks are not presently in use but are equipped with high level audible alarms The reportable quantity for sulfuric acid spill is 65 gallons 1000 pounds 1.5.8 Vanadium Pentoxide Vanadium pentoxide is produced when vanadium is processed through the drying and fusing circuits and is not present in the vanadium circuit until after the deammoniator Efforts will be made to minimize leaks or line breaks that may occur in processes in the circuit that contain vanadium pentoxide Special care will be taken in the transportation of this chemical The reportable quantity for vanadium pentoxide spill is 1000 pounds 1.5.9 Kerosene Organic The kerosene storage area is located in the central mill yard and has combined capacity of 10152 gallons in three tanks Any overflow from these three tanks would flow around the south side of the SX building and then into Cell 1-I These tanks have drain valves which remain locked unless personnel are supervising draining operations The reportable quantity for kerosene spill is 100 gallons 1.6.0 Used Waste Oil Used Waste oil for parts washing is located north of the maintenance shop in tank and has capacity of 5000 gallons The tank is contained within concrete containment system Ultimate disposal of the used oil is to an EPA permitted oil recycler Any oil escaping the concrete cbntainment system will be cleaned up Soil contaminated with used oil will be excavated and disposed of in Cell 1.6.1 Propane The propane tank is located in the northwest corner of the mill yard and has capacity of 30000 gallons Daily monitoring of the tank for leaks and integrity inspections will be conducted to minimize potential hazards associated with propane leaks Propane leaks will be reported immediately There is no reportable quantity associated with propane spill 1.7 POTENTIAL PETROLEUM SPILL SOURCES AND CONTAINMENT This section details potential sources of petroleum spills and reportable quantities For purposes of this SPCC reportable quantity will be defined as quantities listed below which could be expected to reach navigable waters of the United States It is not expected that any spill would reach navigable waters of the United States However if spill of volume listed below occurs and remains on the mill site which is the more likely scenario then management is to be notified so that proper internal evaluations of the spill are made 1.7.1 Petroleum Tanks 1.7.1.1 Diesel Two diesel storage tanks are located north of the mill building The tanks have capacities of 250 gallons each One of the diesel tanks is for the emergency generator The other tank is located in the pumphouse on an elevated stand Spillage from either tank would ultimately flow into Cell 1-I The reportable quantity for diesel spill is 100 gallons 1.7.2 Aboveground Fuel Pump Tanks 1.7.2.1 Diesel The diesel tank is located on the east boundary of Basin B3 and has capacity of 6000 gallons The tank is contained within concrete catchment pad The reportable quantity for diesel spill is 100 gallons 1.7.2.2 Unleaded Gasoline The unleaded gasoline tank is located next to the diesel tank The unleaded gasoline tank has capacity of 3000 gallons and is contained within the same containment system as the diesel tank The reportable quantity for an unleaded gasoline spill is 100 gallons 1.7.2.3 Pump Station Both the diesel and the unleaded gasoline tanks will be used for refueling company vehicles used around the mill site The pump station is equipped with an emergency shut-off device in case of overflow during fueling In addition the station is also equipped with piston leak detector and emergency vent Check valves are present along with tank monitor console with leak detection system The catchment is able to handle complete failure of one tank However if both tanks failed the concrete catchment pad would not be able to contain the spill In this case temporary berm would need to be constructed Absorbent diapers or floor sweep would be used in an effort to limit and contain the spill The soil would be cleaned up and placed in the authorized disposal area in Cell 1.7 2.4 Truck Unloading In the event of truck accident resulting in an overturned vehicle in the mill area proper reporting and containment procedures will be followed when warranted such as when oil or diesel fuel is spilled Proper clean-up procedures will be followed to minimize or limit the spill The spill may be temporarily bermed or localized with absorbent compounds Any soils contaminated with diesel fuel or oil will be cleaned up and placed in the authorized disposal area in Cell 1.8 SPILL DISCOVERY AND REMEDIAL ACTION Once chemical or petroleum spill has been detected it is important to take measures to limit additional spillage and contain the spill that has already occurred Chemical or petroleum spills will be handled as follows The Shift Foreman will direct efforts to shut down systems if possible to limit further release The Shift Foreman will also secure help if operators are requiring additional assistance to contain the spill The Shift Foreman is also obligated to initiate reporting procedures Once control measures have begun and personal danger is minimized the Shift Foreman will notify the Production Superintendent Maintenance Superintendent or Mill Manager The Production or Maintenance Superintendent will notify the Mill Manager who in turn will notify the Environmental Health and Safety Manager The Mill Manager will assess the spill and related damage and direct remedial actions The corrective actions may include repairs clean up disposal and company notifications Government notifications may be necessary in some cases If major spill continues uncontrolled these alternatives will be considered Construct soil dikes or pit using heavy equipment Construct diversion channel into an existing pond Start pumping the spill into an existing tank or pond Plan further clean-up and decontamination measures 1.9 SPILL INCIDENT NOTIFICATION 1.9.1 External Notification As stated in Section 1.1 spills are not expected to reach navigable waters of the United States If spill of

TRANSPORTATION ACCIDENT RESPONSE PLAN For URANIUM CONCENTRATE SPILL White Mesa Mill Date 2/07 Revision DUSA-I Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page of 43 PLAN SUMMARY TRANSPORTATION ACCIDENT RESPONSE PLAN FOR URANIUM CONCENTRATE Driver or carrier instructions will be given to each driver of each transprt leaving the plant site with load of uranium concentrate These instructions will consist of an explanation of the product preliminary precautions at the accident site whom to notify and what to do in case of fire In the event of transportation-related accident immediate containment of the product will be achieved by covering the spill area with plastic sheeting or equivalent material to prevent wind and water erosion If sheeting is not available and depending op where the spill occurs soil from the surrounding area may be used Perimeter ditching will be used to contain the spill if it should occur in an area where runoff could result from precipitation All human and vehicular traffic through the spill area will be restricted The area would be cordoned off if possible All persons not participating in the accident response will be restricted to 50 feet from the accident site Local law enforcement officers will be notified and may be asked to assist in controlling traffic and keeping unauthorized persons out of the spill area Covered containers and removal equipment i.e large plastic sheeting radioactive signs ropes hoses shovels vacuums axes stakes heavy equipment front-end loaders graders etc will be available to clean up the yellowcake If conditions warrant water will be applied to the spilled yellowcake in fine spray to assist in dust abatement Gloves protective clothing and any personal clothing contaminated during cleanup operations will be encased in plastic bags and kept in the plant area for decontamination or disposal Response team members will have thorough knowledge in basic first aid and of the physical hazards in inhalation ingestion or absorption of radionuclides Team members will adequately protect themselves The cleanup operation will involve removing small amounts of pavement topsoil and vegetation in the immediate area of the accident The material that will have to be removed from the affected area will be returned to the mill for reprocessing if possible or disposed of in manner approved by the NRC or the Executive Secretary Following cleanup of the affected area an alpha survey will be conducted to insure that radioactivity is within the limits outlined in NRC Guidelines for Decontamination of Facilities and Equipment prior to release for unrestricted use dated November 1976 An investigation will be conducted by the Radiation Protection Department Results and recommendations of the investigation and of the decontamination survey will be documented and maintained for at least five years The NRC will be notified promptly of

of 43 1.0 INTRODUCTION 1.1 Needs The Nuclear Regulatory Commission requires that uranium producers implement an emergency response plan for containment and cleandp of uranium concentrate spill Although the DOT regulations place the responsibility for these activities on the carrier the regulatory agencies have taken the position that the shipper has an obligation to assist because of his knowledge of the radioactive hazard of the concentrate 1.2 Scope Transportation accidents involving radioactive ipaterials such as yellowcake consist of the following four phases Initial During the first 15 to 30 minutes after the accident occurs emergency action is taken by local authorities local or state police to help the injured evaluate the problem and take action to prevent further contamination i.e rerouting traffic and crowd control Confinement This phase is accomplished by the transport vehicle operator or local service units to complete isolation or cover the spilled material make proper notification and identify contaminated areas Cleanup This action includes the removal of any radioactive material or contamination from the site and restoring it to original conditions This action is the carrier responsibility Cost Recovery The cost of cleanup and liability for damage to life and property are borne by the carrier The Companys emergency response plan must address confinement and cleanup activities outlined above the initial and cost recover phases are outside the scope of this manual 1.3 Description of Company Shipments The type of product shipped by

Wash Basins Bars Soap Washcloths Towels 6.0 PROCEDURES FOR HANDLING THE ACCIDENT Vehicle accidents involving yellowcake can be categorized in three basic radiological severity types as follows No apparent release of concentrate from its drum containers drums may or may not be outside the vehicle Concentrate is released from the drum but contained within the van Concentrate is spilled from its container outside the transport vehicle This characterization as it applies to UPL shipments consists of no apparent leakage from the tank trucks or spill of solution Section 6.9 outlines the procedures for handling this type of accident Situations arising from each of these accident types can be highly variable depending on Proximity of waterways and populated areas Weather conditions at the accident site The condition of the vehicle operator after the accident and Availability of local emergency response personnel police firemen etc. In view of these variables this section is intended as basic guide requiring certain judgmental decisions on case-by-case basis White Mesa Mill Date 2/07 Revision DUSA-l Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 17 of 43 6.1 Transport Vehicle Operator Driver Filling out the accident form and notifying the Director of Operations They Will then follow the following emergency instructions canied in his kit If there is not apparent leakage drums may or may not be thrown from the vehicle Caution people not to tamper with containers use civil authorities to assist if necessary and have them stay 10 to 15 feet away Containers lying on the rdad should be moved to the road edge if assistance can be obtained and Assure local authorities there is no danger in handling closed containers 6.2 Response Team Mobilization The response team leader will access available accident information and assemble the required personnel at the White Mesa Mill Office Required vehicle and facility keys are stored in the White Mesa Mill Office labeled Response Mobilization will be accomplished in the following sequence Obtain radiation monitoring/measuring equipment Section 5.3 Proceed to the Radiation Department storage containers Load emergency equipment in the vehicle Section 5.0 Obtain pool vehicles as required to transport all personnel and Proceed to the accident site The response team leader will check to make certain that available air samplers including filters flashlights and Geiger counters are dispatched with the plant representative 6.3 Emergency Containment Upon arrival at the accident site inform local authorities of your presence purpose and proposed activities Gather information regarding current status of activities and assign one individual to record this information as well as names White Mesa Mill Date 2/07 Revision DUSA-l Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 18 of 43 and positions of persons present at the site If the spilled material is not stabilized proceed with this activity in completing the procedures outlined in Section 6.1 6.4 Protective Clothing Protective clothing is normally required when spillage is evident The need and use for these are established by the response team leader on case-by-case basis Refer to Addendum for details He is also responsible for controlling maintaining decontamination testing and instructing in the proper use of protective clothing and respiratory protective equipment 6.5 Radiation Measurements and Sampling Response team members are trained in proper operation of portable radiation detectors as well as monitoring techniques Addendum Initial monitoring for spread of contamination is accomplished with portable open Window Geiger counters Additionally high volume air samples are located and activated 50 feet upwind and downwind from the spill 6.6 Establish Radiation Exclusion Area The boundaries of the yellowcake spill area whether inside the transport vehicle or outside are defined through combination of visual observation identifying yellow color and radiation monitoring GM detectors The area is then roped off leaving about ten feet between the tape barricade and the spill boundary and Caution Radioactive Materials signs are installed on the barricade The barricaded area is referred to as the radiation exclusion RADEX area and unauthorized equipment or personnel are not allowed to enter 6.7 Control Point base of operations where needed equipment or data is stored and maintained is established outside the RADEX area normally about ten feet away from the barricade This base is referred to as the control point The control point is also used as debriefing area and personnel contamination station White Mesa Mill Date 2/07 Revision DUSA-1 Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 19 of 43 6.8 Check Station Operation Receptacles plastic bags for used protective clothing and equipment are fastened to the inside tape barricade near the control point of the RADEX area This location is used as the only area where ingress and egress to the RADEX area is allowed and it is referred to as the check station One response team member is assigned to man the check station and his responsibilities are Assure only required people enter the area and they are properly equipped with protective clothing and respirators Section 6.4 When personnel exit the RADEX area thake certain protective clothing is properly removed and placed in receptacles with the shoe covers being the last items removed Monitor the persons exposed skin areas hands face etc and clothing using the alpha scintillation detector probe If personal clothing monitoring reveals contamination remove the involved clothing and monitor skin beneath it Collect nose swipes and monitor same if contamination is evident on nose swipes label urine sample bottle name and date and request donation at the earliest convenience follow up this sampling on 24-hour basis If monitoring reveals skin contamination direct the individual to the personnel decontamination station Equipment being removed from the RADEX area is monitored for alpha radiation at the check station and sealed in plastic bags or decontaminated if found contaminated 6.9 Transportation Accidents Involving IX Eluate or Uranium Product Liquor The shipment of solution in tank trnck is less hazardous than shipping U3O8 concentrate The reasons are as follows The activity released to the environment by spillage of the contents of the tank truck is approximately 8e-3 Ci/TJ-Nat per 300 gallons of solution There is no hazard from airborne material White Mesa Mill Date 2/07 Revision DUSA-l Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 20 of 43 If transportation accident occurred Which resulted in the loss of the tank content the material released would not constitute regulatory notification as defined in 40 CER 302 or 49 CFR 171 In the event of fire the solution would tend to extinguish it The type of accident that must be considered is rupture of the vessel wall and the resultant need to contain the spillage The driver carries with the truck an emergency kit which contains respirators clothing hammer knife tent pegs and 1000 square feet of plastic sheeting In the event of an accidnt he is instructed to do the following Place the plastic sheeting under the leak If the leak is small try to repair it with the aluminum tape If the leak cannot be contained by the above procedure the foam pack will be used to build dike over the plastic sheet which is dropped on the ground 6.10 Decontamination This section established the criteria and procedures for personnel ground area and equipment decontamination Prompt decontamination is essential to avoid possible internal exposure to radioactive material 6.10.1 Criteria Criteria presented is based on radioactive contamination resulting from an accident involving natural uranium yellowcake and is excerpted from the U.S Nuclear Regulatory Commission NRC guidelines where appropriate Personnel and Clothing Personal clothing skin and hair must not have any detectable alpha contamination as measured with the Ludlum Model or equivalent incorporating the alpha scintillation detector probe Land Areas and Equipment The following instructions apply in all cases reasonable effort must be made to completely eliminate residual contamination White Mesa Mill Date 2/07 Revision DUSk-I Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 21 of 43 Radioactivity on equipment or surfaces shall not be covered by paint plating or other covering material unless contamination levels as determined by survey and documented are below the limits specified below prior to applying the covering reasonable effort must be made to minimize the contamination prior to use of any covering Prior to release of equipment or abandoning the accident site comprehensive survey will be made and recorded to establish that contamination is within the limits specified below Acceptable Surface Contamination Fixed Average Maximum Removable 5000 dpmIlOO cm2 15000 dpmIlOO cm2 1000 dpmIlOO cm2 0.2mRad/hr@ 1cm 1.OmRad/hr@ 1cm Background mR/hr Background mR/hr Alpha measurements will be made using the Ludlum alpha scintillation probe Multiplying observed cpm by efficiency to obtain dpm and multiplying dpm by two to convert the probe area to 100 cm2 Removable contamination will be determined from dry swipe sample if the total surface area swiped is less than 100 cm2 pertinent levels must be reduced proportionally Measurements of average contamination should not include more than one square meter The maximum contamination level applies to an area of not more than 100 cm2 The acceptable mRad/hr will be measured with the Texas Nuclear Ionization Chamber open window or equivalent Background mR/hr gamma is measured with the Ludlum Model or equivalent incorporating the gamma scintillation detector probe and determined in an area at least 200 feet away from the spill boundary for decontamination comparison White Mesa Mill Date 2/07 Revision DUSA-l Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 22 of 43 6.10.2 Personnel and Clothing Following are general guides for field use harsher methods may be used under direction of Health Physicist or Physician All contaminated clothing should be decontaminated by applying tape to the contaminated area in an attempt to transfer the material to the tape or by vacuuming Contaminated clothing which cannot be decontaminated should be removed and placed in plastic bags for future laundering thorough washing with soap and water is the best general method of decontaminating the fce hands hair and body The water should be used only one time soft bristled brush or nail brush may be used however care should exercise not to irritate or abrade the skin In addition care must be taken to prevent decontamination solutions from entering the body openings or cuts Several washings and rinsings may be necessary to achieve an acceptable decontamination level To prevent chapping lanolin or hand cream may be applied to areas which have been washed or scrubbed several times In many cases tenacious surface-absorbed contamination may be removed from hands and/or forearms by promoting sweating in rubber gloves sealed at the cuff between washings Ii When contamination of person is detected nose swipes and urine samples should be collected Section 6.8 Ground Areas The bulk spilled yellowcake will be shoveled into lined metal drum and residual material will be vacuumed Always clean the area ahead of you making certain to stand in contamination free spot while working Dusting during decontamination will be controlled by use of the water spraying unit do not use excessive water If the spill is contained under plastic cover remove the cover in one-foot increments as decontamination is accomplished The initial decontamination can be accomplished visually by color yellow observation followed by survey with Geiger counter and finally by alpha monitoring and monitoring with the TN Model 2590 equipment or equivalent White Mesa Mill Date 2/07 Revision DUSA-l Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 23 of 43 Equipment Field decontamination is limited in most instances to the removal of radioactive contamination that is loosely attached in grease dirt or mud Contamination that is impacted ground-in or caught up in rust demands more abrasive measures and fairly sophisticated techniques often not available if the field Basic field guidelines are plastic sheet or other drop cloth should be spread on the floor or ground to catch any loose contaminantprior to commencement of decontamination operations Dry items may be vacuumed ththoughly incorporating scraping or Wire brushing to loosen surface material Items may be wet wiped using rags or they may be sloshed in or sprayed with water to remove loose contamination provided the items will not be damaged or impaired by moisture Acetone dampened rags may be used to remove more tenacious surface-bound contamination Failing the above sandpaper or steel wool may be used to remove thin layer of the surface material followed by vacuuming or damp Wiping Rags used for cleaning should be infolded and changed often to avoid spreading the contamination Used rags are placed in plastic bags If all above fails and after thorough documentation of circumstances and contamination levels the contaminant may be released from the accident site with prior govemment agency approval

EMERGENCY RESPONSE White Mesa Mill Date 2/07 Revision DUSA-I Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 25 of 43 INTRODUCTION This Appendix outlines personnel training requirements to ensure emerency preparedness in the event of transportation accident involving natural uranium yellowcake The training consists of classroom discussion and demonstration as Well as practical field exercise SESSION CLASSROOM DISCUSSION AND DEMONSTRATION General Information Natural uranium yellowcake decays through compl scheme that results in emanation of alpha beta and gamma radiation The amount of radiation associated With specific volume of yellowcake is very low when compared to other natural radioactive materials such as radium therefore small amounts of spilled yellowcalce are relatively difficult to measure With portable instrumentation In practical application the beta/gamma radiation associated with small quantities of yellowcake can be detected more readily than alpha or gamma only although alpha is more abundant it does not travel significant distance in air and it is easily shielded making field measurements very time consuming and impractical for an emergency situation Therefore beta-gamma monitoring with portable Geiger Mueller GM detector is the primary survey instrument used Biological Hazards The primary hazard associated with yellowcake is the effect of alpha radiation Since alpha is relatively large particle it cannot penetrate the skin and must be inhaled or ingested to cause biological damage Because of the low specific activity associated with yellowcake it takes about 17 milligrams within the body to represent maximum permissible body burden as compared to 0.0002 milligrams of radium-226 required to produce the same effect Protective Clothing and Respirators This equipment is provided to prevent contamination of personal clothing and the body as well as to avoid transfer of contamination to locations outside the spill area The protective clothing and respirators are discussed in this section demonstration and practice included Coveralls Coveralls are provided to prevent particulate contamination from coming in contact with the skin or clothing White Mesa Mill Date 2/07 Revision DUSA-1 Book 4116 Transportation Accident Response Plan for Uranium Concentrate Spill Page 26 of 43 Coveralls are donned in the normal dressing manner directly over personal clothing All openings front pockets collar and leg and sleeve cuffs are sealed with tape before entering the spill area When exiting the spill area coveralls are removed as follows All tape is removed The front of the coveralls is pulled open and Coveralls are removed by pulling them off the shoulders and off the trunk and legs by turning legs inside out as the garment is removed Used coveralls are placed in plastic bag Shoe Covers These are used to prevent liquid or particulate contamination from coming in direct contact with the wearers shoes and to avoid tracking contamination outside the spill area They are pulled on over the wearers shoes and removed by grasping the top edge and pulling downward which results in turning the shoe cover inside out Used shoe covers are placed inside plastic bag Head Covers These are used to prevent contamination from coming in direct contact with the hair ears head and neck The head cover is placed directly on the head underneath other head wear hard hats if required Head covers are removed by opening the front snaps grasping the top and pulling off toward the back of the head Used head covers are placed in plastic bag Gloves Gloves are used to prevent contamination of hands from radioactive particulates and to protect the hands from corrosive materials When exiting the contaminated spill area or after handling contaminated material the glove is removed by grasping it by the cuff and pulling downward off the hand this results in turning the glove inside out Used gloves are then placed inside plastic bag Respirators Demonstration and Practice Respirators full are provided to prevent inhalation of particulate material which may become air-borne during spill containment or decontamination operations Prior to.use the mask shall be checked as follows Cleanliness of mask facepiece valves and eyepiece is visually checked The head harness is checked to assure all straps and fasteners are functional White Mesa Mill Date 2/07 Revision DUSA-1 Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 27 of 43 The canister is examined to assure free flow of air and tightness of connections The integrity of the facepiece is visually checked by flexing the unit inside out and observing any cracks or holes Respirators are donned by placing the chin in first then pulling the head harness or straps over the head and tightening the Straps To avoid contamination transfer when disrobing protective clothing shall be removed in the following sequence Remove glasses Remove head cover Remove coveralls Remove respirator and Remove shoe covers Disrobing will take place at the RADEX area control point Radiation Monitoring and Sampling Various portable radiation detection instruments are radiation sampling devices are provided to assist in identifying the boundaries of the spill area detennining radiation exposure rates documenting contamination levels and determining if internal personnel exposures have resulted Since yellowcake has very distinctive color response team members should incorporate visual observation With radiation monitoring and sampling to asses contamination extent This section discusses types of equipment provided and application of each demonstration and practice included Beta-Gamma Monitoring The Geiger Counters and Ludlum Model with the Model 44-6 thin wall GM tube detector are used for beta monitoring or equivalent These instruments measure most of the beta and some about ten percent gamma radiation This is the primary tool used for monitoring ground areas and equipment associated with spill Basic steps are as follows Turn the instrument on and check the batteries Turn the scale selector switch to the appropriate scale White Mesa Mill Date 2/07 Revision DUSA-I Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 28 of 43 Move the detector shield to the open window position Place the U-238 check source on flat clean surface Grasp the detector probe with fingers in manna assuring not to cover the open window Place the detector probe open window grill in contact with the check source The meter should indicate cpm equal to about one-fifth 20 percent of the total dpm of the source Since measureipents are used for relative comparison with background radiation and not for accurate exposure or analytical measurements the object of this check is to ascertain instrument response to radiation source Monitor desired area by moving the open window detector slowly about one foot per second over the area about one-inch above the surface Gamma Monitoring The Ludlum Model with the Model 44-2 gamma scintillation detector probe or equivalent is used for these measurements Gamma measurements are not normally required in conjunction with yellowcake spill however they can be used to supplement monitoring normally accomplished with Geiger counter in the event Geiger counters are not available or operable The instrument operational checks and subsequent monitoring are performed in the same manner as those discussed for beta except the Cs-137 check source is used and the detector probe does not have an open window the lower one inch of the probe is the sensitive portion Alpha Monitoring The Ludlum Model with the Model 43-5 alpha scintillation probe or equivalent is used to make alpha measurements as follows Turn the instrument on and push the BAT button to assure batteries are in good condition Place the Th-230 check source on flat clean surface Grasp the detector probe in the palm of the hand extending thumb and fingers about 0.5 cm below the detector window to avoid damaging the mylar when monitoring rough surfaces Turn the range selector switch to the appropriate position and center the White Mesa Mill Date 2/07 Revision DUSA-l Book 1116 Transportation Accident Response Plan for Uranium Concentrate Spill Page 29 of 43 detector probe over the check source The meter should indicate counts per minute cpm equal to about 20 percent of the total dis integrations per minute dpm of the source the decimal equivalent of this percentage is called the efficiency factor Counts per minute are converted to dpm through dividing them by the efficiency factor Move the detector probe to surface requiring monitoring and hold in one place until meter reaches its maximum deflection Since the detector probe covers about 50/cm2 it is necessary to multiply measured dpm by to obtain dpmIlOO cm2 for criteria comparison Continue process in above until entire surface is monitored Swipe Samples Surface swipes are used to identify the presence of loose or removable contamination on the areas or items of interest for comparison with acceptable surface contamination levels Swipes are spot checks for the presence or spread of contamination but they do not provide quantitative reproducible data which can be used to document contamination levels Therefore swipe samples and analysis results are treated more informally than direct instrument measurements obtained from the surface of concern The person collecting swipe samples must wear gloves surface area of approximately 100 cm2 is wiped with dry Whatman filter paper to collect any larger contaminated particles The filter paper is dampened with acetone to wipe surfaces for collection of very fine particles Swipes are monitored with the alpha scintillation detector and resulting data is converted to dpm/100 cm2 After monitoring the swipe is placed in an envelope using tweezers to avoid scraping material off the swipe the envelope is sealed with tape and the sampling location and date of collection is recorded on the tape Nose swipes consisting of tips are collected from all persons working in or otherwise exposed to the yellowcake spill Collection is accomplished by extending the cotton tip into each nostril and gently swirling it These swipes are monitored and handled in the same manner as other surface swipes Air Sampling High-volume air samplers are used to monitor presence of airborne radioactivity One unit is located about 50 feet upwind from the yellowcake spill and another is located about 50 feet downwind from the spill as follows White Mesa Mill Date 2/07 Revision DUSA- Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 30 of 43 Locate air sampler at least three feet above the ground in an area with no obstructions between the source spill and the sampler Connect extension cords between samplers and tile portable generator Make certain filters are securely in place on the air sampler head Turn the air sampler on and record the date start time sampler flow rate and location At the end of the sampling period normlly 24 hours record the sampler flow rate time of day and date and secure the sampler Remove the sample filter and place in plastic Petri-dish using care to assure particles are not removed from the filter Mark the filter Petri-dish with pertinent data and above and commence another sampling period through above Contamination Control This section combines individual subjects covered in

vehicle Vehicle may or may not be damaged Caution people not to tamper with the containers Use civil authorities to help you if necessary It is not necessary to have specific distance between humans and the containers or truck but for ease of controlling the situation ask people to stay back 10 to 15 feet White Mesa Mill Date 2/07 Revision DUSA-1 Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 42 of 43 If closed containers are lying on the road obtain assistance from whatever civil authority is available to move containers to the side of the road Assure local authorities that there is no danger in handling closed containers CONTAINERS ARE LEAKING OR DAMAGED TOO SERIOUSLY to be moved Truck or railroad car may or may not be damaged Caution people to stay away from the material Keep them at distance of at least 25 feet Extreme distance is not necessary Use civil authorities to help if necessary Assure local authorities that there is no danger from radIation but that people should avoid breathing any dust from the material Avoid trackage of material by people or vehicle Obtain help from local civil authorities if necessary to reroute traffic around the spill area Keep material from running into streets gutters sewers etc if possible simple method for doing this might be to dig trench around the material or throw up an earthen dike several inches high If required cover the spilled uranium concentrate The vehicles emergency kit contains four approved dust respirators respirator user instructions 1000 square feet of plastic sheeting tent stakes nails hammer and knife Don respirator and cover the spilled material with the plastic sheeting and secure the edges of the plastic to the ground using tent stakes or to the bed of the truck with nails Undamaged containers can be moved to the side of the road Avoid breathing dust from the material When covering the material obtain simple respirator if possible If none is available work the material in such manner as not to stir up excessive dust FIRE involving vehicle or in immediate vicinity of vehicle Isolate the vehicle from other people and property if possible Use civil authorities for help Obtain fire fighting help from local group The material you are hauling will not burn White Mesa Mill Date 2/07 Revision DUSA-l Book 16 Transportation Accident Response Plan for Uranium Concentrate Spill Page 43 of 43 Keep fire away from uranium containers if possible Use respirator if necessary to avoid breathing smoke from any fire involving your cargo because of the possibility of airborne particles if the drums are ruptured Do not spray water into open or leaking containers There is no reaction with water but heavy stream of water will spread the material and
