Final Program - Society for Risk Analysis

organizations, sectors, and the Nation. As the cybersecurity discipline has become akey focal point of national and homeland security discussions, CIKR sector entitiesand governments at all levels have increased their demand for understanding cyberrisks. In response, the National Cyber Security Division has leveraged its uniquepublic-private sector partnership role as a mechanism for establishing approaches tohighlight national-level cybersecurity risks and concerns. The presentation will definecyber infrastructure, describe a top-down, functions-based approach to risk management,explain why this approach is best suited for the virtual and distributed natureof cyber infrastructure, and explain why organizational risk management approachesare needed to inform a national-level approach to cybersecurity risk management.The presentation will draw upon recent national-level risk management efforts includingthe National Infrastructure Protection Plan (NIPP) implementation and theInformation Technology Sector Baseline Risk Assessment. It will also describe theCybersecurity Assessment and Risk Management Approach (CARMA), which is anational-level approach to cyber risk management that can initiate sector, sub-sector,regional, or State and local strategic cyber risk management efforts. CARMA consistsof five stages and can integrate into established cyber risk management frameworksor be used as a foundation for a broader risk management framework. The processesand outputs specific to each stage can be used to scope, identify, and address cyberrisk at the national-, sector-, or enterprise-level.M2-D.1 Oliver G, Tardif C*, Provencher M; michele.provencher@tc.gc.caTransport CanadaRISK MANAGEMENT: THE HEART OF THE TRANSPORT DANGER-OUS GOODS PROGRAMEach year, products identified as dangerous goods are transported across Canadaby road, rail, water and air. Shipments of dangerous goods range from industrialchemicals to manufactured goods and, while indispensable to our modern way of life,can pose a threat to life, property and the environment if not handled safely. TheTransport Dangerous Goods Directorate’s legislated mandate is to promote publicsafety in the transportation of dangerous goods, and its activities reflect the requirementsof the Transportation of Dangerous Goods Act, 1992. The Transportation ofDangerous Goods Regulations, adopted by all provinces and territories, establish thesafety requirements for the transportation of dangerous goods. Federal and provinciallegislation provide for the regulation of an extensive list of products, substancesor organisms classified as dangerous. This presentation provides an overview of riskmanagement at the Transport Dangerous Goods (TDG) Directorate of TransportCanada. The organization, its activities, its approach to risk and future challenges arediscussed. The quantities of dangerous goods freight transported in Canada and thenumber of dangerous goods accidents to be reported under the TDG Regulationsare presented to give an overall perspective. A few risk analyses are also mentioned.152Risk management and the underlying risk analyses bring the knowledge to developpolicies, regulations and standards and leads to the continuous improvement of theTransportation of Dangerous Goods program and therefore public safety.P.30 Ono K, Toyoda T, Shimada S, Nezu T; kyoko.ono@aist.go.jpNational Institute of Advanced Industrial Science and TechnologyEXPOSURE ASSESSMENT FOR AMBIENT HEXAVALENT CHROMI-UM (CR(VI)) IN JAPANESE INDUSTRIAL AREAAirborne hexavalent chromium (Cr(VI)) is a known human respiratory carcinogen.Cr(VI) inhalation risk for the general population has been of great concern andits characterization is important. The goal of this study is to assess the risk of ambientCr(VI) for general population and identify the mass of high risk sub-population(s).The authors improved and evaluated Cr(VI) sampling and analysis procedures, andmeasured ambient Cr(VI) in Japanese industrial area. A low-volume air sampler wasused for sampling with an alkaline (potassium hydrogen carbonate)-treated hydrophobicpolytetrafluoroethylene (PTFE) filter, that was designed to prevent Cr(VI) reduction.Field spike-recovery tests typically demonstrated over 80 % recovery of Cr(VI)and no inter-conversion of valence (reduction to trivalent chromium) occurred. Thelimit of detection (LOD) was 0.02 - 0.1 ng per cubic meter, which corresponds to0.4- 2 ng per filter, by this method. This LOD is lower than U.S. EPA’s 10^-5 risk level,which is corresponding to 0.83 ng per cubic meter. The ambient air sampling wasconducted in the spring and autumn of 2009, at industrial area of Tokyo metropolitanwhere some dozen of small chromium plating factories in operation. Populationdensity of the area was eleven thousand persons per square kilometer. The Cr(VI)concentration was up to 0.4 ng per cubic meter, which was less than 10^-5 risk level.Next, ambient Cr(VI) concentration in that area was estimated by an atmosphericdispersion model. Cr(VI) emission factors were characterized on electroplating (hardchromium and decorative chromium) factories and municipal solid waste incinerators.Estimated Cr(VI) concentration was less than 0.1 ng per cubic meter. The estimatedresults were consistent with measured concentration.M2-D.2 Orosz MD, Southwell C, Chen J, Maya I, Chatterjee S, Salazar D, SouthersE; mdorosz@isi.eduUniversity of Southern CaliforniaA PORT SECURITY RISK ANALYSIS AND RESOURCE ALLOCATIONSYSTEM - FROM TACTICAL TO STRATEGICSeaports, airports, and other transportation nodal points face many challenges -including maximizing operational efficiency, minimizing risk from terrorism or otherman-made and natural disaster events and minimizing impacts to the environment.Often these challenges are at odds with one another - increasing one often comes atthe expense of achieving others. For example, in a seaport environment, increasingport security by adding additional container inspection stations often causes a
