Probability of Future Occurrence Based on historical occurrences recorded by PHMSA, there have been 15 serious incidents of hazardous materials release in the 20-year period from 1999 through 2018. Using historical occurrences as an indication of future probability, there is a 75 percent annual probability of a serious incident occurring. Probability: 3 ā€“ Likely

Vulnerability Assessment People

People near facilities storing or transporting hazardous materials are at higher risk of exposure to a release incident. Additionally, any individuals working with or transporting hazardous materials are also at heightened risk. Depending on the materials, they may pose certain health hazards. If hazardous materials contaminate soils or water supply, people may be at risk of exposure through food or water. Property A radiological incident could cause severe damage to the power station itself but would not cause direct property damage outside the station. However, property values could drop substantially if a radiological incident resulted in contamination of nearby areas. Environment A radiological incident could result in the spread of radioactive material into the environment, which could contaminate water and food sources and harm animal and plant life. Consequence Analysis Table 4.91 summarizes the potential detrimental consequences of hazardous materials incident. Table 4.90 ā€“ Consequence Analysis ā€“ Hazardous Materials Incident




Contact with hazardous materials could cause serious illness or death. Those living and working closest to hazardous materials sites face the greatest risk of exposure. Exposure may also occur through contamination of food or water supplies. Responders face similar risks as the general public but a heightened potential for exposure to hazardous materials. A hazardous materials incident may cause temporary road closures or other localized impacts but is unlikely to affect continuity of operations. Some hazardous materials are flammable, explosive, and/or corrosive, which could result in structural damages to property. Impacts would be highly localized. Consequences depend on the type of material released. Possible ecological impacts include loss of wildlife, loss of habitat, and degradation of air and/or water quality. Clean up, remediation, and/or litigation costs may apply. Long-term economic damage is unlikely. A hazardous materials incident may affect public confidence if the environmental or health impacts are enduring.
