From page 28...
... The next section will help you determine the consequence value for each scenario in the hazardous materials portfolio. The method of assessing consequences should be consistent with the capability of the emergency response planner or planning team.

... In practice, simply measuring the number of people exposed to a hazardous material is often used as a proxy for fatalities and injuries. Determining the affected area is dependent on the type of material involved, its hazards, and how that material behaves when released from its containment or packaging.

... Step 10 Determine the affected area for population impacts from a potential release for each scenario in the hazardous materials portfolio. As shown in Figure 2, the affected area is the protective action distance or hazard distance squared.

... Appendix C provides additional approaches for obtaining more detailed estimates of environmental exposure areas. Step 12 Determine the affected area for environmental impacts from a potential release for each scenario in the hazardous materials portfolio using the same methods used to estimate the affected area for population impacts.

... Selecting the Consequence Value Again, the mitigating effects of emergency response coverage are not considered when determining these potential consequences. Comparing the potential population exposure and the environmental costs measured in economic terms to the values in Table 13 provides the appropriate consequence value to use.
