A conventional application of risk-assessment methods in this context might lead the proponent of the power plant to conduct analyses to determine whether the facility would contribute to exceedances of predefined risk thresholds -- for example, greater than a 10-6 risk from air toxics for the maximally exposed person, a violation of ambient air quality standards for criteria pollutants. Issues related to alternative sites would typically be addressed in a separate part of the analysis, with argument of why the selected site is preferable, and no formal evaluations of alternative technologies and their implications for costs or benefits would be considered.

A comprehensive consideration of options at the outset would ensure that all relevant stakeholders were present, avoiding NIMBY outcomes in which an alternative site is chosen in a community that has not been involved in the process. The risk assessments and economic, technical, and other analyses would be oriented around the proposed interventions and would allow for explicit consideration of the tradeoffs among different desirable attributes of the decision and upfront transparency about the solution set, methods, and criteria for decision-making.

A Case Study of Decision Support for Drinking-Water Systems Decision-makers and stakeholders seeking safe drinking water carry out their work in the face of a daunting array of microbial, chemical, climatic, operational, security and financial hazards. The capacity of risk assessment to support the societal goal of the provision of safe drinking water is an example of the critical need to reorient current risk-assessment practices away from the support of a series of disconnected single-hazard standard-setting processes and toward the provision of analytic support to facilitate the integration of complex health, ecologic, engineering, and economic elements of decision-making involved in providing safe drinking water.

A conventional application of risk-assessment methods might attempt to determine the allowable MeCl2 concentration in ambient air to meet a defined risk threshold. In this case, the risk assessment supports a distal decision to set a risk-specific concentration.
