Standard approaches to defining and evaluating environmental risk tend to reflect technocratic rather than democratic values. One consequence is that institutional mechanisms for achieving citizen participation in risk decisions rarely are studied or evaluated.

It also defines democratic process criteria for assessing these and other participatory mechanisms.
