Default assessment endpoints and indicator species have been identified on a regional basis throughout Alaska, and guidelines have been developed for their application to site-specific ecological risk assessments (ERAs). Default assessment endpoints and indicator species were selected for each of ten regions based on ecological considerations and societal relevance (e.g., ceremonial, recreational, economic, or subsistence values). Stakeholder participation was a key element of the project. Representatives from the state of Alaska, the Environmental Protection Agency Region 10, the National Oceanic and Atmospheric Administration, U.S. Fish and Wildlife Service, industry, Alaska native groups, the military, recreational and commercial associations, and environmental protection groups provided input on risk management objectives, technical issues, societal values, or cultural concerns. Some participants also served in a peer-review capacity. The guidance resulting from this project will increase consistency in risk management decisions in Alaska (which are often driven by the results of ERAs), will allow incorporation of stakeholder concerns even at smaller contaminated sites where their involvement is often minimal, and will also reduce time in preparation of ERAs by responsible parties and in their review by agencies. The approach taken by the state of Alaska provides a model that could be applied in other states, regions, or countries to streamline the ERA process.
