Phase 1 - Rank residual risks to human health and to the ecosystem, explore potential economic impacts, and delineate relevant quality of life issues
Phase 2 - Hold community meetings to gain input from Hawaii's residents as to their environmental priorities and to provide information on the results of Phase 1
Phase 3 - Develop a strategic plan, using the results from Phase 1 and Phase 2, to prioritize the State's allocation of human and financial resources for environmental programs

The ranking took place during Phase 1. Both of the rankings (Risks to Public Health and Risks to Ecosystems) were based on quantitative scoring systems, relying primarily on scientific risk assessment methodologies and secondarily on expert technical estimations.

Representatives from the all of the above stakeholders groups were involved at some point during the public health and ecosystem components of Phase 1. The General Public were not significantly involved until Phase 2.
