Baseline Plan - the current regulation plan, 1958D with simulated deviations (1958DD), is the baseline plan against which all other plans were measured.
Candidate Plans - options chosen by the Study Board to be presented with a full evaluation to the IJC.
NOTE: Plans A+, B+, and D+ are modified versions of Plans A, B, and D presented at the public meetings in the summer of 2005. Background on the original evaluation of Plans A, B, and D is provided in the summer candidate plan handout. A brief description of how the plans have been modified and the impact on the evaluation is provided in a brief comparison reportprepared by the Study Board.
Reference Plans - contain unique characteristics that warrant comparison to the baseline plan but were not considered valid options by the Study Board for recommendation to the IJC.
Interest Specific Plans - developed with a focus on a particular interest and generally resulted in disproportionate harm to other interests. They were not recommended by the Study Board as options plans for the IJC to consider.
