Best prediction was achieved for integrated agency and NEPA goals with the models explaining approximately 54% of variance in the outcome for challenging projects and nearly 60% for simple
projects. For integrated agency and NEPA goals, perceptions that the process employed the best available biophysical science and had a clear and unambiguous purpose and need were paramount in both challenging and simple processes. Intra-team disagreement was associated with lesser achievement in challenging projects, while perceptions about theempowerment of the teamleader, the decision maker’s understanding of the NEPA process, the IDTLs’ belief in
substantive public involvement, and effective inter-agency engagement all contributed positively to the achievement of agency and NEPA goals.
