Regulator participation is important for the successful deployment of a Triad approach. There are three key areas where regulatory participation/involvement goes beyond what typically is required under a more traditional approach. The first is conceptual site model development and review. The second is selection and vetting of dynamic work strategies, along with supporting real-time measurement systems. The third is involvement with decisions during work activities on an as-needed basis. The use of a Triad core team to support decision-making can be one effective means for securing regulatory participation. The requirements for a successful team are that members are committed to working through issues in a non-adversarial manner, that they are available to make timely decisions, that they are in it "for the long haul," and that they can speak with confidence for their respective agencies. The need for unforeseen decision-making on-the-fly should be minimized for dynamic work strategies and accompanying plans that are comprehensive in their contingency planning. When decisions need to be made during field activities, effective information organization, presentation, and dissemination capabilities can be essential to timely decision-making. The use of secure project support Web sites is an effective means for presenting and disseminating real-time data to core team members who may be physically dispersed.
