This learning module, which is part of a management and supervisor training program for managers and supervisors employed at the Department of Energy's Waste Isolation Division, is designed to enable trainees to identify regulatory organizations and oversight groups and monitor and provide guidance in the implementation of the requirements of applicable codes, orders, and standards. The first section is an overview of the module. The next nine sections describe the origin, structure, function, and regulatory documents of the following regulatory agencies and oversight groups/advisory committees: Department of Energy; Occupational Safety and Health Administration; Environmental Protection Agency; Department of Transportation; Nuclear Regulatory Commission; New Mexico Environment Department; Mine Safety and Health Administration; Environmental Evaluation Group; and Defense Nuclear Facilities Safety Board. Each section also includes enabling objectives and an employee-manager scenario that is designed to illustrate effective management practices and practices to avoid when dealing with a regulatory agency or oversight body. Concluding the module are a list of actions that can be taken to make a section/plant more effective, 20-item reference list, practice test, and test answers. (MN)
