[en] The concepts of exemption and clearance have a lot of advantages in the aspects of effective use of limited resources, land, and optimization of regulatory works. The exact scopes and extent of the implementation of the concepts, however, can widely vary depending upon each country's own specific situations. In order to support the political decision-making on the practical implementation, a series of possible alternatives, general methodology for decision-making, and factors to be considered were proposed. Five primary categories and subsequent nineteen secondary categories were suggested and discussed, and four-step-approach was introduced in order to show the general guidelines for establishing an appropriate national regulatory framework. Though the specific procedure for each country to get to the practical implementation of the exemption and clearance concepts was not described, it is anticipated that the basic guidelines proposed in this paper can be used as a general reference.
