[en] The purpose of the Functional Design Criteria is to provide technical direction for the development of detailed design criteria for the exploratory shaft facility. This will assure that the completed exploratory shaft facility design is in accordance with the ONWI mission as well as the National Waste Terminal Storage program directives. The functional design criteria are not intended to limit or constrain the designer's flexibility to design. However, the following design philosophies will be incorporated in the designs: The exploratory shaft will be designed to fulfill its intended purpose and mission. Sound engineering principles and practices will be consistently applied. The health and safety of the public and the workers will be an essential factor in the design. The exploratory shaft will be designed to achieve economy in its construction, operation, and maintenance. All applicable federal, state, and local laws and regulations, as well as all applicable national consensus codes and standards, will be satisfied. The adverse impact to the environment will be minimized
