Abstract: This paper describes the activities undertaken to examine relevant factors and select the initial access for the Yucca Mountain exploratory studies facility. To aid their decision, the task group used a figure of merit evaluation to examine preference for either the north or south site. Based on the evaluation of the programmatic concerns identified, it was recommended that if the DOE elects to proceed with a phased approach to the development of the Exploratory Studies Facility, the initial access constructed should be the North Ramp. This recommendation was strongly influenced by the need for environmental baseline monitoring and current configurations, especially the location of the Core Test Facility. Construction of the North Ramp portal pad was started on November 30, 1992.
