the mean and median are essentially the same from that study. The DOE

Eastern United States sites that have updated site specific probabilistic seismic

hazard results have had to address the LLNL and EPRI uncertainty issues as

well. At present, assessments have been completed inconsistently from site to

site. The use of the Standard will provide a consistent approach to clarify these

uncertainties.

The discussion provided below is organized as follows: Because there is

extensive discussion and evaluation of the existing seismic hazard curves, the

seismic hazard position is provided first. The text which follows reviews the

existing probabilistic seismic hazard curves, and provides the basis for the

development of the specific factors selected for the seismic hazard position.
