ESRI Shapefile for USA showing up in Norway

I have a shapefile that contains pipeline corrosion data and location data from our ESRI mapping system.  Regardless of what I try the data that should be shown as being in Pennsylvania, USA is showing up in Svalbard, Norway.  I have tried other shapefiles as well and the map that is produced is always half-way around the world.  Any thoughts?
