So if you, in the industry, had so much foresight 50 years ago, why is there only 1 Oil line and no Gas line from the slope?  All of the permits were in place, all of the manpower was in place, all of the infrastructure was in place and the costs for a high pressure Gas line designed "for the future" would have been much less.  Perhaps 50 years ago you were a roust-a-bout just out of high school in Valdez?  

Get real, The Inlet infrastructure is almost 50 years old and the actual location of the recent gas leak has a different bottom structure than that proposed under the current plan.
