"If it ain't broke, don't fix it!"
Someone at Con Edison will now work up a Excel spreadsheet on the cost benefit analysis of checking and replacing 105 miles of pipe vs. paying for sporadic death, injury and damage. While the pipe in question was 83 years old, some of the pipe is over 100 years old. The last pipe explosion was at Gramercy Park on 1989 with 3 people killed. You do the math.
