TransCanada, Pipeline Leaks, and Chernobyl

2007:

DNV estimated the chance of a leak from the Keystone Pipeline to be no more than once every seven to 11 years over the ENTIRE length of the pipeline in the U.S., depending on product and throughput. Using the most frequent seven year interval, this equates to a spill no more than once every 41 years at any location along the 220 miles of pipeline in South Dakota.

1986:

The odds of a meltdown are one in 10,000 years. [Vitali Skylarov, Minister of Power and Electrification in the Ukraine, two months before the Chernobyl accident.
