This letter is a rebuttal to the Sept. 9 letter from Irene Moffet. There have been no issues with the pipeline in the ground, period. All incidents happened above ground, the oil was confined to our property and was cleaned up quickly. The average amount was five to 10 gallons — five gallons is three oil changes in a pickup. In The North Dakota incident, at 6:05 a.m. CDT, TransCanada's oil control center received a warning that something was occurring on the Keystone system at the Ludden pump station in Sargent County, approximately 40 miles southwest of Milnor, N.D.
After monitoring the situation for the next 21 minutes, we made the decision to shut the line at 6:26 and that process was started. Within nine minutes, TransCanada isolated the pump station by remotely closing the valves both up and downstream from the site. This demonstrated our safety system opened as expected.
The leak stemmed from a three-quarter inch fitting the diameter of a garden hose above ground at the pump station.
The safe and reliable operation of our infrastructure has been TransCanada's top priority for 60 years — this core commitment continues with the Keystone pipeline system.
