Federal law requires pipelines, like the Keystone, to be regularly inspected to spot corrosion, failing welds, minor leaks, and other such issues before they can cause any problems. To do this, oil companies send PIGs — Pipeline Inspection Gauges — through their pipes. However, the data they send back is only as good as the computer code used to analyze it, and three whistleblowers have told us that the software has deliberately been calibrated so the PIG doesn’t squeal.
The PIGs are honest, but the software isn’t. They’ve essentially muzzled the PIGs by making the diagnostic software less sensitive than required by government regulations. “It feeds them incorrect information about the state of their pipeline,” says one of our whistleblowers in our exclusive report, first broadcast today on The Thom Hartmann Program  (see video  above).
[Note: This information has been corroborated by two other whistleblowers, who were too scared to go on camera for fear of reprisals — even with their faces in shadow and their voices disguised!]
“In the worst example,” our whistleblower tells us, “you could have a pipeline that has corrosion that goes into an urban area where there are many people that explodes.”
And that’s exactly what happened in 2010 in Northern California, when the San Bruno pipeline exploded , killing eight people.
