The company behind the proposed Keystone XL oil pipeline, TransCanada, is facing new scrutiny at home. The Canadian broadcaster CBC News has revealed regulators buried a report about a rupture on a TransCanada natural gas pipeline in 2009. An investigation cited TransCanada for “inadequate” inspections and “ineffective” oversight. But for unknown reasons, the incident was never publicly disclosed and the report never released. The Canadian government has been a vocal proponent of TransCanada’s plans for the Keystone XL. Speaking to the CBC, environmental policy expert Nathan Lemphers said the report’s disappearance raises questions.

Nathan Lemphers: “It certainly seems fishy from the outside that this report was kept quiet due to an apparent administrative error. Certainly, if the report came out, it would have been — risen to immediate public attention.”
