Express Pipeline abruptly withdraws its application to abandon leaky oil pipeline in place

In a previous post, I reported on an application by Express Pipeline (Kinder Morgan Canada) to abandon a leaky oil pipeline in place.  Express intended to ask the NEB to allow it to build a new pipeline adjacent to the old one.  Yesterday, Express wrote to the NEB to withdraw its abandonment application without giving any reasons: November 8, 2010 Withdrawal Letter.
