What Caused the MI NatGas Compressor Stn Fire in January?

You may recall MDN covering the story of the compressor station in Michigan that caught fire and exploded in January (see Michigan NatGas Compressor Station Catches Fire, Explodes). That single compressor (single point of failure, as it turns out) is responsible for pumping natgas to two-thirds of Michigan residents. After a two-month investigation, the station’s owner says it knows what happened, which can be summed up as a series of unfortunate events.
