The owner companies place costs above safety.  The Valdez Marine Terminal has 14 miles of cable trays.  The cables installed during the original build did not have equipment grounding conductors.  Unbelievable as it sounds this is true.  How this facility has gone so many years without a major fire and/or explosion is a miracle.  But the oil companies are not going to let anyone make them repair this anomaly.  They got rid of the Fairbanks State Electrical Inspector that demanded a quality repair in 1996 and kept the slot open for 10 years.  After the slot was reinstated by the legislature all electrical inspections of the pump stations, North Slope, and the Valdez Marine Terminal was turned over to a controlled in house electrical inspector that works for the Joint Pipeline Office.  Don't ever kid yourselves, Big Oil controls their quality control.  It is the fox guarding the chicken house!
