[1] The 2012 outages reported in this table resulted from incidents on transmission assets or other (upstream) facilities that are not part of Vector’s gas transmission system, but, due to the interconnected and interdependent nature of the transmission system, resulted in interruptions to customers served by the Vector gas transmission system. In each case curtailment of service to customers has been at the direction of the Critical Contingency Operator.
