What is a curtailment?
              
                A curtailment is the reduction of gas deliveries due to a
                shortage of supply or because demand for service exceeds a
                pipeline's capacity. Usually there is a hierarchy of customers,
                in which some may be required to partially or totally cut back
                takes of gas before others. Industrial users, for example, are
                usually curtailed before service to residential users is
                reduced.
              
              
                For our customers who choose interruptible transportation,
                Dominion Energy Gas Marketing issues a curtailment order when
                service has to be interrupted. This means energy reserves have
                dropped or are expected to drop below a certain level. The
                curtailment order signals that rotating outages are going to
                occur.
              
              
                Most customers with alternative fuel sources (#2 oil, #6 oil,
                waste oil, coal and others) choose interruptible service for the
                majority of their energy load. However, customers agreeing to
                interruptible service must comply with curtailment orders or pay
                noncompliance fees.
              
              
                Interruptible customers are curtailed in order of priority to
                ensure firm deliveries are met. Residential customers, small
                general service rate customers and other end users holding firm
                transportation contracts will not be curtailed.
