## Document text

(a) Any reduction of gas purchases by a current sales customer who replaces sales
purchases with transportation directly reduces a utility's obligation to provide gas
to that customer on both a peak day and on an annual volume basis. If offered by
the utility, a customer may retain rights to gas supplies by electing to pay for
standby capacity service and standby supply service.
(b) Any reduction of gas purchases by a current interruptible sales customer who
replaces said purchases with transportation gas directly reduces the utility's
obligation to provide gas supplies to that customer on an annual volume basis. At
the discretion of the utility, a customer may retain rights to interruptible gas
supplies by electing to pay for standby supply service.
(c) If a sales customer converts all, or a portion, of its service to transportation and if
it does not elect standby supply service, then the customer must reapply for
sales service in the future if it wishes to convert the transportation portion of its
service back to sales service.
(d) The utility shall have no sales service obligation to a transportation customer who
is solely responsible for procuring its own gas supply. The customer may retain
rights to gas supplies by electing to pay for standby supply service.
