## Document text

(a) When a customer requests transportation service, a utility shall provide the
customer requesting transportation with the utility's gas transportation form. This
form shall set out clearly the information necessary for the utility to determine
whether it can provide the requested transportation.

(b) In determining whether capacity is available to provide the requested
transportation, a utility shall take into account all conventional methods of
delivering gas through its system, including without limitation forward haul,
compression, exchange, flow reversal, backhaul, and displacement. The utility is
not required to perform exchanges or displacements over segments of its system
which are not physically connected.
(c) A utility shall process, shall approve or reject, and shall provide notification of its
decision with respect to a transportation request within 60 days after receiving a
written request from a transportation customer. If the utility rejects the request,
the utility shall provide, within three business days, written notice of its decision
to the customer and shall retain a record of the rejection notice for two years. The
notice shall detail the reasons for the rejection and shall explain what changes
are necessary to make the request acceptable. If the request is approved, the
utility shall provide, within three business days, written notification of approval to
the customer.
(d) A utility shall maintain on file with the Commission a standard gas transportation
agreement. All gas transportation agreements shall contain the following
provisions.
(I) This agreement, and all its rates, terms and conditions as set out in this
agreement and as set out in the tariff provisions which are incorporated
into this agreement by reference, shall at all times be subject to
modification by order of the Commission upon notice and hearing and a
finding of good cause therefore. In the event that any party to this
agreement requests the Commission to take any action which could cause
a modification in the conditions of this agreement, the party shall provide
written notice to the other parties at the time of filing the request with the
Commission.
(II) If the end-use customer uses a marketing broker for nomination, gas
purchases, and balancing, the end-use customer shall provide the utility
with an agency agreement.
(e) A utility shall maintain on file with the Commission the standard agency
agreement to be used when an end-use transportation customer uses a third
party for any services related to nomination, gas purchases, and balancing
activities.

(f) A utility shall maintain logs showing all requests for gas transportation. The log
shall contain the following information: the identity of the party making the
transportation request, the date of the request, the volume requirements,
duration, receipt and delivery points, type of service, and the disposition of the
request. The utility shall retain these logs for two years.
