unauthorized daily overrun taken by Shipper at such Delivery
Point. Transporter will waive this penalty on a basis which
is not unduly discriminatory if, in the exercise of its
reasonable discretion, Transporter determines that such
action by Shipper did not cause operational difficulties or
affect the integrity of Transporter's system or Transporter's
ability to render scheduled service on such day.
6.4 Predetermined Allocation Method.
(a) Transporter may negotiate and enter into OBAs
with interstate pipelines, intrastate pipelines and other
entities. Transporter will not utilize pre-determined
allocations ("PDA") if Transporter has an OBA in effect for a
point. No difference balanced in-kind shall be allocated to any
Shipper at the Receipt or Delivery Points covered by the OBA.
PDA elements should be standardized. Only one PDA allocation
methodology should be applied per allocation period.
(b) As used in this Section 4, a PDA is an
agreement by or among point operators, prior to the beginning of
the gas day, at a Receipt or Delivery Point to allocate the
difference between the scheduled daily quantity and the actual
daily flow of gas in a mutually agreeable manner. Types of
allocation methods include, but are not limited to, ranked, pro
rata, percentage and swing. PDAs shall be provided by the
interconnecting operator, and for multi-tiered allocations, may
be provided by the upstream title holders or Shippers.
Interconnecting operators at Receipt Points shall provide a PDA
to allocate to upstream title holders. Upstream title holders
may provide a PDA to allocate to the parties taking possession of
their gas at a Receipt Points. Shippers may provide a PDA to
allocate to their nominations at either Receipt or Delivery
Points. Two welded parties should agree on who submits a PDA
methodology and who allocates at the point before gas flows. The
upstream or downstream party providing the point confirmation
should submit the pre-determined allocation to the allocating
party after or during confirmation and before start of gas day.
The allocating party should send back "confirmation" of receipt
of the pre-determined allocation within 15 minutes.
(c) If confirming parties cannot agree upon an
allocation methodology, "pro rata based upon confirmed
nominations" shall be used as the default method.
