31. TRANSPORTATION, GATHERING AND STORAGE RETAINAGE ADJUSTMENT
31.1 General. Equitrans shall retain a quantity of gas received under
Rate Schedules NOFT, FTS, STS-1 and ITS to reimburse Equitrans for
fuel, loss, and unaccounted for gas required to provide
transportation service for Customers ("Transportation Retainage").
Equitrans shall retain an additional quantity of gas from those
Customers under Rate Schedules NOFT, FTS, STS-1, ITS and, where
applicable, Rate Schedule AGS, to reimburse Equitrans for fuel,
loss, and unaccounted for gas required to provide gathering
service to those Customers utilizing Equitrans' gathering
facilities ("Gathering Retainage"). Equitrans shall retain a
quantity of gas tendered for injection under Equitrans Rate
Schedules SS-3, 115SS, 60SS, INSS and LPS to reimburse Equitrans
for loss and unaccounted for gas required to provide storage
service for Customers ("Storage Loss Retainage"). The quantities
retained, which shall be separately stated as a Transportation
Retainage Factor, a Gathering Retainage Factor, and a Storage Loss
Retainage Factor, are on Statement of Retainage Factors of this
Tariff. (Sections 31.2 and 31.3 only apply to Equitrans Big Sandy
Pipeline retainage factors)
31.2 Determination of Big Sandy Pipeline retainage factors. Equitrans
shall commence the tracking of its experience under its Big Sandy
Pipeline transportation retainage factor as of March 1, 2008.
Equitrans shall adjust the Big Sandy Pipeline transportation
retainage factor on a semi-annual basis to take into account both
prospective changes in retention requirements and over-recovered
and under-recovered retainage quantities from the preceding period
as described in Section 31.3 below, with the first such adjustment
to be effective twelve (12) months following March 1, 2008.
Equitrans will file the Big Sandy Retainage Factor with the
Commission semi-annually on or before January 29 and on or before
July 31 to become effective March 1 and September 1, respectively.
31.3 Calculation of Big Sandy Pipeline transportation retainage factor.
In each filing, Equitrans shall calculate the Big Sandy Pipeline
transportation retainage factor using the following methodology:
(a) Equitrans will estimate the total quantity of gas in
dekatherms required for fuel and loss and unaccounted for
volumes, for transportation during the prospective 6 months
("prospective retainage quantities").
(b) Equitrans will separately adjust the prospective retainage
quantities for transportation upward or downward if and to
the extent that Equitrans under-recovered or over-recovered
retainage quantities during the prior 6 month period.
Equitrans will determine the existence and amount of such
under-recovery or over-recovery by determining the retainage
quantities received from Customers, during the prior 6 month
period and subtracting the actual usage of gas for fuel, loss
and unaccounted for during the period. The remaining over
recovered or under recovered quantity, if any, will be
subtracted from or added to the prospective retainage
(c) Equitrans will determine the adjusted transportation
retainage factors by dividing the adjusted retainage quantity
for transportation by the total throughput quantities
estimated to flow during the prospective 6 month period.
