3.9 Imbalance Netting and Trading
(A) Operational Impact Area
An Operational Impact Area is the largest possible area on Transporter's system in which
imbalances have a similar operational effect and within which Shippers can net or trade
imbalances. On Transporter's system there is one (1) Operational Impact Area consisting of
the Western, Central, and Eastern rate zones. Shippers on Transporter's system may net or
trade imbalances within and across all three (3) rate zones.

(1) At the end of each Month, Transporter shall net all of a Shipper's imbalances within each
rate zone on and across its Service Agreements to provide the Shipper with the lowest

trading of imbalances with other Shippers. Transporter will first net imbalances among a
Shipper's Agreements under the same Rate Schedule and then will net imbalances across the
Shipper's Service Agreements under all Rate Schedules.
(2) In the event that Shipper desires to net imbalances across rate zones, Shipper shall be
subject to the applicable charges and fees for Transportation Service across the rate zones
only if any such charges and fees for the service have not already been paid. Any such
