CHARGES, AND CASHOUT

6.1 Subject to the remainder of this Section 6, on any Gas Day and at

that time when transportation nominations are due, Shipper may submit

an Access Request for balancing service under its IBS Agreement up to

its MDQ of park and/or loan.

A. The Access Request, which shall constitute Shipper's nomination

under the IBS Agreement, shall specify for a Gas Day the volume

and direction to park or loan as balancing services and must

reference the specific end user at a Delivery Point to which the

service relates. An Access Charge shall apply on the confirmed

total volume Transporter will utilize to meet increases (swing-up)

or decreases (swing-down) in actual flows at the Delivery Point

from confirmed nominated daily quantities under the linked

transportation agreement.

B. For a Shipper to request service hereunder, that Shipper must have

in effect a linked FTS or ITS Agreement consistent with Section

3.2A of this Rate Schedule IBS. The Access Request must reference

the linked transportation Agreement.

C. Intraday Access Requests may be submitted for new or increased

balancing services, consistent with the nomination deadlines

otherwise applicable under this Tariff. Intraday Access requests

may not be submitted which decrease the level of previously

confirmed Access Requests for the same gas day. The priority for

scheduling and confirming Intraday Access Request increases shall

be consistent with the priorities set forth in Section 6.2 of this

Rate Schedule IBS and Section 7.6 of the General Terms and

Conditions of this Tariff.

6.2 Transporter shall confirm Access Requests made each Gas Day under an

IBS Agreement which are consistent with this Rate Schedule IBS and,

in Transporter's reasonable judgment, Transporter has the line pack

capability to provide such service, Transporter determines that such

actions are not detrimental to its ability to satisfy any of its

existing obligations with higher priority service or to meet System

operational needs. It is understood that Transporter is not

providing a supply or storage service under this Rate Schedule IBS.
