(1) The Access Request, which shall constitute

Shipper's nomination under the IBS Agreement, shall specify the

volume and direction of the balancing service and must reference the

specific IBS Agreement, end-use facility or facilities and Delivery

Point(s) to which the service relates.


(2) For a Shipper to request service hereunder,

that Shipper must have in effect a linked FTS, FTS-G or ITS

Agreement consistent with Section 3.2(a) of this Rate Schedule IBS.

The Access Request must reference the linked transportation



(3) Intraday Access Requests may be submitted

hereunder which increase the level of service requested. Intraday

Access Requests may also be submitted which decrease the level of

service requested, but such a decrease shall not reduce the Access

Charges based on the original Access Request confirmed for the

decreasing Shipper that day unless Natural obtains additional

revenue from another Shipper under Rate Schedule IBS as the result

of an intraday nomination for an increase Natural can only confirm

because of the decrease. The reduction in Access Charges for the

decreasing Shipper shall be limited to the additional revenue which

Natural obtains from the intraday nomination for an increase in

possible by the decrease, but in no event shall the reduction result

in negative Access Charges for the decreasing Shipper. Such

intraday Access Requests may be submitted on the same schedule as

other intraday nominations.

will post on each day, at least two (2) hours before nominations are

due for that day, whether service under Rate Schedule IBS is likely

to be available on that pipeline segment.

satisfaction of Natural's firm obligations or any interruptible

obligations which may be of higher priority or to Natural's system

operational needs, it being understood that Natural is not

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

Natural will not confirm any Access Request if granting such a

request would be detrimental to Natural's ability to provide any

firm service or any priority interruptible rights associated with a
