4.5 Pooling. If requested by a Shipper or supplier on

Transporter's system, Transporter will offer at least one pool.

Deliveries from Receipt Points should be able to be delivered

directly into at least one pool, and Delivery Points should be

able to receive quantities from at least one pool, excluding

non-contiguous facilities.

4.6 Intra-day Nominations. An Intra-day nomination is

a nomination submitted after the nomination deadline whose

effective time is no earlier than the beginning of the gas day

and runs through the end of that gas day. Intra-day nominations

may be used to nominate new supply or market. Intra-day

nominations can be used to request increases or decreases in

total flow, changes to receipt points, or changes to delivery

points of scheduled gas. All nominations, including Intra-day

nominations, should be based on a daily quantity; thus, an

intra-day nominator need not submit an hourly nomination.

Intra-day nominations should include an effective date and time.

The interconnected parties should agree on the hourly flows of

the Intra-day nomination, if not otherwise addressed in

Transporter's contract or tariff. Intra-day nominations do not

rollover (i.e. Intra-day nominations span one day only). Intra-

day nominations do not replace the remainder of a standing

nomination. There is no need to re-nominate if Intra-day

nomination modifies existing nomination.
