-----------------

(4) Rules regarding the allocation of injections

by leg to determine such sourcing are set out in Section 5.6(c) of

the General Terms and Conditions of this Tariff. In applying this

subsection (c), all receipts on Natural's system on the Amarillo

Line and north of Station 311 on the Gulf Coast Line shall be

deemed to be sourced on the Amarillo Line and injected into the

Amarillo Storage Point in the Iowa-Illinois Receipt Zone and all

other receipts shall be deemed to be sourced on the Gulf Coast Line

and injected into the Gulf Coast Storage Point in the Iowa-Illinois

Receipt Zone, except as set out in subsection (5) below.

(5) Notwithstanding the foregoing, Natural shall

post prior to the beginning of each month, at least twenty-four

(24) hours before first-of-the-month nominations are due, the

extent (if any) to which receipts between Station 110 and Station

311 will be treated as Gulf Coast receipts. Natural will designate

such receipts as Gulf Coast receipts for that month to the extent

reasonably feasible operationally. Such designation may be reduced

only prospectively through issuance of an Operational Flow Order or

in the subsequent month's posting. Natural shall also review such

designations daily and may change the designation by a posting

prior to the time nominations are due for that day; provided,

however, that the volume designated as Gulf Coast receipts in a

monthly posting may not be reduced during a month by such daily

postings. Natural shall also post prior to each month, at least

twenty-four (24) hours before first-of-the-month nominations are

due for that month, whether the restrictions on Shipper's

cumulative storage balance on each leg (as a percentage of MSV) can

be relaxed for a specified time period. Any posting hereunder

shall specify clearly which restrictions are being modified and the

magnitude and duration of the modification.

5.4 (a) A Shipper must have in storage under this Rate

Schedule DSS at least ninety-five percent (95%) of its MSV at some

time during the period from October 15 through November 15. If

Shipper fails to meet this requirement, its MSV for that year shall

be deemed to be equal to the greatest volume in storage during that

period. If the maximum volume in storage during that period is

less than ninety-five percent (95%) of Shipper's MSV, but is equal

to or greater than ninety percent (90%) of Shipper's MSV, its MDQ

(in the aggregate and at each Delivery Point) shall be reduced to

seventy-five percent (75%) of the MDQ in the DSS Agreement, solely

for the purposes of determining its WQ during the ensuing

withdrawal cycle. If the
