GENERAL TERMS AND CONDITIONS

(continued)

30. SEGMENTATION OF CAPACITY (continued)

releasing or replacement Shipper, unless Transporter agrees

otherwise. If a Shipper, in accordance with the provisions of

this Tariff, changes a primary point, Transporter shall not be

obligated to reserve firm capacity to reinstate the former primary

point upon expiration of the segmentation or the capacity release.

30.4 In addition to Transporter's right to determine operational

feasibility on a case-by-case basis, as set out in Section 30.7

below, a purported segmentation of firm capacity (whether for a

Shipper's own use or on release) shall not be operationally

feasible if: (a) Pools are nominated as Segment Receipt Point(s),

absent a determination by Transporter that the proposed

segmentation would not result in an impermissible overlap of

capacity or otherwise result in a greater level of entitlement

than the entitlement under the original Service Agreement prior to

segmentation; (b) the segmentation would purport to result in

primary capacity rights with respect to a Primary Path Segment in

a direction opposite to the direction of the Primary Path under

the Service Agreement being segmented; or (c) a proposed

segmentation would purport to identify a Primary Path or Primary

Path Segment within Transporter's Reticulated System.

30.5 Subject to the provisions of this Tariff, including but not

limited to, the provisions of this Section 30, a Shipper may

segment its Primary Path in a manner such that capacity in the

direction of the Primary Path and capacity in the opposite

direction of the Primary Path, each within applicable Contract

Limitations, is used to make deliveries to the same Delivery Point

at the same time. Transporter shall not be obligated to accept

nominations or releases of capacity for any purported Primary Path

Segment or combination of Primary Path Segments that would result

in an impermissible overlap of capacity or otherwise result in a

greater level of entitlement than the entitlement under the

original Service Agreement prior to segmentation. A releasing

Shipper may not re-release a released Primary Path Segment until

such time as the releasing Shipper either recalls the released

Primary Path Segment or the released Primary Path Segment reverts

to the releasing Shipper at the end of the release term.

Replacement Shippers that desire to re-release a released Primary

Path Segment may only release transportation capacity within their

acquired Primary Path Segment. The sum of capacity released in

any Primary Path Segment cannot exceed the level of entitlement

under the original Service Agreement prior to segmentation.
