GENERAL TERMS AND CONDITIONS (Continued)

50. SEGMENTATION OF CAPACITY (Continued)

50.3.4 A new request(s) for segmentation that would utilize

that portion(s) of the system utilized in the segmented

transaction. In the event of a new request(s) for segmentation,

Transporter shall review the existing Shipper's use of the

segmented capacity. If during the previous thirty (30) days, the

Shipper has not fully utilized its segmented capacity, such

segmented capacity shall be reduced to the highest daily usage

during that period and the remaining capacity shall be assigned

to the new segmentation request(s) in the order such request(s)

are received. Transporter shall provide the Shipper no less than

one (1) business day notice that the segmented capacity shall be

reduced.

following prerequisites for segmentation to ensure Transporter can

provide segmentation without detriment to any Shipper's firm

transportation service.

between Shipper's currently effective primary points of receipt

and delivery as designated on Shipper's Firm Transportation

Service Agreement.

50.4.2 Segmentation capacity may not exceed Shipper's primary

capacity on any individual segment.

50.4.3 Segmentation shall be permitted only in the currently

effective single-direction of flow, from the primary point of

receipt to the primary point of delivery as provided in the

Shipper's Firm Transportation Service Agreement.

firm capacity at the requested point(s) of receipt and delivery.
