To the extent operationally feasible, any shipper receiving firm

transportation service under Rate Schedule FT-1 may segment its capacity

at telemetered points of receipt and delivery pursuant to the provisions

of this section.

50.1 Segmentation shall be accomplished on Transporter's system by

submitting a Segmentation Request Form, as provided in Subsection 50.8

of these General Terms and Conditions, specifying the desired

segmentation point(s) of receipt and delivery. Segmentation requests

shall be submitted to Transporter by Shipper via facsimile or other

acceptable electronic communication mechanism, as described in Section 8

of these General Terms and Conditions, no less than five (5) business

days prior to the day on which Shipper desires such segmentation to be

effective.

50.2 Transporter shall grant a segmentation request if the

prerequisites for segmentation listed in Subsection 50.4 are met. If

the segmentation request involves the release of capacity, the

requirements in Section 17 of these General Terms and Conditions shall

also apply.

50.3 After approval, the ability to segment on Transporter's system

shall be suspended, reduced or terminated only under the following

circumstances:

50.3.1 Existence of a critical situation requiring an

Operational Flow Order (OFO), as more fully described in Section

16 of these General Terms and Conditions, affecting the segmented

transaction. The suspension period shall be for the term of the

OFO.

50.3.2 An operational or contractual change on the system that

would impair the ability of Transporter to continue the segmented

transaction.

50.3.3 A request for uncommitted capacity that would utilize

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

Transporter shall provide the Shipper using the segmented

capacity no less than a one (1) business day notice in advance of

suspension, reduction or termination of segmentation.
