GENERAL TERMS AND CONDITIONS (Continued)

21. RECEIPT AND DELIVERY FACILITIES

21.1 General. This section applies only to those receipt or delivery

facilities contemplated by Section 1(b) of Rate Schedules TF-1, TF-2,

TFL-1 and TIL-1 and Section 1(a) of Rate Schedule TI-1 needed to

accommodate customer requests. This section does not apply to receipt

or delivery facilities constructed by Transporter to accommodate new

transportation commitments solicited by Transporter through an open

season. This section is not intended to limit who may own, operate,

install or pay for facilities upstream of a receipt point or downstream

of a delivery point. It is the Shipper's responsibility to assure that

all facilities installed and owned by Shipper or any other third party

upstream of a receipt point or downstream of a delivery point comply

with all applicable governmental regulations and design requirements for

their intended use (i.e., pressure, control, etc.).

21.2 Construction, Operation, and Ownership.

(a) Transporter will construct, own, operate and maintain all

receipt and delivery facilities unless otherwise agreed to in

writing by Transporter and Shipper. Regardless, Transporter will

install, own and operate all taps and related valves or check

valves on its transmission lines. Facilities to be constructed or

modified may not compromise the operational integrity of

Transporter's transmission system, and construction is subject to

acquiring necessary regulatory approvals.

(b) If in its sole discretion Transporter determines that joint

ownership of the facilities will not be detrimental to

Transporter's system, Transporter will offer Shipper the option to

acquire an ownership interest in the facilities in proportion to

the amount of construction costs for which Shipper is responsible.

Transporter will not transfer any ownership interest to Shipper

prior to payment in full of the applicable cost of service

described in Section 21.3(b).

Shipper, Shipper will coordinate construction of such facilities

with Transporter so that Transporter may reasonably have

inspectors at the site during construction. All such facilities

must include any rights-of-way necessary to access facilities for

inspection and maintenance. Any such facilities constructed by

Shipper must be in accordance with Transporter's specifications.

Transporter must approve related design drawings and bills of
