PART 1

GENERAL TERMS AND CONDITIONS

(Continued)

31.6 Release of Segmented Capacity. Shipper may release its segmented

capacity, as prescribed under § 6 of the General Terms and Conditions of this

Part, provided that the criteria under § 31.2 above are met for the duration

of the release or be subject to recall. Replacement shippers may re-release

segmented capacity.

31.7 System Integrity. Questar reserves the right at any time to use

discretion when providing segmentation in order to protect its system from

degradation of service. Questar may manage or limit segmentation when

necessary to maintain operational efficiency, flexibility and to maximize

capacity for the benefit of all shippers and reduce any risk of Questar being

prevented from fulfilling its contractual commitments. This may include the

use of OFOs or recall of capacity.

32. OFF-SYSTEM SERVICES

Questar may enter into transportation and/or storage agreements with

other interstate and intrastate pipeline and storage providers (off-system

capacity). In the event that Questar acquires off-system capacity, Questar

will use such capacity for operational reasons or to render service for its

shippers on the acquired capacity, pursuant to Questar's FERC Gas Tariff and

subject to Questar's currently approved rates. For purposes of transactions

entered into subject to this section, the "shipper must hold title"

requirement is waived on the acquired capacity.

33. APPLICABLE LAW

Any agreement executed pursuant to the terms and conditions of this

tariff shall be interpreted according to the laws of Utah without regard to

choice of law rule.
