GENERAL TERMS AND CONDITIONS (Cont'd)

25.9 Waiver.

(a) Transporter, in its reasonable discretion and judgment, exercised on a not unduly discriminatory

basis, may accept gas that does not conform to the quality specifications in Section 25, provided that

Transporter determines that such acceptance will not interfere with its ability to: (1) maintain an acceptable

gas quality in its pipeline through prudent and safe operation of Transporter's pipeline system and any related

storage facility; (2) ensure that such gas does not affect Transporter's ability to provide service to its

customers consistent with the applicable Rate Schedule and these General Terms and Conditions; and (3) ensure

that such gas does not adversely affect Transporter's ability to deliver gas at its delivery points. All

requests for waiver subsequent to the effective date of this Section 25.9 shall be submitted to Transporter in

writing. Transporter will post any waivers granted pursuant to this section on its EBB.

(b) All waivers granted pursuant to this Section shall be subject to suspension, to the extent

necessary to (i) ensure the operational integrity of Transporter's system, (ii) enable Transporter to meet its

firm service obligations, (iii) facilitate the flow of natural gas during times of emergency and/or periods of

force majeure, or (iv) for failure to comply with specifications for which the waiver was granted, such as a

deviation from the historical composition or volume. The duration of suspension shall vary depending on the

specific circumstances and conditions presented. Notice of suspension shall be posted on Transporter's EBB and

shall be immediately effective. The notice shall provide the ground(s) for such suspension.

to reflect significant changes in historic operating conditions on Transporter's system. To the extent

possible, Transporter will provide Shipper with thirty (30) days prior written notice of revocation, and will

post the notice of such revocation on Transporter's EBB. The notice shall provide the ground(s) for such

revocation.

(d) All disputes concerning the grant, denial, suspension or revocation of waivers pursuant to this

Section shall initially be presented to Transporter in accordance with the Complaint Resolution Procedure set

forth in Section 30 of the General Terms and Conditions of this Tariff.
