RATE SCHEDULE IBS (continued)

7.3 Any Unauthorized Overrun Service Charge billed and collected by

Transporter shall be refunded, net of cost, pursuant to Section 37

of the General Terms and Conditions of this Tariff. Unauthorized

Overrun Service Charges stated above may apply to overrun quantities

parked or loaned in violation of the Directional Notice or Critical

Time orders.

7.4 In each instance when a Unauthorized Overrun Service Charge is

incurred, Transporter shall have the right to review the

circumstances surrounding the Unauthorized Overrun Service Charge

incurrence and, in its judgment, may waive all or a portion of the

Unauthorized Overrun Service Charges. Any such waiver shall be

granted on a non-discriminatory basis to all Shippers that incurred

an Unauthorized Overrun Service Charge in that instance. Such

waiver, if granted, shall be posted on Transporter's Interactive

Website, as required by applicable FERC rules and regulations.

7.5 Further, any Unauthorized Overrun Service Charge shall be waived by

Transporter if there were no operational problems caused as a result

of the unauthorized overrun which led to the application of such

charge to a Shipper; however, in the event of such waiver the

Authorized Overrun Service Charge shall be payable by Shipper. If

Transporter does not waive an Unauthorized Overrun Charge in the

circumstances described in this section, Transporter shall, upon

request from a Shipper assessed an Unauthorized Overrun Service

Charge, provide a written explanation of the reason the Unauthorized

Overrun Service Charge was not waived.

8. MANDATORY BALANCING PROVISIONS

8.1 Mandatory Balancing shall apply where an IBS balance remains and is

not rectified: (a) at the end of the term specified in any

applicable IBS Agreement; or (b) where Shipper fails to comply with

the Payback provisions of Section 6 hereof to eliminate the IBS

balance; and (c) the Shipper fails to eliminate the IBS balance

after Transporter's notice is given pursuant to Sections 8.2 or 8.3

hereof.

8.2 Transporter may require Mandatory Balancing effective the next Day

prior to issuing Critical Time Operational Flow Orders pursuant to

the notice provisions of Section 36.6 of the General Terms and

Conditions of this Tariff, if Transporter reasonably determines that

doing so would facilitate System operations and minimize the

frequency and severity of Operational Flow Orders in the affected

region(s).
