25. PENALTY REVENUE CREDITING MECHANISM

Transporter shall establish an account to which it will credit all penalties imposed and

collected and debit all costs incurred and paid out as a result of any activities or

circumstances for which a penalty may be imposed under this FERC Gas Tariff, Second Revised

Volume No. 1. Such activities or circumstances shall include but not be limited to: Shipper

imbalances as described in Section 3.3 of the General Terms and Conditions; scheduling

deviations as described in Section 3.5 of the General Terms and Conditions; daily imbalances as

described in Section 2 (j) of Rate Schedule EFT, Enhanced Firm Transportation Service; and

each year or the end of any month during which such balance exceeds $1,000,000.00 by crediting

the applicable Shipper's invoice for the following month's service, or by issuing a check or

wire transfer. Transporter may also distribute the account balance at any other time Transporter

deems necessary for administrative purposes. The balance shall be allocated to all shippers

based upon the ratio of each Shipper's total transportation charges for each of the preceding

months since the last distribution date (whether or not a distribution was made) during months

for which that Shipper did not incur any penalties, to the total of all such transportation

charges for all Shippers for such period. Transporter shall post calculations supporting any

such distribution on its Web site for at least sixty (60) days following such distribution.
