Service under this Rate Schedule is available from Columbia Gas Transmission, LLC

(Transporter) to any Shipper, provided that: (i) Transporter has sufficient facilities and

storage capacity available to inject, store, and withdraw gas for Shipper; (ii) Transporter has

awarded capacity to Shipper under the provisions of Section 51 (Auctions of Storage Service with

Market-Based Rates) of the General Terms and Conditions (iii) Shipper has executed an ISS-M

Service Agreement with Transporter; and (iv) Shipper complies with all other applicable

provisions of this Tariff.




(a) Subject to the limitations set forth below, Transporter will inject and store

quantities and withdraw thermally equivalent quantities, less Storage Gas Loss, for Shipper.

This service will be provided on an interruptible basis and will apply to all gas designated for

storage under this Rate Schedule and delivered to Transporter to or for Shipper, up to the

Interruptible Storage Quantity (ISQ) set forth in Shipper's ISS-M Service Agreement.


(b) Service under this Rate Schedule, including all injections into and withdrawals

from storage will: (i) have the priority specified in Section 7 (Capacity Allocation) of the

General Terms and Conditions; (ii) be subject to interruption as provided in this Rate Schedule

or in Section 16 (Interruptions of Service) of the General Terms and Conditions; and (iii) be

subject to operational flow orders issued by Transporter to protect the integrity, including the

performance capability, of its storage facilities or as otherwise provided in this Rate Schedule

or in Section 17 (Operational Flow Orders) of the General Terms and Conditions.


(c) Subject to the limitations and requirements set forth in this Rate Schedule and in

Shipper's ISS-M Service Agreement, Shipper will be permitted to request that Transporter inject,

on an interruptible basis, quantities received by Transporter from or on behalf of Shipper and

designated for delivery to "ISS-M Storage". These nominations of injection quantities and all

resulting actual injections under this Rate Schedule must be completed within the first Month of

Shipper's ISS-M Service Agreement governing those quantities (the Injection Month).


(d) Shipper's aggregate injection quantities must not exceed Shipper's ISQ, and

Shipper's injection quantities on any Day in the Injection Month must not exceed Shipper's

Maximum Daily Injection Quantity (MDIQ). Shipper's MDIQ will be determined by: (i) multiplying

Shipper's ISQ and the applicable Storage Gas Loss by 110 percent and (ii) dividing the resulting

figure by the number of Days in the Injection Month.


(e) Transporter will make available to Shipper for withdrawal, on an interruptible

basis, quantities of gas thermally equivalent to the quantities actually injected for Shipper,

less Storage Gas Loss. Shipper may make withdrawals at any time during the term of Shipper's

ISS-M Service Agreement, unless otherwise extended pursuant to Section 5 of this Rate Schedule

(the Final Withdrawal Date).


(f) Shipper will not be permitted to increase its existing flowing quantities under

this Rate Schedule, regardless of the Interruptible Storage Quantity set forth in Shippers' ISS-M

Service Agreement, if the increase would cause a reduction of existing quantities flowing on

Transporter's system under a Service Agreement between Shipper and Transporter of equal or higher



(g) Shipper will remain responsible for all property or other taxes associated with the

quantities held for Shipper in storage under this Rate Schedule. Transporter will periodically

report to Shipper the quantities in storage, allocated by state, to enable Shipper to pay all

taxes associated with those storage quantities. All of Transporter's storage fields will be

treated conjunctively and each Shipper's storage gas will be deemed to be proportionally

allocated to all of Transporter's storage fields based on total working gas in storage.


(h) Transporter will assess Retainage on the transportation from ISS-M storage to the

delivery point for any quantities stored under this Rate Schedule.


(i) Service rights under an ISS-M Service Agreement may not be released and assigned.


(j) Awards of capacity under this rate schedule will be governed by Section 51 of the

General Terms and Conditions.
