ISS-M RATE SCHEDULE
INTERRUPTIBLE STORAGE SERVICE WITH MARKET-BASED RATES
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.
2. APPLICABILITY AND CHARACTER OF SERVICE
(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.
