OPT RATE SCHEDULE
OFF-PEAK FIRM TRANSPORTATION SERVICE (Cont'd)
(e) Transporter shall not be obligated on any Day to accept gas in excess of the lesser of (i)
Shipper's Transportation Demand plus Retainage, or (ii) Shipper's Scheduled Daily Receipt Quantity.
Transporter also shall not be obligated on any Day to deliver more gas to Shipper than the lesser of
(i) Shipper's Transportation Demand, (ii) Shipper's Scheduled Daily Delivery Quantity or (iii) the quantity of
gas Transporter receives for Shipper less Retainage. For the purpose of balancing any imbalances in Shipper's
account, Shipper may deliver or take quantities in excess of the above limitations in accordance with the
provisions of Section 6 (Nominating, Scheduling, and Monitoring) and Section 7 (Capacity Allocation) of the
General Terms and Conditions.
(f) Service rights under an OPT Service Agreement may be released and assigned in accordance with
Section 14 (Release and Assignment of Service Rights) of the General Terms and Conditions. Service to a
replacement shipper under any such release and assignment shall be subject to the provisions set forth in this
Rate Schedule and in the applicable General Terms and Conditions.
3. OPERATING CONDITIONS
(a) Service under this Rate Schedule is subject to the operating conditions set forth in this
Section and in applicable provisions of the General Terms and Conditions.
(b) Transporter in its reasonable discretion may interrupt service to Shippers under this Rate
Schedule, consecutively or nonconsecutively, up to the number of days (30 or 60) provided in Shipper's OPT
Service Agreement with Transporter. Based on forecasted system conditions, Transporter will post a notice at
least 24 hours prior to the start of the Gas Day informing shippers of the anticipated availability of service
under this Rate Schedule. If, based on forecasted system conditions, OPT is listed as "unavailable" in the
advance notice, Shippers will still be permitted, but will not be required, to submit nominations for service
and days of allowable interruption will be calculated as set forth in Section 3(d), below. If shippers elect
not to submit a nomination for service under Rate Schedule OPT, services with a lower scheduling priority may
be scheduled to the extent capacity is available.
(c) In allocating such interruptions among those Shippers receiving service on the portion of
Transporter's system in which interruptions are to be made, Transporter shall (i) interrupt service to those
Shippers having the greatest number of days of allowable interruption remaining during that November 1 - March
31 period, and (ii) among those Shippers with an equal number of remaining days of allowable interruption, on
a pro rata basis. Alternatively, Transporter shall interrupt service in accordance with an alternate
allocation methodology if, before issuance of any notices of interruptions, such methodology has been agreed
to in writing by Transporter and all Shippers whose service would be affected. If weather or other
circumstances beyond Transporter's control mandate interruptions at delivery points for more than the number
of days specified in Shipper's Service Agreement, service under this Rate Schedule shall be interrupted before
service under other firm Rate Schedules and the provisions of paragraph (f) below shall apply.
(d) For purposes of calculating periods of allowable interruption under this Rate Schedule an
interruption at a secondary delivery point shall not reduce Shipper's number of remaining days available for
interruption. An interruption at a primary delivery point shall constitute an interruption for purposes of
this Rate Schedule whenever Transporter notifies Shipper twenty-four (24) hours in advance of the Gas Day that
Transporter will be unable to render service up to the level of Transportation Demand specified in the OPT
Service Agreement. Days of interruption at primary delivery points shall be calculated as follows:
