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:
