GENERAL TERMS AND CONDITIONS
19. LIMITATIONS OF NORTHERN'S OBLIGATION TO
PROVIDE FIRM SERVICES
1. In the event a curtailment must be effected, the smallest affected
area will be localized beginning with individual points, followed
by an operational zone, Market/Field Area, and up to the entire
system, in that order. Curtailment will proceed in the following
(i) TI will be curtailed on the basis of lowest price first.
(ii) Firm service at primary or alternate points will then be
curtailed on a pro rata basis.
2. If Shipper takes gas in excess of the volume of gas authorized for
delivery on any day Northern has ordered reduced deliveries, Shipper
shall be subject to a penalty for takes of gas in excess of the
authorized volume, without any tolerance. The penalty shall be equal to
the Punitive DDVC rate set forth on Sheet No. 53. Penalty revenues
shall be credited to Shippers in accordance with Section 57 of the
GENERAL TERMS AND CONDITIONS of this Tariff.
3. If TI receipt point volumes continue to flow during a curtailment at
Northern's request, such volumes during such curtailment will not be
subject to receipt point scheduling penalties.
4. Northern shall also have the right to reasonably limit supply
service and/or reduce receipts or deliveries of natural gas in
conjunction with the throughput capacity under Throughput Service
Agreements on part or all of Northern's system according to the above
1) to permit maintenance, repair, overhaul, replacement or construction
of pipelines, compressors, metering, regulating and other production,
and transmission facilities and equipment; 2) to assure the
availability of capacity for receipts or deliveries equitably under
Northern's firm Rate Schedules included in this Tariff in cases where
natural gas does not conform to the quality specifications contained in
the Tariff. Northern shall provide Shipper reasonable advance notice of
routine maintenance, repair, overhaul or replacement.
5. Northern shall have the right on a nondiscriminatory basis to restrict
the hourly takes of gas by the Shipper in the Market Area to 6.3% of the
entitlement plus any excess volumes authorized under the Firm Service
Agreement. Such restrictions may be ordered by Northern, when necessary
in Northern's judgment to maintain operational integrity, and shall be
complied with by the Shipper.
6. Upon reasonable request of Shipper, Northern shall furnish
information and copies of affidavits with respect to curtailments of
Firm Service ordered under the provisions of this Section.
