GENERAL TERMS AND CONDITIONS
All gas to be received from Shipper into the Northern pipeline system
shall conform to the following specifications:
a) The gas shall be commercially free from objectionable odors,
solid matter, dust, gums and gum-forming constituents, or any
other substance which might interfere with the merchantability
of the gas, or cause injury to or interference with proper
operation of the lines, meters, regulators, or other appliances
through which it flows.
b) Oxygen - less than or equal to 0.02% by volume.
c) Hydrogen sulfide - less than or equal to 1/4 grain/Ccf.
d) Total Sulphur - less than or equal to 20 grains/Ccf.
e) Carbon Dioxide - less than or equal to 1.0% by volume.
f) Water - less than or equal to 6 pounds/MMcf.
g) Heating Value - greater than or equal to 950 Btu/Cubic Foot.
h) The temperature shall be less than or equal to 120 degrees
If any gas received by Northern shall fail at any time to conform to the specifications
set forth above, Northern may refuse to accept delivery pending correction by the other
party. Northern may, on a basis that is not unduly discriminatory, elect to accept gas
which fails to meet specifications.
A Shipper on Northern's system shall have the option to: 1) receive a credit from Northern for
liquid revenues, or 2) enter into a separate processing arrangement with a plant operator,
pursuant to the provisions set forth in this Tariff.
Northern shall have the unconditional right to commingle gas received from any Shipper or
source for transportation under this Tariff with gas received from other Shippers or sources.
Northern's obligation under this Tariff shall be to deliver thermally equivalent volumes, less
fuel, from the points of receipt to the points of delivery under the terms and conditions of
the applicable Rate Schedules of this Tariff, and each party tendering gas to Northern shall
recognize that gas delivered by Northern has been commingled from various sources and will not
be the same molecules, or contain the identical constituents, as the gas received by Northern.
No party tendering gas to Northern shall have the right to any particular constituent in the
gas tendered, including but not limited to, liquids and liquefiable hydrocarbons while such
constituents are entrained in the gas stream. However, in the event a Shipper or its designee
elects to retain the right to process gas tendered to Northern, a Shipper or its designee
which has contracted with any processing plant will be entitled to an agreed-upon share of
plant products, revenue or other consideration, as the case may be, attributable to gas
processed at a processing plant in accordance with the allocation methodology agreed to under
subparagraph (a) or a Shipper or another party which has not contracted with any processing
plant will be entitled to a share of the liquids revenues in accordance with the allocation
methodology under subparagraph (b). Any Shipper may elect to retain the right or elect to
appoint to its designee as the party with the right to process gas tendered to Northern for
the removal of liquids and liquefiable hydrocarbons under the options set forth below. For
the purposes of this Section, Shipper's designee may be any party designated by Shipper to
Northern by written notice, (including but not limited to a working interest owner in a well
from which Shipper purchases gas, a marketer, broker, or the operator of a gas processing
plant) and such designee need not be a designee under Shipper's Service Agreement for any
purpose such as nomination, scheduling, billing or payment.
