GENERAL TERMS AND CONDITIONS
5. QUALITY OF GAS
The provisions set forth in this Section 5 shall apply to all gas received or delivered by
5.1 Natural or Artificial Gas
The gas received or delivered by Pipeline hereunder shall be a combustible gas
consisting wholly of, or a mixture of:
(A) Natural gas of the quality and composition produced in its natural state except
that the Pipeline may extract or permit the extraction of any of the
constituents thereof except methane.
(B) Gas generated by vaporization of Liquefied Natural Gas (LNG).
(C) Manufactured, reformed, or mixed gas consisting essentially of hydrocarbons of
the quality and character produced by nature in the petroleum, oil and gas
fields with physical properties such that when the artificial pipeline gas is
commingled with natural gas, the two become indistinguishable.
5.2 Total Heating Value and Wobbe Number
(A) The gas shall have a total heating value of not less than 967 nor greater than
1110 Btu per cubic foot of dry gas at a temperature of 60 degrees Fahrenheit and
under a pressure of 14.73 psia. The gas shall have a Wobbe Number of not less
than 1314 nor greater than 1400 (calculated using Total Heating Value (THV)),
dry, under standard conditions at 14.73 psia at 60 degrees Fahrenheit based on
the following mathematical definition and in accordance with Section 7 of these
THV / Sqrt SGas
THV = Total Heating Value (Btu/standard cubic feet)
SGas = Specific Gravity
Sqrt = Square Root of
(B) Both the total heating value at any time, for purposes of determining compliance
with GT&C Section 5.2(A), and the average total heating value for any billing
period shall be determined by gas chromatographic analysis using GPA 2172/API
MPMS 14.5 factors or any revision thereof, or by other methods mutually agreed
upon by Customer and Pipeline.
The gas shall be commercially free, under continuous gas flow conditions, from
objectionable odors, solid matter, dust, gums, and gum-forming constituents
which might interfere with its merchantability or cause injury to or
interference with proper operations of the pipelines, compressor stations,
meters, regulators or other appliances through which it flows.
