GENERAL TERMS AND CONDITIONS

(Continued)

 

5. QUALITY OF GAS

 

The provisions set forth in this Section 5 shall apply to all gas received or delivered by

Pipeline.

 

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

GT&C:

 

THV / Sqrt SGas

 

Where:

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.

 

 

5.3 Composition

 

(A) Solids:

 

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.
