6. QUALITY OF GAS

 

6.1 Natural or Artificial Gas. The gas received or delivered by

Pipeline under this Tariff 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 Pipeline may extract or permit

the extraction of any of the constituents thereof, except

methane, that are objectionable as detailed in Section 6.3;

 

(b) Gas generated by vaporization of liquefied natural gas; or

 

(c) Manufactured, reformed, or mixed gas consisting essentially

of hydrocarbons of the quality and character produced by

natural causes in petroleum, oil, and gas fields with

physical properties such that when artificial pipeline gas

is commingled with natural gas, the resulting mixture is

indistinguishable from natural gas complying with this

Tariff’s specifications.

 

6.2 Total Heating Value.

 

(a) No gas tendered to Pipeline shall have a Total Heating

Value at the Receipt Point below 950 Btu per CF or above

1075 Btu per CF, provided that no gas received from Transco

shall have a Total Heating Value above 1100 Btu per CF.

 

(b) The Total Heating Value shall be determined by gas

chromatographic analysis, or by other method mutually

agreed on by Shipper and Pipeline.

 

6.3 Merchantability. All gas shall be commercially free, under

continuous gas flow conditions, from objectionable odors (except

those required by applicable regulations), liquid or solid

matter, dust, gums, gum forming constituents, liquefiable

hydrocarbons, or any other objectionable matter that might

interfere, in Pipeline’s reasonable judgment, with the

merchantability of the gas or cause injury to or interference

with proper operations of the pipelines, compressor stations,

meters, regulators, or other facilities or appliances through

which it flows.

 

6.4 Composition.

 

(a) Non-Hydrocarbon Gases. The gas shall not contain more than

four percent (4%) by volume of a combined total of non-

hydrocarbon gases.
