GENERAL TERMS AND CONDITIONS (Continued)

2. QUALITY

2.1 The provisions set forth in this Section 2 shall apply to all gas

received by Transporter under this Tariff.

(a) The natural gas shall have a Total Heating Value of not less than

967 British thermal units per Cubic Foot (Btu/cf) and not greater

than 1110 Btu/cf of gas volume (measured on a dry basis). The gas

shall have a Wobbe Number of not less than 1298 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 3 of these GT&C:

THV / Sqrt SGgas

Where: THV = Total Heating Value (Btu/scf),

SGgas = Specific Gravity, and

Sqrt = Square root of.

Shipper may subject, or permit the subjection of, the natural gas

to compression, cooling, cleaning and other processes and helium,

natural gasoline, butane, propane, and any other hydrocarbons

except methane may be removed prior to delivery to Transporter.

In the event that the Total Heating Value of gas, per Cubic Foot,

when determined as provided in Section 3.2 hereof, and subject to

Section 2.4, falls below 967 Btu/cf, or is above 1110 Btu/cf,

Transporter shall have the option to refuse to accept said gas so

long as said Total Heating Value remains below 967 Btu/cf or above

1110 Btu/cf, respectively.

(b) All gas shall be commercially free (at prevailing pressure and

temperature in Transporter's pipeline) from objectionable odors,

dust, hydrocarbon liquids, water or other solid or liquid matters

that might interfere with its merchantability or cause injury to

persons or properties or interference with proper operation of the

lines, regulators, meters or other appliances through which it

flows and which might become separated from the gas in

Transporter's facilities, and Transporter may require furnishing,

installation, maintenance and operation of such drips, separators,

heaters and other mechanical devices as may be necessary to effect

compliance with such requirements (the installation of such

equipment shall be subject to prior approval of Transporter as to

the design and construction of such facilities, which approval

shall not be unreasonably withheld).

(c) All gas shall contain no more than twenty (20) grains of total

sulphur, nor more than one fourth (1/4) of one grain of hydrogen

sulphide per one hundred (100) Cubic Feet as determined by methods

to be mutually agreed upon.

(d) All gas shall not exceed one-tenth of one percent (0.1%) by volume

of oxygen.

(e) All gas shall not contain more than four percent (4%) by volume of

a combined total of carbon dioxide and nitrogen components;

provided, however, that the total carbon dioxide content shall not

exceed three percent (3%) by volume nor shall the total nitrogen

content exceed three percent (3%) by volume.
