3.QUALITY (Continued)


3.3 Determination of Gross Heating Value and Component Analysis



party questions such results within a period of sixty (60) days following

the determination thereof, then such results shall be deemed conclusive

and binding upon the parties hereto. Btu measuring equipment shall be

installed at a location or locations where the gross heating value of the

gas received or delivered hereunder may be reasonably determined.


3.4 Failure to Meet Specifications. Transporter or Shipper shall have

the right, exercisable by the giving of written or oral notice to the

other party, to require the remedy of any failure to deliver or redeliver

gas in accordance with the quality specifications set forth in Sections

3.1 and 3.2. In the event gas delivered by either party fails to conform

to such specifications, the receiving party may refuse to accept all or

any portion of such gas.




4.1 Unit of Volume. The unit of volume for the purpose of measurement

shall be one (1) cubic foot of gas at a base temperature of 60øF. and at

a base pressure of 14.73 p.s.i.a. Such measured volumes, converted to

Mcf, shall be multiplied by their gross heating value per cubic foot and

divided by 1,000 to determine MMBtu's received and delivered hereunder.

The unit of volume for the purpose of balancing total receipts and

deliveries of gas hereunder shall be one MMBtu.


4.2 Computation of Volume. The volumes of gas measured hereunder shall

be computed in accordance with specifications prescribed by the American

Gas Association, applied in a practical and appropriate manner. The

absolute atmospheric pressure used for volume calculations shall be the

average atmospheric pressure determined by calculations based on the

actual elevation above sea level of the meter at the place of measurement.
