3. QUALITY (Continued)


The gas shall be free of water and hydrocarbons in liquid form at

the temperature and pressure at which the gas is delivered and in no

event shall have a water content in excess of seven pounds in vapor phase

per million cubic feet.


3.3 Determination of Gross Heating Value and Component Analysis. The

party operating the measurement equipment shall determine the gross

heating value of the gas delivered and its component analysis at

reasonable intervals. Such determination shall be made using either an

on-line chromatograph or by chromatographic analysis of a representative

sample of gas taken with a continuous sampler. Transporter may at its

option allow the use of spot samples. If at any time and for any reason

Shipper or Transporter should question the results of any spot sampling,

a redetermination shall be made and the redetermination mutually

acceptable to the parties shall be used; provided, however, if neither

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. 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, as evidenced by the latest chromatograph analysis

derived from an on-line chromatograph or from a sample taken manually and

analyzed by a chromatograph, or from any other verifiable evidence, the

receiving party may refuse to accept all or any portion of such gas.
