GENERAL TERMS AND CONDITIONS
(c) by estimating the quantity of receipt or delivery based on receipts or deliveries
during preceding periods under similar conditions when the meter was registering
The correction period shall not exceed one (1) Year.
7.6 If at any time during the term of service a new method or technique is developed with respect
to gas measurement or the determination of the factors used in gas measurement, the new method
or technique may be substituted upon mutual agreement by both parties.
7.7 The parties agree to preserve for a period of at least three (3) Years or such longer period
as may be required by public authority, all test data, charts and other similar records.
8.1 Heat Content
Heat content shall mean the gross heating value per cubic foot of gas delivered at each point
of receipt and point of delivery. Gas delivered by Shipper to Transporter at each point of
receipt shall have a heat content not greater than 1069 Btu's per cubic foot nor less than 967
Btu's per cubic foot when determined on a pressure base of 14.73 psia and dry.
Transporter shall have the right to waive such Btu content limits if, in Transporter's sole
opinion, Transporter is able to accept gas with a Btu content outside such limits without
affecting Transporter's operations. The total heating value per cubic foot of gas shall be
determined at intervals of not more than thirty (30) Days by means of an instrument(s) of
standard manufacture accepted in the industry for this purpose or using a sample of gas
representative of the gas stream that is being delivered to Transporter or received from
Transporter at the point(s) of receipt or delivery.
In the event, however, that the heat content of Gas received by Transporter at any point
drops below the Btu level at which the MDQs of Transportation Service Agreements for
that receipt point are currently based and Transporter is unable to Transport Shipper's
Scheduled Daily Delivery from that receipt point due to the drop in the Btu level,
Transporter shall utilize the Curtailment provision of Section 11.4 of the General
Terms and Conditions.
For the purpose of calculating receipts and deliveries, the heat content of the gas so
determined at each such point shall be deemed to remain constant at such point until the next
determination. The unit of quantity for the purpose of determining total heating value shall
be one (1) cubic foot of gas on a dry basis at a temperature of sixty degrees (60ø) Fahrenheit
and an absolute pressure of 14.73 psia.
8.2 Freedom from Objectionable Odor and Matter
The gas received and delivered hereunder:
(a) shall be commercially free (at prevailing pressure and temperature) from objectionable
odors, dust, or other solid or liquid matter that might interfere with its
merchantability or cause injury to or interference with proper operation of the lines,
regulators, meters and other equipment of Transporter;
(b) shall not contain more than one quarter (1/4) grain of hydrogen sulfide per one
hundred (100) cubic feet of gas;
(c) shall not contain more than twenty (20) grains of total sulfur (including the sulfur
in any hydrogen sulfide and mercaptans) per one hundred (100) cubic feet of gas;
(d) shall not at any time have an oxygen content in excess of one percent (1%) by volume
and the parties shall make every reasonable effort to keep the gas free of oxygen;
