GENERAL TERMS AND CONDITIONS

 

 

3. MEASUREMENT (Cont'd.)

 

Transmission Measurement Committee Report No. 8 "Compressibility

and Supercompressibility for Natural Gas and Other Hydrocarbon

Gases." If the composition of the gas is such as to render the

above procedure inapplicable, other methods for determination of

the deviation factors, mutually agreed upon by Shipper and

Transporter, shall be used.

 

3.7 Total Heating Value. The total heating value of the gas per cubic

foot shall be determined for any month by taking the average of the

heating values as recorded each day by a calorimeter or chromato-

graph or as determined by chromatographic analysis of a sample of

gas, or methods outlined in AGA Gas Measurement Report No. 5, or

any other method mutually agreed upon by Transporter and Operator.

 

4. MEASURING EQUIPMENT

 

Unless otherwise agreed upon, Transporter or Transporter's designee will

install, as necessary, maintain and operate measuring stations at or

near the receipt and delivery point(s) properly equipped with displace-

ment, turbine or orifice meters, gas samplers, chromatographs and other

necessary measuring equipment by which the quantity of gas delivered

hereunder shall be measured. The cost of Transporter's or Transporter's

designee's installing any incremental measuring facilities necessary

with respect to the receipt and delivery of gas shall be borne by the

Shipper(s) of such gas, unless otherwise expressly agreed. Transporter

may require Shipper or Operator to provide records and/or charts from

orifice meters measuring deliveries of gas by Shipper to Transporter

within the period of time prescribed by Transporter.

 

Orifice meters shall be installed and operated in accordance with speci-

fications recommended in Gas Measurement Committee Report No. 3 of the

American Gas Association, as the same may be amended from time to time,

applied in a practical manner. Displacement or turbine meters, if used,

shall be installed and gas volumes computed, in accordance with

generally accepted industry practices.
