GENERAL TERMS AND CONDITIONS

----------------------------

(continued)

 

d. Vitco shall be responsible for the taking of samples at the

Delivery Point for the determination of the heating value of the

gas delivered. The results shall be applied to gas deliveries for

the day on which the sample is taken and for following days until

a new sample is taken. Shipper shall have the right to witness

the sampling and/or the Btu determination performed by Vitco.

 

e. The flowing temperature of the gas shall be determined by the

means of a recording thermometer of standard make acceptable to

both Vitco and Shipper, and the average reading each day during

which gas was flowing shall be deemed the gas temperature and

used in computing the volumes of gas delivered and redelivered

during such day.

 

f. The specific gravity of the gas shall be determined upon initial

receipt and redelivery and thereafter once each month at the

point where gas is metered hereunder, and the results of such

determination shall be used in computing the volumes of gas

metered at such point during the following calendar month. A

gravitometer of standard make and checked by the method pre-

scribed in American Petroleum Institute code No. 5O-A and

amendments thereto shall be used to determine the gravity, or at

Vitco's option, the gravity shall be determined by means of a

recording gravitometer of standard make and the average reading

each day during which gas was flowing shall be used in computing

the volumes of gas metered at such point during such day.

 

g. The measurement shall be corrected for the deviation of gas from

Boyle's law at the pressures and temperatures under which gas is

delivered and redelivered hereunder.

 

h. For the purposes of measurement and meter calibration, the atmos-

pheric pressure shall be assumed to be constant at fourteen and

seven-tenths (14.7) pounds per square inch, irrespective of

variations in natural atmospheric pressure from time to time.

 

i. The water content shall be determined by such intervals as shall

be found necessary in practice by use of a Bureau of Mines dew

point tester and utilizing tables derived from Illinois Gas

Institute Research Bulletin No. 8 or by such other table or

method as shall be mutually agreed upon.
