GENERAL TERMS AND CONDITIONS

(Continued)

3.4 Temperature. The temperature of the Gas shall be

determined at each point of measurement by means of a

properly installed recording thermometer or temperature

transmitter of standard manufacture acceptable to both

parties.

3.5 Specific Gravity. The specific gravity of the Gas shall

be determined at each point of measurement by continuous

sampler or other methods mutually agreeable to both

parties.

3.6 Supercompressibility. The supercompressibility of the

Gas (deviation from the laws for ideal gases) shall be

determined by one of the following methods:

(a) By use of Burnett type apparatus. Such

determination to be made within 30 Days of

commencement of service under Rate Schedules FT and

IT and annually thereafter.

(b) Or, if agreeable to Shipper, by use of the tables

or, formulae published by the American Gas

Association in conjunction with the Gas Measurement

Committee Report referred to in Section 3.6.

Determinations of the molecular percentage of

nitrogen and carbon dioxide in the Gas will be made

within 30 Days of commencement of deliveries under

Rate Schedules FT and IT and at least quarterly

thereafter. The molecular percentage of nitrogen

and carbon dioxide thus determined will be used to

determine the supercompressibility factors during

the ensuing period, with corrections for specific

gravity, temperature and pressure.
