GENERAL TERMS AND CONDITIONS

(continued)

 

f. Specific Gravity. Specific gravity of the gas delivered shall be

determined with an Edwards or other standard type gravity balance

by test made as near the first of each month as practicable; or by

a recording gravitometer of standard manufacture installed at a

suitable location; or by use of on-line chromatography at a

suitable point on Transporter's line with the calculations based

on GPA Standard 2172; or by any other industry-approved method if

agreed to by Transporter and Shipper. When a recording

gravitometer is provided, the daily arithmetic average of the

gravity as recorded shall be used in computing gas volumes.

 

g. Total Heating Value. The total heating value of the gas

delivered/received shall be determined by Transporter by using a

gas chromatograph or other standard type of recording calorimeter,

which shall be so located, at a suitable point on Transporter's

line, in order that the Btu content of the gas delivered/received

may be properly obtained or by use of on-line chromatography at a

suitable point on Transporter's line with calculations based on

GPA Standard 2172; or by any other industry-approved method if

agreed to by Transporter and Shipper. When a recording

calorimeter or system chromatograph is used upstream of

Transporter's Compressor Station 16, the daily arithmetical

average of the readings from the record so obtained shall be

corrected to the basis of measurement provided, the result being

the heating value, to the nearest whole Btu of the gas delivered

during that period. When a system chromatograph is used

downstream of Transporter's Compressor Station 16, the daily

arithmetical average of readings from the record so obtained shall

be corrected to the basis of measurement provided, the result

being the heating value, to the nearest tenth Btu of the gas

delivered during that period. In the event that Transporter's

recording calorimeter or system chromatograph is not operating

properly, the total heating values shall be determined by

estimating an appropriate Btu for that location based upon the

best information available.

 

h. Moisture Content. For receipts and deliveries upstream of

Transporter's Compressor Station 16, the water vapor content of

the gas shall be determined at least once monthly, and shall be

properly taken into account in determining the total heating value

until the next following determination of water vapor content.

For receipts and deliveries downstream of Transporter's Compressor

Station 16 the water vapor content of the gas shall be determined

daily and shall be taken into account in determining the total

heating value. Gas with a water vapor content of seven (7) pounds

of water vapor per one thousand (1000) Mcf or less shall be

considered dry gas.
