GENERAL TERMS AND CONDITIONS

 

 

3. MEASUREMENT REPORTING AND SCHEDULING OF RECEIPTS AND DELIVERIES

 

3.1 Reporting Unit of Measurement

 

The reporting unit for energy quantities transported and used by Company will

be Dekatherms at the standardized reporting basis as defined by NAESB WGQ.

 

3.2 Measurement Reporting

 

The volume and the Total Heating Value of gas received and delivered by Company

shall be determined for all purposes, including invoicing by Company and

payment by Shippers and LMS-MA and LMS-PA parties, on the basis of the

electronic measurement equipment installed by Company at receipt and delivery

points.

 

3.2.1 Unit of Volume

 

The unit of volume, for the purpose of measurement, shall be defined as

one cubic foot (1cf) of gas at a temperature of sixty degrees (60)

Fahrenheit, and at a pressure of thirty-three hundredths (.33) pounds

per square inch above an assumed atmospheric pressure of fourteen and

four tenths (14.4) pounds per square inch resulting in a pressure base

of (fourteen and seventy-three hundredths (14.73) pounds per square

inch absolute pressure). One thousand (1,000) cubic feet shall be

denoted as one (1) Mcf.

 

3.2.2 Determination of Gas Temperature

 

The temperature of the gas passing through the meters shall be

determined, continuously by a recording thermometer so installed that

it may properly record the degrees Fahrenheit temperature of the gas

flowing through the meters. The arithmetic averages of the temperature

recorded each day shall be used in computing the measured volume of gas

in Mcf.

 

3.2.3 Determination of Total Heating Value

 

The Total Heating Value of the gas per cubic foot (Btu/cf) shall be

determined by taking the average of the heating values as determined

each day by a chromatograph or the chromatographic analysis of a

collected gas sample, or any other method mutually agreed upon.

 

The average (flow-weighted) heating value of the gas per cubic foot

(Btu/cf) for a unit of time shall be determined by the total Dekatherm

quantity measured divided by the corresponding total volume of gas, in

Mcf, multiplied by 1000.

 

3.2.4 Determination of Specific Gravity

 

The specific gravity of the gas delivered shall be determined by the

use of chromatographic analysis or any other method mutually agreed

upon. Determination of the specific gravity and heating value per

cubic foot (Btu/cf) shall be determined at approximately the same time

or from the same analyzed gas sample.
