GENERAL TERMS AND CONDITIONS

2. MEASUREMENT

2.1 Unit of Measurement and Metering Base. The Volumetric measurement

based shall be 1 cubic foot of gas at a pressure base of 14.73

pounds per square inch absolute, at a temperature base of 60 degrees

Fahrenheit, and without adjustment for water vapor.

2.2 The cutoff for closing measurement is five Business Days after the

business Month (NAESB WGQ Standard 2.3.7). Measurement data that is

missing or late at the cutoff is to be estimated pursuant to NAESB

WGQ Standard 2.3.13. For treatment of measurement prior period

adjustments, treat the adjustment by taking it back to the

production Month. A meter adjustment becomes a prior period

adjustment after the fifth Business Day following the business Month

(NAESB WGQ Standard 2.3.11). For reporting measurement prior period

adjustments, report it with the restated line item with the new

total quantity for the Day and Month (NAESB WGQ Standard 2.3.12).

Measurement data corrections shall be performed pursuant to NAESB

WGQ Standard 2.3.14. Measurement data corrections should be

processed within 6 Months of the production Month with a 3-Month

rebuttal period. This standard shall not apply in the case of

deliberate omission or misrepresentation or mutual mistake of fact.

Parties' other statutory or contractual rights shall not otherwise

be diminished by this standard (NAESB WGQ Standard 2.3.14). This 3-

Month rebuttal period shall begin with the interested party issuing

a written notification that a measurement dispute exists. These

disputes will apply to measurement errors that involve quantities

for which Transporter has direct custody transfer responsibilities,

as well as volumes measured by other companies that have been

audited by Transporter.

2.3 Measurement data available upstream of aggregated points should be

sent to the allocating party and used to allocate the aggregated

volume back to the upstream points (NAESB WGQ Standard 2.3.8).

2.4 Transporter's measurement information provided via electronic

delivery mechanism (EDM) shall conform to the requirements of the

Data Dictionary standards as set forth in NAESB WGQ Standards 2.4.4

and 2.4.5.
