2. MEASUREMENT

2.1 Unit of Measurement and Metering Base - The volumetric measurement

base 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.

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. (Estimate

missing or late measurement data and treat actual as prior period

adjustment, with the measuring party to provide the

estimate.)(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).

2.2 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

that Transporter has direct custody transfer responsibilities over,

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.
