General Terms and Conditions

11.5 Calibration and Testing of Meters. The accuracy of Transporter's measuring

equipment shall be verified by Transporter at reasonable intervals, and if

requested, in the presence of representatives of Shipper, but Transporter shall

not be required to verify the accuracy of such equipment more frequently than

once in any 30 day period. In the event either party shall notify the other that

it desires a special test of any measuring equipment the parties shall cooperate

to secure a prompt verification of the accuracy of such equipment. The expense of

any such special test, if called for, shall be borne by Shipper if the measuring

equipment tested is found not to be in error by more than two percent.

If, upon testing, any measuring equipment, including recording calorimeters, is

found to be in error by not more than two percent, previous recording of such

equipment shall be considered accurate in computing deliveries of Gas, but such

equipment shall be adjusted at once to record accurately as defined by the

appropriate metering standards.

If, upon testing, any measuring equipment shall be found to be inaccurate by an

amount exceeding two percent, at a recording corresponding to the average hourly

rate of flow for the period since the last preceding test, then any previous

recordings of such equipment shall be corrected to zero error for any period

which is known definitely but in case the period is not known or agreed upon,

such correction shall be for a period extending over one-half of the time elapsed

since the date of last test, not to exceed a period of 180 days.

11.6 Measurement Corrections.

(a) Measurement data corrections should be processed within six (6) Months of

the production Month, with a three (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 will not otherwise be diminished by this standard.

(b) 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.

11.7 Correction of Metering Errors - Failure of Meters. In the event a meter is out

of service, or registering inaccurately, the volume of Gas delivered shall be

determined:

(a) by using the registration of any check meter or meters, if installed and

accurately registering; or, in the absence of (a);

(b) by correcting the error if the percentage of error is ascertainable by

calibration, tests, or mathematical calculation; or in the absence of both

(a) and (b), then;

(c) by estimating the quantity of delivery by deliveries during periods under

similar conditions when the meter was registering accurately.

11.8 Preservation of Metering Records. Transporter and Shipper shall each preserve

for a period of one Year all test data, charts and other similar records created

after June 1, 1996.
