GENERAL TERMS AND CONDITIONS

 

Measuring Equipment Out of Repair. If, for any reason, any

measuring equipment is out of service or out of repair so that

the quantity of gas delivered is not correctly indicated by the

reading thereof, the gas delivered during such period shall be

estimated by the parties on the basis of the best data available

using the first of the following methods which is feasible:

 

a) By using the registration of any check measuring equipment

installed and accurately registering; or

 

b) By correcting the error if the percentage of error is

ascertainable by calibration, test or mathematical

calculations; or

 

c) By estimating the quantity of delivery by deliveries during a

preceding period under similar conditions when the meter was

registering accurately.

 

Adjustment of Inaccuracies. If any meter is found to be

inoperative or inaccurate, it shall be adjusted to register

correctly. The amount of error shall be determined by the most

accurate method found feasible, and, if the error shall have

resulted in an error of more than two percent (2%) in the

measurement of gas delivered, then the calculated deliveries of

gas through such meter shall be accurately adjusted to compensate

for such error. Such adjustment shall be made for such period of

inaccuracy as may be definitely known, or if not known, then for

one-half the period since the date of the last meter test.

Measurement data corrections must be processed within six (6)

months of the production month with a three (3) month rebuttal

period. This time limitation will not apply in the case of

deliberate omission or misrepresentation or mutual mistake of

fact. Also, the parties' other statutory or contractual rights

shall not otherwise be diminished by this provision. A meter

adjustment or correction becomes a prior period adjustment after

the fifth business day following the production month. Any

measurement prior period adjustments are taken back to the

production month.

 

3. MERCHANTABLE GAS

----------------

 

Natural gas delivered by Northern to a Shipper shall be merchantable

natural gas. Upon request, Northern will offer to negotiate with a

Delivery Point Operator, on a not unduly discriminatory basis, how

Northern will manage the quality of gas delivered to the Delivery

Point Operator. The quality of gas delivered to other Shippers

on the pipeline will not be degraded by the negotiation of gas quality

management at delivery points.
