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.
