GENERAL TERMS AND CONDITIONS

 

 

17. MEASUREMENT AND MEASURING EQUIPMENT (Cont'd)

 

elapsed since the date of the last equipment test, to a maximum of

fifteen (15) days or back to 7:00 a.m. on the first day of the current

month, whichever is less.

 

All claims of either party that measurement is in error, for any reason,

as to the gas received and/or delivered must be submitted in writing by

such party to the other party within three hundred sixty five (365) days

from the date of the invoice in which the error is claimed to have

occurred for all invoices issued on or after July 1, 1995 or else such

claim shall be deemed to have been waived by the aggrieved party.

Adjustments for such claims shall be limited to a period of three

hundred sixty five (365) days.

 

WNG and Shipper shall design, install, operate and maintain their

respective measurement equipment in such a manner that pulsation induced

measurement error is minimized. Pulsation induced error shall not

exceed one quarter of one percent (0.25%) of square root error (SRE).

Equipment may be used to determine SRE if agreed upon by both parties.

WNG shall have the right to request a test of the meter facility of

Shipper, and Shipper shall have the right to request a test of the meter

facility of WNG at reasonable intervals, no more often than once in

thirty days. If SRE is found to exceed the limit stated above, the

party owning the orifice meter shall, at the request of the other party,

submit to the requesting party plans for installation of pulsation

suppression equipment within a thirty-day period following such request,

and shall install said equipment within a reasonable period of time. If

such plan is not submitted within the thirty-day period, or equipment

not installed within a reasonable time, the requesting party shall have

the option of shutting in the delivery. Pulsation errors determined by

use of the square root error indicator (SREI) manufactured under a

license from the Southern Gas Association are to be used only for the

purpose of indicating needed facility modification and are not to be

used for adjusting accounts.

 

Shippers, operators or producers shall use their best efforts to avoid

any equipment, including intermitters or timed motor-operated or

gas-operated valves, the use of which prevents WNG's metering equipment

from obtaining reliable measurements. If such equipment is required in

order for a well to produce, WNG will cooperate with the producer to

reach a mutually acceptable method of accounting for any interference

with measurement caused by the equipment.
