Unless Following notification pursuant to section 2.11, unless the Interconnected Party can reasonably assurereasonably demonstrate to First Gas that those suchthose low Gas injection rates were willwere extraordinary occurrences and that are unlikely not expected to occur againto the same extent again then, without limiting its other rights or remedies, , and/or that the Metering is Accurate even at those low injection rates, flows: First Gas may require give notice to the Interconnected Party at its cost to requiring that it modify the Metering be modified to improve the Accuracy of metered quantities ensure that it is Accurate at lowerthose low flow rates, and: whereupon ; and the Interconnected Party shall then procure that the Metering Owner carries out thethen implement appropriate modifications at its cost as soon as practicable.

Direct Gas Measurement Only Metering shall determine Gas quantities by direct measurement only and not by difference or by other indirect means. Testing of Metering and Provision of Information The Metering Owner shall use reasonable endeavours, including by means of periodic testing in accordance with the Metering Requirements, to ensure that Metering is Accurate. The other Party may request, and the Metering Owner shall then provide: reasonable technical information relating to the Metering at a Receipt Point; a copy of its planned maintenance schedules relating to any Metering; and the results of any testing of any Metering. In relation to any new Metering, the Metering Owner shall: no earlier moreearlier than 3 Months before that Metering is installed or placed into serviceservice (whichever is later),, test each custody transfer meter and other gas measurement device forming part of that Metering; and where the Metering includes a verification meter, conduct an in-situ verification test of each custody transfer meter as soon as practicable after that itthe Metering is placed into service, subject each meter and other gas measurement device to an in-situ verification test, to ensure that the each such meter and gas measurement devicethe Metering is Accurate. If the any meter or gas measurement devicethe Metering is found to be Inaccurate, the it shall be serviced, repaired, re-calibrated or replacedthe Metering Owner will service, repair, re-calibrate or replace it, then re-test testedtest it to establish that it is Accurate. The Metering Owner will shallwill provide the other Party with written evidence of testing pursuant to this section 4.43.3 that demonstrates each meter and other gas measurement device is Accurate.. The Metering Owner shall use all reasonable endeavours, including by means of periodic testing in accordance with the Metering Requirements, to ensure that each meter and other gas measurement device Metering is Accurate. The other Party shall be entitled tomay request, and the Metering Owner shall then provide: reasonable technical information relating to the Metering; a copy of the planned maintenance schedules relating to the Metering; and the results of any testing of the Metering.
