19  Re‑routed gas quantity
 (1) The re‑routed gas quantity in relation to a flare device in a reporting period is the total of the gas quantities (the relevant gas quantities), in tonnes, worked out in accordance with this section in relation to particular periods (relevant periods) within the reporting period.

Process venting emissions
 (2) If any of the gas passing through the flare device in a relevant period consists of process venting emissions, the relevant gas quantity for the relevant period is to be measured, in tonnes, in accordance with the monitoring requirements (other than section 33).

Fugitive leak emissions
 (3) If all of the gas passing through the flare device in a relevant period consists of fugitive leak emissions, the relevant gas quantity for the relevant period is:
 (a) if the flare device is continuously monitored during the relevant period in accordance with the monitoring requirements (other than section 33)—the gas quantity recorded as a result of that monitoring; or
 (b) if paragraph (a) does not apply, and there is a fugitive leak measurement period for the flare device that ends before the start of the relevant period—the amount worked out using equation 6; or
 (c) if neither paragraph (a) nor (b) applies—zero.
 (4) The relevant gas quantity in relation to flare device i in a relevant period, in tonnes, for a case where paragraph (3)(b) applies, is worked out using the formula (equation 6):
where:
QO,i means the relevant gas quantity in relation to flare device i in the relevant period, in tonnes.
TO,i means the duration of the relevant period, in hours.
QM,i means the gas quantity passing through flare device i in the fugitive leak measurement period for flare device i, in tonnes, measured in accordance with the monitoring requirements.
TM,i means the duration of the fugitive leak measurement period for flare device i, in hours.

Disregard periods that are not monitored operating periods
 (5) A period is to be disregarded for the purposes of working out a gas quantity, or the duration of a relevant period, in relation to a flare device under this section if the period is not a monitored operating period for the flare device.
