45  Volume of methane vented due to a major venting event

  If a major venting event associated with an anaerobic digester occurs during a reporting period, the volume of methane vented due to the major venting event, in cubic metres, is worked out using the formula (equation 20):

MVent,q means the volume of methane vented due to major venting event q, in cubic metres.

MSBCS means the maximum biogas storage capacity of the anaerobic digester, in cubic metres, worked out in accordance with the monitoring requirements.

FRq means the average total daily flow of biogas from the anaerobic digester for the 7 days before major venting event q, in cubic metres per day, worked out in accordance with the monitoring requirements.

tq means the number of days for all or part of which major venting event q is uncontrolled, worked out in accordance with the monitoring requirements.

WBG,CH4 means:

 (a) if this parameter is, or is required to be, monitored continuously—the fraction worked out in accordance with the monitoring requirements; or

 (b) otherwise—the fraction mentioned in subsection 5.37(2) of the NGER (Measurement) Determination.

q means a major venting event associated with the anaerobic digester.
