42  Baseline for the methane component of coal mine waste gas sent to flaring or flameless oxidation devices
 (1) The baseline for the methane component of coal mine waste gas sent to flaring or flameless oxidation devices for the project during time interval t, in cubic meters, is worked out using the formula (equation 37):
where:
BCH4,Fl means the baseline for the methane component of coal mine waste gas sent to flaring or flameless oxidation devices for the project during time interval t, in cubic meters.
QFl,Cap,m means the recognised capacity of device m during time interval t, in cubic metres, worked out at the application time in accordance with subsection (3).
AFFl,m means the annual availability factor of device m which, subject to subsection (4), has:
 (a) the value calculated in accordance with the standard maintenance cycle specified by the manufacturer; or
 (b) the default value of 1.
m means an existing flaring or flameless oxidation device.
 (2) The summation over m is to be performed over all existing flaring or flameless oxidation devices at the point of the highest total recognised capacity of all of the existing devices in the period between 24 April 2014 and the application time.
Note: The summation over m results in a fixed quantity and is the same for all equal time intervals.
 (3) The recognised capacity of device m during time interval t is calculated by:
 (a) multiplying the manufacturer's specifications for the maximum energy released per unit time by the time interval in appropriate units, with the result expressed in gigajoules; and
 (b) converting the result of paragraph (a) to cubic metres by multiplying it by the factor 37.7x10‑3 gigajoules per cubic metre.
 (4) The same value of AFFl,m must be used for that parameter for all time intervals in all reporting periods.
