                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              Frequency—in accordance with the NGER (Measurement) Determination

QCH4,h, QCH4,i, QCH4,k  ,QCH4,l, QCH4,h,t or QCH4,m,t
 (2) To estimate QCH4,h (if worked out using an integrated monitoring system), QCH4,i (if worked out using an integrated monitoring system), QCH4,k  (if worked out using an integrated monitoring system), QCH4,l (if worked out using an integrated monitoring system), QCH4,h,t or QCH4,m,t the project proponent must use:
 (a) a flow computer to estimate the volume of coal mine waste gas sent to device h, m, k or l; and
 (b) either of the following to measure the methane component of coal mine waste gas sent to device h, m, k or l;
 (i) a gas chromatograph;
 (ii) a gas analyser; and
 (c) the standard conditions defined in subsection 2.32(7) of the NGER (Measurement) Determination.
 (3) However, if a gas analyser is used:
 (a) the maximum upper bound percentage uncertainty, expressed as a decimal fraction (Uh), associated with the measurement of the fraction of the volume of coal mine waste gas that is methane that is sent to each device h must be calculated according to standard methods; and
 (b) the quantity of methane is adjusted by multiplying QCH4,h, QCH4,i, QCH4,k, QCH4,l, QCH4,h,t or QCH4,m,t by the factor (1‑Uh).

Oh,t (or Om,t)
 (4) Subject to subsections (5) and (6), the project proponent may use one of the following methods to measure whether flaring device h (or m) is operating in time interval t:
 (a) temperature measurement;
 (b) a UV detection sensor coupled to a flare management system;
 (c) another internationally recognised apparatus for monitoring the operation of a flaring device.
 (5) If temperature measurement is used, then the flaring device is taken not to be operating in a time interval if:
 (a) there is no record of the temperature of the exhaust gas of the flare for the time interval; or
 (b) the recorded temperature is less than 500°C for any period in the time interval.
 (6) If a UV detection sensor or another internationally recognised apparatus is used, then the flaring device is taken not to be operating in a time interval if:
 (a) there is no record
