9  Fuel loads—coarse fuel and heavy fuel
 (1) This section sets out how to calculate the fuel loads for the project area for a calendar year for coarse fuel and heavy fuel for the definition of FLf,v,s for subsection 7(2).
Outline
 (2) The project proponent must:
 (a) first, calculate the mean fire frequency in vegetation of each vegetation fuel type v in each fire season s for the project area and for the relevant calculation period (see section 5 of this determination), FFv,s, using equation 8, in years–1; and
Note: See section 11 of this Schedule for adjustments to these calculations if some or all of these fire frequencies are equal to zero.
 (b) secondly, using these amounts, calculate the mean fire return interval for each vegetation fuel type v for the project area and for the relevant calculation period, FRIv, using equation 9, in years; and
 (c) thirdly, using the amounts calculated in paragraphs (a) and (b), calculate the mean proportion of fuel size class f that is of vegetation fuel type v that remains after a fire for the project area and for the relevant calculation period, , using equation 10; and
(d)  fourthly, using the amounts calculated in paragraphs (b) and (c), calculate the mean baseline and project fuel load amounts of biomass in the dead organic matter,  and , for fuel size class f of vegetation type v at the mean fire return interval for the project area and for the relevant calculation period, in tonnes of biomass per hectare, using equation 11; and
 (e) finally, using the amounts calculated in paragraph (d), calculate the baseline and project fuel loads, FLf,v,s, in tonnes of biomass per hectare in accordance with equation 12 for the calendar year for the project area.
Calculations
 (3) For paragraph (2)(a), the equation is the following:

  equation 8

  where:
n is length, in years, of the relevant calculation period in relation to which  or  is being calculated.
y is a calendar year of the relevant calculation period.
SFS,v,s,y is the fire scar area, in hectares, for vegetation fuel type v for fire season s of year y of the relevant calculation period for the project area, and has the same value as SFS,v,s as calculated for that year referred to in subsection 7(1).
SV,v is the total area covered by vegetation of vegetation fuel type v in the project area, ascertained from the vegetation fuel type map for the project area, in hectares.
 (4) For paragraph (2)(b), the equation is the following:

  equation 9

  where:
s is a fire season (either the early dry season or the late dry season).
FFv,s is the mean fire frequency in vegetation of vegetation fuel type
