for the project management activity x; t CO2‑e / ha / y (see Equations SC1A and SC1B, section 49).
  =  area of carbon estimation area A; ha.
  = project management activity that was being undertaken in carbon estimation area A immediately before the depletion event commenced.
 A = carbon estimation area A as it was when the depletion event commenced, whether or not its boundaries have changed previously.
 (8) The total accumulated carbon sequestration achieved for the relevant carbon estimation area in the period between the project declaration date and the day the depletion event commenced (section 88 or 89) must be calculated using the following formula:
  Equation D2

             Where:
  =  total accumulated carbon sequestration for carbon estimation area A; t CO2‑e.
  =  sequestration value for the project management activity x for carbon estimation area A; t CO2‑e / y.
  =  total (T) period (in years (Y)) since a project management activity was first undertaken on the carbon estimation area until the depletion event was considered to have commenced in accordance with this determination; y.
  = project management activity that was being undertaken in carbon estimation area A immediately before the depletion event commenced.
 A = carbon estimation area A as it was when the depletion event commenced, whether or not its boundaries have changed previously.
Note: Project management activities and carbon estimation areas may have changed across reporting periods. For the purposes of calculating  the project management activity and carbon estimation area is considered to be the same throughout the project as the carbon estimation area that is undergoing the depletion event.
 (9) For the first 7 years following the start of a depletion event in the area, the soil carbon stocks in carbon estimation area A must be calculated using the following formula:
  Equation D3

              Where:
  =  sequestration value for carbon estimation area A in years  since the depletion event (D) commenced; t CO2‑e.
                  Note: cannot be a value less than zero.
  =  total accumulated carbon sequestration for carbon estimation area A; t CO2-e.
 =  period (in years (Y)) that has elapsed since the depletion event (D) first occurred.
 7 =  1/7th is the annual rate of depletion of the soil carbon stocks sequestered in carbon estimation area A.
 A = carbon estimation area A as it was when the depletion event commenced, whether or not its boundaries have changed previously.
 (10) After 7 years of depletion, sequestration levels are taken to reach the levels that they had reached before the commencement of any project management activity in the carbon estimation area (when the total accumulated carbon sequestration, , reaches zero).
 (11) If a depletion event is taken to have stopped under subsection 90(2), sequestration for the carbon
