the 30-x cm layer which then requires the 30-x cm layer to be included in accounting to prevent over crediting.
           (c)    if Divisions 4 and 5 of this Schedule are applied to the 0-x cm layer of the estimation for the CEA—the change in organic in soil organic carbon stock for a CEA for equation 116 is deemed to be the value for the 0-x cm layer, not the 0-30 cm layer.
Note: Crediting is based on the whole soil profile (0-x cm layer). However, crediting can be based on only the 0-30 cm layer if permitted by this section. Results of the 30-x cm layer contribute to crediting once changes are observed in the layer. Reporting of results in the 0-30 cm layer is required, even if it does not impact crediting, to inform the national inventory.
 (3)  For the purposes of subparagraph (2)(b)(iii), the change in soil organic carbon stock in the 30-x cm layer for a reporting period is taken to be negative if the change in that layer   worked out in accordance with the following equation has a value less than 0:
  equation 70

where:
        is the change in soil organic carbon stock for the CEA for the reporting period between the first estimation event t0 for the CEA and the last estimation event tx for the CEA in the reporting period, for the 0-x cm layer, worked out using equation 113.
        is the standard error of the mean difference (the ) between total soil organic carbon stock for the CEA between the first estimation event t0 for the CEA and the last estimation event tx for the CEA in the reporting period, in tonnes of soil organic carbon, for the 0-x cm layer, worked out using equation 114.

        is the value of the quantile function (inverse distribution function) for the t-distribution with the value for alpha () set out in the Supplement and the value for the degrees of freedom,  for the 0-x cm layer worked out using equation 115.
Note: The value should be negative.
        is the change in soil organic carbon stock for the CEA for the reporting period between the first estimation event t0 for the CEA and the last estimation event tx for the CEA in the reporting period, for the 0-30 cm layer, worked out using equation 113.
        is the standard error of the mean difference (the ) between total soil organic carbon stock for the CEA between the first estimation event t0 for the CEA and the last estimation event tx for the CEA in the reporting period, in tonnes of soil organic carbon, for the 0-30 cm layer, worked out using equation 114
 is the value of the
