Mean Average (MA): 0.2070 Standard Deviation (SD): 0.1285 SD as a % of MA 62 The 1/09, 2/09, and 1/10 values are adjusted from Domtar’s official emissions records to include consideration of the 97.5 % control efficiency on SO2 emissions from fuel oil combustion provided by the WESP. The consideration was not applied in the official records until 2011. Only three months are adjusted because those are the only months in 2009 and 2010 during which fuel oil was combusted.

## `This spreadsheet is intended to calculated SO2 emissions for PB1 and PB3, from the combined fuels

of bark, TDF and cubes. These emission calculations take into account the SO2 removal efficiency of the ash from wood combustion, based on Someshwar and Jain, 1993 from TAPPI Journal Vol. 76, No. 7. SO2 calculations are based on equation 6 from Table 3 in Someshwar and Jain, 1993. Equation 6 was chosen because it was a conservative estimate of the removal efficiency and included a summary of a mixture of different fuel types that seemed most representative of the fuels in PB1 and PB3.
Fuel oil SO2 emissions are not calculated here, but space is provided to link to fuel oil SO2 emissions in order to summarize total SO2 emissions from PB1 and PB3 on this spreadsheet.
Cells with yellow highlight and blue text are intended for data input. Each month the usage of each of the combined fuels should be entered in the yellow area including bark (wet basis), TDF and cubes. SO2 emissions from fuel oil are calculated separately based on specific permit conditions. These emissions can be included in this table by link or by entering them each month. A running total is available for each applicable column.
Parameters such as sulfur content of the fuels and moisture content of the bark are listed at the top of the table. These parameters can be changed as necessary, but in general should not need to be edited.
