Table 3.3.1 for i202 and Table3.2.3 for i203This form is to be used by sources that have emitted 100 tons or more of SOxin any calendar year after 1999, and that arenot subjectto acid rain continuous monitoring reportingrequirements (40CFR Part 75). Row 1 in the following table(s) contains historical inventory data for the listed component. Row 2 is used to calculate the2006 process emissions using the samemethod that was used in the historical data. The inputs required are in green font. To insert the newdata you type over the top of the old data. Row 3 (shaded) is used to show and calculateany changes in the method of calculation from 1998to 2006 (i.g. emission factors, % of sulfur, heating value, controls, breakdowns, estimation methods).If the current method of calculatingthe SOxemissions does not work with the equation providedin row 3, the calculation should be provided in therow 4. Rows 3 and 4 should have the same calculations as contained in the 2006Emission Inventory.Emissions (TPY) = (Total Size MMBtu/hr) * (Annual Use hrs) * (EmissionFactor) / (2000lb/ton)Emission Factors from AP-42 (5th Ed.)
