## This spreadsheet is intended to display "major sources" of Sulfur Dioxide (SO2) Emissions located in the three RH 309 states as projected for Calendar Year 2018 It is broken down into 3 subgroups: 1) Existing Electrical Generating Units (EGU's) 2) Permitted or Future Electrical Generating Units (EGU's) ... & ... 3) Other Industrial Point Sources (Non-EGU's)

**EGU's** The **Me thodology** for projecting **existing EGU's**into the future involves the following steps: 1) the electricity

production (MW's) for each individual unit at a plant was determined from the Energy Information Administration [EIA] (data available for 2002-05) 2) the electricity

generation design maximum capacity (MW's) was determined for each individual unit from EIA data 3) an operating Capacity Factor was determined by dividing the year specific production by the design maximum capacity of the each individual plant unit 4) all individual units were assumed to be operating at 85% capacity in 2018 (unless they

were already

operating above this level) 5) the Growth Ratio necessary to achieve 85% capacity was determined by

dividing 0.85 by

the Capacity

Factor for each individual plant unit from Step 3 (averaged over four years) 6) a Current Year Emission Factor (lb SO2/MM Btu) was calculated for the latest year of available EIA data (2006), using the actual reported emissions (tons SO2) for each individual plant unit divided by the actual reported annual heat generation (MM Btu) 7) the 2018 Emission Factor was assumed for sources which were thought to be Subject to BART at presumptive levels of 0.15 lb SO2/MM Btu (BART determinations were not finalized in most cases; Utah Hunter & Huntington BART levels were known at 0.12 lb SO2/MM Btu) 8) the 2018 Emission Rate (tons SO2) was calculated by multiplying current year emissions by the ratio of the 2018 to current year Emission Factors 9) the Adjusted 2018 Emission Rate (tons SO2) was "grown" to 85% capacity by multiplying the 2018 Em ission Rate by the Growth Ratio from Step 5 (emissions from units already operating at or higher than the 85% capacity in the 2002 data year, were not grown, but accepted at face value)

**Non-EGU's**

The **Me thodology** for projecting emissions from **"Other Industrial Sources"**is described in Pechan's October 2006 dated FINAL "2018 SO2 Emissions Evaluation for Non-Utility Sources" Report located on the "Stationary /Area Source Emissions Projections" link from the Stationary Sources Joint Forum Page of the W RAP website: http://www.wrapair.org/forums/ssjf/documents/eictts/projections.html
The SO2 emissions for 19 Natural Gas Processing Plants were updated by Environ in 2007, with additional research into future O&G Operations. The September '07 FINAL Report with the results of of that update is located on the "Oil/Gas Area Source Emissions/Controls" link from the Stationary Source Joint Forum Page of the WRAP website: http://www.wrapair.org/forums/ssjf/documents/eictts/oilgas.html
The 2005 SO2 Milestone Report had some sources which were not picked up in the Pechan report. In those cases, the 2005 emissions were used as a placeholder for the 2018 emission values.
