1. The BART Process by Kathy Kaufman and Joe Kordzi September 1, 2005 EPA Region 6

2. Applicability  The CAA requires use of the BART Guidelines for powerplants 750 MW or greater.  States are encouraged to use the BART Guidelines for all source categories.

9. Part 1 - Identify the BART-eligible Sources Example: A stationary source has two emissions units, with the following potential emissions: Emissions unit A Emissions unit B 200 tpy SO2 100 tpy SO2 150 tpy NOX 75 tpy NOX 25 tpy PM 10 tpy PM Potential emissions of SO2 are 300 tpy, which exceeds the 250 tpy threshold. Therefore, the entire source is BART-eligible, even though the potential emissions of PM and NOX at each emissions unit are less than 250 tpy each.

25. Part 3 – Determine the BART Controls

26. Presumptive controls for >200 MW EGUs SO2: 95 % control or 0.15 lbs/MMBtu. NOx: In NOx SIP call area, extend use of controls to year-round. Outside NOx SIP call area, current combustion controls 0.2 – 0.45 lbs/MMBtu, depending on coal and boiler type

27. Presumptive NOx emission limits Dry-bottom wall-fired (75 units subject to presumptive limits) Bituminous 0.39 Sub-bituminous 0.23 Lignite 0.29 Tangential-fired (110 units subject to presumptive limits) Bituminous 0.28 Sub-bituminous 0.15 Lignite 0.17 Cell Burners (27 units subject to presumptive limits) Bituminous 0.40 Sub-bituminous 0.45 Dry-turbo-fired (4 units subject to presumptive limits) Bituminous 0.32 Sub-bituminous 0.23 Wet-bottom tangential-fired (3 units subject to presumptive limits) Bituminous 0.62
