**Notes** (1) Boilers produce steam only, but not electricity (2) Gas turbines produce electricity (3) The applicable BART-eligible source category names are: Petroleum refineries; Fossil-fuel boilers greater than 250 MM BTU/hr; sulfuric acid plants; sulfur recovery plants; petroleum storage and transfer facilities, total storage > 300,000 barrels (4) Per HOVENSA, Boiler No 2 is no longer in service (5) Per HOVENSA, Turbines GT 11 and 12 are not fuel combustion devices and therefore have no emissions (one is steam driven, the other is powered by FCC flue gas) (6) 'RFG' means refinery fuel gas; Slurry means No. 6 Fuel oil; LPG means Liquified Petroleum Gas (7) GS13 HRSG (H-3413) is a duct burner. negligible
