Subject: 	 Best Available Retrofit Technology (BART) Waiver 


Tulsa Refinery 


Dear Mr. Moyer: 

The Oklahoma Department of Environmental Quality (ODEQ) received a.BART waiver 

request for the referenced site on December 5, 2006. 

After the technical review, the ODEQ is approving a waiver for the Tulsa Refinery. This 


. waiver is based on facility BART sources which are not expected to cause or contribute 


. to visibility impacts at Class I areas based on submitted modeling. 


While ODEQ has approved the waiver, the waiver is subject to EPA and public comment 

during the Regional Haze State Implementation Program (SIP) approval pro~ess. 

Thank you for your cooperation in this matter. If we may be of further service, please 

contact Phillip Fielder (405) 702~4100. 71; .. Dawso~~-""Jhi""'~-e-f-E-n-g~i~eer AIR QUALITY DIVISION

EUGIO Sulfur Recovery Unit 

. Scrubbed tail gas exhausts at 3,600 ACFM and 340°F through a 2' diameter stack at 200'. 

above grade; The unit was constructed in 1972. 

The refinery used an emission factor of 278 pounds of S02 per ton of sulfur produced, 

taken from Table 8.13':1 of AP-42 (1195), coupled with a scrubber .efficiency of 98.5%. 

Assuming 8760 hours of production at a rate of 18 tons per day yields 18 TPD x 365 

days/year x 278lb/ton x (1 0.985) x ton/2000lb = 13.70 TPY or 3.13lblhr. 

EUG12 Flares 

The #2 flare tip was designed for smokeless operation at 120,000 lblhr of 87 average 

molecular weight gas and 42,000 lblhr of steam and has a maximum capacity of 352,600 

lblhr of 67.8 average molecular weight gas. Both flare tips have a diameter of 5'.

Cooling towers are considered to be trivial sources for Title V purposes, because . 

particulate emissions are . larger than 30 microns. 'Entrained VOCs and chlorine are 

inc1uded'inthe tables for EUG 16 above, inthe row titled "Water." Calculation ofVOC 

is based .on factors found in Table 5.1-2 of AP-42 (1/95), using a circulation rate of 

89,940 gpm. Chlorine has a concentration of 7 ppm and drift is assumed to be 1.7 

Ib/1 000 gal in this induced draft system. '.
