recovery boilers are firing low sulfur oil. The potential operating scenario shows the amount 

of high sulfur fuel oil that can be burned in No. 1 Recovery Boiler in order to meet its SO2 

PSD limit. The low sulfur fuel oil limit necessary for the No. 9 Recovery Boiler BART 

exemption was based on a short term hourly rate if the boiler was on fuel oil for 24 hours, 

which may occur on occasion; however, this does not correlate to an annual limit because 

the main function of the recovery boiler is not to bum fuel oil all of the time. The last ten 

years of fuel oil burning in No. 9 Recovery Boiler is included to determine the highest 

volume of fuel oil burned in one year. Also note that over the last 10 years the highest 

actual fuel oil burning year on No. 1 Recovery Boiler is also less than the value used in the 

calculations. 

Analysis Assumptions 

1) All fuel oil burned in the recovery boilers was during startup or shutdown conditions 

2) All fuel oil burned in No. 9 Recovery Boiler is low sulfur No. 6 fuel oil 

3) When either recovery boiler was on low sulfur No. 6 fuel oil all three sources were 

burning that same oil. 

4) Low sulfur fuel oil = 0.5% sulfur 

5) High sulfur fuel oil = 2.1% sulfur 

6) SO2 emission factor = 157s (AP-42, Fifth Edition, Volume I, Chapter 1, External 

Combustion Sources, Table 1.3-1) 

7) The last 12 month fuel oil pricing was used to determine an average fuel oil cost 

8) SO2 emissions in the lime kilns are reduced by 98.6% 

Using these assumptions, changing from high sulfur No. 6 fuel oil to low sulfur No. 6 oil in 

the No. 1 Recovery Boiler will cost $7,463 per ton of SO2 emissions removed based on the 

actual operating scenario and $3,359 per ton of SO2 emissions removed on a potential 

operating scenario. Both scenarios are above the $2,000 per ton SO2 emissions removed 

required to implement the change. 

Other possible fuel switches include No. 2 fuel oil, which is more expensive (-$2.45 per 

gallon) and would generate the same SO2 emissions as low sulfur No. 6 fuel oil. It would 

also require minor equipmentloperating modifications. Natural gas is a possible fuel, which 

is also more expensive than high sulfur No. 6 fuel oil (-$8.1 l/MMBtu vs. -$7.93/MMBtu) 

but currently cheaper than low sulfur No. 6 fuel oil (-$8.11/MMBtu vs. -$8.53/MMBtu). 

Natural gas prices have been highly variable over the past several years. Current costs 

would not necessarily be sustainable. Furthermore, the recovery boilers are not equipped to 

bum natural gas and would require extensive equipment changes. The natural gas option is 

assumed to be a high cost option due to fuel cost uncertainty and equipment modifications.

At this time no other SO2 controls are technically feasible on a recovery boiler. Furthermore, 

the fuel oil switch required for the BART exemption on No. 9 Recovery Boiler significantly 

reduces (46.4%) the SO2 emissions that are in the VISTAS emissions inventory for 2002 and 

2018. This reduction alone may drop the MeadWestvaco facility out of the area of influence 

(AOI). 

BART = 1,450 TPY 

VISTAS 2002 = 2,3 15 TPY 

VISTAS 201 8 = 2,706 TPY
