### This correspondence is in response to your questions regarding FMC Westvaco's BART applicationforBoilers 6 and7:

1. 

### The CUlTent carbon monoxide (CO) lirrrit of 0.29 lb/MMBTU for each boiler will continue to be an attainable limit despite the reduction in NOx from 0.39 to 0.35 lb/MMBTU.

2. FMC proposes an effective date for BART compliance of 0110112009 

### for Boiler 6 and 07/0112009

### for Boiler7. The staggereddate forBoiler7 will allow for a sufficientshakedown period afterinstallationoftheerrrissionreductionequipmentlaterthis year.

3. FMC encourages the Division to continue considering emission limits on a mass basis (lb/hr) 

### as opposed to a rate basis (lb/MMBTU). 

### I have attached a table indicating the performance ofBoiler 6 since its modifications in August 2007. The errrissions for both S02 and NOx 

### have been calculated in terms oflb/MMBTU and lblhr on 30-day rolling averages. It 

### becomes very clear that variations in steam demand, which deterrrrine the boiler's firing rate, negatively affectemissions calculatedon a 

### rate basis muchmore than the identicalerrrissions calculatedon a

### massbasis.

The 

### goal of BART is to improve visibility in Class I areas by reducing the 

### mass emissions linked to visibility deterioration. Establishing emission lirrrits in terms ofmass wouldbe consistent with thatendeavor. It

### wouldnot compromise the programbutwo'uld appropriately reflect the successes in emission reductions from each boiler as aresult of BART.
