RE: FMC Westvaco BART Information

Dear Mr. Anderson:

FMC Corporation

·'..V"'.".;.' Iny;.:-;,-.,p]

This correspondence is in response to your questions regarding FMC Westvaco's BART

application for Boilers 6 and 7:

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 Boiler 7. The staggered date for Boiler 7 will allow for a sufficient shakedown period after installation of the errrission reduction equipment later this 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 of Boiler 6 since its modifications in August 2007. The errrissions for both

S02 and NOx have been calculated in terms of lb/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 affect emissions calculated on a rate basis much more than

the identical errrissions calculated on a mass basis.

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 of mass

would be consistent with that endeavor. It would not compromise the program but wo'uld

appropriately reflect the successes in emission reductions from each boiler as a result of

BART.
