This message has been forwarded. Good Afternoon Conrad, 05/09/2012 12:06 PM

In response to yourquestion regarding the addition ofcarbon to the electrodes. We add electrode paste, which is comprised ofcarbon, to the existing electrodes
.We consume the electrodes as part of the smelting process. We have a paste crewthat adds casing and paste to each electrode on each furnace on a as needed basis
. This paste is at ambienttemperature when it is added to the electrode. As part ofthe smelting process the electrodes are being slipped (lowered} intothe molten metal. As each electrode is being slipped the electrode progresses through several temperature zones ( baking zones) and is eventually consumed. Any emissions generated from the consumption ofthe electrodes would be captured atthe furnace roofand these emissions would be evacuated to the baghouse
. So to summarize this answerto your question, adding paste to the electrode does not contribute to any emissions outside ofthe capture zone atthe furnace. DuringJames Hagedorn'svisit tothe Felman facility some fugitive emissions from the facility where observed. The fugitive emissions I believed James was referring to was when the slag from a recent tap at numberseven (7) furnace was being raked off. Some fugitives did escape the building duringthe rake-off. As we discussed, this is one ofthe five local ventilation capture processes we are currently addressing
. Ifhope this explanation answered your question. Ifyou need any additional information please contact me. Thanks Rich Lunn From: Conrad Chin [mailto:Chin.Conrad@epamail.epa.gov]

Good morning Rich and ShawnThankyou for sending outthe invitation for tomorrow's call. Ijust got offthe phone with Jim Hagedorn at our Region 3 office
. I had invited Jim to participate in the call, but unfortunately he will not be able to. Jim informed me he visited your facility in March this year, and observed some high opacity readings from the melt shop while he was there.One specific example was afterthe addition ofcarbon to the electrodes, he observed a spike in opacity. Could we spend sometime in discussing this (and other processes that maycause opacityto spike)? Thanks. Conrad
