through a solid scrubber. There is a seal liquid system on the vacuum pumps that generates 3 to 4 gallons an
hour of water that is a seal fluid but its under very high vacuum.
Commissioner Robertson: So the offgases........
Jay M. Bailey: The off gases are scrubbed. They are absorbed on carbon.
Commissioner Robertson: Are there any plans for lob facilities on site to make sure that the process is
running as designed. -7
Phil McLain: Yes, we are talking about doing that. There are certain things that we can do in a small amount
and until we get the lab there we can hire out There are labs locally that we can use, because we have to
produce an A5TM fuel.
Commissioner Robertson: The process that has animal fats has higher free -fatty acids and it usually means
you have to remove a lot more water. The ion exchange still can handle the process at that point.
Jay M. Bailey: Yes, it can.
Commissioner Robertson: So no matter what your feed stock is, we don't have a waste water issue as for as
big septic tanks or pump trucks.
Jay M. Bailey: It would be a material that would be pump and hauled. It will have to be characterized
because I'm sure we would talk to the Statesville sewer district about possible discharge there, but it's a pump
and haul situation.
Commissioner Robertson. I'd gotten a letter from someone and they'd asked about the sulfuric acid and the
process The only place I could find that in the literature was that it was used in the neutralizer Do you have
that in the process?
Raymond Odom: We typically use glacial acidic acid which is strong vinegar.,... basic quenching and killing the
process and neutralizing the salt.
Commissioner Robertson: And thou all recovered in the ion exchange?
Raymond Odom: Yes, that's allgone in the reaction system.
Commissioner Williams: Do you have documentation that Statesville will accept the wastewater?
Raymond Odom: No sir, we haven't approached that point of the operation yet. That would be with the
permitting process with DEAR and the natural resources and aquifers. We haven't gone through that process
yet
Phil McLain: It's dependent upon the size of the waste water.
Raymond Odom: The waste water in the system is basically the one to fourgallons an hour out of the cooling
system. The reaction is basic - all of the water consumed within the process If we use a catalyst, its a 30%
sodium metho/ate methoxide catalyst -- there is no reaction water. A little bit of water. If anyone is familiar
with parts per million - 20 hundred parts per million is a lot of water. five hundred parts per million is very
little BBs in a big boxcar.
Commissioner Williams: I believe this board moved on a process where the some question come up about waste
water disposal. The same response was that it would be entered into the Statesville system. Suppose they
won't accept it Even though it may only be 55gallons Where is it going?
Raymond Odan: : Well then it would have to be addressed with Mr. McLain (inaudible) wants to haul it off as
typically as a t ox in a Hasway system somewhere.
4moussio ner Robertson: Do you know where the waste in Caldwell Countygoes?
Raymond Odom: Nb I do not. But to address the water issue -- when the permitting process occurs we will
have to approach the City of Statesville or the County of Iredell to see if they would accept the waste. If
not, then other options would have to be pursued
Commissioner Williams: You would have to have that in order before it could be permitted
