Chun Yi, I think these are
certainly emissions that fall within the scope of our target list and so we should
take what steps are necessary to include them. It seems to me there are two
ways to go about this: -convert these
emission factors to total PCBs and estimate emissions on that basis -include the
appropriate pollutant codes and map them to total PCBs for reporting My guess is that
states may differ on how they’d like to do this. I don’t see a
reason we can’t make the modifications to accommodate those who would
like to do the second by adding RAPIDS codes for the congener groups to the
materials table and map them to total PCBs for reporting. My guess is that you
fall in this group. Would you like to take on the task of recommending a set of
material codes for the group to consider? Jon ______________________ From:

PCBs are attached. All these factors were created after FIRE6.23 with an
EPA date of 9/1/03. All these emission factors are for External
Combustion Boilers that burn Wood/Bark Waste. Chun Yi -----Original Message----- Chun Yi, Thanks
for the information. I believe that it is worth looking into this. We may want
to find out a few things. 1 What are the SCCs associated with these factors?,
2) Do factors exists for total PCBs for the same SCCs? 3) Do any of the states
collect data on these emissions or these processes?
