RE: PCBs



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?

The emission factors for 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,

 

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?

FIRE contains emission factors for the following pollutants, PCB congeners.  However, RAPIDS does not have material cods for them.  Do we want to create new material codes?

 

CAS#                        Pollutant

7012-37-5                   2,4,4-Trichlorobiphenyl

2051-24-3                   Decachlorobiphenyl

2050-68-2                   Dichlorobiphenyl

28655-71-2                 Heptachlorobiphenyls, Total

26601-64-9                 Hexachlorobiphenyls, Total

25429-29-2                 Pentachlorobiphenyls, Total

26914-33-0                 Tetrachlorobiphenyls, Total
