I think it is better
to have new codes in RAPIDS since the toxicity profile for these congeners may
be widely different.
The suggested RAPIDS
codes with the same convention as PCDDs and PCDFs are:
|
CAS# |
Pollutant |
Suggested
RAPIDS codes |
|
7012-37-5 |
2,4,4'-Trichlorobiphenyl |
TRICB,244 |
|
2051-60-7 |
2-Monochlorobiphenyl |
MONOCB,2 |
|
2051-24-3 |
Decachlorobiphenyl |
DECACB |
|
2050-68-2 |
Dichlorobiphenyl |
DICB,TOT |
|
28655-71-2 |
Heptachlorobiphenyls,

26601-64-9 |

To include emissions
of these compounds in the repository database for MN we need to have following
steps:
- Create new RAPIDS
codes
- Enter state or
generic emission factors for them
- Calculate
emissions
- Export data from
RAPIDS
- Import data to the
repository
My question is should
we do all these for the 2002 EI or we start to include them in the 2005
EI?

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?
