RE: Updated b(a)p report draft

["Cabrera-Rivera, Orlando" <Orlando.Cabrera-Rivera@dnr.state.wi.us>]

Hi Jon,

We could discuss the draft report on Wednesday's call. One suggestion is
to include a section assessing the current B(a)P regulatory/inventory
practices of the states/province. That is, do states/province regulate
B(a)P emissions? What are the reporting thresholds?, etc. This could
give us some insight into possible recommendations for improving the
inventory.

Subject: Updated b(a)p report draft


Hi everyone,

An updated version of the b(a)p report is attached. The most significant
change is an improvement to the table of emissions by SCC. I've rolled
these emissions up by similar SCC codes and broken it into multiple
tables so that they are shown by category. This makes it much easier to
see the overall trend in the regional emissions as well as to identify
significant discrepancies or omissions. As a result, I've added some
additional questions to the individual state/province sections later on
in the report.

The major categories I think we need to address as a group are the
following:

Fireplaces and woodstoves: Table 3 shows that New York's emissions for
this category is high and Pennsylvania shows none. Several states shoe
emissions for woodstoves but not fireplaces. In all, this is likely to
be the largest source category once all the changes are made.

FCCUs: This version of the report contains a letter from 1999 suggesting
FCCU emissions, at least at one facility, are much lower that previous
estimates. WebFIRE shows two emission factors. One is controlled, the
other is not. The controlled factor is similar in magnitude to that
suggested in the letter. Can states with these sources investigate
whether their FCCUs are controlled and if the appropriate emission
factor has been used. This will have a very significant impact on the
final numbers.

Open burning: Table 6 shows that there is a lot of inconsistency as to
the reporting of b(a)p from these sources, with 3-4 states reporting
emissions from household waste burning, wildfires and prescribed burning
(but not the same 3-4 states for each category). If these were
calculated for all states, this category would have a much larger impact
on the overall numbers. This also applies to commercial cooking (see
table 16).

On-road vehicles: Minnesota has not included b(a)p from on-road

Non-road vehicles: Ohio's nonroad numbers are abnormally high for all
categories. A few states are not reporting emissions from commercial
marine vessels and/or railroads (see table 12)
