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) ______________________ Jon Dettling Great Lakes Commission 734-971-9135 dettling@glc.org
