I checked emissions for residential wood combustion, we did use the most conservative B(a)P emission factors from NEI for those SCCs without emission factors. The reason for not showing emissions in the repository for certain counties is no activity data for these counties. Therefore, as I mentioned in the Toronto meeting, in the B(a)P report, we need to have N/A in the table for those SCCs with emission factors but no activities.
I already added FIRE B(a)P emissions for human cremation, even though B(a)P emissions are higher than 7-PAHs.
