Notes:

* Sources included in this initial sector analysis by the workgroup were limited to those that are greater than 2% of either the 1998 draft U.S. or 1999 Ontario emissions inventories. These inventories represented the best information available at the time of workgroup discussions; values presented in these inventories are currently under review and will potentially change in the final versions.
