Presented by: Science Applications International Corporation and Environ International Corporation

2. Methodology Discussion: Combustion Sources
Methodologies outlined in Task 2 report include measurement and emissions factor-based methods
Methodologies used in the development of the screening-level inventories were described in further detail
Reporting regulations developed by WCI member states/provinces may select alternative methodologies to those used in the screening-level inventories
Goal of this discussion is to gather comments on differences between methodologies from all TWG participants
Comments would be included in the Task 2 report
Comments assist state/province reporting regulation development process
