This section of the reporting instructions specifies the requirements for reporting emissions information that is aggregated at the configuration-level. Configuration-level emissions will include the emissions from all fuels combusted in a given configuration. Users are required to report both configuration-level and fuel-specific information for all configuration types. As with the identification information, each configuration has unique reporting requirements for emissions information.
The text below describes how to enter subpart C General Stationary Fuel Combustion Sources configuration-level emissions information. The process to edit an existing configuration type is essentially similar.
