Emission estimation technique manuals

The following emission estimation technique (EET) manuals listed in alphabetical order are approved for use by industry. There are 94 EET manuals.

EET manuals are also listed by industry sector. Some industry sectors may require one or more EET manual. The NPI guide should be used in conjunction with all manuals. Diffuse emissions manuals can also be used to estimate emissions at your facility.

If reporting facilities estimate their emissions using any of the EETs provided in the Manuals, their data will be displayed on the NPI database as being of 'acceptable reliability'. Similarly, if the relevant environmental authority has approved the use of the EETs that are not outlined in the Manuals, the data will also be displayed as being of 'acceptable reliability'. It should be emphasised that the emissions data derived using any EET will have a degree of uncertainty associated with it.
