About this Manual
The aggregated emissions manuals complement the NPI Industry handbooks, and are intended to enable State and Territory Governments to estimate emissions from non-industrial activities (e.g. transportation, domestic and commercial activities) and emissions from industry which are not reported because the relevant thresholds are not exceeded.
This manual deals with emissions from spray painters, smash repairers and panel beaters. It does not cover emissions from motor vehicle manufacturing.
VOCs are emitted during the application of coatings, the drying phase, and the cleaning equipment such as spray guns. Chemical reactions may also cause emissions to occur during the refinishing, drying, curing and hardening phases.
Particle emissions may occur if coatings are applied using spray guns in an uncontrolled environment. However, these emissions are considered to be comparatively very small in relation to those from other sources, and are not considered further in this manual.
Emissions of trichloroethylene used for surface cleaning are accounted for in the aggregated emissions manual for Use of Industrial Solvents (Sub-Threshold).

Application of the Manual
Each of the aggregated emissions manuals provides details of:
- the NPI substances that are expected to be emitted from the relevant aggregated source type;
- the origins or sources of the emissions, and the processes that may generate them;
- the impacts of any control equipment or procedures on those emissions;
- the broad approaches that may be employed in the estimation and spatial allocation of emissions;
- details of emission factors to be used in the estimation of emissions; and
- a series of illustrative sample calculations for each estimation technique.
