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 provides guidance on estimating aggregate emissions from Service Stations. Facilities engaged solely in the retail sale of petrol and diesel are not required to report their emissions under the NEPM for the NPI. However, states and territories (jurisdictions) will be required to estimate and report on aggregated emissions from these sources under agreed arrangements.
Service stations supply petrol, diesel and related products to road vehicles. Emissions are generated from the unloading of fuel from tankers to underground storage tanks, underground storage tank breathing losses, and vehicle refuelling.
Petrol and diesel contain a mixture of volatile organic compounds (VOCs). VOCs is a general term which refers to a large and diverse group of chemicals including hydrocarbons, oxygenates and halocarbons. A number of these substances are listed in Table 2 to Annex of the NEPM.

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.
