NPI Industry reporting
Almost 4000 facilities from a wide range of industry sectors report annually to the National Pollutant Inventory (NPI). Most facilities are required to submit data to the NPI by 30 September each year.
The first step is finding out if your facility needs to report to the NPI. Industry facilities that exceed an NPI reporting threshold should report to the NPI.
Only substances for which an NPI reporting threshold is exceeded are reported to the NPI.
Use the NPI Guide to determine whether emissions from your facility should be reported to the NPI. The NPI Guide will take you step by step through the reporting process. More about the NPI Guide.
If your facility is required to report, you need to estimate emissions of NPI substances to air, land and water. Look up your industry's Emission Estimation Technique (EET) manual or refer to the more general EET manuals to find out how to estimate emissions. More about estimating emissions.
Lodge your NPI report to your state or territory environment protection agency using the new NPI Online Reporting System or a paper form. More about lodging NPI reports.
The NPI reporting period is from 1 July to 30 June each year. Nearly all facility reports are for this period.
Most reporting facilities are required to lodge their reports with the NPI by 30 September each year.
The relevant state or territory environment protection agency will then assess the reports and forward them to the Department of the Environment, Water, Heritage and the Arts for inclusion on the NPI database.
Facility data is published at the end of March each year. More about dates for reporting.
Find out what's new for the NPI - the NPI News page informs you about updated manuals and reporting information.
Attend a training session - some state and territory environment agencies provide information sessions to explain reporting requirements and methods.
There are a number of other resources available to assist facility operators in reporting their emissions to the NPI. These include:
