Estimating transfers of NPI substances in waste

What are transfers?

Transfers have been defined in the NPI National Environment Protection Measure (NEPM) as the transport or movement, on-site or off-site, of substances to a mandatory reporting transfer destination or a voluntary reporting transfer destination. There are some exceptions and these include the transport or movement of substances contained in overburden, waste rock, uncontaminated soil, uncontaminated sediment, rock removed in construction or road building, or soil used for the capping of landfills.

A transfer is the transport or movement, on-site or off-site, of substances contained in waste for:

The transfers listed above are divided into mandatory and voluntary reporting destinations. If waste is transported to a destination for containment or destruction, reporting is mandatory. Containment destinations include landfill, tailings storage facilities, underground injection or other long term purpose built waste storage structure. It also includes the transport or movement of substances contained in waste to a sewerage system. Reporting may be voluntary if transfers are to a destination for reuse, recycling, reprocessing, purification, partial purification, immobilisation, remediation or energy recovery.

Do you have to report?

You should determine your requirement to report a transfer when estimating your emissions. For each substance triggered in Category 1, Category 1b or Category 3 you are also required to report any transfer of that substance. See Section 2 of the NPI Guide and the Transfer Information Booklet for further details.

Note: Transfers of Category 2 substances are not reportable - but be aware that many Category 2 substances are also Category 1 or Category 1b substances.

How do you estimate transfers?

If your facility is required to report transfers, you need to estimate these by:

Further information on reporting transfers, including some helpful examples for ten industry sectors are within the Transfers information booklet.

What has to be reported?

Information required to be reported include:

When do you have to report?

For calendar year reporters the first transfer data collection period will be from:

For financial year reporters the first transfer data collection period will be from:

The first year of transfer data will be published on the NPI website on 31 March 2010.

Further details are available in the NPI Guide, however you should also look at your industry's Emission Estimation Technique (EET) manual to assist in estimating your transfers. Please note, not all manuals have been updated to reflect the inclusion of reporting transfers. This is an ongoing task and will take time. If you do have any specific questions on transfers for your industry, please contact your local state or environment agency.
