The NPI Guide has been updated!

If you only ever read one NPI document, make sure you read the latest version of The NPI Guide.

Version 5.2 of the NPI Guide was released today and contains the following sections:

Section 1 - An overview of what the National Pollutant Inventory is

Section 2 - Reporting thresholds and how to apply them to a particular site

Section 3 - Estimating emissions of substances which must be reported to the NPI

Section 4 - Estimating NPI substances in transfers of wastes

Section 5 - How to report emissions and transfers to the NPI

If you need to report to the NPI, please read the NPI Guide carefully to maximise the chance of fully meeting all reporting requirements.

Apart from updates to hyperlinks and NPI government contact details, there are just a few areas in which the NPI Guide has changed this year:

• additional advice has been provided that the reporting of Total Nitrogen needs to include the sum of nitrate, nitrite, organic nitrogen and ammonia, all expressed as Nitrogen; and
• clarification of advice about reporting an emission of a tripped substance as zero: emissions should only be reported as zero in circumstances where there is reasonable certainty that the NPI substance is not emitted. If the emission can not be estimated, the reported emission for a substance should be left blank and the reporting facility should explain the reason for the blank. It is recommended that this information be reported as part of the facility's public statement.

Please contact NPI+ at peter@NPIplus.com.au if you have any questions about how NPI+ can help you meet the requirements of the NPI for the 2010-2011 reporting period.

Or, you can contact the relevant government agency in your state as shown on page (iii) of The NPI Guide, or shown here on the NPI government website.
