NPI Emission Estimation Technique (EET) Handbooks are regularly updated. Whenever referring to a hard copy version of a Handbook, please be sure to check that the version number and publication date matches the latest version of the document as shown on the NPI website (here). Using an outdated Handbook could cause errors in NPI calculations and require you to resubmit your NPI report.
An updated version of the Mining manual became available on the NPI website in July 2011:
The main changes in the manual since version 2.3 was issued in December 2001 are enhancement of layout and updates to selected emission factors and emission estimation techniques.
Please contact 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 any requests to create software tools to calculate emissions or other information described in NPI Handbooks.
