Australia's national database of pollutant emissions
Major Update on 8 May 2008
- Now uses the latest 2006-2007 data
- A lognormal (as opposed to normal) distribution is used to compare sites
- No longer divided into two posts with two files
- Read more in the post below
Placemark collection updated on 4 July 2008 with 225 corrected locations (including every post in this thread).
The National Pollutant Inventory (NPI) is a publicly accessible database containing information on the types and amounts of pollutants being emitted to the Australian environment.
Information in the database is supplied by state and territory environment agencies who receive the information from facilities in their jurisdictions. Industry information on the database is updated annually. The attached data is for the 2005-2006 reporting year.
The purpose of the inventory is to help assess the nature of pollution in Australia by drawing together information about pollutants being released into the environment. The NPI identifies the sources of emissions and whether they are emitted to air, water or land.
The NPI helps everyone to keep an eye on pollution - it's your right to know.
Further information can be found at the NPI website.

Updated on 8 May 2008 to account for new data and changed methodology.
I have updated the attached placemark collection at the top of this post with a new version that corrects some coding errors and enhances the usefulness of the data by highlighting the top polluters.
Key changes:
- A red marker is used for the top polluters and the top emissions to air, water and land are highlighted in bold.
- Where an emission of a substance to air, water or land is greater than the 95th percentile (assuming a lognormal distribution) I have noted the site as a top emitter. There are 549 air sites, 81 land sites and 51 water sites (with some overlap, a total of 600).
It is worth noting that the coordinates provided by the NPI are not always accurate. To improve this I used the Google Maps API to geocode all the premises that had an address. Where there was a street name and number, or an intersection of two streets I substituted the geocoded coordinates. 1256 of 3951 sites were geocoded in this way.

Your location for the Singleton Beef processing facility is wrong, you have placed your link over the Singleton Army base. If you turn on roads and go to the intersection of the Mitchell Line of Road and New England Highway it is just south of that location

Thanks for your comment Macwonga.
The coordinates for this site were taken from the raw data downloaded from the NPI website as the address given wasn't enough to geocode with Google Maps. It seems the position is out by around 7km. See the NPI version of the map.
If there is sufficient interest I'd be happy to provide an update with corrected coordinates, but I'm not able to check every site myself. I hope you'll agree that importing the data into Google Earth is an improvement.

Tegandrew,
so you can correct your information based on my local knowledge,
lat -32.6515°
long 151.235°
cheers,

I have adjusted the location of the beef processing facility.
More significantly, I have removed the emissions tables from this placemark file as they were not displaying properly in the Community Layer. I have been told that this is because there is a limit of around 1000 characters in those placemarks. Returned on 8 May 2008 as it seems Google has improved their ability to handle large placemarks.
As the listing of emission data for each site was a key factor in uploading the data I have posted the full data to the Open Forum so that you can still download it, but so it won't appear in the Community Layer. No longer necessary but will be retained for a while.
Here's hoping this works.

I have enhanced the placemark file to show a visual representation of the emissions from each site by extending a coloured polygon above the site.
The width of the polygon is proportional to the number of substances emitted (reported) by each site. This is the "footprint". The height of the polygon is proportional to the size of the emissions. Red is for air emissions, blue for water and yellow for land.
Since it would be meaningless to add up the kg emitted of each substance (the big emissions would drown out the smaller ones) I have linearised the data assuming a lognormal distribution. I did this by calculating the Z-score of each substance emitted relative to national emissions. I then added the Z-scores for all the emissions of each site and divided by the square root of the number of emissions.

Your co ordinates for McCains in ballarat are significantly out. It is where you have marked Masterfoods which i think (i am not certain) are the same company but that is definately the site of McCains.
