Air quality monitoring

Latest air quality monitoring results and graphs

Air quality monitoring is conducted at the future terminal site. The latest graphs show the levels of nitrogen dioxide (N02), and particulate matter PM10 and PM2.5 (referring to particles less than 10 and 25 micrometres in diameter respectively). The results are referenced against guidelines levels from the NSW Office of Environment and Heritage (OEH) and the National Environment Protection Measure for Ambient Air Quality ('Air NEPM'), which is the guideline for PM2.5.

The measured PM and NO2 levels are generally well within the guidelines.

Onsite monitoring of PM2.5 began in April 2014. Prior to this PM2.5 data was provided by the OEH for the South West Sydney region.

Particulate matter can be present in the air as a result of natural events such as bushfires or dust storms, or human activities such as burning fossil fuels and construction. Exceedances of the OEH air quality criterion are rare and only tend to occur due to bushfires or hazard reduction burning in the Sydney basin.

Please note: onsite monthly air quality data from the Moorebank intermodal terminal site is not available for May to July 2015, and has been substituted with data from the NSW Government of Environment and Heritage (OEH) air quality monitoring station at Rose Street, Liverpool. This is due to a fault with MIC's onsite air quality monitoring equipment, which has now been replaced. For more information about this fault and the appropriate use of the (OEH) substitute data, please refer to the letter provided by MIC's environmental monitoring specialists.
