Narrabri Environmental Monitoring

Based on requirements set out in our Narrabri Plant's licence we monitor the following emissions:

Annually - Point Source Emissions and Surface Water
We are not required to monitor monthly.

The following table summarises when we expect our next set of monitoring data for each emission types.

Table 1: Expected Future Monitoring Data Sets

Emission Monitoring Expected Date to Post Next Set of Data
Point Source March 2013
Surface Water During any discharge event and 24 hours after a discharge event

 We have been working  with the EPA to improve the environmental performance of our plant.
Part of this work is shown in our licence under our Pollution Reduction Programs(PRP).  From 31 March 2012 forward any monitoring we undertake as a result of our PRP will also be published on this page.  Currently we are undertaking a Surface Water Management Plan.  Any monitoring undertaken as a result of this plan will be posted on this page.

In Conclusion

We at Cargill take all reasonable care to make sure the monitored data we obtain is correct and accurate.  If due to events out of our control we find that any of our published data is inaccurate or incorrect, we will provide a correction log.  The correction log will explain the reason for the suspected or actual incorrect data and provide an updated correct monitoring log.  The following table shows how this will be set up in the event it is needed.  To date it has not been needed.
