Opal Packaging, Matraville

The EPA continues to respond to community complaints regarding Opal Packaging at Matraville. We are monitoring activities and checking for compliance with licence conditions.


In response to reports of odours, in May 2021 we conducted an unannounced inspection of Opal during a  south west to west south west wind and a weak odour was detected offsite. We will continue to make announced and unannounced inspections of this facility and conduct odour surveys in the area.

Opal has recently installed gas monitors, designed to detect discharge of excess biogas released from pressure valves associated with the secondary water treatment plant. While the discharge of excess biogas is infrequent, in the past it has aligned with community complaints of a sulphur/rotten egg odour. The new gas monitors will trigger onsite measures designed to minimise the impact of biogas odours. Opal will also continue to undertake monthly odour surveys as per the condition on their Environment Protection Licence (EPL).

We continue to work with Opal to ensure best-practice odour control measures are implemented and emissions are monitored.


We have received many complaints of noise from the community in Matraville and surrounding areas. There are a number of potential sources of the noise including the Opal facility. We are conducting a low frequency noise monitoring campaign across the area, with monitors installed at various sites and are gathering data and investigating the potential sources. Information gathered from this campaign will help inform decisions we make regarding the Opal EPL.
