Deer Park land remediation
04 Sep 2015
Orica is remediating and integrating sections of its Deer Park property into the City of Brimbank’s and western Melbourne’s economy and community. Orica has been working closely with government (Local and State) in this regard, and in 2014 almost half the site – some 70 hectares – was rezoned from industrial to commercial by the local government.
From the mid 1870s until the late 1980s, the site manufactured nitroglycerine (NG) – a component of TNT. NG was manufactured and stored on approximately 12 hectares of the existing site. This land must be remediated to ensure safe future use. Over the last few years Orica has undertaken soil and groundwater sampling of the site, and has not found any issues of NG levels beyond what is safe.
We have no reason to believe that there is any issue with NG on site. The NG former area was decontaminated and production buildings and equipment were demolished. However, given the fact that NG in sizeable pockets can retain its energy and therefore its potential to detonate, we are taking all safety measures necessary.
From 7 September, the soil will be turned and sampled by using a remotely operated bulldozer with a specifically designed blast protection shell. The shell includes layers of steel and rubber which is designed to suppress a potential detonation. It is a one-off design that has undergone extensive testing, including live testing at a remote detonation facility. We expect this initial work to take some months.
