2 David Low Way - Attachment 6 - UXO Assessment - OPEC

                                                                    OPEC - 2 David Low Highway, Castaways Beach
                                                                                       Rev 02 – AFU – 10 Aug 2017


         Provide preliminary advice regarding:
             o     the nature, location and extent of such contamination;
             o     the EO/UXO risks faced by the Client; and
             o     options to mitigate risks associated with EO/UXO.

The findings of this Assessment may change if additional information is received or reviewed.

KEY CONCLUSIONS
The key conclusions drawn from the available information are as follows:
         There is ample evidence of Army WWII and post-WWII live firing including Australian
          mortars, towed & shoulder-fired anti-tank weapons, artillery, grenades, small arms
          ammunition, blank ammunition and pyrotechnics. Munitions usage was likely ‘moderate’ to
          ‘substantial’.
         There is also evidence of limited live firing practices involving:
             o     Air Force rocket firing and air-dropped bombs; and
             o     Anti-air firing practices.
         There is currently no evidence of:
             o     large-scale munitions disposal (however isolated ‘dumping’ or disposal of small
                   quantities may have occurred); or
             o     activities involving persistent or other military chemicals.
         The precise location and extent of any remnant UXO contamination cannot presently be
          determined from historical research alone – it is possible that UXO may be found throughout
          the entire Site, in a few ‘clumps’ or, conversely, no UXO may exist within this specific area.
          Despite this uncertainty, it is currently assessed ‘likely’ that EO/UXO hazards of various types
          exist within the area.
         Many of the Client’s activities have a medium to high probability of interacting with these
          residual EO/UXO hazards and many of these interactions – if not mitigated - could
          potentially result in moderate to catastrophic consequences (loss of life, serious injury,
          incapacitation, illness, legal action or reputation damage).
         There are also activities where ‘perception of risk’ may be substantially higher than ‘actual
          risk’. Even though ‘perception of risk’ may not cause physical harm, it is still a risk that may
          have negative consequences (e.g. reluctance to work in areas, higher insurance costs and
          growing public concerns).
