West Ridge Quarry
Site Based Management Plan




                                The left branch of Six Mile Creek is located on the eastern boundary of the Site. Six Mile Creek flows
                                to Lake McDonald (also known as Six Mile Creek Dam). Six Mile Creek is a meandering, slightly to
                                moderately disturbed, low land ephemeral creek, with a stream order 2 classification under the VMA.
                                Six Mile Creek flows for approximately 3.5 km from the Site in a northerly direction before changing
                                course to the south and discharging into Lake MacDonald.


Flooding:                       The Site is not recognised as a flood hazard area in the Cooroy Locality Planning Scheme overlay

Environmental                   The nearest sensitive receptor to the Site is a rural residence approximately 500 m from the
Sensitive                       proposed extraction area. As the Site has been an operational mine for several decades the
Receptors:                      proposed extraction area is not expected to cause any increased environmental nuisance at the
                                nearest residence. The locations of the nearest sensitive receptors are shown on Figure 2 – Site
                                and Surrounds.

Cultural Heritage:              No historical places (indigenous or non-indigenous) are known or occur on-site or within the quarry
                                development area.

Visual Amenity:                 The Site is shielded by a large area of vegetation which surrounds majority of the Site. The Site is
                                set back a considerable distance from Lake MacDonald Drive which ensures the Site is further
                                shielded from view of local traffic. The Site has been operational for several decades and the
                                proposed extraction areas will not impact upon visual amenity.

1.5          Potential Environmental Impacts and Risks
The identification of activities and their potential environmental impacts is fundamental to designing and implementing
procedures and measures proposed in the SBMP.

The risk assessment adopted is a qualitative risk-based approach designed to assess risk based on:

      the likelihood of an environmental impact or event occurring; and
      the consequences of the occurrence on the surrounding environment.

The likelihood and consequences are scored between 1 and 5 for each potential impact or event Table 3 - Definitions of
Likelihood and Table 4 - Definitions of Consequence outline the identifiers and scores used in the risk assessment.
