5       SUPPORTING DOCUMENTS

5.1     TRAFFIC IMPACT ASSESSMENT
        The traffic impact assessment prepared by Empire Engineering indicates the
        proposal would have a negligible impact on the external traffic network. The
        proposal would not be fundamentally different to the existing service station, it
        would not increase the customer catchment area, and most of the generated traffic
        would still be undiverted drop-in traffic. This has already been counted and
        accounted for in the background traffic volumes on the roundabout. As such, there
        would not be a material net increase in existing traffic volumes or impacts on the
        external traffic network and adjacent roundabout.

        The proposal has been designed to facilitate unrestricted forward gear access and
        egress from the site for all required design vehicles, including a 10.5m WCV, 10.5m
        MRV and 19m semi-trailer.


5.2     STORMWATER QUALITY MANAGEMENT PLAN
        The stormwater quality management plan prepared by Empire Engineering indicates
        the proposal would not impact existing upstream or downstream properties. The
        existing service station does not have underground drainage infrastructure or
        environmental controls—therefore the proposal would be significant improvement
        over the current situation, resulting in a benefit for the surrounding environment.


5.3     NOISE IMPACT ASSESSMENT
        The noise impact assessment prepared by Alpha Acoustics indicates forecast noise
        emissions would comply with the noise criteria requirements of the Environmental
        Protection (Noise) Policy 2008. An on-site survey was conducted for a period of
        seven days.


5.4     AIR QUALITY ASSESSMENT
        The air quality report prepared by Air Noise Environment indicates forecast
        pollutant concentrations of VOC and odour would comply with the criteria
        requirements of the Environmental Protection (Air) Policy 2008.


5.5     LIGHT SPILL REPORT
        The light spill report prepared by Cushway Blackford Consulting Engineers indicates
        the proposal passes the maximum obtrusive light test results of relevant standards
        and would not interfere with the amenity of surrounding uses.
