ORDINARY MEETING MINUTES                                                     19 JANUARY 2017


        54.   The canopy installed over FDA must be designed to minimise the amount of rain
              entering the dispensing area and must overhang by a horizontal distance of at
              least one-quarter of the roof height out from the vertical above the boundary of
              the demarcated fuel dispensing area as per drawing B16239-CSK01.
        55.   Stormwater from roofed areas must be directed away from the FDA catchment.
        56.   The area within the FDA must be graded and drained to a containment vessel
              (or collection sump) with no connection to stormwater or sewer or above ground
              detention tank (i.e. a ‘blind sump’). Acceptable materials of construction include
              precast concrete with a minimum certified design life of 50 years, designed in
              accordance with AS 3600-2009 Concrete structures. Other materials of
              construction may be used where approved by Council.
        57.   The containment vessel must have a capacity to hold a volume equivalent to at
              least that of the largest tanker compartment likely to be delivering fuel to the site
              plus an allowance for windblown rain (i.e. no less than 10,000litre capacity).
              Windblown rain allowance in m3 (Vr) can be calculated using the following
              equation: Vr = 0.005 x 3 x Po where Po is the total length of the open perimeter
              of the canopy in metres.
        58.   Signage indicating the rate of flow must be provided for drainage inlets in the
              FDA. Examples include 'Flows to blind sump', or 'Flows to containment facility'.
              Signage is to be painted or otherwise indicated around the drain inlets.
        59.   Where fuel deliveries are intended within the FDA, the standing area must be
              clearly demarcated and graded to the FDA containment vessel as per drawing
              B16239-CSK01.
        60.   A liquid-tight dispenser sump must be installed under each dispensing unit. It is
              to be designed to house all pipework joins and fittings and to collect and contain
              any leak from contaminating the surrounding soil/groundwater.
              Uncovered Forecourt Area (UFA)
        61.   All ground surfaces of UFA liable to contamination from vehicular activities must
              be constructed of impermeable materials, free of gaps or cracks. Suitable
              materials include asphalt, waterproofed, reinforced concrete or an approved
              equivalent.
        62.   Signage indicating the rate of flow must be provided for drainage inlets in the
              UFA. Examples may include 'flows to stormwater treatment system' or 'flows to
              creek'. Signage is to be painted or otherwise indicated around the drain inlets.
        63.   Road tanker delivery stands located within the UFA must be clearly demarcated
              and sited away from buildings, traffic areas, dispensing areas and emergency
              escape routes. The road tanker delivery stand is to be normally drained to the
              UFA stormwater quality improvement device (SQUID), however, diversion valves
              are to be engaged during fuel delivery operations to divert drainage to the FDA
              containment system (blind sump).
              Stormwater Quality Improvement Device (SQUID)
        64.   All stormwater from UFAs must be captured and drained to the approved SQUID.
        65.   The SQUID (treatment tank/ Stormwater 360 pods filter cartridges & detention
              tank) intended to be installed as part of the stormwater drainage system for the
              UFA, must incorporate the following design measures as a minimum:
              a.    steel bars or trash gates with at least 20mm spacing;
              b.    filtration devices such as sand filters or gross pollutant traps capable of
                    removing litter (diameter greater than 5mm) and at least 70% of fine
                    sediments (>125µm).
                                                                                   Page 12 of 24
