PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                             8 NOVEMBER 2016


    60.   All ground surfaces within the FDA must be constructed of impermeable materials
          free of gaps and/or cracks. Suitable materials include waterproofed, reinforced
          concrete or an approved equivalent.
    61.   The FDA must be clearly demarcated from the outer forecourt area, access roads,
          general parking bays and all other areas to clearly delineate the higher contamination
          risk area from lower risk areas. Acceptable demarcation methods include a painted
          line on the ground, roll-over bunds, drainage lines or different coloured impermeable
          material.
    62.   The canopy installed over FDA must be designed to minimise the amount of rain
          entering the dispensing area and shall 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.
    63.   Stormwater from roofed areas must be directed away from the FDA catchment.
    64.   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.
    65.   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.
    66.   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.
    67.   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.
    68.   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)
    69.   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.
    70.   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.
    71.   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)
    72.   All stormwater from UFAs must be captured and drained to the approved SQUID.

                                                                                   Page 14 of 70
