ORDINARY MEETING MINUTES                                                       19 JANUARY 2017


              Stage 1 Vapour Recovery
        71.   Each underground storage tank is to have:
              a.   vapour return lines that return all vapour displaced from the storage tank to
                   the delivery tanker;
              b.   vapour-tight couplings on the vapour line that close automatically when
                   disconnected;
              c.   liquid-tight couplings on the liquid transfer hoses;
              d.   incompatible liquid and vapour couplings;
              e.   spill containment enclosures for the storage tank fill connection point;
              f.   secure seals on tank filling pipes and vapour return pipes that minimise
                   vapour leaks when the pipes are not in use;
              g.   submerged fill pipes, so they terminate below the suction inlet used for
                   pumping petrol out of the storage tank;
              h.   overfill protection devices (float vent valves) fitted to shut off the petrol flow
                   at the level advised by the tank manufacturer;
              i.   overfill prevention devices (mechanical or electronic) that slow delivery of
                   petrol into the storage tank as the level in the storage tank approaches the
                   design fill level – the devices should be positioned to stop the petrol flow
                   before the float vent valve operates;
              j.   secure seals on any dip hatch openings;
              k.   a pressure vacuum valve and a 10-millimetre orifice in parallel fitted to the
                   storage tank vent pipe. Similar devices are permitted, but will only be
                   accepted by Council where they are shown by an independent certifier to
                   perform the same duty.
              Ground Water Monitoring Well
        72.   At least two (2) ground water monitoring wells must be installed on site for the
              purposes of monitoring ground water for the presence of contaminants.
        73.   The design and installation of ground water monitoring wells must be by a
              suitably qualified person experienced in designing and/or installing groundwater
              monitoring wells.
        74.   The location of the ground water monitoring wells must be installed to maximize
              the likelihood that the wells will intercept contaminated ground water whatever
              the ground water flow conditions.
        75.   The ground water monitoring wells must be:
              a.   installed and operational before use of the UPSS commences
              b.   sealed to exclude surface water, clearly marked to indicate their presence
                   and properly secured
        76.   The ground water in the monitoring wells must be tested for petroleum
              contaminants immediately after either:
              a.   the discovery whether by routine test or otherwise that ground water may
                   be contaminated by petroleum originating from the property
              b.   the discovery whether pursuant to the loss monitoring procedure for the
                   system or otherwise that the system has a leak
              c.   when requested by Council


                                                                                    Page 14 of 24
