PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                                8 NOVEMBER 2016


          c.   results of test and test method
          d.   certification by and details of testing company or individual
          e.   discussion, conclusion and any remedial actions proposed, implemented and
               timetable for compliance.
          Stage 1 Vapour Recovery
    79.   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
    80.   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.
    81.   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.
    82.   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.
    83.   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
