5    RECOMMENDATIONS

The following recommendations are set to reduce the potential for the wave pool discharge waters
to impact groundwater dependant ecosystems:

    •    Discharge water is dispersed over a broad area and not concentrated to beneath tanks;
    •    Discharge water is released as far from the NP wetland as practicable but no less than 50-
         100m;
    •    Discharge water resembles natural rainfall water chemistry prior to being dispersed;
    •    An Environmental Management Plan is prepared, approved and enacted to monitor the
         impacts of the wave pool discharge to the local groundwater and adjoining groundwater
         dependant ecosystems. The EMP should include, but not be limited to, a Groundwater
         Monitoring Program (GMP) and a Vegetation Monitoring Plan (VMP). The requirement to
         have the EMP approved can be set as a condition of approval of the MCU application;
    •    A Groundwater Monitoring Program (GMP) is prepared, approved and enacted to monitor
         the potential for impact to the local groundwater organisms, levels and chemistry. This
         would entail installation of piezometer both upslope and downslope of the proposed
         overflow discharge area to enable assessment of pre and post discharge groundwater
         conditions. 2 piezometers may be required downslope where a broad application area is
         employed, as recommended. An appropriate volume of baseline data should be collected
         to ensure natural variations in groundwater characteristics are not misinterpreted as direct
         impacts of the discharge.
    •    A Vegetation Monitoring Plan (VMP) is prepared, approved and enacted to monitor the
         floristic and structural characteristics of the groundwater dependant flora abutting the wave
         pool location in the NP. It is envisaged the inspections associated with the VMP would be
         carried out at the same time the groundwater monitoring events occur.
