       It is also noted the applicant will be required to amend the current Environmental Authority
       (EA - EPPR01855314) for the current operation of the NRRC. This will provide for the operation
       of the composting facility (ERA53) to meet current environmental standards to prevent any
       environmental harm, in terms of noise, odour and water quality management from the existing
       operation and the proposed composting facility.

       6.3.3 Flood Impact Assessment

       An updated Flood Impact Assessment (FIA) dated January 2026 is provided (refer Attachment
       7).

       The FIA provides flood modelling for the site as whole and shows the proposed composting
       facility will not be affected during a 1% AEP event (refer Figure 4). It is my understanding that
       minimal earthworks are required for the construction of the proposed composting facility in
       the location shown resulting in minimal, if any change to the flood modelling for the site. In
       the circumstances, there is no need to update the flood modelling, which has recently been
       completed.

       The flood modelling has demonstrated the on-site overland flow paths are adequately
       conveyed within both the internal and external catchment flow areas. Further, there will be no
       actionable nuisance due to the change in peak water level, depth, velocity and hazard on the
       surrounding properties for all modelled AEPs 7.
