Appeal judgement 30-32 Doonella St Tewantin - MCU21-0013 OPW21-0013

      b.    where otherwise, upon completion of the works associated with the development.
      Any repair work which proposes to alter the alignment or level of existing services and
      assets must first be referred to the relevant service authority for approval.
      Erosion & Sediment Control - Works adjacent to High Ecological Significance
      Water
91.   Prior to the requesting the pre-start meeting the applicant must engage a Certified
      Professional and Erosion Control to prepare and provide to Council scheduling plans for
      the development which demonstrate that construction can be undertaken in a manner
      consistent with Accepted best practice standards and all relevant conditions of this
      approval. * (Refer to Advisory Note).
92.   The applicant must engage a CPESC, or other suitably trained professional, (i.e. who
      has completed the CPESC training, and has a minimum of 5 years site experience
      supervising Erosion and Sediment Control management) to undertake weekly site visits
      to inspect and certify whether or not required Erosion and Sediment controls are properly
      installed and maintained to achieve the requirements on this approval.
93.   Construction must be managed such that less than 2,500m2 of soil is exposed at any
      time.
94.   Exposed soil is only permitted between the months of May to October, and all
      catchments with these soils must drain to sediment treatment features to achieve
      50mg/L TSS prior to release of waters from the site. Outside these months the site must
      achieve a C factor of 0.05 at all times.
95.   A construction hold point with a council delegate and supervising RPEQ must be
      established prior to commencement of cut to fill earthworks for each stage of the
      development. The hold point must be held as soon as reasonably practical and prior to
      the first rain event forecast following initial tree clearing or removal of soil stabilising
      material for each stage. At the hold point inspection, all required sediment basins, drains
      and bunds to divert waters away from disturbed soil or soils about to become exposed
      through cut to fill activities must be installed. All areas that will not require earthworks in
      the imminent cut to fill operation must be stabilised to prevent entrainment of sediments
      into receiving waters.
96.   Cut to fill earthworks must not commence until after the Supervising CPESC has certified
      that all installed erosion and sediment controls required by this approval are sized in
      accordance with conditions of the approval and the written acceptance of the certification
      is provided to the supervising RPEQ by Council officers.
97.   Prescribed Water Contaminants (as defined in Schedule 10 of Environmental Protection
      Regulation 2019) must not be released from the site or to waters within the site, or be
      likely to be released should rainfall occur, unless all reasonable and practicable
      measures are taken to prevent or minimise the release and concentration of
      contamination.
98.   Sediment and erosion control measures must be in place prior to works commencing. If
      such measures are not in place or are not satisfactory, “on the spot” fines may be issued.
      Such fines can be issued if sediments from the site are found to enter or have the
      potential to enter Council’s stormwater system, natural waterways, any downstream
      stormwater filtration system or adversely impacting on other properties. The sediment
      and erosion control design and measures have NOT been approved, it is the site's
      Supervising Engineer who is responsible for ensuring that the sediment and erosion
      control measures have:
      a.    Been duly designed by an RPEQ or CPESC and constructed in accordance with
            "best practise" methods;
