SUPERSEDED - Decision Notice OPW26 0033 (As Published)

                      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;
                      b.      Been revised by an RPEQ or CPESC to address the issues raised by changes in the
                              projected construction schedule and/or methods;
                      c.      Been revised to address predicted rainfall events; and
                      d.      Achieve the desired environmental outcomes.
                      Council may request further controls to be installed should the implemented measures be
                      found inefficient.
               67.    The erosion and sediment control measures must be designed, installed and maintained in
                      accordance with the supervising engineer’s instructions and the current best practice
                      standards. A copy of the latest erosion and sediment control plan, prepared and endorsed
                      by a suitably qualified person (RPEQ/CPESC), must be made available to Council within 5
                      business of request.
                      (*) Refer to Advisory Note
               68.    All erosion and sediment controls must be inspected to ensure the controls are not being
                      bypassed. Inspections must occur and be electronically recorded:
                      a.      at least daily (when work is occurring on site) or weekly (when work is not occurring on
                              site); or
                      b.      within 24 hours of expected rain; or
                      c.      within 18 hours of a rainfall event (i.e. an event of sufficient intensity and duration to
                              mobilise sediment on site).
               69.    Earthworks and the implementation of erosion and sediment controls are undertaken in ways
                      which ensure flooding characteristics (including stormwater quantity characteristics) external
                      to the development site are not worsened during construction for all events up to and
                      including the 1% AEP (1 in 100 year ARI) event.
               70.    The developer must ensure non-essential exposure of soil is prevented by restricting the
                      extent of disturbance and minimising the duration of soil exposure to adverse weather
                      conditions and effectively turf, cover or stabilise any disturbed area without delay and prior
                      to rainfall occurring.
               71.    The developer must ensure sediment does not leave the site or enter onto adjoining
                      properties or Council’s drainage system due to surface runoff or on tyres of vehicles and/or
                      machinery. It is essential to implement appropriate approved erosion and sediment control
                      measures throughout the site during all phases of construction including vehicle shakedown
                      pad/grid (or similar) at the access to the construction site. Where sediments or other
                      contaminants are deposited on a road, they must be removed so as not to enter Council’s
                      drainage system or waterways.
                      Damage to Services and Assets
               72.    Any damage caused to existing services and assets as a result of the development works
                      must be repaired at no cost to the asset owner at the following times:
                      a.      where the damage would cause a hazard to pedestrian or vehicle safety, immediately;
                              or
                      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.
