Environmental Management Controls




6          Environmental Management Controls
           The following specific environmental management controls relevant to MSES values which the
           appointed dredge contractor will be contractually required to comply with:

           • Preparing a detailed Environmental Management Plan for works.

           • Minimising construction lighting, noise and other direct disturbance (e.g. presence of construction
             plant and personnel), based on best practice standards, particularly during installation/removal of
               the temporary delivery pipeline.

           • Stop works procedures will be applied if there is a wildlife incident e.g. specific interaction between
               contractors and animals until a suitable corrective measure can be applied, such as additional
               training for construction staff in procedures.

           • Undertaking water quality monitoring during dredging and beach nourishment and implementing
             stop works procedures if targets exceeded.

           • Setting water quality limits and requiring either stop works or corrective actions in the event of an
             exceedance.

           • Limiting dredging to above -3m AHD, where the risk of encountering acid sulfate soil material is
               low. Regular testing of material to be dredged will also be undertaken to ensure that no acidic
               material is disturbed.

           • Contamination testing of material to be dredged prior to the commencement of works to ensure
             material is suitable for placement.

           • Dredging will be undertaken during winter months, when there are reduced numbers of shorebirds
               present.

           • Areas to be dredged and nourished will be checked for breeding birds prior to the commencement
             of works by a qualified spotter/catcher. Should breeding birds be present, works will be moved
               elsewhere until they move on, or the nest moved.

           • On-board staff will undertake regular visual checks for marine fauna e.g. turtles; should they be
             observed, dredging will slow or cease until the fauna has moved on.

           • Any areas of marine plants and dunal vegetation will be clearly marked prior to nourishment, so
             that placement over marine plants will be avoided.

           • Dredge protocol to reduce the likelihood of entrainment including dredge vessels not turning
             suction head on until device lowered to the sea floor.

           • Dunal vegetation containing marine plants will be clearly marked, so that nourishment can be
             placed around these areas and not directly on dunes or marine plants.
