2) The exceeded results were similar or within the ranges baseline monitoring results;

3) Sediment plume due to natural fluctuation of shallow water was observed;

4) Adverse water quality outside the site boundary was observed while no pollution source from this Contract was observed and no construction vessel for this Contract was travelling nearby. Dispersion of sediment plume to the monitoring stations from the area outside the site boundary (i.e. works area not under and related to HY/2011/09) was also observed.

Dolphin Monitoring

9. There was an Action Level exceedance of dolphin monitoring for the quarterly monitoring data (between September to November 2017). The exceedance will be reported and evaluation of impacts on dolphins due to construction work will be conducted in the quarterly EM&A report.
