For approximately 2 months, trimming operations for underwater high spots will be carried out [south of Shek Kwu Chau] in the following areas: AREA 1: This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (H): (A) 22� 10.085'N / 113� 59.230'E (B) 22� 10.030'N / 113� 59.230'E (C) 22� 10.030'N / 113� 59.403'E (D) 22� 09.922'N / 113� 59.403'E (E) 22� 09.922'N / 113� 59.113'E (F) 22� 09.975'N / 113� 59.113'E (G) 22� 09.975'N / 113� 58.532'E (H) 22� 10.083'N / 113� 58.532'E AREA 2: This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (I) to (N): (I) 22� 09.353'N / 113� 58.852'E (J) 22� 09.190'N / 113� 58.852'E (K) 22� 09.190'N / 113� 59.143'E (L) 22� 08.974'N / 113� 59.143'E (M) 22� 08.973'N / 113� 58.387'E (N) 22� 09.352'N / 113� 58.387'E The works will be carried out by two grab dredgers. Some hopper barges, tugs and work boats will provide assistance. The number of vessels engaged in the works will change from time to time to suit operational requirements. A working area of approximately 100 metres will be established around the dredger and hopper barge. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the dredger and hopper barge. The works will be carried out round-the-clock. A silt curtain, extending from the sea surface to the seabed, will be established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments. Vessels engaged in the operations will display signals as prescribed in international and local regulations. Vessels navigating in the vicinity should proceed with caution.
