To avoid unacceptable water quality impacts during dredging	At the East of Sha Chau work site, throughout the whole duration of the construction period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3	2	The following good practice measures shall apply at all times: · All disposal vessels should be fitted with tight bottom seals in order to prevent leakage of material during transport.	To prevent leakage of material during transport	At the East of Sha Chau work site, throughout the whole duration of the disposal period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· All barges should be filled to a level, which ensures that material does not spill over during transport to the disposal site and that adequate freeboard is maintained to ensure that the decks are not washed by wave action.	To ensure that material does not spill over during transport and the decks are not washed by wave action	At the East of Sha Chau work site, throughout the whole duration of the construction and operation period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· After dredging, any excess materials should be cleaned from decks and exposed fittings before the vessel is moved from the dredging area.	To avoid potential adverse water quality impacts associated with dredging	At the East of Sha Chau dredging sites, throughout the dredging period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· The contractor(s) should ensure that the works cause no visible foam, oil, grease, litter or other objectionable matter to be present in the water within and adjacent to the dredging site.	To avoid potential adverse water quality impacts associated with dredging	At the East of Sha Chau dredging sites, throughout the dredging period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· If installed, degassing systems should be used to avoid irregular cavitation within the pump.	To avoid adverse water quality impacts due to irregular cavitation within the pump	At the East of Sha Chau work site, throughout the whole duration of the construction and operation period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· Monitoring and automation systems should be used to improve the crew’s information regarding the various dredging parameters to improve dredging accuracy and efficiency.	To improve dredging accuracy and efficiency	At the East of Sha Chau dredging site, throughout the dredging period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· Control and monitoring systems should be used to alert the crew to leaks or any other potential risks.	To alert the crew to leaks or any other potential risks	At the East of Sha Chau work site, throughout the whole duration of the construction and operation period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· When the dredged material has been unloaded at the disposal areas, any material that has accumulated on the deck or other exposed parts of the vessel should be removed and placed in the hold or a hopper. Under no circumstances should decks be washed clean in a way that permits material to be released overboard.	To prevent release of dredged materials overboard	At the East of Sha Chau dredging sites, throughout the dredging period	Contractor					Water Pollution Control Ordinance
Section 2.4 of Part 3		· All dredgers should maintain adequate clearance between vessels and the seabed at all states of the tide and reduce operations speed to ensure that excessive turbidity is not generated by turbulence from vessel movement or propeller wash.	To ensure that under-vessel turbidity is not generated by turbulence from vessel movement or propeller wash	At the East of Sha Chau dredging sites, throughout the dredging period	Contractor					Water Pollution Control Ordinance
Section 3 of Part 4	3	Water quality monitoring will be required for the following activities at the East of Sha Chau Facility: · Dredging of each pit; · Backfilling of each pit with contaminated mud; and · Capping of each pit with uncontaminated Mud.	To avoid impacts to water quality during dredging, backfilling and capping	At the East of Sha Chau work sites, throughout the dredging, backfilling and capping period	Contractor					Water Pollution Control Ordinance
Section 3 of Part 4	4	Sediment quality monitoring will be required for the backfilling activities at the East of Sha Chau Facility.	To avoid impacts to water quality during backfilling	At the East of Sha Chau work sites, throughout the backfilling period	Contractor					Water Pollution Control Ordinance
		MARINE ECOLOGY
Section 3 of Part 3	5	In accordance with the guidelines in the EIAO-TM, the general policy for mitigating impacts to marine ecological resources shall be applied in order of the following priority: · Avoidance: Potential impacts should be avoided to the maximum extent practicable by adopting suitable alternatives; · Minimisation: Unavoidable impacts should be minimised by taking appropriate and practicable measures such as constraints on the intensity of works operations (eg dredging rates) or timing of works operations; and · Compensation: The loss of important species and habitats may be provided for elsewhere as compensation. Enhancement and other conservation measures should always be considered whenever possible.	To avoid potential impacts to marine ecology	During project planning and design	Design Team					EIAO-TM
