S 3.3.3	Standard practice in Hong Kong also includes using a bubble curtain/jacket to aid in attenuating underwater sound propagation. Such practice uses air bubbles to reduce noise by reflecting, scattering and absorbing the sound (in the form of underwater pressure pulses) produced by the piling works. Details will be agreed in advance of construction works with EPD.	During Percussive Piling works for Jetty	Contractor(s) and ET		ü			-
S 9.10	To reduce underwater sound levels associated with percussive piling, the following steps will be taken: - Quieter hydraulic hammers should be used instead of the noisier diesel hammers; - Instigate ‘ramping-up’ of the piling hammer to provide an advance warning system to marine mammals in the vicinity - Acoustic decoupling of noisy equipment on work barges should be undertaken.	During Percussive Piling works for Jetty	Contractor(s)		ü			-
S 9.10	An exclusion zone of 500 m radius will be scanned around the work area for at least 30 minutes prior to the start of percussive piling.

S 9.10	No dredging works for the submarine gas pipeline installation works along the west Lantau pipeline route as well as the pipeline route along the border of the Sha Chau Lung Kwu Chau Marine Park will take place during the peak calving season of the Indo-Pacific Humpback Dolphin, ie March through August.

S 9.10	A marine mammal exclusion zone within a radius of 250 m from the pipeline dredging vessel will be implemented during the construction phase. An exclusion zone of 250 m radius will be scanned around the dredger for at least 30 minutes prior to the start of dredging. If cetaceans are observed in the exclusion zone for a continuous period of 30 minutes, dredging will be delayed until they have left the area. As per previous practice in Hong Kong, should cetaceans move into the dredging area during dredging, it is considered that cetaceans will have acclimatised themselves to the works therefore cessation of dredging is not required. Except the pipeline section along Urmston Road (waters of busy marine traffic), dredging works will be restricted to a daily maximum of 12 hours with daylight operations. Because of marine traffic constraints, grab dredgers may need to operate 24 hours on the pipeline section which crosses the Urmston Road channel off Black Point enabling completion in the shortest possible time.
