001	BPRW41, Ting Kau Village	1 March 2003	Construction noise arising from bore piling activities at BPRW41 in February 2003	The Contractor erected two layers of acoustic curtains on the rockfall fence between the construction activities and Ting Kau Village to alleviate the noise impact. No exceedance was recorded at the additional noise measurement events on 6 March 2003 with 2 bore pile RCDs in operation. The Contractor was reminded to maintain sufficient mitigation measures.

002	Nullah near Ting Kau Beach	28 May 2003	EPD observed muddy wastewater being discharged into the nullah near Ting Kau Beach	Muddy wastewater was discharged to the Ting Kau Beach via a nullah nearby. The Contractor had pumped silty underground water from an excavated pit into the final collection pit located at BPRW42. The Contractor had ceased the pumping activity immediately upon notification and had later provided additional treatment tank for treating the underground water in June 2003.	Closed
003	Nullah near Lido Beach	29 May 2003	A public complaint about muddy wastewater being discharged into the nullah near Lido Beach after 18:00 from the construction sites	There was no direct evidence to associate the muddy wastewater discharge in the nullah near Lido Beach with the construction activities in nearby works areas of the Project or surface runoff from the construction sites. The Contractor’s implementation of water quality mitigation measures were assessed by the ET and most measures were properly implemented after the complaint event (Log Ref.: 002) in June 2003.	Closed
004	Low-lying works areas at E02W and E05W	4 June 2004	ER observed sediment plume from the works areas E02W and E05W	The discharge of sediment plume was likely due to high tide, which flushed silty material into the sea. The mitigation measures were deemed insufficient to avoid such problems. The Contractor rectified the problems by erection of soil bunds with sufficient height. Besides, the Contractor was reminded to regularly maintain the low-lying areas to avoid accumulation of silty materials	Closed
