Investigation
Reports for water quality exceedances have been conducted by ET accordingly. In our investigation, the Contractor had implemented
water quality mitigation measures and no adverse water quality impact was
observed during site inspection. It was concluded that all exceedances recorded at WM3x were unlikely
caused by the works under the Project.

Future Key Issues
ES15
In forthcoming dry season and in consideration of construction sites under the Project are
located adjacent to villages, the Contractors should fully implement air
quality mitigation measures to reduce construction dust emission.
ES16
Nevertheless, preventive measures for muddy water or other water
pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma Wat Channel, Ping
Yuen River, Kwan Tei River or public area should be properly maintained. The Contractors should paid special
attention on water quality mitigation measures and fully implement according
ISEMM of the EM&A Manual.
ES17
In addition, all
effluent discharge shall be ensure to fulfill Technical Memorandum of Effluent
Discharged into Drainage and Sewerage Systems, inland and Coastal Waters
criteria or discharge permits stipulation.
ES18
Construction noise would be a key environmental
issue during construction work of the Project. Noise mitigation measures such as using
quiet plants should be implemented in accordance with the EM&A requirement.
