Future Key Issues
ES14
As wet season is approaching, 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.
ES15
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.
ES16
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.
