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.
ES17
Since most 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.
