Future Key Issues
ES15
During wet season, 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.
ES16
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.
ES17
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.
ES18
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.
