Future Key Issues
ES14
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,
in particular for working areas near Ma Wat Channel and Ping Yuen River.
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.
