Water sampling was unable to
carry out at WM2B and WM2B-C due to shallow water (water depth under 150mm)
Breaches
of Action/Limit levels
ES.03. In the
Reporting Period, no noise complaint which triggered Action Level and Limit Level exceedance was registered for construction
noise.
For air quality, there were 1 Action Level exceedances recorded. For water quality
monitoring, a total of 90 Action/ Limit
Level exceedance were recorded. The summary of exceedance for the
Reporting Period is shown below.

Environmental
Complaint
ES.04. In this
Reporting Period, no environmental complaints were received under the EM&A program.
Notification of Summons and Successful Prosecutions
ES.05. As notified
by the RE in the Reporting Period, a summons (ref. no. FLS7210/2017 dated 20
June 2017) was issued to the Contractor of Contract 2 (Dragages Hong Kong
Limited) for contravening the Water Pollution Control (General) Regulations. During hearing on 25 July 2017, DHK
pleaded guilty to the EPD summons – failing to report discharge within 24 hours
of its occurrence. Therefore, a
summons and prosecutions was registered for Contract 2 under the EM&A programme
in the Reporting Period.
Reporting Changes
ES.06. No reporting
changes were made in the Reporting Period.
Future key issues
ES.07. 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.
ES.08. 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.
ES.09. 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.
ES.10. 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.
