Executive Summary
ES.01.
This is the 28th Quarterly
EM&A Summary Report for the “Liantang/Heung Yuen Wai Boundary Control Point
and Associated Works” under Environmental Permit No. EP-404/2011/D (hereinafter ‘‘the EP’’), covering the period from 1 May 2020 to 31 July 2020
(hereinafter “Reporting Period”).
Environmental Monitoring and
Audit Activities
ES.02. Proposal for partial termination of the
construction phase EM&A programme for Contract 2,
Contract 4, Contract 7 and Contract SS C505 was approved by Environmental
Protection Department (EPD) on 9 July 2020 (EPD’s ref.: ( ) in Ax (3) to EP
2/N7/A/52 Pt.17). The termination
proposal covers air quality monitoring stations AM1c and AM8, noise monitoring
stations NM1 and NM7 and ET’s site inspection and audit for relevant works area

(*) During
the whole reporting period, water sampling was unable to carry out at WM2B, WM2B-C due to shallow water.
Besides, WM3-C was also unable to carry out in most of the monitoring days due
to shallow water. (Water depth under 150mm)

Number of air monitoring location changed to 7 since the partial termination
proposal approved by EPD on 9 July 2020.

Environmental
Complaint
ES.05.
No environmental
complaint was recorded in the Reporting Period.
Notification of Summons and Successful Prosecutions
ES.06. No environmental summons or successful
prosecutions were recorded in the Reporting Period.
Reporting Changes
ES.07. Proposal for
partial termination of the construction phase EM&A programme
for Contract 2, Contract 4, Contract 7 and Contract SS C505 was approved by EPD
on 9 July 2020 (EPD’s ref.: ( ) in Ax (3) to EP 2/N7/A/52 Pt.17). Therefore, air quality monitoring
stations AM1c and AM8, noise monitoring stations NM1 and NM7 and ET’s site
inspection and audit for relevant works area for Contract 2, 4, 7 and SS C505
was ceased accordingly.
Future key issues
ES.08. 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.
ES.09. 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.10. 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.
