Remark:
(*) Water
sampling was unable to carry
out at WM2B and WM2B-C in the Reporting Period due to shallow water. Besides, WM3-C
was also unable to carry out in the Reporting Period due to shallow water. (Water depth under
150mm). WM4, WM4-CA and WM4-CB were ceased after last monitoring carried
out on 3 May 2021 according to Partial Termination Proposal for Contract 3
approved by EPD on 4 May 2021.
(#)
Number of air monitoring location changed to 6 since the partial termination proposal
approved by EPD on 9 Jul 2020 and 4 May 2021.
(~)
Number of noise monitoring location changed to 5 since the partial termination proposal
approved by EPD on 9 Jul 2020 and 4 May 2021.
ES04
Revised termination proposal for Contract 3
was submitted to EPD on 9 April 2021 for approval. The termination proposal
covers air quality monitoring station AM9b, noise monitoring stations NM8, NM9
and NM10, Water Quality monitoring stations WM4, WM4-CA and WM4-CB and ET’s
site inspection and audit for relevant works area for Contract 3. The proposal
was approved by EPD on 4 May 2021 (EPD’s ref.: () in Ax (3) to EP 2/N7/A52
Pt.18). The revised termination proposal for Contract 6 was still under revised
by ETL.

Future Key Issues
ES11
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.
ES12
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.
ES13
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.
