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).

ES04
As the major construction work under Contract
3 and Contract 6 were substantially completed. In view of insignificant
environmental impacts of the remaining outstanding construction works of
Contracts 3 and 6, the revised “proposal for termination of the Construction
Phase Environmental Monitoring & Audit (EM&A) Programme for the
remaining Contract 3 and Contract 6 of the Project” which certified by ETL and
verified by IEC, was submitted to Environmental Protection Department (EPD) on 5
February 2021. Revised termination proposal for Contract 3 was submitted to EPD
on 9 April 2021 and 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.
