ES01
This is the 106th monthly Environmental Monitoring & Audit (EM&A) report
presenting the monitoring results and inspection findings for the reporting period from 1 to 31 May 2022 (hereinafter ‘the
Reporting Period’).
Environmental
Monitoring and Audit Activities
ES02
To facilitate the project management and
implementation, Liantang/Heung Yuen Wai
Boundary Control Point and Associated Works of the Project is
divided to six CEDD contracts
including Contract 2 (CV/2012/08), Contract 3 (CV/2012/09), Contract 4 (NE/2014/02), Contract 5 (CV/2013/03), Contract
6 (CV/2013/08) and Contract 7 (NE/2014/03) and an ArshSD
contract (Contract SS C505).
ES03
Substantial
completion for the Works has been achieved for all Contracts in 2019. Proposal for partial termination of the
construction phase EM&A programme for Contracts 2, 4, 7 and SS C505 was
approved by EPD on 9 July 2020 (EPD’s ref.: ( ) in Ax (3) to EP 2/N7/A/52
Pt.17). Moreover, termination
proposal for Contract 3 was approved by EPD on 4 May 2021 (EPD’s ref.: () in Ax
(3) to EP 2/N7/A52 Pt.18). Therefore, air quality monitoring stations AM1c, AM8
& AM9b, noise monitoring stations NM1, NM7, NM8, NM9 & NM10 and water
quality monitoring stations WM4, WM4-CA & WM4-CB and ET’s site inspection
and audit for relevant works area for Contracts 2, 3, 4, 7 and SS C505 was
ceased accordingly.

WM3-C was also unable to carry out and WM1-C was also unable to carry out some
of the monitoring days 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.

Future Key Issues
ES10
Since
the construction works under the Project were substantial completed, the
potential environmental impacts associated with Project are considered
negligible.
However, the Contractor was reminded that the environmental
mitigation measures shall be properly implemented and maintained where applicable, as per the Mitigation
Implementation Schedule,
in the remaining construction period and operational phase.
