executive summary
ES01
This is the 97th monthly Environmental Monitoring & Audit (EM&A) report
presenting the monitoring results and inspection findings for the reporting period from 1 to 31 August 2021 (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.

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.
ES05
Construction
phase for Contract 6 are substantially completed and only minor defect
rectification and minor remaining works will be carried out and scale of
remaining works were small when compare with the full swing of work during
construction period. A revised “Proposal for termination of the Construction Phase EM&A Programme for the remaining Contract 6 of the Project”
which certified by ETL and verified by IEC, was re-submitted to Environmental
Protection Department (EPD) on 15 July 2021 for approval. Site inspection with
EPD, RE, IEC and ET was conducted on 12 August 2021 and updated Proposal will
be submitted to EPD in September 2021.

Future Key Issues
ES06
In
view of substantial completion of construction work and in consideration of the
scale and nature of remaining works under Contract 6, the potential
environmental impacts associated with the remaining works for Project was considered negligible. The revised “Proposal for termination of the Construction Phase EM&A
Programme for the remaining Contract 6 of the
Project” which certified by ETL and verified by IEC, was re-submitted to EPD on
15 July 2021 for approval.
ES07
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.
