8. Environmental
monitoring works for the Project are considered effective and is generating data
to categorically identify the environmental impacts from the works and influencing factors in the vicinity of monitoring
stations.
9. For the project “Tseung
Kwan O – Lam Tin Tunnel and Associated Works” (TKO-LTT) under EP-458/2013/C,
all works contracts except Contract No. NE/2015/01 has been terminated on 17
July 2025 after the approval by EPD. As Contract No. NE/2015/01 (under TKO-LTT)
and Contract No. ED/2018/04 & ED/2020/03 (under Trunk Road T2) falls under
the same EP-458/2013/C, the reporting of the remaining EM&A works for
Contract No. NE/2015/01 (Lam Tin portion of TKO LTT) will be subsumed into the
EM&A reporting for the T2 project and presented as a single combined report
starting from August 2025.
1.1
In 2009, Civil Engineering and Development Department (CEDD)
commissioned a Kai Tak Development (KTD) – Trunk Road T2 and Infrastructure at
South Apron Investigation. The assignment covers the provision of the Trunk
Road T2 and its connections with the Central Kowloon Route (CKR) at the north
apron area and the Tseung Kwan O – Lam Tin Tunnel (TKOLTT) to the south in the
Cha Kwo Ling area.
1.2
The Trunk Road T2 Project is one of the
designated Projects under Schedule 2 of the EIAO proposed in the KTD. CEDD
submitted the Project Profile (No. PP-379/2009) on 24 March 2009 for
application for an EIA study brief for the Trunk Road T2 Project under the
EIAO. Accordingly, an EIA Study Brief (ESB-203/2009) for the Trunk Road T2
Project was issued on 30 April 2009. The Environmental Impact Assessment (EIA)
Report for the Trunk Road T2 Project was approved under the Environmental
Impact Assessment Ordinance (EIAO) on 19 September 2013. The corresponding
Environmental Permit (EP) was issued on 19 September 2013 (EP no.:
EP-451/2013).
1.3
The Contract No. ED/2018/04 is the main contract
of Trunk Road T2 (“T2 Main Works”) which comprises mainly the design and
construction of a dual two-lane trunk road of approximately 3.0km long with
about 2.7km of the trunk road in form of tunnel; ventilation and administration
buildings, environmental protection and mitigation works and etc. Moreover, the
Contract No. ED/2020/03 is the other contract under Truck Road T2 Project which
comprises mainly design and construction of the TCSS for this Project. The
EM&A programme
under the Contract ED/2018/04 and ED/2020/03 are
governed by the two EPs (EP-451/2013 and EP-458/2013/C) and two EM&A
Manuals (AEIAR-174/2013 and AEIAR-173/2013). The work areas of the T2 Main
Works are shown in Figure 1 and the

2.1
The EM&A Manual designates locations for
environmental monitoring in terms of air quality, noise, and landfill gas due
to the Project. The Project area and monitoring locations are depicted in Figures 2. Appendix A gives details of monitoring requirements.
2.2
Monitoring works/equipment were
conducted/calibrated regularly in accordance with the EM&A Manual. Copies
of calibration certificates are attached in the appendices of the corresponding
Monthly EM&A Reports.
2.3
The environmental quality performance limits,
i.e. Action and Limit Levels were derived from the baseline monitoring results.
Should the measured environmental quality parameters exceed the Action/Limit
Levels, the respective action plans would be implemented. The Action/Limit Levels for each
environmental parameter are given in Appendix
B.
2.4
Should the monitoring results of the environmental monitoring parameters
at any designated monitoring stations indicate that the Action / Limit Levels
are exceeded, the actions in accordance with the Event and Action Plans in Appendix K was carried out.
2.5
Relevant mitigation measures as recommended
in the project EIA report have been stipulated in the EM&A Manual for
implementation by the Contractor. The implementation
status of environmental mitigation measures (EMIS) is given in Appendix G.
2.6
During site inspections in the reporting
period, no non-compliances was recorded. The observations and recommendations
made during the reporting period are summarized in Appendix F.
2.7
The amount of wastes generated by the
construction activities during the reporting period is shown in Appendix H.

3.3
All 1-hour TSP monitoring was conducted as
scheduled in the reporting quarter. No Action/Limit Level exceedance was
recorded.
3.4
All 24-hour TSP
monitoring was conducted as scheduled in the reporting quarter
No Action/Limit Level exceedance was recorded in the reporting quarter.
3.5
The graphical presentations of the air quality
monitoring results are shown in Appendix
C.
3.6
All noise monitoring was conducted as
scheduled in the reporting month. No Action Level exceedance was recorded
in this reporting quarter and no Limit Level exceedance was recorded in
this reporting quarter. The graphical presentations of the noise monitoring results are shown in
Appendix D.
Groundwater Quality
3.7
The existing groundwater quality monitoring programme has been suspended
as the monitoring results had been deemed non-representative of the impact from
the project justified by two major factors: (1) influence on the monitoring
results from non-project related factors, such as anthropogenic activities and
natural phenomenon; and (2) large separation between the monitoring stations
and works area. In addition, as no alternative locations for the groundwater
quality monitoring were available, the groundwater quality monitoring has been
suspended since October 2019 upon the agreement by EPD.
Marine
Water Quality
3.8
According to Section 4.4.3 of EM&A
Manual (AEIAR-173/2013),
marine water quality impact monitoring stations is carried out during marine
construction for TKOLTT reclamation. Since the construction of Cha Kwo Ling
Tunnel from the end of Trunk Road T2 to the TKOLTT at the Eastern Ventilation
Building does not involve reclamation, the marine water quality monitoring programme stated in Section 4.4 of the EM&A Manual (AEIAR-173/2013) is therefore not applicable to
Contract No. ED/2018/04.
Groundwater Level Monitoring (Piezometer
Monitoring)
3.9
According to Section 4.1.2 of EM&A Manual (AEIAR-173/2013), daily piezometer monitoring will
be carried out on a daily basis when any tunnel construction activities are
carried out within +/- 50m of the piezometer gate in plan. As the construction
works of Cha Kwo Ling Tunnel from the end of Trunk Road T2 to the TKOLTT at the
Eastern Ventilation Building is
approximately 120m away from the piezometer gate in plan, the piezometer monitoring programme stated in Section 4.2 of the EM&A Manual (AEIAR-173/2013) is therefore not applicable to
Contract No. ED/2018/04
3.10
Post-translocation monitoring
survey is recommended in Section 6.2.5 of the EM&A Manual (AEIAR-173/2013),
to audit the success of coral translocation. Since the construction of Cha Kwo
Ling Tunnel from the end of Trunk Road T2 to the TKOLTT at the Eastern
Ventilation Building does not involve any marine works in the concerned area
mentioned in Section 6.1.2 of the EM&A Manual (AEIAR-173/2013), the
post-translocation monitoring survey stated in Section 6.2.5 of the EM&A
Manual (AEIAR-173/2013) is therefore not applicable to Contract No. ED/2018/04.
3.11
As the construction works of Cha Kwo Ling Tunnel
from the end of Trunk Road T2 to the TKOLTT at the Eastern Ventilation Building
are located more than 100m away from the Cha Kwo Ling Tin Hau temple, the
vibration impact monitoring stated in Section 8.3.1 of the EM&A Manual (AEIAR-173/2013)
is not applicable to Contract No. ED/2018/04.
3.12
The implementation of landscape and visual
mitigation measures was checked during the environmental site inspections.
Recommended follow-up actions have been discharged by the Contractor. Details
of the audit findings and implementation status are presented in Appendix F.
3.13
Since no excavation activity for this Project
was carried out within the Sai Tso Wan Landfill Consultation Zone in this
reporting quarter, therefore, no landfill gas monitoring was required.
3.14
Site audits were carried out on a weekly
basis to monitor and ensures that proper storage, transportation and disposal
practices of wastes generated from this Project include inert construction and
demolition (C&D) materials, non-inert C&D materials. Details of waste
management data is presented in Appendix
H.
3.15
According to Section 7.1.3 of EM&A Manual
(AEIAR-173/2013), no specific fisheries monitoring programme is required during
the construction phase.
3.16
During the reporting period, the major dust
