7. 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.
8. No reporting change in the reporting quarter.
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. The EM&A programme under this Contract is 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 works to

ENVIRONMENTAL MONITORING AND AUDIT REQUIREMENTS
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.

EM&A report.
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. One (1) 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 and noise source identified at the
designated monitoring stations are as follows:

The stagnant water should be removed regularly and avoid water ponding.
Waste / Chemical Management
·
The drip tray should be provided for the chemical container to avoid the
chemical leakage.
·
The machinery should be checked and maintenance regularly to prevent the
oil leakage.
·
The site and surrounding should be kept tidy and litter free, remove the
waste regularly.
