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

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.

each individual monitoring session was presented in the corresponding monthly
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. 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 and noise source
identified at the designated monitoring stations are as follows:

3-sides barriers should be provided when conducting the cement mixing.
·
Water spraying should be applied on the unpaved area.
·
The valid NRMM label should be displayed on the PMEs.
Noise:
·
The noise barriers should be erected properly in the construction site.
Water quality:
·
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.
