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.

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 were recorded in
this reporting quarter and no Limit Level exceedance were 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.
