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.
Waste Management
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
