6. 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.
1.1
In 2002, Civil
Engineering and Development Department (CEDD) commissioned an integrated
planning and engineering study under Agreement No. CE 87/2001 (CE) “Further
Development of Tseung Kwan O – Feasibility Study”
(the “TKO Study”) to formulate a comprehensive plan for further development of
TKO New Town. It recommended to further
develop TKO to house a total population of 450,000 besides the district’s
continuous commercial and industrial developments.
1.2
At present, the Tseung Kwan O Tunnel is the
main connection between Tseung Kwan O (TKO) and other
areas in the territory. To cope with the
anticipated transport need, the TKO Study recommended the provision of Tseung Kwan O – Lam Tin Tunnel (TKO-LTT) (hereinafter
referred to as “the Project”) and Cross Bay Link (CBL) to meet the long-term
traffic demand between TKO and the external areas. The site layout plan for the
Project is shown in Figure 1.
1.3
The Environmental
Impact Assessment (EIA) Report for the TKO-LTT project was approved under the
Environmental Impact Assessment Ordinance (EIAO) in July 2013. The
corresponding Environmental Permit (EP) was issued in November 2013 (EP no.:
EP-458/2013). Variations to the EP was applied and the latest EP (EP no.:
EP-458/2013/C) was issued by the Director of Environmental Protection (DEP) in
January 2017.

The major site activities undertaken in the reporting quarter are shown in Appendix M.
2.1
The EM&A Manual designates locations for environmental
monitoring in terms of air quality, noise, groundwater quality, water quality,
ecology, cultural heritage and landfill gas due to the Project. The Project
area and monitoring locations are depicted in Figures 1 - 6. Appendix A
gives details of monitoring requirements. Locations of the environmental
sensitive receivers are shown in Figures
3.1, 3.2, 4.1, 5.1, 6.2 and 9.2.
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 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 N was
carried out.

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 I.

As for marine water quality monitoring, 21 and 85 action level and limit level
exceedances in Monitoring Stations (M) were recorded.
Suspension of
Groundwater Quality Monitoring
3.13
The groundwater
monitoring was suspended since October 2019.
3.14
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 January 2020 upon the agreement by EPD.
Observation and
Exceedance Investigations
3.15
During this reporting quarter, no sand plume was observed during the
water quality monitoring and site audits, therefore there is no direct evidence
that the recent exceedances were due to reclamation activities of the Project. The
Contractor is reminded to deploy silt curtain properly when the barge
enters/exits the embayment area. If possible, the Contractor shall also move
the barge during high tide to prevent stirring up the sediments on sea bed.
3.16
Exceedances of turbidity and suspended solid
were recorded on from various monitoring stations non-specifically among all
stations including the control stations. Investigations over November 2020 – January 2021
showed that the range of SS levels recorded in reporting period remained
consistent with the records in recent months. Since we officially entered the
wet season, all Contractors are reminded to clear the drainage, repair any
broken pipes/drainage and ensure there is embankment surrounding the works area
to prevent accidental muddy water spillage or surface runoff due to heavy
downpours. Details of the exceedance investigation report can be found in Appendix K.
3.17
The graphical presentations of the marine
water quality monitoring results are shown in Appendix F. Embayment measurement at W1 was completed in December
2019.
Daily Piezometer Monitoring
3.18
Construction phase daily piezometer monitoring was carried out in the
whole period whenever tunnel construction activities were carried out within
+/- 50m of the piezometer gate in plan. The monitoring had switched to monthly
basis in 19 November 2018 as the construction activities were not within +/-
50m of the piezometer gate in plan. Since no construction had been conducted
within +/- 50m of the piezometer gate in the reporting quarter, no piezometer
monitoring was conducted in the reporting quarter.
3.19
Post-translocation coral monitoring survey shall be conducted once every
3 months for a period of 12 months after completion of coral translocation. The
post-translocation coral monitoring survey were completed in
February 2017.
3.20
Monitoring of vibration impacts at Cha Kwo Ling Tin Hau Temple commenced
on 8 April 2017. No Alert Alarm and
Action (AAA) Level exceedance was recorded in the reporting quarter.
3.21
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 H.
3.22
Monitoring of landfill gases was commenced in March 2016 and were
carried out by the Contractors at excavation
location, Portion III in the reporting quarter. No Limit Level exceedance was recorded. The graphical presentations of
the landfill gas monitoring results are shown in Appendix G.
3.23
Wastes generated from this Project include inert construction and
demolition (C&D) materials, non-inert C&D materials and marine
sediments. Details of waste management
data is presented in Appendix I.
