Future
Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of July 2020 are mainly associated with dust and
waste management issues.
According to the findings of the
Northwest New Territories (NWNT) Traffic and Infrastructure Review conducted by
the Transport Department, Tuen Mun
Road, Ting Kau Bridge, Lantau Link and North Lantau
Highway would be operating beyond capacity after 2016. This forecast has
been based on the estimated increase in cross boundary traffic, developments in
the Northwest New Territories (NWNT), and possible developments in North Lantau,
including the Airport developments, the Lantau Logistics Park (LLP) and the
Hong Kong – Zhuhai – Macao Bridge (HZMB). In order to cope with the
anticipated traffic demand, two new road sections between NWNT and North Lantau
– Tuen Mun – Chek Lap Kok Link (TM-CLKL) and Tuen Mun Western Bypass (TMWB)
are proposed.
An Environmental Impact Assessment (EIA)
of TM-CLKL (the Project) was prepared in accordance with the EIA Study Brief
(No. ESB-175/2007) and the Technical Memorandum of the Environmental Impact
Assessment Process (EIAO-TM). The EIA Report was submitted
under the Environmental Impact Assessment Ordinance (EIAO) in August 2009.
Subsequent to the approval of the EIA Report (EIAO Register Number
AEIAR-146/2009), an Environmental Permit (EP-354/2009) for TM-CLKL was granted
by the Director of Environmental Protection (DEP) on 4 November 2009, and EP
variation (VEP) (EP-354/2009/A) was issued on 8 December 2010. Subsequent
applications for variation of environmental permits (VEPs), EP-354/2009/B,
EP-354/2009/C and EP-354/2009/D, were granted on 28 January 2014, 10
December 2014 and 13 March 2015, respectively.

The EM&A programme
required environmental monitoring for air quality and environmental site
inspections for air quality, water quality and waste management. The
EM&A requirements and related findings for each component are summarized in
the following sections
In accordance with the Updated EM&A
Manual and the Enhanced TSP Monitoring Plan, impact 1-hour TSP monitoring was
conducted three (3) times every six (6) days and impact 24-hour TSP monitoring
was carried out once every six (6) days when the highest dust impact was
expected. 1-hr and 24-hr TSP monitoring frequency was increased to three
times per day every three days and daily every three days, respectively, as
excavation works for launching shaft under Contract No. HY/2012/08 Tuen Mun-Chek Lap Kok Link – Northern Connection Sub-sea Tunnel Section
commenced on 24 October 2014.
Results
of air quality monitoring were adopted from the published EM&A data of Contract
No. HY/2012/08 Tuen Mun-Chek
Lap Kok Link – Northern Connection Sub-sea Tunnel
Section ([2]).
The locations of the monitoring stations
overlapped with Contract No. HY/2012/08 are shown in Figure 2.1

One
(1) Action Level exceedance for 1-hour
TSP was recorded by the Environmental Team of Contract No. HY/2012/08
during the reporting period. No exceedance of Action
and Limit Levels for 24-hour
TSP were recorded. The exceedance was considered not related
to this Contract upon further investigation and the investigation report is
presented in Appendix G. No action is required to be undertaken in accordance with
the Event Action Plan as presented in Appendix E.
In accordance with the Updated EM&A
Manual of the TM-CLK Link
Project, landfill gas hazard monitoring should be perform to ensure that the
works area at Pillar Point Valley (PPV) Landfill is free of landfill gas during
any excavations works.
No excavation work was conducted at the
excavation area in the reporting period and thus no landfill gas hazard
monitoring was undertaken in the reporting period.
Site inspections were carried out on a
weekly basis to monitor the implementation of proper environmental pollution
control and mitigation measures under the Contract. In the reporting
month, four (4) site inspections were carried out on 5, 12, 19 and 26 June
2020.
