Under Contract No. HY/2012/08,
Dragages – Bouygues Joint Venture (DBJV) is
commissioned by the Highways Department (HyD) to
undertake the design and construction of the Northern Connection Sub-sea Tunnel
Section of the Tuen Mun – Chek Lap Kok Link Project (TM-CLK
Link Project) while AECOM
Asia Company Limited was appointed by HyD as the
Supervising Officer. For implementation of the environmental monitoring
and audit (EM&A) programme
under the Contract, ERM-Hong Kong, Limited (ERM) has been appointed as the
Environmental Team (ET) in accordance with Environmental Permit No.
EP-354/2009/A. Ramboll Hong Kong Ltd. was employed by HyD as
the Independent Environmental Checker (IEC) and Environmental Project Office
(ENPO). Subsequent
applications for variation of environmental permits (VEP), EP-354/2009/B,

Future Key Issue
Potential environmental impacts
arising from the above upcoming construction activities in the next reporting
month of January 2021 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, water quality and marine
ecology as well as environmental site inspections for air quality, noise, water
quality, waste management, marine ecology and landscape and visual impacts.
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
commenced on 24 October 2014.
Excavation works for lauching shaft were completed and notification of change on
air quality monitoring frequency was submitted to EPD
on 14 September 2020. 1-hr and 24-hr TSP monitoring frequency was changed to three times per day every six days and daily
every six days, respectively, since 14 September 2020.
High volume samplers (HVSs) were used to carry out the 1-hour and
24-hour TSP monitoring on 4, 10, 16, 22 and 28 December 2020 at the five
(5) air quality monitoring stations in accordance with the requirements
stipulated in the Updated EM&A Manual (Figure 2.1; Table 2.1). Wind meter was installed
at the rooftop of ASR5 for logging wind speed and wind direction. Details
of the equipment deployed are provided in Table 2.2.
Copies of the calibration certificates for the equipment are presented in Appendix E.

Operational Phase dolphin monitoring is required to be conducted by a qualified dolphin
specialist team to evaluate whether there have been any effects on the
dolphins. In order to fulfil the EM&A requirements and make good use
of available resources, Contract No. HY/2012/08 has taken over the
responsibility for implementation of dolphin monitoring from HZMB HKLR Contract
No. HY/2011/03 since October 2019.

Dolphin monitoring should cover all
transect lines in Northeast Lantau (NEL) and the Northwest Lantau (NWL) survey
areas twice per month throughout the entire construction period and operational
phase. The monitoring data should be compatible with, and should be made available for, long-term studies of small
cetacean ecology in Hong Kong. In order to provide a suitable long-term
dataset for comparison, identical methodology and line transects
employed in baseline dolphin monitoring was followed in the impact dolphin
monitoring and operational phase dolphin monitoring.
The operational phase dolphin
monitoring was carried out in the NEL and NWL along
the line transect as depicted in Figure 2.3.

Dolphin monitoring was
carried out on 1, 3, 8, and 10 December 2020. The dolphin monitoring schedule for the reporting month is shown
in Appendix F.
A single group of two Chinese White Dolphins was sighted in the two sets of surveys in December 2020. The dolphin
sighting was made in NWL, while none was sighted in
NEL. The dolphin sighting was made during
on-effort search and was made on secondary lines. The dolphin was
not associated with any operating fishing vessel.
No
dolphin sighting was made in the proximity of the
TM-CLKL alignment. The distribution of dolphin sightings during the
reporting month is shown in Figure 2.4.
The
southern end of transect line no. 8 was not travelled on 1 and 8 December
2020 during the dolphin monitoring due to the presence of construction
boats along the transect line. Part of the transect line was not
travelled due to safety concerns.
Encounter rates of Chinese White
Dolphins are deduced from the survey effort and on-effort sighting data made
under favourable conditions (Beaufort 3 or below) in December
2020 with the results present in Tables 2.9 and 2.10.

Overall dolphin encounter rates (sightings per 100 km of survey effort) from
all four surveys are conducted in December 2020 on primary lines only as well as both
primary lines and secondary lines in Northeast and Northwest Lantau.
According to the EM&A Manual,
Operational Phase Monitoring on dolphin monitoring shall be undertaken based
upon the frequency of forty-eight, one-day survey events at a
frequency of 2 per month over a period of 24 months following cessation of the
construction. The
schedule for operational phase monitoring on dolphin monitoring in Decemeber 2020 is provided
in Appendix F.
No marine
works were undertaken during the reporting period,
therefore, daily 250 m marine mammal exclusion zone monitoring was not
undertaken during the reporting period.
Site inspections were
carried out on a weekly basis to monitor the implementation of proper
