variation of environmental permits (VEP), 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 construction phase of the Project commenced on 1
November 2013 and will tentatively be completed by the end of 2018. The impact monitoring of the EM&A programme, including air quality, water quality, marine
ecological monitoring and environmental site inspections, were commenced on 1
November 2013.

Future Key Issues
Potential environmental impacts arising from the above
upcoming construction activities in the next reporting month of July 2016 are
mainly associated with dust, marine ecology 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.
Under Contract No. HY/2012/08,
Dragages – Bouygues Joint Venture (DBJV) is

Section of TM-CLKL 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

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.
High volume samplers (HVSs) were used to carry out the
1-hour and 24-hour TSP monitoring on 1, 4, 7, 10, 13, 16, 19, 22, 25 and 28 June
2016 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.

The weather condition during the monitoring period
varied from sunny to cloudy. The major
dust sources in the reporting period included construction activities under the
Contract as well as nearby traffic emissions.
A total of 10 monitoring events were undertaken in
which no Action or Limit Level exceedances of 1-hr TSP were recorded in this
reporting month. No Action or Limit
Level exceedances for 24-hr TSP were record.
Meteorological information collected at the ASR5,
including wind speed and wind direction, is provided in Appendix H.
As informed by the Contractor, Phase I Reclamation
works for the Northern Landfall was substantially completed in December 2014, a
proposal letter was sent to EPD on 21 May 2015 to seek approval for the
temporary suspension of Water Quality Monitoring. Subsequently, a letter from EPD on 5 June
2015 stated that they have no strong objection to the temporary suspension of
the water quality monitoring. Water
Quality Monitoring was suspended from 6 June 2015 effectively and will resume
when Phase II Reclamation commences in the fourth quarter of 2016 tentatively.
Impact 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, the
on-going impact line transect dolphin monitoring data collected by HyD’s Contract No. HY/2011/03 Hong
Kong-Zhuhai-Macao Bridge. Hong Kong Link Road - Section between Scenic
Hill and Hong Kong Boundary Crossing Facilities on the monthly basis is
adopted to avoid duplicates of survey effort.

monitoring.

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. 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.
The impact dolphin monitoring was carried out in the
NEL and NWL along the line transect as depicted in Figure 2.2. The co-ordinates of all transect lines are
shown in Table 2.6 below.

The Action and Limit levels of impact dolphin monitoring
are shown in Appendix D. The Event and Action plan is presented in Appendix J.
Dolphin monitoring was carried out on 1, 6, 13 and 17 of
June 2016. The dolphin monitoring
schedule for the reporting month is shown in Appendix F.
One Chinese White Dolphins sighting was recorded
during the two sets of surveys in June 2016.
It was made in NEL, while none was sighted in NWL. The single dolphin sighting was made during
off-effort search, and it was not associated with any operating fishing vessel.
None of the dolphin sightings was made in the
proximity of the TM-CLKL alignment. The
distribution of dolphin sightings during the reporting month is shown in Figure 2.3.
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 June 2016
with the results present in Tables 2.7 and 2.8.

Note:
Overall dolphin encounter rates (sightings per 100 km of survey effort) from
all four surveys are conducted in June 2016 on primary lines only as well as
both primary lines and secondary lines in Northeast and Northwest Lantau.
Due to monthly variation in dolphin occurrence within
the survey area, it would be more appropriate to draw conclusion on whether any
unacceptable impacts on dolphins have been detected in relation to the
construction activities of this Project in the quarterly EM&A reports,
where comparison on distribution, group size and encounter rates of dolphins
between the quarterly impact monitoring period and baseline monitoring period
will be made.
There was no dredging, reclamation
or marine sheet piling works in open waters during this reporting period.
Thus, Passive Acoustic Monitoring (PAM) and the day-time monitoring of Dolphin
Exclusion Zone (DEZ) by dolphin observers were not in effect during 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, five (5) site inspections were carried out on 1, 8, 15, 22 and
29 June 2016.
Key observations and recommendations during the site
inspections in this reporting period are summarized in Table 2.7.
