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 Environ
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, 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.
This
is the Twenty-second Monthly EM&A report presenting the EM&A works
carried out during the period from 1 to 31 August 2015 for the Contract No. HY/2012/08 Northern Connection
Sub-sea Tunnel Section (the “Project”) in
accordance with the Updated EM&A Manual of the TM-CLK
Link Project. As
informed by the Contractor, major activities in the reporting period included:
Land-based Works
·
Surcharge Removal at Works Area – Portion N-C;
·
Box Culvert Extension at Works Area – Portion N-A;
·
Construction of capping beam and base slab for Ventilation
Shaft at Works Area – Portion N-C;

Implementation of Marine Mammal Exclusion Zone
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.
Summary
of Breaches of Action/Limit Levels
Breaches of Action and Limit Levels for Air Quality
No
Action Level or Limit Level of air quality exceedances were recorded in the air
quality monitoring of this reporting month.
Breaches of Action and Limit Levels for Dolphin
Monitoring
Whilst one (1) Limit Level
exceedance was observed for the quarterly dolphin monitoring data between June
2015 and August 2015, no unacceptable impact from the construction activities
of the TM-CLKL Northern Connection Sub-sea Tunnel Section on Chinese White Dolphins
was noticeable from general observations.
Due to monthly variation in dolphin occurrence within the study area, it
would be more appropriate to draw conclusion on whether any impacts on dolphins
have been detected related to the construction activities of the TM-CLKL
Northern Connection Sub-sea Tunnel Section 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.
Environmental
Complaints, Non-compliance & Summons
No non-compliance with
EIA recommendations,
EP conditions and other requirements associated with the construction of this
Contract was recorded in this reporting period.
No environmental complaint
was received in this reporting period.
No environmental summons was received in this
reporting period.
Reporting Change
There
was no reporting change required in the reporting period.
Upcoming

Future
Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of September 2015 are expected to be mainly
associated with dust, marine ecology and waste management.
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-354/2009A) 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.
High
volume samplers (HVSs) were used to carry out the 1-hour and 24-hour TSP
monitoring on 3, 6, 9, 12, 15, 18, 21, 24, 27 and 30 August 2015 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.

The
weather condition during the monitoring period varied from sunny to
cloudy. The major dust sources in the reporting
period include construction activities under the Contract as well as nearby
traffic emissions.
A
total of ten 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.

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.
Table 2.6 Impact Dolphin Monitoring Line Transect Co-ordinates
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 10, 14, 19 and 28 of August 2015. The dolphin monitoring schedule for the
reporting month is shown in Appendix F.
A
total of 297.72 km of survey effort was collected, with 99.6% of the total
survey effort being conducted under favourable weather conditions (ie Beaufort
Sea State 3 or below with good visibility) in August 2015. Amongst the two areas, 113.58 km and 184.14
km of survey effort were collected from NEL and NWL survey areas,
respectively. The total survey effort
conducted on primary and secondary lines were 215.91 km and 81.81 km,
respectively. The survey efforts are
summarized in Appendix I.
A total
of 6 groups of twenty-one Chinese White Dolphin
sightings were recorded during the two sets of surveys
in August 2015. All six sightings were
made in NWL during the survey in August 2015.
All six sightings were made on primary lines during on-effort search,
and the sighting was not associated with operating fishing vessel.
None of the sightings was made in the vicinity of the TM-CLKL
Northern Connection Sub-sea Tunnel Section. 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
with good visibility) in August 2015 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 August 2015 on primary lines only as well as both primary
lines and secondary lines in Northeast and Northwest Lantau.
Whilst one (1) Limit Level
exceedance (Both Northeast Lantau social cluster and Northwest Lantau social
cluster exceeded Limit Level) was observed for the quarterly dolphin monitoring
data between June 2015 and August 2015, no unacceptable impact from the
construction activities of the Northern Connection Sub-sea Tunnel Section on Chinese White Dolphins
was noticeable from general observations during the dolphin monitoring in this
reporting month.
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, four
(4) site inspections were carried out on 6, 12, 19 and 26 August 2015.
Key
observations and recommendations during the site inspections in this reporting
period are summarized in Table 2.9.
