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
September and November 2016, 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.
One (1) environmental
complaint case regarding effluent discharge at the sea was referred by EPD on 28 November 2016.
Interim report will be sent to EPD after thorough investigation.
No
environmental summons was received in this reporting period.

Future
Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of December 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.

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 November 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 on 28 December 2016
tentatively. The water quality monitoring schedule in December 2016 and January
2017 is provided in Appendix
F.
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.

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 2, 7, 18 and 22 of November 2016. The dolphin monitoring schedule for the
reporting month is shown in Appendix F.
A
total of three groups of 12 Chinese White Dolphins sightings were recorded
during the two sets of surveys in November 2016. All three dolphin sightings were made in NWL,
while none was sighted in NEL. All three
dolphin sightings were made on primary lines during on-effort search, and one
of these dolphin groups was associated with an operating gill-netter.
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 November 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 November 2016 on primary lines only as well as both
primary lines and secondary lines in Northeast and Northwest Lantau.
One (1) Limit Level
exceedance was observed for the quarterly dolphin monitoring data between
September and November 2016, whilst 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 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 2, 9, 16, 23 and 30 November 2016.
Key
observations and recommendations during the site inspections in this reporting
period are summarized in Table 2.9.
