Summary of
Breaches of Action/Limit Levels
Breaches
of Action and Limit Levels for Air Quality
Two (2) Action Level exceedances of
1-hour TSP and one (1) Action Level exceedance of 24-hour TSP were recorded on
21 October 2017. Two (2) Action Level exceedances
of 1-hour TSP were recorded on 27 October 2017.
Investigation reports will be provided in the
next monthly EM&A report. Investigation reports of air quality
exceedances on 12, 18 and 27 September 2017 are provided in Appendix K.
Breaches
of Action and Limit Levels for Dolphin Monitoring
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.

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 3, 6, 9, 12, 18, 21, 24, 27 and 30 October
2017 at the five (5) air quality monitoring stations in accordance with the requirements
stipulated in the Updated EM&A Manual (Figure

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 9 1-hour TSP and 24-hour
TSP monitoring were undertaken in which four (4) Action Level exceedances of
1-hr TSP and one (1) Action Level exceedance of 24-hr TSP were recorded in this
reporting month.
Meteorological information collected at the ASR5,
including wind speed and wind direction, is provided in Appendix H.
Marine works for Phase II reclamation of Northern
Landfall were substantially completed in the end of May. Thus, no impact marine water quality
monitoring was conducted during the reporting period. Impact marine water quality monitoring for
Northern Landfall will resume during the seawall enhancement works at Northern
Landfall in November 2017 in accordance with the requirement in the Contract
Specific EM&A Manual.
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 4, 9, 18 and 26 of
October 2017. The dolphin monitoring
schedule for the reporting month is shown in Appendix F.
Four groups of 8 Chinese White Dolphins sightings were
recorded during the two sets of surveys in October 2017. All dolphin sightings were made in NWL, while
none was sighted in NEL. All dolphin
sightings were made during on-effort search and were made on primary lines. One of the dolphin groups was associated with
an operating purse-seiner.
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 2.3.
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 October 2017
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 October 2017 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, four (4) site inspections were carried out on 4, 11, 18 and 25
October 2017.
Key observations and recommendations during the site
inspections in this reporting period are summarized in Table 2.9.
