Key Issue
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of May 2018 are mainly associated with dust, marine
water quality, 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 April 2018 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

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 1-hour TSP and 24-hour TSP monitoring were undertaken in which one
(1) Action Level exceedance of 1-hour TSP was recorded in this reporting month.
Meteorological
information collected at the ASR5, including wind speed and wind direction, is
provided in Appendix H.
Seawall
Enhancement Works at Northern Landfall has been completed on 31 December
2017. Notification of suspension of
water quality monitoring has been approved by EPD on 2 March 2018. Water Quality Monitoring will resume after
the commencement of Seawall Modification Works at Southern Landfall in May 2018
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.

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, 17, 19 and 25 of April 2018. The dolphin monitoring schedule for the
reporting month is shown in Appendix F.
Three
groups of 4 Chinese White Dolphins sightings were recorded during the two sets
of surveys in April 2018. All dolphin
sightings were made in NWL, while none was sighted in NEL. All dolphin sightings were made during
on-effort search and two of the three were made on primary lines. None of the dolphin groups were 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 2.3.
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 April 2018 with the results present in Tables
2.7 and 2.8.

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 April 2018.
Key
observations and recommendations during the site inspections in this reporting
period are summarized in Table 2.9.
