Future Key
Issues
Potential environmental impacts arising
from the above upcoming construction activities in the next reporting month of
February 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, 28 and 31 January 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.

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 11 1-hour TSP and 24-hour TSP monitoring were undertaken in which six
(6) Action Level of 1-hour TSP were 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 completed
on 31 December 2017. Notification of
suspension of water quality monitoring has been issued to EPD on 1 February
2018 and is in process.
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, 8, 16 and 25 of January 2018. The dolphin monitoring schedule for the
reporting month is shown in Appendix F.
A
total of 265.94 km of survey effort was collected, with
84.2% of the total survey effort being conducted under favourable
weather conditions (i.e. Beaufort Sea State 3 or below with good visibility) in
January 2018. Among the two areas,
100.20 km and 165.74 km of survey effort were collected from NEL and NWL survey
areas, respectively. The total survey
effort conducted on primary and secondary lines were 195.15 km and 70.79 km
respectively. The survey efforts are
summarized in Appendix I.
Five
groups of 20 Chinese White Dolphins sightings were recorded during the two sets
of surveys in January 2018. 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 were 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 January 2018 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 January 2018 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 3, 10, 17, 24 and 31 January 2018.
Key
observations and recommendations during the site inspections in this reporting
period are summarized in Table 2.9.
