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, 15, 18, 21, 24, 27 and 30
July 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

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 no exceedance of 1-hour and 24-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.
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

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 3, 9, 12 and 20
of July 2018. The dolphin monitoring
schedule for the reporting month is shown in Appendix F.
One group of 4 Chinese White Dolphins sightings were
recorded during the two sets of surveys in July 2018. The dolphin sighting was made in NWL, while
none was sighted in NEL. The dolphin
sighting was made on primary lines during on-effort search . It was not 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 July 2018 with the results present in Tables 2.7 and 2.8.

Overall dolphin encounter rates (sightings per 100 km of survey effort) from
all four surveys are conducted in July 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, four (4) site inspections were carried out on 4,
11, 18 and 25 July 2018.
Key observations and recommendations during the site
inspections in this reporting period are summarized in Table 2.9.
