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 ¡V Zhuhai ¡V Macao Bridge (HZMB). In order to cope with the anticipated
traffic demand, two new road sections between NWNT and North Lantau ¡V Tuen Mun
¡V 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-354/2009A) was issued on 8 December 2010. Subsequent applications for variation of
environmental permits (VEPs), EP-354/2009/B,

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, 30 April 2015 at the five (5) air quality

The Action and Limit levels of water quality impact
monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix K.
The schedule
for water quality monitoring in April 2015 is provided in Appendix F.
During this
reporting period, no marine works was carried out in this Contract. It is useful to note that heavy marine
traffic (not associated with the Project) was commonly observed nearby the
Project site and its vicinity.
Impact water
quality monitoring was conducted at all designated monitoring stations in the
reporting month. Results and
graphical presentations of impact water quality monitoring are presented in Appendix I.
In this reporting
period, a total of thirteen monitoring events were undertaken in which no Action
Level or Limit Levels of exceedances for impact water quality monitoring was recorded.
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 2.3. The co-ordinates of all transect lines
are shown in Table 2.8 below.

The Action and
Limit levels of impact dolphin monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix K.
Dolphin
monitoring was carried out on 8, 10, 17 and 22 of April 2015. The dolphin monitoring schedule for the
reporting month is shown in Appendix F.
A total of 300.70
km of survey effort was collected, with 95.5% of the total survey effort being
conducted under favourable weather conditions (ie Beaufort Sea State 3 or below
with good visibility) in April 2015. Amongst the two areas, 114.40 km and 186.30
km of survey effort were collected from NEL and NWL survey areas, respectively.
The total survey effort conducted
on primary and secondary lines were 217.91 km and 82.79 km, respectively. The survey efforts are summarized in Appendix J.
A total of 3 groups of thirteen Chinese
White Dolphin sightings were recorded during the two sets of surveys
in April 2015. All sightings were
made in NWL during the survey in April 2015, while no dolphin was sighted in NEL. One of the three sightings was made on
primary lines during on-effort search, and the sighting was not associated with
operating fishing vessel.
None of the sightings was made in the vicinity of
the TM-CLKL Northern Connection Sub-sea Tunnel Section. The distribution of
dolphin sightings during the reporting month is shown in Figure 2.4.
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
with good visibility) in April 2015 with the results present in Tables 2.9 and 2.10.

Note: Overall dolphin encounter rates (sightings per
100 km of survey effort) from all four surveys are conducted in April 2015 on
primary lines only as well as both primary lines and secondary lines in
Northeast and Northwest Lantau.
The average
group size of Chinese White Dolphins in April 2015 was 4.33 individuals per
group. Two of the three dolphin
groups were composed of 2-3 animals, while another larger group of 8 dolphins were also
sighted during the monitoring period.
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 1, 9, 15, 22 and 29 April 2015.
Key
observations and recommendations during the site inspections in this reporting
period are summarized in Table 2.11.
