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
2, 5, 8, 11, 14, 17, 20, 23, 26 and 29 March 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).

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 two (2) Action Level exceedances
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 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 April
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 8, 12, 20 and 23 of March 2018. The dolphin monitoring schedule for the
reporting month is shown in Appendix F.
Six groups of 26
Chinese White Dolphins sightings were recorded during the two sets of surveys
in March 2018. All dolphin sightings were
made in NWL, while none was sighted in NEL. All dolphin sightings were made during
on-effort search and all 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 March 2018
with the results present in Tables 2.7 and 2.8.

conducted in March 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 7, 14, 21 and 28 March 2018.
Key observations
and recommendations during the site inspections in this reporting period are
summarized in Table 2.9.
