Implementation
of Marine Mammal Exclusion Zone
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.
Summary of Breaches of Action/Limit Levels
Breaches of
Action and Limit Levels for Air Quality
No exceedance of 1-hour and 24-hour TSP was recorded
in this reporting month.
Breaches
of Action and Limit Levels for Dolphin Monitoring
One (1)
Limit Level exceedance was observed for the quarterly dolphin monitoring data
between March and May 2018, whilst no unacceptable impact from the
construction activities of the TM-CLKL Southern Connection Viaduct Section on
Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) was noticeable
from general observations. Due to
monthly variation in dolphin occurrence within the Study Area, it would be more
appropriate to draw conclusion on whether any impacts on dolphins have been
detected related to the construction activities of the TM-CLKL Southern
Connection Viaduct Section in the quarterly EM&A reports, in which
comparison on distribution, group size and encounter rates of dolphins between
the quarterly impact monitoring period and baseline monitoring period will be
made.

Future Key Issue
Potential environmental impacts arising from the above
upcoming construction activities in the next reporting month of June 2018 are
mainly associated with dust, 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
May 2018 at the five (5) air quality monitoring stations in accordance with the

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 7, 10, 16 and 30
of May 2018. The dolphin monitoring
schedule for the reporting month is shown in Appendix F.
A total of 261.40 km
of survey effort was collected, with 83.9% of the total survey effort being
conducted under favourable weather conditions (i.e.
Beaufort Sea State 3 or below with good visibility) in May 2018. Among the two areas, 95.70 km and 165.70 km
of survey effort were collected from NEL and NWL survey areas, respectively. The total survey effort conducted on primary
and secondary lines were 189.44 km and 71.96 km respectively. The survey efforts are summarized in Appendix I.
No Chinese White Dolphins sightings were recorded
during the two sets of surveys in May 2018.
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 May 2018
with the results present in Tables 2.7 and 2.8.

One (1)
Limit Level exceedance was observed for the quarterly dolphin monitoring data
between March and May 2018, whilst no unacceptable impact from the
construction activities of the TM-CLKL Southern Connection Viaduct Section on
Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) was noticeable
from general observations. Due to
monthly variation in dolphin occurrence within the Study Area, it would be more
appropriate to draw conclusion on whether any impacts on dolphins have been
detected related to the construction activities of the TM-CLKL Southern
Connection Viaduct Section in the quarterly EM&A reports, in which
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 2,
9, 16, 23 and 30 May 2018.
Key observations and recommendations during the site
inspections in this reporting period are summarized in Table 2.9.
