Impact Dolphin
Monitoring
During this month of dolphin monitoring, 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.
Daily marine mammal exclusion zone monitoring was undertaken during the
period of marine works under this Contract.
No sighting of the Chinese White Dolphin was recorded in September 2018
during the exclusion zone monitoring.
Environmental
Complaints, Non-compliance & Summons
No complaints, notification of summons or successful prosecution
recorded in the reporting period.
Reporting Change
There was no reporting change in the reporting period.

Future Key Issues
Potential environmental impacts arising from the above upcoming
construction activities in the next reporting month of October 2018 are mainly
associated with dust, noise, 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 (EP-354/2009/A) was issued
on 8 December 2010.

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 2.4. The co-ordinates of all transect lines are
shown in Table 2.11 below ([1]).

conducted under favourable weather conditions (i.e. Beaufort Sea State 3 or
below with good visibility) during the surveys in September 2018. Among the two areas, 95.80 km and 167.88 km
of survey effort were collected from NEL and NWL survey areas,
respectively. The total survey effort
conducted on primary and secondary lines were 190.81 km and 72.87 km,
respectively. The survey efforts are
summarized in Appendix K.
One (1)
group of 2 Chinese White Dolphins was sighted during the two sets of monitoring surveys in September 2018. The dolphin
sighting was made in NWL, while none was sighted in NEL. During the surveys in September 2018, the only sighting was made during on-effort
search and on primary line. None of the
dolphin groups was associated with operating fishing vessel and was not sighted
in the proximity of the Project’s alignment.
The distribution of dolphin sighting during the reporting month is shown
in Figure 2.5.
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 September 2018 are shown in Tables 2.12 & 2.13.

During this month of dolphin monitoring, 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.
Daily 250 m marine mammal exclusion zone
monitoring was undertaken during the period of daytime marine works
activities. No sighting of Chinese White
Dolphin was recorded in September 2018 during the exclusion zone monitoring.
Passive Acoustic Monitoring (PAM) had been
decommissioned as no marine piling works was carried out outside the daylight
hours since September 2015.
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 5, 12, 18 and 27 September 2018.
Key
observations during the site inspections are summarized in Table 2.14.
