Under Contract No. HY/2012/07,
Gammon Construction Limited (GCL) is commissioned by the Highways Department (HyD) to undertake the design and construction of the
Southern Connection Viaduct Section of the Tuen Mun – Chek Lap Kok Link Project (TM-CLK Link Project) while AECOM
Asia Company Limited was appointed by HyD as the
Supervising Officer. For implementation
of the environmental monitoring and audit (EM&A) programme
under the Contract, ERM-Hong Kong, Limited (ERM) has been appointed as the
Environmental Team (ET). ENVIRON Hong
Kong Ltd. was employed by the HyD as the Independent
Environmental Checker (IEC) and Environmental Project Office (ENPO) in
accordance with Environmental Permit No. EP-354/2009/A. Further

January 2014, 10 December 2014 and 13 March 2015, respectively.
The construction phase of the Contract commenced on 31
October 2013 and will tentatively be completed by 2018. The impact monitoring of the EM&A programme, including air quality, noise, water quality and
marine ecological monitoring as well as environmental site inspections,
commenced on 31 October 2013.
This is the Nineteenth Monthly EM&A report
presenting the EM&A works carried out during the period from 1 to 31 May
2015 for the Southern Connection Viaduct
Section in accordance with the Updated EM&A Manual of the
TM-CLK Link Project. As informed by the Contractor, major

Breaches of Action and Limit Levels for Air Quality
No
exceedance of Action and Limit Levels was recorded for construction air monitoring
in the reporting month.
Breaches of Action and Limit Levels for Noise
No
exceedance of Action and Limit Levels was recorded for construction noise
monitoring in the reporting month.
Breaches of Action and Limit Levels for Water Quality
One
(1) exceedance of Action Level for depth-averaged SS during mid-ebb tide was
recorded for water quality monitoring in the reporting month.
Impact Dolphin Monitoring
Whilst one (1) Limit Level
exceedance was observed for the quarterly dolphin monitoring data between March
and May 2015, no unacceptable impact from the construction activities of the
TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins 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, where
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.
Passive Acoustic Monitoring (PAM) was implemented when the marine piling
works were carried out outside the daylight hours in this reporting month. No sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in May 2015 during the exclusion zone
monitoring.
Environmental Complaints, Non-compliance & Summons
No
environmental complaint, notification of summons and successful prosecution was
received in the reporting month.

Future Key
Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of June 2015 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.

One (1) Action level exceedance of depth-averaged SS
during mid-ebb tide was recorded on 19 May 2015 at monitoring station
SR4a. Actions were taken in accordance
with the Event Action Plan as presented in Appendix L.
Apart from the observed exceedance, results of
depth-averaged turbidity on 14 May 2015 at mid-flood tide, and depth-averaged
SS on 14, 16, 19 and 23 May 2015 during mid-ebb and/or mid-flood tides were
higher than the corresponding Action Levels at some of the impact stations and
sensitive receivers, but the results were lower than 120% of the upstream
control at the same tide of the same day (Table
2.10). As such, the above
depth-averaged turbidity and depth-average SS results were not regarded as
exceedance. No action is thus required
to be undertaken in accordance with the Event Action Plan (Appendix L).

The
Action and Limit levels of dolphin impact monitoring are shown in Appendix D. The
Event and Action plan is presented in Appendix L.
A
total of 301.70 km of survey effort was collected, with 98.7% of the total
survey effort being conducted under favourable
weather conditions (i.e. Beaufort Sea State 3 or below with good visibility)
during the surveys of May 2015. Among
the two areas, 114.90 km and 186.80 km of survey effort were collected from NEL
and NWL survey areas respectively. The
total survey effort conducted on primary and secondary lines were 219.76 km and
81.94 km respectively. The survey
efforts are summarized in Appendix K.
No
Chinese White Dolphins were sighted during the two sets of monitoring surveys
in May 2015.
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 2015 are shown in Tables 2.13 & 2.14.

Whilst
one (1) Limit Level exceedance was observed for the quarterly dolphin
monitoring data between March and May 2015.
No unacceptable impact from the construction activities of the TM-CLKL
Southern Connection Viaduct Section on Chinese White Dolphins was noticeable
from general observations during the dolphin monitoring in this reporting
month.
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, where 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 marine works activities being undertaken.
Passive Acoustic Monitoring (PAM) was implemented when the marine piling
works were carried out outside the daylight hours in this reporting month. No sighting of Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) were recorded in May 2015 during the exclusion
zone monitoring.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of June 2015 are mainly associated with dust,
noise, marine water quality, marine ecology and waste management issues.
This
Nineteenth Monthly EM&A Report presents the findings of the EM&A
activities undertaken during the period from 1 to 31 May 2015, in accordance
with the Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/D).
No
Chinese White Dolphins were sighted during the two sets of monitoring surveys
in May 2015. Whilst one (1) Limit Level
exceedance was observed for the quarterly dolphin monitoring data between March
and May 2015, no unacceptable impact from the
construction activities of the TM-CLKL Southern Connection Viaduct Section on
Chinese White Dolphins was noticeable from general observations during the
dolphin monitoring in this reporting month.
The
ET will keep track on the construction works to confirm compliance of
environmental requirements and the proper implementation of all necessary
mitigation measures.
